Problems solved by technology

[0005] In view of the fact that the existing fatty acid zinc soap salt does not react with rubber molecules, it only forms a strong polar force between the polar functional group and the rubber molecules to play an internal plasticizing effect, if it is not well dissolved in the rubber It will also lead to a decline in the performance of rubber products and reduce the service life of rubber products

Abstract

The invention discloses a sulfur-containing zinc soap of sulfurized natural unsaturated phenol-modified fatty acid and a preparation method thereof. The zinc oxide is subjected to a saponification reaction to obtain the sulfur-containing zinc soap of the sulfurized natural unsaturated phenol-modified fatty acid. The zinc soap salt of the invention can disperse white carbon black in the vulcanized rubber compound, and its molecular structure also contains reactive sulfur-containing side chains and phenolic hydroxyl groups with high activity, which can effectively improve the mechanical properties of the compound, Wet grip and abrasion resistance. The present invention also proposes to use the zinc soap salt in rubber products such as tire tread, steel wire covering and carcass cord. The invention uses renewable, green and environmentally friendly natural products as raw materials, and conforms to the sustainable development strategy.

Description

technical field [0001] The invention relates to the field of rubber processing aids, in particular to a sulfur-containing zinc soap of vulcanized natural unsaturated phenol-modified fatty acid and a preparation method and application thereof. Background technique [0002] Silica is a promising rubber reinforcing filler second only to carbon black, but the surface of silica contains a large number of hydroxyl groups, which leads to its high acidity, hygroscopicity and hydrophilicity; The compatibility of the rubber compound is poor, the viscosity of a large amount of filling compound is large, and the processing performance deteriorates with the extension of storage time. Static accumulation [Yan Hexiang et al., Rubber Industry, 2004, 51(6):376-378.]. Therefore, in the processing of various rubbers, it is necessary to add some processing aids to improve the processing properties of the rubber compound. [0003] Currently commonly used processing aids include fatty acid deri...
