A kind of rubber composition containing organic acid metal salt phenolic resin compound and its preparation method and application

Abstract

The application relates to the technical field of rubber materials, and specifically discloses a rubber composition containing an organic acid metal salt phenolic resin compound, a preparation method and an application thereof. Rubber composition comprises rubber, contains organic acid metal salt phenolic resin compound, methylene donor, sulfur, vulcanization accelerator; Organic acid metal salt phenolic resin compound is made of organic acid metal salt and resorcinol-formaldehyde resin Obtained through a coordination complexation reaction, the structural formula of the organic acid metal salt is (RCOO)m‑M‑(OH)n, m=1 or 2, n=0 or 1, and m+n=2, M is an alkaline earth metal Or a +2-valent transition metal, R is a C2-C30 alkyl group with an unsaturation of 1-10 or R is a C6-C30 aromatic hydrocarbon group with an unsaturation of 3-15. The application improves the interaction between the resin network and the rubber network, and improves the dynamic performance of the rubber compound and the bonding performance of the rubber and the steel wire.

Description

technical field [0001] The present application relates to the technical field of rubber materials, more specifically, it relates to a rubber composition containing organic acid metal salt phenolic resin compound and its preparation method and application. Background technique [0002] With the continuous development of social economy, tire customers put forward higher requirements for the safety and comfort performance of tires during driving. The tire belt layer is the main stress-bearing part of the tire, and its performance has a great Play a decisive role, in the belt layer, the adhesive performance between rubber and frame material is extremely important. [0003] The bonding between the rubber and the skeleton material is the bonding between the flexible rubber and the rigid steel wire surface, which is produced by the physical action of van der Waals force or the chemical action of bonding force. The most commonly used adhesive system is meta-formaldehyde -White adhe...

AI Technical Summary

Problems solved by technology

When the rubber is deformed, the resin network and the rubber network and the Cu x Friction occurs between the S bonding layers, and the heat generation of the rubber increases, and the friction will affect the Cu x The S bonding layer has a destructive effect and reduces the adhesion of the steel wire. At the same time, the resin network cannot be well enriched in Cu under long-term deformation conditions. x S bond layer surface, reducing its effect on Cu x S Protection of the adhesive layer, reduced resistance to aging

[0004] Problems in the traditional bonding system: the resin network and the rubber network are only network interpenetration, the dynamic heat generation of the adhesive is high, the force on the interface between the rubber and the wire is weak, the dynamic adhesion is low, and the rubber Anti-aging performance is not good

Moreover, since the steel wire is rigid and the rubber is flexible, the Cu between the steel wire and the rubber will x S Adhesive layer is easily damaged, affecting the adhesion between rubber and steel wire
