Abstract

The invention discloses a macromolecular synthesized memory sizing material which comprises the following raw materials by weight percentage: 41-48% of elastomer, 38-41% of tackifier, 4-6% of softener, 1.5-3.2% of anti-aging agent and 4.5-9% of filler. A pricked part of a tyre sprayed with the macromolecular synthesized memory sizing material under various daily environments can heal automatically; accidents such as air leakage or tyre burst caused by prick of a sharp object can be effectively avoided; especially, the driving safety in a high speed driving state can be ensured to the greatest extent; the service life of the tyre is prolonged under the condition that the original performance of the tyre is not influenced; and various unnecessary troubles such as tyre repairing are reduced.

Description

technical field [0001] The invention belongs to the field of memory materials, and in particular relates to a memory colloid material based on a polymer compound. Background technique [0002] According to statistics and calculations by authoritative departments, 70% of accidental traffic accidents on domestic expressways are caused by car tire blowouts. In addition, when a car is running at a speed of 160 km / h, the fatality rate is close to 100%. Secondly, smaller cars will float when driving at high speed. When a tire blows out, it is more likely to cause a major traffic accident. At present, some manufacturers at home and abroad have also noticed the importance of tires to ensure the safety of automobiles, and have launched "explosion-proof tires" one after another, but the technical content and price of the current design are not satisfactory. For example, the BMW RSC run-flat tire is a product of Continental (Continental) in Germany. The design principle of the run-fla...
