Abstract

The invention discloses a water-based liquid rubber waterproof paint, comprising a component A and a component B, wherein the component A comprises the following raw materials in parts by weight: 35-65 parts of emulsified asphalt, 5-40 parts of chloroprene rubber emulsion, 5-40 parts of styrene-butadiene latex, 0.1-10 parts of polyvinyl alcohol (PVA) stabilizer, 0.1-5 parts of anionic dispersant, 0.1-5 parts of defoamer and 0.1-10 parts of pH modifier; the component B comprises the following raw materials in parts by weight: 75-95 parts of water and 5-25 parts of soluble calcium salt and magnesium salt. The water-based liquid rubber waterproof paint belongs to a water-based dual-component waterproof paint, and the component A and the component B are sprayed and mixed by special spray equipment in use according to a certain ratio, so as to instantaneously solidify and form a film. The water-based liquid rubber waterproof paint can be sprayed on any substrate surface, and is especially good in surface adhesion on metal, concrete, plastic and the like.

Description

technical field [0001] The invention relates to the field of waterproof coatings, in particular to a water-based liquid rubber waterproof coating and a preparation method thereof. Background technique [0002] Spray rubber asphalt waterproof coating is called "Liquid Rubber" liquid rubber in foreign countries. It is a new type of non-polluting coating technology developed in foreign countries to meet the needs of construction and environmental protection after the low (no) pollution coating technology such as polyurea in the past 10 years. Solvent, pollution-free green products. This type of product and related technology has been researched and developed in Canada since 1999, and was officially introduced to the market in 2003. The product has excellent waterproof and anti-corrosion properties. This process is a rapid-response spraying system. The raw material system does not contain solvents, the curing speed is fast, and the process is simple. It can conveniently spray a...
