Grade-A fireproof metal decoration heat insulation plate and production process thereof

Abstract

The invention discloses a grade-A fireproof metal decoration heat insulation plate and a production process thereof. Improvement is performed based on a traditional adhesion material while two fireproof heat insulation materials are adopted, so that the manufactured metal decoration heat insulation plate can achieve grade-A fire prevention in a real sense, and the metal decoration heat insulation plate has the advantages of being stable in structure, high in strength, light in mass, low in cost and high in production efficiency. The invention further provides the grade-A fireproof metal decoration heat insulation plate. The heat insulation of the grade-A fireproof metal decoration heat insulation plate is performed through foaming glass or foaming ceramics, a second adhesion object between a heat insulation layer and a metal layer is used for adhesion through metal plate putty, so that the grade-A fire prevention in a real sense is achieved; and mortar layers are positioned on the two sides of the heat insulation layer, so that the structural stability is guaranteed.

Description

technical field [0001] The invention relates to a thermal insulation board used in the case of building decoration. More specifically, the present invention relates to a class A fireproof metal decorative insulation board used in building decoration and its production process. Background technique [0002] The existing metal decorative insulation boards are mainly classified according to the insulation materials; polyurethane insulation boards, rock wool insulation boards, etc., only rock wool insulation boards can achieve a fire rating of A. Rock wool and other flexible and loose materials are used as the insulation layer. After completion, the panel is easily deformed, which affects the construction quality; and to achieve the same insulation effect under the same conditions, the rock wool board is heavy and the price is high and uneconomical. [0003] Foamed ceramics and foamed glass are used as insulation materials, and their fire rating can also reach Class A. However,...

AI Technical Summary

Problems solved by technology

Rock wool and other flexible and loose materials are used as the insulation layer. After completion, the panel is easily deformed, which affects the construction quality; and to achieve the same insulation effect under the same conditions, the weight of the rock wool board is heavy and the price is high and uneconomical.

[0003] Foamed ceramics and foamed glass are used as insulation materials, and their fire rating can also reach Class A. However, due to the limitation of production technology for foamed glass and foamed glass insulation materials, they can only produce plates with a maximum size of 600*600. The maximum size of the thermal insulation decorative board is 1200*1650, which cannot meet the production of the largest size of the thermal insulation decorative board, and the utilization rate of the board is low when it is used as a thermal insulation decorative board of other specifications; and these two kinds of thermal insulation materials are used for practical In the process of making large-scale thermal insulation and decorative panels, the thermal insulation materials cannot be bonded into thermal insulation panels that meet the specifications. The reason is that the surface of the thermal insulation panel is not smooth after splicing foamed ceramics and foamed glass, which affects its combination with the metal decorative panel in the later stage. The stability of the metal decorative panel and the flatness of the surface of the metal decorative panel, and the insufficient flatness of the surface of the metal decorative panel will cause the deformation of the metal panel and affect the stability of its structure; the second is that after the splicing of foamed ceramics and foamed glass, there is splicing joints, resulting in a decrease in the strength of the plate, the stability cannot meet the requirements, it cannot meet the strength requirements of engineering installation, and it cannot be applied and promoted in the market

[0004] In addition, the traditional metal decoration layer and the insulation layer are bonded by polyurethane glue. The disadvantage is that polyurethane glue does not belong to the structural adhesive, which conflicts with the specifications of insulation materials; at the same time, its adhesion The strength is low, and the polyurethane fire protection grade is B2, so the traditional metal composite board cannot really meet the fire protection grade A standard; in addition, the curing and setting time of polyurethane is 8-12 hours, which leads to a long production cycle of the thermal insulation decorative board, Seriously affect production efficiency
