Abstract

The invention relates to the technical field of building materials, in particular to a material for manufacturing a modified phenolic fireproof insulating plate. The material for manufacturing the modified phenolic fireproof insulating plate comprises the following components in part by weight: 100 parts of expandable phenolic resin, 2 to 20 parts of polyurethane prepolymer, 2 to 4 parts of surfactant, 5 to 7 parts of foaming agent and 8 to 10 parts of curing agent. The material improves the closed porosity of the phenolic fireproof insulating plate, reduces the hygroscopicity, quickens the speed of curing and molding reaction, also improves the intensity and roughness of the phenolic fireproof insulating plate, reduces the crispness of phenolic foam, and meets the requirements on outer wall construction (an outer wall insulation system) of buildings.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a material for manufacturing a modified phenolic fireproof and thermal insulation board. Background technique [0002] Due to the high energy consumption of buildings and serious energy waste is a very common problem, building energy conservation is a direct and cheap systematic project to alleviate the energy shortage. The currently used building insulation materials, such as extruded plastic boards and polystyrene boards, have potential safety hazards due to their shortcomings such as flammability, high toxic smoke, and poor water absorption. Phenolic foam has the characteristics of easy availability of raw materials, low price, excellent product performance, flame retardancy, self-extinguishing, low smoke, good waterproof and air permeability, etc., and can be well used in external wall insulation systems, so it is increasingly attracting people's attention. .
