Fourth nitrile reclaimed rubber is to produce raw material of mainstream of products of rubber of all sorts of oil resistant, wear-resisting, can use alone already also can use the product with preparation higher performance with other balata. These rubber products will be ceaseless in working process heat build-up, the fourth nitrile sizing material that with the hot solid such as colophony of alkyl phenolic aldehyde, epoxy resin sexual colophony regards vulcanizing agent as vulcanization has good heat-resisting ageing sex, chemistry stability and be able to bear or endure bend flexibility can. In actual production, reclaimed rubber of use man nitrile or fourth nitrile balata / when fourth nitrile reclaimed rubber produces balata product with glue, theoretic can use colophony to undertake vulcanization. When HYL16Y12YEEYC of fourth nitrile reclaimed rubber uses colophony vulcanization, place needs to have with colophony more lively luscious base round, in vulcanization process can with balata macromolecule medium lively base group happening action, make the cross-linking structure between macromolecule through colophony element.

The colophony vulcanizing agent with fourth nitrile commonly used balata is colophony of alkyl phenolic aldehyde; Use vulcanizing system of colophony of alkyl phenolic aldehyde, ordinary control is in vulcanizing agent dosage between 30-40 portion, vulcanization temperature control is between 150-160 ℃ , vulcanization time control is controlled in 2 hours. Fourth nitrile reclaimed rubber can regard referenced data as this data, adjust colophony dosage and vulcanization requirement appropriately. In actual production, the colophony with molecular too large amount is unfavorable use at vulcanization of fourth nitrile reclaimed rubber, in order to shun effect of cross-linking of reclaimed rubber of fourth nitrile of vulcanizing agent influence and physical function. The ester of much surprise cyanic acid of portion of right amount use 1-5, multivariate alcohol much more luscious base round compound can increase density of cross-linking of glue of fourth nitrile vulcanization. Use as in recipe of vulcanization of fourth nitrile reclaimed rubber the colophony dosage of vulcanizing agent shoulds not be too big, dosage can bring about partial colophony to cannot produce vulcanization effect with fourth nitrile sizing material too much, rise to add model effect only, affect performance of cross-linking effect and machinery of vulcanization glue physics, extend intensity to drop surely for instance, permanent be out of shape increase etc. Colophony vulcanization speed relatively other vulcanizing system is slow, when determining condition of vulcanization of colophony of fourth nitrile reclaimed rubber, divide outside extending vulcanization time, still need to raise vulcanization temperature appropriately. Right amount add add much amine compound, if much surprise is cyanic acid ester, multivariate alcohol much more luscious base round compound, dosage is 1-5 portion, can raise rate of cross-linking of glue of vulcanization of fourth nitrile reclaimed rubber. Brimstone vulcanization still can be used when producing balata product for main raw material with fourth nitrile reclaimed rubber, cross oxide vulcanization to wait, later stage is small make up will continue to share pertinent question with you.
