Description

Preparation process of thermal transfer printing type wood grain-like iron door sill
Technical Field
The invention relates to the field of household production, in particular to a preparation process of a thermal transfer printing type wood grain-like household door sill.
Background
The wood-imitating process is one kind of decoration technology used in building decoration and can produce various products similar to solid wood. The product manufactured by the wood-imitation process has the visual effects of wood-imitation and real wood products which are different from each other in appearance, can be just like a fake, even difficult to distinguish, and achieves a very good decorative effect.
Aluminum spraying building sections sold in the market, aluminum spraying furniture and other daily-use steel spraying ornaments are more and more difficult to meet the aesthetic requirements of decoration of people due to the single color of the sprayed coating. Some manufacturers paste the image-text transfer film on the metal spraying piece by using glue, and then heat the metal spraying piece to transfer the image-text onto the metal spraying piece, but the heat transfer technology in the market adopts a preparation process of vacuum heat transfer plane textures, so that the limitation is that only regular sections or planes can be operated and processed, the process cannot be used for processing household products with more irregular curved surfaces due to the limitation of vacuum adsorption, and most of the processes are directed at aluminum sections, and the section is selected singly.
There is a related report that a thermal transfer process is proposed, in which a pattern is designed, then ink is uniformly applied on a thermal transfer film to form a pattern according to a set target pattern using a coating machine, and the pattern is transferred onto glass using a thermal transfer machine. For example, the document with the patent application number of CN201110410452.3 discloses a hollow glass brick thermal transfer coating and a thermal transfer process, wherein the manufacturing process comprises the following steps: coating a high-gloss transparent coating and a white coating on the surface of the hollow glass, preparing a base material or printing a digital image on a paper base material or a high-molecular film by using thermal sublimation ink, and performing vacuum-pumping packaging by using an aluminum foil bag and a silica gel tape to combine the hollow glass brick needing thermal transfer printing with the printed or printed base material to perform image transfer printing by using heating and baking equipment; the full-color digital image is transferred to the hollow glass brick in a thermal transfer printing process mode by coating the thermal transfer printing coating with high adhesiveness, good weather resistance and low energy consumption on the hollow brick glass, so that the pattern on the transfer printing paper can be perfectly transferred to the glass brick; however, in the thermal transfer process, the ink of the pattern is transferred to the hollow glass brick through natural sublimation, cannot be sufficiently adsorbed on the surface of the glass, is poor in stereoscopic impression, and is easy to fade. The problem that the thermal transfer printing image cannot be fully adsorbed on the surface of the household section bar also exists for household products with a large number of different curved surfaces.
Disclosure of Invention
In order to solve the problems, the invention provides a preparation process of a thermal transfer printing type wood grain-imitated iron door sill, which is suitable for iron household sectional materials with more special-shaped curved surfaces, and the thermal transfer printing image is fully adsorbed on the surface of a household product and has strong adhesion firmness.
The technical scheme provided by the invention is that the preparation process of the thermal transfer printing type wood grain-like iron door sill comprises the following steps:
s1, after welding the pipe fitting, pretreating the pipe fitting by using a phosphating coating agent, drying and polishing to obtain a pretreated part;
s2, electrostatically spraying plastic powder on the surface of the pretreatment part, solidifying at 195-minus 205 ℃, and cooling to form a thermoplastic coating to obtain a plastic spraying treatment part;
s3, adhering the thermal transfer paper to the surface of the plastic spraying treatment piece by using an adhesive, performing thermal transfer treatment at 160-240 ℃, and tearing off the thermal transfer paper after the thermal transfer paper is completely cooled to obtain the thermal transfer type wood grain-like door sill.
Preferably, the molding powder comprises the following components in parts by weight: 30 parts of epoxy resin, 1.8 parts of methyl ester, 20 parts of titanium dioxide, 16 parts of barium sulfate, 10 parts of flatting agent, 0.2 part of benzoin and 25 parts of pigment.
Preferably, the pigment comprises 24 parts of ultramarine, 0.05 part of imported blue and 0.05 part of iron yellow.
Preferably, the adhesive comprises the following components in parts by weight: 50-70 parts of polyester polyol, 0.5-2 parts of cross-linking agent and 5-10 parts of propylene oxide propylene ether.
Preferably, the pipe fitting is an iron pipe fitting, and the iron pipe fitting comprises at least one special-shaped curved surface.
Preferably, the cross-linking agent comprises one or more of gamma-glycidoxypropyltrimethoxysilane, gamma-aminopropyltriethoxysilane and polyethyleneimine acrylic polymers.
Preferably, the step S2 further includes maintaining the temperature for 20-30 minutes after curing.
Preferably, the step S3 further includes maintaining the temperature for 20-30 minutes after the thermal transfer process.
Preferably, the step S1 further includes removing oil by using alkaline soaking after the pipe fitting is welded, and removing rust by using acid soaking.
The scheme utilizes the action of heat energy to separate the ink layer from the paper/film and transfer the pattern to a printing stock to finish transfer printing, and the principle is that the ink on the transfer paper/film permeates into the thermoplastic coating by the sublimation solid-gas phase transfer → permeation → desublimation adsorption coloring. When the temperature is reduced and the image is desublimated, the image is completely transferred to the coating.
It is worth noting that in the scheme, the propylene oxide propylene ether in the adhesive participates in the curing reaction of the molding powder together to form a part of a cross-linked resin molecular structure, so that the thermal transfer printing film and the molding powder are fused, the thermal transfer printing image is ensured to be fully adsorbed on the surface of a household product, and the method is suitable for processing household products with more irregular curved surfaces.
The invention has the beneficial effects that:
1. according to the scheme, the molding powder is used for spraying and processing the surface of the home, so that the heat transfer film is fully combined with the special-shaped curved surface of the product;
2. the scheme uses the combination of the molding powder and the binder to replace a vacuum adsorption process in the traditional process, overcomes the defect that the vacuum adsorption process is not suitable for household products with more special-shaped curved surfaces, ensures that the heat transfer printing of the product is heated more uniformly and the adhesion of the special-shaped surface of the household product is firmer without vacuum wrapping outside the product;
3. the propylene oxide vinyl ether in the adhesive participates in the curing reaction of the epoxy resin in the plastic powder, so that the thermoplastic layer and the adhesive form a mutually-interpenetrating network structure, and the bonding degree is higher;
4. the adhesive and the molding powder both use methyl ester as a common component, so that the fusion property of the thermoplastic coating and the thermal transfer paper is improved.
