Description
Technical field
The present invention relates to aluminium alloy extrusions production technology field, particularly a kind of production technology of novel heat-insulation cast-type electrophoretic aluminium section structure.
Background technology
Follow the fast development of aluminum heat insulation door and window, various surface treatment modes emerge in large numbers in succession, the aluminium alloy extrusions of electrophoretic paint application obtains gradually client's favor with its superior aesthetics and weatherability on Thermal insulation door and window market, but the requirement that electrophoresis section bar adopts the various performances of pouring-type heat-insulation not reach GB5237.6-2012, this problem is perplexing the development of electrophoresis-type aluminium alloy extrusions always.
Electrophoresis-type aluminium alloy section surface has one deck electrophoretic paint, as shown in Figure 2, is the cross section structure figure of the electrophoretic aluminium section of prior art, and in process, section bar body all will plate one deck electrophoretic paint on 1 surface, then gives the interior injection adiabatic gum of injecting glue groove 2.Because be carries out injecting glue after the electrophoretic paint that first carries out section bar body 1 is electroplated processing again in injecting glue groove 2, on injecting glue groove 2 inwalls, must first there is one deck electrophoretic paint layer, and the film-forming resin of electrophoretic paint coating presents nonpolar structure, and chemical adhesive and physics adhesive property between the heat insulation injecting glue of polyurethane are all very poor, the electrophoresis-type section bar Performance Detection that has therefore caused cast style to produce does not reach international standard.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of production technology of novel heat-insulation cast-type electrophoretic aluminium section structure, this technique has avoided being all very poor problems of the film-forming resin coating of nonpolar structure and the chemical adhesive between the heat insulation injecting glue of polyurethane and physics adhesive property, makes to meet the every testing requirement of GB completely with the injecting glue electrophoresis section bar of this structure design.
For solving above-mentioned technical problem, the production technology of a kind of novel heat-insulation cast-type electrophoretic aluminium section structure of the present invention; It comprises the following steps:
S1: extruding edge profile: extrudate, the injecting glue groove that has sealed section bar to seal on the section bar obtaining;
S2: surfacing: the section bar external surface in step 1 with sealing injecting glue groove carries out comprehensive electrophoretic coating;
S3: section bar tearing notch: by fixtures such as pliers, the sealed sectional materials of shutting injecting glue groove is torn, obtain not having on inwall the injecting glue groove of electrophoretic paint coating;
S4: section bar injecting glue: to there is no injecting glue in the injecting glue groove of electrophoretic paint coating on inwall.
Further, the extrusion process of S1 medium section, for the heating of circle ingot casting, heats ingot-containing tube and extrusion die simultaneously; After having heated, quench successively, interruption, stretching, sawing, frame up, the procedure of processing of timeliness, improve intensity and the hardness of section bar.
Further, the process of electrophoretic coating described in S2 is followed successively by that pure water is washed, painted, pure water is washed, scalds, water is cut, electrophoresis, washing, liquid are cut, oven dry, blanking, check.
Further, before the electrophoretic coating operation described in S2, also increase and have anodised process, anodised process comprises check, material loading, degreasing, washing, alkali cleaning, washing, neutralization, washing, oxidation, washing.
Further, the fixture using in S3 can be nipper plier.
Further, the glue of noting in S4 is polyurethane adiabatic gum.
Adopt technique of the present invention, by being arranged on the sealed sectional materials on injecting glue groove, when electrophoresis is produced, because the sealed section bar of injecting glue notch is shut, electrophoretic paint can not electro-deposition in injecting glue groove, in injecting glue notch, there is no electrophoretic paint coating completely; Before injecting glue production link, sealed sectional materials is torn by fixtures such as pliers, carry out again injecting glue production, owing to there is no electrophoretic paint in injecting glue groove, all very poor problems of the film-forming resin coating of nonpolar structure and the chemical adhesive between the heat insulation injecting glue of polyurethane and physics adhesive property have been avoided being, make to meet the every testing requirement of GB completely with the injecting glue electrophoresis section bar of this structure design, for the competition of electrophoretic paint application heat insulated shape bar of aluminum alloy in aluminium alloys market provides strong assurance.
