Embodiment 1

[0027] Such as figure 1 As shown, a new type of magnesium board is composed of four layers, namely: the first layer is the upper non-woven reinforcement layer 1, the main function is to make the surface smooth and convenient for later processing; the second and fourth layers are respectively The upper glass fiber mesh reinforcement layer 2 and the lower glass fiber mesh reinforcement layer 4 are mainly used to enhance the compressive strength and bending strength, and improve the flame retardant performance; the third layer is composed of organic compound adhesive and wood flour magnesium cementitious material Layer 3, which is located at the position of the middle layer, is used as the base layer. The cementitious material composed mainly of magnesium chloride, magnesium oxide, wood flour and polyvinyl alcohol is compounded. The weight ratio of the cementitious material in this embodiment is: wood flour 100-140kg, lithopone 20-30kg, perlite 25~30kg, magnesium chloride 250...

Embodiment 2

[0029] Such as figure 2 As shown, embodiment two is the same as the first to fourth layer structures of embodiment one, and the difference with embodiment one is that a fifth layer is added under the fourth layer of glass fiber mesh reinforcement layer 4, namely The lower non-woven reinforcing layer 5 .

Embodiment 3

[0031] Such as image 3 As shown, this embodiment is the same as the first to fifth layer structures of the second embodiment, and the difference from the second embodiment is that a decorative layer 6 is provided on the surface of the non-woven reinforcement layer 1 on the first layer. In the example, the decorative layer 6 is made of natural wood veneer.

Abstract

The invention discloses a novel magnesian board comprising a multi-layer composite decorative plate formed by interlayer composite of a non-woven fabrics enhancement layer, a glass fiber screen cloth enhancement layer, an organic compound adhesive and a wood powder magnesian gelling material composite layer; the novel magnesian board is good in intensity, fireproof, waterproof, heat-proof, soundproof, and environmental protection; the novel magnesian board is drillable, can be planed, and can be sewed like wood plates; the non-woven fabrics enhancement layer enables the surface to be flatter, so the board is high in intensity, good in toughness, hard to broken, and the non-woven fabrics layer is convenient for late stage processing; the novel magnesian board can solve the problems that existing wood material is not fireproof, and poor in plasterboard intensity; the novel magnesian board can replace wood material, plasterboard, asbestos board and plastic sheet material, and is suitable for indoor / outdoor decoration of various modern buildings.

Description

technical field [0001] The invention relates to a novel environmentally friendly decorative board, in particular to a novel magnesium board. Background technique [0002] At present, the materials that people adopt for the decoration of buildings are mainly blockboard, plywood, density board, particle board, gypsum board and the like. Although wooden materials have a long history as decoration materials and have many advantages, their fatal shortcoming is that they cannot be fireproof, moisture-proof and water-resistant. However, gypsum board is easily broken, difficult to process, and has poor fire resistance. How to make the existing decorative panels fire-proof, moisture-proof, water-resistant, and easy to process is a difficult point to be solved urgently in the industry at present. [0003] In order to solve the above problems, China's 200710025930.2 patent application discloses a "glass fiber felt magnesia board", which uses magnesium oxychloride cement as the main m...
