Abstract
The invention discloses a formula of a novel modified polyvinylidene fluoride. The formula comprises modified polyvinylidene fluoride, a wear-resistant material, an additive and a forming agent, wherein the wear-resistant material is silica powder, the additive is dicumyl peroxide, the forming agent is a silicone lubricant; and the weight percentages of the components are as follows: the modified polyvinylidene fluoride accounts for 50%-70%, the silica powder accounts for 5%-10%, the dicumyl peroxide accounts for 10%-15%, and the silicone lubricant accounts for 15%-25%. The prepared novel modified polyvinylidene fluoride has the effects of high toughness, wear resistance and convenience in forming.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of new modified 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 have outstanding erosion resistance in addition, so the raw material that must use in chemical industry, any metal all can't substitute.PVDF again in Fluroplast-4 physical strength the highest.Along with the depth development of various industries, PVDF is extensively adopted, and has good piezoelectricity, radiation hardness, and thermostability is also fine, so extensively adopted by electron trade, X-former manufacturing.Also be 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.As everyone knows, steel is the necessary material of manufacturing machine, but the strong acid, alkali, salt, the polar solvent aspect that are used in chemical industry are obsolete., perplexing for a long time that the material of this respect is a kind of well not to be 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.All do not reach requirement in effectiveness, performance, work-ing life.The task of top priority must solve the exotic materials of research and development this respect, makes chemical industry obtain stablizing long-range development.
Summary of the invention
The object of the present invention is to provide that a kind of toughness is high, wear-resistant, the prescription of the new modified PVDF being convenient to be shaped.
Technical scheme of the present invention is that a kind of prescription of new modified PVDF comprises modified polyvinilidene difluoroethylene, high-abrasive material, auxiliary agent and binder; Described high-abrasive material is a silica flour, and described auxiliary agent is a dicumyl peroxide, and described binder is a silicone lubricant; Each composition weight proportion accounts for 50%-70% for the modified polyvinilidene difluoroethylene; Silica flour accounts for 5%-10%, and dicumyl peroxide accounts for 10%-15%, and silicone lubricant accounts for 15%-25%.
In preferred embodiment of the present invention, each composition weight proportion of the prescription of said new modified PVDF accounts for 55%-65% for the modified polyvinilidene difluoroethylene, and silica flour accounts for 10%-13%, and dicumyl peroxide accounts for 18%-20%, and silicone lubricant accounts for 7%-12%.
According to the invention is a kind of prescription of new modified PVDF, makes the new modified PVDF that makes have toughness height, wear-resistant, the effect being convenient to be shaped.
Embodiment
Set forth in detail in the face of preferred embodiment of the present invention down, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of prescription of new modified PVDF, comprises modified polyvinilidene difluoroethylene, high-abrasive material, auxiliary agent and binder, and high-abrasive material is a silica flour; Auxiliary agent is a dicumyl peroxide; Binder is a silicone lubricant, and each composition weight proportion accounts for 50%-70% for the modified polyvinilidene difluoroethylene, and silica flour accounts for 5%-10%; Dicumyl peroxide accounts for 10%-15%, and silicone lubricant accounts for 15%-25%.
Further, each composition weight proportion of the prescription of new modified PVDF accounts for 55%-65% for the modified polyvinilidene difluoroethylene, and silica flour accounts for 10%-13%, and dicumyl peroxide accounts for 18%-20%, and silicone lubricant accounts for 7%-12%.
Can debug according to different ratios according to different demands, thereby reach different results of use.
According to the invention is a kind of prescription of new modified PVDF, makes the new modified PVDF that makes have toughness height, wear-resistant, the effect being convenient to be shaped.
The above is merely 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; 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.
