Abstract

The invention provides an automatic tire patching agent, which comprises an air pressure agent, an air pressure inhibiting agent, gels, rubber particles, fibers, solvents, additives and nanometer carbon powder. After the automatic tire patching agent provided by the invention is added with the nanometer carbon powder, the bonding characteristic is enhanced, the condensing shrinkage rate of the tire patching agent is reduced, and meanwhile, the friction resistance performance of tires is improved.

Description

technical field [0001] The invention belongs to the field of chemical adhesives, in particular to an automatic tire sealant. Background technique [0002] Car tires are inevitably worn out, punctured, and air leaked during use, and tire repair is an essential technology. [0003] At present, there are two main types of car tire repair agents: [0004] One is a non-inflated liquid repair agent, which is injected into the tire in advance before the car is running. When the car is running, the wheel rolls, and centrifugal force is generated inside the wheel. Under the action of the centrifugal force, the liquid repair agent is evenly distributed inside the tire. When a tire is blown out or a tire is punctured, the liquid repair agent can reach the cavity in a short time to repair and bond to prevent air leakage; Easy to leak again. At the same time, injecting liquid into the tire for a long time will affect the dynamic balance of the car, cause irreparable wear to the tire, ...
