Problems solved by technology

However, although the method described in this patent can improve the efficiency of spraying and the quality of the film layer, it cannot fundamentally change the disadvantages of the powder spraying process, the pollution caused by dust to the environment, and the inhalation damage caused by powder spraying workers. , and the appearance color that can be achieved by powder spraying is relatively single, which cannot meet the user's requirements for beautiful appearance and fine texture

Embodiment 1

[0024] 1. Preparation of PET wire drawing film

[0025] ①Take a roll of PET film, and the PET base film is purchased from Toray, Korea. Light transmittance: 92%, the level is optical grade, the thickness is 25μm, and the width is 1250mm. Use precision coating equipment to coat a layer of adhesion promoter on the surface of PET. The selected accelerator is a solvent-based accelerator with a solid content of 20 %, the thickness is 1μm, and it has good adhesion with UV glue.

[0026] ②: Use sophisticated UV transfer molding equipment to produce and prepare drawing PET film, select special UV glue, and buy it from Zhejiang An Ruisen Company. The mold is a special self-made vertical grain drawing mold. The molding temperature is controlled at 50°C, and the production line speed is controlled at 10m / min.

[0027] ③: The thickness of the UV-drawn layer of the prepared drawn PET film is 6 μm, the hardness is 2H, and the drawing touch is obvious.

Abstract

The invention discloses a preparation method and use of a black brushed composite film. The preparation method comprises coating one surface of a PET film coil with an adhesion promoter through a precision coating machine, coating the surface of the adhesion promoter layer with UV glue through an UV precision coating machine, carrying out transfer to obtain a PET brushed film, compounding the PETbrushed film and a black PVC film through compounding glue and carrying out aging treatment to obtain the black brushed composite film. The black brushed composite film is composed of a PET film and aPVC film, has excellent barrier properties, effectively reduces the corrosion of water vapor and oxygen to the surface of the steel plate through covering the steel plate surface, improves the corrosion resistance of the steel plate and prolongs a service life.

Description

technical field [0001] The invention belongs to the technical field of TV backplanes, and in particular relates to a preparation method and application of a black wire drawing composite film. Background technique [0002] TV is one of the most important household appliances in family life. Usually, the main material of the back panel of a TV is engineering plastics, and back panels of various sizes and shapes are prepared through thermoplastic molding. With the continuous development of display technology in recent years, some large-size TV sets have emerged as the times require. While the size has increased, the thickness of the TV set has also continued to decrease, which requires a high-strength backplane to support The entire fuselage is supported and protected. Obviously, plastic backplanes can no longer meet such requirements, and more and more manufacturers have begun to use metal plates as the main material for TV backplanes. [0003] CN105436051A discloses an aut...
