Abstract

The invention discloses a polymer cement-based waterproof coating with a photocatalytic function. The polymer cement-based waterproof coating consists of an inner layer coating and an outer layer coating. The invention also discloses a preparation method of the polymer cement-based waterproof coating. By adopting the polymer cement-based waterproof coating, the construction period can be greatly shortened, the surface drying time is finally reduced by 1 to 3 h, and the actual drying time is reduced by 2 to 4 h. Nano TiO2 is used as an ultraviolet shielding agent, a double-layer material is formed by utilizing the different particle size and crystal forms, the inner layer large-particle-size rutile-type nano TiO2 reflects the ultraviolet rays, and the outer layer small-particle-size anatase-type nano TiO2 absorbs the ultraviolet rays, so that the anti-aging performance of the coating is significantly improved.

Description

technical field

[0001] The invention relates to the field of waterproof materials, in particular to a polymer cement-based waterproof coating with photocatalytic function and its application. Background technique

[0002] In recent years, water leakage incidents have occurred frequently due to poor waterproofing of underground structures and buildings. Leakage in buildings not only adversely affects the living environment of residents, but also corrodes the steel bars in the concrete, thereby destroying the integrity of the concrete structure, thereby affecting the stability and service life of the main structure. Therefore, doing a good job of waterproofing the building will not only bring a comfortable living environment to the residents, but also be particularly important to the service life of the main structure.

[0003] Polymer cement-based waterproof coatings in waterproof coatings are composed of emulsions synthesized by various water-based polymers and high-quality...
