All-steel radial tire belt compound rubber composition and production method thereof

Abstract

The invention relates to the technical field of rubber, in particular to an all-steel radial tire belt compound rubber composition, which is characterized by comprising the following materials in parts by weight on the basis of 100 parts by weight of alkadiene elastomer: 30-60 parts of carbon black, 5-15 parts of white carbon black, 3-10 parts of methylene donor, 1-3 parts of environment-friendly resin, 4-10 parts of sulfur, 1-2 parts of cobalt salt and 1-2 parts of accelerant, wherein the environment-friendly resin is obtained from R modified m-phenol diamine, and R mainly represents styrene; and the alkadiene elastomer is selected as one or a mixture of smoke sheet rubber, standard rubber and synthetic polyisoprene rubber. The all-steel radial tire belt compound rubber composition is of great help to reduction of the production cost of the compound; and on the premise of meeting the basic performance such as strength, elongation and resilience of the belt compound, the performances such as an adhesive force between the compound and a steel tire cord and the adhesive force between boundaries of rubber and a steel wire at the later stage of use can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an all-steel radial tire belt rubber composition and a production method thereof. Background technique [0002] As we all know, in the production and manufacturing process of all-steel radial tires, the bonding between the adhesive rubber material and the copper-plated steel wire skeleton material is extremely important. most important part of the system. The traditional m-formula adhesive system uses resorcinol and hexamethoxymelamine in combination. Since resorcinol is easy to sublimate, smoke and bloom under the mixing and processing conditions, it is harmful to production, environmental protection and Workers' health poses many hazards. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a kind of all-steel radial tire belt rubber composition, which improves the "smoking" a...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a kind of all-steel radial tire belt rubber composition, which improves the "smoking" and gumming caused by the use of resorcinol products in the past production. The problem of material "blooming" and low material utilization rate is of great benefit to environmental protection and human health, and at the same time it is of great help to reduce the production cost of the rubber material; Under the premise of the basic properties such as rate and rebound, it can also ensure the adhesion between the rubber material and the steel curtain, and the adhesion between the rubber and the steel wire interface in the later stage of use.
