Abstract

The utility model discloses a metal fiber acoustic board, comprising metal nets, a metal fiber layer, a metal foil and a decorating sprayed coating. The top side and the bottom side of the metal fiber layer are respectively provided with one layer of the metal net; one layer of the metal foil is arranged on the upper surface of the bottom metal net; one layer of the decorating sprayed coating is arranged on the upper surface of the top metal net. The metal fiber acoustic board is formed by that the metal nets spayed with the decorating sprayed coating, the metal net laid with the metal foil and the metal fiber layer which are well arranged are pressed together. The metal fiber acoustic board has the advantages of small thickness, light weight, easy machining, easy installation, favorable sound absorption effect, long service life, easy washing, easy recovery, favorable decorative effect, etc. The metal fiber acoustic board can be used for the sound absorption of indoor walls and roofs, road sound insulation screens and clean workshops, etc., satisfying various modeling needs.

Description

The metallic fiber acoustical board

Technical field

The utility model relates to the noise control technique field, particularly the sound absorption product.

Background technology

The sound absorber that generally adopts is to add that by sound absorption materials such as glass fiber or rock wools the metal sheet mask constitutes at present, the sound absorber that perhaps adopts perforated metal and the cavity that is arranged on its back to form.These two kinds of sound absorber thickness and weight are all bigger, will have heavy cage construction to support during installation, and it is big to occupy the space; When above-mentioned sound absorber is applied in the moulding demand of various variation,, difficulty of processing is increased because the flexibility of metal sheet is poor; Glass fiber or rock wool sound absorption material easily produce dust, cause air pollution, and should not clean, and are not suitable for being applied in clean room; Glass fiber or rock wool have water imbibition, and service time is long can to influence acoustically effective, and can not reclaim and re-use.

The utility model content

The purpose of this utility model provides a kind of metallic fiber acoustical board, this acoustical board have thickness little, in light weight, be easy to that installation and processing, acoustically effective are good, long service life, characteristics such as flushable, recyclable, applied widely.

For achieving the above object, the technical solution adopted in the utility model is: a kind of metallic fiber acoustical board, this acoustical board comprise wire lath, metallic fibrous layer, metal forming and decoration sprayed coating; Described wire lath is two-layer, lay respectively at the top of metallic fibrous layer and below, described metal forming is between metallic fibrous layer and sub-layers of wire mesh, this metal forming is layered on the upper surface of sub-layers of wire mesh, described decoration sprayed coating is sprayed on the upper surface of upper strata wire lath, and double layer of metal net, metallic fibrous layer, the decoration sprayed coating that is layered on the metal forming of sub-layers of wire mesh upper surface and is sprayed on upper strata wire lath upper surface are pressed into the metallic fiber acoustical board up and down.

The thickness of described metallic fiber acoustical board is 1-3mm.

The sprayed on material that described decoration sprayed coating uses is metal or nonmetallic water-based sprayed on material.

The metallic fiber plate that the utility model provides is compared with existing acoustical board, has following beneficial effect:

1. acoustically effective is good

Because the utility model metallic fiber acoustical board adopts metallic fibrous layer, porosity reaches 40%, is that sound absorption material institutes such as perforated metal, glass fiber and rock wool are inaccessible, and low frequency tremendously high frequency noise is all had splendid acoustically effective.

2. thickness is little, in light weight, flexibility is good, plasticity strong, be easy to processing and installation

This metal fiber sound absorption plate can make the thin slice of 1-3mm, does not need heavy cage construction to support during installation, and it is little to occupy the space.Because flexible good, plasticity is strong, bending machining is very easy, and can satisfy the demand of various variable shaping.

3. pollute little, flushable, recyclable, compliance with environmental protection requirements

This metal fiber sound absorption plate is difficult for producing dust, applies on acoustical board even there is dust to be stained with, also available clear water flushing, pollution abatement in time.Because the metallic fiber acoustical board is made of metal, can 100% recycling, can not cause secondary pollution, compliance with environmental protection requirements.

4. long service life

Because the metallic fiber acoustical board has good drainage, can wash laying dust at any time, its acoustically effective can not decayed because of long-time the use, so long service life.

5. good decorating effect

Because the surface of metallic fiber acoustical board has the decoration sprayed coating, can spray into shades of colour, have good decoration effect, and the sprayed on material of this decoration sprayed coating is metal or nonmetallic water-based sprayed on material, so can not influence acoustically effective.

6. applied widely

Because the metallic fiber acoustical board has above-mentioned advantage, make the applied widely of it, can be applicable to the sound absorption of indoor wall and roof, road noise barrier etc., particularly since this acoustical board pollute little, should clean, suit to be applied in clean room, recording room and other particular field sound absorption.

Description of drawings

Fig. 1 is a metallic fiber acoustical board schematic perspective view;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2, aluminum filament is arranged in the aluminum fiber layer 2 that thickness is 2mm, upper and lower surface at this layer is placed aluminium net 1 respectively, at the upper surface shop of lower floor's aluminium net 1 one deck aluminium foil 3, water-based at the upper surface of upper strata aluminium net 1 spraying one deck 0.5mm is decorated sprayed coating 4, with press above-mentioned aluminium net 1, aluminum fiber layer 2 is pressed into the aluminum fiber acoustic board that thickness is 3mm by order shown in Figure 2.

Above-mentioned aluminium material can also be transformed into metal materials such as stainless steel, copper.

Bend to the metallic fiber acoustical board of making cylindric, laterally or vertically be installed on the ceiling, can play the effect that not only absorbs sound but also decoration function is arranged, the metal acoustical board can also be made multiple geometries such as triangularity, trapezoidal, rectangle, rhombus, polygonal, to adapt to different occasions and requirements of different users.
