Problems solved by technology

Therefore, this method is not only complicated in production and construction process, but also affects the noise reduction effect and fire performance of the sound-absorbing panel.
[0007] Rock wool and glass wool boards are used as sound insulation materials. One of the methods is to directly fix them on the inner wall of the well with nylon nails. Although this method is cheap, the resin will degrade after 3-5 years, or the wind pressure in the well will Under the action of the air, the material will volatilize and fall off. In addition to losing the sound insulation effect, it will also affect the environment. In addition, the droplets produced will aggravate the noise of the elevator.
The second is to use light steel keel, gypsum board or mineral wool sound-absorbing board, and seal rock wool and glass wool sound insulation materials in the wall. Although this method can avoid material falling off, the cost is very high. The price is between 160-220 yuan, and the auxiliary materials such as keel and gypsum board are far more expensive than the main materials, which greatly increases the cost

Embodiment 1

[0046] Embodiment 1: a kind of sound insulation and thermal insulation material, such as figure 1 As shown, it includes a sound-absorbing material body 1 and a surface covering layer 2, the surface covering layer is arranged on the surface of the sound-absorbing material body, and is combined with the sound-absorbing material body through an adhesive.

Embodiment 2

[0047] Embodiment 2: A sound insulation and thermal insulation material, which includes a sound-absorbing material body 1 and a surface covering layer 2, the surface covering layer 2 is arranged on the surface of the sound-absorbing material body 1, and is combined with the sound-absorbing material body through an adhesive. Among them, the sound-absorbing material main body 1 is made of glass fiber needled felt or glass fiber needled board, with a thickness of 10mm-50mm and a density of 60-180kg / m 3 , wherein the glass fibers in the main body of the sound-absorbing material include glass fibers of two different diameters, one is thick glass fibers with a diameter of 12-15 μm, and the other is thin glass fibers with a diameter of 5-10 μm. The weight mixing ratio of glass fiber is 30-70:70-30, and the length of thick glass fiber is 40-80mm, and the length of fine glass fiber is 40-80mm. The combination of disordered and interlaced ways presents an unoriented three-dimensional mi...

Embodiment 3

[0048] Embodiment 3: For the sound insulation and thermal insulation material in Embodiment 2, the thickness of the sound-absorbing material body is 20-30mm, by comparing with 60mm rock wool materials, during the experiment, use glass fiber needle felt or glass fiber needle felt The noise reduction effect of the board is obvious, and its daytime index can reach below 37 decibels, and the nighttime index can reach below 33 decibels.

Abstract

The invention relates to soundproof and insulation materials used in the filed of buildings such as a lift way, an equipment room, garage ceilings, karaoke bars and floor boards, and also relates to a soundproof and insulation layer comprising the material, and a preparation method and application thereof. The soundproof and insulation material comprises a sound-absorbing material main body and a surface coating layer, and the surface coating layer is arranged on the surface of the sound-absorbing material main body and integrated with the sound-absorbing material main body by using adhesives. The soundproof and insulation material can be used for effectively isolating various noises and absorbing various noises conducted through a wall body, the soundproof and insulation material also has a good insulation function, and the application scope is very wide.

Description

technical field [0001] The present invention relates to a sound-insulating and heat-insulating material, a sound-insulating and heat-insulating layer and its preparation method and application, in particular to a sound-insulating and heat-insulating layer used in construction fields such as elevator shafts, machine rooms, pump rooms, garage ceilings, karaoke halls, recording studios, and floors. A sound-insulating and heat-insulating material, a sound-insulating and heat-insulating layer including the sound-insulating and heat-insulating material, a method for manufacturing the sound-insulating and heat-insulating layer, and an application of the sound-insulating and heat-insulating layer in the construction field. Background technique [0002] Noise pollution is becoming more and more prominent in modern society. For example, the noise generated by elevator shafts, machine rooms, pump rooms and garage ceilings often bothers people. [0003] Among them, elevator noise is the...
