Aluminum plate heat transfer printing method

Abstract

The invention discloses an aluminum plate heat transfer printing method. The method comprises following steps: first, subjecting aluminum plates to a surface pre-treatment by a pickling machine to remove oil stains and dusts on the surfaces of the aluminum plates, then evenly painting a layer of transfer printing medium on each aluminum plate; placing aluminum plates, which have been each coated with a layer of transfer printing medium, in a oven to bake, controlling the temperature in the oven in the range of 180 DEG C to 200 DEG C and the baking time in the range of 10 seconds to 20 seconds; cutting the aluminum plates into a required size in a cutting machine, then cutting heat transfer printing papers or heat transfer printing films to be heat transfer printed according to the size of the aluminum plate, finally coating the heat transfer printing papers or heat transfer printing films on the aluminum plates, aligning four edges, placing the aluminum plates and the heat transfer printing papers or heat transfer printing films together on a thermocompressor to carry out a thermo-compressing treatment, and controlling the pressure of the thermocompressor of 55 kgf / m2, the temperature of 190 DEG C, and the thermo-compressing time of 18 seconds. The aluminum plate heat transfer printing method is capable of carrying out heat transfer printing on the surfaces of aluminum plates to make the surfaces of the aluminum plates have the effects of natural wood grain and stone grain, so the aluminum plates have the same decoration effects as those of natural wood material and stone material.

Description

technical field [0001] The invention relates to a thermal transfer method, in particular to an aluminum plate thermal transfer method. Background technique [0002] With the improvement of people's living standards, the requirements for interior decoration are getting higher and higher, and more and more people are beginning to pursue solid wood and natural stone decoration materials. With the development of the decoration industry, some natural precious wood and stone are becoming more and more popular. In order to prevent people from overuse, the government has begun to vigorously protect these wood and stone. In order to make the surface of decorative materials have the effect of real wood grain and stone grain, people have invented a thermal transfer technology, which can transfer various desired patterns on the surface of wood. However, the traditional thermal transfer technology is usually to transfer printing on the surface of wood. Since wood is not fireproof, and h...

Problems solved by technology

However, the traditional thermal transfer technology is usually to transfer printing on the surface of wood. Since wood is not fireproof, and has the disadvantages of being easily deformed and not moisture-proof, this kind of wood decoration material has gradually failed to meet people's needs. People began to look for a A decorative material that is not only beautiful, but also fire-proof, moisture-proof and deformation-proof

The aluminum plate has the characteristics of fire prevention, moisture resistance and deformation resistance, but currently there are very few designs and colors that can be transferred on the surface of the aluminum plate.

Moreover, even after successful transfer printing on the aluminum plate, it has a strong metallic luster, and some even have color difference, sweat spots, and different shades of color, which seriously affect the decorative effect.
