Abstract

The invention provides a high-fire-resistant rigid polyurethane foam external wall insulation material and a preparation method thereof. The high-fire-resistant rigid polyurethane foam external wall insulation material comprises a component A and a component B. The component A comprises, by weight, 1-4 parts of chlorinated polypropylene resin, 4-16 parts of brominated epoxy resin, 60-80 parts of polyether polyol, 5-10 parts of glass beads, 1-4 parts of catalysts, 15-30 parts of fire retardants, 1-3 parts of stabilizers and 15-30 parts of foaming agents. The component B comprises polyphenyl polymethylene polyisocyanate. The foaming agents comprise 1-5 parts of pentane, 6-12 parts of amyl pentafluoride and 2-6 parts of dichloroethane. The fire resistance of the insulation material is improved while excellent mechanical property is kept.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for external walls, and in particular relates to a high flame-retardant polyurethane rigid foam thermal insulation material for external walls and a preparation method thereof. Background technique [0002] The organic insulation materials currently used on a large scale in my country's building energy conservation mainly include EPS (polystyrene foam), PS (extruded polystyrene foam) and PU (polyurethane foam), all of which are flammable organic insulation materials. The biggest advantage is the quality Lightweight, good heat preservation and heat insulation; the biggest defect is poor fire safety, easy aging, and easy burning. If these new building energy-saving materials have not been modified by the chemical structure of flame retardant and smoke reduction, if they are simply added with flame retardants, there will be serious fire hazards, leading to frequent building fire a...
