Material for manufacturing modified phenolic fireproof insulating plate

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 comprises the following components in part by weight: 100 parts of expandable phenolic resin, 6 to 8 parts of composite surfactant, 5 to 7 parts of foaming agent and 8 to 10 parts of curing agent. Due to the adoption of the technical scheme, the material has the advantages of large foam expansion rate, small apparent density, uniform cell distribution, high closed porosity, low hygroscopicity, large compressive strength, good foaming effect, most excellent comprehensive performance of foam, and capability of being applied to outer wall construction (an 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 modified phenolic fireproof insulation boards Background technique [0002] Due to the high energy consumption of buildings, serious energy waste is a very common problem. Therefore, building energy conservation is a direct and cheap systematic project to alleviate energy shortage. Currently used building insulation materials, such as extruded polystyrene boards and polystyrene boards, have potential safety hazards due to their shortcomings such as flammability, toxic smoke, and poor water absorption. Phenolic foam is the fastest-growing variety of foam insulation materials due to its easy-to-obtain raw materials, low price, excellent product performance, and excellent thermal insulation performance. , self-extinguishing, low smog, good waterproof and air permeability, etc., can be well applied in the implementation of exterior walls (exte...
