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.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the drawings, but it is not limited to the embodiments.

[0012] A production method of environmentally friendly biomass composite rubber regenerant. The parameters of each specific embodiment are shown in Table 1. The steps are:

[0013] (1) Material preparation

[0014] The environmentally friendly rubber regenerating agent is composed of three materials: biomass oil, natural resin and plant polyphenols, and their mass percentages are respectively 60-85:10-20:5-30. Among them, the biomass oil is natural rubber seed oil and cottonseed oil. Oil or linseed oil, the source is Yunnan Xishuangbanna Sanhuan Biological Technology Co., Ltd., the natural resin is industrial rosin processed from natural rosin or the by-product of the paper industry wood pulp high oil distillation rosin, the source is Yunnan Jinggu Forest Chemical ( Paper) Co., Ltd., plant polyphenols are pine bark tannin extract from Yunnan Moji...

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 facing people today. In order to meet the ever-increasing material performance requirements, rubber is developing in the direction of high strength, wear resistance, stability and aging resistance, but at the same time it has caused the problem that the waste rubber cannot be naturally degraded for a long time. Because waste rubber cannot be comprehensively utilized, most of it becomes industrial waste, which not only wastes a large amount of available resources, but also causes black pollution that is more difficult to deal with than plastic pollution, which seriously affects the human living environment. The recycling of waste rubber is of great significance to the ...
