Problems solved by technology

Some tire sealants use various natural fibers or asbestos fibers and chemicals. These fibers will gradually agglomerate in the tire, lose the effect of tire sealant, wear the inner wall of the tire, and make the vehicle vibrate when driving

Embodiment

[0010] Embodiment: A proper amount of tire sealant is injected into the tire through the air valve, and then the tire is fully inflated. When the vehicle is running, due to the action of centrifugal force, the supplementary fluid forms a protective film inside the tire, and the rest of the fluid is dispersed in the tire. in motion. When the tire is punctured by nails or other sharp and hard substances, the air that is released violently will bring the mixture into the hole, and the hole will be filled instantly and firmly. If it is found that the tire has been pierced with nails or other foreign objects, it should be removed, and the vehicle should be driven or the tire should be rotated, and the hole will be repaired immediately. Although it is mainly designed for prevention, it can also be used to repair tires that have been punctured by sharp objects. As long as the hole is less than 6mm, it can be filled. The method is to inject an appropriate amount of sealant fluid int...

Abstract

The invention discloses a novel automatic inflation tire repair liquid belonging to a high molecular chemical material. The tire repair liquid comprises the following components in parts by weight: 48.0g to 54.30g of ethylene glycol, 2.5g to 4.0g of nitrile butadiene rubber powder and particles, 1.25g to 1.70g of polyamide fiber, 0.5g to 1.5g of bentonite gel, 0.60g to 0.70g of carboxymethyl cellulose, 0.20g to 0.30g of sodium nitrite, 0.20g to 0.30g of borax, 0.15g to 0.20g of dimethyl silicone oil and 37g to 46.6g of water, wherein the sum of weights of all the components is 100; the viscosity of the entire mixed liquid is between 50.000CPS and 60.000CPS; and the pH value of a product is neutral and is preferably adjusted by using disodium phosphate or sodium phosphate. The tire repair liquid has the advantages of high tire repair speed, high tire repair capacity, capability of filling fine holes and holes with diameter of 6mm, long duration and great market potential, is suitable for various tires, is kept in a liquid state for a long time after being injected into a tire, does not freeze at the temperature of -40 DEG C and is not decomposed at the temperature of 100 DEG C.

Description

technical field [0001] The invention belongs to macromolecular chemical materials, and is a novel self-inflating tire repair fluid composed of various macromolecular chemical materials. Background technique [0002] Traditional tire repair: the vehicle should be stationary, the wheels should be removed, and the inner tubes should be pulled out if there are inner tubes. Repairing with inner tubes generally adopts cold patching or fire patching. The method is generally to use a file to coat the inner tubes, that is, the tread must be very clean, and the tires are completely repaired by the adhesive force of the glue. Such patched tires are very easy to be glued when the vehicle is running at high speed, especially in hot summer. One method of repairing tubeless tires is fire repair from the inside, which is very troublesome. The other method is to apply rubber strips. After the rubber strips are applied, after a period of time, the rubber strips age and slowly deflate, and so...
