Abstract

The invention relates to a water-based primer, in particular to a water-based conglutination primer for solid-wood products and a preparation method thereof. The water-based conglutination primer is prepared by mixing the following raw materials in percentage by weight: 30 to 65 percent of polyacrylic emulsion, 30 to 65 percent of water, 2 to 5 percent of alcohols-ethers solvent, 1 to 3 percent of thickening agent and 0.5 to 1 percent of defoaming agent, wherein a Tg value of the polyacrylic emulsion is more than or equal to 30 DEG C and less than or equal to 70 DEG C. The water-based conglutination primer is first coated and brushed on the solid-wood products, can permeate through wood fibers and form a continuous dense paint film at a position 1 to 2 mm away from the surface of wood to play a role in sealing, also can completely expand and harden splinters of the wood and the wood fibers on the surface of the wood so as to be favorable for smoothly grinding the wood thorns and the wood fibers, and can effectively prevent the infiltration of water content from causing the expansion of the wood in re-construction due to the continuous dense film below the surface of the wood.

Description

technical field [0001] The invention relates to a water-based primer, in particular to a water-based glue-fixed primer for solid wood products and a preparation method thereof. Background technique [0002] During the water-based coating process of solid wood wood products, solid wood is prone to wood thorns, swelling and other problems. Traditionally, solid wood products and antique colored wood products use solvent-based coatings. The production technology generally uses benzene series, ketones, alcohol ethers, and esters as solvents, nitro or polyurethane as the main film-forming substance, and some fillers and Auxiliary composition. The wood bottom treatment agent produced by this method does not have the problems of splintering and swelling of the wood diameter, but due to the use of the above-mentioned large amount of harmful organic solvents, it has brought harm to the health and the environment of the construction personnel and the final user of the product.
