Reticular dimensional reinforced composite heat preservation rock wool board

Abstract

The invention discloses a reticular dimensional reinforced composite heat preservation rock wool board; the reticular dimensional reinforced composite heat preservation rock wool board is formed by combining a reticular dimensional reinforced rock wool heat preservation board with an organic heat preservation board in an adhering manner; the reticular dimensional reinforced rock wool heat preservation board comprises a rock wool layer, an upper reticular structure layer, a lower reticular structure layer and connecting pieces, wherein the upper and lower reticular structure layers are respectively arranged on the upper and lower surfaces of the rock wool layer, and the connecting pieces penetrate through the rock wool layer to connect the upper reticular structure layer with the lower reticular structure layer. The reticular dimensional reinforced composite heat preservation rock wool board provided by the invention can be applicable to regions with higher requirements on heat preservation and heat insulation; compared with the organic heat preservation board, the tensile strength and wind pressure resistant strength of a heat preservation system can be greatly improved; compared with a traditional rock wool heat preservation board, the thickness of the heat preservation system is effectively reduced, and the safety of the system structure is improved; meanwhile, the reticular dimensional reinforced rock wool heat preservation board on the surface can play the role of a fireproof barrier, so as to form an effective fireproof shield, so that the fireproof performance of the organic heat preservation board is greatly improved, and the fireproofing problem can be solved more radically by adopting the dual-composite mode.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building construction, and in particular relates to a composite thermal insulation rock wool board reinforced with mesh. Background technique [0002] With the needs of energy conservation, environmental protection and the establishment of a conservation-oriented society, my country has been vigorously advocating and promoting building energy conservation. Therefore, various building wall insulation technologies and materials continue to emerge. [0003] According to the fire protection level of buildings, my country divides external wall insulation materials into four levels, namely A level, B1 level, B2 level and B3 level. Specifically, Class A is an inorganic material with no ignition point and thermal insulation effect, called non-combustible material. Class B1 is a flame retardant insulation material. Although it can be ignited, it can be extinguished automatically ...

AI Technical Summary

Problems solved by technology

The composite board has high shear strength and tensile strength. However, the insulation core material composed of rock wool and two or more polyurethane ribs foamed in rock wool at intervals is still used as a filler, and does not give the entire system Provide strength; at the same time, because it is difficult for rock wool to be combined with the steel plate, connecting ends are provided at both ends of the composite plate. There are also the problems of complicated process and high production cost, which are not conducive to market popularization and promotion.
