Transparent primer for splint water-based woodware and preparation method thereof

Abstract

The invention discloses a transparent primer for splint water-based woodware and a preparation method thereof. The preparation method comprises the following steps of: adding 75 to 82 parts of polyurethane modified acrylic resin into a dispersing cylinder; adjusting the pH value of the polyurethane modified acrylic resin to 8.0 to 8.5 with stirring; adding 0.3 to 0.5 part of thickener; adding 0.3to 0.5 part of defoamer, 0.3 to 0.6 part of wetting agent and 0.3 to 0.6 part of flatting agent into the mixed materials in turn and then stirring uniformly; adding a mixture of 2 to 4 parts of propylene glycol phenyl ether, 2 to 4 parts of dipropylene glycol methyl ether and 5 to 10 parts of dimethylformamide into the stirred solution; adding 5 to 8 parts of water-based zinc pulp into the mixed solution; and finally regulating viscosity by using 0.5 to 0.8 part of thickener, discharging the obtained product and packaging the product. The transparent primer has high adhesion which can reach 0grade, has a high drying speed and a high rubbing property and can be directly coated on a release agent-containing splint without surface washing, so that work time and washing cost are effectively saved, and environmental pollution can be avoided.

Description

【Technical field】 [0001] The invention relates to the field of wood coatings, in particular to a water-based wood clear primer for plywood and a preparation process thereof. 【technical background】 [0002] Generally, there is a layer of release agent on the plywood, which greatly reduces the adhesion of the paint film on the plywood. The current water-based wood clear primer has been prepared by traditional formula and technology. The adhesion is low, and the paint will fall off with a light tap of your nails. Even if the paint is on the splint, the problem of weak adhesion often occurs. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, to propose a water-based wood clear primer for plywood and its preparation process, which can effectively penetrate into the wood fibers of the plywood and improve the adhesion. [0004] In order to achieve the above object, the patent of the present invention proposes a water-b...
