Rubberized asphalt non-cured water-proof coating and preparation process thereof

Abstract

The invention discloses a rubberized asphalt non-cured water-proof coating and a preparation process thereof. The coating consists of the following components in percentage by weight: 20-25 percent of rubber, 15-20 percent of carbon black, 1-2 percent of zinc oxide, 30-50 percent of asphalt, 1-2 percent of accelerator and 5-8 percent of adhesive. The water-proof coating not only improves the waterproofness and the weathering resistance of a building, but also further improves acid resistance, has the characteristic of alkali resistance. The problems of waterproofing work such as thermal expansion and contraction, building slit displacement, corrosion resistance, fatigue resistance and the like are solved, the solid content is up to over 95 percent, and the coating is free from volatile matters, has permanent curing resistance, makes the knife edge of a knife inserted into the coating and pulled out recover quickly without draining any water, has high self-healing, corrosion resistance, fatigue resistance and high bonding power with a plurality of heterogeneous materials, can be applied to thermal spraying construction, knife-coat construction and grouting leakage preventing construction, and can be widely applied to waterproofing of subways, bridges, houses, water pools and the like.

Description

technical field [0001] The invention belongs to the technical field of waterproof paint and its preparation process, and in particular relates to a rubberized asphalt non-curing waterproof paint capable of forming a waterproof layer and its preparation process. Background technique [0002] Waterproof coatings are commonly used building waterproof construction materials, but leakage defects are common in cement concrete buildings, especially thermal expansion and contraction, displacement of building joints, corrosion resistance, and fatigue resistance have always been difficulties in waterproofing projects. In order to solve these problems, although there are many kinds of waterproof coatings in the market at present, although they have advantages such as low price, their anti-leakage ability is relatively poor, the construction is complicated, and the environment is polluted very much, so it is difficult to widely promote and use them.

Problems solved by technology

[0004] The purpose of the present invention is to provide a waterproof coating with rubberized asphalt as the main waterproof component, which can be used for scraping, spraying and grouting plugging construction, and has obvious high impermeability, which solves the problem that waterproof coatings on the market cannot cope with. Defects of building deformation joints, displacement joints, thermal expansion and contraction joints, and the coating will never cure
