Problems solved by technology

Although this type of deproteinized natural rubber latex can effectively improve the allergic reaction to the human body, it does not eliminate or reduce the strong irritating odor produced when used as a self-supplement
At present, as a pH regulator of natural rubber latex, it is trying to use reagents other than ammonia, but in practical applications, it is difficult to sufficiently ensure the stability of natural rubber latex in self-replenishing agents

Embodiment Construction

[0031] The present invention is described in detail below in conjunction with embodiment.

[0032] The vehicle tire self-healing agent is prepared from the following raw materials in weight percentage,

[0033] Butyl latex 45~70%

[0034] Sodium salicylate 0.5~0.9%

[0035] Pingping plus O 0.2~0.5%

[0036] Composite antifreeze 15-30%

[0037] Sodium oleoyl p-methoxyaniline sulfonate 0.8~2%

[0038] Carbon black 0.5~2%

[0039] Rubber powder 2~7%

[0040] Wood powder 1~5%

[0041] Sodium dodecylbenzenesulfonate 0.01~0.1%

[0042] Polypropylene fiber 1~3%

[0043] Water 1~10%,

[0044] Its preparation method is:

[0045] ①. Add butyl latex into the reaction kettle, add sodium salicylate and flattened O at a stirring rate of 2 to 3 rpm;

[0046] ②. Pour the compound antifreeze into the reaction kettle and stir for 25-35 minutes;

[0047] ③. Add carbon black, heat up to 45°C-55°C, and stir for 25-35 minutes;

[0048] ④. Add oleoyl p-methoxyaniline sodium sulfonate, h...

Abstract

The invention discloses a vehicle tyre self-complementing agent, which comprises the following parts: butyl latex, sodium salicylate, leveling O, composite freezing preventive, oleoyl p-methoxyl phenylamine thiophene sodium, carbon black, rubber flour, wood powder, sodium dodecylbenzene sulfonate, polypropylene fibre and water. The invention integrates cobra without leaking, which avoids tyre repair.

Description

technical field [0001] The invention relates to a chemical product, in particular to a vehicle tire self-healing agent, which can automatically repair the punctured hole after the tire is punctured by adding the self-healing agent into the tire. Background technique [0002] Since the British invented pneumatic tires, the human transportation industry has continued to develop, which brought convenience to human society, but also brought a series of troubles. When the vehicle is running on the ground, the tire is punctured due to encountering a hard object, causing air leakage and causing a lot of inconvenience to people. Therefore, once the tire is punctured while the vehicle is running, the puncture hole can be mended automatically, and the automatic tire sealant that ensures that the vehicle continues to travel safely emerges at the historic moment. However, due to various reasons, many products have defects of one kind or another. Some products precipitate and agglomerat...
