Problems solved by technology

The so-called "desulfurization" is the process of chemically and physically processing the waste rubber to partially degrade the elastic vulcanizate, destroy the molecular network structure, reduce its elasticity and restore its plasticity and fluidity. There are problems such as high energy consumption, heavy odor in the production process, serious harm to workers' health, and high pressure on environmental protection.

Abstract

The present invention discloses a high-strength recycled rubber, which is prepared from waste rubber powder and an auxiliary material according to a weight ratio of 10:1.5-3, wherein the auxiliary material is prepared from the following raw materials by weight: 25-48 parts of palm oil, 3-12 parts of rosin, 1-3 parts of an activator, 5-10 parts of vinyl bisstearamide, 3-10 parts of tourmaline powder, 1-5 parts of maifanite powder, 2-4 parts of ethylene glycol ethyl ether acetate, 1-3 parts of polyisoprene, and 5-8 parts of dipentene. The invention further discloses a preparation method of the high-strength recycled rubber. According to the present invention, the prepared recycled rubber has characteristics of good tensile strength, good elongation at break and low odor, the density, the ash and other physical properties of the recycled rubber can meet the standard requirements of the scrap recycled rubber, the toxicity is far lower than the standard requirement range so as to improve the performance of the recycled rubber, the high-strength recycled rubber can be used for producing civilian products, belongs to the odorless recycled rubber, and has significant economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of reclaimed rubber production, in particular to a high-strength reclaimed rubber and a preparation method thereof. Background technique [0002] Because of its good elasticity, plasticity, wear resistance and other characteristics, rubber is widely used in industry, national defense and other fields. It has long been an important strategic material of the country and occupies an important position in national economic and social development. my country is a big country of rubber consumption, with consumption accounting for 28% of the world's total, but rubber resources only account for 12.2% of the world's total. More than 80% of natural rubber and 46% of synthetic rubber are imported each year, which has been below the international safety line for five consecutive years. 30%, becoming the fourth largest shortage of strategic materials after oil. At the same time, my country is a country that produces the ...
