Problems solved by technology

Due to the large number of coatings and film layers in the preparation of composite high-gloss films, the interface bonding strength between coatings and film layers has a great influence on the comprehensive performance of composite high-gloss films, and the interface bonding strength obtained by general methods is low. Difficult to pass the main performance tests, such as cupping test performance, 100°C water boiling test performance, bending resistance performance, impact resistance performance and salt spray resistance performance and other technical indicators testing

Embodiment 1

[0029] refer to figure 1 and figure 2 As shown, the present invention includes the following process steps.

[0030] A PET wire drawing film 1 with wire drawing stripes on the surface is selected as the base film, with a thickness of 25±1 μm. The surface corona treatment of the PET wire drawing film is carried out by a film corona machine, and the arc discharge power of the film corona machine is set to 7000w to prevent the film from being broken down by the transitional corona and improve the surface tension coefficient of the film. After corona treatment, the surface tension coefficient is 52mN / m, which is conducive to improving the adhesion fastness of various coatings to PET wire drawing film. Use a coating machine to coat the surface of the PET wire drawing film with no wire drawing pattern adhesion promotion resin layer 2. The adhesion promotion resin has a non-volatile component content of 15%, a viscosity of 100 mPa s under standard conditions, and a coating speed ...

Embodiment 2

[0032] Use a coating machine to coat the surface of the PET wire drawing film 1 without the wire drawing pattern with an adhesion promotion resin layer 2. The adhesion promotion resin has a non-volatile component content of 10%, a viscosity of 85 mPa·s under standard conditions, and a coating speed of 60 m / min. , coating machine oven baking temperature 95 ℃, baking time 6s, glue amount 7g / m 2 , After winding, the aging temperature is 55°C, and the aging time is 48h. Anti-glare and anti-scratch coating 3 is coated on the surface of the adhesion promotion resin layer 2 by dimple coating method, the non-volatile component content of the UV photocurable resin containing anti-glare particles is 40%, and the viscosity is 160 mPa·s under standard conditions , coating speed 40m / min, coating machine oven baking temperature 110°C, baking time 13s, UV lamp ultraviolet radiation energy 400mj / cm 2 , the irradiation time is 2.0s, and the thickness of the anti-glare and anti-scratch coating...

Embodiment 3

[0034] The anti-glare and anti-scratch coating 3 is coated on the surface of the adhesion promotion resin layer by the dimple coating method. The non-volatile component content of the UV light-curable resin containing anti-glare particles is 55%, and the viscosity is 240 mPa·s under standard conditions. Coating speed 40m / min, coating machine oven baking temperature 120°C, baking time 13s, UV lamp ultraviolet radiation energy 380mj / cm 2 , the irradiation time is 2.0s, and the thickness of the anti-glare and anti-scratch coating is 4 μm. Anti-glare particles are SiO 2 Microparticles with a particle size of 4±1 μm. The UV light-curable resin is mixed with polyurethane acrylate resin, silicone acrylate resin and polyester acrylate resin in a mass ratio of 50:25:25wt%. Vacuum aluminum plating on the surface of the primer layer with a winding high vacuum coating machine to form a vacuum aluminum coating layer 5, and the vacuum degree of the coating machine is 6*10 -3 Pa, coating c...

Abstract

The invention provides a preparation method of an imitation metal wiredrawing composite high light film. The preparation method includes the steps of: selecting a PET wiredrawing film, performing a corona treatment on the surface of the PET wiredrawing film, coating an adhesion promotion resin layer on the surface of the PET wiredrawing film without wiredrawing stripes, coating a photocurable resin containing anti-dazzle particles on the surface of the adhesion promotion resin layer, forming an anti-dazzle scratch-proof coating after UV light irradiation, coating a polyurethane resin on the surface of the PET wiredrawing film as a primer agent layer, performing vacuum-plating aluminum on the surface of the primer agent layer with a winding vacuum coating device, coating a compound adhesive on the surface of the vacuum-plating aluminum layer, and compounding the PET wiredrawing film and the PVC film under heating and pressurizing condition. The composite high light film has a lifelike imitation metal wiredrawing pattern, and has good anti-dazzle effect and high composite intensity, is boiling-resistant and scratch-proof, and has wide application range.

Description

technical field [0001] The invention relates to a preparation method of a composite decorative film, in particular to a preparation method of a composite high-gloss imitation metal drawing film. Background technique [0002] The brushed stainless steel color plate used for home appliance panels and various decorative materials is expensive due to stainless steel materials, low production efficiency, low output, and single color, thereby restricting its wide application. The development and application of color steel plate made of composite high-gloss film imitating metal wire drawing and cold-rolled steel plate overcomes the limitations of high price, low output and single color of stainless steel wire drawing color plate, enriches product categories, and imitates metal wire drawing. Various, rich colors, beautiful and novel appearance, bring a brand-new visual impact to consumers, and greatly meet the market demand. [0003] The metal-like wire drawing composite high-gloss...
