Fireproof and flame-retardant insulation phenolic foam board

Abstract

The invention belongs to the technical field of chemical heat preservation materials, and is a fireproof and flame-retardant phenolic heat preservation foam board, which consists of the following raw materials in parts by weight: 65-80 parts by weight of phenolic resin, 5-15 parts of foaming agent, 5-10 parts of curing agent, and benzenesulfonate Acid 2.5-5, benzoic acid 2.5-5, additives 1-5; during preparation, put phenolic resin, foaming agent, and additives into a reaction kettle and keep warm at room temperature, stir and mix evenly, and then add curing agent, benzenesulfon A closed-cell rigid foam board made under the action of acid and benzoic acid; the product of the present invention has the characteristics of light weight, non-combustibility, low smoke, high temperature resistance, non-toxic, and no dripping. Due to the high closed-cell rate of phenolic foam, the It has low thermal conductivity, good heat insulation performance, and has water resistance and water vapor permeability. It is an ideal thermal insulation and energy-saving material. The foam insulation material is light in weight and convenient in construction.

Description

technical field [0001] The invention belongs to the technical field of chemical heat preservation materials, in particular to a fireproof and flame retardant phenolic heat preservation foam board. Background technique [0002] In my country, fires caused by thermal insulation materials occur from time to time, causing casualties of personnel and property, and causing huge losses to people's lives. There are many deficiencies in various thermal insulation materials on the market. Polyurethane thermal insulation boards are flammable and prone to fire Poisonous gas, endangering human health; polystyrene insulation board is easy to burn when exposed to fire, will shrink after a long time, and has poor thermal insulation performance; the defects of rock wool and glass wool are harmful to the environment, breeding bacteria, high water absorption, poor heat insulation effect, poor strength, The service life is short, but the phenolic thermal insulation foam board is non-combustible, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the original foam insulation material, such as flammability, smoke, and thermal deformation, and to provide a fire-resistant and flame-retardant phenolic insulation foam board by retaining the characteristics of the original foam insulation material, such as light weight and convenient construction.
