Abstract

The invention discloses a light sound insulation magnesium oxysulfate fireproof material and a preparation method of a wall plate, and mainly relates to the field of building materials. The light sound insulation magnesium oxysulfate fireproof material comprises the following components in parts by weight: 150 parts of magnesium oxide, 100-200 parts of a magnesium sulfate solution, 1-2 parts of amagnesium oxysulfate modifier, 0.1-0.5 part of polypropylene fiber, 10-50 parts of a fireproof adsorption material, 3-12 parts of polystyrene particles, 20-80 parts of a foaming inorganic material, 10-50 parts of an active filler and 5-50 parts of foaming agent foam. The light sound insulation magnesium oxysulfate fireproof material can effectively reduce the density of the wall plate on the basisof the fireproof and flame-retardant function of magnesium oxysulfate cement to achieve the light effect, can generate a porous structure and has sound absorption and sound insulation effects. The added inorganic material can prevent fire and flame.

Description

technical field [0001] The application relates to the field of building materials, in particular to a light-weight sound-insulating magnesium oxysulfide fireproof material and a preparation method of a wall board. Background technique [0002] Wall materials are used in theaters, concert halls, exhibition halls and other places, mainly considering their sound insulation and fire prevention effects. In the existing technology, the sound insulation performance is generally ensured by increasing the thickness and density of the wall, but as the thickness and density of the wall increase, the wall will be overweight, resulting in a greater structural load burden and increased construction difficulty. question. However, if you blindly pursue the light effect by reducing the density of the wall material, and cannot guarantee the fire performance of the wall, it is easy to lose sight of the other. [0003] Therefore, there is a lack of a wall material in the market that has both ...
