Problems solved by technology

[0003] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the exterior decoration of buildings is getting more an

Abstract

The invention belongs to the field of coating preparation, and particularly relates to a waterproof coating and a production method thereof.The waterproof coating is prepared from 40-60 parts of epoxy modified polyether polyol, 20-30 parts of polyisocyanate monomers, 20-30 parts of plasticizer, 1-5 parts of latent curing agent, 0.3-3 parts of catalyst, 0.1-2 parts of defoaming agent, 1-5 parts of anti-sagging agent, 10-20 parts of graphene oxide and 5-10 parts of silane coupling agent. According to the scheme, the graphene oxide is added, and the graphene oxide is tiled in a coating film to form a multi-layer compact structure, so that the waterproof performance of the coating is improved, and meanwhile, the extensibility of a waterproof film formed by the coating is improved; hydroxyl groups on the surface of the graphene oxide respectively react with the silane coupling agent, so that the extensibility of a waterproof film formed by the coating is improved.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to a waterproof paint and a production method thereof. Background technique [0002] Waterproof coating refers to a kind of coating that the coating film formed by coating can prevent rainwater or groundwater from seeping. According to the coating state and form, waterproof coatings can be divided into: emulsion type, solvent type, reactive type and modified asphalt. The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. [0003] At present, traditional coatings are generally used for the decoration of building walls. Most of the coatings are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for int...
