Abstract

The invention discloses an anti-color-infiltration red oak two-component aqueous woodware coating structure, which sequentially comprises a two-component aqueous woodware sealing primer coating, a two-component aqueous woodware burnishing primer coating and a two-component aqueous woodware topcoat coating on a red oak substrate surface, wherein the two-component aqueous woodware sealing primer, the two-component aqueous woodware burnishing primer and the two-component aqueous woodware topcoat respectively comprise a main agent, a curing agent and water. According to the present invention, eachlayer of the structure comprises the two components of the acrylic acid dispersion containing the OH functional group and the aqueous curing agent containing the NCO functional group, wherein the densely-cross-linked structure of the two-component system can barrier and block the pigment tannic acid of the red oak substrate, such that the problem that the infiltration of the tannic acid in red oak can cause the discoloration of the paint coating film can be solved; and the sealing primer coating and the burnishing primer coating have characteristics of strong adhesion and easy burnishing, andthe topcoat coating has characteristics of good smoothness, good flatness, scratch resistance, good paint film hardness and excellent stain resistance.

Description

technical field [0001] The invention belongs to the technical field of wood coatings, in particular to a two-component water-based wood coating structure for anti-seepage color red oak. Background technique [0002] Due to its hard and heavy wood, unique wood grain, good surface treatment characteristics and good machining performance, red oak has become the most ideal material for manufacturing various furniture, floors and cabinets. But red oak contains a lot of tannic acid, tannic acid is a yellow polyphenol compound, the molecule contains a lot of hydroxyl groups, easily soluble in water, ethanol, glycerin, etc., and has the same hydrophilicity as wood, and water is a water-based paint. one of the main components. When the paint is applied to the wood surface, the colored components in the wood will quickly dissolve into the continuous phase of the paint—water, just like adding color to the paint, thus changing the hue of the paint. The seepage of tannic acid will lead...
