Abstract

The invention discloses an environment-friendly rubber regenerating process. The environment-friendly rubber regenerating process comprises the following steps: first, selecting waste rubber meeting specifications, and performing the steps of cleaning, removing impurities and picking; then, crushing by utilizing a crushing machine; placing the broken rubber in a reaction kettle; adding a de-sulphurizing agent, an anti-oxidant and a softening agent into the reaction kettle; after raw materials react fully, cooling the reacted material in a cooling tower; pressing the cooled rubber through a refining mill and an open mill of rubber pressurizing equipment, discharging pieces to produce a regenerated rubber finished product. Compared with the prior art, the environment-friendly rubber regenerating process has the following advantages that a linear molecular chain cannot be broken; the material taking and operating are both safe; environment-friendly civilized production is realized; the quality of a rubber material is improved; the environment pollution is avoided; the production cost is reduced.

Description

technical field [0001] The invention relates to an environment-friendly rubber regeneration process. Background technique [0002] With the rapid development of my country's national economy, natural synthetic rubber can no longer meet the needs of the market. The rubber recycling industry is in line with my country's national conditions, and the comprehensive utilization of waste rubber is beneficial to the country and the people, because my country is a big consumer of rubber resources, and the drum type is one of the countries where rubber resources are very scarce. The production of recycled rubber can make up for the shortage of rubber resources in the country, and can make rubber recyclable. The development of recycled rubber will surely become the main force in my country's rubber development. The biggest problem facing recycled rubber at present is high energy consumption and low output, which is not conducive to industrial production. [0003] Therefore, the gree...
