Abstract

The invention discloses an inorganic fiber composite thermal insulation material and a preparation method thereof, which belong to the technical field of thermal insulation material preparation. The thermal insulation material is formed by dispersing and mixing polyphenyl granules, silica, white carbon black, glass wool and aluminum silicate wool through a strong airflow. The thermal insulation material disclosed by the invention has the advantages of light volume weight and small heat conductivity factor, can adapt to complex building nodes and is suitable for thermal insulation of outer walls of buildings.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation material preparation, and in particular relates to an inorganic fiber composite thermal insulation material and a preparation method thereof. Background technique [0002] At present, cement, aerated concrete, benzene board, glass wool board, phenolic foam insulation board, etc. are widely used in buildings as insulation materials for building interior or exterior walls. The disadvantages of cement and aerated concrete are relatively large bulk density and large thermal conductivity. The benzene board and the glass wool board are prone to cracks due to large drying shrinkage, and have poor adaptability to complex-shaped building joints. Phenolic foam insulation board is easy to release formaldehyde gas when heated. Therefore, there is an urgent need for a new type of thermal insulation material with small bulk density, low thermal conductivity, safety, green and environmental protecti...
