Heat-insulation material for building external wall and construction method

Abstract

A thermal insulation material for building exterior walls and a construction method thereof, is characterized in that it is a composite board, which includes a closed-cell foamed plastic board and a metal panel compounded on the surface of the closed-cell foamed plastic board; its production The construction method includes the following steps: first, the foamed plastic board with closed cells is combined with the metal panel to form a non-folded metal-faced foamed plastic composite board using the existing technology; the foamed plastic board in the non-folded composite board A right-angled side groove is processed on the periphery of the side of the plate close to the metal panel, and then the four corners of the metal panel are cut into square openings, and the edge part of the metal panel is bent toward the direction of the side groove, so that it is composited on the foam plastic The metal panel on the board is in the shape of a gusset. Then use special bonding mortar to bond on the outer wall surface and use glass glue to treat the groove-shaped joints between the boards. The invention has the advantages of simple construction process, low cost, good thermal insulation and waterproof effect of the wall, and good decorative effect.

Description

Technical field: [0001] The invention relates to a thermal insulation material used for building exterior walls and a construction method thereof, belonging to the field of building thermal insulation materials and construction methods. Background technique: [0002] In the existing external wall insulation systems, the insulation mortar has disadvantages such as low strength, poor insulation performance, and long construction period due to wet operation compared with foam plastics. At present, the "expanded polystyrene board thin plaster external wall external insulation system" widely used in the northern region, referred to as the thin plaster system, has disadvantages such as poor durability, easy cracking, and easy hollowing. The above two types of thermal insulation systems also have the disadvantage of low flatness due to the need for manual plastering, so they are not suitable for high-grade exterior walls. [0003] In the prior art, extruded polystyrene boards are ...

Problems solved by technology

Other types of external wall insulation systems, such as the double-layer wall insulation system with glass wool in the middle, and the system with foamed polyurethane filling in the gap between the double-layer walls, are all expensive and not easy to promote and use.
