JPH06255061A - Production of decorative sheet - Google Patents

Abstract

PURPOSE:To produce a decorative sheet so as to develop the same effect as conventional one by a small quantity of a release agent. CONSTITUTION:An ink layer or a pattern ink layer is provided on a base material film if necessary and an electron beam curable resin is applied to the ink layer while a release agent is applied to the other film and the coated surfaces of both films are bonded under pressure and irradiated with electron beam to cure the electron beam curable resin to transfer the release agent to the surface of the electron beam curable resin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a decorative sheet for use on surfaces of furniture, articles and interior materials of buildings.

[0002]

2. Description of the Related Art Conventionally, a decorative sheet used for the above purpose is one in which a solid ink layer and a pattern ink layer are provided on a base material as needed, and an electron beam curable resin is mixed with a release agent. It was applied and then cured by irradiation with an electron beam.

This method of applying a release agent mixed with the electron beam curable resin has a problem that a large amount of expensive release agent is required because the distribution of the release agent is uniform. .

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to make a decorative sheet having the same effect as a conventional one with a small amount of a release agent. It is to provide a manufacturing method of.

[0005]

In order to solve this problem, the present invention provides a base film with a solid ink layer or a pattern ink layer, if necessary, and applies an electron beam curable resin. On the other hand, a release agent is applied on another film, the coated surfaces of both films are pressure bonded, electron beams are irradiated to cure the electron beam curable resin, and the release agent is applied to the surface of the electron beam curable resin. There is provided a method for producing a decorative sheet, which comprises:

The present invention will be described in detail below. As the base film according to the present invention, paper, various films, non-woven fabric, etc. can be used.

It is also preferable to optionally provide a solid ink layer or a pattern ink layer on the substrate film in the present invention. As a method of providing these layers,
There are gravure and gravure offset.

As the electron beam curable resin according to the present invention,
Urethane acrylate, polyester acrylate, epoxy acrylate, etc. can be used. Examples of the coating method include a roll coater, a gravure coater, a reverse coater, a knife coater and the like. Application amount is 7-20g /
m ² is preferred.

Silicon acrylate, fluorine acrylate, silicone resin, fluorine resin and the like can be used as the release agent in the present invention, and polyethylene terephthalate and the like can be used as the film to be applied. As a coating method, there are a micro gravure coater, a spray coater and the like. Coating amount is 0.1-0.2g / m ²
Is preferred.

As a method for press-bonding the coated surfaces of both films in the step of the production method of the present invention, wet lamination can be used, and the speed thereof is 30 to 100 m / se.
c, and the pressure is preferably 1.0 to 6.0 Kgf / cm ² .

Irradiation of an electron beam in the manufacturing method of the present invention,
About the curing of the electron beam curable resin, 200 Kv, 3 ~
Irradiation with an electron beam of 5 Mrad is preferable.

[0012]

As described above, according to the method for manufacturing a decorative sheet of the present invention, the slip agent is produced in a smaller amount than when it is mixed with the resin due to the concentrated presence of the expensive release agent on the surface. Further, since the surface of the electron beam curable resin is covered with a film coated with a release agent at the time of electron beam irradiation, it also has the effect of protecting the surface.

[0013]

[Example] A solid ink and a wood grain pattern ink were printed on a thin paper having a basis weight of 30 g / m ² , and a polyester acrylate resin was applied on this surface by a roll coater at 7 g / m ² . A 12 μm thick PET film is coated with a release agent of 0.1 μm.
g / m ^{2 was} applied. Immediately crimp these to 200K
It was cured by irradiating with an electron beam of eV and 3 Mrad. The PET film of the decorative sheet thus obtained was peeled off to transfer the release agent to the surface of the polyester acrylate on the thin paper side. This decorative sheet had excellent solvent resistance, abrasion resistance and the like, and had good surface smoothness.

[0014]

EFFECTS OF THE INVENTION The decorative sheet of the present invention is economical and solvent-resistant because the slip agent is produced in a smaller amount than when it is mixed with a resin because the expensive release agent is concentrated on the surface.
Good results are also shown in physical properties tests such as abrasion resistance, and surface smoothness is also good. Further, in the manufacturing method, the work of peeling off the film does not necessarily have to be performed in-line and can be peeled off in a later step, so that the film has an effect of protecting the surface.
