Problems solved by technology

[0002] In the prior art, wheelchairs generally use rubber tires, which are generally pneumatic tires. In the case of uneven road surfaces, the inside of the rubber carcass tends to generate high heat, thus causing the tires to burst.
Now there are some rubber solid tires on the market, and these rubber solid tires often add carbon black and other materials to their raw materials in order to increase their strength, so that black marks will appear on the road surface when the tires are running, which in turn will cause environmental pollution, etc.
[0003] To sum up, traditional rubber tires have short service life, low safety, and poor wear resistance, and there are a large number of quality defects

Abstract

The invention discloses a raw material formula of a PU wheel, a raw material production process and a processing method thereof. The raw material formula of the PU wheel comprises a component A and acomponent B, wherein the component A is prepared from the following raw materials in parts by weight: 60-80 parts of polyester polyol, 0.1-0.2 part of foam stabilizer, 5-10 parts of foaming agent, 1.3-5 parts of surfactant, 15-20 parts of chain extender, 0.15-0.3 part of composite catalyst, 5-10 parts of aramid pulp, 3-5 parts of curing agent and 6-12 parts of antistatic agent. The component B isprepared from the following raw materials in parts by weight: 20-50 parts of polyester polyol, 5-30 parts of polyether polyol and 80-90 parts of isocyanate. The PU wheel produced by the formula has elasticity, is excellent in damping effect, strong in road holding force, low in possibility of slippage, high in abrasion resistance, high in tearing strength, high in safety and long in service life.
