Description
Technical field
The present invention relates to a kind of material modified technical field, and in particular to a kind of wear-resisting polypropene material being modified with modified Teflon and preparation method thereof.
Background technology
Polypropylene has excellent mechanical performance, electrical property, insulating properties etc., and is widely used in the fields such as automobile, building, but the deficiency in terms of its wearability and anti-corrosive properties limits its application.At present, domestic high-abrasive material mainly includes phenolic resin, glass fibre, molybdenum disulfide, carbon fiber etc., but the maximum defect of these materials is that abrasive wear is serious.Polytetrafluoroethylmaterial material has excellent chemical resistance, stability and low friction factor, is widely used in anti-corrosion, the production of high abrasion goods.Polytetrafluoroethylmodified modified acrylic resin is used, polyacrylic wearability and anti-corrosive properties can be improved, and can produce with self-cleaning（Surface not dry linting during friction）Product, such as kitchen tools, packaging, product etc. in electrical equipment shell.Therefore, there is positive effect to polypropylene modification with polytetrafluoroethylene (PTFE).And polytetrafluoroethylene (PTFE) is modified using inorganic fillers such as addition glass fibre, graphite, molybdenum disulfide more than traditional method, but the abrasion of this material are larger, and service life is short, easily causes abrasion to mill couple；In addition, it is generally prepared by the way of physical blending, although this preparation method convenient formation, operating procedure are simple, these inorganic wear resistant filler generally existing density are big, with resin compatible it is poor, easily isolate, bad dispersibility the shortcomings of.
The content of the invention
It is an object of the invention to provide a kind of wear-resisting polypropene material being modified with modified Teflon and preparation method thereof.
Technical scheme is as follows：
A kind of wear-resisting polypropene material being modified with modified Teflon, is prepared from by weight by following components：
Acrylic resin
100 parts,
0.5-2 parts of modified Teflon,
Antioxidant
0.1-0.5 parts,
The modified Teflon is the polytetrafluorethylepowder powder for being coated or being grafted with polybenzoate.
Further scheme, the acrylic resin is at least one of COPP, HOPP.
The antioxidant is four [β-(3,5- di-t-butyl 4- hydroxy phenyls) propionic acid] pentaerythritol esters（Antioxidant 1010）, three-(2,4- di-tert-butyl-phenyl) phosphite esters（Irgasfos 168）, at least one of double octadecyls of β-positive octadecanol ester (antioxidant 1076) of (3,5- di-t-butyl -4- hydroxy phenyls) propionic acid or thio-2 acid.
The polybenzoate is coated or the polytetrafluorethylepowder powder of grafting is prepared from by radiating emulsion method, and its specific preparation method is：
（1）Acrylate monomers are added in polytetrafluoroethylsolution solution and are mixed into mixed emulsion, wherein the percentage by weight of acrylate monomers is 15-50%, and polytetrafluoroethylene (PTFE) is surplus；
（2）Nitrogen is passed through into mixed emulsion 10 minutes, is placed into Co 60 source chamber, under agitation, 100-120min is irradiated with 50Gy/min close rate；
（3）Take out, dry, obtain the polytetrafluorethylepowder powder of polybenzoate cladding or grafting.
It is 1 in mass ratio by styrene and methyl methacrylate that the acrylate monomers, which are,:1 composition；The percentage by weight of the acrylate monomers is 20-45%, and polytetrafluoroethylene (PTFE) is surplus.
Another goal of the invention of the present invention is to provide a kind of preparation method of above-mentioned wear-resisting polypropene material being modified with modified Teflon, 0.1-0.5 parts of 100 parts of acrylic resin, 0.5-2 parts of modified Teflon and antioxidant are added to high-speed mixer and mixing together uniform, then mixing in double screw extruder, extrusion are added, wear-resisting polypropene material is obtained.
The incorporation time of the high mixer is 5-15min；The interval extrusion temperature of each extrusion is 150-170 DEG C, 170-185 DEG C, 175-185 DEG C, 175-185 DEG C, 175-185 DEG C, 180-190 DEG C, 180-195 DEG C, 180-195 DEG C, 180-195 DEG C, 185-200 DEG C respectively in double screw extruder.
It is anti-wear agent come modified polypropene that the present invention, which uses modified Teflon, so as to improve the wearability of polypropylene material；The polypropylene material of preparation can be used as the parts that such as high temperature, high pressure, oil-free lubrication, corrosion are used under extremely harsh conditions.
The present invention carrys out modified Teflon using high polymer polybenzoate as modifying agent, improve the abrasion of polytetrafluoroethylene (PTFE), this is due to the self lubricity that polybenzoate has height, it is possible to resolve the abrasion present in common polytetrafluoroethylene (PTFE) are larger, the problems such as especially having mill couple compared with macrolesion.
Because the high-abrasive material of modified Teflon has minimum average wear coefficient, the characteristics of its polypropylene material being modified is maximum is abrasion performance, do not damage to mill couple, can be widely used for the industrial circle such as machinery, Aeronautics and Astronautics, electronics, electric, application prospect is very wide.
