Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a thermal transfer printing processing method for pulp molding.
[ background of the invention ]
The heat transfer printing technology is a special printing technology which prints any image such as portrait, landscape and the like on a heat transfer printing film, heats the heat transfer printing film to a certain temperature within a few minutes by a heat transfer printing heating device, and realistically transfers the pattern color on the paper to the materials such as porcelain, glass, metal, plastic, cotton fabric and the like. The paper pulp molding is to use waste newspaper and paper box paper as main raw materials, pulp the paper by additives in a certain proportion, dehydrate and form the paper pulp by a special mold, and then prepare the finished product by drying, heat treatment, shaping and the like. With the enhancement of the environmental protection consciousness of people, packaging concepts such as environmental protection, simplification, recycling and the like begin to be accepted by the consumers of the young generation. The application of pulp molding to packaging is also rapidly developed, but the pulp molding has smooth surface different from the prior printing materials such as glass, textile, ceramic and the like, the pulp molding has uneven surface due to the limitation of raw materials and production process, uneven paper fluff floats on the surface, the pulp molding needs to be formed and then printed, and the traditional printing cannot realize the purpose.
[ summary of the invention ]
The invention aims to provide a thermal transfer printing processing method of paper pulp molding, which can effectively cover paper furs and can obtain better printing effect.
The purpose of the invention is realized as follows:
a thermal transfer printing processing method of pulp molding comprises the following steps: feeding, namely placing the pulp molding right below the transfer printing film; adhering, namely adhering the transfer printing film to the paper pulp molding with the adhering pressure being P; heating, namely heating the transfer printing film tightly adhered to the paper pulp mold, so that the temperature of the transfer printing film is raised to T; maintaining the pressure and the temperature, and keeping the pressure P and the temperature T for the time T; and (5) demolding, namely demolding the transfer film from the pulp molding.
In the above method for processing pulp molding by thermal transfer printing, the pressure P is 3 tons to 5 tons.
The heat transfer printing processing method of pulp molding is characterized in that the temperature T is 150-180 ℃.
The above-mentioned method for thermal transfer printing of pulp molding, wherein the time t is 1 second to 3 seconds.
The thermal transfer printing processing method of the pulp molding further comprises the following steps: F. and UV mould pressing treatment, namely carrying out UV mould pressing treatment on the aluminum plating layer of the transfer printing film.
Compared with the prior art, the invention has the following technical characteristics:
1. when the transfer printing film is tightly adhered to the paper pulp molding, the transfer printing film has better flexibility, so that paper feathers on the paper pulp molding can be effectively covered when the transfer printing film is tightly adhered to the paper pulp molding, and better printing effect can be obtained.
2. The adhesive layer on the transfer printing film is melted and attached to the paper pulp molding during heating, the stripping layer on the transfer printing film is separated during demolding, so that the aluminum plating layer and the coloring layer are kept attached to the adhesive layer on the paper pulp molding, and the base film layer is separated along with the transfer printing film, thereby effectively avoiding that part of paper fibers are pulled up due to the fact that the surface of the paper pulp molding is pulled during demolding.
3. The pulp molding itself is not as hard as glass, metal, etc., and therefore the pressure P is controlled in the range of 3 tons to 5 tons to effectively prevent deformation during transfer.
4. The package after transfer printing by the method of the invention is harmless, environment-friendly and recyclable.
5. The invention realizes package transfer printing on paper and plastic, so that the paper and plastic has decoration and description effects, thereby making products more attractive and descriptive and improving the sales value of the products.
[ detailed description ] embodiments
A thermal transfer printing processing method of pulp molding comprises the following steps: feeding, namely placing the pulp molding right below the transfer printing film; adhering, adhering the transfer printing film to the pulp molding tightly, wherein the adhering pressure is P (the pressure P is preferably 3 tons to 5 tons); heating, namely heating the transfer printing film molded by clinging to the paper pulp, so that the temperature of the transfer printing film is raised to T (the temperature T is preferably 150 ℃ to 180 ℃); maintaining the pressure and the temperature, namely maintaining the pressure P and the temperature T to the time T (the time T is preferably 1 second to 3 seconds); and (5) demolding, namely demolding the transfer film from the pulp molding.
The thermal transfer printing processing method of the pulp molding further comprises the following steps: F. and UV mould pressing treatment, namely carrying out UV mould pressing treatment on the aluminum plating layer of the transfer printing film.
The transfer printing film comprises a base film layer, a stripping layer, an aluminum coating layer, a coloring layer and an adhesive layer from top to bottom in sequence. When the transfer printing film is adhered to the paper pulp molding, the adhesive layer of the transfer printing film is adhered to the paper pulp molding, when the transfer printing film is heated to the temperature T and the pressure P is maintained for the time T, the adhesive layer is melted and completely adhered to the surface of the paper pulp molding, then the release layer is released, the stripping layer of the transfer printing film is separated, so that the base film layer can be integrally separated along with the transfer printing film, and the aluminum plating layer, the coloring layer and the adhesive layer are adhered to the surface of the paper pulp molding. The UV mould pressing treatment can be carried out in advance, and the effect of the transfer printing after the UV mould pressing treatment can have the effects of three-dimensional and embossment.
