Description

UV Curing High Elongation and High Functional Coating Liquid Composition and Functional Film Using the Same {COATING COMPOSITION AND FUNCTIONAL FILM USING THE SAME}

The present invention relates to a high elongation and high functional coating liquid composition in which a coating layer is applied to a substrate constituting a decorative film for furniture molding, and a functional film using the same. Including a coating layer to be coated, solvents such as laccasin, ethanol, benzene, etc. used in furniture processing and manufacturing by providing high functionality such as high temperature elongation, solvent resistance, chemical resistance, fouling resistance, wear resistance, high gloss, yellowing resistance The present invention relates to a high elongation and high functional coating liquid composition which improves chemical resistance to, resistance to household chemicals, contamination resistance and surface hardness by food materials and writing instruments used in cooking, and a functional film using the same.

Apply the adhesive between the adherend and the decorative material using PET film coated with thermosetting resin according to the color and gloss of the surface of decorative materials such as wood products or furniture, and then apply spray coating or molding on the side. The process of decorating the furniture material is adopted.

However, there is a risk that harmful substances are released into the air during the manufacturing process due to the volatile organic compounds used to increase the wettability of the paint in the case of spray painting for the front and back side decoration during wood processing. The approach has the difficulty of incurring additional processes for processing the product.

In order to solve such environmental and manufacturing process problems, recent research and development have been carried out to solve the above-described problems through vacuum forming and pressure forming using a 3D decor sheet.

In many cases, indoors are located indoors according to the spatial layout characteristics of furniture. If ventilation is not performed smoothly, volatile organic compounds are continuously generated indoors, and there is a high risk of harmful substances accumulating in the air. In addition, thermosetting resins have a problem that yellowing continuously occurs with time, and due to the characteristics of the thermosetting process, the time required for production is longer than that of UV curing resins, and the investment cost of the initial production facility is higher than that of UV curing. The disadvantage is that a large production space is required.

Therefore, the present invention has been made to solve the above problems,
