Manufacturing method of industrial environment-friendly reclaimed rubber

Abstract

The invention provides a manufacturing method of industrial environment-friendly reclaimed rubber, and relates to the technical field of reclaimed rubber production. According to the manufacturing method provided by the invention, by using rap oil seedcakes, peanut oil seedcakes and cotton seed oil seedcakes as a softener, and using modified rosin, terpene resin, lard oil, bone powder and sticky rice to make a tackifier during vulcanization and refining, the produced industrial reclaimed rubber is wear-resisting, flexible, less in pollution, high in density, and free of chemical components, has special light aroma, and is more healthy and environment friendly.

Description

Technical field: [0001] The invention relates to the technical field of reclaimed rubber production, in particular to a method for manufacturing environmentally friendly regenerated rubber for industrial use. Background technique: [0002] In our country, a large number of waste rubber products are treated as waste products and garbage every year, which not only pollutes the environment, but also causes a lot of waste of resources. The recycling of products not only solves the problem of environmental pollution, but also realizes the maximum utilization of resources, energy saving and environmental protection, so the country also strongly advocates it. [0003] Industrial reclaimed rubber requires wear resistance, softness, less pollution, and high density. Conventional reclaimed rubber production rubber powder is generally based on waste tires and other waste rubber products, and a large amount of black coal tar and petroleum extracts are added during the production process...

Problems solved by technology

[0003] Industrial reclaimed rubber requires wear resistance, softness, less pollution, and high density. Conventional reclaimed rubber production rubber powder is generally based on waste tires and other waste rubber products, and a large amount of black coal tar and petroleum extracts are added during the production process. As a softener, the manufactured reclaimed rubber has a very unpleasant pungent smell, and some even contain many carcinogenic chemicals, which pose a serious health threat to both production and users. It can be used for some low-grade rubber products. The invention CN102604151A discloses a kind of rosin or pine tar instead of coal tar or petroleum extract as a softener to solve the above problems. However, the cost of rosin or pine tar is too high, so the produced reclaimed rubber The price is relatively expensive, so it cannot be accepted by the market, and production cannot be popularized
