Abstract

Water-based woodenware seal primer and a preparing method thereof are disclosed. The seal primer comprises components in a certain ratio. The method includes adding an acrylic emulsion, a silane coupling agent, a nanometer enhancer, a coalescing agent, a defoaming agent, a leveling agent, a thickening agent and a pH conditioner in order, stirring, filtering and packaging. The seal primer is high in permeability and excellent in sealing performance, and is capable of penetrating into the inside of wood, blocking capillary pores on the surfaces of the wood, allowing the amount of open pores on the surfaces of the wood to be reduced, and making the sealed pores increased, thus inhibiting penetration of water in top paint into a base material so as to achieve excellent anti-expansion effects. A unique paint film enhancing technology is adopted, so that paint film is dried rapidly to achieve film formation. Compact honeycombed paint film is formed on the base material, and tannic acid and grease in the wood are prevented from penetrating to the surface of the paint film, thus achieving anti-expansion and grease-sealing effects.

Description

technical field [0001] The invention relates to a water-based primer, in particular to a water-based wood sealing primer and a preparation method thereof. Background technique [0002] Due to the unique looseness of wood, such as pine wood and medium density fiberboard absorb moisture, wood fibers are easy to swell, and tannins and oils in solid wood can easily penetrate into the surface of the paint film, making the paint film yellow or spit out oil. These are common problems in the construction of water-based wood lacquers, and it is difficult for the water-based wood sealing primers on the market to solve the above problems. In order to solve the problems of solid wood swelling and MDF swelling, fatty wood oil precipitation and tannic acid penetration, the present invention provides a high-performance water-based wood sealing primer, which can inhibit the penetration of water in the upper coating to the substrate, It can also prevent the tannic acid and oil in the wood f...
