For example, the document whose patent application number is CN201110410452.3 discloses a hollow glass block thermal transfer coating and a thermal transfer process. Dye-sublimation ink is used to print digital images on paper substrates or polymer film substrates, and use aluminum foil bags and silicone belts to vacuumize and package hollow glass bricks that require thermal transfer printing. Combined with printed or printed substrates, heating and baking equipment To transfer the image; by coating the hollow brick glass with a heat transfer coating with high adhesion, good weather resistance, and low energy consumption, and then transfer the full-color digital image to the hollow brick by the heat transfer process. On the glass brick, the pattern on the transfer paper can be perfectly transferred to the glass brick; but in the thermal transfer process, the ink of the pattern is transferred to the hollow glass brick through natural sublimation, which cannot be fully adsorbed on the glass surface, and the three-dimensional Poor sense and prone to fading
For household products with more heterosexual curved surfaces, there is also the problem that the thermal transfer image cannot be fully adsorbed on the surface of the household profile

Abstract

The invention discloses a preparation process of a thermal transfer type imitation wood grain iron door fence. The preparation process comprises the following steps of S1, after pipe fittings are welded, pretreating is carried out by using a phosphating steam film agent, drying and polishing are carried out, and a pretreatment part is obtained; S2, plastic powder is electrostatically sprayed on the surface of the pretreatment part, the pretreatment part is cured at the temperature of 195-205 DEG C and then cooled to form a thermoplastic coating, and the plastic-sprayed treatment part is obtained; and S3, heat transfer printing paper is adhered to the surface of the plastic-sprayed treatment part by using an adhesive, heat transfer treatment is carried out at the temperature of 160-240 DEGC, the heat transfer paper is torn off after the heat transfer printing paper is cooled completely, and the thermal transfer type imitation wood grain iron door fence which is suitable for iron home profiles with more special-shaped curved surfaces is obtained. The heat transfer pattern is sufficiently adsorbed on the surface of the household product, and the adhesion firmness is high.

Description

technical field [0001] The invention relates to the field of home furnishing production, in particular to a preparation process of a thermal transfer imitation wood grain home door fence. Background technique [0002] Imitation wood technology is a kind of decoration technology commonly used in the field of architectural decoration. Using this technology, various products that look like solid wood can be produced. From the appearance of the products made by imitation wood technology, the visual effects of imitation wood and real wood products are comparable. [0003] Aluminum sprayed architectural profiles, aluminum sprayed furniture and other steel sprayed daily decorations sold on the market are more and more difficult to meet people's decorative aesthetic requirements due to the single color of the sprayed coating. At present, some manufacturers use glue to paste the graphic transfer film on the metal sprayed parts, and then heat it to transfer the graphic and text to th...
