A single-component waterproof coating film for pasting ceramic tiles and its preparation method

Abstract

The invention discloses a one-component waterproof coating film for pasting ceramic tiles, which comprises the following components calculated in parts by weight: 45-60 parts of styrene-butadiene emulsion; 0.3-0.6 parts of dispersant; 0.1-0.3 parts of blue paste 3-4 parts of titanium dioxide slurry; 0.1-0.2 parts of pH regulator; 0.4-0.6 parts of alkali swelling thickener; 0.5-1 part of antifreeze; 0.5-1 part of film-forming aid; ‑0.2 part; 0.3‑0.5 part of bactericidal preservative; 1.6‑4.6 part of water; 10‑15 part of barium sulfate; 12‑38.2 part of heavy calcium powder. The one-component waterproof coating film used for pasting ceramic tiles of the present invention has good two-way affinity with the base layer and the ceramic tile bonding layer, can effectively resist waterproof damage caused by cracking of the base layer, and can also pass the EN14891:2013 test Test method for bridging cracks in coating films.

Description

Technical field [0001] The present invention relates to the field of waterproof coating, in particular, the present invention relates to one-component waterproof coating and a method for preparing a ceramic tile paste [0002] technical background [0003] Currently home decoration, kitchen, bathroom waterproofing is essential for a process, not as waterproof, leak renovate the house in the event not only brings economic losses, will result in a greater impact on life. The market is generally used polymer cement waterproof material waterproof treatment, in order to avoid the tiles pasted late fall, generally only use some low elastic or rigid waterproofing slurry for waterproofing, and waterproofing products such easily damaged by cement sand grassroots cause slight cracking water damage, resulting in leakage. Waterproof slurry while the polymer cement is liquid and powders of two components, mixing the construction site and then stir the construction, the construction of the base...

AI Technical Summary

Problems solved by technology

[0003] At present, in home decoration, the waterproof treatment of kitchen and bathroom is an indispensable process. If waterproofing is not done, once the renovated house leaks, it will not only bring economic losses, but also have a greater impact on life.

In the market, polymer cement waterproof materials are generally used for waterproof treatment. In order to avoid the tiles pasted in the later stage from falling off, generally only some low-elastic or rigid waterproof slurry can be used for waterproof treatment, and such waterproof products are easily damaged by cement sand. Minor cracks in the base layer lead to waterproofing failures, which eventually lead to leaks

At the same time, the polymer cement waterproof slurry is composed of two components: liquid agent and powder agent. During construction, it is mixed fully and evenly on site before construction. During construction, it is necessary to clean the base, wet the base, maintain for 48-72 hours or more, and test the water. After passing the acceptance, proceed to the next process, the process is relatively complicated
