Novel adhesion promoting system tire belt ply and preparation method thereof

Abstract

The invention provides a novel adhesion promoting system tire belt ply and a preparation method thereof. The belt ply comprises, in parts by weight, 100 parts of natural rubber, 40-50 parts of carbon black, 8-15 parts of white carbon black, 5-10 parts of zinc oxide, 1-3 parts of cobalt neocaprate, 1-3 parts of a novel adhesion promoter, 2-4 parts of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, 3-6 parts of sulfur, 1.0-1.5 parts of a vulcanization accelerator, 3-5 parts of a methylene donor and 0.1-0.3 parts of a scorch retarder. The preparation method comprises preparation of plasticated rubber, preparation of three-section master batch and final mixing. With the adoption of the belt ply, the using performance of a tire can be improved, the service life of the tire can be prolonged, resources are effectively saved, the cost is reduced, resource waste is reduced, the pollution can be reduced, and the performance can be improved.

Description

technical field [0001] The invention relates to the bonding technology of rubber and metal skeleton materials, in particular to a tire belt layer, in particular to a tire belt layer of a novel adhesion promotion system and a preparation method thereof. Background technique [0002] With the rapid development of social economy and the rapid expansion of the demand for transportation facilities, people's demand for automobile tires is increasing, and the requirements for driving safety are also increasing. However, tires are labor-intensive industries. It is Yuelong Tire's consistent goal to provide operators with an environmentally friendly and good working environment and reduce pollution. Most domestic tire manufacturers still use traditional formula and rubber processing technology. Among them, the traditional adhesion promotion system uses resorcinol, which is easy to produce smoke that is irritating to the eyes and sense of smell, and is harmful to the production environ...

AI Technical Summary

Problems solved by technology

[0003] In the production of tires at home and abroad, due to the design characteristics of the traditional belt layer formula, there are many problems such as crown delamination and crown blowout. In order to solve such problems, various manufacturers are studying solutions. Due to the traditional belt In the production process, the layer formula has strict requirements on process control and is sensitive to temperature control. It often occurs that the extrusion and calendering temperature is too high. This problem has not been completely solved, so there are still problems such as high belt extrusion and calendering temperature, uneven rubber surface, delamination of vulcanized tires, etc. These problems lead to low tire performance, poor safety, short life, etc.

The main reason is that resorcinol is used in the tire belt layer formula, and it is difficult to control the temperature during rubber compounding and extrusion calendering. If the temperature exceeds 105°C, resorcinol is easy to sublime, resulting in frosting on the surface of the belt layer. At the same time, Decomposition smoke is pungent and smoky

This will cause many technical problems in the tire manufacturing process. During the vulcanization process, it is easy to produce shoulder bubbles or crown delamination, which will bring hidden dangers to the tire quality. The pollution in the production process is serious, and the performance of the produced tires is low.
