Abstract

The invention relates to an aluminum profile, in particular to a thermal insulation aluminum profile with the surface carved with patterns. A manufacturing method of the thermal insulation aluminum profile with the surface carved with the patterns sequentially comprises the steps of preparation of a polyurethane thermal insulation glue component A and a polyurethane thermal insulation glue component B; manufacturing of the thermal insulation aluminum profile, wherein the component A and the component B are stirred according to the mass ratio of (6-8):1, then are poured into an aluminum profile groove moving at a speed of 0.15-0.2m / s and form the thermal insulation aluminum profile after standing and being cooled and solidified; preparation of modified powder coatings, wherein the mixture melts and is extruded out at the temperature of 130-140 DEG C, and then is cooled and broken to obtain the modified powder coatings; electrostatic spraying and solidification at the temperature of 100-120 DEG C for 10-18min; curving processing, wherein the patterns are carved in the curved surface and colored for the first time, particularly, hard anodizing is carried out in an electrolyte with the electric current density being 4-5 amperes per square decimeter and the temperature being 22-28 DEG C, and the electrolyte contains vitriol, acetic acid and a mixed solution formed by mixing glycolic acid and succinic acid according to the mole ratio of 1:1; the patterns are colored for the second time. The thermal insulation aluminum profile with the surface carved with the patterns has the dustproof and antibacterial performance, and is good in impact resistance, abrasion resistance and weather resistance, and high in 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...
