Abstract
The invention discloses a modified polytetrafluoroethylene formula. The formula comprises 500 parts by weight of a polytetrafluoroethylene plastic, and additives, wherein the additives comprise 70-100 parts by weight of an impact modifier, 50-80 parts by weight of a flexibilizer, 40-60 parts by weight of a weather resistant agent, 55-75 parts by weight of a coupling agent and 65-95 parts by weight of a crosslinking agent. The formula which allows the plurality of the additives to be added enables the mechanical strength, the rigidness, the toughness and the weatherability of the polytetrafluoroethylene plastic to be increased, the plastic to resist ageing and resist radiation, the temperature influence to be reduced, the reaction rate to be accelerated, the production cost to be reduced and the product quality to be simultaneously improved.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of modified Teflon.
Background technology
Pure polytetrafluoroethylmaterial material exists that physical strength is little, poor rigidity, elasticity is little, linear expansivity raises and increases with temperature shortcoming, and cold flowability is arranged, particularly having under load and the high-speed condition, its size is unstable, easily produce tension set, cause its application in some field to be limited by very large.For when keeping the polytetrafluoroethylmaterial material premium properties, improve its shortcoming, usually adopt and fill the shortcoming that some inorganicss improve polytetrafluoroethylmaterial material.As add glass fibre, glass powder improves its dimensional stability and wear resistance; Interpolation molybdenumdisulphide or graphite improve its self lubricity etc.Adding a kind of inorganics generally can only improve a kind of corresponding performance, when improving several performance simultaneously such as need, must add several corresponding inorganic substance, but owing to add the total amount of modified material certain limit is arranged, transfinite and to bring difficulty to processing, product percent of pass reduces, and causes product cost to improve, and the improved combination properties of tetrafluoroethylene is not desirable especially simultaneously.
Summary of the invention
The object of the present invention is to provide the prescription of the modified Teflon of a kind of good weatherability, physical strength height, good rigidly, good toughness.
Technical scheme of the present invention is, a kind of prescription of modified Teflon, comprise polytetrafluoroethylplastic plastic and additive, described additive comprises anti-impact modifier, toughner, weather resisting agent, coupling agent and linking agent, and the parts by weight of described each composition are: 500 parts of described polytetrafluoroethylplastic plastics, anti-impact modifier 70-100 part, toughner 50-80 part, weather resisting agent 40-60 part, coupling agent 55-75 part and linking agent 65-95 part.
In a preferred embodiment of the present invention, described anti-impact modifier is acrylonitrile-butadiene-styrene copolymer.
In a preferred embodiment of the present invention, described toughner is that maleic anhydride connects.
In a preferred embodiment of the present invention, described weather resisting agent is ESCALOL 567.
In a preferred embodiment of the present invention, described coupling agent is quadrol propyl group methyl dimethoxysilane.
In a preferred embodiment of the present invention, described linking agent is 2,5-dimethyl-2,5 di-t-butyl hexane peroxide.
Of the present invention is a kind of prescription of modified Teflon, can increase the physical strength of polytetrafluoroethylplastic plastic by adding anti-impact modifier, the performances such as rigidity, toughner can improve the toughness of polytetrafluoroethylplastic plastic, make polytetrafluoroethylplastic plastic that the phenomenon of embrittlement can not occur, weather resisting agent can improve the weather resistance of polytetrafluoroethylplastic plastic, make plastics ageing-resistant, radioprotective, and reduce the impact of temperature, coupling agent and linking agent then can make polytetrafluoroethylplastic plastic accelerate reflection speed in modifying process, Decrease production cost can also improve the quality of products simultaneously.
