Problems solved by technology

However, the tensile strength of the rock wool insulation board is low in the direction perpendicular to the board surface. When used in the external wall insulation system, its wind resistance is poor and has certain safety hazards; in addition, the water absorption rate of the rock wool insulation board is too high , the thermal insulation performance will be reduced after absorbing water, and it will be easily damaged in a large area in a freeze-thaw environment, which will cause certain difficulties to the popularization and application of related technologies

Abstract

The invention discloses a three-dimensional reinforced hydrophobic rock wool insulation board which comprises a rock wool insulation board and is characterized in that high temperature resistance reinforcing fibers are arranged in the rock wool insulation board; the high temperature resistance reinforcing fibers are arranged in a three-dimensional mode; and a hydrophobic protection layer is also arranged on the outer surface of the rock wool insulation board. The tensile strengths of the rock wool insulation board disclosed by the invention in the directions of a horizontal board surface and a vertical board surface are greatly improved. Due to the hydrophobic protection layer, the waster absorption of the rock wool insulation board is reduced. The rock wool insulation board disclosed by the invention has the advantages of fire resistance, heat preservation, high tensile strength, low water absorption, excellent impact resistance and the like. The defects of performances of the existing rock wool insulation board are overcomes. Moreover, the three-dimensional reinforced hydrophobic rock wool insulation board accords with the national requirements on environment protection and energy saving and can be widely applied to the wall energy-saving insulation projects in the construction trades.

Description

technical field [0001] The invention relates to a three-dimensionally reinforced hydrophobic rock wool insulation board, in particular to a reinforced hydrophobic rock wool insulation board which is three-dimensionally reinforced by using glass fiber and other high temperature resistant fiber materials, and whose surface is waterproofed with a hydrophobic protective layer. plate. Background technique [0002] External wall insulation system is a very important part of energy-saving buildings. Conventional insulation boards mainly use organic combustible materials (such as polystyrene foam, polyurethane, etc.) as insulation materials. This kind of insulation board materials are easy to burn. Buildings of this material pose a certain fire hazard. A more reasonable approach is to use non-combustible thermal insulation materials as insulation boards in the external thermal insulation system of building exterior walls. At present, rock wool thermal insulation boards are mainly u...
