Problems solved by technology

This further leads to the loss of thermal insulation effect; in addition, since the surface of expanded perlite particles is open, a large amount of stirring water can be absorbed during use, which will cause the material to lose a certain strength after drying
2. Because it is used in combination with organic materials, it changes from non-combustible to flammable, and it will quickly ash, disintegrate, and break when used at high temperatures (above 200 ° C), which seriously affects the service life, generally 2 to 3 need to replace every year
3. Generally pollute the environment and harm human health
However, due to the destruction of the structure of the expanded perlite granular material in the preparation and molding process due to stirring, it will inevitably lose a part of its thermal insulation performance. Therefore, a new composite material is needed. The disclosed high-efficiency energy-saving thermal insulation material can overcome the structural damage of the material, thereby having better thermal insulation performance

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a thermal insulation composite material composition, and also to a method for preparing the thermal insulation composite material composition. Background technique [0002] Thermal insulation materials are widely used in lining materials, enclosure materials and insulation materials in thermal insulation projects in the industrial and living fields, such as equipment and pipelines that require thermal insulation in petroleum, chemical, thermal power heating network, metallurgical and other systems. It can also be used for heat insulation and fireproof layers of building walls, fireproof partition layers, light-weight mobile room wall panels, and constant temperature rooms. There are many kinds of thermal insulation materials, but they can be generally divided into inorganic and organic types according to their composition, and can be divided into traditional type and modern type a...
