Abstract

The invention relates to a waterproof coating, in particular to a high molecular waterproof coating and a preparation method thereof. The high molecular waterproof coating is prepared from a powder material and a liquid material in the weight ratio of (1-5):1, wherein the powder material comprises the following components in parts by weight: 0.1-5 parts of reactive polysiloxane compound, 1-5 parts of polypropylene chopped fiber, 10-50 parts of quartz powder, 30-70 parts of calcium carbonate and 1-15 parts of bentonite; and the liquid material comprises the following components in parts by weight: 30-80 parts of polyvinyl acetate emulsion, 0.5-5 parts of thickening agent, 0.5-5 parts of sterilizing agent, 0.1-3 parts of organic silicon antifoaming agent and 10-40 parts of water. The high molecular waterproof coating has the advantages of no pollution to human bodies and the environment, readily-available raw materials, low cost, easiness for preparing, convenience for construction, safety, environment friendliness, excellent physical property, strong bonding force, high extensibility, prevention of water and rust and the like, and can be applied to waterproofness of indoor and outdoor buildings.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a polymer waterproof paint and a preparation method thereof. Background technique [0002] Seamless waterproofing is a worldwide problem in the construction industry. At present, the waterproof materials commonly used in the construction industry generally have problems such as high-temperature flow, low-temperature brittleness, low tensile strength, low elongation, and poor adhesion. When used on the exterior wall of a building, it is easy to cause aging, cracking, deformation, breaking, and delamination in a short period of time after being washed by rainwater and moisture, which not only affects the appearance, but also poses a great safety hazard; it is used in indoor buildings such as kitchens , bathrooms, etc., there are also problems such as difficult construction, frequent leakage, and inability to effectively protect the walls. No matter indoors or outdoors, if you want to keep it...
