Problems solved by technology

However, in the existing technical system, there are the following problems: First, the pattern can only be printed on the non-colorful layer by ordinary printing technology, and even the printing layer and the colorful layer will not be adjacent to each other, and other film layers are separated in the middle. , on the basis of the impact on the colorful effect, the bonding ability between layers is poor, and the rendering effect of the printed pattern is not good, and there will be problems such as pattern distortion or blurring due to the colorful
Second, after adding the printed film layer, the mechanical properties of the overall film will be greatly reduced due to the unevenness of the material in the film caused by the pattern in the printed film layer. During the process, problems such as delamination, light transmission / reflection performance reduction, etc. caused by stress such as stretching greatly reduce the service life of the product

Abstract

The invention discloses a manufacturing method of a colorful tpu material with patterns, and relates to the technical field of preparation of film materials with special structures, the method comprises the following steps: sequentially stacking and hot-pressing a printing layer film material, a hot melt adhesive film and a TPU film to obtain a composite film-1; coating a colorful liquid crystal material on the pretreated PET surface, and drying; coating a UV glue layer-2 on the surface of the colorful liquid crystal layer, and standing; coating the surface of the printing layer film material of the composite film-1 with a UV glue film-1, and standing; the two obtained UV glue surfaces are oppositely stacked, pressurized standing is carried out, and then light curing is carried out; stripping the PET layer, coating UV glue on the surface of the colorful liquid crystal layer, and standing; pasting a PU film on the surface of the UV glue, and carrying out illumination curing; the colorful tpu material with the pattern is obtained. According to the invention, through a specific process, the technology of adding the printed pattern into the glare film is adopted, so that the prepared colorful tpu material with the pattern has excellent mechanical property, glare effect and reflective property.

Description

technical field [0001] The invention relates to the technical field of preparation of special-structured film materials, in particular to a preparation method of a patterned colorful tpu material. Background technique [0002] With the continuous improvement of people's requirements for the quality of life, the requirements for the appearance of various products or their packaging have also increased. Therefore, colorful materials with beautiful appearance have received extensive attention in recent years, and further, colorful film materials The technology of pattern printing on the surface has also been developed. However, in the existing technical system, there are the following problems: First, using common printing technology, the pattern can only be printed on the non-dazzling layer, and even the printing layer and the dazzling layer will not be adjacent to each other, and there are other film layers in the middle. , On the basis of affecting the dazzling effect, the ...
