Abstract

The invention relates to an architectural energy-saving material, particularly a phenolic foam which is prepared by foaming and curing a phenolic resin, a surfactant, a toughener, a stabilizer, a foaming agent and an acid catalyst. The material is characterized in that the stabilizer is floating beads which account for 1.5-10 wt% of the phenolic foam. The phenolic foam material has the advantages of high tensile strength and high dimensional stability, and solves the problem of high warping tendency of boards when being heated.

Description

technical field [0001] The invention relates to a building energy-saving material, in particular to a phenolic foam. Background technique [0002] Known as the "King of Thermal Insulation Materials", phenolic foam is a new generation of thermal insulation, fireproof and sound insulation materials. Phenolic foam material is a polymer organic rigid aluminum foil foam product, which is foamed by thermosetting phenolic resin. It has the characteristics of light weight, fireproof, non-combustible in case of open flame, smokeless, non-toxic, non-dripping, wide temperature range (-196~+200℃), non-shrinkage and non-brittle under low temperature environment. [0003] However, the traditional phenolic foam board has poor dimensional stability and strength, and the board surface is prone to warping when heated. To solve this problem, there are mainly two types of reinforcing materials currently used in the world: one is glass fiber or glass fiber braid, the addition of this materia...
