Abstract

The invention discloses environment-friendly strengthened flexible waterproof paint and a preparation method thereof, belonging to the technical field of paint applications. The environment-friendly strengthened flexible waterproof paint is used for solving the problems in the prior art that waterproof paint is low in strength and cannot cover fine cracks. The environment-friendly strengthened flexible waterproof paint is characterized by being prepared from an ingredient A and an ingredient B, wherein the ingredient A is prepared from pure acrylic acid emulsion, a defoaming agent, environment-friendly bactericide and water, the ingredient B is prepared from silicate cement 42.5, quartz sand 70-140, quartz sand 200 and a water reducing agent, and the weight ratio of the ingredient A to the ingredient B is 1: (1.5-2.0). The invention further provides the preparation method of the waterproof paint. The waterproof paint disclosed by the invention is not only high in strength, but also can cover the fine cracks, so that the phenomenon of water leakage during construction caused due to the fact that the strength is not enough and the fine cracks cannot be covered is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of paint application, and in particular relates to an environment-friendly reinforced flexible waterproof paint and a preparation method thereof. Background technique [0002] With people's requirements for environmental protection, the application of environmentally friendly waterproof coatings is becoming more and more extensive. According to the national standard classification in the market, it can be roughly divided into three categories. Each type of waterproof coating has different emphases, and the indicators such as elongation at break, bond strength, and tensile strength vary greatly. Existing waterproof coatings will have a good waterproof effect under the condition of low strength requirements and no cracking, but in actual engineering applications, they are often not carried out under such ideal conditions. In addition, although some types of waterproof coatings have high strength, they do not ...
