Tire sealing composite novel material containing RX-80 tackifying resin

Abstract

The invention discloses a new tire sealing composite material containing RX-80 tackifying resin, which belongs to the technical field of tires, and its formula is characterized by: RX-80 tackifying resin, butadiene rubber, triethylene Composed of tetramine, silica powder, catalpa oil, cuprammonium fiber, naphthol, butadiene rubber particles, and dioctyl ester. The present invention is mainly used in radial vacuum tires, and is a fast self-filling gap (diameter less than or equal to 10mm), non-drying, non-freezing, high reliability, good stability, long-lasting and durable tire sealing composite new material (it can be used in -60°C-112°C environment for long-term use). The product of the present invention contains a variety of high molecular polymers, and its state in the tire is an adhesive state where liquid and solid coexist, and can adhere to the inner wall of the tire stably and evenly for a long time, thereby not affecting the dynamic balance of the wheel. The effect of zero leakage is achieved, which is indeed a revolutionary improvement compared with the prior art.

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 compound material containing RX-80 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
