Galvanized composite board

Abstract

The invention discloses a galvanized composite board, and relates to the technical field of composite boards. The galvanized composite board is prepared by the following process flows: A, firstly, washing with water and then drying to 100 DEG C; B, bonding an aluminum board and a galvanized board through a high-temperature polymer bonding material; C, high-temperature extrusion: firstly, using an electromagnetic heating tube for rolling to 270 DEG C, and then heating and extruding five times, wherein the heating and extruding temperatures five times are respectively 170 DEG C, 190 DEG C, 210 DEG C, 230 DEG C and 270 DEG C; D, cooling: using processed purified water for cooling to 40 DEG C, and then using a fan for cold-blowing to 20 DEG C; E, finally, flattening. The galvanized composite board provided by the invention is reasonable in structure design, simple in process, durable, low in cost, high in strength, free from baking finish, environment-friendly, and convenient and reliable in mounting and welding.

Description

Technical field [0001] The invention relates to the technical field of composite panels, in particular to a galvanized composite panel. Background technique [0002] At present, the decorative panels used in indoor and outdoor decoration technology are either all-aluminum or ordinary steel plates. All-aluminum plates are relatively high in cost and low in strength. They are all painted on site, which pollutes the environment and is inconvenient for welding and installation. ; And ordinary steel plate is easy to fade, the grade looks relatively low, the use effect is not good, so the present invention designs a galvanized composite plate. Summary of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a galvanized composite board with low cost, high strength, not easy to fade, no environmental pollution, convenient and reliable installation and welding, and high-grade. [0004] In order to achieve the above objective...
