Composite material fireproof insulation board and preparation method thereof

Abstract

The invention discloses a fireproof heat insulation board adopting a composite material and a preparation method of the fireproof heat insulation board. The board is prepared from raw materials in parts by weight as follows: 70-80 parts of expanded perlite, 25-30 parts of thermoplastic phenolic resin, 15-19 parts of a curing agent, 8-14 parts of electrospun CNT (carbon nanotube) composite micro-nanofibers, 8-14 parts of carbonized electrospinning CNT composite micro-nanofibers, 6-12 parts of aluminum hydroxide and 4-7 parts of medical stone powder, wherein the electrospun CNT composite micro-nanofibers are organic polymer material / CNT composite micro-nanofibers prepared with an electrospinning method, and the carbonized electrospun CNT composite micro-nanofibers are carbonized fibers prepared from electrospun CNT composite micro-nanofibers through peroxidation, carbonization and activation. The board can meet the level-A non-combustible fire control requirement, is small in heat conductivity coefficient and good in thermal insulation property and can meet the requirement of building energy conservation.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a composite material fireproof thermal insulation board for building thermal insulation and a preparation method thereof. Background technique [0002] Building insulation materials play an important role in creating a suitable indoor thermal environment and saving energy in building insulation. This type of material takes measures to reduce the indoor heat of the building to the outside by taking measures to maintain the building's indoor temperature. . There are two main types of thermal insulation materials used in buildings in my country: inorganic thermal insulation materials and organic thermal insulation materials. Inorganic thermal insulation materials have a large thermal conductivity and poor thermal insulation effect. According to the energy-saving rate stipulated by the relevant national regulations in charge of the industry, the thickness of the thermal i...

AI Technical Summary

Problems solved by technology

Inorganic thermal insulation materials have a large thermal conductivity and poor thermal insulation effect. According to the energy-saving rate stipulated by the relevant national regulations in charge of the industry, the thickness of the thermal insulation material must be increased, and because of its large bulk density, it not only increases the building load, but also gives Construction brings a lot of inconvenience; in comparison, organic thermal insulation materials have a small thermal conductivity, better thermal insulation effect, and have the characteristics of light weight, high strength and convenient construction, but organic thermal insulation materials have two fatal shortcomings that cannot be overcome , one is flammable, the other is not resistant to high temperature, it is easy to carbonize at high temperature and lose its thermal insulation performance

In March 2011, the Ministry of Public Security has clearly stipulated that the application of B-grade thermal insulation boards in building exterior walls is required, and my country's building exterior wall insulation is required to use A-grade non-combustible materials. Organic thermal insulation materials cannot meet A-grade standards, which limits their use Applications in the field of building insulation

Although inorganic thermal insulation materials can meet the fire-fighting requirements of Class A, the thermal insulation performance of existing inorganic thermal insulation materials is poor, and it is difficult to meet the requirements of building energy conservation.
