Metallic laminated plate with a fireproof level A2 and production method thereof

Abstract

The invention discloses a metallic laminated plate with a fireproof level A2. The metallic laminated plate comprises a core material, wherein a metal sheet is adhered to the surface of a core materialthrough a macromolecular membrane, an adhered face of the core material and the metal sheet is a corrugated surface, and the core material comprises the ingredients in parts by weight: 80-95 parts ofcalcium carbonate, 100-120 parts of magnesium hydroxide, 70-80 parts of silicon powder, 50-60 parts of high bauxite, 15-20 parts of graphene, 10-15 parts of pearlite, 50-60 parts of titanium oxide, 20-30 parts of barite powder, 5-15 parts of staple polypropylene fibers, 1-2 parts of glass fibers, 50-65 parts of silicon carbide, 60-80 parts of aluminum hydroxide, 10-20 parts of zinc molybdate and130-145 parts of acrylic emulsion. According to the metallic laminated plate with the fireproof level A2, disclosed by the invention, the metal sheet is adhered to the surface of the core material through the macromolecular membrane, and the adhered face of the core material and the metal sheet is the corrugated surface, so that the peeling strength of the core material and the metal sheet is improved.

Description

technical field [0001] The invention relates to a metal composite board, in particular to an A2 grade fireproof metal composite board and a production method thereof. Background technique [0002] With the frequent occurrence of domestic large-scale fire accidents in recent years, the country has put forward higher and higher requirements for the fire performance of materials used in high-rise buildings. The traditional aluminum-plastic panels can only reach Class B due to their fire protection rating. It is very easy to cause fire under conditions such as discharge and discharge, and it is increasingly exposing its own limitations. [0003] Fireproof aluminum composite board is a new type of non-combustible product, the surface is aluminum alloy, the middle core material is natural inorganic material, the board structure is bonded with special polymer film, heated and cured, through advanced technology to achieve perfect combination, improve the excellent quality of the boa...

AI Technical Summary

Problems solved by technology

However, aluminum composite panels often rely on surface coating paint to obtain color, and the fire resistance is poor, and the peeling strength between the core material and aluminum alloy is not high, resulting in short service life and poor oxidation and corrosion resistance.
