Abstract

The invention provides a preparation method of an energy-saving and environment-friendly modified phenolic resin fireproof insulation board. The method is characterized by mixing leftover and waste materials of a phenolic resin fireproof insulation board, expandable phenolic resin, a modifier, a surfactant and a foaming agent, adding a curing agent after stirring the materials uniformly and pouring the mixture into a mold after stirring, thus obtaining the phenolic resin fireproof insulation board. By adopting the single solution, the environmental pollutions caused by the leftover and waste materials of the phenolic resin fireproof insulation board and energy consumption for producing the phenolic resin fireproof insulation board are reduced, the problem of warehousing lots of leftover and waste materials in actual production is also solved, the industrial cost is reduced, the economic benefits are improved, the strength and toughness of the phenolic resin fireproof insulation board are simultaneously improved, the fragility is reduced and the requirements of construction of exterior walls of buildings (exterior wall insulation systems) are met.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a method for preparing an energy-saving and environment-friendly modified phenolic resin fireproof and heat preservation board. Background technique [0002] Phenolic foam can be better used in external wall insulation systems due to its easy-to-obtain raw materials, low price, excellent product performance, flame retardant, self-extinguishing, low smoke, and good waterproof and air permeability. industry's attention. The production of phenolic foam insulation board is becoming more and more large-scale and industrialized. Correspondingly, a large amount of corners and waste materials have also appeared in the production and use process. Nowadays, about 500,000 liters of phenolic resin fireproof insulation boards are put into the construction market every year, and it is still increasing year by year. The recommended service life of phenolic resin firepro...
