Inorganic fiber composite insulation board

technical field

The utility model relates to the technical field of thermal insulation materials, in particular to an inorganic fiber composite thermal insulation board.

Background technique

Inorganic fiber insulation boards (including glass wool, mineral wool and rock wool insulation boards), as Class A non-combustible materials, are widely used in the field of insulation. However, when it is applied to the external thermal insulation system of building exterior walls, it has the disadvantages of high water absorption and low tensile strength, which seriously hinders its application in the field of building energy conservation. In the thermal insulation system of building exterior walls, the tensile strength between layers is usually required to reach 0.1 MPa, but the glass wool board, mineral wool board or rock wool board produced in large quantities in my country is difficult to achieve in terms of mechanical properties; and for The current solution to the problem of high water absorption is to use organic polymer waterproof materials for treatment, and this treatment method can reduce the fire resistance of glass wool, mineral wool or rock wool.

In view of the above-mentioned problems existing in the existing inorganic fiber insulation board, the designer of the utility model actively researched and innovated, and finally created a new type of inorganic fiber composite insulation board, which has the characteristics of high tensile strength and low water absorption.
