Description
Technical Field
The invention belongs to the technical field of building materials, relates to a solid wood composite floor, and particularly relates to a process for producing a simulated Grice solid wood composite floor and the floor.
Background
The multilayer solid wood composite floor is prepared by coating special paint for the ultraviolet curing floor, which has high performance, high wear resistance and high environmental protection, on a multilayer board made of solid wood veneers with criss-cross textures, wherein the natural rare tree species veneers (veneers) with different thicknesses are used as surface layers, and the multilayer board is used as a base material, and is widely applied to the household building material industry. With the development of society, consumers in the young generation are more concerned about the cost performance, the self-personality promotion and the experience of products, the fashionable appearance of modern people is continuously impacted by the bold and rich tension color matching in the face of the changing demands of the market, the wood floor can not be defined by simple colors or textures any more, and the floor with special surface process and artistic effect becomes a fashion and wave.
At present, the cool tone gradually becomes the hot tone of the ground decoration, the color trend of the home is on the journey of returning to nature, the color of the color system looks like a layer of grey tone without being bloomed and bright, but the color of the color system has high-grade feeling, but the colors are mutually restricted and offset in the whole picture, so that the vision is perfectly balanced.
Glaze is a semitransparent to transparent pigment colorant, is a colorant for wiping, is also called antique paint, is obtained by dissolving resin in a fat-soluble solvent, is slow to dry, has color capable of permeating into pores of wood, is suitable for base materials with deeper textures such as oak, white wax wood, ebony and the like, can be wiped, brushed and has light and shade, can adjust the light and shade depth of the color by wiping, increases the layering sense of the color of a coating film and the definition of wood grains, ensures that the whole color is harmonious, natural and rich in layering sense, and fully shows the advantages of the wood grains; the translucency of the wood can be utilized to reduce the brightness of the board, so that the surface of the wood forms soft contrast, even shadow effect, and classical interest comes from the effect.
The water-based glaze and glaze are the biggest difference between the water-based glaze and the solvent, the water-based glaze (taking an infinite flower as a standard) takes water as a diluent, and the water-based glaze is pure in water property and is green and environment-friendly; the color transparency is extremely high, about three times of oily glaze, and the coating has good wiping property. The paint can be repeatedly wiped during construction, the viscosity cannot be increased, the surface is easy to clean, and the drying time is moderate; the brush is fresh and cool without feeling of brush stagnation; the antique effect is excellent, the stereoscopic impression is strong, and the style is natural; the wood grain conduit is clear and has stable performance. And infinite water-based glaze (colorant) can be used for bottom coloring on UV paint, does not fall off or peel, has excellent adhesive force and good bonding force with UV primer and finish paint.
Chinese patent CN201811650241.5 discloses a floor front glaze process, which comprises a series of process flows of sanding, roller coating special white bottom, manual surface wiping, multiple staged solidification, glaze, manual color wiping and the like, wherein the glaze process is better applied by optimizing the process flows and relevant process parameters, different color repeat feelings are presented on the surface of a product through pure manual coloring and roller coating by a machine, active and young visual impact is brought, and the requirements of young markets are met. Chinese patent CN201821344433.9 discloses a Grace painted wood floor, which is characterized in that a plurality of layers of primer are sequentially painted on the surface of the floor, then a Grace paint layer is painted, and a clean rag is used to wipe off the Gray layer or redundant Gray layer at the later stage until a light and shade contrast layer and an antique effect are wiped off. Chinese patent CN201710093988.4 discloses a UV lacquered wood floor coating process imitating the style of a reinforced board, wherein a polished plain board is coated with white primer and water-based UV primer by roller coating and then subjected to Grice process treatment, and a coating style solid wood floor which is different from the existing wood floor and is suitable for export to Europe, is prepared by adopting a manual color wiping process and has strong heavy color and good stereoscopic impression.
Glaze is a coloring agent for wiping, can fill the color into the pores of wood, can adjust the shade of the color by wiping, increases the layering sense of the color of a coating film and the definition of wood grains, and is indispensable coloring paint for American painting. The special characteristics of the product cater to the psychological needs of people for going to nature and returning to nature, and has good market prospect. But after a lot of roller whites, manual hand wiping is needed immediately, otherwise, the effect is not good after a long time; in addition, manual wiping is more, different techniques and different weights are different, and the effects are different; part of the glaze process needs roller painting water-based, then coloring water-based, then glaze, and then performing hand color wiping treatment, and the process is relatively complex; after partial priming, the glaze layer was applied and wiped.
