Abstract

The invention provides an environment-friendly regenerated rubber softener and a preparation method thereof. The softener comprises a main softener and an auxiliary softener which are uniformly mixed, wherein the main softener comprises natural olefin compounds and / or natural phenol compounds, and the auxiliary softener comprises at least one of animal and plant oleic acid, animal and vegetable oil and glycerol. The environment-friendly softener has the following advantages of not containing cancerogenic substances like polycyclic aromatic hydrocarbon (anthracene, naphthalene and the like), and meeting the EU REACH regulations; overcoming the defect of poor physical and mechanical properties of common environment-friendly regenerated rubber; overcoming the difficulty in automatic weighing and conveying due to the viscosity and thickness of traditional softeners; having broad market application prospect and good industrial prospect.

Description

technical field [0001] The invention relates to an environment-friendly softener suitable for reclaimed rubber production and a preparation method thereof, belonging to the field of waste rubber recycling. Background technique [0002] As of the end of 2013, the number of cars in China alone has reached 137 million, ranking second in the world; with that, the number of waste tires has also grown rapidly. How to deal with and recycle these black pollution has become a worldwide problem. [0003] Traditional reclaimed rubber softeners are usually coal tar, aromatic oil and other softeners, but contain naphthalene, anthracene and other condensed aromatic hydrocarbons, which have strong carcinogenicity. Therefore, the EU REACH regulations have listed such chemical products as safe dangerous goods. Products containing such chemicals are prohibited from being exported to countries such as the European Union. The entire rubber product industry (including tires, conveyor belts, et...
