Abstract

The invention discloses a water-based environment-friendly texture wood coating, which comprises emulsion, pigment, filler, auxiliary agent and water. The invention also discloses a preparation method of the water-based environmental-friendly textured wood coating. It has the following advantages and economic benefits: (1) After construction, the three-dimensional effect is strong, and there will be no collapse or deformation of the shape, and the thick paint film will not crack; No delamination phenomenon; (3) Two kinds of emulsions are used for compounding, which has excellent flexibility, and there will be no cracking problems when matched with primers and topcoats. At the same time, the product has low VOC, low odor, and excellent environmental performance; (4) Different additives are used Thickener matching, low brushing resistance, easy construction, high viscosity and easy spraying roller coating, can adapt to various construction methods of on-site brushing, spraying, and roller coating; (5) It can meet the needs of American antique coating art on wood in the market , has a large market value.

Description

technical field [0001] The invention relates to the field of coatings, specifically, it is mainly used for American-style antique art coating on woodware. It has excellent environmental protection performance, strong three-dimensional shape, thick coating without cracking / excellent adhesion, good flexibility, and can be applied to brushing and spraying at the same time. 1. A water-based environmental-friendly textured wood coating with multiple construction methods of roller coating and a preparation method thereof. [0002] technical background [0003] Textured wood paint, also known as "modeling paint" and "skeleton paint", is a functional special paint for American painting. Textured wood coating is a kind of thick-build coating, which requires good adhesion to the primer and top coat, easy to shape, and no collapse or deformation in shape. The construction method is to use a trowel to spread the textured paint on the surface, and then use a sponge or cotton cloth to pat...
