Building exterior wall sandwich thermal insulation and permeation prevention composite board

Abstract

The invention relates to the technical field of composite board manufacturing, in particular to a building exterior wall sandwich thermal insulation and permeation prevention composite board. The building exterior wall sandwich thermal insulation and permeation prevention composite board comprises a hollow color steel pipe, an inner polyurethane layer and an outer polyurethane layer are installedon the two sides of the hollow color steel pipe correspondingly, evenly-distributed fixing tenons are arranged on one side of the hollow color steel pipe, uniformly-distributed positioning mortises are formed in one side of the inner polyurethane layer, the hollow color steel pipe and the inner polyurethane layer are connected through the fixing tenons and the positioning mortises in a mortise andtenon joint mode, and one side of the inner polyurethane layer and one side of the outer polyurethane layer are each provided with a right bonding layer in a bonding mode. Through the mortise and tenon joint of a small plug and the outer polyurethane layer, when a composite board is on fire, carbon dioxide gas in the hollow color steel pipe expands and extrudes the small plug, so that the on-fireouter polyurethane layer is pushed to fall off and isolate open fire, and meanwhile, the carbon dioxide gas can be sprayed out of the hollow color steel pipe after the small plug is pushed to fall off, air around the composite board is extruded, so that spreading of open fire is hindered.

Description

technical field [0001] The invention relates to the technical field of composite board manufacturing, in particular to a sandwich insulation and anti-seepage composite board for building exterior walls. Background technique [0002] Because of the material problem of the wall, the phenomenon of air infiltration and condensed water will appear in the building wall without secondary processing, resulting in poor thermal insulation effect and serious water infiltration of the building. [0003] In order to solve these problems, the current method of adding composite panels to the exterior walls of buildings is often used to enhance their thermal insulation and waterproof penetration capabilities. However, the current sandwich materials for exterior wall composite panels generally include double-layer decorative panels. , double-layer waterproof board, double-layer fire-proof board, insulation layer, etc., resulting in cumbersome preparation and high cost, and at the same time, ...
