Abstract

The invention discloses a monocomponent tire explosion-proof liquid and a preparation method thereof, which comprises the following raw materials by weight: 41-63 parts of aqueous polyurethane, 18.2-29 parts of polyether 220, 6-9.5 parts of toluene diisocyanate, 10-15.5 parts of plasticizer, 1-3.4 parts of pH stabilizing agent, 0.5-1 part of dispersant, 0.5-1 part of coalescing agent and 0.1-0.3 parts of antifoaming agent. The monocomponent tire explosion-proof liquid can be used for coating on the inner surface of the tire to form polymeric membrane, so that effects of explosion resistance, prick resistance, leakage resistance, noise reduction life prolongation, energy saving, oil saving and dynamic balance can be reached, machinery is not required while operation is carried out, operation can be completed through manual operation, the raw material price is low, preparation is simple, science and technology content is high, profit margin is large, and market advantage is obvious.

Description

technical field [0001] The invention relates to the field of tires, in particular to a single-component tire explosion-proof fluid and a preparation method thereof. Background technique [0002] In today's life, more and more families use cars as a necessary means of transportation for going out, and tires are an indispensable part of the car. The commonly used tires are tubeless tires. If you accidentally encounter pinning or Trachoma causes the tire to leak air or even blow out, and the tire is basically scrapped. The main component of tire repair materials in the past is glue, which has the disadvantages of low strength, easy repeated damage, and incomplete repair. Contents of the invention [0003] In order to prevent tires from leaking or even blowing out, the invention provides a single-component tire explosion-proof liquid and its preparation method. The single-component tire explosion-proof liquid can be applied to the inner wall of the tire to form a layer of pol...
