Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a production process of a novel heat-insulating pouring electrophoretic aluminum profile structure, which avoids the chemical adhesion between the non-polar film-forming resin coating and the polyurethane heat-insulating glue injection. The problem of poor bonding and physical bonding performance makes the gel-injected electrophoresis profile designed with this structure fully meet the national standard testing requirements

Embodiment Construction
[0024] Such as figure 1 and image 3 Shown, the production technology of a kind of novel heat-insulating casting type electrophoresis aluminum profile structure of the present invention; It comprises the following steps:
[0025] S1: extruded end face profile: extruded profile 1, the obtained profile 1 has a glue injection groove 2 sealed by the sealing profile 3;
[0026] S2: surface treatment: in step 1, the outer surface of the profile 1 with the closed glue injection tank 2 is fully electrophoretic painted;
[0027] S3: profile tearing: tear off the sealing profile 3 that seals the glue injection tank 2 with clamps such as pliers, and obtain the glue injection tank 2 without electrophoretic paint coating on the inner wall;
[0028] S4: Profile glue injection: inject glue into the glue injection groove 2 that has no electrophoretic paint coating on the inner wall.
[0029] Through the combined use of the ingot cylinder and the extrusion die, a glue injection tank 2 with...

The invention relates to the field of a production process of an aluminium alloy section, in particular to a production process of a novel heat insulation cast electrophoresis aluminium section structure. The production process comprises the following steps: S1, squeezing an end face section, i.e. squeezing a section and enabling the obtained section to be provided with a glue injection groove sealed by a sealing section; S2, carrying out surface processing, i.e. carrying out comprehensive electrophoretic coating on the outer surface of the section with the sealed glue injection groove in the step S1; S3, carrying out section tearing, i.e. tearing off the sealing section which seals the glue injection groove by a fixture such as a plier so as to obtain the glue injection groove of which the inner wall is not provided with an electrophoretic coating layer; S4, carrying out section glue injection, i.e. injecting glue into the glue injection groove of which the inner wall is not provided with the electrophoretic coating layer. Adoption of the process disclosed by the invention avoids the problems of both poor chemical adhesion and physical adhesion between a film forming resin coating which is of a nonpolar structure and polyurethane thermal insulation glue , enables the glue injected electrophoresis section adopting the structural design to completely accord with each detection requirement of the national standard and provides powerful guarantee for competition of the aluminium alloy heat insulation section coated with the electrophoretic coating in the aluminium alloy market.
Description
technical field [0001] The invention relates to the field of production technology of aluminum alloy profiles, in particular to a production process of a novel heat-insulating pouring electrophoretic aluminum profile structure. Background technique [0002] With the rapid development of aluminum alloy doors and windows, various surface treatment methods have emerged one after another. Aluminum alloy profiles coated with electrophoretic paint are gradually favored by customers in the insulation door and window market due to their superior aesthetics and weather resistance. However, electrophoretic profiles are used The various performances of cast heat insulation can not meet the requirements of GB5237.6-2012, this problem has been plagued by the development of electrophoretic aluminum alloy profiles. [0003] There is a layer of electrophoretic paint on the surface of electrophoretic aluminum alloy profiles, such as figure 2 Shown is a cross-sectional structural diagram of ...
