Problems solved by technology

[0005] In the traditional preparation method of modified EPS fire-proof insulation board, the gel state of flame-retardant particles is not strictly controlled, and the gelation of EPS particles is easily insufficient or super-gelled during the production process.
If the particle gel is insufficient, the surface of the particle is still partially viscous, and the particle adhesion phenomenon is serious, and it is difficult to realize the pumping of the particle; Consequences of sandwich, loose or no molding at all due to poor bonding activity
[0006] Due to the large amount of flame retardant adhesive used in the production process of A2 grade modified EPS fireproof insulation board, it is almost impossible to realize the molding of A2 grade fireproof foam insulation board when using conventional steam heating molding method. Difficulties in the board making process

Abstract

The invention discloses a thermosetting composite resin foam insulation board and a preparation method thereof. The insulation board is prepared from the following raw materials in parts by weight: 100 parts of pre-foamed and cured EPS (Expandable Polystyrene) particles, 50-2000 parts of fire-proof hybridized adhesive and 5-500 parts of curing agent. The thermosetting composite resin foam insulation board disclosed by the invention achieves the level A2. The thermosetting composite resin foam insulation board prepared by the fire-proof hybridized adhesive has the advantages that the firing surface is carbonized in case of fire, no vertical and horizontal fire spread exists, the self-extinguishing is achieved apart from the fire, no smoldering is generated, no ember dripping and no toxicity are generated, the amount of flue gas is low and the safety is guaranteed, so that level-A2 fire prevention can be truly achieved. The fire-proof hybridized adhesive disclosed by the invention has the advantages of high bonding strength and high toughness and is conductive to the latter thermoforming of particles, and the fire rating of the homogeneous mixed foam insulation board is ensured.

Description

technical field [0001] The invention relates to the technical field of thermal insulation material preparation, in particular to a thermosetting composite resin foam thermal insulation board and a preparation method thereof. Background technique [0002] At present, the EPS insulation material widely used in my country's buildings has good heat insulation and water-repellent properties, mature construction technology, light weight and low price. It is currently the most widely used exterior wall insulation material in the world. However, this kind of insulation board has poor flame retardancy, is easy to catch fire and drips and melts, and has a great fire hazard. The increase in the number of high-rise buildings in major cities across the country and the continuous rise of high-rise buildings have brought great difficulties to fire prevention. Once a fire breaks out, it is very easy to cause heavy casualties, economic and property losses because it cannot be extinguished fr...
