Abstract

The invention provides environment-friendly waterproof paint and a preparation method of the environment-friendly waterproof paint. The waterproof paint comprises the following ingredients: polymer emulsion, water, gamma-aminopropyl vinyl dimethoxy silicane, 2-ethoxyl-4-isothiazolin-3-ketone, a wetting agent, sorbitol, a thickening agent, hydroxypropyl carboxymethyl cellulose, an adhesive agent, a defoaming agent, a dispersant, an additive, a filling material and nano-powder. The paint takes a mixture of silicone acrylic emulsion and vinyl acetate-acrylic emulsion as a raw material and is endowed with higher elasticity; gamma-aminopropyl vinyl dimethoxy silicane serves as a waterproofing agent, so that the anti-seepage and waterproof performance of a paint layer is greatly improved; 2-ethoxyl-4-isothiazolin-3-ketone serves as a preservative of the paint, so that the corrosion resistance of the paint is further improved; and with the adoption of the hydroxypropyl carboxymethyl cellulose, the comprehensive performance of the paint is improved. Therefore, the prepared environment-friendly waterproof paint has the good waterproof performance, corrosion resistance and ageing resistance, and a low volatile organic compound content and meets environmental protection requirements.

Description

[0001] This application is a divisional application, the original patent number is: 201510686308.0, the application date is October 16, 2015, and the invention name is: an environmentally friendly waterproof coating and its preparation method. technical field [0002] The invention relates to the technical field of coatings, in particular to an environmentally friendly waterproof coating and a preparation method thereof. Background technique [0003] At present, decorative coatings for building walls can be divided into exterior wall coatings and interior wall coatings. Traditional coatings are commonly used, and most of the coatings are limited to the characteristics of high elasticity. Poor, low tensile strength, relatively low adhesion, so it is generally only used for interior decoration. [0004] With the improvement of people's requirements for the quality of living environment, more and more attention is paid to the decoration of building exterior walls. However, the...
