Background technique

With the development of society and the improvement of people's living standards and the acceleration of urbanization, more and more people live in cities, and the traffic in cities is becoming more and more developed. The noise of vehicles, industrial production, construction and various social life The murmurs combined together seriously affect people's work and sleep. For residents living in the downtown area and beside the road, building sound insulation is particularly important in order to obtain a good living, resting, and office environment. Glass, which is an important part of modern curtain walls, bears the brunt of the impact. The technology generally uses ordinary glass or insulating glass, which cannot achieve the ideal sound insulation effect, and the sound insulation effect needs to be improved.

Patent No. 200620057857.8, High-efficiency sound-insulating glass-utility model, discloses a building material glass that blocks noise pollution, including two upper and lower glass layers that have been roughened, and two PVB (polyvinyl butyral) polymer layers in the middle , There is at least one sound-insulating material layer between the two PVB interlayers, 4mm glass+1.5mmPVB+4mm glass, with a barrier of 40dB. 200820102692.0-A sound-insulating laminated glass for vehicles-utility model, disclosing a sound-insulating laminated glass for vehicles, it relates to a laminated glass, comprising a first glass plate and a second glass plate, characterized in that the two layers There is a sound-insulating film between the plates, the thickness of the first glass plate and the second glass plate is between 1.2-1.6mm, and the total thickness does not exceed 5mm, so it is only suitable for the field of automotive glass. 200820153495.1-Automotive soundproof glass-utility model, disclosing a kind of automobile soundproof glass, which is made of upper and lower layers of automobile glass with the same size and shape, and the middle layer is PVB polymerized soundproof material, which is made by high pressure in a high pressure container. All of the above soundproof glass adopts the middle soundproof film to achieve the effect of soundproofing. The above patents are only suitable for automotive glass. According to the requirements of JGJ102-2003 in the technical specification for glass curtain wall engineering, the glass on the exterior wall of a building must meet the functional requirements of wind pressure resistance, mechanical properties, airtightness, watertightness, heat preservation, and sound insulation. For wall soundproofing.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a sound-insulating glass for buildings with good sound-insulating effect.

In order to achieve the above object, the technical solution adopted by the utility model is:

A kind of soundproof glass for building, comprising outer layer glass, intermediate adhesive layer and inner layer glass, the thickness of the intermediate adhesive layer is 0.76-2.28mm, and metal sound wave reflection layer and absorption layer are sandwiched therein.

The middle bonding layer is a PVB sound-insulating layer, including two layers of PVB boards and a sound-absorbing resin layer sandwiched between them, and metal particles are wrapped in the sound-absorbing resin layer.

The outer layer glass and the inner layer glass are tempered glass, patterned glass, glazed tempered glass, ordinary float glass or heat-strengthened glass, with a thickness of 3-8mm.

It also includes a laminated hollow structure composed of a layer of glass through a sealed adhesive and any layer of glass above.

Beneficial effects of the utility model: for the sound waves of 1000-4000Hz frequency which is the most sensitive to the human ear, the sound-insulating laminated glass can block 5dB on the basis of ordinary laminated glass, and the performance is superior; if the hollow layer is added, the sound-insulating performance can reach 46dB ;Suitable for building sound insulation, especially residential buildings and commercial office places that require sound insulation treatment such as downtown areas, highways, and factories.

Description of drawings

Fig. 1 is a schematic diagram of a sound-insulating glass for buildings according to a preferred embodiment of the present invention.

Detailed ways

Example 1

Referring to Fig. 1, a kind of sound-insulating laminated glass, select 6mm inner and outer glass 1 and 3, PVB sound-insulating layer 2 selects 0.76mm Nippon Sekisui's S-LEC sound-insulating interlayer film, including two PVB boards 21, 23 and middle sound-insulating resin Layer 22, metal particles are wrapped in the sound-insulating resin layer 22 . After the glass is cut, edging, cleaned and tempered, a PVB sound insulation layer is placed in the middle. For flat sound insulation glass, it is rolled by a roller press, and it is heated while rolling to soften the PVB sound insulation layer. The air between the PVB sound insulation layers is well sealed, and then the sound insulation glass is placed vertically in the autoclave, and the finished sound insulation glass is obtained through high temperature (temperature 135-145 degrees, pressure 1.1-1.4MPa) high pressure treatment; for The sound-proof glass with a certain curved surface is pumped by vacuum bag, heated while pumping, so that the glass and PVB are well bonded, and then subjected to autoclave treatment to obtain sound-proof laminated glass. Aiming at the sound wave of 1000-4000Hz frequency which is most sensitive to the human ear, the sound-insulating laminated glass can block another 5dB on the basis of ordinary laminated glass, and the performance is superior.

Example 2

The sound-insulating insulating glass is first made into a sound-insulating laminated glass according to Example 1, and then combined with a piece of glass to make a sound-insulating laminated insulating glass through a hollowing process. As shown in the illustration, an aluminum spacer frame 5 is placed between the outer tempered glass 7 of the insulating glass and the sound-insulating laminated glass. A second sealing layer 4 is arranged between the glass 3, and the glue adopts polysulfide glue. After the hollow glass processing technology, a whole hollow soundproof glass is made.

Structure: 8mm tempered glass + 12mm air layer + (6mm tempered glass + 0.38mm sound insulation PVB + 6mm tempered glass), the sound insulation performance can reach 46dB.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions.
