Abstract

The invention relates to an environment-friendly high-quality tyre reclaimed rubber manufacturing method, comprising the following steps: selecting waste radial tyre crowns, pulverizing the selected waste radial tyre crowns, screening, and adding composition of rubber powder, vegetable pitch, odourless pine tar oil, starex, activating agent and water while blending, wherein the activating agent is activating agent580; and carrying out banburying after desulfurizing, and carrying out rubber filtering after refining. Since the vegetable pitch, the starex, the odourless pine tar oil and other softeners as well as the activating agent580 are adopted, no pollution exists; especially the activating agent580 substitutes for the activating agen420 with high pollution or the activating agent450 with pollution, desulfuration is more thorough, and the reclaimed rubber has improved quality and no harmful substance and accords with the European Union standards; and since the materials are reasonably selected, and the technologies such as refining, rubber filtering and the like are adopted, the manufacturing of the high-quality reclaimed rubber is realized.

Description

Technical field [0001] The invention relates to a method for manufacturing reclaimed tire rubber, in particular to a method for manufacturing environmentally friendly high-quality reclaimed tire rubber. Background technique [0002] Since 2002, my country has replaced the United States as the world's largest consumer of rubber, consuming 2.8 million tons of rubber annually, of which imports exceed 73%. This fully shows that my country's natural rubber resources are very scarce. Therefore, while my country's rubber industry is vigorously developing new varieties of synthetic rubber and increasing the total output of synthetic rubber, enterprises in various regions continue to pay attention to the recycling of waste tires. Among them, the production of recycled rubber from waste tires is one of the effective ways to make up for the shortage of rubber resources in my country. At present, my country's reclaimed rubber output has reached nearly 2 million tons, ranking first in the wo...
