Heatproof high molecule sealing materials for producing tyres

Abstract

The invention relates to a temperature-resistant polymer sealing material for manufacturing tires, which comprises the following main components and mixture ratio (weight percentage): 38 percent of polythene emulsion, 40 percent of colophony glyceride, 9 percent of expanded nanometer graphite, 2 percent of triguaiacyl phosphite, 5 percent of active silica gel, 1 percent of curing agent, 2 percentof active catalyst and 3 percent of filler. The material is used for the inner sealing material of tubeless air leakage preventing tires. Compared with the sealing elastomer material adopted by the prior art, the main characteristic of the sealing material lies in that the expanded nanometer graphite greatly improves the temperature-resistant stability of the sealing material during the advance of high-speed tires. In addition, component materials are easy to purchase and synthesize and cheaper than international similar products, thereby immensely optimizing the process of anti-leakage anti-prick safety tire inner layer technology.

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...

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
