The processing method of the copper-aluminum composite profile is as follows: with the surface being degreased and dried, the aluminum alloy substrate is bonded on a rolling machine; the polyurethane reactive hot melt adhesive is evenly sprayed on the external surface of the aluminum alloy substrate; the width of the spraying adhesive is more than 5mm and the thickness of the spraying adhesive is between 0.1mm and 0.5mm; the operation speed on the rolling machine is 5 to 6m/min and the heating power is 8KW, and the copper plate is pressed and bonded on the aluminum alloy substrate. The copper-aluminum composite profile and the processing technology of the invention improve the wear resistance and the acid and alkaline resistance of the copper-aluminum composite profile and increase the bonding intensity of the copper plate and the aluminum alloy substrate. Copper doors and windows decorated by the invention not only have various clear art lines, but also can reach the corresponding processing accuracy.
Description
The technical field is as follows: the invention relates to the field of sectional materials, in particular to a copper-aluminum composite sectional material and a processing technology thereof.
Background art: copper decoration is one of various buildings which is commonly known by people, traditional copper doors and windows and other decorations adopt square steel, angle steel and the like with lining inside, an internal keel is manufactured by welding, a copper plate strip with the thickness of 1.0mm is adopted outside, the copper plate strip is formed by shearing and folding and is glued on the internal keel, and irregular arcs, concave and convex lines of corners and machining precision can not be solved in the shearing and folding process. Meanwhile, in the processing and manufacturing process, the process is correspondingly complex, the efficiency of finished products is low, and the cost is high. In addition, the current market also has an aluminum profile copper plating process, and the process has the following problems: the copper-plated film is easy to fall off, has low wear resistance, cannot meet the requirements of quality assurance in acid and alkali resistance, ageing resistance and the like, and can not meet the requirements of environmental protection due to environmental pollution.
The invention content is as follows: in order to solve the problems, the invention provides the copper-aluminum composite section which is firm in bonding, high in wear resistance and environment-friendly.
The invention also aims to provide a processing technology of the copper-aluminum composite section.
In order to achieve the purpose, the invention adopts the technical scheme that: a copper-aluminum composite section comprises an aluminum alloy base material, and a copper plate is bonded with the aluminum alloy base material through a glue layer. Wherein,
the thickness of the copper plate is 0.05 mm-0.15 mm.
The thickness of the adhesive layer is 0.1 mm-0.5 mm.
The adhesive layer is a polyurethane reaction type hot melt adhesive layer.
The processing technology of the copper-aluminum composite section comprises the following steps: deoiling and removing stains on the surface of an aluminum alloy substrate, drying and then placing on a bonding rolling device, uniformly spraying a polyurethane reaction type hot melt adhesive on the outer surface of the aluminum alloy substrate, wherein the width of a glue layer after glue spraying is larger than 5mm, the thickness of the glue layer after glue spraying is 0.1-0.5 mm, and the copper plate is bonded on the aluminum alloy substrate in a pressing manner at the running speed of the device of 5-6 m/min and the heating power of 8 KW.
The invention has the beneficial effects that: in the invention, the copper plate is glued on the aluminum alloy base material, and the copper plate has wear resistance and acid and alkali resistance, so that the wear resistance and the acid and alkali resistance of the copper-aluminum composite section are improved. Because of adopting the polyurethane reaction type hot melt adhesive layer, the bonding strength of the copper plate and the aluminum alloy section is increased. The detection shows that after the copper plate is glued for 72 hours, the glued part of the copper plate is pulled by hand pliers without falling off, the tearing strength is more than or equal to 2.5N/mm, the copper plate is coated on the aluminum alloy base material by taking points as surfaces without shearing in the processing process, and the problem of gluing the copper plate on the irregular circular arc and the concave-convex lines of the corners is solved. The copper door and window decorated by the copper-aluminum composite section bar has various bright lines and can reach corresponding processing precision.
