A kind of airtight adhesive used for anti-puncture of tire and preparation method thereof

Abstract

The invention discloses an airtight adhesive used for tire puncture prevention and a preparation method thereof, belonging to the technical field of tire manufacture and repair. The airtight rubber of the present invention is based on chloroprene rubber, natural rubber, bamboo powder, tackifying resin RX-80, high ammonia natural latex, KN4006 naphthenic rubber oil, rosin, zinc oxide, modified pineapple leaf fiber, accelerator DETU , silane coupling agent Si‑563, dispersant WB212, stearic acid SA, polyphenyl polymethylene polyisocyanate, antioxidant RD, sodium persulfate, biphenyl yellow G as raw materials. The present invention adopts high-ammonia latex, chloroprene rubber with good airtightness and natural rubber with good processability as the mixing system, and the properties of the colloids complement each other. At the same time, the modified pineapple leaf fiber is added to improve the rubber layer and the mouth glue during molding. The viscosity between the materials improves the tensile and tear strength of the rubber, and the various compounding agents cooperate with each other to jointly improve the bonding and repair performance of the product.

Description

A kind of airtight rubber for tire puncture prevention and preparation method thereof technical field The invention belongs to tire manufacture and repair technical field, be specifically related to a kind of airtight rubber for tire puncture prevention and its preparation method. Background technique [0002] With the growth of China's economic strength, the automobile industry has developed rapidly, and automobile transportation has become an indispensable and important Tools directly promote the industrial development, technological innovation and progress of the tire industry. Tires as an important support for transportation and strategic resources, which are highly valued by countries. Tire leakage has caused great harm to the development of the national economy and the personal safety of the people. Affected, tire repair operation is necessary. Tire puncture-resistant airtight compounds play a vital role. [0003] The tire is made of rubber as the base materia...

AI Technical Summary

Problems solved by technology

However, there are obvious defects that the gap of the rubber strip is easily leaked; the cold patch is easy to age and fall off; the angle of mushroom nail repair is limited to less than 15 degrees; the fire repair is the most thorough and requires less, but this method requires professionalism. technical and formal equipment

Careless handling can cause permanent damage to the tire

[0004] The use of tire sealant is also a common method. Tire sealant is a chemical material containing a variety of polymers. It is widely used in rubber tires of various electric vehicles, motorcycles and small and medium-sized cars. Traditional tire sealants contain sulfuric acid. Copper, showing blue color, has certain heavy metal poisoning and corrosiveness, and the effect of tire repair needs to be improved
