Abstract

The invention relates to the technical field of paints, and discloses an environmentally-friendly waterborne multicolor paint, a preparation method and an application method of the paint. The environmentally-friendly waterborne multicolor paint is prepared by using the following preparation method comprising: a first step of preparing a base paint: weighing 0.6-1 parts of hydroxyethyl cellulose, 0.1-0.2 parts of pH (Potential of Hydrogen) regulator for the base paint, 0.3-0.5 parts of amine salt dispersant, 0.2-0.5 parts of defoaming agent for the base paint, 0.15-0.3 parts of preservative for the base paint, 1-4 parts of titanium dioxide and 8-15 parts of filling agent in parts by weight. The environmentally-friendly waterborne multicolor paint disclosed by the invention is good in storage stability; a colored particle is more lasting in stability; the constructed paint surface is good in water resistance, alkali resistance and washing resistance, strong in crack covering capacity, and good in artificial weathering aging effect; the content of a volatile organic compound in the environmentally-friendly waterborne multicolor paint disclosed by the invention is low, so that the paint is safer and more environmentally-friendly after application and construction.

Description

technical field [0001] The invention relates to the technical field of coatings, and relates to an environment-friendly water-based colorful coating and a preparation method and application method thereof. Background technique [0002] The traditional water-based exterior wall latex paint no longer meets people's needs due to its monotonous color and poor crack resistance; and the new type of real stone paint cannot freely adjust the color and batches of colored sand because of its non-renewable colored sand resources. Instability is not in line with the sustainable development of the country; oil-in-water multi-color paints are gradually eliminated due to their high content of volatile organic compounds, which have huge side effects on the human body. [0003] Water-based colorful paint replaces traditional latex paint with its excellent water resistance, color adjustability, crack resistance, weather resistance and other properties. However, due to the late development of...
