Rubber production technology

Abstract

The invention discloses a rubber production technology and relates to the field of rubber production. According to the rubber production technology, EPDMs (ethylene propylene diene monomers), carbon black, regenerated rubber, a softening agent, an activating agent and an aid are extracted to be mixed, subjected to high-temperature and high-pressure desulfurization, smelted coarsely and then refined. The rubber production technology has the advantages as follows: the rubber production process is simple and convenient, produced rubber is high in oxidation resistance, corrosion resistance and wear resistance, mutual effects of all components are avoided, the production effectiveness and safety are guaranteed, the temperature range is strictly controlled in a calendering technology, draping of a framework material with the rubber is guaranteed, the density of cords is uniform, and the uniformity of the thickness of the rubber on two sides of the cords is improved.

Description

technical field [0001] The invention belongs to the field of rubber, and more specifically, the invention relates to a rubber production process. Background technique [0002] In the next few years, the shortage of rubber resources will continue to trouble countries all over the world. my country has also formulated a strategy for the development of circular economy, so the reuse of rubber resources is becoming more and more important. With the continuous improvement of international environmental protection awareness, it has been announced internationally that all reclaimed rubber with coal tar as a softener will be rejected for export. At present, in the process of recycling waste tires at home and abroad, there are generally components such as activators, softeners, and catalysts, and they are all produced under high temperature conditions of 200 ° C to 550 ° C and pressures above 2.3 MPa. However, reclaimed rubber manufacturers in my country generally use ordinary rubbe...

Problems solved by technology

However, reclaimed rubber manufacturers in my country generally use ordinary rubber materials for mixed use, so that the product quality cannot be improved.

Due to the use of coal tar as a softener in the production process of reclaimed rubber, there is a strong stench in the production site, which has great pollution to the environment
