Abstract

The invention relates to an aluminum profile, especially to a surface-carved thermally-insulating aluminum profile, which is successively prepared from the following steps: preparation of a componentA and a component B of a polyurethane heat-insulation adhesive; preparation of thermally-insulating aluminum profile: stirring the component A and the component B according to the mass ratio of 6-8:1and pouring into an aluminium profile groove moving at the speed of 0.15-0.2 m / s, standing, cooling and solidifying to form the thermally-insulating aluminum profile; preparation of modified powder coating: carrying out melt extrusion at 130-140 DEG C, cooling and crushing to obtain the modified powder coating; carrying out electrostatic spraying, and solidifying at 100-120 DEG C for 10-18 min; carving treatment: carving on the carved surface; first coloring: hard anodic oxidation is carried out in an electrolyte with the electric current density of 4-5 amperes / square decimeters and the temperature of 22-28 DEG C, and the electrolyte contains sulfuric acid, acetic acid, and mixed liquor mixed by glycolic acid and succinic acid at the molar ratio of 1:1; and second coloring. The product ofthe invention has dustproof and antibacterial properties, impact resistance, wear resistance, good weatherability and high glossiness.

Description

technical field [0001] The invention relates to an aluminum profile, in particular to a heat-insulating aluminum profile with carved patterns on the surface. Background technique [0002] Heat-insulating glue aluminum profile is a new type of building material. It is a composite material with heat insulation and sound insulation functions made of low thermal conductivity non-metallic materials connected with aluminum alloy building profiles. In addition to its structural strength properties as a building profile, it also has excellent thermal insulation and sound insulation properties. The principle is to use plastic profiles to separate and tightly connect the indoor and outdoor two-layer aluminum alloy into a whole to form a new heat-insulating aluminum profile. This innovative structural design takes into account the advantages of both plastic and aluminum alloy materials. Advantages, while meeting various requirements for decorative effect, door and window strength and...
