Abstract
The invention discloses a formula of lubricating modified polyvinylidene fluoride. The lubricating modified polyvinylidene fluoride comprises modified polyvinylidene fluoride, a lubricating agent, a stabilizing agent, a plasticizing agent and a wear resisting agent, wherein the lubricating agent is polytetrafluoroethylene, the stabilizing agent is dibasic phosphite ester, the plasticizing agent is polyadipic acid propylidene ester, and the wear resisting agent is modified silicon-aluminum carbon black. According to the invention, the prepared lubricating modified polyvinylidene fluoride is anti-blocking, smooth, wear-resistant and high-plasticity.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of lubricating modification 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 the prescription of a kind of anti, smooth, wear-resistant, lubricating modification PVDF that plasticity is high.
Technical scheme of the present invention is; A kind of prescription of lubricating modification PVDF; Comprise modified polyvinilidene difluoroethylene, lubricant, stablizer, softening agent and anti-wear agent, described lubricant is a tetrafluoroethylene, and stablizer is the dibasic phosphorous acid ester; Softening agent is a polytrimethylene adipate, and anti-wear agent is the modification silica-alumina carbon black.
In preferred embodiment of the present invention; Each composition weight proportion of the prescription of said lubricating modification PVDF accounts for 55%-70% for the modified polyvinilidene difluoroethylene; Tetrafluoroethylene accounts for 8%-12%; The dibasic phosphorous acid ester accounts for 10%-14%, and polytrimethylene adipate accounts for 6%-10%, and the modification silica-alumina carbon black accounts for 6%-9%.
In preferred embodiment of the present invention; Each composition weight proportion of the prescription of said lubricating modification PVDF accounts for 60%-80% for the modified polyvinilidene difluoroethylene; Tetrafluoroethylene accounts for 7%-15%; The dibasic phosphorous acid ester accounts for 6%-10%, and polytrimethylene adipate accounts for 5%-9%, and the modification silica-alumina carbon black accounts for 2%-7%.
According to the invention is a kind of prescription of lubricating modification PVDF, makes the lubricating modification PVDF that makes have anti, smooth, wear-resistant, effect that plasticity is high.
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 lubricating modification PVDF; Comprise modified polyvinilidene difluoroethylene, lubricant, stablizer, softening agent and anti-wear agent; Described lubricant is a tetrafluoroethylene; Stablizer is the dibasic phosphorous acid ester, and softening agent is a polytrimethylene adipate, and anti-wear agent is the modification silica-alumina carbon black.
Further; Each composition weight proportion of the prescription of lubricating modification PVDF accounts for 55%-70% for the modified polyvinilidene difluoroethylene, and tetrafluoroethylene accounts for 8%-12%, and the dibasic phosphorous acid ester accounts for 10%-14%; Polytrimethylene adipate accounts for 6%-10%, and the modification silica-alumina carbon black accounts for 6%-9%.
Further; Each composition weight proportion of the prescription of lubricating modification PVDF accounts for 60%-80% for the modified polyvinilidene difluoroethylene, and tetrafluoroethylene accounts for 7%-15%, and the dibasic phosphorous acid ester accounts for 6%-10%; Polytrimethylene adipate accounts for 5%-9%, and the modification silica-alumina carbon black accounts for 2%-7%.
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 lubricating modification PVDF, makes the lubricating modification PVDF that makes have anti, smooth, wear-resistant, effect that plasticity is high.
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.
