Abstract

The invention discloses a macromolecule nano selfreparing memory adhesive which consists of the following components in parts by mass: 48-54 parts of butyl rubber, 24-32 parts of polyisobutene, 5-10 parts of a styrene-butadiene copolymer, 1-6 parts of polyacrylate, 0.05-0.15 part of boron trifluoride, 3-9 parts of calcium carbonate, 0.5-1.7 parts of fumed silica and 0.05-0.15 part of carbon black. The macromolecule nano selfreparing memory adhesive disclosed by the invention is capable of rapidly sealing tire holes and is relatively good in malleability and impact resistance, and due to addition of the memory adhesive, the strength of a tackifier and adhesion of tires can be improved; the macromolecule nano selfreparing memory adhesive is capable of repairing air leakage of a tire which is punctured by a nail, a function of leakage prevention can be achieved, relatively good adhesion can be achieved, relatively good ductility and impact resistance can be achieved, and the adhesive can never be peeled off.

Description

technical field [0001] The invention relates to the technical field of tire repair, in particular to a polymer nanometer self-repairing memory glue and a method for using the same. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, whic...
