Embodiment 1

[0037] The invention discloses a waterproof coating for toilets, which comprises components A and B, and component A is calcium nitrite solution with a mass fraction of 30%.

[0038] Component B includes 56 parts of silicate solution, 0.5 parts of sodium dodecylbenzenesulfonate, 1.5 parts of EDTA-2Na, 1 part of sodium polyacrylate and 41 parts of deionized water in parts by mass, wherein the silicate solution is A mixture of sodium silicate solution and lithium silicate solution, the mass ratio of the two is 1:1;

[0039] The preparation method is as follows: turn on the mixer, add calcium nitrite and water to the mixer according to the proportion, stir evenly, and let it stand for 20-30 minutes to obtain component A; add deionized water and polyacrylic acid to another mixer according to the proportion Stir with sodium for 30 minutes to obtain a uniform solution, then add sodium dodecylbenzenesulfonate and stir for 15 minutes, then add EDTA-2Na and silicate solution, and stir ...

Embodiment 2

[0041] The preparation method of embodiment 2 is the same as that of embodiment 1, the difference is that the ratio of component B by mass fraction is: 60 parts of silicate solution, 1.0 parts of sodium dodecylbenzenesulfonate, 1.5 parts of EDTA-2Na , 1 part of sodium polyacrylate and 36.5 parts of deionized water.

Embodiment 3

[0043] The preparation method of Example 3 is the same as that of Example 1, except that the ratio of component B by mass fraction is: 65 parts of silicate solution, 1.0 parts of sodium dodecylbenzenesulfonate, and 1.5 parts of EDTA-2Na , 1 part of sodium polyacrylate and 31.5 parts of deionized water.

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...
