Problems solved by technology

In order to find a substitute for coal tar, people began to use various non-polluting vegetable oils. However, although the recycled rubber produced by a single vegetable oil is good in environmental protection, it has problems in processing technology, product performance and price, which affects its replacement. Application of Coal Tar in Industrial Production

Abstract

An environment-friendly compound rubber regeneration agent is a product made of the following raw materials in mass percentage: vegetable oil asphalt, molasses and vegetable phenol. The preparation method: prepare raw materials: mix the raw materials at a temperature of 25-75° C., stir evenly, and naturally cool to room temperature to become an environment-friendly biomass composite rubber regenerant product. Compared with regenerants produced by petrochemical products such as coal tar, the product of the present invention has similar mechanical properties, high product quality, low production cost, and the source of raw materials is renewable resources, which is non-edible oil, and the method for processing and production is simple. The product meets the requirements of environmental protection and can be used in the production of environmentally friendly recycled rubber, providing a cheap and high-quality rubber regeneration agent for the production of environmentally friendly rubber products. The application of the environment-friendly regenerated rubber produced by the product of the invention as an alternative rubber material can save precious rubber resources and be used as raw materials for the production of various rubber products.

Description

technical field [0001] The invention relates to a preparation method of a rubber regeneration aid, in particular to an environment-friendly composite rubber regeneration agent and a preparation method thereof. Background technique [0002] If waste rubber is not comprehensively utilized, most of it will become harmful industrial waste, which not only wastes a lot of available resources, but also causes black pollution that is more difficult to deal with than plastic pollution, seriously affecting the living environment of human beings. The regeneration of waste rubber enables the rubber to be reused, saves a lot of rubber resources, and reduces the pollution of waste rubber to the environment. Regenerated rubber refers to waste vulcanized rubber that undergoes physical and chemical processes such as crushing, heating, and mechanical treatment to change it from an elastic state to a plastic and viscous rubber material that can be re-vulcanized. There are many ways to regener...
