Problems solved by technology

However, when natural rubber is used, it needs to be soaked in toluene to make it expand and soften. After absorbing the toluene released by the rubber particles, the tire will become brittle and easy to crack. Moreover, toluene is a dangerous product and is easy to explode.

[0032] The preparation method of above-mentioned automatic tire sealant liquid, comprises the following steps:

[0033] Step 1: Pour the natural rubber emulsion into the mixer, and stir for 10-20min at a stirring speed of 100-300rpm;

[0034] Step 2: Add surfactant and continue stirring for 10-20min;

[0035] Step 3: Add dispersant, silicone oil, and antifreeze and continue stirring for 10-30 minutes, then seal and fill.

preparation Embodiment 1

[0037] According to weight percentage, take 42% of natural rubber latex, 18% of ammonia water, 5% of sodium lauryl sulfate, 6% of silicone oil, and 29% of glycerol.

[0038] Pour the natural rubber emulsion into the mixer, and stir for 10 minutes at a stirring speed of 100 rpm; add sodium lauryl sulfate, and continue stirring for 10 minutes; add ammonia, silicone oil, and glycerin, continue stirring for 10 minutes, and seal the filling. .

preparation Embodiment 2

[0040] According to weight percentage, take 62% of natural rubber latex, 15% of ammonia water, 4% of sodium lauryl sulfate, 5% of silicone oil, and 14% of glycerol.

Abstract

An automatic tire repairing agent is prepared from, by weight percent, 42-62% of natural rubber latex, 15-20% of dispersant, 4-6% of surfactant, 4-6% of silicone oil and 14-29% of antifreezing agent.The solid content of natural rubber latex ranges from 30% to 60%; the dispersant refers to one or a mixture of multiple of sodium methylene bis-naphthalene sulfonate and ammonium hydroxide; the surfactant refers to one or a mixture of multiple of sodium dodecyl benzene sulfonate, lauryl sodium sulfate, fatty alcohol-polyoxyethylene ether and fatty alcohol; the antifreezing agent refers to one or amixture of multiple of ethylene glycol, propylene glycol, glycerol and ethylene glycol monobutyl ether. The automatic tire repairing agent is applicable to repairing of leaky vacuum tires, and is easy, safe, sanitary and rapid to use, capable of meeting work requirements with the temperature of 40 DEG C below zero, and is free of harmful substance such as phosphorus and halogen.

Description

technical field [0001] The invention relates to a chemical adhesive, in particular to a tire sealant. Background technique [0002] Traditional tire repair requires the vehicle to be stationary, the wheels to be removed, and the inner tube to be removed if there is one. It is very troublesome, a lot of time wasted, and the work efficiency is low. Therefore, since the tire sealant, when the tire is punctured and air leaked, just connect the tire sealant to the tire, press the valve of the sealant, and the compressed air will be automatically added to the tire, and the tire sealant will also be injected at the same time. liquid. After the tire pressure is normal, the car can be driven on the road again. Generally speaking, after adding tire sealant to the tire once, as long as the liquid in the tire does not evaporate and leak, even if the tire is punctured again later, there is no need to seal the tire. The sealant in the tire will fill the hole on the tire by itself under...
