Abstract

The invention belongs to the technical field of tire manufacturing, and particularly relates to composite polyurethane tread rubber and a preparation method thereof. The composite polyurethane tread rubber is obtained through mixing of the following raw materials of mixing type polyurethane rubber, traditional rubber, unsaturated carboxylic acid, metallic oxide, superoxide, an assistant crosslinker and a plasticizer. The composite polyurethane tread rubber provided by the invention can effectively solve the technical defects that the mechanical strength and the anti-fatigue strength in a traditional polyurethane tire technique can sharply decline along with a high temperature and high speed driving condition, a carcass is prone to occurring deformation or tire bursting, a binding part is liable to fall off, the curing speeds of polyurethane and traditional rubber are not matched in a sulfur vulcanization system, and thus undervulcanization and incompatibility exist when two rubber areused simultaneously.

Description

technical field

[0001] The invention belongs to the technical field of tire manufacture, and in particular relates to a composite polyurethane tread rubber and a preparation method thereof. Background technique

[0002] With the rise of the global low-carbon economy, "green manufacturing" has become one of the important strategic guidelines for the sustainable development of China's rubber industry. Increasing product structure adjustment, vigorously developing safe, energy-saving and environmentally friendly raw materials, and developing new products are the basis of "green manufacturing". Along with the development of the automobile industry, tire technology and theory are constantly improving and improving. Although the current pneumatic radial tires have good dynamic performance, such as small deformation during driving, low heat generation, excellent elasticity, and are suitable for high-speed driving. etc., but at the same time, there are disadvantages such as poor we...
