Embodiment 1

[0022] The first is the preparation of the decorative surface layer. Weigh a certain amount (the formula is weighed according to the composition) of MgSO4.7H2O, lightly burned MgO powder, inorganic pigments, colored sand and additives, stir evenly, and then spread the slurry evenly. On the template, the thickness is controlled at 3mm, followed by laying alkali-resistant glass fiber mesh cloth; finally, the substrate of the decorative plate is prepared, and MgSO4. On the fiber mesh cloth, the thickness is controlled at 10mm, and it is vibrated and compacted during the laying process to improve the strength. The additives described in the decorative surface include modifiers and defoamers, and the weight percentages of the components of the decorative layer are as follows: 35% MgSO 4. 7H 2 O, 35% lightly burned MgO powder, 2% modifier, 20% colored sand, 5% inorganic pigment and 3% defoamer, the additives include modifier and water reducer, substrate The weight percent of each ...

Embodiment 2

[0025] The first is the preparation of the decorative surface layer. Weigh a certain amount (the formula is weighed according to the composition) of MgSO4.7H2O, lightly burned MgO powder, inorganic pigments, colored sand and additives, stir evenly, and then spread the slurry evenly. On the template, the thickness is controlled at 3mm, followed by laying alkali-resistant glass fiber mesh cloth; finally, the substrate of the decorative plate is prepared, and MgSO4. On the fiber mesh cloth, the thickness is controlled at 10mm, and it is vibrated and compacted during the laying process to improve the strength. Described auxiliary agent comprises modifying agent and defoamer, and the percentage by weight of each composition of decorative layer is as follows: 38% MgSO 4. 7H 2 O, 38% lightly burned MgO powder, 2% modifier, 10% colored sand, 5% inorganic pigment, 5% aluminum sulfate and 2% defoamer. Here, in order to increase the decorative effect of the decorative surface, aluminum...

Abstract

The invention relates to a nature-imitated magnesium oxysulfate decorative plate. The nature-imitated magnesium oxysulfate decorative plate is characterized in that the decorative plate is formed by a substrate layer and a decorative layer; the substrate layer comprises, by weight, 10-35% of MgSO4. 7H2O, 10-35% of light-burned MgO powder, 1-3% of a modifying agent (10 parts), 5-15% of sawdust, 5-15 % of perlite and 1-3% of a water reducer, and the sum of the above components is 100%; and the decorative layer comprises, by weight, 10-38% of MgSO4. 7H2O, 10-38% of light-burned MgO powder, 1-3% of a modifying agent, 5-25% of coloured sand, 2-6% of inorganic pigment and 1-3% of a defoaming agent, and the sum of the above components is 100%. The nature-imitated magnesium oxysulfate decorative plate can take the place of real stone, and the natural resource is saved. The nature-imitated magnesium oxysulfate decorative plate has fireproof and thermal insulation functions, and is light in weight and high in intensity. The nature-imitated magnesium oxysulfate decorative plate can be constructed on the wall easily, wet combining and dry hanging construction modes can be employed, and the nature-imitated magnesium oxysulfate decorative plate can be used for interior and exterior wall decoration of buildings.

Description

technical field [0001] The invention relates to the technical field of decorative boards, in particular to a decorative board imitating natural magnesium oxysulfide and a manufacturing method thereof. Background technique [0002] At present, as a new type of cementitious material, magnesium oxysulfide has the characteristics of high strength, non-halogenated, and light weight compared with other cementitious materials. Now some companies have used magnesium oxysulfide materials to prepare fireproof boards. These boards are decorative substrates, and their decorative effects need to be veneered. Most of the decorative surfaces of these boards are organic materials, and their fire resistance and durability are poor. However, the decorative effect of these plates is not natural and ecological. There are also companies that use white Portland cement to prepare imitation natural boards, but this board does not have the functions of fire prevention and light weight, and it does ...
