Waterborne woodenware primer and preparation method thereof

Abstract

The invention provides a waterborne woodenware primer which is prepared from the following components in parts by weight: 20-30 parts of waterborne acrylic acid resin, 50-60 parts of waterborne core-shell structure self-crosslinking type polyurethane-acrylate resin, 0.1-0.2 part of hydroxyl and amino groups-contained organic amine and 3.8-5.6 parts of additive. For the waterborne woodenware primerprovided by the invention, through combination of three of first layer protection of rapid drying of the waterborne acrylic acid resin, second layer protection of waterborne core-shell structure self-crosslinking type polyurethane-acrylate resin and the hydroxyl and amino groups-contained organic amine, the tension swelling phenomenon occurring after a woodenware prepared from a wood, particularly a soft wood such as a poplar wood and a pine wood is sprayed with a coating for many times can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of primers, in particular to a water-based wood primer and a preparation method thereof. Background technique [0002] As a common material, wood is widely used in construction, furniture and other industries. In daily life, wooden products such as wooden utensils and wooden furniture are very common. In order to improve the beauty of wood products and enhance the performance of anti-corrosion, insect resistance and wear resistance, a layer of water-based paint will be coated on the surface of wood products. Water-based paint is an environmentally friendly paint with water as the dispersion medium. During the installation process, the moisture contained in the water-based paint will enter the interior of the wood fiber of the wood, especially the loose wood such as poplar, pine, etc., which will cause the wood fiber to absorb water and swell, causing the surface of the wood to swell and protrude from the su...
