Color uniformizing process for color shading of solid wood parquets

Abstract

The invention belongs to the technical field of wooden product production, and relates to color uniformizing of solid wood parquets, in particular to a color uniformizing process for the color shading of the solid wood parquets. The color uniformizing process includes the steps of veneering, hot pressing, balance nourishing, cutting, sanding, primer paint spraying, groove and tongue forming, coating and finished product packaging. The four procedures of wetting, bleaching, coloring and color washing are further included between sanding and primer paint spraying. Timber duct notches are adopted for texture positions of the surfaces of the solid wood parquets, water-based primer paint containing color concentrate is brushed into ducts through the mechanical and physical effects, the color of the texture positions is deeper than the color of smooth positions, surface textures of the parquets seem obvious, and the stereoscopic effect is enhanced. According to the disclosed color uniformizing process, before bleaching liquid is subjected to roller painting, by adding the wetting procedure to light-color portions of timber, the bleaching effect of the bleaching liquid on the light-color portions of the timber is slowed down, and the tone of the light-color portions of the timber can be closer to the tone of the deep-color portions of the timber; and by adding the coloring procedure and the bleaching procedure, the overall tone of the timber can be more consistent, the color of the timber can be lighter, and light-color finished products are easy to process.

Description

technical field [0001] The invention belongs to the technical field of wood product production, and relates to the color uniformity of solid wood composite floors, in particular to a technique for uniforming the negative and positive colors of solid wood composite floors. Background technique [0002] In recent years, multi-layer solid wood composite flooring has gradually become a new favorite in the eyes of consumers due to its good stability, diverse and rich surface styles, healthy and environmentally friendly characteristics, and excellent physical and chemical properties. Multi-layer solid wood composite flooring is a tongue-and-groove floor with thin slices of precious wood as the surface layer and multi-layer plywood as the base material. During the growth process of wood, the sapwood and core material will have color difference, which will affect the appearance when used for wood product processing after the wood is grown. In the process of adding wood floors, prop...

Problems solved by technology

The color change treatment is to use a color change agent, and apply the color agent to the lighter part of the wood or the darker part of the color by wiping, but it is mostly manual operation, which is inefficient and not suitable for mechanized production, and will only deepen the color of the wood. It cannot be processed into a light color; treatment with bleach can obviously dilute the wood color, but the effect after treatment is single, there are still obvious boundaries between yin and yang, and the blemishes still exist
