Abstract
The invention especially relates to a preparation method and construction process for an elastic waterproof roof paint, belonging to the technical field of waterproof materials. The preparation methodis composed of a preparation method for a priming paint and a preparation method for a finishing paint. The priming paint comprises a component A and a component B. A preparation method for the component A of the priming paint comprises the following steps: stirring 15 to 25 parts of deionized water and 0.1 to 0.3 part of cellulose for 5 to 10 min until the cellulose is completely dissolved; adding 20 to 35 parts of a curing agent, 0.5 to 1.5 parts of propylene glycol, 0.1 to 0.5 part of a wetting agent, 1 to 4 parts of a dispersant and 30 to 50 parts of a pigment and filler and carrying outdispersion under stirring for 0.5 to 1 h; then adding 0.2 to 0.5 part of an antifoaming agent and 2 to 5 parts of a flash-rust inhibitor and carrying out stirring for 20 to 30 min; and adding 0.1 to 0.3 part of a thickening agent, 0.2 to 0.5 part of a leveling agent and 0.1 to 0.2 part of a bactericide and carrying out stirring for 20 to 30 min. The elastic waterproof roof paint provided by the invention has the beneficial effects of excellent elastic properties, an anti-rust function and good waterproof performance.
Description
technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a preparation method and construction process of an elastic roof waterproof coating. Background technique [0002] Coatings are materials that can be applied to the surface of an object to be coated and form a firmly adherent continuous film. This material can be coated on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. It belongs to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. A general term for a class of liquid or solid materials that can form a solid coating film with protective, decorative or special properties (such as insulation, anti-corrosion, waterproof, signs, etc.) when applied to the surface of an object. [0003] Elastic roof waterproof coating is an elastic and seamless coating system for the roof, which ...
