Problems solved by technology

These four types of products all have limitations: Type 1 and Type 2 products must be stable in alkaline systems, and Type 1 products are more alkaline, and because most of the current tire hubs are made of aluminum alloy Alkaline products have a corrosive effect on it, and the stronger the alkalinity, the more serious the corrosion will eventually lead to the scrapping of the wheel hub of the tire; another defect of these two types of products is that after the product is added to the tire, due to the reaction with aluminum, the The pH value of the system, thereby curing the product, affecting the balance of the car and endangering driving safety
In the third category of products, the inflatable component is a flammable and explosive gas, which has great safety hazards during storage and use. At the same time, due to the low pressure of liquefied petroleum gas, it cannot be vaporized in winter in the north, so it cannot be used.
In the fourth category of products, the inflatable components are Freon-based gases, which will be restricted for environmental protection reasons, and the vapor pressure of Freon gases is high. Taking F12 as an example, the vapor pressure at 50°C reaches 1.7MPa, while The national standard pressure resistance of aerosol tinplate cans is 1.2MPa, so there is a possibility of explosion when stored in the compartment in summer

Abstract

The invention relates to a tire inflation leak-repairing agent which adopts a water-based acrylate adhesive as the main leak-repairing agent, and tetrafluoroethane and hexafluoropropane as a main air inflation agent. The tire inflation leak-repairing agent comprise a liquid component (1) and a gas component (2) by mass percentage, wherein the liquid component (1) comprises 17%-63% of the water-based acrylate adhesive, 2%-23% of C1-C5 alcohol, 1%-28% of glycol ether, 1%-9% of a nonionic surfactant, 0.02%-0.1% of nipalgin, and the balance of water; the gas component (2) can be a mixture of the following constituents: 15%-100% of the tetrafluoroethane, 0%-80% of the hexafluoropropane, and 0%-30% of propane, butane or propane and butane. According to the invention, an aerosol cans is adopted to pack a product, and the mass ratio of the liquid component to the gas component is 1 to 1-3.

Description

technical field [0001] The invention relates to a new type of environment-friendly automobile chemical which can immediately repair leaks and inflate vehicle tires. Background technique [0002] With the rapid growth of automobile production and sales in recent years, in order to ensure driving safety and travel convenience, reduce the time and energy spent on disassembly, replacement and repair of vehicles after tires are punctured, and avoid road congestion, a variety of tires have been produced. Inflatable leak trap. At present, there are mainly the following types of tire inflatable leak trapping agents on the market: 1. The main leak trapping agent is mainly natural rubber, supplemented by ammonia water as a stabilizer; 2. The leak trapping main agent is made of polyvinylpyrrolidone, cellulose or polyurethane glue.
