Novel tire sealing composite material containing 601 tackifying resin

Abstract

The invention discloses a novel tire sealing composite material containing 601 tackifying resin and belongs to the technical field of tires. The formula is characterized by being composed of the 601 tackifying resin, epichlorohydrin rubber, a cross-linking agent BIPB (Bi(butylperoxyisopropyl)benzene), chlorinated polyethylene micro-powder, pine oil, crushed artificial protein fibers, a rubber antioxidant crotonaldehyde, epichlorohydrin rubber particles and epoxy soybean oil. The novel tire sealing composite material is mainly applied to a meridian vacuum tire and is the novel tire sealing composite material which can be used for rapidly self-repairing a notch (with the diameter smaller than or equal to 10mm), is not dried and frozen, is high in reliability and good in stability and is durable; the novel tire sealing composite material can be used in an environment at a temperature ranging from -60 DEG C to 108 DEG C for a long period. The product disclosed by the invention contains a plurality of types of macromolecular polymers; the state of the material in the tire is a sticky state with liquid and solid and can be stably and uniformly stuck on an inner wall of the tire for a long period, so that the dynamic balance of wheels is not influenced and a zero-leakage effect is also realized; compared with the prior art, the novel tire sealing composite material is definitely innovative improvement.

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 601 tackifying 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
