Abstract

The invention relates to a single-component asphalt-based water-based non-cured rubber asphalt waterproof coating and a preparation method thereof. The coating is mainly prepared from the following components in parts by weight: 10-40 parts of asphalt, 10 to 40 parts of softening oil, 30-50 parts of water, 5-20 parts of anionic polymer latex, 1-3 parts of an anionic emulsifier, 1-3 parts of a nonionic emulsifier, 0.1-0.3 part of a stabilizer, 0.1-0.3 part of a defoaming agent, 0.1-0.3 part of a preservative, 0.1-0.3 part of a mildew preventive, 0.1-2.5 parts of a thickener and 5-15 parts of aninorganic filler. According to the invention, the waterproof coating overcomes the problems that existing oily non-cured rubber asphalt waterproof coatings contain harmful volatile substances and areharmful to human health and the problems that existing water-based non-cured rubber asphalt waterproof coatings have common performance or are double-component formulas and complex in construction process, and has the advantages of excellent bonding performance with waterproof coiled materials and various construction base layers (base surfaces) and favorable construction performance.

Description

technical field [0001] The invention relates to a one-component asphalt-based water-based non-curing rubber asphalt waterproof coating and a preparation method thereof, especially applied in the field of non-curing rubber asphalt waterproof coatings. Background technique [0002] The non-curing rubber asphalt waterproof coating can close the cracks and capillary pores of the construction base, and is suitable for complex construction work surfaces. The waterproof coating does not solidify for a long time after contacting with the air, and can always maintain a viscous colloidal state. It has strong self-healing ability, is sticky when touched, and is difficult to peel off. It still has good bonding performance at -20°C. However, traditional non-curing rubber asphalt waterproof coatings (generally oily non-curing rubber asphalt waterproof coatings) require special construction personnel to use special equipment for high-temperature spraying construction. The process is compli...
