Problems solved by technology

Many labels are required to stand the test of time, not to be deformed or faded for a long time, not to be worn out due to contact with solvents, not to be deformed and discolored due to high temperature, etc., so it is necessary to use a special material printing medium and wood grain transfer printing material to ensure these Features, general inkjet, laser printing technology is unable to achieve
[0004] In the existing technology, the hand-feeling wood grain thermal transfer technology is relatively immature, mainly because the hand-feeling wood grain production device is expensive, only vertical, and only one finished product can be produced at a time, the efficiency is very low, and the spraying is uneven. There are problems such as color difference, wood grain printing and background color are easy to fall off

Embodiment 1

[0034] A horizontal hand feeling wood grain metal thermal transfer printing process is characterized in that its production process includes the following steps:

[0035] S1 metal prototype pretreatment: use pure water to dedust the metal prototype, then carry out degreasing and chemical removal treatment in turn, and then still wash with pure water, go through chromium-free passivation treatment, and finally wash with pure water to complete the pretreatment ;

[0036] S2 baking: Put the pretreated metal prototype into the baking room for drying to remove the residual moisture on the surface and increase the surface adhesion;

[0037] S3 spraying: After the metal prototype material obtained in step S2 is blown and dust-removed with a blower, the material is hung, and the powder electrostatic spraying primer is carried out in the spray booth;

[0038] S4 curing: Send the metal prototype material sprayed with the primer in step S3 into the baking room, after curing at high temp...

Abstract

The invention relates to a horizontal hand feeling wood grain metal heat transfer printing process, and mainly solves the problems of high production cost of hand feeling wood grains, low efficiency of finished products, chromatic aberration and the like. The process comprises the following steps: (S1) pretreatment of metal original profiles: the metal original profiles are dedusted by purified water for oil removal, medicine removal and chromium-free passivation; (S2) baking: the cleaned metal original profiles are put in a baking room for drying; (S3) spraying: the air blowing and dust removing treatment is performed on the metal original profiles by an air blowing machine; then, the hanging is performed; and the metal original profiles enter a spraying room for powder electrostatic primer spraying; (S4) curing: primer-sprayed products are directly fed in the baking room for high-temperature curing; (S5) the step (S3) is carried out for primer spraying; (S6) the hand feeling wood grains are manufactured; (S7) paper through bags are used for packing; and (S8) the heat transfer printing is performed. The process is suitable for the technical field of heat transfer printing of metalhand feeling wood grains.

Description

technical field [0001] The invention relates to the technical field of thermal transfer printing, in particular to a horizontal hand-feeling wood grain metal thermal transfer process. Background technique [0002] With the development of the times and the improvement of living standards, people have higher and higher requirements for decoration, so the utilization rate of wood is also very high. The main reason is that people love wood grain. grain, so the amount of use is very large, but this also results in excessive felling of trees. At the same time, because wood processing is expensive and its grain is natural, it is impossible to modify its grain, so it is difficult to satisfy the corresponding customers. Unique wood The grain also makes the price of some wood very high, making it inaccessible to ordinary users, and there are problems such as high price. [0003] With the emergence of transfer printing technology, this situation is being alleviated. Because wood grain...
