A2 grade fireproof copper composite board and production method thereof

Abstract

The invention discloses an A2-level fireproof copper composite plate. The A2-level fireproof copper composite plate comprises a core material, wherein the surface of the core material is adhered witha copper plate through a macromolecular film; the adhesion surface of the core material and the copper plate is a corrugated surface; the core material is prepared from the following component in parts by weight: 80 to 95 parts of calcium carbonate, 100 to 120 parts of magnesium hydroxide, 70 to 80 parts of silica powder, 50 to 60 parts of high alumina bauxite, 15 to 20 parts of graphene, 10 to 15parts of perlite, 50 to 60 parts of titanium oxide, 20 to 30 parts of barite powder, 5 to 15 parts of polypropylene staple fiber, 1 to 2 parts of glass fibers, 50 to 65 parts of silicon carbide, 60 to 80 parts of aluminum hydroxide, 10 to 20 parts of molybdenum zinc oxide, 130 to 145 parts of acrylic latex and 10 to 15 parts of high-temperature resistant powder. According to the A2-level fireproof copper composite plate disclosed by the invention, the surface of the core material is adhered with the copper plate through the macromolecular film, and the adhesion surface of the core material and the copper plate is the corrugated surface, so that the stripping strength of the core material and the copper plate is improved.

Description

technical field [0001] The invention relates to a copper composite board, in particular to an A2 grade fireproof copper 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 b...

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.
