Abstract
The invention discloses a composite broadband sound absorption insulation plate which is composed of sound absorption coatings, a glass fiber plate, a porous plate and a cavity. The composite broadband sound absorption insulation plate is characterized by being composed of four layers of structures which refer to the sound absorption coatings at the outmost layer, the glass fiber plate, the resin-based porous plate, and the cavity structure at last. The glass fiber plate is of a multi-layer structure which is formed in the mode that the volume weight is gradually increased, and the thicknesses of all the layers of the glass fiber plate are the same. Holes of the porous plate are formed by the fact that before resin-based materials are formed, a foaming agent and high-pressure inert gas of a proper amount are led in under the conditions of pressurization and high temperature so that a large number of holes are formed. The insulation plate formed in this way has the advantages of being light, low in cost, and good in sound absorption performance.
Description
Technical field
The present invention relates to a kind of sound absorption warming plate, particularly relate to a kind of compound broadband band sound absorption warming plate.
Background technology
Along with social development, people are more and more higher for the requirement of constructional materials insulation and sound absorbing capabilities, especially indoor heat-preservation and sound-absorption material requirements is strict especially, not only requirement will possess good insulation, sound absorbing capabilities, also must have both cheapness, attractive in appearance, fire prevention, protection against the tide, dust, many-sided problem such as ageing-resistant.Therefore insulation, the acoustical board of developing a kind of high performance cheapness are extremely urgent.
The Chinese patent of patent No. ZL 200520040761.6 has been announced a kind of mentality of designing of perforated composite decorative sound-absorbing plate, it has solved a difficult problem for lightweight and waterproof aspect, but the wave absorption effect for low frequency and intermediate frequency is not but fine, cannot meet the requirement of broadband sound absorption.And perforated material is placed in to skin, and indoor dust easily enters that this just needs often cleaning among hole, very inconvenient.
The Introduction To Cn Patent of the patent No. 201180034456.4 a kind of heat-preservation and sound-absorption material sheet material, lightweight and broadband sound absorption problem have well been solved, but technique too complex, porous gel gelation and acrylic gel Porous base material surperficial adhere to form and number restive, if well control adhere to form and the number of gel, cost of manufacture is too high again.
Traditional perforated acoustic board has certain selective to sound frequency, sound absorption frequency characteristic is peak shape, and when sound frequency and resonance frequency approach, sound absorption coefficient is large; When sound frequency is during away from resonance frequency, sound absorption coefficient is little, so just cannot meet needs in daily life and absorb the feature that sound frequency is complicated and changeable, also cannot meet the characteristic of insulation.And independent glass fibre cotton felt also cannot meet the absorption requirement for intermediate frequency and low-frequency sound wave, although can increase the absorption for low frequency and intermediate wave by increasing the mode of thickness, but effect is not fine, also can be because the too large impact of thickness is attractive in appearance and increase cost.Thereby can achieve the goal easily by the proportioning of change structure and each composition by compound method design heat-preservation and sound-absorption plate, be the better approach of making insulation, acoustical board.
Summary of the invention
The present invention aims to provide a kind of improved compound broadband band sound absorption warming plate, it possesses lightweight, cheapness and absorbs the wide in range feature of vocal cords, again because sound deadening coating is placed in to most surface, so it does not have because air-borne dust enters the trouble of the frequent cleaning of needs wherein bringing with respect to perforated acoustic board being placed in to outermost sound-absorbing composite board, moreover because the material after compound has advantages of lightweight, so not only reduced its cost of transportation, more alleviated the injury because ornament materials comes off, people being caused in the natural calamity such as earthquake, hurricane.
Technical scheme of the present invention is as follows: a kind of compound broadband band sound absorption warming plate, it is being comprised of with cavity sound deadening coating, glass wool board, microwell plate, and outermost layer is sound deadening coating, is secondly glass wool board, being resin-based microwell plate again, is finally cavity structure; The thickness of sound deadening coating is 0.05～1 millimeter; The multilayer that glass wool board is ascending by unit weight, thickness is identical forms, and the number of plies is 2～8 layers; The aperture of microwell plate is 3～20 microns, and hole is uniformly dispersed and mutually connects; The formation in the hole of microwell plate is by passing into appropriate blowing agent and high-pressure inert gas then forms a large amount of holes under the condition by pressurization, high temperature before resin-based materials moulding.
