Description
Technical field
The invention belongs to field of material technology, particularly a kind of nanoparticle reinforced polyurethane foam and preparation method thereof.
Background technology
Urethane foam, be that isocyanic ester and oxy-compound are made through polymerization foaming, can be divided into soft and hard two class by its hardness, wherein soft is principal item.In general, it has splendid elasticity, flexibility, elongation and compressive strength; Chemical stability is good, resistance to many solvents and oils; High abrasion resistance, comparatively large 20 times of natural sponge; Also having the excellent performance such as processibility, heat insulating ability, binding property, be a kind of cushioning material of excellent property, but price is higher.
Urethane foam is except expensive, and outside raw material is in short supply, maximum defect is that its heat resistance and fire resistance are poor, and temperature uses higher than under the environment of 100 DEG C, comparatively unfavorable.
Modified rigid polyurethane foam, is one of effective means of reinforced polyurethane foam performance, especially makes up the heat resistance of urethane foam.
Nanoparticle refers to the particle of granularity between 1-100nm (nanoparticle is also known as ultrafine particulate).Belong to the category of colloidal particle size.They are in the transition zone between cluster and macro object, are between microsystem and meta system, are by the few atom of number or molecular group, therefore their both atypical microscopic system also atypical macrosystems.
Nanoparticle should have some strange physics-chem characteristics.The feature that nanoparticle is different from macro object structure is, its surface-area accounts for very large proportion, and surface atom is both without the amorphous layer of long-range order without short-range order.Can think that the state of nanoparticle surface atom is closer to gaseous state, and the atom of inside particles may in orderly arrangement.Even so, because particle diameter is little, surface curvature is large, the Gilibs pressure that inner generation is very high, can cause certain distortion of internal structure.This constitutional features of nanoparticle makes it have the effect of following four aspects.1. volume effect; 2. surface effects; 3. quantum size effect; 4. macro quanta tunnel effect.
Nanoparticle can as improving the material modified of urethane foam over-all properties.
Summary of the invention
The technical problem that the present invention solves: for above-mentioned deficiency, overcome the defect of prior art, the object of this invention is to provide a kind of nanoparticle reinforced polyurethane foam and preparation method thereof.
Technical scheme of the present invention: a kind of nanoparticle reinforced polyurethane foam, is prepared from by the raw material of following parts by weight:
Polyaminoester emulsion 70-90 part, nano-nickel powder 1-3 part, nano-calcium carbonate 5-10 part, Potassium Persulphate 3-8 part, nano zine oxide 2-6 part, tetraethoxy 5-10 part and sulphide amino zinc formate 2-6 part.
As preferably, described porous plastics is prepared from by each component of following mass fraction: polyaminoester emulsion 75-85 part, nano-nickel powder 2-3 part, nano-calcium carbonate 6-9 part, Potassium Persulphate 5-7 part, nano zine oxide 3-5 part, tetraethoxy 6-9 part and sulphide amino zinc formate 4-5 part.
As preferably, described porous plastics is prepared from by each component of following mass fraction: polyaminoester emulsion 81 parts, nano-nickel powder 2 parts, nano-calcium carbonate 7 parts, Potassium Persulphate 6 parts, nano zine oxide 4 parts, tetraethoxy 7 parts and sulphide amino zinc formate 4 parts.
A preparation method for nanoparticle reinforced polyurethane foam, preparation process is as follows:
(1) each raw material is accurately taken;
(2) put into injection moulding machine after being mixed by raw material shaping, barrel temperature 80 DEG C-155 DEG C, injection pressure 55-105Mpa, die temperature 55 DEG C-85 DEG C, dwell time 35-80s, cooling time 45-110s;
(3) after injection moulding machine cooling forming, nanoparticle reinforced polyurethane foam is namely obtained.
As preferably, in step (2), injection pressure is 72Mpa, dwell time 52s.
Beneficial effect: nanoparticle reinforced polyurethane foam provided by the invention is the surface effects and the volume effect that utilize nanoparticle, and the excellent physicals of nano material itself carries out modification to the performance of urethane foam.Nanoparticle is easy to generate good interface relative to the small size of cell wall and stronger surfactivity thereof, there is in unit volume more number of particles and play the effect of nucleator, make that cell density is larger, abscess is less, this enhancing for porous plastics has very large potentiality.The nanoparticle that the present invention adopts is nano-nickel powder, nano-calcium carbonate and nano zine oxide, three kinds of nanoparticles all have compound action, its advantage performance is not only expanded further with the urethane foam after this modification, such as weathering resistance, heat retaining property and water resisting property, also compensate for its deficiency in compressive property and resistance to elevated temperatures.
Therefore, nanoparticle reinforced polyurethane foam provided by the invention further increases the advantage performance of urethane foam, and improves its physicals and resistance to elevated temperatures.
