Problems solved by technology

[0003] 1. The surface coating is glossy paint, so there is a reflective effect on the surface of the thermal transfer steel plate, which will affect the use effect of the steel plate
[0004] 2. The embossing is embossed after the steel surface coating is cured at high temperature, the embossing is blurred, and it is easy to produce cracks and other defects when the steel plate is bent

Embodiment Construction

[0017] The invention discloses a continuous production method for a matte concave-convex thermal transfer printing steel plate. The technological process of the method consists of a coating unit, a plasticizing unit, an embossing unit, a curing unit and a thermal transfer printing unit.

[0018] 1. Coating unit:

[0019] The coating unit is to continuously transport the coil or sheet of the steel plate to be printed to the reverse coating roller to coat the matt surface coating. The coating unit adopts the two-roller reverse coating method. When coating the paint, the pick-up roller draws the paint from the paint pan, then transfers it to the coating roller, and then the coating roller coats it on the surface of the steel plate. Its structure is as follows: figure 1 .

[0020] The matt surface coating is that nylon powder is added to the polyester top paint, and the amount of nylon powder added is 10-50% of the weight of the polyester top paint.

[0021] Alternative applicat...

Abstract

A technology for continuously producing the dull multi-color steel sheet with concave-convex pattern includes such steps as continuously feeding steel sheet, reversely coating the dull surface paint, baking the surface solvent by hot air, blowing cold air to make its surface become non-adhesive, embossing by embossing roller to form concave-convex pattern, baking by hot air to solidify the paint, thermotransfer printing, with thermotransfer film and hot rubber drum, cooling by cold air, and removing used film.

Description

Technical field: [0001] The invention relates to a continuous production method of a thermal transfer printing steel plate, in particular to a continuous production method of a matte concave-convex pattern color steel plate. It belongs to the technical field of thermal transfer printing of steel plates. Background technique: [0002] Before the present invention was made, the traditional continuous production method of concave-convex thermal transfer printing steel plate was to first coat the surface coating on the surface of the steel plate substrate, and then press the concave-convex pattern on the surface of the steel plate after the coating is completely cured, and finally heat the steel plate. transfer printing. This law mainly has the following shortcomings: [0003] 1. The surface coating is glossy coating, so there is a reflective effect on the surface of the thermal transfer steel plate, which will affect the use effect of the steel plate. [0004] 2. The embossi...
