Problems solved by technology

However, due to the poor fire performance of polystyrene board, it will produce deadly poisonous gas when it is burned. It has been banned by the relevant state departments, and glass rock wool is used instead of polystyrene board. Although glass rock wool has heat insulation function and A-level fire protection function , but belongs to high energy consumption, high emission, high pollution industries, waste resources, affect the environment, and can not effectively soundproof, not strong enough, harmful to human health at the same time, the safety factor is poor, the scope of application is limited

Abstract

The invention discloses a sound insulation type A-grade fireproof polystyrene board and a preparation method thereof. The sound insulation type A-grade fireproof polystyrene board comprises the following components in parts by mass: 38 to 55 parts of a polystyrene raw material, 38 to 52 parts of fumed silica, 1 to 6 parts of nano-aerogel, 1 to 6 parts of graphene, 1 to 15 parts of white high-temperature ceramic glaze, 5 to 16 parts of gutta-percha, 0.5 to 2 parts of an anti-aging agent AW and 3 to 9 parts of modified sepiolite. Through formula adjustment, the modified polystyrene board which has a heat insulation function, achieves A-grade fire resistance and has an extremely strong sound insulation effect is produced; the compression resistance and tensile strength of the polystyrene board are enhanced, fire safety is improved, and energy conservation and emission reduction are realized; and the sound insulation type A-grade fireproof polystyrene board is low in cost, high in safety coefficient and wide in application range, and has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a sound-insulating A-grade fireproof polystyrene board and a preparation method thereof. Background technique [0002] Polystyrene foam board (referred to as polystyrene board) is widely used in construction and packaging fields due to its low price, excellent thermal insulation performance, and easy processing. However, due to the poor fire performance of polystyrene board, it will produce deadly poisonous gas when it is burned. It has been banned by the relevant state departments, and glass rock wool is used instead of polystyrene board. Although glass rock wool has heat insulation function and A-level fire protection function , but belongs to the high energy consumption, high emission, high pollution industry, wastes resources, affects the environment, and cannot effectively soundproof, is not strong enough, damages human health, and has poor safety factor and limited ...
