Below in conjunction with detailed description of the invention, the present invention is described in further detail.
Detailed description of the invention
High glaze nylon reinforcements of the present invention, it is by following raw material preparation by weight percentage
Become:
PA6 60-70%,
Glass microballoon 10-15%,
Coupling agent 0.2-1%,
Composite nucleating agent 0.5-1%,
Antioxidant 0.2-0.8%,
Flow ability modifying agent 0.5-1.5%,
Glass fibre 15-25%；
Wherein, the percetage by weight summation of above-mentioned raw materials is 100%.
" PA6 " mentioned in the present invention refers to polyamide 6.Owing to the viscosity of PA6 is very sensitive for variations in temperature,
And the shrinkage factor of PA6 is had a certain impact by viscosity.Therefore, the nylon material moderate in order to obtain shrinkage factor, institute of the present invention
In the high glaze nylon reinforcements stated, as further scheme, the viscosity of described PA6 is 2.3-2.52dl/g.
In high glaze nylon reinforcements of the present invention, as further scheme, described flow ability modifying agent is silicon
In ketone powder, dendritic, PE wax, TAF powder, one or more are with any ratio mixing.Preferably, flow ability modifying agent is
Above two is with compounding.
High glaze nylon reinforcements of the present invention uses composite nucleating agent, PA material internal crystal grain can be made equal
Even distribution, crystallizes more perfect, better crystallinity degree, obtains more excellent mechanical property and dimensionally stable during injecting products product
Property.In high glaze nylon reinforcements of the present invention, it is preferred that described composite nucleating agent selected from nano silicon,
(product type that Clariant Corporation produces is for 30000 mesh superfine talcum powders, sodium benzoate, long-chain linear saturated carboxylic acid sodium salt
NAV101) more than two or three in is with any ratio mixing.Wherein, optimal, use at least one inorganic nucleator with extremely
Few a kind of organic nucleating agent is combined, such as, can be the composite nucleating agent or 30000 of nano silicon and sodium benzoate
Mesh superfine talcum powder and the composite nucleating agent of sodium benzoate.Should be the composite nucleating agent of inorganic nucleator and organic nucleating agent, two
Collaborative effect is had between person.Such as, in the composite nucleating agent of nano silicon and sodium benzoate, due to nanometer titanium dioxide
Silicon exist, sodium benzoate in PA6 matrix will not undue concentration, agglomeration reduce, make nucleation excessively to concentrate, be conducive to
Improve the mechanical property of PA6；And the existence of sodium benzoate, make again nano silicon rise while potentiation, PA6 can be
Faster crystallize in the presence of nucleator, it is thus achieved that ratio is individually added into the mechanical property that nano silicon is more excellent.
Owing to due to PA6 water absorption relatively greatly, dimensional stability is poor, and intensity is not as good as metallic aluminium, limits it at some
Application in structural material；The mechanical property of PA 6 depends primarily on chemical bond and the intermolecular force of its molecular backbone；Add
After adding certain filler, the water absorption rate of PA6 declines, and dimensional stability improves, and intensity is affected by filling intensity and affine degree and
Corresponding rising.Roving glass fiber is to be interleaved with each other lack of alignment together in the composite, and multiple unlike short glass fiber
Streamwise arrangement in condensation material；Compared with short glass fiber composite, the most this lack of alignment state and Length of Glass Fiber
Increase, make roving glass fiber composite material exhibits go out higher mechanical property, excellent thermostability, fatigue durability and wearability, and
Preferably fillibility, low warpage properties and isotropism etc.；Owing to long stapled fibrous termination is less, compare short glass fiber composite
Contributed in performance excellent.Therefore, in high glaze nylon reinforcements of the present invention, described glass fibre is
Alkali-free roving glass fiber, a diameter of 5-14 μm of alkali-free roving glass fiber.Along with the raising of glass fiber content, on the arbitrary cross section of PA composite
Glass increased number, when by impulsive force, the stress of material internal is disperseed, and the mean stress that every glass is subject to subtracts
Few, so more energy can be absorbed during fracture of composite materials so that impact strength becomes big.Meanwhile, along with glass fiber content
Increasing, the matrix between glass and glass is thinning, is more beneficial for the stress transmission at material internal, and meanwhile, the stress of glass is more
Add all so that the impact property of composite is improved.Can also learn that the bending property of PA6 resin is for glass simultaneously
Addition very sensitive.With pure PA6 resin-phase ratio, glass fibre reinforced composite material under external force, the arbitrary cross section of composite
On have substantial amounts of glass bear external force, and to make extraction or the fracture of these glasses, need to apply bigger load and go to overcome glass
Motive power between fibre and matrix material.Therefore, the addition of glass improves the hot strength of composite and bends strong
Degree.
In high glaze nylon reinforcements of the present invention, as further scheme, described coupling agent is that silane is even
Join agent, mix with any ratio for one or more in amino silicane coupling agent, epoxy silane coupling.
In high glaze nylon reinforcements of the present invention, as further scheme, described antioxidant is hindered phenol
Kind antioxidant and phosphoric acid ester antioxidant are that 1:1 is compounding according to weight ratio to be formed.
Glass microballoon (GB), as a kind of novel silicate material, is shaped as the spherical of rule, and draw ratio is fixed, simultaneously
Have light weight, low heat conduction, nontoxic, do not fire, chemical stability is good, high dispersive, sound insulation, high-low temperature resistant, electrical insulating property and thermally-stabilised
Property the advantage high glaze of the present invention nylon reinforcements such as good in.The research of the present invention finds: glass microballoon conduct
A kind of silicate fillers, surface, with the polar group such as hydroxyl etc. of certain content, has preferably with the PA6 matrix with polarity
Interface interaction, PA6 can be served enhancing simultaneously and increase firm effect；Therefore, add glass microballoon and can make material flowability
More preferably, thus so that surface gloss is more preferable during injecting products product, go floating fine effect obvious, make surface smooth.Preferably
, the glass microballoon granularity used in the present invention is 10-250 micron, wall thickness 1-2 micron.
A kind of preparation method of high glaze nylon reinforcements, this preparation method comprises the following steps:
1) raw material disposal and mixing: dried by PA6 according to composition of raw materials amount, controls moisture below 0.04%；Then
Add with coupling agent in high speed mixer to stir and mix, obtain mixture；
2) in said mixture, it is sequentially added into glass microballoon, antioxidant, composite nucleating agent, flow ability modifying agent, continues to stir
Mix and make each component fully dispersed uniformly, obtain premix material；
3) melt extrude: above-mentioned premix material is added in double screw extruder and melt extrudes；
4) pelletize and post processing: obtain finished product after the material after extrusion is sequentially passed through cooling, air-dried, pelletizing, packaging.
The research of the present invention finds, improves screw speed and increase the active force between glass and resin, it is easier to
Causing the fracture of glass, Length of Glass Fiber reduces accordingly, and mechanical property can decline accordingly.Therefore, in order to ensure the mechanics of PA material
Performance；In the preparation method of high glaze nylon reinforcements of the present invention, it is preferred that step 3) in, melt extrude temperature
