Description

Transparent decoration material using plastic and method of preparing the same}

The present invention in consideration of light weight and stability in the method of directly printing, transfer printing or decorative film on the back of the existing glass material in consideration of the light weight and stability, instead of glass by replacing the plastic material of the pre-treated thick film and the stability and processing occurring when using the glass and The present invention relates to a transparent decorative material using a plastic material that can prevent damage caused in transportation, transportation, and the like, and to reduce its weight.

In general, direct printing on the back of glass is common, but studies are being conducted to replace it with plastic in consideration of safety, processability, and processability of glass.

When the glass is replaced with plastic, not only the deformation of the plastic material occurs due to the conditions required during the drying and curing of the printing, but also the deformation of the ink itself, and in the case of the direct printing, the appearance of various patterns is difficult. .

In addition, due to the characteristics of general plastic materials, it is weak to scratches and is highly likely to cause warpage or discoloration.In the case of long-term storage, heat loss of plastic generally occurs, and air bubbles, etc. are printed on the film printed or adhered to the back side. Voids occur.

In addition, adhesives are used to attach various patterned film layers. In the case of adhesives, adhesive strength decreases due to aging and deterioration when left for a long period of time, and is exposed to the migration problems of plastics mentioned above. It is one of the main causes.

Therefore, the present invention provides a transparent decorative material and a method of manufacturing the same using a plastic having the same transparency as the existing glass material, and can continuously maintain the adhesive force even when left for a long time, and does not generate bubbles. There is a purpose.

In order to solve the above problems, in the present invention, it is possible to suppress the high temperature heat loss of the plastic material by introducing an anti-migration pretreatment process to the existing plastic material, and to improve the adhesiveness with the pressure-sensitive adhesive to use glass. It is possible to provide a transparent decorative material that is equivalent or better in terms of effects while solving the disadvantages.

Through the present invention it is possible to extend the product of the decorative transparent panel using the conventional glass to a product using a transparent plastic material. Therefore, it is possible to overcome the problems in weight, safety and transport storage, which were the problems of existing glass products, and can also be applied to outdoor advertising products.

Transparent decoration material of the present invention for achieving the above object is characterized in that consisting of a plastic layer and a design film layer that has undergone a pretreatment process.

Method for producing a transparent decorative material for achieving another object of the present invention comprises the steps of pre-treating the plastic substrate; And attaching a design film layer to the pretreated plastic substrate.

Hereinafter, the present invention will be described in more detail.

Plastic transparent decorative material according to the present invention is composed of a pre-treated transparent plastic layer and a design film layer engraved with various patterns.

The plastic is preferably a relatively thick thickness to replace the existing glass substrate, and should have a thickness of about 3 mm or more, but is preferable for replacing glass.

Specific examples of the plastic include a polycarbonate or an acrylic polymer, and are preferably transparent for the attachment of a design film layer including various patterns.

In addition, the plastic layer according to the present invention can suppress the heat loss of the plastic material, can improve the adhesion and adhesiveness with the adhesive used when the design film layer is attached, and other plasticizers and stabilizers generated when the plastic material is left for a long time It is characterized by the pre-processing of anti-migration to suppress the migration phenomenon that can cause heat loss due to additives.

Anti-migration treatment is largely divided into three types: 1) coating by in-line when plastic material is injected, 2) vacuum plasma treatment, and 3) atmospheric pressure plasma treatment.

First, in-line coating treatment is performed by using a treatment agent having a transition temperature higher than the glass transition temperature of the plastic substrate used. The composition of the coating treatment agent uses some additives having durability against discoloration such as acrylic treatment agent, curing agent and light resistance.

Second, the vacuum plasma treatment is a preliminary treatment step for modification through surface pitting. After forming a vacuum through a reduced pressure in a bulk state, surface treatment is performed on the plastic substrate through power generated from the generator.

Third, the atmospheric pressure plasma treatment is carried out after removing the vacuum state in the second plasma treatment, and manufactures the surface-modified plastic in a free state in a special environment and speed such as the vacuum state.

As described above, the design film layer having various patterns is attached to the anti-migration pretreated plastic layer. At this time, the pressure-sensitive adhesive may be used, and the type of pressure-sensitive adhesive used is not particularly limited, and the pressure-sensitive adhesive is not particularly limited as long as the design film layer can be adhered well.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, the present invention is not limited to the following Examples.

≪ Example 1 >

 Using a polycarbonate substrate (thickness 10 mm) treated with anti-migration in the In-Line coating process, a design film layer was attached using an acrylic adhesive to obtain a transparent decorative material.

<Example 2>

A transparent decorative material was obtained in the same manner as in Example 1, except that a polycarbonate substrate treated with anti-migration using a vacuum plasma was used.

<Example 3>

A transparent decorative material was obtained in the same manner as in Example 1, except that an anti-migration polycarbonate substrate was used using an atmospheric plasma.

&Lt; Comparative Example 1 &

A transparent decorative material was obtained in the same manner as in Example 1, except that the polycarbonate substrate without the anti-migration was used.

&Lt; Comparative Example 2 &

A transparent decorative material was obtained in the same manner as in Example 1, except that the glass substrate used in the prior art was used.

Experimental Example

When manufacturing the transparent decorative material according to the above Examples and Comparative Examples, it was determined whether the peeling when forming the design film layer on each plastic and glass substrate as an appearance, but the transparent decoration having excellent appearance surface state without peeling the design film layer The material was obtained.

From these results, it was confirmed that even in the case of replacing the conventional plastic instead of glass as in the present invention, it is not only attached with excellent adhesion when forming the design film layer through the anti-migration treatment, but also excellent in the appearance surface of the final decorative transparent decorative material .
