Problems solved by technology

The main material of polystyrene insulation board is polystyrene. In principle, polystyrene is composed of hydrocarbon elements, and because there is no flame retardant substance on the outer surface of polystyrene insulation board, it is easy to burn and has poor fire resistance. In the event of a fire, it will be heated to produce molten droplets, which has a low safety factor

Abstract

The invention discloses an A-grade fireproof non-combustible polystyrene particle heat insulation board preparation method. The preparation method includes the steps: firstly, weighing components by weight: 80-120 parts of polystyrene foam particles, 300-400 parts of water glass, 400-600 parts of mixed materials and 300-500 parts of water; secondly, sufficiently and uniformly stirring the water glass and the water to prepare into mixed solution A; thirdly, adding the obtained mixed solution A into the mixed materials to sufficiently and uniformly stir to prepare into mixture solution B which is inorganic glue; fourthly, adding the polystyrene foam particles into the obtained mixture solution B to sufficiently and uniformly stir to obtain a mixture C; fifthly, pressing the mixture C obtained in the fourth step by the aid of a pressing die. The A-grade fireproof non-combustible polystyrene particle heat insulation board prepared by the method is high in fire resistance and is not easy to combust and has heat insulation effect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to a method for preparing a Class A fireproof and non-combustible polystyrene particle thermal insulation board. Background technique [0002] Insulation board is a board used as insulation for the exterior wall of a building. In the application of thermal insulation engineering, most of them use organic polymer foam thermal insulation materials, but organic thermal insulation materials have a fatal flaw, that is, they are flammable. For example, polystyrene insulation board is the most widely used in insulation boards. Polystyrene insulation boards are widely used in the field of domestic building insulation due to their low thermal conductivity, high insulation effect, low bulk density, and convenient processability. The main material of polystyrene insulation board is polystyrene. In principle, polystyrene is composed of hydrocarbon elements, and because ther...
