Waterproof coating for toilets as well as preparation method and application of waterproof coating

Abstract

The invention discloses a waterproof coating for toilets as well as a preparation method and application of the waterproof coating. The waterproof coating comprises a component A and a component B, wherein the component A is a calcium solution with a mass fraction of 30-50%; and the component B comprises the following components in parts by weight: 50 to 70 parts of a silicate solution, 0.5 to 1 part of a surfactant, 1 to 1.5 parts of a complexing agent, 0.1 to 1.5 parts of sodium polyacrylate and 25 to 50 parts of deionized water. The waterproof coating disclosed by the invention has a very good waterproof effect, can compact concrete and mortar and improve the impermeability of the concrete and the mortar, is a capillary crystalline material, can be integrated with a structure after being used, is resistant to water soaking and corrosion, has the same service life as the concrete structure, is good in durability, can be self-healed and realizes waterproof action for a long time. The waterproof coating disclosed by the invention is simple and convenient to prepare, convenient to construct, free of harmful cancerogenic substances such as benzene, friendly to environment, low in cost and short in construction period, and a closed water test can be performed in 24 hours.

Description

technical field [0001] The invention relates to indoor architectural coatings, in particular to a toilet waterproof coating and its preparation method and application. Background technique [0002] Bathroom waterproofing is divided into floor waterproofing and wall waterproofing. The purpose of floor waterproofing is to prevent bath water or laundry water accumulated on the ground from penetrating downstairs. It is an application scenario where water accumulates all year round, so the waterproof material used The water resistance is better, and it can withstand a certain amount of weak acid and alkali; after the wall is waterproofed, tiles are required, so the waterproof material is usually rigid to prevent bricks from falling off in the later stage. [0003] At present, the commonly used materials for bathroom floor waterproofing on the market include polymer cement waterproof coating (referred to as JS waterproof coating), emulsified asphalt waterproof coating or polyureth...

AI Technical Summary

Problems solved by technology

However, the surface of film-forming coatings is relatively smooth, and it is often necessary to roughen the surface before tiling, and in order to ensure that it does not turn around in the later stage, special adhesives such as tile adhesives are often required when tiling, which increases the process and cost.

[0004] To sum up, the current pain point of bathroom waterproofing is: for the waterproof coatings commonly used on toilet floors, the common problem is that oil-based coatings are not environmentally friendly and expensive, and water-based coatings are not resistant to blisters, especially weakly corrosive water.

For the waterproof coatings commonly used on bathroom walls, the common problem is that there is a risk of bricks falling off, and the process is complicated, especially in winter when the temperature is low, and most water-based coatings cure slowly, which affects the construction period
