preparation example Construction

[0019] As mentioned in the background technology, the flatness of PVC film materials in the existing decoration material market is relatively low, and the hand feeling is not delicate enough to meet the defects of high-end decoration requirements. In a typical embodiment of the present invention, a A method for preparing a PVC decorative film, the preparation method comprising: step S1, using a first anilox roller of 100-300 mesh to roll-coat a bridging agent on a PVC fabric to obtain a primer film; step S2, using a first anilox roller of 100-300 mesh The second anilox roll coats the water-based PU slurry on the primer film to obtain a PVC decorative film.

[0020] In the above-mentioned preparation method of the present invention, the anilox roll of specific mesh is carried out the bridging agent roller coating, and the surface treatment mode that the anilox roller of specific mesh carries out the water-based PU paste roller coating of combination, not only helps to control ea...

Embodiment 1

[0039] Surface treatment is carried out on the PVC fabric containing the three-layer structure of the bottom layer, the surface layer and the back coating, and the thickness of the PVC fabric is 0.10mm.

[0040] First, a 100-mesh anilox roller is used to roll-coat the bridging agent on the PVC fabric, and after the roller coating, place it in hot air at 40°C for drying to obtain a primer film.

[0041] Then use a 150-mesh anilox roller to roll-coat water-based PU slurry on the bottom coating film, and the obtained water-based PU layer will be dried in hot air at 35°C after roller coating, and then the entire PU-PVC composite film after drying The embossed layer is processed to obtain a PVC decorative film.

Embodiment 2

[0043] Surface treatment is carried out on the PVC fabric containing the three-layer structure of the bottom layer, the surface layer and the back coating, and the thickness of the PVC fabric is 0.80mm.

[0044] First, a 300-mesh anilox roller is used to roll-coat the bridging agent on the PVC fabric, and after the roller coating, place it in hot air at 60°C for drying to obtain a primer film.

[0045] Then use a 300-mesh anilox roller to roll-coat the water-based PU slurry on the bottom coating film. After the roll coating, place it in hot air at 110°C for drying, and then emboss the entire PU-PVC composite film layer after drying. , to obtain a PVC decorative film.

Abstract

The invention provides a PVC decorative film and a preparation method thereof. The preparation method includes: step S1, using a first anilox roller of 100-300 mesh to roll-coat a bridging agent on the PVC fabric to obtain a primer film; step S2, using a second anilox roller of 100-300 mesh to coat the primer film Water-based PU slurry is applied to the upper roller to obtain a PVC decorative film. The preparation method improves the adhesion between the water-based PU slurry layer and the PVC fabric layer, and also improves the coating uniformity and surface compactness of the water-based PU slurry layer, thereby improving the wear resistance and durability of the prepared PVC decorative film. Scratchability, surface smoothness and smoothness, and make the prepared PVC decorative film have a satin-like skin texture, thus meeting the market demand for high-end home decoration film materials.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a PVC decorative film and a preparation method thereof. Background technique [0002] In the existing decorative materials market, as consumers' awareness of environmental protection increases, the requirements for materials are becoming more and more stringent. At present, PVC film is the most widely used material, including monochrome film, imitation wood grain film, high photosensitive film, etc. Although these films can meet the performance requirements of most home decoration, there are still deficiencies in surface smoothness and gloss. , For example, the surface of the film feels relatively rough, which is difficult to meet the needs of the high-end home improvement market. [0003] Therefore, there is still a need to improve the prior art to provide a decorative film material with high flatness and fine touch. Contents of the invention [0004] The main purpose of ...
