Novel tire sealing composite material containing maleic resin

Abstract

The invention discloses a novel tire sealing composite material containing maleic resin, and belongs to the technical field of tires. The novel tire sealing composite material is characterized by being prepared from maleic resin, polyether rubber, tetrabutyl titanate, PVC micro powder, citronella oil, smashed polyacrylonitrile fibers, a rubber antioxidant 1076, polyether rubber particles and polyether modified silicone oil. The novel tire sealing composite material is mainly applied to radial vacuum tires, and the novel tire sealing composite material can achieve rapid self-mending of notches with the diameters smaller than or equal to 10 mm, cannot be dried up or frozen, is high in reliability, good in stability and durable and can be used for a long time in an environment of 60 DEG C to 112 DEG C. The novel tire sealing composite material contains multiple high-molecular polymers, is in a liquid-solid coexisting sticky state in the tires and can be attached to the inner walls of the tires stably and evenly for a long time, therefore, dynamic balance of wheels is not affected, a zero-leakage effect is achieved, and compared with the prior art, revolutionary improvement is achieved indeed.

Description

technical field [0001] The invention belongs to the technical field of tires and relates to a new self-replenishing material applied to vacuum tire sealing, in particular to a new tire sealing composite material containing maleic acid resin. Background technique [0002] Automobiles and various motor vehicles have become one of the important symbols of modern civilization. During their use, tires are punctured by nails or sharp hard substances on the road surface to cause deflation, which often causes the vehicle to fail to operate normally. The earliest automatic tire sealant was applied in the US military wheeled vehicles in the 1920s and 1930s. The tires of military vehicles were filled with automatic tire sealant. It has a history of 80-90 years. The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1.

Problems solved by technology

The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic balance of the wheel: when a can of automatic tire repair is used After the liquid is removed, 200ml-300ml of liquid remains on the inner bottom of the tire. This liquid makes the wheel run like an eccentric wheel, which not only increases the noise, but also reduces the stability, thus affecting the dynamic balance and belt when the wheel is running. There is a certain degree of traffic safety hazard

2. When the diameter of the tire wound is greater than 6mm, the automatic tire sealant does not work

3. There are also some inflatable tank type automatic tire sealant products, the ingredients of which can only temporarily inflate the flat tire and reduce leakage, until the vehicle is driven to the nearest repair station

4. Some tire sealant products will dry up inside the tire or freeze in cold weather, not only lose the sealing effect, but will damage the inner wall of the tire
