Abstract

The invention relates to the field of a water-based paint, and specifically relates to a water-based sand-textured paint. The water-based sand-textured paint comprises the following components in percent by weight: 30-50 percent of acrylic acid modified water-based polyurethane, 10-20 percent of water-based epoxy resin, 2-5 percent of pigments, 3-8 percent of non-fluorine sand-textured powder, 1-2 percent of a polyacrylate flatting agent, 4-8 percent of an adhesive-force accelerant, 3-8 percent of a dispensing agent, 1-2 percent of a thickening agent and the balance water. The water-based sand-textured paint disclosed by the invention has good adhesive force and compatibility, and helps to fully eliminate delamination phenomenon appearing between a new coating layer and a preceding sand-textured coating layer when the surface of the sand texture appears quality defects and needs to be coated again.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a water-based sand texture paint and a preparation method thereof. Background technique [0002] Sand texture paint means that it does not have the luster of ordinary paint after spraying, and it has a matte texture to the touch, providing a variety of coating effects for furniture. Solvents, additives, these solvents and additives contain a large amount of volatile organic compounds (VOC), and pollute the environment, damage the health of painters, are flammable and explosive, and waste petroleum resources, which has brought great harm to the preparation and use of frosted paint. great inconvenience and potential harm. [0003] With the progress of society and the development of petrochemical technology, the types of coatings are gradually changing to green and environmentally friendly, and some new coatings are gradually developed and favored by enterprises. Especially the wa...
