Abstract
The invention discloses a formula of thermally-stable polyvinylidene fluoride. The formula comprises modified polyvinylidene fluoride, a toughness-resistant material, an aid and a special material, wherein the toughness-resistant material is hexaflouropropylene; the aid is a stabilizer; the special material is an antioxidant; the modified polyvinylidene fluoride accounts for 30-60 percent of the total weight of the thermally-stable polyvinylidene fluoride; the hexaflouropropylene accounts for 15-30 percent of the total weight of the thermally-stable polyvinylidene fluoride; the stabilizer accounts for 10-20 percent of the total weight of the thermally-stable polyvinylidene fluoride; and the antioxidant accounts for 15-20 percent of the total weight of the thermally-stable polyvinylidene fluoride. The prepared thermally-stable polyvinylidene fluoride has the effects of high thermal stability, contribution to injection molding and reducing explosion.
Description
Technical field
the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of thermostability 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 thermostability height, helps the blast prescription of thermostability PVDF of effect of injection molded and reduction.
technical scheme of the present invention is: a kind of prescription of thermostability PVDF, comprise modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials, and described anti-toughness material is a hexafluoroethylene; Described auxiliary agent is a stablizer; Described exotic materials is an oxidation inhibitor, and each composition weight proportion accounts for 30%-60% for the modified polyvinilidene difluoroethylene, and hexafluoroethylene accounts for 15%-30%; Stabilizer comprises 10%-20%, oxidation inhibitor accounts for 15%-20%.
in preferred embodiment of the present invention, said stablizer comprises pure polyvinyl chloride resin.
in preferred embodiment of the present invention, each composition weight proportion of the prescription of said new modified PVDF accounts for 45% for the modified polyvinilidene difluoroethylene, and hexafluoroethylene accounts for 25%, stabilizer comprises 15%, and oxidation inhibitor accounts for 15%.
The prescription of
a kind of thermostability PVDF of the present invention makes the thermostability PVDF that makes have the thermostability height, helps the effect that injection molded and reduction are blasted.
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 thermostability PVDF comprises modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials; Described anti-toughness material is a hexafluoroethylene, and described auxiliary agent is a stablizer, and described exotic materials is an oxidation inhibitor; Each composition weight proportion accounts for 30%-60% for the modified polyvinilidene difluoroethylene, and hexafluoroethylene accounts for 15%-30%, stabilizer comprises 10%-20%; Oxidation inhibitor accounts for 15%-20%, and said stablizer comprises pure polyvinyl chloride resin.
further specify; Each composition weight proportion of the prescription of said thermostability PVDF accounts for 45% for the modified polyvinilidene difluoroethylene, and hexafluoroethylene accounts for 25%, stabilizer comprises 15%; Oxidation inhibitor accounts for 15%; Can debug according to different ratios according to different demands, thereby reach different results of use, and hexafluoroethylene can improve thermostability; Stablizer helps injection moulding; Add oxidation inhibitor and make it reduce the oxidized possibility that can produce shear heat and blast, the present invention provides a kind of prescription of thermostability PVDF, makes the new modified PVDF that makes have the thermostability height, helps the effect that injection molded and reduction are blasted.
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.
