Embodiment 1

[0018] One, take each component of following parts by weight;

[0019] 30 parts of expanded perlite, 20 parts of polystyrene beads, 30 parts of water glass,

[0020] 5 parts of glass fiber, 5 parts of zinc borate, 10 parts of lime powder.

[0021] Second, carry out the following processing:

[0022] (1) Select expanded perlite of the same chromaticity to be ball-milled with a ball mill, and make the particle size of the particles 0.1-0.19mm, or 1.1-3mm; through a large number of experiments selected from the prior art, it has been proved that when the pearl When the rock particle size is within this range, the mixing of perlite and other components can achieve the best sound-absorbing particle size.

Abstract

The invention relates to a sound absorption plate with fireproof and heat insulation functions, which is characterized by comprising the following ingredients in parts by weight: 30 to 50 parts of expanded perlite, 20 to 30 parts of polystyrene pearl particles, 30 to 50 parts of water glass, 5 to 10 parts of glass fiber, 5 to 10 parts of zinc borate and 10 to 20 parts of lime powder. The sound absorption plate is prepared through procedures of ball milling, stirring, pressing and the like. The sound absorption plate has the advantages of heat insulation, thermal isolation, fireproof and waterproof effects, sound absorption, heat insulation, low cost and attractive appearance and is convenient to install.

Description

technical field [0001] The invention relates to a sound-absorbing board with functions of fire prevention and heat preservation, and belongs to the field of building materials. Background technique [0002] At present, the main method of making sound-absorbing panels with expanded perlite is cement as gel, adding [0003] Appropriate amount of coagulation-promoting material, formed by molding, curing, and natural drying; water glass can be used as a gel [0004] The material is coagulated with sodium fluorosilicate, and it is shaped, dried naturally, or dried in a closed room to adjust the pore drying; organic glue is also used as the gel material, and it is manufactured by a method similar to water glass as the gel material. [0005] The board prepared by the above method has poor fireproof performance, poor sound insulation effect and no heat preservation function, and the cost is high. Contents of the invention [0006] The purpose of the present invention is to provi...
