Description
Technical field
The present invention relates to a kind of polyamide compoiste material.
Background technology
Polyamide (PA) is to be obtained by binary acid and diamine or by amino acid through polycondensation, is containing repetition acyl on strand
The resin general name of amine groups.Polyamide can be divided into three classes according to its structure：Fatty polyamide, aliphatic-aromatic polyamide
And aromatic polyamide.Wherein fatty polyamide is wide in variety, and yield is big, is widely used, and this kind of polyamide name is main
It is to be determined by the specific carbon number of synthon.The synthetic method of polyamide can be largely classified into three kinds：Melt polycondensation, boundary
Reduction of area gathers and solid phase.
Polyamide has good mechanical performance, heat-resisting, wear-resistant, chemical resistance, anti-flammability and self lubricity, and
It is easy to process, coefficient of friction is relatively low, be widely used in the fields such as electrical/electronic part, automobile, furniture, building materials and film.
But polyamide is there is also shortcomings, such as water imbibition are larger, the brittle, shock resistance under low temperature and drying regime
Poor, dimensional stability is poor and heat resistance not enough etc., these problems cause the use of polyamide to receive larger limitation,
Therefore in need be targetedly modified to polyamide overcomes these shortcomings.Generally there are a two methods to polyamide modified, one
Kind is modified by chemical method, is such as copolymerized, is grafted, crosslinking；Another kind is physical modification, is referred in whole modifying process
Chemical change does not occur or a kind of method of modifying of the chemical reaction of minimum degree only occurs.
The content of the invention
It is an object of the invention to provide a kind of polyamide compoiste material, the polyamide compoiste material has good wearability
Can, shock resistance is excellent, and heat endurance is good, is very suitable for using as auto parts.
To achieve the above object, the present invention uses following technical scheme：
A kind of polyamide compoiste material, in parts by weight, including following components：
100 parts of fatty polyamide, polyolefin elastomer 21-37 parts, diatomite 34-42 parts, silicon rubber 5-17 parts, filler
7-9 parts, nano material 16-23 parts, PEG-4000 3-5 parts, coupling agent 2-5 parts, compatilizer 1-2 parts；
The nano material is the mixture of nano-zinc borate, nano-zinc sulfide and nano molybdenum disulfide.
Preferably, the mixture that the fatty polyamide is polyamide 6 and the mass ratio of polyamide 46 is 5: 2.
Preferably, the filler is mica powder or montmorillonite.
Preferably, the coupling agent is silane coupler.
Preferably, the compatilizer is that maleic anhydride is grafted compatilizer.
Preferably, the nano material is that nano-zinc borate, nano-zinc sulfide and nano molybdenum disulfide mass ratio are 2: 1: 3
Mixture
The invention has the advantages that it is used in mixed way using by polyamide 6 and polyamide 46, because polyamide 46 has
There is good heat endurance so that composite can still maintain good performance under the high temperature conditions.Silicon rubber is higher
At a temperature of remain to keep good physical property, can to composite provide high temperature protection.Diatomite, it is using kaolin as original
Material, the anhydrous aluminium silicate formed at moderate temperatures through dehydration, faster can go out temperature conduction, so as to the composite wood for being
Material radiates as early as possible in high temperature, so as to improve stability of the composite in high temperature.Nano-zinc borate, nano-zinc sulfide and receive
Rice molybdenum disulfide can equally effectively reduce the coefficient of friction of material, can also reduce material friction pair wear extent.These three
Nano material can form wear-resistant protective layer in friction process, can be formed with abrasive dust, diatomite and POE baroque
High hardness wear-resisting protective layer, so as to improve the anti-wear performance of composite.
