A waterproof exterior wall insulation decorative board

Abstract

The invention belongs to the technical field of building materials, in particular to a waterproof exterior wall thermal insulation decorative board. Including thermal insulation laminates, decorative laminates and spray-painted surface layers, there is also a structural anchor rib between the thermal insulation laminate and the decorative laminate, the structural anchor ribs are fixedly connected to the decorative laminate, and on the left side of the thermal insulation laminate Between the edge and the lower edge of the left side of the decorative laminate, a left vertical seam lap joint leak-proof water guide line is set. The upper outer edge of the laminate is overlapped with the inner line surface of the throwing hole by the transverse seam, and the transverse seam of the lower inner edge of the decorative laminate overlaps the outer line surface of the throwing hole with the transverse seam of the upper outer edge of the adjacent lower decorative laminate. The technical scheme of connecting the inner line and the surface of the throwing port, the exterior wall thermal insulation decorative panel of the present invention conforms to the factory production advocated by the state at present, and the purpose of simplifying the construction, and the cost is low, meets the needs of the current construction industry, and has broad market prospects .

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a waterproof exterior wall thermal insulation decorative board. Background technique [0002] With the rapid development of my country's economy, higher and higher requirements for energy saving and emission reduction have been put forward, and the country has put forward mandatory insulation standards for the external wall insulation of buildings, advocating factory production and simplifying construction. In order to realize the thermal insulation of external walls, most construction units adopt the method of bonding thermal insulation boards with polymer bonded mortar for thermal insulation construction. Specifically, first use polymer bonding mortar to paste insulation boards (extruded polystyrene boards, foamed polyurethane boards, etc.) Cement bonded mortar calendered surface brush exterior wall paint, or paste exterior wall tiles, etc.). The disadvantages of t...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: first, the construction is difficult and requires a large amount of labor; second, the bonding is not firm, and there are quality and safety hazards such as cracking and falling off; third, there is a hidden danger of water leakage, which is one of the common problems in the current construction industry. It is called a common problem; the fourth is that the large surface is uneven, which affects the appearance

In addition, the above-mentioned extruded polystyrene boards and foamed polyurethane boards are less and less used in the construction industry because they are not fireproof, and from the perspective of fire prevention, rock wool, glass wool, and phenolic foam boards have become more and more popular. Applied to the insulation of external walls, but it is very inconvenient to use the above-mentioned fireproof materials, or the materials are too brittle and easy to damage, or the shape is irregular, so it is not easy to fix. It is even more difficult to get up, these are the thorny problems currently encountered

Although there are also composite thermal insulation decorative panels for construction, the design of the structure is not reasonable enough. The problem of rainwater entering, there is no effective drainage channel, which affects the quality of the external wall

[0003] The applicant's patent application with application number 2014104576914 describes a waterproof exterior wall thermal insulation decorative panel. The thermal insulation decorative panel adopts a two-layer structure, followed by a thermal insulation laminate and a structural decorative laminate. The structural decorative layer The panel includes corner lines, and the corner lines are connected with each other to form a closed frame, and the decorative panel is fixed in the closed frame, that is, the thermal insulation decorative panel is provided with vertical seams on four sides to overlap the leak-proof and water-conducting lines, the structure is complex and the cost is high , the scope of application is limited to a certain extent, and the applicant has provided a new waterproof exterior wall thermal insulation decorative panel through research and innovation
