Examples

The embodiment of the utility model provides a noise-reducing sound-absorbing fireproof rock wool board which can be applied to building materials with noise-reducing sound-absorbing fireproof effects on the outer vertical surfaces of buildings, and can be applied to the inner wall surfaces of KTV (Karaoke television) rooms to achieve the noise-reducing sound-absorbing fireproof effects.

As shown in fig. 1 to 3, the noise-reducing, sound-absorbing and fireproof rock wool board of the present embodiment is a multi-layer board structure, and includes an outer rock wool layer 1, a flame retardant layer 2, a noise-reducing and sound-absorbing layer 3, and a waterproof layer 4; the outer rock wool layer 1 is arranged on the outermost layer and is sequentially connected with the flame-retardant layer 2, the noise-reducing and sound-absorbing layer 3 and the waterproof layer 4, and a supporting net is arranged outside the noise-reducing and sound-absorbing layer 3 for wrapping.

The noise reduction and sound absorption layer 3 is mostly made of soundproof cotton or a rock wool layer made of natural basalt melted into liquid lava after silking, and the material of the soundproof cotton can be selected from the prior art according to the actual soundproof requirement, which is not described herein. And the selection on rock wool layer then will be the entire body and be by the rock wool fibre that has the elasticity micropore, and when the noise transmitted in the rock wool layer, the vibrations energy of sound wave shuttles back and forth, reflection and friction between the rock wool fibre, and final acoustic energy is converted into heat energy and is consumed totally, consequently arranges rock wool abatvoix at indoor wall or top, when the noise appears in indoor, and the sound wave transmits in to the rock wool layer through decorating the top layer to sound and the syllable-dividing effect have been realized inhaling. Therefore, the noise reduction and sound absorption layer 3 is provided with rock wool fibers with elastic micropores in the whole body. And consider that the material that present has the sound of making an uproar to fall is the material that flexibility or elasticity are great mostly, if directly use this material in the plate body, in processing or use, probably can lead to should making an uproar to fall to inhale the sound deformation because of reasons such as extrusion, and then influence the effect of making an uproar to inhale the sound, so be provided with the supporting network parcel outside the sound absorbing layer 3 that makes an uproar to fall, the supporting network is the metal fiber net or the glass fiber net who wraps up whole sound absorbing layer 3 that makes an uproar, the intensity of supporting network can keep the form of sound absorbing layer 3 that makes an uproar to a certain extent.

The utility model provides a still including the through-hole 5 that is used for the fixed plate body on the rock wool board. Most of rock wool boards in the prior art are directly adhered to a wall body, so that the board body is easily damaged when the rock wool boards need to be replaced or detached. Therefore, set up through-hole 5 on the rock wool board and can be used for fixing the rock wool board to the place that needs the use, be difficult to the damage plate body when dismantling like this. Of course, the number of the through holes 5 can be determined according to actual needs, and when the rock wool board is larger, more through holes 5 can be arranged.

The outer surface of the outer rock wool layer 1 is coated with fireproof paint and the flame-retardant layer 2 is made of fireproof and nonflammable materials such as asbestos. Thus, the fire-retardant coating is coated on the outermost contact surface to cope with a short-time fire with a small amount of fire, and the flame-retardant layer 2 is provided to cope with a fire which is common in daily life.

The whole shape is square, and four corners are respectively provided with a through hole 5. The square plate body is easy to splice and convenient to construct, so that the square of a scene can be adopted as the shape of the rock wool plate.

The waterproof layer 4 is a glass magnesium board layer. The material of the glass magnesium board comprises active high-purity magnesium oxide (MgO), high-quality magnesium chloride (MgCl2), alkali-resistant glass fiber cloth, plant fiber, non-combustible light perlite, chemically stable lithopone, high molecular polymer and high-performance modifier. The fireproof heat-insulating board has good fireproof performance, is a non-combustible board, has zero flame continuous combustion time, does not combust at 800 ℃, has no flame at 1200 ℃, reaches the highest fireproof and non-combustible grade A1, has a fire resistance limit of more than 3 hours with a partition system made of high-quality keels, and can absorb a large amount of heat energy in the process of burning when meeting fire and delay the rise of the ambient temperature. In dry, cold and humid weather, the glass magnesium board has the same performance, is not influenced by condensed water drops and humid air, can not deform and soften even if being soaked in water for a plurality of days and taken out for natural air drying, can be normally used, and never generates the phenomenon of moisture absorption and halogen return.

The outer rock wool layer 1, the flame-retardant layer 2, the noise-reducing and sound-absorbing layer 3 and the waterproof layer 4 are connected through cyanoacrylate or soybean glue.

According to the noise-reducing sound-absorbing fireproof rock wool board, the surface of the outer rock wool layer is coated with fireproof coating, the flame-retardant layer is made of asbestos materials with good fireproof performance, and the glass magnesium board layer with certain fireproof and heat-absorbing performances is selected besides waterproof and moistureproof performances, the fireproof performance of the rock wool board can be improved through the matching of multiple settings, and the noise-reducing sound-absorbing layer is made of soundproof cotton or rock wool fibers with elastic micropores in the whole body to adapt to various situations needing noise reduction and sound absorption.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
