8%~30%, dispersing agent 0.1%~8%, liquid antioxidant 14%~78%, processing aid 25%~70%.
Above-mentioned epoxy glue is SBR, EPDM, EVA, butadiene rubber wherein any two kinds of mixture.
Aforesaid liquid antioxidant is the mixture of one or more of liquid amine antioxidants, liquid phenolic antioxidant,
It better disperses antioxidant in process, improves the antioxygen property of master batch.
Above-mentioned dispersing agent is the mixing of one or more of polyethylene wax, polypentaerythritol stearate, zinc stearate
Object, above-mentioned processing aid are the mixtures of one or more of white carbon black, carbon black, diatomite, calcium carbonate.Dispersing agent can make
Each rapidoprint with raw rubber be kneaded in be uniformly dispersed, the addition of processing aid can reduce production cost.
The utility model has the advantages that compared with prior art, the beneficial effects of the present invention are:
The production operation of master batch of the present invention is easy, contains liquid antioxidant in anti-oxidant predispersed masterbatch of the invention, benefit
In the dispersibility of antioxidant, and avoid powder antioxidant bring dust harzard.It solves antioxidant and disperses uneven, dust
Between pollution and each material the shortcomings that poor compatibility, the anti-oxidant predispersed masterbatch antioxygenic property of production is good, good dispersion, adds
Work is excellent.
