Abstract

The invention discloses a formula of high-toughness polyvinylidene fluoride. The formula comprises the following components in percentage by weight: 30 to 60 percent of modified high-toughness polyvinylidene fluoride, 10 to 30 percent of bamboo carbon fiber serving as a toughness resistant material, 15 to 20 percent of dicumyl peroxide serving as an aid and 15 to 20 percent of paraffin serving as a special material. The prepared high-toughness polyvinylidene fluoride has high toughness and high fusion, and achieves an effect of brightness.

Description

A kind of prescription of H.T. PVDF

Technical field

the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of H.T. 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, amalgamation is high and plays the prescription of the H.T. PVDF of brightness effect.

technical scheme of the present invention is: a kind of prescription of H.T. PVDF, comprise modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials, and described anti-toughness material is a bamboo carbon fibre; Described auxiliary agent is a dicumyl peroxide; Described exotic materials is a paraffin, and each composition weight proportion accounts for 30%-60% for the modified polyvinilidene difluoroethylene, and bamboo carbon fibre accounts for 10%-30%; Dicumyl peroxide accounts for 15%-20%, and paraffin accounts for 15%-20%.

In preferred embodiment of the present invention, said bamboo-carbon fibre is to be made up of carbon .

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 bamboo carbon fibre accounts for 20%, and dicumyl peroxide accounts for 15%%, and paraffin accounts for 20%.

The prescription of a kind of H.T. PVDF of the present invention, it is high and play the effect of light to make the new modified PVDF that makes have a toughness height, amalgamation.

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 H.T. PVDF comprises modified polyvinilidene difluoroethylene, anti-toughness material, auxiliary agent and exotic materials; Described anti-toughness material is a bamboo carbon fibre; Described auxiliary agent is a dicumyl peroxide, and described exotic materials is a paraffin, and each composition weight proportion accounts for 30%-60% for the modified polyvinilidene difluoroethylene; Bamboo carbon fibre accounts for 10%-30%; Dicumyl peroxide accounts for 15%-20%, and paraffin accounts for 15%-20%, and said bamboo-carbon fibre is to be made up of carbon.

further specify, and each composition weight proportion of the prescription of said H.T. PVDF accounts for 45% for the modified polyvinilidene difluoroethylene, and bamboo carbon fibre accounts for 20%, and dicumyl peroxide accounts for 15%%, and paraffin accounts for 20%.Can debug according to different ratios according to different demands; Thereby reach different results of use; And dicumyl peroxide makes it that good amalgamation fully arranged between molecule; Paraffin plays the effect of light, and the present invention provides a kind of prescription of H.T. PVDF, and it is high and play the effect of light to make the H.T. PVDF that makes have a toughness height, amalgamation.

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.
