Problems solved by technology

On the one hand, because the used filler (reinforcing agent) itself has no cohesiveness and low bonding strength, it only acts as a blockage to the perforation of the tire, and the sealing performance is poor; and the components in the tire sealant are easily dissolved, making the sealing The agent loses the effect of tire repair, and the service life is short
[0005] At the same time, there are many related defects, mainly including: (1) corroding the rim, causing the rim to rust, which has side effects on the tire, making the tire hard and deformed, aging in advance, and affecting the service life of the tire; (2) the repaired gap is small , can only mend small cracks, but cannot mend large holes; (3) cannot mend inner tubes; (4) has limited anti-freeze ability, which will cause gel and freeze when used in severe cold conditions, and cannot recover after freezing, or when the tire temperature is too high A new reaction occurs to make the tire patch ineffective

Abstract

The invention provides a high-efficiency tire sealant. The high-efficiency tire sealant is at least prepared from the following raw materials: modified butadiene styrene rubber, a tackifier, ionic liquid, modified graphene and an antioxidant. According to the high-efficiency tire sealant provided by the invention, the high-efficiency tire sealant is added into a tire through a cycle valve and thenthe tire is inflated again. In the use process of the tire, if sharp materials such as steel nails are punctured into the tire, the sealant provided by the invention can wrap the steel nails, so thatthe situation of air leakage can be avoided; a loophole can be mend in time when the steel nail is taken out at the same time.

Description

technical field [0001] The invention relates to the field of auto parts, and more particularly to the field of car tire maintenance. Background technique [0002] The vacuum tires used by motor vehicles, also known as radial tires, are composed of a layer of steel wire (belt layer) on the periphery of the cord fabric layer, which improves the strength of the tire, has good heat dissipation conditions, and is suitable for high-speed driving; its weakness is that it is afraid of lack of air. When running out of air, the weight increases, the friction with the ground doubles, the temperature of the tire rises sharply, the tire becomes soft, and the strength decreases; the steel wire in the carcass and the ply will also generate heat due to friction, and the overheating state will accelerate the speed of the steel wire. The aging and deformation of the rubber, even internal fracture, and even delamination, bury the root of the tire blowout. Low-speed driving without air will al...
