Problems solved by technology

The invention uses styrene-butadiene emulsion, which has poor UV resistance and is not suitable for exposure; the weight ratio of liquid material and powder material is liquid material: powder material = 1:2.77~1:3.33, and the invention is a mortar product with a high liquid-to-powder ratio. Its product has extremely low elongation, no elasticity, and extremely poor crack resistance against the base layer, so it is not suitable for direct exposure as a waterproof material; this material is non-exposed, does not have coloring, and has no decorative function
This invention is a mortar with a high liquid-to-powder ratio. It needs to have a sufficient thickness (2-4mm) during construction to have a certain waterproof performance, and it is not suitable for direct construction on the existing finish layer (tile surface, latex paint surface)

Abstract

The invention relates to waterproof mortar for exterior wall decoration and a preparation process thereof. The waterproof mortar is prepared by mixing a liquid material and a powder material according to a weight ratio of 1: (1-1.5), wherein the liquid material is composed of the following components in parts by weight: 20 to 40 parts of a pure acrylic emulsion, 30 to 50 parts of an elastic waterproof emulsion, 0.3 to 0.5 part of an antifoaming agent, 0.5 to 1.0 part of a dispersant, 5 to 10 parts of a film-forming auxiliary agent, 0.05 to 0.1 part of a thickening agent, 0.10 to 0.15 part of a wetting agent, 2 to 5 parts of a pigment and 3 to 5 parts of water; and the powder material is composed of the following components in parts by weight: 30 to 50 parts of high-alumina cement, 30 to 40 parts of quartz sand, 10 to 20 parts of calcium carbonate and 5 to 10 parts of kaolin. Compared with the prior art, the waterproof mortar provided by the invention solves the technical problems of complicated construction process, complicated process, high cost, poor waterproof performance, etc. The waterproof mortar provided by the invention is especially applicable to application in exterior wall maintenance, can be directly constructed on an original external layer without the need of removing the original external layer, and realizes one-step formation of water prevention and decoration.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a waterproof mortar for exterior wall decoration and a preparation process thereof. Background technique [0002] Waterproof mortar for exterior wall decoration is a two-component water-based waterproof coating composed of liquid material and powder material, which has broad application prospects in exterior wall decoration. At present, most of the external wall finishes used in the market are latex paint, real stone paint, marble, ceramic tile, etc. The construction is complicated, the process is complicated, the application cost is high, the waterproof performance is poor, the material consumption per square meter is high, and it is easy to peel. Shedding and cracking greatly affect its use. Waterproof mortar for exterior wall decoration does not need to be used as a primer, top coat, or putty layer like latex paint. risk of shedding. This product can be directly sprayed ...
