Firm-type A-grade fireproof polystyrene board and manufacturing method thereof

Abstract

The invention discloses a firm-type A-grade fireproof polystyrene board and a manufacturing method thereof. The firm-type A-grade fireproof polystyrene board comprises a molding foam polystyrene boardand an HMW adsorbent used for modification; and the HMW adsorbent used for the modification is adsorbed in the molding foam polystyrene board. The firm-type A-grade fireproof polystyrene board provided by the invention adopts a bi-directional pressurization production process combining positive and negative pressure, the HMW adsorbent used for the modification enters gaps among molding foam polystyrene board particles to completely isolate and wrap the molding foam polystyrene board particles, so that each particle has excellent flame-retardant smoke-suppressing properties; a honeycomb-shapedstructure formed after the HMW adsorbent used for the modification is solidified with cement slurry has an excellent heat-insulation skeleton function, so that the compressive and tensile resistanceof the molding foam polystyrene board are enhanced; the polystyrene board effectively solves contradiction between heat preservation and fire resistance of a heat-preservation material used for outerwall bodies and a poor firmness defect, has outstanding heat-preservation fireproof effects and good firmness, and improves a safety factor of a heat-preservation system; and the method has a novel production process and high production efficiency.

[0002] Thermal insulation materials used for external walls, thermal insulation and fireproof performance are two hard indicators, especially fireproof indicators, which are related to the safety of people's lives and properties. At present, the thermal insulation and fireproof materials used in the market are mainly divided into organic materials, inorganic materials, organic There are three types of composite materials that are integrated with inorganic compounds. Organic materials such as molded polystyrene boards, polyurethane boards, etc., are characterized by good thermal insulation performance, poor fire resistance, and firmness that meets the requirements; inorganic materials such as rock wool, foamed cement, etc., have characteristics Good fireproof performance and poor heat preservation performance; composite materials such as homogeneous boards, silicon boards, polystyrene boards, etc., are characterized by unstable heat preservation and fire protection performance. Poor performance, thermal insulation, fireproof and solid performance are not compatible. In order to make up for the lack of thermal insulation performance and meet the requirements of thermal insulation and energy saving, inorganic materials and composite materials have to greatly increase the thickness of the material. As a result, the insulation system is easily deformed and falls off, which poses a serious safety hazard
