Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite lightweight, high-strength, flame-retardant and weather-resistant foam insulation material. Background technique [0002] Building insulation materials can reduce the loss of 20-30% of the heat or cold air in the house to the outdoor environment through the walls, thereby avoiding a lot of energy waste and effectively saving resources. At present, with the urgent need of energy saving and building energy saving, higher requirements are put forward for building insulation materials. The existing building insulation system is mainly based on polystyrene particle insulation mortar, polyethylene board, extruded board and polyurethane, etc., and has the following disadvantages: the insulation effect of polystyrene particle insulation mortar is poor; the flame resistance of polyethylene board and extruded board is poor , easy to produce molten droplets in case of fire, re...
