Abstract

The invention provides a waste vulcanized rubber reclaiming agent composition comprising metal complexing compound and aryl sodium sulfonate formaldehyde condensate (general formula: CH2-(-R' SO3Na) 2, wherein R' is aryls comprising phenyl, naphthyl, anthryl and derivative thereof). The composition further comprises stearic acid, diethylene glycol, triethanolamine, white carbon black, natural rubber or synthetic rubber latex and other auxiliary materials. The composition can effectively and fully leads the cross-bond of waste vulcanized rubber to be cracked under the mechanical action at the normal temperature, and leads the waste vulcanized rubber to be restored into reclaimed rubber which can be recycled. The waste vulcanized rubber reclaiming agent composition is applicable to recycling multiple rubbers such as nature rubber, butadiene styrene rubber, butadiene rubber, butadiene acrylonitrile rubber, chloroprene rubber, butyl rubber, ethylene-propylene-diene monomer (EPDM) rubber, halogenated butyl rubber, etc. In the processing process of preparing the reclaimed rubber, the composition generates no waste gas, waste water and waste material. The reclaimed rubber prepared by the composition has the comprehensive physical and mechanical properties reaching to more than 70% of the original waste vulcanized rubber matrix.

Description

Technical field [0001] The invention relates to a waste rubber regenerating agent composition containing organometallic complexes, aryl sulfonate sodium formaldehyde condensates and triethanolamine, etc., in particular to a chemical-mechanical method that can regenerate waste vulcanized rubber at room temperature. Recycling agent composition for reclaimed reclaimed rubber. Background technique [0002] In the production process of reclaimed rubber, regenerating agents play a very important role in improving efficiency, reducing pollution, reducing energy consumption and improving the mechanical and processing properties of reclaimed rubber. Traditional regenerants mainly include diphenyl disulfide, dibenzyl disulfide, dipentyl disulfide, butanethiol, thiophenol and other disulfides and mercaptans. These regenerated active agents need to be equipped with high temperature (180℃~250℃) and long time (2~8 hours) production conditions in the production process of reclaimed rubber, and...
