Abstract
A glass fiberpolystyreneacoustic board belongs to the technical field of sound insulation boards, and is prepared from polystyrene resin, chopped glass fiber, polyphenyl ether-maleic anhydride, magnesiumalloy micro powder, polyoxyalkylene-polysiloxane copolymer, melamine resin, phosphoric acid, metakaolin, talcum powder, aluminum hydroxide, zinc borate and the like. The manufacturing method comprises the following steps: manufacturing light sound-absorbing particles, a flame-retardant film solution and a fire-resistant glue solution, and then uniformly mixing the raw materials to manufacture a molded plate. The invention has the beneficial effects that polyphenyl ether-maleic anhydride is compatible with polystyrene and glass fiber, a polyoxyalkylene-polysiloxane copolymer is combined with magnesiumalloy particles; after supercritical nitrogen foaming, the porosity can be effectively improved, so that the sound absorption effect can be improved and sound waves can be reduced, the sound attenuation effect can be achieved, and the impact strength and rigidity can be improved. During manufacturing, the light sound-absorbing particles are wrapped by the flame-retardant film liquid and bonded by the fire-resistant glue liquid, and then injection molding is carried out while hot, so that the high-quality glass fiber polystyrene light sound-absorbing board can be manufactured.
Description
technical field [0001] The invention belongs to the technical field of sound-insulating boards, in particular to a glass fiber polystyrene sound-absorbing board. Background technique [0002] With the advancement of technology, the floors are getting higher and higher, and it is inevitable that there will be inter-floor noise between the upstairs and downstairs of the building. [0003] This reduces the comfort of high-rise use. [0004] In order to eliminate floor collision noise, sound-absorbing panels are generally installed on the floors when building apartment buildings. When the collision sound is transmitted through the concrete slab, it is dispersed or absorbed at the floor, thereby preventing the noise from being transmitted between floors. [0005] The existing sound-absorbing panels are based on glass fibers, and their noise reduction coefficient is about 1.0. Sound waves hardly reflect on the surface, which can effectively control and adjust the reverberation ti...
