Abstract

The invention discloses a liquid rubber spray coating. The liquid rubber spray coating comprises a component A and a component B; the component A is an anionic liquid rubber asphalt emulsion; the component B is a coagulant solution; in the component A, according to the mass percentage, the weight solid content of the liquid rubber asphalt emulsion is 50-75%, wherein 1-35% of a rubber emulsion, 10-50% of an asphalt emulsion, 0.01-2% of an anionic dispersant, 0.01-2% of an anionic surfactant, 0.1-10% of fatty alcohol polyoxyethylene ether, 0.1-10% of OEP-70, 0.1-10% of AEP, 0-3% of carbon black,0-3% of a fine powder and 0.5-3% of a magnetic solid powder are contained; a proper amount of the magnetic solid powder is added in the component A, when the coating is sprayed on an iron pipeline surface, the addition of the magnetic powder makes a spray-coating layer and an iron base layer combined more firm.

Description

technical field [0001] The invention belongs to the technical field of rubber coating, in particular to a liquid rubber spray coating. Background technique [0002] Coatings with multiple anti-corrosion functions, waterproof functions, protective functions, thermal insulation functions, sound absorption and noise reduction functions, and flame-retardant functions are very much needed materials for engineering construction in the construction industry. Especially in the protective construction of underground, road bridge, and tunnel engineering, it is necessary to coat the tunnel face with a layer of waterproof protective layer as soon as possible after excavation, and it is hoped that it will be cured soon. [0003] The anti-corrosion layer in the prior art has great limitations and can only be used indoors and on non-exposed roofs. It is easily damaged, smelly, not environmentally friendly, and difficult to control the thickness; it is not easy to make thicker, which affect...
