Abstract

The invention discloses a light-weight heat-preservation sound insulating board. The light-weight heat-preservation sound insulating board comprises a basic layer and a surface layer, wherein the surface layer is arranged above the basic layer; a piece of fiberglass cloth is arranged above the surface layer; a piece of fiberglass cloth and a nonwoven fabric are sequentially arranged below the basic layer; the thickness of the surface layer is 0.5mm to 1mm; the overall thickness of the light-weight heat-preservation sound insulating board is 3mm to 40mm; the basic layer comprises the following components in parts by weight: 20 to 30 parts of light calcined magnesia, 40 to 60 parts of magnesium chloride halogen liquid, 12 to 20 parts of saw timber, 2 to 8 parts of modified liquid sodium silicate, 5 to 10 parts of coal ash, and 3 to 6 parts of expanded perlite; and the surface layer comprises the following steps in parts by weight: 18 to 25 parts of light calcined magnesia, 60 to 75 parts of magnesium chloride halogen liquid and 10 to 17 parts of talcum powder. The prepared light-weight heat-preservation sound insulating board is good in heat preservation performance, sound insulation performance and waterproof performance, contains no radioactive element, utilizes wastes and reduces the cost.

Description

technical field [0001] The invention specifically relates to a light heat insulation and sound insulation board. Background technique [0002] Boards are widely used in all walks of life. At present, the existing sound insulation boards are not ideal for thermal insulation, or the thermal insulation effect is acceptable but the sound insulation effect is not ideal. It is impossible to take into account both thermal insulation and sound insulation performances at the same time. Contents of the invention [0003] The object of the present invention is to solve the defects existing in the prior art, and provide a plate with good thermal insulation and sound insulation effects at the same time. [0004] In order to achieve the above purpose, the present invention provides a light heat insulation and sound insulation board, which includes a base layer and a surface layer; the surface layer is arranged above the base layer; a glass fiber cloth is arranged above the surface laye...
