Problems solved by technology

However, the fatal disadvantage of wood is that it is flammable, so if wood is used as a decoration material in a large area, there will be hidden dangers in fire protection
Especially for buildings with high fire protection level requirements, the decoration method using a large amount of wood does not meet the fire protection requirements
Moreover, due to the dwindling of virgin forest resources, the growth cycle of wood is longer, and the price of pure wood products is rising day by day, the use of a large number of wood for decoration will undoubtedly increase the cost of decoration.
[0003] At present, composite decorative materials have begun to be used in various places for decoration, such as pasting decorative paper on wooden substrates, etc., but this type of decorative material has the disadvantages of low fire rating and low strength.
There is also a decorative material that pastes various decorative papers on the ceramic substrate, but its toughness is not good and it is easily broken.

Embodiment 1

[0024] The composite process of veneer and gypsum board surface includes the following steps:

[0025] 1. Preparation of veneer

[0026] Use round wood or square wood to cut it out with a woodworking planer. The thickness is 0.1mm, and the length and width are determined according to the products produced; the moisture content of the veneer is controlled below 12%; the veneer used is hemlock, cloud One of the veneers of fir, walnut, cherry, toon, and beech.

[0027] 2. Surface treatment of gypsum board and veneer

[0028] Treat the surface of the gypsum board by grinding it with emery cloth to increase its roughness until it feels slightly rough to the touch, and do not over-grind; gently blow the rough surface of the gypsum board with hot air; also clean the adhesive surface of the veneer;

[0029] 3. Glue

[0030] Apply glue evenly on the rough surface of the gypsum board and the glued surface of the wood veneer, the glue amount is 100g / m 2 , the adhesive used is LK-140 ...

Abstract

The invention discloses a surface recombination technology of wood skin and plasterboard, including wood skin preparation, surface treatment of the plasterboard and the wood skin, rubber coating, laminating, painting and other steps. In the invention, the wood skin is pasted on surface of the plasterboard, which can not only embody the special texture of wood and the function of heat insulation and sound attenuation typical of wood, and meet the vision and touch requirements of people, but also improve fire resistance rating of the whole dalle to reach the higher standards for fire fighting materials, as inside of the wood skin is the plasterboard with excellent fire retardancy. In the end, the wood veneer is low in cost, thus the decoration cost is reduced. Through detection, the adhesion strength of the wood skin can reach 0.5MPa.

Description

technical field [0001] The invention relates to a preparation method of a composite building decoration material, in particular to a surface composite process of veneer and gypsum board. Background technique [0002] With the development of society, people are more and more inclined to use materials with natural texture for architectural decoration, and wooden materials have become one of the quite common choices. Wood itself has a warm and natural feel, and it coordinates well with most home furnishing products. However, the fatal disadvantage of wood is that it is flammable, so if wood is used as a decoration material in a large area, there will be hidden dangers in fire protection. Especially for buildings with high fire protection level requirements, the decoration method using a large amount of wood does not meet the fire protection requirements. Moreover, due to the dwindling of virgin forest resources, the growth cycle of wood is longer, and the price of pure wood p...
