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 sulfurized natural unsaturated phenol modified fatty acid sulfur-containing zinc soap salt and a preparation method thereof.The preparation method comprises the steps that natural unsaturated phenol, unsaturated fatty acid and sulfur are subjected to a sulfuration reaction, then a certain amount of fatty acid is added, the mixture is mixed and then subjected to a saponification reaction with zinc oxide, the sulfurized natural unsaturated phenol modified fatty acid sulfur-containing zinc soap salt is obtained. The zinc soap salt can disperse white carbon black in a vulcanized rubber material, and the molecular structure of the zinc soap salt also contains a reactive sulfur-containing side chain and a phenolic hydroxyl group with relatively high activity, so that the mechanical property, the wet grabbing property and the wear resistance of the rubber material can be effectively improved. The invention further provides application of the zinc soap salt in rubber products such as tire treads, steel wire coating rubber and tire body cords. Natural products which are renewable, green, environment-friendly and rich in resources are used as raw materials, and the sustainable development strategy is met.

Description

technical field [0001] The invention relates to the field of rubber processing aids, in particular to a sulfurized natural unsaturated phenol-modified fatty acid sulfur-containing zinc soap salt and a preparation method and application thereof. Background technique [0002] Silica is a kind of rubber reinforcing filler with great development prospects, 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 relationship between silica and rubber The compatibility of the rubber is poor, the viscosity of a large amount of filling rubber is relatively high, and the processing performance becomes worse with the prolongation of the storage time. Static electricity 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 performance o...
