Description

Sound-insulation gypsum board

Technical Field

The utility model relates to a gypsum board technical field, in particular to gypsum board gives sound insulation.

Background

The gypsum board is a material prepared by taking building gypsum as a main raw material, is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation, fire prevention and other performances, is one of novel light boards which are intensively developed at present, is widely used for inner partition walls, wall covering panels, ceilings, acoustic panels, ground base boards, various decorative boards and the like of various buildings such as houses, office buildings, shops, hotels, industrial factory buildings and the like, is used for indoor installation in bathrooms or kitchens, and is mainly prepared by the following steps: the sound-insulating board is a board which acts on sound-insulating effect, and has building sound-insulating and building sound-insulating classification, the sound-insulating board can not block sound of all frequencies, the object has inherent resonance frequency, sound close to the object resonance frequency, the sound-insulating effect of the sound-insulating board is obviously reduced, the sound-insulating board has the difference between air sound and vibration sound, the air sound-insulating board is a board which blocks sound transmitted in the air, the vibration sound-insulating board is a board and a system which blocks sound transmitted in a rigid member, and the general object has the sound-insulating effect, but the board with the average sound-insulating quantity exceeding 30dB is called the sound-insulating board, the sound-insulating board is generally a low-density material, the sound is wave energy, the medium is needed to transmit, when sound is transmitted in the same medium, the higher the density of the medium is, the faster the transmission speed is, for example, the transmission speed in normal temperature air is about 340 m/s, the transmission speed in a rail is about 5200 m/s, and the other transmission of sound is cross-medium transmission, namely, from one medium, through the critical contact surface of the two media and into the other medium, at this time, the transmission of sound energy is essentially the transmission of vibration amplitude, and when the density difference of the two media is larger when the sound is transmitted through the medium, the larger the loss of sound energy is. In practical application, air is a space which is moved by human beings in a normal state, so that a material with a larger density difference with air is generally a material with a high density, namely the material can be regarded as a sound insulation material, and the higher the density is, the better the sound insulation effect is. The boards made of the material are called sound insulation boards, are classified according to the category of civil engineering, and can be divided into two types of sound insulation of buildings and sound insulation of structures; the sound insulation is classified into two categories, i.e., indoor sound insulation and outdoor sound insulation, according to the sound insulation position, and for example, the indoor sound insulation includes: the sound insulation of walls, construction surfaces, ceilings, other characteristic construction surfaces needing sound insulation and underground buildings is also an input indoor sound insulation part; the main outdoor sound insulation items include sound insulation of an open wall and other outdoor sound insulation items; the sound insulation board is generally composed of three layers, the upper layer and the lower layer are gypsum boards, and the middle layer is a split material with larger density difference as a sound insulation split material, generally the gypsum board is made of sound insulation cotton; there is certain drawback when using in current syllable-dividing gypsum board, and the soundproof cotton that traditional syllable-dividing gypsum board's centre was used can receive the extrusion at the in-process of transportation, takes place to warp, influences syllable-dividing effect, and soundproof cotton is difficult to glue and glues and drop easily, when adopting the mode of pasting installation acoustic celotex board, and the surface is too smooth, is difficult to paste, for this reason, we propose a syllable-dividing gypsum board.
