Abstract

The invention provides a preparation method of a high energy-saving type modified environment-friendly phenolic fireproof insulation board. The method comprises the following steps of: mixing and evenly stirring leftover and waste materials of the phenolic resin fireproof insulation board, waste rubber powder, expandable phenolic resin, modifying agents, a surface active agent and a foaming agent; then, adding a composite curing agent into the mixture, stirring the mixture and the agent, and pouring the obtained mixture into a mould to obtain the phenolic resin fireproof insulation board. By adopting the double modifying agents, the method can alleviate environment pollution caused by the waste rubber and the leftover and waste materials of the phenolic resin fireproof insulation board, reduce energy consumed by the preparation of the phenolic resin fireproof insulation board, improve the strength and the toughness of the phenolic insulation board, reduce the brittleness of the phenolic insulation board and lower the industrial cost, is beneficial to improving economic benefits, and meets the construction demand of a building outer wall (specifically an outer wall insulation system).

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a high-energy-saving modified environment-friendly phenolic fireproof insulation board. Background technique [0002] 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 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. But a shortcoming of prior art phenolic foam is brittle, tensile strength is not high, simultaneously phenolic foam is a kind of in macromolecule material, to the consumption of energy, the pollution of environment is also very serious, e...
