Self-repairing macromolecule nanometer tyre cement and preparation method thereof

Abstract

The invention discloses self-repairing macromolecule nanometer tyre cement, which is prepared from the following raw materials in parts by weight: 15-22 parts of crylic acid, 8-10 parts of quartz powder, 13-18 parts of nonyl phenol, 9-15 parts of ammonium hydroxide, 4-8 parts of nano-zinc oxide, 13-16 parts of nano-silicon sol, 20-24 parts of isocyanate, 3-7 parts of trichlorofluoromethane, 5-15 parts of water glass, 22-24 parts of amino resin, 6-10 parts of sorbitan monooleate, 12-15 parts of ammonium polyphosphate, 5-8 parts of zinc borate, 7-11 parts of methyl anyl alcohol, 13-18 parts of active carbon nanoparticles, 16-20 parts of vinyl acetate, 22-24 parts of cobalt soap, 12-16 parts of isononanoic acid, 18-22 parts of polyurethane, 6-10 parts of titanium dioxide, 13-18 parts of trichloro ethylene and 24-28 parts of dibasic ester. The macromolecule nanometer tyre cement is high in bonding strength, good in anti-ageing effect and small in shrinkage rate, and can be bonded and molded at a room temperature, and the automatic repairing effect is achieved.

Description

technical field [0001] The invention relates to a self-repairable polymer nano tire sealant and a preparation method thereof. Background technique [0002] The existing tire repairing agent is a non-toxic, tasteless, non-flammable and non-sticky liquid, which can not only repair the tire but also inflate it. The main components of puncture sealant are generally rubber and inflating agent, and the pH value is neutral. When the tire is punctured and leaks air, just connect the puncture sealant to the tire, press the valve of the puncture sealant, and compressed air will be automatically added to the tire, and white tire sealant like hair gel will also be injected. After the tire pressure is normal, the car can be driven on the road again. Generally speaking, after adding puncture 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 repair the tire. The sealant in the tire will...

AI Technical Summary

Problems solved by technology

For example, if a leak-repairing tire has already leaked out, it will be difficult to work.

The biggest defect of this kind of puncture sealant is that it is very corrosive. Whether it is a steel rim or an alloy rim, it will be damaged for a long time, and the direct result of this damage is that the steel rim and the tire are not sealed properly. Strictly cause air leakage

[0007] The existing tire sealant has low bonding strength, poor anti-aging effect, large shrinkage rate, cannot be bonded and formed at room temperature, and cannot achieve the effect of automatic repair
