Problems solved by technology

[0003] However, high solid content no-bake rubber asphalt products are very strict in the selection of components. If the components, especially the emulsifier, are not properly selected, problems such as low cloud point or coarse asphalt particles may easily occur
These problems make the self-hardening rubber asphalt coating unable to meet the construction technology requirements, which greatly limits its development.

Abstract

The invention provides self-hardening rubber asphalt paint which comprises the following components by weight percent: 50%-65% of asphalt, 3%-6% of cationic emulsifier, 3%-6% of nonionic emulsifier, 25%-35% of modified latex, 1%-3% of stabilizer and 5%-10% of filler. The invention further provides a preparation method of the self-hardening rubber asphalt paint, the rubber asphalt paint is modified through normal-temperature self-crosslinking emulsion, has the prominent characteristics of normal temperature spray coating, manual scrape-coating, instant shaping, perfect joint, high elastic force, zero joints and the like, and can fundamentally solve the technical difficulty of leakages at side angles, gaps and junction of irregular structures and the like, thereby thoroughly updating the traditional construction process and the method of waterproof material.

Description

Technical field [0001] The invention relates to a coating, especially a self-hardening rubber asphalt coating used in the field of waterproof and anticorrosion. Background technique [0002] In recent years, the country has strengthened investment in infrastructure and has been emphasizing environmental protection, energy saving and emission reduction. The high solid content self-hardening rubber asphalt coating is a world-class multi-purpose environmentally friendly waterproof product with room temperature spraying, instant performance, and perfect adhesion. The outstanding characteristics of joint, high elasticity, and no joints fundamentally solve the technical problems such as the leakage of corners, gaps, and irregular structure joints, and completely update the construction technology and methods of traditional waterproof materials. Hard rubber asphalt coatings will surely lead the new trend of technology upgrading in the field of waterproofing. [0003] However, high solid ...
