Engineering solid tire intermediate rubber with added fly ash

Abstract

The invention provides engineering solid tire intermediate rubber with added fly ash. The intermediate rubber comprises, by mass, 90-110 parts of natural rubber, 30-50 parts of super wear-resistant furnace black, 20-35 parts of the fly ash, 5-15 parts of aromatic oil, 1-5 parts of zinc oxide, 1-5 parts of stearic acid, 1-5 parts of sulfur and 1-5 parts of an accelerant. By using the fly ash to replace a part of carbon black to serve as one of the production raw materials of the intermediate rubber, the influence on physical and mechanical properties of the rubber material is small; by introducing the material, cost is lowered, and meanwhile product competitiveness is improved; and moreover, by adding a tackifier, a separant, a fame retardant and an anti-pressure agent, all properties of the intermediate rubber are improved, and the problem that when the carbon black is used as one raw material to produce the solid tire intermediate rubber, the physical and mechanical properties of therubber are prone to being influenced is solved.

Description

technical field [0001] The invention relates to the field of rubber manufacturing, in particular to an engineering solid tire intermediate rubber added with fly ash. Background technique [0002] At present, in the manufacture of automobile tires, rubber is used as the intermediate rubber of engineering solid tires, and the general intermediate rubber is generally made of rubber containing carbon black, but when carbon black is used to manufacture rubber, the physical and mechanical properties of rubber will be affected. The performance has a great impact, and it is easy to cause the physical and mechanical properties of the rubber to weaken, which needs to be compensated by other means, thereby increasing the production cost, and the intermediate rubber is located in the middle connecting part of the solid wheel belt, and its physical and mechanical properties have a great influence on it. Big. Therefore, it is particularly important to solve the problem that the physical ...
