Roller painting water paint and preparation method and use method thereof

Abstract

The invention discloses roller painting water paint and a preparation method and a use method thereof. The roller painting water paint is prepared from water-based propylene-modified alcohol resin, water-based alkyd resin, a cosolvent, a drier, a neutralizer, deionized water, a dispersing wetting agent, a defoaming agent, titanium dioxide, functional filler, a flash-rust inhibitor, a thickening agent and an anti-settling agent. the water-based resin system is selected, VOC is smaller than or equal to 70 g / L, and the paint is basically odorless, environmentally friendly and healthy; the water-based acrylic modified resin is selected, so that the paint film drying speed is high; magnesium lithium silicate is selected as an anti-settling agent and forms a card grid structure when being mixed with water, so that precipitation is prevented, and the uniformity of the water paint is ensured; EDW750, RM-8W and EDW720 thickeners are selected as thickeners with high-shear, medium-shear and low-shear effects, the paint film is smooth and free of roller marks under the condition that the paint film is not sagged by matching the thickeners, the decoration performance is ensured, and the roller painting water paint is simple and convenient in preparation process, easy to control and convenient and quick to use, and has relatively high practical production and application value.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a water paint for roller coating and its preparation method and application method. Background technique [0002] In the field of household installations, traditional solvent-based paints contain a large amount of volatile organic compounds, such as benzene, xylene and other harmful substances, which not only affect the health of construction workers, but also pollute the environment and cause waste of resources. With people's increasing requirements for environmental protection and health, as well as the continuous improvement and strengthening of domestic and foreign environmental protection laws and regulations, the water-based solvent-based paint has become a major trend and has been recognized by more and more consumers. [0003] When traditional water-based paint is applied to large-scale equipment, because the equipment is often larger in size and the area to be ...

AI Technical Summary

Problems solved by technology

Because water-based coatings use water as a diluent and do not contain highly toxic and highly hazardous organic solvents, the drying speed is fast and the leveling time is short, resulting in poor flatness of the coating film appearance; There are often roll marks at the end, which affects the aesthetics
