Composite rock wool reinforcement plate and preparation method for composite rock wool reinforcement plate

Abstract

The invention discloses a composite rock wool reinforcement plate and a preparation method for the composite rock wool reinforcement plate. The composite rock wool reinforcement plate comprises a core plate; wherein the core plate is composed of at least two rock wool slivers which are arranged side by side; the arrangement direction of fiber yarns of the rock wool slivers is in parallel with the thickness direction of the composite rock wool reinforcement plate; the four surfaces of the core plate in the length direction are wrapped by a layer of reinforced fiber layer; and the outer surface of the reinforced fiber layer is coated by a layer of mortar protecting layer. According to the composite rock wool reinforcement plate and the preparation method, the shortcomings of low tensile strength and low compression strength of common rock wool plate are overcome, the weak link of stress is eliminated, and the safety of the system is improved; and the composite rock wool reinforcement plate has the advantages of good heat insulating effect, high intensity, good fire-proof and humidity resistant performances, simple construction and long service life, so that the composite rock wool reinforcement plate can be widely applied to the fields of outer wall constructions of buildings.

Description

technical field [0001] The invention relates to a rock wool insulation board and a preparation method thereof. Background technique [0002] At present, fire accidents of external thermal insulation of external walls occur frequently, and the fire safety of external thermal insulation of external walls has become the focus of attention in the industry. Document No. 46 and Document No. 65 issued by the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development put the thermal insulation and fire protection function of external walls on the agenda, and clearly stipulated that Class A non-combustible thermal insulation materials should be used for external wall thermal insulation. The existing A-level thermal insulation products generally include foamed cement (concrete) thermal insulation boards, inorganic thermal insulation mortar and boards, and ordinary rock (mineral) wool boards. [0003] Foamed cement insulation board is a physical deformation of...
