Problems solved by technology

[0004] The above-mentioned prior art uses glass fiber mesh cloth as a reinforcing material, and glass fiber mesh cloth has excellent toughness, so that when the glass fiber mesh cloth is combined with other materials, the internal bonding strength is low; When the mortise is installed, the mortise of the glass magnesium board is easily peeled off by the shear force, resulting in the cracking of the notch of the mortise, which affects the practicability of the glass magnesium board

Embodiment 8

[0098] Example 8, a high-whiteness MGO decorative board includes a surface layer and a substrate, and marble is used as the surface layer. The MGO substrate prepared according to the above-mentioned embodiment 2 is bonded on the cut marble plane through a polyurethane adhesive, and cured after 15 minutes. time, and then the marble is connected to the MGO substrate and cut open to obtain a marble surface composited with the MGO substrate. Whiteness MGO trim board.

Embodiment 9

[0099] Example 9, a high-whiteness MGO decorative board includes a surface layer and a substrate, boxwood veneer is used as the surface layer, and the MGO substrate prepared according to the above-mentioned embodiment 2 is bonded on the plane of the veneer by a polyurethane adhesive, after 15 minutes of curing time , to get a semi-finished product; then the semi-finished product is subjected to sanding, UV or UV after coloring, cutting, and grooving to obtain a high-whiteness MGO decorative board.

Abstract

The invention discloses a high-whiteness MGO substrate, a preparation method and a decorative plate with the substrate. A high-whiteness MGO substrate includes a surface layer and a substrate, and the substrate is composed of a forming agent, a lightweight filler, a modifier and water, and the parts by mass of each component are as follows: 40-49 parts of light-burned magnesium oxide powder, seven 18-25 parts of magnesium sulfate water, 16-25 parts of polyvinyl alcohol solution, 16-20 parts of plant powder, 0.5-2 parts of modifier; the modifier is citric acid: phosphoric acid: sodium sulfate by mass ratio The ratio of 10:3:6 is mixed; it has the advantages of high internal bonding strength and is not easy to peel and crack; the preparation method of this substrate has the advantages of simple preparation process, effectively improving the internal bonding strength of the substrate, and not easy to peel and crack; the decorative board It has the advantages of wide application range and good practicability.

Description

technical field [0001] The invention relates to the field of decorative materials, more specifically, it relates to a high-whiteness MGO substrate, a preparation method and a decorative plate with the substrate. Background technique [0002] Glass magnesium fireproof board is also called glass magnesium board, magnesium oxide board, magnesite board, and magnesium board. The material components for the production of glass magnesium fireproof boards are active high-purity magnesium oxide (MgO), high-quality magnesium chloride (MgCl 2 ), alkali-resistant glass fiber cloth, plant fiber, non-combustible light perlite, chemically stable lithopone, high molecular polymer, high-performance modifier, made by mechanical rolling, mainly used for indoor non-bearing walls and Suspended ceilings, and substrates for various decorative panels. [0003] At present, the Chinese invention patent with the authorized announcement number CN101871246B discloses a glass magnesium board, which is ...
