Preferably, the vacuum support layer includes two glass plates arranged side by side, a vacuum interlayer is formed between the two glass plates, and a plurality of transverse melt adhesive support strips are arranged in the vacuum interlayer between the two glass plates and a plurality of vertical melt adhesive support bars perpendicular to the transverse melt adhesive support bars, thereby dividing the vacuum interlayer into a plurality of rectangular vacuum domains.

Preferably, the gap of the vacuum interlayer between the two glass plates is 0.1 mm to 0.2 mm.

Preferably, the thicknesses of the first polyurethane foam layer and the second polyurethane foam layer are both 0.5 mm to 1.5 mm.

The utility model has the following advantages:

The utility model is suitable for decorative panels of furniture and ceiling boards of houses, etc., and the indoor and outdoor noise can be absorbed by setting the first polyurethane foam layer and the second polyurethane foam layer to achieve a sound-absorbing effect; on both sides of the first polyurethane foam layer The glass fiber layer and the airgel felt layer are arranged to isolate the first polyurethane foam layer from the outside world. Both the glass fiber layer and the airgel felt layer have good heat insulation and flame retardant advantages, thereby reducing the first The risk of burning when the polyurethane foam layer reaches the ignition point; by setting the vacuum support layer, it not only plays the role of sound-absorbing and flame-retardant, but also serves as a load-bearing carrier for the decorative board; the utility model cooperates with the vacuum support layer as a whole The first polyurethane foam layer and the second polyurethane foam layer form a multi-layered sound-insulating and sound-absorbing structure to ensure the sound-absorbing effect; at the same time, the vacuum support layer cooperates with the glass fiber layer and the airgel felt layer to form a multi-layered heat-insulating and flame-retardant structure to ensure the flame-retardant effect; The algae mud layer is the outermost decorative layer, which can eliminate formaldehyde, purify the air and be beautiful.

detailed description

The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figures 1 to 3, a new type of sound-absorbing and flame-retardant diatom mud decorative board includes a vacuum support layer 7, and a non-woven fabric layer 1 is arranged on the vacuum support layer 7, and the non-woven fabric layer 1 A glass fiber layer 2 is arranged on the top, and the side of the glass fiber layer 2 facing away from the non-woven fabric layer 1 is provided with a porous honeycomb first polyurethane foam layer 3, and the first polyurethane foam layer 3 faces away from the glass fiber One side of the layer 2 is provided with an airgel felt layer 4, and the side of the airgel felt layer 4 facing away from the first polyurethane foam layer 3 is provided with a second polyurethane foam layer 5, and the second polyurethane foam layer A plurality of conical countersunk holes 51 are distributed on the upper surface of the 5, and the side of the second polyurethane foam layer 5 facing away from the airgel felt layer 4 is coated with a diatom mud layer 6.

The utility model is suitable for decorative panels of furniture and ceiling panels of houses, etc. The vacuum support layer cooperates with the first polyurethane foam layer and the second polyurethane foam layer to form a multi-layer sound-insulating and sound-absorbing structure to ensure the sound-absorbing effect; at the same time, the vacuum support layer cooperates with the glass fiber layer, The airgel felt layer forms a multi-layer heat-insulating and flame-retardant structure to ensure the flame-retardant effect; the diatom mud layer is the outermost decorative layer, which can eliminate formaldehyde, purify the air and be beautiful. A plurality of conical countersunk holes 51 are distributed on the upper surface of the second polyurethane foam layer, which can enhance the adhesion of the diatom mud layer 6 and prevent the diatom mud layer 6 from peeling off.

On the basis of the above technical solution, the vacuum support layer 7 includes two glass plates 71 arranged side by side, a vacuum interlayer is formed between the two glass plates 71, and a vacuum interlayer is arranged between the two glass plates 71. There are a plurality of horizontal melt glue support strips 72 and a plurality of longitudinal melt glue support strips 73 perpendicular to the transverse melt glue support strips 72 , thereby dividing the vacuum interlayer into a plurality of rectangular vacuum domains 74 . In this way, the two glass plates 71 can be supported by setting the horizontal melt adhesive support strip 72 and the vertical melt adhesive support strip 73. At the same time, when the diatom mud decorative board is used, the decorative board needs to be cut according to the actual use size When specifically cutting, the horizontal melt adhesive support strip 72 and the longitudinal melt adhesive support strip 73 of the required size position are cut, and the remaining uncut horizontal melt adhesive support strips 72 and longitudinal melt adhesive support strips 73 can still maintain the other parts in the vacuum interlayer. The airtightness of the rectangular vacuum domain 74 not only satisfies the requirement of cutting according to the usage size, but also meets the requirement of ensuring the vacuum rate. When the vacuum support layer 7 is manufactured, it needs to be in a vacuum environment. Hot-melt adhesive is coated on the glass plates 71 , and the two glass plates 71 are attached at high temperature to form a plurality of rectangular vacuum domains 74 .

On the basis of the above technical solution, the gap of the vacuum interlayer between the two glass plates 71 is 0.1 mm to 0.2 mm. Such setting can meet the heat conduction and sound insulation requirements of the diatom mud decorative board, and ensure flame retardancy and sound insulation.

On the basis of the above technical solution, the thicknesses of the first polyurethane foam layer 3 and the second polyurethane foam layer 5 are both 0.5 mm to 1.5 mm. This setting meets the sound insulation requirements and meets the needs of actual use.
