Abstract
The invention discloses a formula of anti-sticking polyvinylidene fluoride. The formula comprises modified polyvinylidene fluoride resin, an initiator, an additive and a chain transfer agent; and the modified polyvinylidene fluoride resin accounts for 18-52% by weight, the initiator accounts for 8-18% by weight, the additive accounts for 14-22% by weight, and the chain transfer agent accounts for 26-42% by weight. Through the invention, a protection layer is formed on the surface of the anti-sticking polyvinylidene fluoride, coagulation is prevented, a lighting effect is realized, the fusion among molecules is perfect, and a conductive effect can be realized.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of anti-glutinous PVDF.
Background technology
PVDF is a kind of fluorocarbon resin of novelty, has very high physical strength and wear resistance, and weathering resistance and thermostability are also fine; Has outstanding erosion resistance in addition; So be chemical industry must the use raw material, any metal all can't be displaced, PVDF is adopted by wide sending out; Have good piezoelectricity, radiation hardness; Thermostability is also fine, so extensively adopted by electron trade, X-former manufacturing, also is used in fields such as aerospace, military field, sea water desaltination, metallurgy, electric wire, electric elements, machinofacture.
But, reach in the requirement of component of machinofacture of some special dimension, or some is insufficient, well-known; Steel is the essential material of manufacturing machine, but the strong acid, alkali, salt, the polar solvent aspect that are used in chemical industry are obsolete,, are perplexing the material of this respect for a long time and are never well being developed; Some material can be used but processing difficulties, and can not use repeatedly, so in the deep-etching chemical industry; Every year is all costly, does not all reach requirement in effectiveness, performance, work-ing life, and the task of top priority must solve the exotic materials of research and development this respect; Make worker employed in a plant nursery's industry obtain stablizing long-range development, therefore, have a lot of enterprises to look for my Suzhou Teflon company to come research and inquirement; Research and develop HS, do the indeformable Fluroplast-4 high performance material of corrosion-resistant, anti-cracking, Teflon company is one of domestic enterprise that researches and develops the high performance fluorine plastics the earliest fortunately, has obtained good development and breakthrough at the sciemtifec and technical sphere of this material; Stablized the quality of product, again and between a lot of enterprise secular cooperation has been arranged, and obtained affirming of they; Thereby deepened better development, in addition, new product is also in constantly researching and developing and test-manufacturing.
It is exactly an example that domestic first hand is produced magnetic force driving pump enterprise, and former life-time service does not have the PVDF of modification mainly to be used on the pump valve, but it does not reach requirement, and it can not get solving at high pressure-temperature, on corrosion-resistant.Customer requirement strong acid media lift 100m can use, but does not reach, actual can only pacing up and down at 50m; Can't replace again with other materials; Obtained sufficient solution afterwards with after our company cooperation, but also can lift farther, longer service life; The withstand voltage lifting more than three times obtained good approval.
Summary of the invention
The object of the present invention is to provide on the surface and form resist, prevent to condense, play the prescription that between light effect, the molecule good amalgamation is arranged and can play the anti-glutinous PVDF of electric action effect.
Technical scheme of the present invention is: a kind of prescription of anti-glutinous PVDF; Comprise modified polyvinilidene difluoroethylene resin, initiator, additive and chain-transfer agent; Each composition weight proportion is that modified polyvinilidene difluoroethylene resin accounts for 18%-52%; Initiator accounts for 8%-18%, and additive accounts for 14%-22%, and chain-transfer agent accounts for 26%-42%.
In preferred embodiment of the present invention, described initiator is a peroxycarbonates.
In preferred embodiment of the present invention, described additive is a calcium zinc.
In preferred embodiment of the present invention, described chain-transfer agent comprises that sorbyl alcohol list palm fibre puts acid esters and methyl esters.
The prescription of a kind of anti-glutinous PVDF of the present invention makes the anti-glutinous PVDF that makes and forms resist on the surface, prevents to condense, play the effect that between light effect, the molecule good amalgamation is arranged and can play electric action.
Embodiment
below in conjunction with setting forth preferred embodiment of the present invention in detail, thereby so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
In one embodiment, a kind of prescription of anti-glutinous PVDF comprises modified polyvinilidene difluoroethylene resin, initiator, additive and chain-transfer agent; Each composition weight proportion is that modified polyvinilidene difluoroethylene resin accounts for 18%-52%, and initiator accounts for 8%-18%, and additive accounts for 14%-22%; Chain-transfer agent accounts for 26%-42%; Described initiator is a peroxycarbonates, and described additive is a calcium zinc, and described chain-transfer agent comprises that sorbyl alcohol list palm fibre puts acid esters and methyl esters.
Further specify, each composition weight proportion of prescription of said anti-glutinous PVDF is that modified polyvinilidene difluoroethylene resin accounts for 46%, and peroxycarbonates accounts for 13%; Calcium zinc accounts for 14%, and sorbyl alcohol list palm fibre is put acid esters and accounts for 9%, and methyl esters accounts for 18%; Can debug according to different ratios according to different demands, thereby reach different results of use, and peroxycarbonates can be so that form resist on the surface; Prevent cohesion, sorbyl alcohol list palm fibre is put acid esters and plays the light effect, and calcium zinc makes can play electric action; The adding methyl esters makes has good amalgamation between its molecule; The present invention provides a kind of prescription of anti-glutinous PVDF, the anti-glutinous PVDF that makes is made form resist on the surface, prevents to condense, play the effect that between light effect, the molecule good amalgamation is arranged and can play electric action.
Embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
