Heat insulation break bridge aluminum profile electrophoresis japanning process

Abstract

The invention discloses a heat insulation break bridge aluminum profile electrophoresis japanning process. A heat insulation break bridge aluminum profile comprises an aluminum alloy profile on the inner side, a heat insulation aluminum alloy profile on the outer side, and heat insulation clamping grooves formed in the aluminum alloy profile on the inner side and the heat insulation aluminum alloyprofile on the outer side; and the aluminum alloy profile on the inner side and the heat insulation aluminum alloy profile on the outer side are spliced together through the heat insulation clampinggrooves. The heat insulation break bridge aluminum profile electrophoresis japanning process specifically comprises the steps of nanometer treatment, anodic oxidation, electrophoresis japanning, drying solidification and the like. Through the heat insulation break bridge aluminum profile electrophoresis japanning process, a formed paint film is about 12-15 [mu]m, the heat insulation effect of theheat insulation break bridge aluminum profile can be enhanced as the paint film has the properties of resisting heat, contamination, ageing and the like, and meanwhile, as the nanometer treatment andother treatment are conducted before electrophoresis japanning, the paint film is more even and compact, and the quality of products is improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile preparation, and in particular relates to an electrophoretic painting process for heat-insulating broken bridge aluminum profiles. Background technique [0002] Aluminum alloy has good thermal conductivity. If it is to be used as an efficient heat-insulating door and window frame, its structure needs to be fully optimized, so that the aluminum alloy door and window frame can have good thermal insulation performance while having inherent characteristics and advantages. The common practice in the industry is to install a heat insulation layer composed of heat insulation materials inside the aluminum alloy profiles to block thermal bridges and reduce thermal conductivity, thereby optimizing heat preservation and heat insulation effects. In the prior art, heat insulating materials are usually used to divide the aluminum alloy profile into two parts so as to achieve the purpose of heat insulat...
