AI Technical Summary

Problems solved by technology

However, the non-curing waterproof coatings on the market are viscous and gelatinous, with extremely strong cohesive force. It is very difficult to directly scrape and apply them. They often need to be heated and melted. High-temperature heating will not only easily cause excessive aging of asphalt, but also cause cancer. A large amount of volatilization of benzopyridine; in addition, the non-curing waterproof coatings currently on the market are generally not suitable for direct use on wet base surfaces, and often need to be coated after the base surface is dry, and the abrasion resistance is poor. Therefore, There is an urgent need for a waterproof coating that is heat-free, has good abrasion resistance and is suitable for wet base surfaces

Abstract

The invention provides a wear-resistant asphalt-based waterproof coating, which is prepared from the following raw materials in parts by weight: 30 to 50 parts of emulsified asphalt, 10 to 20 parts of styrene-acrylic emulsion, 20 to 30 parts of auxiliaries, 0.2 to 0.4 part of dispersing agents, 0.1 to 0.3 part of defoaming agents and 0.1 to 0.3 part of sterilizing agents. In addition, the invention also provides a method for preparing the waterproof coating, which comprises the following steps: S1, adding the emulsified asphalt and the styrene-acrylic emulsion into a reaction kettle, and uniformly stirring to obtain a mixed emulsion; s2, adding an auxiliary agent into the mixed emulsion, and uniformly stirring; and S3, adding the rest components into the product obtained in the step S2, and uniformly stirring to obtain the waterproof coating. The wear-resistant asphalt-based waterproof coating provided by the invention is a non-cured pasty waterproof coating, can be directly used at normal temperature, is suitable for a wet base surface, and has relatively good water resistance, weather resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to a wear-resistant asphalt-based waterproof coating and a preparation method thereof. Background technique [0002] At present, my country's waterproof coatings are still mainly based on asphalt-based waterproof coatings, especially the research and application of modified asphalt waterproof materials are developing rapidly. Non-curing rubber asphalt waterproof coating (abbreviated as non-curing waterproof coating) is a kind of waterproof material with creep property, which is mainly made of rubber, asphalt and special additives, and maintains a viscous paste for a long time in the application state. Because it is solvent-free and never cured, it is widely used in roofing, basement, side wall waterproofing of civil buildings, as well as sidewall and roof waterproofing of subways, stations and tunnels because of its strong adaptability to the base layer, outstanding cree...
