Abstract
The invention discloses a formula of high-fused polyvinylidene fluoride, which includes, in weight ratio, 20%-70% of modified polyvinylidene fluoride, 10%-40% of ductile material, 10%-20% of auxiliary and 10%-20% of special material. The ductile material is inorganic. The auxiliary is maleic anhydride. The special material is silicone lubricant. The prepared high-fused polyvinylidene fluoride has the advantages of high ductility, high fusion and convenience in injection molding.
Description
Technical field
the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of high fusion 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 the height that has the toughness height, amalgamation is high and helps the injection molded effect to merge the prescription of PVDF.
technical scheme of the present invention is: a kind of prescription of high fusion PVDF, comprise modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials, and described anti-toughness material is inorganic substance; Described auxiliary agent is a MALEIC ANHYDRIDE; Described exotic materials is a silicone lubricant, and each composition weight proportion accounts for 20%-70% for the modified polyvinilidene difluoroethylene, and inorganic substance account for 10%-40%; MALEIC ANHYDRIDE accounts for 10%-20%, and silicone lubricant accounts for 10%-20%.
in preferred embodiment of the present invention, said inorganic substance comprise permanent white, titanium oxide, aluminum oxide and talcum powder.
in preferred embodiment of the present invention, each composition weight proportion of the prescription of said new modified PVDF accounts for 60% for the modified polyvinilidene difluoroethylene, and inorganic substance account for 10%, and MALEIC ANHYDRIDE accounts for 15%, and silicone lubricant accounts for 15%.
The prescription of
a kind of high fusion PVDF of the present invention makes the height that makes merge the effect that PVDF has toughness height, amalgamation height and helps injection molded.
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 fusion PVDF comprises modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials; Described anti-toughness material is inorganic substance; Described auxiliary agent is a MALEIC ANHYDRIDE, and described exotic materials is a silicone lubricant, and each composition weight proportion accounts for 20%-70% for the modified polyvinilidene difluoroethylene; Inorganic substance account for 10%-40%; MALEIC ANHYDRIDE accounts for 10%-20%, and silicone lubricant accounts for 10%-20%, and said inorganic substance comprise permanent white, titanium oxide, aluminum oxide and talcum powder.
further specify, and said high each composition weight proportion of prescription that merges PVDF accounts for 60% for the modified polyvinilidene difluoroethylene, and inorganic substance account for 10%, and MALEIC ANHYDRIDE accounts for 15%, and silicone lubricant accounts for 15%.Can debug according to different ratios according to different demands; Thereby reach different results of use; And inorganic substance make it that good amalgamation fully arranged between molecule, and MALEIC ANHYDRIDE makes it that good amalgamation fully arranged between molecule, and silicone lubricant helps injection molded; The present invention provides a kind of prescription of high fusion PVDF, makes the height that makes merge the effect that PVDF has toughness height, amalgamation height and helps injection molded.
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.
