High molecule sealing materials for manufacturing tyres

Abstract

The invention relates to a macromolecular sealing material for manufacturing a tire. The main compositions in weight percentage of the macromolecular sealing material for manufacturing the tire are 28 percent of iso-acrylic acid ethanol, 40 percent of terpene phenol resin, 10 percent of SEBS (elastomer), 9 percent of expanded nano graphite, 2 percent of triguaiacyl phosphate, 5 percent of activated silica gel, 1 percent of curing agent, 2 percent of activate catalyst and 3 percent of filler. Compared with an elastomer adopted in the prior art, the inner layer sealing material for the leakproof tire without an inner tube has the maincharacteristics that the temperature-resistant stability of the sealing material during the travel process of the high-speed tire is greatly improved due to adoption of the expanded nano graphite; simultaneously both purchase and synthesis of various composite materials are simple and convenient and the cost is lower than that of international similar products; and simultaneously the optimization of the inner layer technical matters of the leakproof and prick-proof safety tire is greatly supported.

Description

technical field [0001] The invention relates to new polymer synthesis materials, in particular to a high-temperature-resistant polymer sealing material used for manufacturing tires. Background technique [0002] Since the 1960s, with the use of radial tubeless tires, international professional tire research institutions have been researching a leak-proof and anti-puncture safety tire that is acceptable in the market in terms of cost and technology. . In the 1980s, the main technology was embodied in the technical method of filling the tire with liquid glue. As the tire rotated, it was evenly distributed on the inner surface of the tire. Because of seriously affecting the various technical performances of tires, it has not been accepted by the market. In the 1990s, a major technological breakthrough in this field was the use of isoprene rubber or silicone rubber to spray a layer of 2-3mm solid viscose on the inner layer of the tire. The use of active memory to automaticall...

AI Technical Summary

Problems solved by technology

[0003] 1) The materials such as isoprene rubber used are expensive; 2) During the high-speed operation of the inner tube coating, the local deformation of the coating due to high temperature will seriously affect the tire dynamic balance; 3) The activity of the inner tube coating is anti-aging No practical technological breakthrough can be achieved in performance; 4) Because the raw materials used are dependent on imports, cost and industrialization development are factors restricting promotion
