Abstract

An environmentally-friendly composite rubber regenerant is prepared by using plant oil pitch, molasses and plant phenol. A preparation method of the environmentally-friendly composite rubber regenerant comprises the following steps: preparing raw materials, mixing the raw materials at a temperature of 25-75DEG C, uniformly stirring, and naturally cooling to room temperature in order to obtain the environmentally-friendly biomass composite rubber regenerant. Compared with regenerants produced by using petrochemical products comprising coal tar and the like, the regenerant prepared in the invention has the advantages of similar mechanical performances, high quality, low production cost, renewable raw material being inedible oil, and simple production method, and the regenerant prepared in the invention accords with environmental protection requirements, can be used for producing environmentally-friendly regenerated rubber, and provides a cheap and fine rubber regenerant for the production of environmentally-friendly rubber products. The environmentally-friendly regenerated rubber produced by using the environmentally-friendly composite rubber regenerant can be applied to substitute rubber materials in order to save the valuable rubber resource, and can be used to produce various rubber products as a raw material.

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...
