Abstract

The invention relates to the technical field of building waterproofing materials, and concretely relates to a liquid coiled material waterproofing coating and a preparation method thereof. The liquidcoiled material waterproofing coating least comprises 25-35 wt% of an acrylic emulsion, 25-35 wt% of a powder, 25-35 wt% of asphalt, 0-10 wt% of water and 1-6 wt% of an auxiliary agent. A coating layer formed by the liquid coiled material waterproofing coating has the advantages of high elasticity, high extensibility, high density and high elongation, so the coating layer has very good adaptability to deformation, cracking and the like of a base layer, and has obvious superiority in construction of complex parts. Additionally, the waterproofing coating has the advantages of environmental friendliness, waterborne property, odorlessness, and convenience in construction. A seamless and complete elastic waterproof layer is formed after the waterproofing coating layer is cured, so the waterproof and anti-seepage capacity of constructional engineering is improved; and the maintenance is convenient, and the original waterproof effect can still be achieved only by locally maintaining the damaged part.

Description

technical field [0001] The invention relates to the technical field of building waterproof materials, in particular to a liquid coil waterproof coating and a preparation method thereof. Background technique [0002] Liquid coil waterproof coating is a one-component pure water-based environmental protection product. The product contains high molecular polymer and high-quality emulsified asphalt. The high polymer and asphalt are completely integrated through a special modification process. The solid content is high and the drying speed is fast. Fast, with strong adhesion to the concrete base. After curing, it forms a highly elastic, black and bright waterproof coating film. The waterproof coating film has the effect similar to rubber coils, and has excellent low-temperature flexibility and high-temperature sag resistance. As the non-leakage connection between the engineering foundation and the building, it is the first barrier for the waterproofing of the entire project and pl...
