Production process of novel heat insulation cast electrophoresis aluminium section structure

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.
