Problems solved by technology

However, the existing polymer memory glue is not elastic enough. In order to ensure that it will not be pierced by 100mm nails, the spraying thickness must be increased. The spraying thickness is generally 3-8mm, which not only increases the amount of memory glue used, but also improves the use of users. cost, and also increases the weight of the tire and the energy consumption of the vehicle

Abstract

The invention provides an anti-pricking memory adhesive as well as a preparation method and an application thereof. The anti-pricking memory adhesive is prepared from the following components in percentage by weight: 30 to 50 percent of a main body adhesive material; 10%-20% of an elastomer; 25%-45% of a tackifier; 10%-20% of a softener; and 1%-1.5% of an antioxidant. The preparation method comprises the following steps: burdening according to the weight percentage of the glue, and uniformly mixing; heating the mixture to 180-195 DEG C while stirring, then carrying out heat preservation, and continuously stirring for 1-3 hours; and cooling to obtain the glue. The anti-pricking memory adhesive is applied to automobile tires. The anti-pricking memory adhesive disclosed by the invention has high elasticity and adhesive force, and when the anti-pricking memory adhesive is coated on a tire, the pricking resistance and anti-explosion performance of the tire can be improved, and the safety ofthe tire is enhanced. Besides, the automobile tire rubber waste is also adopted, so that the recycling way of the automobile tire rubber waste can be increased, the adhesive force of the rubber material on the inner wall of the tire is improved, and the degumming risk in the use process can be reduced.

Description

technical field [0001] The invention belongs to the technical field of polymer chemical engineering, and relates to a hot-melt pressure-sensitive adhesive, in particular to an anti-jamming memory adhesive and its preparation method and application. Background technique [0002] With the development of society, cars have become a necessary means of transportation for every household. The frequent use of cars also leads to frequent car accidents. According to the survey, 70% of high-speed cars The accident was caused by a tire failure. [0003] At present, in the use of tires, due to the good heat dissipation, softness, comfort and sealing performance of tubeless tires, the interval between use after inflation is long, so cars basically use tubeless tires, and the country of heavy-duty vehicles It is required to gradually promote the application of tubeless tires. But when the tubeless tire is punctured by a sharp object, in a very short period of time, the high-pressure gas...
