Method for preparing clinquant high molecular decorative film

Abstract

The invention relates to a method for preparing a clinquant high molecular decorative film. The decorative film is formed by tightly compounding a base material and a printed surface film, wherein the printed surface film is formed by tightly compounding three layers of materials, namely a printed film, a primitive color layer of golden yellow and a film surface layer of golden yellow, and the film surface layer of golden yellow is arranged on the inner layer of the decorative film and is directly and firmly stuck to the base material. The method comprises the following processing steps of: firstly, calendaring the base material; secondly, preparing the printed film; thirdly, printing the surface film; and fourthly, laminating. The method is characterized in that titanium white powder and fire retardant are added to the formula of the base material so as to achieve the opacity and the fire-retardant function of the base material, and simultaneously, the firmness of lamination is enhanced through the corona treatment. Besides, a great amount of valuable gold dust is saved by adopting the technology of secondary printing so that a little gold dust can be arranged on the surface of a printed layer without being laminated and covered by a thick ink layer. In addition, the fire retardant is added to the printed film so that both the interior and the exterior of the decorative film can achieve the fire-retarding function. As the color of golden yellow and the gold dust are sequentially printed, the decorative film has the same appearance effect with gold foil.

Description

(1) Technical field [0001] The invention relates to a preparation method of a gold-foil-like polymer decorative film. It belongs to the technical field of polymer decoration materials. (2) Background technology [0002] Before the present invention was made, the places that needed high-grade decoration were all solved with gold leaf veneer in the past. It mainly has the following deficiencies: [0003] 1. Because gold foil needs to be made of very expensive rare metal gold, its own price is high, and the processing fee for foil making is very high, so the cost is very high. [0004] 2. It is complicated and difficult to decorate the appearance with gold foil. [0005] 3. Gold foil is in the air for a long time, and the surface is easy to accumulate dust, which is not easy to clean, affects the brightness of the appearance, and is easy to be damaged. [0006] 4. Since gold foil is a valuable item, it is vulnerable to criminals. [0007] 5. Because the gold leaf is thin a...

Problems solved by technology

[0003] 1. Because gold foil needs to be made of very expensive rare metal gold, its own price is high, and the processing fee for foil making is very high, and the cost is very high

[0004] 2. The appearance decoration process with gold foil is complicated and difficult

[0005] 3. Gold foil is in the air for a long time, the surface is easy to accumulate dust, it is not easy to clean, affects the brightness of the appearance, and is easy to be damaged

[0006] 4. Since gold foil is a valuable item, it is vulnerable to criminals

[0007] 5. Because the gold foil is thin and not strong, the scope of use is limited, and it is not easy to use it on a large scale
