Abstract

The invention discloses a fire-proof adhesive and application thereof. The fire-proof adhesive comprises the following components by parts: 100 parts of high-temperature bonding agent, 10-70 parts of fire retardant, 0.5-50 parts of flame retardant synergist, 5-50 parts of strength enhancer, 0.05-20.0 parts of water-proof modifying agent and 0.01-2.0 parts of curing modifying agent. By adopting the fire-proof adhesive and a preparation method of a fire-retardant EPS (Expandable Polystyrene) foam heat-insulating plate, the combustion performance and physicochemical performance of the fire-retardant EPS foam heat-insulating plate can be improved remarkably. For example, the heat-conducting coefficient can be lowered below 0.055w/m.k, the specific gravity can be lower than 150Kg/M<3>, the compressive strength is higher than 150KPa, and the heat value is less than 3MJ/kg.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a fire-proof adhesive and its application in improving the performance of flame-retardant polystyrene foam insulation boards. Background technique [0002] Building insulation materials play an important role in creating a suitable indoor thermal environment and saving energy in building insulation. In the current external wall insulation system, flame-retardant polystyrene (EPS) insulation boards are generally used. It has the characteristics of light bulk density, low thermal conductivity, long stable period, good permeability resistance, good heat insulation performance, convenient construction, and low engineering cost, so it is widely used. [0003] The patent application with document number CN102675762A discloses a halogen-free flame-retardant polystyrene foam material and a preparation method thereof, and CN102808461A discloses an EPS fireproof insula...
