Problems solved by technology

For a long time, wooden sound-absorbing decorative panels have been widely used because of their good sound-absorbing effect and strong decorative effect. Environmental protection issues such as formaldehyde release in sound panels also restrict the further application and development of this type of material, so a sound-absorbing material that is non-combustible, environmentally friendly, and has good sound-absorbing and decorative effects is urgently needed in the market.

Embodiment 1

[0013] 18% by weight of the slurry and 82% of the solid filler are made into a slurry after being stirred by a mixer at 120 rpm, wherein the slurry consists of 9% by weight of magnesium sulfate, 29% of magnesium oxide, and the balance for water. The solid filler is composed of diatomite, kaolin, coal ash, wollastonite, expanded perlite, conductive china clay powder, conductive mica powder, and reinforcing fibers. Their weight percentages are 10% of diatomite, 30% of kaolin, 10% coal ash, 10% wollastonite, 10% expanded perlite, 10% conductive china clay powder, 10% conductive mica powder, and 10% reinforced fiber. The resulting slurry mixture is extruded to form an embryo body, which has the characteristics of fire resistance, antistatic, waterproof, moisture-proof, moth-proof, mildew-proof, and antibacterial, and then dried at 70°C for 2 hours, and then dried in a natural environment. Cured under conditions for 3 days, and finally cut to form an inorganic material layer; then...

Embodiment 2

[0015] 14% by weight of the slurry and 86% of the solid filler are made into a slurry after being stirred by a mixer at 120 rpm, wherein the slurry consists of 4% by weight of magnesium sulfate, 24% of magnesium oxide, and the balance for water. The solid filler is composed of diatomite, kaolin, coal ash, wollastonite, expanded perlite, conductive china clay powder, conductive mica powder, and reinforcing fibers. Their weight percentages are 15% of diatomite, 20% of kaolin, coal 15% ash, 10% wollastonite, 15% expanded perlite, 15% conductive china clay powder, 5% conductive mica powder, and 5% reinforcing fiber, wherein the reinforcing fiber is made of non-woven fabric. Extrude the prepared slurry mixture into an embryo body by means of counter-rollers, dry it at 75°C for 1 hour, keep it under natural conditions for 5 days, and finally cut it into an inorganic material layer. This inorganic material layer has good fire resistance. It can achieve Class A non-combustibility, an...

Embodiment 3

[0017] 15% by weight of the slurry and 85% of the solid filler are made into a slurry after being stirred by a mixer at 120 rpm, wherein the slurry consists of 6% by weight of magnesium sulfate, 26% of magnesium oxide, and the balance for water. The solid filler is composed of diatomite, kaolin, coal ash, wollastonite, expanded perlite, conductive china clay powder, conductive mica powder, and reinforcing fibers. Their weight percentages are: 10% diatomite, 25% kaolin, coal 10% ash, 20% wollastonite, 15% expanded perlite, 10% conductive china clay powder, 5% conductive mica powder, and 5% reinforcing fiber, wherein the reinforcing fiber is made of non-woven fabric. Extrude the prepared slurry mixture into an embryo body by paired rollers, dry it at 72°C for 1.5 hours, maintain it under natural conditions for 4 days, and finally cut it into an inorganic material layer; then compound it on the upper end of the inorganic material layer PVC is used as a decorative layer, and the ...

Abstract

The fireproof sound absorbing decoration board consists of one facing layer and one inorganic base material layer comprising slurry in 14-18 wt% and solid stuffing in 82-86 wt%. It is produced through adding conducting china clay powder, conducting mica powder, and other conducting material and reinforcing fibrous material into inorganic material as the main material; adhering with inorganic adhesive, naturally curing to form special board, and compounding surface decoration material to reach different decoration effects. Technologically, the fireproof sound absorbing decoration board absorbs sound by means of its porous structure to reach certain sound absorbing effect and its slots and holes to form resonant structure and further sound absorbing effect.

Description

Technical field: [0001] The invention relates to the technical field of decorative panels, in particular to a non-combustible sound-absorbing decorative panel and a manufacturing method thereof. Background technique: [0002] At present, the indoor surfaces of buildings include floors, walls and ceilings. If hard and dense stones, plasters and wooden boards are used for decoration, these materials will strongly reflect sound waves, and the reflected sound will strengthen the indoor sound and cause The reverberation time in the room is very long. In this kind of room for meetings, classes or performances, although the audience feels the sound is very loud, they only hear a very unclear rumbling sound. Therefore, sound-absorbing decoration is generally required indoors, especially the sound effect of concert halls, theaters, cinemas, dance halls, recording studios and other buildings is also very important. If no sound-absorbing decoration is done, it will form an annoying no...
