Abstract

The invention provides a process for producing wear-resistant highly-elastic butyl chloride regenerated rubber. The process comprises the following steps: a, conducting testing, cleaning and impurity removing on a waste butyl chloride rubber raw material; b, feeding the raw material into a pulverizer to be pulverized and granulated to form colloidal particles; c, feeding the colloidal particles, an antioxygen and a plasticizing agent into a desulfurizing device for desulfurization; d, adding a toughening agent, an accelerating agent, a lubricating agent and a fire retarding agent for processing; e, cooling, detecting and packaging a processed product. The process has the benefits that a series of additives of the toughening agent, the accelerating agent, the lubricating agent and the like is added for processing, the elasticity and the abrasion resistance of the product is effectively improved, moreover, heat energy needed in the production process is converted from solar energy, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to a production process of rubber materials, in particular to a process for producing wear-resistant and highly elastic chlorinated butyl regenerated rubber. Background technique [0002] Chlorobutyl rubber has all the inherent characteristics of butyl rubber, but also has a series of advantages such as fast vulcanization speed, co-vulcanization with other rubbers, more heat resistance, and small compression deformation. Therefore, it is widely used in tires, industrial rubber products, building sealing materials and other fields. However, only antioxidants, softeners and plasticizers are added in the traditional production process of chlorobutyl reclaimed rubber. Although the production process is less, the products produced have general wear resistance and poor elasticity, and the desulfurization process is The required heat energy is generally provided by electric heating, which consumes a lot of energy and cannot meet the req...
