Abstract
The invention discloses a formula of explosion-proof polyvinylidene fluoride, which includes 25%-65% of coupling agent, 4%-12% of inorganic initiator, 12%-22% of auxiliary, 6%-14% of nucleating agent and 13-17% of special material. The prepared explosion-proof polyvinylidene fluoride has the advantages that organic combination of materials is enhanced, injection molding is convenient, stability is high and explosion occurrence is reduced.
Description
Technical field
the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of blast protection 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 combination with strongthener, help injection molded, stability is higher and reduce the prescription of the blast protection PVDF of the effect of blasting.
technical scheme of the present invention is: a kind of prescription of blast protection PVDF; Comprise coupling agent, no organic initiators, auxiliary agent, nucleator and exotic materials; Described coupling agent accounts for 25%-65%, and no organic initiators accounts for 4%-12%, and auxiliary agent accounts for 12%-22%; Nucleator accounts for 6%-14%, and exotic materials accounts for 13%-17%.
in preferred embodiment of the present invention, said coupling agent is epoxy 18 fat fourth fat.
in preferred embodiment of the present invention, said no organic initiators is a Potassium Persulphate.
in preferred embodiment of the present invention, said auxiliary agent is a Vestolen PP 7052.
in preferred embodiment of the present invention, said nucleator is an azimidobenzene.
in preferred embodiment of the present invention, said exotic materials is a phosphorous acid ester.
in preferred embodiment of the present invention, each composition weight proportion of the prescription of said blast protection PVDF is that epoxy 18 fat fourth fat account for 47%, and Potassium Persulphate accounts for 8%, and Vestolen PP 7052 accounts for 18%, and azimidobenzene accounts for 11%, and phosphorous acid ester accounts for 16%.
The prescription of
a kind of blast protection PVDF of the present invention, have strongthener combination, help injection molded, stability is higher and reduce the effect blast.
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 blast protection PVDF comprises coupling agent, no organic initiators, auxiliary agent, nucleator and exotic materials; Described coupling agent accounts for 25%-65%, and no organic initiators accounts for 4%-12%, and auxiliary agent accounts for 12%-22%; Nucleator accounts for 6%-14%, and exotic materials accounts for 13%-17%, and said coupling agent is epoxy 18 fat fourth fat; Said no organic initiators is a Potassium Persulphate; Said auxiliary agent is a Vestolen PP 7052, and said nucleator is an azimidobenzene, and said exotic materials is a phosphorous acid ester.
further specify, and each composition weight proportion of the prescription of said blast protection PVDF is that epoxy 18 fat fourth fat account for 47%, and Potassium Persulphate accounts for 8%; Vestolen PP 7052 accounts for 18%, and azimidobenzene accounts for 11%, and phosphorous acid ester accounts for 16%; Can debug according to different ratios according to different demands; Thereby reach different results of use, and epoxy 18 fat fourth fat have the combination of strongthener, Potassium Persulphate and Vestolen PP 7052 help injection molded; It is higher that azimidobenzene has stability; Phosphorous acid ester has to reduce blasts, and the present invention provides a kind of prescription of blast protection PVDF, have strongthener combination, help injection molded, stability is higher and reduce the effect of blasting.
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.
