Abstract
The invention discloses an activated fine fluorine rubber powder which comprises the following components in parts by weight: 70-95 parts of primary vulcanized waste fluorine rubber, 1-5 parts of hexafluorobisphenol A as an activating agent, 0.1-3 parts of benzyltriphenylphosphonium chloride, 1-5 parts of magnesium oxide, 1-5 parts of calcium hydroxide and 0.5-2 parts of Brazil wax. The activated fine fluorine rubber powder is mixed into the fluorine rubber, which can achieve property requirements under the conditions of heat and oil resistance and has better property.
Description
Technical field
The present invention relates to a kind of technology of rubber recycling, particularly relate to a kind of activated fine fluorine rubber powder and preparation method thereof.
Background technology
Traditional regenerating waste or used rubber is meant waste old through physical and chemical processes such as pulverizing, heating, treat mechanically, it is reverted to from elastic stage have rubber plasticity and viscosity, can revulcanization.Its essence is: under the physics of heat, oxygen, mechanical effect and sweetening agent etc., chemical comprehensive action, cross-linked rubber network fracture degraded, the existing cross-link bond of fracture position also has the macromole key between the cross-link bond.In recent years; Novel regeneration techniques has also had development to a certain degree; Process for regenerating used rubber both domestic and external has waste old desulfurization regeneration method, and traditional sulfur method has oil process, water/oil method and the domestic HTHP dynamic desulfurization that is widely used in shoddy production.The main drawback of oil process, water/oil method and HTHP dynamic desulfurization is: 1) secondary pollution is more serious, and production efficiency is low, and energy consumption is bigger.2) except that cutting off the crosslinked site of sulfide linkage, also can cause the oxidation and the portion of hot cracking of rubber backbone key.Therefore, strengthen today more and more shorter with the energy day by day in people's environmental consciousness, these traditional methods will progressively be eliminated.In addition, also have chemical regeneration method, ultrasonic regeneration method, radiation regeneration method, shear flow field reaction regeneration method, microorganisms reproduction method etc.The fluorine rubber powder for preparing through above method; On technology, not only exist outside the above-mentioned said shortcoming; It makes to such an extent that fluorine rubber powder is also deposited the problem that hinders this industry development: 1) make the fluorine rubber powder that obtains, the high rerum natura that poor quality can't reach fluorine glue requires to apply in the rugged environment.2) fluorine rubber powder that makes because structure is damaged, makes its physicochemical property have a greatly reduced quality, and can't apply to the sealing member field of high request, can only apply to less demanding fields such as rubber floor covering, has limited its industry development space.3) the fluorine rubber powder physicochemical property that makes of part method can reach requirement, but its processing regenerated cost is high, can only rest on laboratory stage, can't Industry Promotion.
Summary of the invention
One object of the present invention is to provide a kind of activated fine fluorine rubber powder of better performances.
Another object of the present invention is to provide a kind of activated fine fluorine rubber powder preparation method.
For realizing above-mentioned purpose, technical solution of the present invention is:
The present invention is a kind of activated fine fluorine rubber powder; It is made up of the composition of following weight parts; Once vulcanize useless viton 70-95 part, acvator: hexafluoro bisphenol-a 1-5 part, BPP 0.1-3 part, Natural manganese dioxide 1-5 part, calcium hydroxide 1-5 part, brazil wax 0.5-2 part.
The present invention is a kind of preparation method of activated fine fluorine rubber powder; It may further comprise the steps: after will once vulcanizing useless viton and pulverizing through the normal temperature kibbler; Screen the above fine fluorine rubber powder of 250 orders; Add hexafluoro bisphenol-a, BPP and brazil wax high-speed stirring according to the above ratio after 10-15 minute, added Natural manganese dioxide and calcium hydroxide high-speed stirring again 5-10 minute.
After adopting such scheme; Because the present invention is by once the useless viton of sulfuration, hexafluoro bis-phenol, BPP, Natural manganese dioxide, calcium hydroxide, brazil wax etc. constitute; Activated fine fluorine rubber powder of the present invention is sneaked in the viton production of activated fine fluorine rubber powder instead of pure viton.Because its course of processing has adopted being used in combination of mechanical process and chemical method; Reach when both cutting off the crosslinked site of sulfide linkage; Reach the not oxidized and portion of hot cracked assurance of rubber backbone key through the chemical activation method; May ultimately reach the performance requriements under heat-resisting, the oil resistant severe condition, better performances.
Below in conjunction with specific embodiment the present invention is further described.
Embodiment
One, prescription

Embodiment 2:
Once the useless viton of sulfuration is 95 parts, acvator: 5 parts of hexafluoro bisphenol-as, 3 parts of BPPs, 5 parts in Natural manganese dioxide, 5 parts in calcium hydroxide, 2 parts of brazil waxs.
Embodiment 3:
Once the useless viton of sulfuration is 80 parts, acvator: 3 parts of hexafluoro bisphenol-as, 2 parts of BPPs, 3 parts in Natural manganese dioxide, 3 parts in calcium hydroxide, 1 part of brazil wax.
Two, preparation method
The present invention is a kind of preparation method of activated fine fluorine rubber powder; It may further comprise the steps: after will once vulcanizing useless viton and pulverizing through the normal temperature kibbler; Screen the above fine fluorine rubber powder of 250 orders; Add hexafluoro bisphenol-a, BPP and brazil wax high-speed stirring according to the above ratio after 10-15 minute, added Natural manganese dioxide and calcium hydroxide high-speed stirring again 5-10 minute.
Three, performance test
Checking activated fine oxygen powder magistral medicines: 144 parts in viton premix glue, 30 parts of activated fine fluorine rubber powders.
With activated fine fluorine rubber powder mixing viton premix glue, extrusion molding adds sulphur, and the condition that adds sulphur is 170 ℃, 10 minutes; Carry out secondary afterwards and add sulphur, the condition that adds sulphur is 235 ℃, 24 hours.
In order to prove the performance of activated fine fluorine rubber powder mixing fluorine premix glue material of the present invention, it is tested, the result is following:
Pretreating superfine fluororubber powder cross-linked rubber detects data
Through test, prove that it reaches design requirements to the fluoroelastomer glue stock rerum natura through selecting activated fine fluorine rubber powder to sneak into the checking of viton material in the present invention.
The above; Be merely preferred embodiment of the present invention; Scope by prescription of the present invention can form multiple formulations, so can not limit the scope that the present invention implements with this; The equivalence of promptly doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
