Elastic waterproof polyurea coating as well as preparation method and application method thereof

Abstract

The invention belongs to the technical field of coating production and particularly relates to an elastic waterproof polyurea coating as well as a preparation method and application method thereof. The coating comprises a component A and a component B, wherein the component A comprises the main ingredients of aliphatic polyisocyanate trimer and an elastic isocyanate curing agent; the component B comprises the main ingredient of dimerization type asparaginic acid ester polyurea resin; the component A and the component B are packaged independently; a base coat layer is uniformly coated with the component A and the component B. The polyurea coating provided by the invention has the advantages as follows: the construction time of the polyurea coating is prolonged, the wettability is improved, and the performance of thick coating construction is provided, so that special polyurea coating equipment and special constructors are not required, the construction is facilitated, and the formed film has excellent elasticity. The polyurea coating can be dried after being coated for two hours, is high in curing speed, can be used outdoors, has excellent water resistance and chemical corrosion resistance of a swimming pool disinfectant, and can be soaked in water for a long time without cracking and leakage.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to an easy-to-construct elastic waterproof polyurea paint and a preparation method and application method thereof. Background technique [0002] With the rapid development of the national economy, people's living standards and consumption levels are getting higher and higher. As a kind of water theme park integrating leisure, entertainment, summer vacation and fitness, it has also emerged as the times require. Since the construction of Xianghong Ocean Park, the first water theme park in Asia, in the past two decades, especially in the past ten years, a large number of new water theme parks have been built in China. The water park is exposed to the outdoors. Except for a few months during the closing period, the water park is in an underwater or alternately wet and dry environment for a long time. The ground of the early water parks was not protected by painting, and it was...

Problems solved by technology

However, the existing polyurea coatings are mainly sprayed polyurea, which requires professional construction personnel and expensive professional equipment for construction, and the application period is extremely short, the curing speed is too fast, the adhesion is poor, and it is difficult to repair
