Abstract
The invention discloses a formula of a modified polytetrafluoroethylene-ethylene copolymer. The formula comprises a polytetrafluoroethylene-ethylene copolymer and additives, the additives comprises a light stabilizer, a filler, a tackifier, a coupling agent and a cross-linking agent, the light stabilizer is ethyl 2-cyan-3,3-diphenylacrylate, the filler is glass fibers, the tackifier is polyvinyl acetal, the cross-linking agent is 2.5-dimethyl-2,5-di-tery-butylperoxyhexane, and the coupling agent is methacryloxypropyltrimethoxysilane. The formula allows the prepared modified polytetrafluoroethylene-ethylene copolymer to have the characteristics of good fluidity, high mechanical and physical performances, radiation resistance, good viscosity, stable product performances, low production cost and the like.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of modified Teflon-ethylene copolymer.
Background technology
Tetrafluoroethylene-ethylene copolymer has remarkable chemical resistance, and all corrosion-resistant to all chemical, frictional coefficient is minimum in plastics, also has good electrical property, and its electrical insulating property is temperature influence not, and the title of " King " is arranged.But the poor fluidity of tetrafluoroethylene-ethylene copolymer very easily decomposes, and produces etchant gas during decomposition.The cementability extreme difference of tetrafluoroethylene-ethylene copolymer, usage range is restricted larger.Simultaneously, manufacturing cost is larger in the production process, the unstable properties of the product of producing.
Summary of the invention
The object of the present invention is to provide that a kind of good fluidity, mechanical and physical performance are high, the prescription of radiation hardness, viscosity is good, product performance are stable, production cost is low modified Teflon-ethylene copolymer.
Technical scheme of the present invention is, a kind of prescription of modified Teflon-ethylene copolymer, comprise tetrafluoroethylene-ethylene copolymer and additive, described additive comprises photostabilizer, weighting agent, tackifier, coupling agent and linking agent, described photostabilizer is 2-cyano group-3,3 diphenylacrylate ethanol, described weighting agent is glass fibre, described tackifier are polyvinyl acetal, described linking agent is 2,5-dimethyl-2,5 di-t-butyl hexane peroxide, described coupling agent are methacryloxypropyl trimethoxy silane.
In a preferred embodiment of the present invention, each composition weight percent of the prescription of described modified Teflon-ethylene copolymer is that tetrafluoroethylene-ethylene copolymer accounts for 78.9%-84.6%, 2-cyano group-3,3 diphenylacrylate ethanol account for 1.8%-2.9%, and glass fibre accounts for 8.7%-10.4%, and polyvinyl acetal accounts for 1.3%-2.2%, 2,5-dimethyl-2,5 di-t-butyl hexane peroxide accounts for 1.5%-2.4%, and methacryloxypropyl trimethoxy silane accounts for 2.1%-3.2%.
In a preferred embodiment of the present invention, each composition weight percent of the prescription of described modified Teflon-ethylene copolymer is that tetrafluoroethylene-ethylene copolymer accounts for 80.3%, 2-cyano group-3,3 diphenylacrylate ethanol account for 2.7%, and glass fibre accounts for 10.1%, and polyvinyl acetal accounts for 1.8%, 2,5-dimethyl-2,5 di-t-butyl hexane peroxide accounts for 2.2%, and methacryloxypropyl trimethoxy silane accounts for 2.9%.
