In the above embodiment of the present invention, the more the amount of water is, the lower the viscosity of the system is, the more stable it is, but the worse the repairing effect is; polyacrylamide or potassium polyacrylate is used as a thickening agent; the ethylene glycol or the glycerol is used as the antifreezing agent, the more the dosage is, the better the antifreezing performance is, the lower the system viscosity is, but the worse the repairing performance is; the more the natural latex is used, the higher the system viscosity is, the poorer the stability is, and the better the repairing effect is; the more the modified styrene-butadiene latex is used, the lower the system viscosity is, the better the stability is and the poorer the repairing effect is; the alkylphenol ethoxylates is used as the emulsifier, the more the dosage is, the higher the system viscosity is, the better the emulsification effect is, the better the stability is, but the worse the repair effect is; the more the amount of alkali (within 3 g), the higher the pH of the system, the better the storage of the latex, and the more stable the system, and at 0.5g, the pH is about 10. KATHON oa LXE fungicide: 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one can simultaneously inhibit bacteria (including gram negative and gram positive bacteria) and fungi (yeasts, molds and the like), and has the advantages of low cost and simple use. Is non-toxic at recommended use concentrations and is free of formaldehyde or formaldehyde emissions; excellent physical and chemical compatibility, no side effect on finished products, low effective active concentration and environmental friendliness. The more the hydroxyethyl hexahydro-s-triazine is, the better the insecticidal and bactericidal effect is. The invention obtains good balance in all aspects by continuously adjusting and optimizing the mixture ratio among the components.
In the invention, the high-ammonia natural latex is natural latex with ammonia content more than 1.2%, which is beneficial to improving the stability of the system and is convenient to store; the modified styrene-butadiene latex is vinyl acetate copolymerization modified styrene-butadiene latex with the grafting ratio of 10% -12%, and can well balance the viscosity of a system, increase the stability and enhance the repairing effect.
The products obtained in the above examples 1 to 6 are respectively products 1 to 6, the appearance of the products is milky liquid, the pH is 10.2 to 10.5, the viscosity at 25 ℃ is 35 to 40mPa.s, and the density is 1.027 to 1.032 g/cm3The content of non-volatile matters at 200 ℃ is 33-35 percent, which all meet the quality requirement of products.
In addition, products 1 to 6 were subjected to heat and cold stability tests: after the heat resistance stability is tested at 90 plus or minus 2 ℃ for 24 hours, the product can be normally used, and after the test of the cold resistance stability at minus 40 plus or minus 2 ℃ for 24 hours, the product can be normally used and meets the quality requirement; in the actual use and detection process, after the tire durability test/the tire high-speed performance test, a product is sprayed out from a puncture part, the air pressure of the pneumatic tire is higher than the specified air pressure, and the tire repairing effect is good.
In the comparative example of the present invention, the latex was only high ammonia natural latex or modified styrene-butadiene latex, but the former had significantly reduced stability, short product life, low practicality, and the latter had low viscosity and poor repairing effect.
The tire repair liquid for the car, provided by the invention, is free of heavy metal components, environment-friendly, good in stability, good in repair effect, long in product storage time, simple in preparation method and low in cost.
The scope of the present invention includes, but is not limited to, the above embodiments, and the present invention is defined by the appended claims, and any alterations, modifications, and improvements that may occur to those skilled in the art are all within the scope of the present invention.
