Problems solved by technology

However, because the paint film obtained by a single roller is thin and has roller marks on the surface, its surface effect is still not ideal, and it cannot meet people's increasingly higher requirements for decorative materials, especially in recent years. The emergence of metal decorative panels has a great impact on the plastic decorative panel market, but due to the high cost of film-coated metal decorative panels, it can only meet the needs of a small number of people. The preparation method of the effect plastic decorative board is extremely important

Embodiment 1

[0037] Embodiment 1: Preparation of plastic decorative board by curtain coating light-curing varnish

[0038] Plastic substrate: the surface layer is a single color (such as pure white, dark blue) or a simple color stripe pattern formed by a mixed extrusion process

[0039] First use an electrostatic induction rod to eliminate the static electricity on the surface of the plastic board, then use a dust removal device to remove the dust on the surface of the plastic board, and then use ethanol to wipe off the oil on the surface of the plastic board. The surface-treated plastic plate is sprayed with light-cured varnish on the flow coater through the belt conveyor. The temperature of the feed tank of the flow coater is 55°C, the transmission speed is 80 m / min, and the thickness of the light-cured coating on the surface of the plastic plate is 60-80um. Leveling under infrared at a temperature of 50°C for 20 seconds, entering a light curing machine equipped with three 5kw ultraviole...

Embodiment 2

[0040] Embodiment 2: Preparation of plastic decorative board by curtain coating light-cured metal flash coating

[0041] Plastic substrate: the surface layer is a single color (such as pure white, light blue) or a simple color stripe pattern formed by a mixed extrusion process

[0042] First use a static induction rod to eliminate the static electricity on the surface of the plastic board, then use a dust removal device to remove the dust on the surface of the plastic board, and then use isopropanol to wipe off the oil on the surface of the plastic board. The surface-treated plastic plate enters the flow coating machine through a belt conveyor, and is flow-coated with a light-curing metal flash coating mixed with 0.1wt% aluminum powder in the light-curing varnish. The temperature of the feeding tank of the flow coating machine is 50 ° C, and the transmission speed is 80 m / min. The thickness of the light-cured coating on the surface of the plastic plate is 60-80um. Leveling un...

Embodiment 3

[0043] Example 3: Preparation of printed plastic decorative boards by curtain coating with photocurable varnish

[0044] Plastic substrate: pure white plastic board

[0045]First use a static induction rod to eliminate the static electricity on the surface of the plastic board, then use a dust removal device to remove the dust on the surface of the plastic board, and then use isopropanol to wipe off the oil on the surface of the plastic board. Monochrome or color patterns are printed on plastic plates by gravure printing. The ink used for printing patterns is self-drying solvent-based ink, and the printed plastic plates are dried by hot air. The plastic plate printed with patterns is sprayed with light-curing varnish on the flow coating machine through the belt conveyor. The temperature of the feeding tank of the flow coating machine is 50°C, the transmission speed is 90 m / min, and the thickness of the light-curing coating on the surface of the plastic plate is 60-80um. Level...

Abstract

The invention pertains to the decorative plastic panel for building domain, especially relates to the method for producing panel by light solidifying coating in the surface. The invention cleans up backing plastic panel in the way of drenching, spraying or several roller coatings to coat light solidifying coating, then infrared advectes and light solidifies it. The invention is provided with the advantage of small producing field, low equipment investment, high production efficiency, low energy consumption and no contamination. The decorative plastic panel produced by such way is provided with not only attractive mirror effect, but also anti-fish tail, resistance to aging, easy to clean and non-inflammability because of its technique of drenching, spraying or several roller coatings to coat light solidifying coating in the surface.

Description

technical field [0001] The invention belongs to the field of plastic decorative boards for buildings, and in particular relates to a preparation method for producing plastic decorative boards by coating light-curing paint on the surface. Background technique [0002] Plastic panels used for decoration in the construction industry are generally extruded from polyvinyl chloride (PVC for short) plus a certain amount of pigments and fillers after melting, commonly known as PVC gussets. At present, plastic decorative boards are divided into two types. One type is used directly after being extruded by a plastic molding machine. This type of plastic decorative board has no decorative layer and protective layer on the surface, which not only lacks aesthetic feeling, but also the surface is easily scratched when used. Short life. The other is that there are decorative patterns and protective layers on the surface of the plastic decorative board. The decorat...
