Embodiment 1

[0079] like figure 1 and figure 2 The aluminum veneer for curtain wall comprises a main body 1 and an anti-rust decorative layer 2 sprayed on the outer surface of the main body 1. The anti-rust decorative layer 2 includes a primer 21 sprayed outwards from the side close to the main body 1, overcoated on the primer The top paint 22 on the top paint 21 and the finish paint 23 that is coated on top paint 22 surfaces again.

[0080] The processing technology of aluminum veneer includes the following steps,

[0081] Step 1: Cutting the material, using a shearing machine to cut the aluminum veneer to obtain the main body 1; the specification of the main body 1 in this application document is 600mm*1200mm*2mm;

[0082] Step 2: Punching, cutting corners and punching holes on body 1;

[0083] Step 3: Bending, use the bending machine to fold the edge of the body 1, the height of the edge is 10cm; the structure after bending is shown in image 3 shown;

[0084] Step 4: Welding, usi...

Abstract

The invention relates to a processing technology of an aluminum veneer for a curtain wall, and relates to the field of curtain wall materials. The processing technology solves the problems that the existing aluminum veneer and coatings are insufficient in binding force and the coatings are easy to fall off are solved. The processing technology specifically comprises the following steps of cutting-punching-bending-weld joint grinding-surface grinding-surface pretreatment-spray coating-drying; the surface pretreatment comprises degreasing, pickling and passivation; and the spray coating comprises priming, finishing coating and finish-coat painting. According to processing technology, in the degreasing process, a degreasing agent selected has an excellent degreasing effect, and grease can beadsorbed in the degreasing process, so that quantity of the grease with which the aluminum veneer is coated is reduced in a flushing process; the degreasing process is matched with pickling operation,the grease can be removed as much as possible, the aluminum veneer is good in degreasing effect, so that viscosity fastness of a primer can be increased when the priming is conducted; and the primer,the finish coat and finish-coat paint are connected tightly, and therefore paint layers of the finally generated aluminum veneer do not easily fall off.

Description

technical field [0001] The invention relates to the field of curtain wall materials, in particular to a processing technology of an aluminum veneer for curtain walls. Background technique [0002] Aluminum veneer curtain wall is a form of curtain wall. Nowadays, the development of aluminum veneer in my country is mostly applied to walls that need to be shaded and walls that do not receive light. Because traditional glass curtain walls often cause optical pollution, single-layer aluminum veneers are widely used abroad. [0003] As a new type of material, aluminum veneer is more and more widely used in construction, and more and more people have begun to realize the advantages of aluminum veneer. [0004] The existing authorized notification number is the Chinese patent of CN2658277Y, which discloses a ceramic aluminum veneer building decoration material, the aluminum plate is the base material, and the decorative surface layer of the aluminum plate base material is obtained ...
