Abstract

The invention aims at solving the defect of being incendive in the existing acoustic board and discloses a flame retarding acoustic board, which comprises a board material body and plastic supporting structure that is inserted into the board material body; wherein, the board material body is prepared by a flame retarding polymer material which comprises the following components by weight percentage: 69.953 to 95.97 percent of methyl methacrylate monomer, 3 to 30 percent of fire retarding agents, 0.007 to 0.03 percent of evocating agents, 0.02 to 0.5 percent of ultraviolet radiation absorbent and 0.02 to 0.5 percent of hindered amine light stabilizer. The preparation method of the flame retardant acoustic board comprises the steps of preparing the flame retardant polymer material, surface treatment of the plastic supporting structure, mold preparation and casting molding process. The flame retardant acoustic board of the invention can not only meet the requirements of the acoustic board, but also have the function of being flame retardant; in addition, the preparation method of the invention not only has simple operation and is easy for industrial application, but also has low cost and environmental friendliness.

Description

technical field [0001] The invention relates to a sound insulation board, in particular to a flame-retardant sound insulation board. Background technique [0002] With the continuous improvement of living standards, people's requirements for living environment are getting higher and higher, and the problem of noise pollution has gradually been paid attention to by people. The development of the city has brought roads extending in all directions, and the means of transportation are convenient for travel. At the same time, it has also brought serious noise pollution problems. More and more roads are designed and installed with sound insulation blocking systems. Among the many sound insulation board materials, acrylic material is better than PC material in aging resistance, better than tempered glass in impact resistance, and its fully transparent material reduces the driver's visual fatigue, so it has been Highly respected by people in the industry. However, acrylic material...
