A kind of polymer modified asphalt composite waterproof material and preparation method thereof

Abstract

The invention belongs to the technical field of building waterproof materials, and particularly relates to a polymer modified asphalt composite waterproof material and a preparation method thereof. According to the technical scheme, the polymer modified asphalt composite waterproof material is prepared from a component A and a component B, and the component A comprises emulsified petroleum asphalt, neoprene latex, neoprene latex, an antifreezing agent, an antifoaming agent, a flexibilizer and industrial water. The component B comprises industrial alcohol, titanium dioxide, sodium carbonate, magnesium sulfate, sodium dodecyl benzene sulfonate, fatty alcohol polyethylene oxide ether succinic acid monoester sodium sulfonate and industrial water. After the component A and the component B are mixed, sprayed and cured, the polymer modified asphalt composite waterproof material is obtained. The component A and the component B both can be stored, transported and constructed at the temperature of -20 DEG C or above, forming is fast after the component A and the component B are mixed to be uniform, and the surface drying time is short. The formed composite waterproof material has excellent comprehensive performance, and does not crack in the environment at the temperature of -30 DEG C; due to the fact that titanium dioxide is added, the waterproof material has skin type breathability, and the bubbling phenomenon can be avoided in the forming and use processes.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and in particular relates to a polymer modified asphalt composite waterproof material and a preparation method thereof. Background technique [0002] Waterproof materials are a kind of widely used building materials and chemical products. At present, with the continuous expansion of my country's modernization construction projects, the requirements for waterproof materials and varieties are also increasing, and new waterproof materials are also emerging. At present, waterproof materials are mainly divided into two categories: solvent-based and water-based waterproof coatings. Since solvent-based waterproof materials generally contain organic solvents such as toluene, ketones, and aldehydes to pollute the environment and harm the health of construction workers, they are gradually eliminated. Water-based waterproof materials are the main development direction in recent years, ...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to solve the technical problems of the existing waterproof materials and their preparation methods, such as poor low temperature resistance of the emulsion before forming, long drying time for forming, easy damage to the base material and high cost, and provide a polymer modified asphalt composite The waterproof material and its preparation method, the two components of the waterproof material, A and B, can be stored, transported and constructed at a temperature of -20°C and above, and the two components of A and B are evenly mixed in a wide range of ratios and then sprayed When on the surface of the object to be sprayed, the polymer asphalt in component A will be rapidly precipitated and solidified by component B to form a waterproof film layer. The waterproof material has good weather resistance, adhesion, tensile strength, Elongation and waterproof, anti-seepage, moisture-proof, anti-corrosion and other characteristics overcome the shortcomings of the existing technology
