Abstract
The invention discloses a formula of anti-coking polyvinylidene fluoride. The formula comprises modified polyvinylidene fluoride, an anti-coking agent, a cross-linking agent and a solubilizer, wherein the anti-coking agent is o-phthalic anhydride, the cross-linking agent is di-t-butyl peroxide, and the solubilizer is polysorbate and fatty acid ethoxylate; and the modified polyvinylidene fluoride accounts for 40%-50%, the o-phthalic anhydride accounts for 13%-17%, the di-t-butyl peroxide accounts for 11%-14%, the polysorbate accounts for 17%-18%, and the fatty acid ethoxylate accounts for 8%-11%. The prepared anti-coking polyvinylidene fluoride has the advantages of excellent dielectric property, impact resistance, high chemical stability and high using temperature.
Description
Technical field
the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of anti-scorch 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.
Still will reach in the requirement of component of machinofacture of some special dimension, or some be insufficient
; As everyone knows, 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;, perplexing the material of this respect for a long time and never well 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 worker employed in a plant nursery's industry obtain stablizing long-range development; Therefore, there are 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; Fortunately Teflon company is one of domestic enterprise that researches and develops the high performance fluorine plastics the earliest, has obtained good development and breakthrough at the sciemtifec and technical sphere of this material, has stablized the quality of product; Again and between a lot of enterprise secular cooperation is 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 have superior dielectric properties, the prescription of shock-resistant, chemicalstability is high and use temperature is high anti-scorch PVDF.
technical scheme of the present invention is: a kind of prescription of anti-scorch PVDF; Comprise modified polyvinilidene difluoroethylene, scorch retarder, linking agent and solubilizing agent, described scorch retarder is a Tetra hydro Phthalic anhydride, and described linking agent is a ditertiary butyl peroxide; Described solubilizing agent is polysorbate and polyoxyethylene carboxylate; Each composition weight proportion accounts for 40%-50% for the modified polyvinilidene difluoroethylene, and Tetra hydro Phthalic anhydride accounts for 13%-17%, and ditertiary butyl peroxide accounts for 11%-14%; Polysorbate accounts for 17%-18%, and polyoxyethylene carboxylate accounts for 8%-11%.
in preferred embodiment of the present invention, said polysorbate is by sorbitan monooleate and ethylene oxide reaction system.
are in preferred embodiment of the present invention; Each composition weight proportion of the prescription of said anti-scorch PVDF accounts for 43% for the modified polyvinilidene difluoroethylene; Tetra hydro Phthalic anhydride accounts for 16%; Ditertiary butyl peroxide accounts for 13%, and polysorbate accounts for 17%, and polyoxyethylene carboxylate accounts for 11%.
The prescription of
a kind of anti-scorch PVDF of the present invention, make the anti-scorch PVDF that makes have superior dielectric properties, shock-resistant, chemicalstability is high and use temperature is high.
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-scorch PVDF comprises modified polyvinilidene difluoroethylene, scorch retarder, linking agent and solubilizing agent; Described scorch retarder is a Tetra hydro Phthalic anhydride, and described linking agent is a ditertiary butyl peroxide, and described solubilizing agent is polysorbate and polyoxyethylene carboxylate; Each composition weight proportion accounts for 40%-50% for the modified polyvinilidene difluoroethylene; Tetra hydro Phthalic anhydride accounts for 13%-17%, and ditertiary butyl peroxide accounts for 11%-14%, and polysorbate accounts for 17%-18%; Polyoxyethylene carboxylate accounts for 8%-11%, and said polysorbate is by sorbitan monooleate and ethylene oxide reaction system.
further specify; Each composition weight proportion of the prescription of said anti-scorch PVDF accounts for 43% for the modified polyvinilidene difluoroethylene, and Tetra hydro Phthalic anhydride accounts for 16%, and ditertiary butyl peroxide accounts for 13%; Polysorbate accounts for 17%, and polyoxyethylene carboxylate accounts for 11%.Can debug according to different ratios according to different demands; Thereby reach different results of use, and Tetra hydro Phthalic anhydride has superior dielectric properties, ditertiary butyl peroxide has shock-resistant; Polysorbate has the chemicalstability height, and polyoxyethylene carboxylate has the use temperature height.The present invention provides a kind of prescription of anti-scorch PVDF, make the anti-scorch PVDF that makes have superior dielectric properties, shock-resistant, chemicalstability is high and use temperature is high.
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.
