Problems solved by technology

[0003] At present, there is no high-efficiency, applicable, long-term use and non-degumming anti-puncture and leak-proof special safety upgraded polymer synthetic rubber for car tires. Most of the rubber used in tire upgrade services is improved by hot-melt adhesives for shoes or packaging. Although this kind of hot melt adhesive for shoes or packaging can achieve the function of quickly filling the air leak after the car tire is pierced by a sharp object in a short period of time, it may be degummed during the high-speed driving of the car. risk, so that long-term driving safety cannot be guaranteed, and there will still be air leakage after nailing

Abstract

The invention discloses macromolecular synthetic adhesive. The macromolecular synthetic adhesive comprises the following components in percentage by weight: 40 to 48 percent of elastomer, 41.5 to 43 percent of tackifier, 4 to 6 percent of softening agent, 1.5 to 3.2 percent of anti-aging agent and 4.5 to 9 percent of filling agent. The invention further discloses a preparation method of the macromolecular synthetic adhesive. The macromolecular synthetic adhesive has high toughness, high viscosity, high stability, high durability, high tensile strength and special memory performance, a prickedand deformed part of the inner wall of a tyre can automatically recover the memory position when the tyre whose the inner wall is spray-coated with the macromolecular synthetic adhesive is inserted bya sharp object, and the macromolecular synthetic adhesive can rapidly fill a gap formed after the sharp object is pulled out of the tyre, so that the full-sealed space of the tyre still can be maintained and the air leakage condition of the tyre is avoided.

Description

technical field [0001] The invention relates to the field of polymer synthetic glue, in particular to a polymer synthetic glue and a preparation method thereof. Background technique [0002] According to authoritative department statistics, 70% of accidental traffic accidents on domestic highways are caused by automobile tire blowouts, and when automobiles have traffic accidents at a speed of more than 150 km / h, the death rate is close to 100%. Especially small cars are also likely to cause major traffic accidents such as secondary collisions after a high-speed tire blowout. Therefore tire is very important to guaranteeing the driving safety of automobile, and various automobile manufacturers have also released various "explosion-proof tires", but the explosion-proof principle of the current "explosion-proof tire" mainly prevents the tire from being crushed and prevents the tire from being crushed after the tire leaks and loses pressure. The tire comes off the rim, not to p...
