Abstract

The invention discloses an aqueous expansion-preventing transparent primer of a medium-density fiber board as well as a preparation method and application thereof. The aqueous expansion-preventing transparent primer of the medium-density fiber board is prepared from 65-70 parts of aqueous acrylic resin, 15-16 parts of aqueous expansion-preventing resin, 0.5-1.5 parts of grinding auxiliary agent, 2-2.5 parts of film-forming auxiliary agent, 0.1-0.5 part of flatting agent, 0.3-0.8 part of defoaming agent, 0.5-0.8 part of thickening agent and 10.4-11.6 parts of water. By using the aqueous expansion-preventing transparent primer of the medium-density fiber board, the drying and grinding performances are guaranteed, and the expansion phenomenon is not generated after the aqueous expansion-preventing transparent primer is coated on the medium-density fiber board; the aqueous primer is safe and environmentally-friendly, and has efficient sealing performance; and the expansion effect of the wood fiber is eliminated by just requiring one working procedure of spray-coating the aqueous expansion-preventing transparent primer of the medium-density fiber board during the primer treatment of the medium-density fiber board, thus the working procedure is simplified, and the efficiency of grinding personnel is improved.

Description

technical field [0001] The invention relates to a water-based anti-swelling tendon transparent primer for medium-density fiberboards and a preparation method and application thereof. The primer can be used for bottom coating of medium-density fiberboards. Background technique [0002] Wood swelling, or wood grain protrusion, is a common phenomenon in water-based wood paint coating. The mechanism of wood swelling is: wood needs to be cut and sharply cut during processing, which will inevitably cut or destroy wood fibers. Integrity, when the fibers of the wood are exposed, the wood fibers act like straws, drawing moisture into the wood, causing the wood fibers to swell and protrude from the wood surface. [0003] Medium density fiberboard (hereinafter referred to as medium density fiberboard) is a man-made board made of wood fiber or other plant fiber, which is crushed, fiber separated, dried, and then added with an applicable adhesive, and then hot-pressed. Therefore, the su...
