Abstract

The invention relates to a method for fabricating a polyurethane tire, and discloses a method for fabricating a casting-type polyurethane elastomer tire. The method comprises the following steps: preparing materials, coating, pre-treating a mold, preheating, assembling, casting, primarily hardening and secondarily hardening. By adopting the technology disclosed by the invention, polyurethane can be tightly bonded with a wheel core surface by expanding the molecular polarity; the wheel core surface is coated; the wheel core surface is coated with a material comprising per 1kg of an adhesion agent and 1.2-1.8kg of methyl ethyl ketone (MEK) coating; the relatively great matching is generated between the polyurethane and a wheel core; the bonding strength is improved; the polyurethane and a hardening agent are cast into the mold according to the ratio of 100:(10-100):15 by weight percent in the casting process; the cast mold is hardened twice, so that the polyurethane is full in liquidity in the casting process, and air bubbles are prevented from being formed on the wheel core surface, the adhesion reduction is reduced, and the degumming is avoided.

Description

technical field

[0001] The invention relates to a method for manufacturing a polyurethane tire, in particular to a method for manufacturing a cast elastomer polyurethane tire. Background technique

[0002] Solid tires are a replacement for traditional pneumatic tires used in various industrial vehicles. They are widely used in mines, factories, ports, warehouses and other places with low speed and high load. At present, solid tires are mostly rubber tires. Due to the harsh road conditions in these occasions, the road surface is uneven, the heat generated inside the rubber carcass is high, and the carcass is easy to burst due to the high interior. These will cause early damage to the tire and affect its service life. On the other hand, rubber solid tires use a large amount of carbon black for reinforcement in order to obtain better performance, so that the tires will appear black marks on the road surface during driving and pollute the environment. In some environments such ...
