Abstract

The invention specifically relates to a polyurethane antiskid tire and a preparation method thereof, belonging to the technical field of polyurethane products. The polyurethane antiskid tire is characterized by comprising a component A and a component B, wherein the component A comprises, by weight, 40-60 parts of polyether polyol DEP-330G, 40-80 parts of polyether polyol DMD-3000, 0.1-0.6 part ofwater, 0.5-0.9 part of a foam stabilizer, 0.3-0.5 part of an amine catalyst, 1-3 parts of a cross-linking agent, 5-8 parts of a chain extender and 1-2 parts of color paste; and the component B comprises, by weight, 20-35 parts of a modified black material. Through compounding effect of the above components, the prepared polyurethane antiskid tire of the invention has good antiskid performance andimpact resistance; and the preparation method is simple in processing technology and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of polyurethane products, and in particular relates to a polyurethane anti-skid tire and a preparation method thereof. Background technique [0002] During the use of rubber tires, materials such as polycyclic aromatic hydrocarbons and carbon black in the tread will be released into the air and soil, seriously polluting the environment. It is difficult to recycle waste tires and consume more manpower, financial and material resources. [0003] Polyurethane materials are easier to recycle than rubber. Recycling by physical methods can be used to produce polyurethane products with low performance requirements. Recycling by chemical methods can obtain pure raw material monomers, such as polyols, isocyanates, and amines. The existing polyurethane tires have problems such as poor skid resistance and impact resistance. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the purpose o...
