Abstract

The invention provides a modified phenolic resin thermal insulation material. Raw materials of the thermal insulation material comprise raw materials for preparing phenolic resin, and modified seashell powder, and the raw materials of the thermal insulation material are uniformly mixed, polymerized and molded to prepare the resin. Impact experiments show that the addition of the modified seashellpowder improves the strength of the phenolic resin thermal insulation material, and meets requirements of environmentally friendly buildings.

Description

technical field [0001] The invention belongs to the technical field of environmental protection building materials, and in particular relates to a high-quality thermal insulation material. Background technique [0002] In recent years, due to the emphasis on building energy saving and external wall insulation, more and more new building insulation materials have been developed and applied to new buildings. Phenolic resin insulation material is an organic polymer hard aluminum foil resin product, which is a phenolic resin material foamed from thermosetting phenolic resin, due to its high closed cell rate, good thermal insulation performance and low thermal conductivity. , and has excellent characteristics such as water vapor permeability and water resistance, and has the characteristics of light weight, high fire resistance, non-combustibility in case of open flames, no dripping, non-toxic and smoke-free. No embrittlement and no shrinkage are the first choice for ideal insul...
