The following are examples 1-6, in which the preparation method is the same as above, except that the weight ratio of the specific materials is different, as follows.
Example 1: comprises the following components in percentage by weight: 38 parts of water; 50 parts of ethylene glycol; 0.2 part of poly-p-phenylene terephthamide; 0.7 part of hydroxypropyl methyl cellulose ether; 0.03 part of borax; 3.5 parts of kaolin; 0.6 part of polyisoprene; 0.8 part of sodium dihydrogen phosphate; 0.3 part of sodium nitrite.
Example 2: comprises the following components in percentage by weight: 45 parts of water; 57 parts of ethylene glycol; 0.5 part of poly-p-phenylene terephthamide; 0.2 part of hydroxypropyl methyl cellulose ether; 0.01 part of borax; 1.5 parts of kaolin; 1.3 parts of polyisoprene; 0.4 part of sodium dihydrogen phosphate; 0.05 part of sodium nitrite.

Example 5: comprises the following components in percentage by weight: 40 parts of water; 55 parts of ethylene glycol; 0.31 part of poly-p-phenylene terephthamide; 0.6 part of hydroxypropyl methyl cellulose ether; 0.01-0.02 part of borax; 2.5 parts of kaolin; 0.8 part of polyisoprene; 0.6 part of sodium dihydrogen phosphate; 0.15 part of sodium nitrite.
Example 6: comprises the following components in percentage by weight: 42 parts of water; 54 parts of ethylene glycol; 0.35 part of poly-p-phenylene terephthamide; 0.45 part of hydroxypropyl methyl cellulose ether; 0.01 part of borax; 2.3 parts of kaolin; 0.9 part of polyisoprene; 0.5 part of sodium dihydrogen phosphate; 0.15 part of sodium nitrite.
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; kaolin is used as a thickening agent, so that the cost is low; the ethylene glycol is used as an antifreezing agent, and 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 hydroxypropyl methyl cellulose ether is used as a thickening agent and a binder, and the more the consumption is, the higher the viscosity of the system is, the poorer the stability is, and the better the repairing effect is; 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. Sodium nitrite is used as preservative, and the cost is low. Borax is used as a cross-linking agent, so that the cost is low; the poly-p-phenylene terephthamide and the polyisoprene are used as fillers, so that the property is stable, the cost is low, and the repair strength is high; borax is used as a cross-linking agent, so that the repair strength is high and the cost is low. The invention obtains good balance in all aspects by continuously adjusting and optimizing the mixture ratio among the components.
In the comparison example of the invention, the poly-p-phenylene terephthamide or polyisoprene is deleted from the formula, and the tire repair effect duration is short, the tire repair part is easy to crack after a period of time, while in the comparison example of the poly-isoprene terephthamide deletion, although the tire repair effect duration is long, the strength of the tire repair part is not high, and the tire repair part can be broken again when meeting a large stress again; therefore, the two components need to be combined under a certain proportion to achieve the tire repairing effect with high strength and long duration.
The products obtained in examples 1 to 6 above were products 1 to 6, respectively, which were all off-white liquids having a pH of 10.2 to 10.5, a viscosity of 36 to 40mPa.s at 25 ℃ and a density of 1.03 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 at a puncture part, the air pressure of the pneumatic tire is higher than the specified air pressure, the tire repairing effect is good, the strength after tire repairing is high, the persistence is strong, and the repairing rate is more than 99% (far higher than the repairing rate of less than 90% in the current market). In addition, the tire protective agent for the truck has the advantages of no heavy metal component, environmental friendliness, good stability, good repairing effect, long product storage time, simple preparation method and low 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.
