Abstract
The invention discloses a heat-resisting polyethylene terephthalate resin composition and a preparation method thereof. The heat-resisting polyethylene terephthalate resin composition comprises the following raw materials in parts by mass: 66-72 parts of polyethylene terephthalate, 15-18 parts of carbon fibers, 5-10 parts of polyetherketone, 1-3 parts of di(3,5-tertiary butyl-4-hydroxyphenyl) sulfide and 4-6 parts of styrene-acrylonitrile-maleic anhydride copolymers. The resin obtained by reasonably compounding the polyethylene terephthalate, the carbon fibers, the polyetherketone, the di(3,5-tertiary butyl-4-hydroxyphenyl) sulfide and the styrene-acrylonitrile-maleic anhydride copolymers not only has relatively good comprehensive property, but also has good heat resistance, and is capable of resisting high temperature of 200 DEG C.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of heat-resisting pet resin composition and method of making the same.
Background technology
Polyethylene terephthalate is topmost kind in thermoplastic polyester, and it has good mechanical property and resistance to most of solvent, but blemish in an otherwise perfect thing is that its thermotolerance is bad, easily has toxic substance to separate out during the too high heating of temperature.Although existing multiple heat resistant type pet resin composition on market, the improvement that its thermotolerance obtains to a certain extent, its over-all properties is not good.
In sum, how to overcome the deficiencies in the prior art and become existing field problem demanding prompt solution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and propose a kind of heat-resisting pet resin composition and method of making the same, the present invention has excellent thermotolerance and its over-all properties is better.
Technical scheme of the present invention is as follows:
A kind of heat-resisting pet resin composition, comprise the following raw material according to mass fraction meter: polyethylene terephthalate 66-72 part, carbon fiber 15-18 part, polyetherketone 5-10 part, two (3,5-tert-butyl-hydroxy phenyl) thioether 1-3 part, styrene-acrylonitrile-copolymer-maleic anhydride 4-6 part.
Described heat-resisting pet resin composition, comprise the following raw material according to mass fraction meter: polyethylene terephthalate 68 parts, 16 parts, carbon fiber, polyetherketone 6 parts, two (3,5-tert-butyl-hydroxy phenyl) thioether 2 parts, styrene-acrylonitrile-copolymer-maleic anhydride 5 parts.
A kind of preparation method of heat-resisting pet resin composition, comprise the following steps: take each raw material according to quality proportioning, by polyethylene terephthalate, carbon fiber, polyetherketone, two (3,5-tert-butyl-hydroxy phenyl) thioether and styrene-acrylonitrile-copolymer-maleic anhydride be uniformly mixed, extrude by forcing machine, extruder temperature controls at 275-280 DEG C, obtains heat-resisting pet resin composition.
Beneficial effect: the present invention is by polyethylene terephthalate, carbon fiber, polyetherketone, two (3,5-tert-butyl-hydroxy phenyl) thioether and styrene-acrylonitrile-copolymer-maleic anhydride rationally composite, gained resin not only over-all properties is better, but also there is good thermotolerance, can resistance to 200 degree of high temperature.
