A kind of inorganic fiber insulation board and its preparation method and application

Abstract

The invention relates to the technical field of thermal insulation materials, and specifically discloses an inorganic fiber thermal insulation board as well as its preparation method and application. The inorganic fiber insulation board includes the following components: 15-30 parts of metallurgical slag, 20-50 parts of coal gangue, 10-30 parts of elutriated Longyan soil, 30-60 parts of alumina, 30-50 parts of silicon oxide, and talcum powder 5‑10 parts and Fluorite 3‑5 parts. The inorganic fiber insulation board provided by the present invention makes full use of solid waste and realizes the resource utilization of solid waste. At an average temperature of 500°C, the thermal conductivity is 0.03-0.04w / (m.k) (average temperature 500°C), hydrophobic The rate is 99.3% to 99.5%, and the volume water absorption rate is 1.2% to 1.8%. It can be widely used in the insulation of marine cabins, and can achieve good thermal insulation, heat insulation, and moisture-proof effects. The raw materials are cheap and easy to obtain, and have a wide range of applications. Application prospect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an inorganic fiber thermal insulation board and its preparation method and application. Background technique [0002] Due to its high humidity and high salinity environment, marine thermal insulation materials have higher requirements on the moisture-proof and anti-halogen performance of thermal insulation materials than general building thermal insulation materials. At present, the main insulation materials for marine cabins on the market are mainly rock wool materials, and because the traditional operating environment generally has a large temperature difference, it is prone to problems such as moisture return, strong water absorption, and rapid strength decay during long-term use. There are problems such as high preparation cost, non-continuous production and high energy consumption. Therefore, how to solve the performance deficiencies of the existing mar...

Problems solved by technology

At present, the main insulation materials for marine cabins on the market are mainly rock wool materials, and because the traditional operating environment generally has a large temperature difference, it is prone to problems such as moisture return, strong water absorption, and rapid strength decay during long-term use. There are problems such as high preparation cost, non-continuous production, and high energy consumption

Therefore, how to solve the performance deficiencies of the existing marine thermal insulation materials and the problems of high production cost and non-continuous production have become the key issues that R&D personnel need to solve urgently.
