Self complement agent for automatically inflating, repairing tyre and extinguishing fire, and method of producing the same

Abstract

The invention discloses a self complement agent which automatically charges air, repairs tires and puts out a fire as well as a preparation method thereof. The self complement agent is formulated by materials including concentrated natural rubber latex, a flame retardant, a foaming agent, a plasticizer, a polymerization inhibitor, a stabilizer, an emulsifier, an organic solvent, distilled water, an antifreeze and the like according to a certain method, and integrates the functions of tire repairing, air charging and fire killing as a whole; the self complement agent does not have toxic and side effects, not only protects the tires, but also is economic and environment protective; the application of the self complement agent is broad; and the preparation method of the self complement agent is simple, easy to be carried out and the economic cost is low, thus leading the self complement agent to have excellent market popularization value.

Description

technical field [0001] The invention relates to a chemical composition and a preparation method thereof, in particular to a chemical composition used for automatic inflation and leakage repair of rubber tires, and a chemical composition used for fire extinguishing and a preparation method thereof. Background technique [0002] Tires are an indispensable and important part of vehicles. Most of the tires used at this stage are pneumatic tires. Pneumatic tires have irreplaceable advantages in use, but they also have their own limitations. Since pneumatic tires are made of rubber, they are easily punctured by sharp objects and deflated during driving. If this happens, you often have to stop and dismantle the tires, and then replace the spare tires or repair the damaged inner tubes. It brings considerable inconvenience to the driver, especially in severe weather conditions such as wind, rain, snow and fog. What's more, when the car is running at high speed, it may cause serious s...

Problems solved by technology

This kind of glue can play a certain role, but it also has irreparable defects: this kind of glue completely uses its own strong viscosity to complete the repair of the tire, and will completely bond the inner and outer tires of the tire while repairing the breach, making it impossible to separate , which will lead to expensive tires that cannot be reused, resulting in greater economic losses; at the same time, the glue is also highly corrosive, and will corrode the valve core and wheel net after use, and will evaporate into a gaseous state when heated and lose its repairing ability; In addition, the glue has poor antifreeze performance and will freeze when it is cold, which seriously affects the dynamic balance of the car when driving.

[0004] There is also a kind of mixed rubber product that is combined with a binder and a filler. As the application number is 97118301.5, a Chinese patent application discloses a tire all-round self-replenishing anti-leakage agent, which includes polyvinyl alcohol 1.8-3.9%, ethylene glycol Alcohol 20-37%, rubber particles 0.2-2%, paper fiber 0.2-0.7%, iron red 0.2-1%, wollastonite powder 2-2.8%, calcium carbonate powder 1-2.6%, carboxymethyl cellulose 0.5- 0.9%, copper sulfate 0.1-0.5%, calcium chloride 2-3.5%, benzoic acid (sodium) 0.1-0.9% and water 50-70%, although this self-healing agent has reached the effect of automatic tire repair to a certain extent purpose, but there are still many deficiencies in the process of use: first, the effective use time of the tire cannot be extended, and the service life of the tire using this product is about 6 months; second, the product is alkaline, which is easy to make the tires inside The metal parts such as the valve core and the wheel net are corroded, so that the water and other raw materials cannot be well combined, thereby reducing the quality of the product and failing to achieve a better self-replenishing effect

[0005] Application number is that the Chinese patent of 02133805.1 also discloses a kind of tire self-healing agent, by weight ratio, by the polyvinyl alcohol of 6%~12%, the sodium benzoate of 0.5%~1.5%, the ethylene glycol of 15%~30% , 0.8%~1.4% sodium nitrite, 2%~8% N-phenyl-a-naphthylamine, 10%~16% filler composed of rubber particles, talcum powder, calcium carbonate powder and polypropylene fiber, 50% to 65% of water. Although this self-replenishing agent has the advantages of quick leakage repair, good stability, and anti-aging, it is extremely corrosive and has a bad smell. It has the function of self-inflating, no plasticizer is added, it has disadvantages such as poor toughness, no flame retardant is added, and it does not have the effect of fire extinguishing
