• (e) Abkühlen des Polylactids unter Bildung des fertigen Polymer-Formteils.

In addition, such a material can be used, for example, in a method for producing a molded polymer part with a polymer matrix formed entirely or predominantly with a proportion of at least 50% by mass of polylactide and having a higher heat resistance than pure polylactide. This procedure consists of the following steps:

• (a1) plasticizing the polylactide and adding at least 0.5% by mass of at least one finely particulate solid with a particle size between 0.5 μm and 50 μm from the group of sheet silicates and lignin with a melting temperature above that of the polylactide in the plasticized polylactide as well as dispersing the finely particulate solid into the plasticized polylactide, or
• (a2) plasticizing the polylactide mixed or premixed with at least one finely particulate solid from the group of sheet silicates and lignin with a melting temperature above that of the polylactide;
• (c) transferring the plasticized polylactide with the finely particulate solid dispersed therein into a molding tool with a lower and an upper tool;
• (d) solidification of the polylactide with the finely particulate solid dispersed therein, the polylactide being held at least in some areas at a temperature between 70 ° C. and 120 ° C. for a period of at least 2 s;
• (e) cooling the polylactide to form the finished polymer molded part.

In this process, the polylactide with the finely particulate solid dispersed therein is, after maintaining its temperature between 70 ° C. and 120 ° C. in the mold, with the formation of the finished polymer molded part to a temperature of at most 60 ° C is cooled by opening the mold and the mold part located therein is cooled on its exposed surface and / or the mold itself is cooled so that the edge areas of the mold part do not melt again. Polylactide (polylactic acid, PLA) is an example of a natural polymer which is already widely used to replace synthetic polymers. Polylactide is currently primarily used for the production of films, e.g. B. for agriculture, or for the packaging of food and hygiene articles, textile fibers and more or less dimensionally stable molded parts such. B. used in the form of bowls or cups for packaging purposes. Polylactide has thermoplastic properties and has a glass transition temperature of about 50 ° C to 55 ° C and a melting point in the range of about 150 ° C.

An example of such a material is a plasticizable plastic material that can be processed by means of thermoplastic processing methods, which has a proportion of at least one natural polymer from the group polylactide, polyhydroxyalkanoates, in particular polyhydroxybutyrates, polyhydric valerates and butyrate / polyvalerate copolymers, cellulose esters, in particular Cellulose acetates, cellulose propionates and cellulose acetobutyrates, lignin and starch including mixtures and / or derivatives thereof. In order to improve the material properties, such as in particular the impact strength, of the plastic material, the plastic material also contains a proportion of at least one polyamide based on dimer fatty acid. A polymer molding can be produced from such a plastic material using a process in which the natural polymer and the polyamide based on dimer fatty acid, optionally with the addition of a finely particulate solid and / or in particular natural reinforcing fibers, are fed into an extruder in which Extruder is plasticized and homogenized and then discharged from the extruder and cooled, in particular it can be granulated. This plastic material and a molded polymer part produced from it have improved material properties, such as, in particular, increased impact strength. The aforementioned polyamides based on dimer fatty acid are known as such and are currently used primarily as hot melt adhesives. They can largely be obtained from natural raw materials, so that this plastic material can essentially be obtained entirely or at least for the most part from renewable raw materials. This plastic material is just as biodegradable as the natural polymer used or its derivatives and / or mixtures or blends itself. In this context, “dimer fatty acids” are oligomeric fatty acids which are known as such by thermal and / or catalytic Dimerization of unsaturated fatty acids can be synthesized. In the course of such a dimerization, two (or even three) unsaturated fatty acids are linked to one another, such trimers and also unreacted monomers can be separated off, e.g. B. by means of thermal separation processes, such as distillation or rectification. The dimers obtained are branched and can be cyclic or acyclic. The term “cyclic and / or acyclic dimer fatty acid units” of the polyamide used for this plastic material refers to dimer fatty acids whose carboxy groups (COOH-) have been converted to amide groups (-CO-NH-) by reaction with amino groups. This plastic material preferably consists largely of renewable raw materials, which is why, in a preferred embodiment, dimers made from natural fatty acids, such as oleic acid (oleic acid, cis-9-octadecenoic acid, C ₁₈ H ₃₄ O ₂ , CAS No. 112-80-1) and Erucic acid (erucic acid, cis-13-docosenoic acid, C ₂₂ H ₄₂ O ₂ , CAS No. 112-86-7) can be used. Of course, other mono- or polyunsaturated fatty acids, such as palmitoleic acid, linolenic acid, arachidonic acid, etc., can also be used for the dimer fatty acids. Such natural fatty acids can e.g. B. from the seeds of soy, rapeseed, sunflower, sea kale, hemp, flaxseed, walnut and the like.

In 1 is a first embodiment of a firework rocket 10 shown schematically.

In this embodiment the fireworks rocket comprises 10 a cap 11 , which is designed according to a first embodiment, a rocket jacket 12th , which is designed according to a first embodiment, a propellant 13 and an effect set 14th .

In 1 on the left is the firework rocket 10 shown in longitudinal section along the lines II, the cap on the top right 11 alone in a view from below, and the rocket jacket at the bottom right 12th alone in a view from below.

The cap 11 includes a cap body 15th and a cap stiffener 16 . The rocket jacket 12th comprises a jacket body 17th and a jacket stiffening agent 18th . The cap body 15th has essentially the form of a Cone, and the mantle body 17th has, for example, essentially the shape of a cylinder or a tube or a sleeve.

The mantle body 17th is separate from the cap body 15th educated.

The cap body 15th has an inside 15i on. The mantle body 17th has a cavity 171 , an upper end face 17o and a lower face 17u on. The cavity 171 forms in the upper face 17o an upper opening and in the lower face 17u a lower opening.

The propellant 13 protrudes from below through the lower opening partially into the cavity 171 and seal the lower opening. The effect set 14th is in the cavity 171 above the propellant 13 arranged.

The cap body 15th closes the upper opening so that the inside 15i to the cavity 171 points out.

For this purpose is the cap 11 with the rocket jacket 12th connected by the cap body 15th so on the jacket body 17th is set that the lower edge area of the cap body 15th close to the upper edge of the upper face 17o and is glued to it.

In this embodiment of the cap 11 has the inside 15i exemplarily the shape of a funnel, which extends from the cavity 171 tapered away.

The cap stiffener 16 is on the inside 15i arranged. The cap stiffener 16 includes a first web 161 , exemplified as a triangular wall 161 is formed in an axial plane of the cap body 15th lies. Here is with “Axial plane of the cap body 15th “Meant a plane that is the longitudinal axis of the conical cap body 15th contains. The bridge 161 extends from the in 1 left side of the inside 15i up to the diametrically opposite right side of the inside 15i . The first bridge is thus located 161 at a first and a second point on the inside 15i where these places are different.

In this embodiment of the cap 11 is the cap stiffener 16 monolithic with the cap body 15th trained, so that the bridge 161 monolithic with the cap body 15th is trained. So is the first bridge 161 on the inside 15i and attached to the first and second locations. Cap stiffener 16 and cap body 15th are formed by a single component which, for example, was manufactured directly as such from bioplastics by injection molding.

In this embodiment of the rocket jacket 12th exhibits the jacket body 17th an outer jacket wall 17a and a jacket wall 17i who have favourited an inner jacket wall 17i represents, on. The inner mantle wall 17i has, for example, essentially the shape of a cylinder and surrounds the cavity 171 in the circumferential direction, and the outer shell wall 17a has, for example, essentially the shape of a cylinder and surrounds the inner jacket wall 17i in the circumferential direction at a distance. Thus, between the jacket walls 17a , 17i an annular gap is formed. This gap is open at its lower end and closed at its upper end, since there the jacket walls 17a , 17i and an annular connecting wall is monolithically formed with one another and connected in a materially bonded manner.

The jacket stiffener 18th is on the inner and outer shell wall 17i , 17a arranged. The jacket stiffener 18th includes eight bars 181 each of which is exemplified as a rectangular wall 181 is formed in an axial plane of the jacket body 17th lies. Here is with “axial plane of the casing body 17th “Meant a plane which is the longitudinal axis of the cylindrical shell body 17th contains. The bridges 181 are arranged evenly around the longitudinal axis, i.e. at angular intervals of 45 °. Every bridge 181 extends from the to the inner shell wall 17i pointing inside of the outer shell wall 17a up to the outer shell wall 17a to and from the cavity 171 facing away outside of the inner shell wall 17i . Thus every bridge lies 181 at one point on the inner mantle wall 17i and at one point on the outer shell wall 17a where all these places are different.

Every bridge 181 is monolithic with the jacket walls 17a , 17i and thus with the jacket body 17th educated. So every jetty is 181 on the inner and outer shell wall 17i , 17a and a first and a second location on the inner shell wall 17i and a first and a second location on the outer shell wall 17a attached, and is the jacket stiffener 18th monolithic with the mantle body 17th educated. Sheath stiffening agent 18th and sheath body 17th are formed by a single component which, for example, was manufactured directly as such from bioplastics by injection molding.

cap 11 and rocket jacket 12th together form a housing 19th for the fireworks rocket 10 .

The propellant 13 is at its upper edge with that of the cavity 171 pointing inside of the inner jacket wall 17i glued.

In this embodiment of the firework rocket 10 and in this embodiment of the housing 19th is the cap stiffener 16 separate from the jacket stiffening agent 18th educated.

In 2 is a second embodiment of the firework rocket 10 shown schematically, but only the housing 19th without propellant 13 and effect set 14th . This embodiment is similar to the first embodiment, so that above all the differences are explained in more detail below.

Down in 3 can be seen that the bridge 162 from the top of the inside 15i up to the diametrically opposite lower side of the inside 15i extends. In addition, the bridges cross 161 , 162 on the longitudinal axis of the cap body 15th and are formed there monolithically with one another and are firmly connected. The second web is thus located 162 at a third and a fourth point on the inside 15i as well as on the first bridge 161 where these places are different.

In this embodiment the cap stiffener is 16 separate from the cap body 15th trained, so that every bridge 161 , 162 separate from the cap body 15th is trained. Every bridge 161 , 162 is with the inside 15i glued. So is the first bridge 161 on the bottom 15th and attached to the first and second locations is the second web 162 on the bottom 15th and the third and fourth locations, and is the cap stiffener 16 on the cap body 15th attached. Cap stiffener 16 and cap body 15th are formed by two separate components, each made of bioplastics by injection molding, joined and glued together.

The crossing bridges 161 , 162 They also form a star with four rays, with each ray on the inside 15i is applied. In addition, the beams are arranged uniformly to one another, namely in pairs at equal angles of 90 ° around the longitudinal axis of the cap body 15th around. In addition, each beam has a first end - namely the radially outer end in each case - on the inside 15i and with a second end - namely the radially inner end in each case - at the second ends of the remaining rays.

In 4th is a third embodiment of the firework rocket 10 shown schematically. These Embodiment is similar to the first embodiment, so that the differences are explained in more detail below in particular.
