Abstract

The invention discloses a preparation method of a novel heat isolating nanometer material. A Cu-BTC-SiO2 nanometer material, polyethylene resin, polycarbonate, barium stearate, glass fiber, ethyl methacrylate and ethylene oxide are main raw materials; through evenly mixing Cu-BTC-SiO2 nanometer material, polyethylene resin, barium stearate, silicon dioxide and glass fiber, ethyl methacrylate and ethylene oxide are added at a certain temperature to react and perform primary crosslinking; then aluminum oxide is added for further reaction, thus the polymer is capable of penetrating the material at the high temperature, and the crosslinking degree of the material is improved. The nanometer material is wide in source and low in production cost; the nanometer heat isolating material is high in intensity, small in volume density, low in heat conductivity coefficient, and excellent in heat isolating effect.

Description

technical field [0001] The invention relates to a preparation method of a novel heat-insulating nanocomposite material, which belongs to the technical field of heat-resistant materials. Background technique [0002] Insulation materials refer to materials or material composites that have thermal insulation properties and can shield heat flow. They usually have the characteristics of light weight, looseness, porosity, and low thermal conductivity. They are widely used in industry to prevent heat from thermal equipment and pipelines. Lost, or used in freezing and low temperature, so thermal insulation materials are also called thermal insulation or cold insulation materials. At present, there are many kinds of heat insulation materials commonly used, but generally with the increase of temperature, the heat insulation performance of heat insulation materials decreases, especially the high temperature resistance of many heat insulation materials themselves is poor, which greatly...
