Problems solved by technology

However, the strength of rock wool strips is low, and the water absorption is large, so it is difficult to make a fireproof insulation board integrated with heat preservation and decoration.
In addition, the cost of rock wool strips is relatively high, and qualified products mainly rely on imports, causing certain difficulties to the promotion and application of related technologies

Abstract

The invention relates to a hard inorganic non-ignitable adiabatic fiber expansion bead thermal insulation board. The combustion performance level of the fiber expansion bead thermal insulation board is level A. The fiber expansion bead thermal insulation board is low in water absorption, high in compression strength and tensile strength, long-term and stable in thermal conductivity, good in dimensional stability and freezing resistance, resistant to high temperature and low temperature, anti-aging, long in service life and capable of being applied to thermal insulation of various building outer walls, floors and roofs.

Description

technical field [0001] The invention relates to a thermal insulation board material, in particular to a fiber expanded bead thermal insulation board and a production method thereof. Background technique [0002] External wall insulation system is a very important part of energy-saving buildings and is widely used in construction projects at home and abroad. Among them, the thermal insulation and decoration integrated system composed of thermal insulation and decorative boards is convenient for construction and has good decorative effects, and is currently very popular. Conventional thermal insulation decorative panels mainly use organic combustible materials (such as polystyrene foam, polyurethane, etc.) It has brought serious difficulties to fire fighting and rescue work, resulting in casualties and property losses. At the same time, this type of insulation material also has disadvantages such as easy aging, poor dimensional stability, and low bonding strength with surfac...
