Abstract
The invention discloses a formula of anti-aging polyvinylidene fluoride. The formula comprises the following components in percentage by weight: 30-70% of modified anti-aging agent, 8%-13% of antioxidant, 7%-14% of auxiliaries, 4%-12% of plasticizing agent and 11%-21% of special materials. The prepared anti-aging polyvinylidene fluoride has the effects of preventing aging due to ultrasonic irradiation, enabling molecular bonds which are of loose structures originally to be tighter and harder, and realizing excellent thermal stability and weathering resistance.
Description
Technical field
the present invention relates to a kind of plastic formula, are specifically related to a kind of prescription of anti-aging 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 have can prevent uviolizing and wear out, make that original loosely organized molecular linkage is more closely hard, the prescription of the new modified PVDF of thermostability and weather resistance excellent results.
technical scheme of the present invention is: a kind of prescription of anti-aging PVDF; Comprise anti-aging agent, oxidation inhibitor, auxiliary agent, softening agent and exotic materials; Each composition weight proportion accounts for 30%-70% for the modification anti-aging agent, and oxidation inhibitor accounts for 8%-13%, and auxiliary agent accounts for 7%-14%; Softening agent accounts for 4%-12%, and exotic materials accounts for 11%-21%.
in preferred embodiment of the present invention, said anti-aging agent is no propyloxy phenyl base.
in preferred embodiment of the present invention, said oxidation inhibitor is the DOS inhibitor.
in preferred embodiment of the present invention, said auxiliary agent is a silicone lubricant.
in preferred embodiment of the present invention, said softening agent is a MALEIC ANHYDRIDE.
in preferred embodiment of the present invention, said exotic materials is a polyoxy ethene.
The prescription of
a kind of anti-aging PVDF of the present invention, have can prevent uviolizing and wear out, make that original loosely organized molecular linkage is more closely hard, thermostability and the good effect of weather resistance.
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 anti-aging PVDF comprises anti-aging agent, oxidation inhibitor, auxiliary agent, softening agent and exotic materials; Each composition weight proportion accounts for 30%-70% for the modification anti-aging agent, and oxidation inhibitor accounts for 8%-13%, and auxiliary agent accounts for 7%-14%; Softening agent accounts for 4%-12%, and exotic materials accounts for 11%-21%, and said anti-aging agent is no propyloxy phenyl base; Said oxidation inhibitor is the DOS inhibitor, and said auxiliary agent is a silicone lubricant, and said softening agent is a MALEIC ANHYDRIDE.
further specify, and each composition weight proportion of the prescription of said anti-aging PVDF is no propyloxy phenyl fiduciary point 52%, and the DOS inhibitor accounts for 11%; Silicone lubricant accounts for 13%; MALEIC ANHYDRIDE accounts for 7%, and polyoxy ethene accounts for 17%, can debug according to different ratios according to different demands; Thereby reach different results of use; Do not have and can prevent uviolizing and wear out that DOS inhibitor and silicone lubricant make that original loosely organized molecular linkage is more closely hard and there is the propyloxy phenyl base, MALEIC ANHYDRIDE and polyoxy ethene have thermostability and weather resistance good; The present invention provides a kind of prescription of anti-aging PVDF, have can prevent uviolizing and wear out, make that original loosely organized molecular linkage is more closely hard, thermostability and the good effect of weather resistance.
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.
