Fireproof thermal-insulation material, and preparation method thereof

Abstract

The invention discloses a fireproof thermal-insulation material. The fireproof thermal-insulation material comprises following raw materials, by weight, 20 to 30 parts of glass bead, 25 to 35 parts ofmodified meerschaum, 15 to 30 parts of attapulgite, 7 to 14 parts of ore fiber, 6 to 13 parts of glass fiber, 9 to 18 parts of phenolic resin, 6 to 11 parts of aerosil gel, 4 to 8 parts of zinc oxide, 3 to 5 parts of carboxymethylcellulose sodium, 1 to 2 parts of polyvinyl alcohol, 2 to 5 parts of honey, 3 to 4 parts of a foaming agent, 2 to 5 parts of a fire retardant, and 2 to 3 parts of a water repellent. According to a preparation method, the obtained product is provided with low heat conduction coefficient and density, high compressive strength and fracture strength, and excellent comprehensive performance through controlling the raw materials and raw material ratio.

Description

technical field

[0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a fireproof thermal insulation material and a preparation method thereof. Background technique

[0002] Building energy conservation, initially in developed countries, is to reduce the loss of energy in buildings, and it is generally called "improving the energy utilization rate in buildings". Under the condition of ensuring the comfort of buildings, energy is used rationally and energy utilization efficiency is continuously improved.

[0003] Building energy conservation specifically refers to the implementation of energy-saving standards during the planning, design, new construction (reconstruction, expansion), renovation and use of buildings, and the adoption of energy-saving technologies, processes, equipment, materials and products to improve thermal insulation performance and heating. Improve the efficiency of heating, air-conditioning, refr...
