Problems solved by technology

However, there are still many problems in various products on the market. For example, most tire sealants only temporarily stabilize the air pressure, so that the car can drive to the nearest car repair station; some tire sealants will dry up in the tire or Frozen in cold weather will not only lose the sealing effect, but also damage the inner wall of the tire; some tire sealing fluids use various natural fibers or asbestos fibers and chemicals, and these fibers will gradually agglomerate in the tire, losing the sealing effect. And it will wear the inner wall of the tire, and it will make the vehicle vibrate when driving; some are reinforced with natural rubber particles that are harmless to the tire, which can achieve permanent healing with the tire, but the speed of repairing the tire is slow and the anti-freezing effect is poor. It is difficult to meet the needs of market development

Abstract

The invention specifically relates to an auto-inflatable tire repairing liquid and a preparation method thereof, belonging to the technical field of chemical adhesives. The auto-inflatable tire repairing liquid comprises the following raw materials by weight: 15-30 parts of natural latex, 30-50 parts of an antifreezing agent, 0.5-2 parts of a dispersing agent, 0.5-2 parts of an antioxidant, 10-20parts of distilled water, 0.05-1 part of fumed silica, 0.5-3.5 parts of a surfactant, 10-20 parts of nanocrystalline particles and 15-30 parts of hydroxyl butylbenzene latex, wherein the natural latexhas a solid content of 50-70%. According to the tire repairing liquid of the invention, the hydroxyl butylbenzene latex, the natural latex and the nanocrystalline particles are reacted to instantly form a three-dimensional structural network which instantly blocks a punctured tire; the hydroxyl butylbenzene latex and the natural latex are activated by the surfactant and then filled with the fumedsilica so as to form a network structure which inhibits the flowing of colloids, accelerates a curing speed, improves bonding effect and enhances the sealing performance and impermeability of the tire repairing liquid; and the antifreezing agent further enhances the anti-icing ability of the tire repairing liquid.

Description

technical field [0001] The invention relates to the technical field of chemical adhesives, in particular to a self-inflating tire sealant and a preparation method thereof. Background technique [0002] Traditional tire repair requires the vehicle to be stationary, the wheels to be removed, and the inner tube to be removed if there is one. It is very troublesome, a lot of time wasted, and the work efficiency is low. Therefore, the technology of car repair fluid has gradually matured and is recognized by everyone. When the tire is punctured and leaks air, just connect the tire sealant to the tire, press the valve of the tire sealant, and the compressed air will be automatically added to the tire. At the same time, tire sealant will be injected. After the tire pressure is normal, the car can be driven on the road again. Generally speaking, after adding tire sealant to the tire once, as long as the liquid in the tire does not evaporate and leak, even if the tire is punctured a...
