Metal composite sound insulation plate and processing technology thereof

Abstract

The invention discloses a metal composite sound insulation plate and a processing technology thereof. The metal composite sound insulation plate comprises a sound insulation layer and a color steel plate. The color steel plate comprises a first side plate body and a second side plate body. The sound insulation layer is wrapped between the first side plate body and the second side plate body. A first side plate inserting block is arranged at one end of the first side plate body, a first side plate groove is formed in the other end of the first side plate body, and the first side plate inserting block can be inserted into the first side plate groove. A second side plate inserting block is arranged at one end of the second side plate body, a second side plate groove is formed in the other end of the second side plate body, and the second side plate inserting block can be inserted into the second side plate groove. The metal composite sound insulation plate has the beneficial effects that the sound insulation layer is made of polyurethane, so that good fireproof performance and waterproof and damp-proof performance are achieved; the sound insulation layer is provided with reinforcing bars, so that the reinforcing effect is achieved, and firm performance is good; through matching of the first side plate inserting block and the first side plate groove which are formed at the first side plate body, and matching of the second side plate inserting block and the second side plate groove which are formed in the second side plate body, convenient mounting is achieved; in addition, a positioning function is achieved; and sealants are smeared after mounting, so that sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a metal composite sound insulation board and its processing technology. Background technique [0002] Sound is a wave-like energy that requires a medium to travel. When sound propagates in the same medium, the denser the medium, the faster the propagation speed. For example, the propagation speed in air at normal temperature is about 340 m / s, and the propagation speed in railroad tracks is about 5200 m / s. [0003] Another kind of propagation of sound is the propagation across media. That is to say, from one medium to another medium through the critical contact surface of the two mediums, at this time, the transmission of sound energy is essentially the transmission of vibration amplitude. When propagating across media, the greater the density difference between the two media, the greater the loss of sound energy. In practical applications, air is the normal activit...
