Environmentally-friendly biomass compound rubber regenerant and preparation method thereof

Abstract

The invention provides an environmentally-friendly biomass compound rubber regenerant. The regenerant is prepared from the following raw materials in mass percentage: 60-85% of bio-oil, 10-20% of natural resin and 5-30% of plant polyphenol. The preparation method of the regenerant comprises the following steps: (1) heating the bio-oil to 60-85 DEG C; (2) respectively adding the natural resins andthe plant polyphenol to the bio-oil and evenly mixing; and (3) naturally cooling the evenly mixed product to room temperature to finally obtain the environmentally-friendly biomass compound rubber regenerant product. In the invention, the bio-oil, the natural resins and the plant polyphenol which are extracted from plants are taken as raw materials, and the raw materials are renewable materials, which realizes maximum resource utilization and reduces dependence on petrochemical resource so as to achieve the purpose of green production of reclaimed rubber. The regenerant has the advantages of good rubber regeneration effect, high product quality, low production cost and no pollution and nuisance during the production process. The environmentally-friendly reclaimed rubber produced by the regenerant can be widely applied to various rubber products and can replace rubber materials, thus saving rubber resources.

Description

technical field [0001] The invention relates to a rubber regeneration aid and a preparation method thereof, in particular to an environment-friendly biomass composite rubber regeneration agent and a preparation method thereof. Background technique [0002] The disposal of waste rubber is one of the serious problems that people face today. In order to meet the ever-increasing requirements of material properties, rubber is developing towards high strength, wear resistance, stability and aging resistance, but at the same time it causes the problem that the discarded rubber cannot be naturally degraded for a long time. Since waste rubber cannot be comprehensively utilized, most of it becomes 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 recycling of waste rubber is of great significance to the protect...

Problems solved by technology

At present, the regenerants used in the production of regenerated rubber are mainly coal tar and various chemical substances. Coal tar and chemical substances have great environmental pollution in the production process of regenerated rubber, and are used in the process of processing and producing rubber products. A harmful substance that is not conducive to environmental protection, which does not meet the environmental protection technical requirements of the rubber industry at home and abroad for recycled rubber, and limits the application range of recycled rubber in rubber products.
