Abstract
The invention discloses a formula of high-forming polyvinylidene fluoride. The formula comprises modified polyvinylidene fluoride, a tough material, an auxiliary and a special material, wherein the tough material is glass fiber, the auxiliary is titanium dioxide, and the special material is carbon micro-powder; and the modified polyvinylidene fluoride accounts for 10-60% by weight, the glass fiber accounts for 10-40% by weight, the titanium dioxide accounts for 15-25% by weight, and the carbon micro-powder accounts for 15-25% by weight. Through the invention, the high-forming polyvinylidene fluoride has high toughness, is favorable for injection moulding and can realize a conductive effect.
Description
Technical field
the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of high shaping 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 to have the toughness height, help injection molded and can play the prescription of the height shaping PVDF of conductive effect.
technical scheme of the present invention is: a kind of prescription of high shaping PVDF, comprise modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials, and described anti-toughness material is a spun glass; Described auxiliary agent is a titanium white; Described exotic materials is a micropowder, and each composition weight proportion accounts for 10%-60% for the modified polyvinilidene difluoroethylene, and spun glass accounts for 10%-40%; Titanium white accounts for 15%-25%, and micropowder accounts for 15%-25%.
in preferred embodiment of the present invention, said spun glass comprises silicon-dioxide.
in preferred embodiment of the present invention, each composition weight proportion of the prescription of said new modified PVDF accounts for 35% for the modified polyvinilidene difluoroethylene, and spun glass accounts for 30%, and titanium white accounts for 15%, and micropowder accounts for 20%.
The prescription of
a kind of high shaping PVDF of the present invention makes the height shaping PVDF that makes have the toughness height, helps injection molded and can play the effect of conduction.
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 high shaping PVDF comprises modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials; Described anti-toughness material is a spun glass, and described auxiliary agent is a titanium white, and described exotic materials is a micropowder; Each composition weight proportion accounts for 10%-60% for the modified polyvinilidene difluoroethylene, and spun glass accounts for 10%-40%, and titanium white accounts for 15%-25%; Micropowder accounts for 15%-25%, and said spun glass comprises silicon-dioxide.
further specify, and each composition weight proportion of the prescription of said high shaping PVDF accounts for 35% for the modified polyvinilidene difluoroethylene, and spun glass accounts for 30%, and titanium white accounts for 15%, and micropowder accounts for 20%.Can debug according to different ratios according to different demands; Thereby reach different results of use; And spun glass makes it that good amalgamation fully arranged between molecule, and titanium white helps injection molded, adds micropowder and can play electric action; The present invention provides a kind of prescription of high shaping PVDF, makes the height shaping PVDF that makes have the toughness height, helps injection molded and can play the effect of conduction.
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.
