Abstract
The invention discloses a processing technique for rubber. The processing technique comprises the following steps of: extracting 10-30 percent of natural rubber, 15-20 percent of butadiene styrene rubber, 40-55 percent of regenerated rubber, 10-15 percent of softening agent, 8-10 percent of activating agent and 0.4-0.6 percent of assistant, in terms of mass fraction; mixing the components; desulfurizing the mixture at high temperature and high pressure; and roughly smelting and refining the desulfurized mixture to obtain a finished product. The processing technique disclosed by the invention has the advantages that the processing flow of the rubber is simple and convenient; and the produced products are high in quality and strong in wear resistance.
Description
Technical field
The present invention relates to rubber process, relate in particular to a kind of complete processing of rubber.
Background technology
Under the competition comparison rugged environment of current social since rubber be a kind of recyclable recycling resource, and second development and utilization need to its by every treatment process just can reach effect that new product can reach like this certainly will so that the difficulty of this technique greatly promote, but complete processing how to study a kind of recycled rubber for enterprise has determined the competitive power of the product of enterprise.
Summary of the invention
The complete processing that the purpose of this invention is to provide a kind of rubber.
The technical solution used in the present invention is:
A kind of complete processing of rubber, the natural rubber, the styrene-butadiene rubber(SBR) of 15-20 massfraction, the regenerated rubber of 40-55 massfraction, the tenderizer of 10-15 massfraction, the activator of 8-10 massfraction and the auxiliary agent of 0.4-0.6 massfraction that extract the 10-30 massfraction mix, carry out high temperature, high pressure desulfurization, then slightly refining, refining forms again.
