The present invention relates to a method for manufacturing a synthetic resin sheet for high gloss, the production of high-gloss synthetic resin sheet by UV high brightness coating on the existing low pressure mela-mine impregnated paper (HPM) sheet or high pressure melamine sheet (HPM) sheet The present invention relates to a method for producing a synthetic resin sheet for high glossiness to have an effect of increasing production, reducing costs, and improving reliability of quality.

In general, a low pressure mela-mine impregnated paper (LPM) or HPM (high pressure melamine sheet) is used for manufacturing a plate material for use in wooden furniture, such as general furniture, tables, musical instruments, or floorboards for durability. ) After the sheet is put on, it is pressed and processed.

In general, the plate-like material manufacturing process using the LPM sheet is carried out through a series of processes of first impregnating the raw paper in urea resin, drying it, coating it with melamine resin, drying it again, and then cooling and cutting it. When using HPM sheet, paper or fibrous base material with natural and artificial patterns printed on one side is impregnated and laminated with thermosetting resin melamine and phenol resin, and over 50kgf / cm² in multi daylight press. The board | substrate material formed by compression molding by a thermal pressure can be obtained.

However, when UV coating is performed on the surface layer of the plate material manufactured by such a known manufacturing method, the coating process such as undercoat, midway, and topcoat is required. It is well known that the situation is emerging as a continuous solution in the industry.

In order to solve this problem, in the case of the conventional LPM synthetic resin production to adhere to the surface of the plate material for durability, formalin (61.6wt%), melamine (33.3wt%), distilled water (3.8%) in the reactor at room temperature After the addition of TEA (1.3wt%) into the reaction catalyst, the pH was adjusted to 8.3 to 8.5 and heated to 95 ℃, the reaction proceeds to reach 95 ℃ and 25 ℃ in the mass cylinder after 3 to 4 hours The mixture of distilled water and LPM resin (Low Press Melamine resin) in 4: 1 mixture when the cloudy occurs to cool to room temperature. When the temperature reaches 70 ° C during cooling, urea (12 wt%) and TEA (2.5 wt%) are added, DEG (diethylene glycol) (2.4 wt%) and methanol (3.0 wt%) are added at room temperature and sodium hydroxide is added. (0.8-1.9 wt%) to pH 9.0-9.2 to complete. The LPM resin (Low Press Melamine resin) prepared as described above is impregnated with a base paper after mixing 03 to 0.5 wt% of a curing agent, 0.4 to 0.8% of a releasing agent, and 0.5 to 1.0 wt% of a dispersant.

When the plate material is obtained by using the impregnated paper of the conventional LPM resin (Low Press Melamine resin), the adhesion to the plate material is good due to the characteristics of the LPM resin, but it is difficult to further coat the upper surface of the LPM sheet, thus coating UV coating. It is pointed out that a problem is that a complicated process of inducing adhesion by sequentially processing undercoat, midway, and topcoat work on most surface layers or veneers has been pointed out.

In addition, in processing the surface of the LPM paper (sheet), not only can not be painted with a paint or paint for wood, but also contains a problem that a lot of defective rate occurs because the coating is not 100%.

On the other hand, in the out-lay and In-Lay painting work, which is the pasting work of solid wood or veneer, the veneer uses various objects using a method of weaving while maximizing natural saving. In the case of the mosaic method, the cost of the mosaic is increased due to the limitation and loss ratio of various color expressions, it is difficult to supply the same material, and there is a problem of purchasing expensive equipment (laser). In addition, some of the conventional LPM sheet used to replace the veneer, but when produced by the inlay and inlay method, there is a problem due to the poor adhesion due to the adhesion of the sheet and the sheet and unstable surface coating after sheet molding.

Further, in addition to obtaining a plate material by using a synthetic resin sheet made of LPM resin, it is possible to obtain a plate material by using an HPM resin, which requires a separate adhesive treatment process due to the characteristics of the HPM resin, In addition, it is difficult to overcome the instability of the surface coating, as well as complicated in the manufacturing process, such as the addition of the surface coating process by the top coat.

Therefore, it is well known that a sheet having a high gloss surface and having a high scratch resistance is quite difficult, and many trials and errors have been made in the current industry even in its attempt.

On the other hand, unlike the methods described above, one of the methods for imparting high glossy and colorful aesthetics to the surface of furniture, polished materials such as pearl, metallic, hologram, or polyester film There is a method of directly attaching a paper containing an adhesive with an adhesive and coating the polyester resin thereon or a method of spraying the powdered varnish directly to the polyester paint paint.

However, this method has a problem that the resin layer is easily peeled off from the surface of the plate material by the gloss material having a particle form, or the surface is damaged even by a small scratch. In the latter, the effect of the gloss material is a colored paint. As a result of dilution, the problem of mixing a large amount of varnish has been raised, and in such a case, the color of the paint is discolored, and the problem of cost increase due to the use of a large amount of varnish is pointed out. There is a problem that the overall work process such as to be formed is complicated.

Therefore, in each of the high gloss application methods to the plate surface layer described above, the problem of peeling off when using LPM sheet or HPM sheet and the like, and the color fading and complexity of the process when using powdered varnish directly on the plate surface The problems of each method have been derived, and there are many difficulties in manufacturing a synthetic resin sheet having a high gloss (aka Hi glossy) and a plate material using the same while using an LPM sheet and an HPM sheet.

In order to solve such a problem, the present inventors provide a synthetic resin sheet through a manufacturing method according to "Korean multi-functional synthetic resin sheet manufacturing method and multi-functional synthetic resin sheet" No. 2005-128954, but expects a satisfactory high gloss effect There is a difficult problem to do.

Accordingly, the inventors of the present invention have devised the present invention in consideration of the various problems described above, by applying a UV (Ultra Violet-ultraviolet ray blocking) coating to an existing low pressure mela-mine impregnated paper (LPM) sheet or HPM sheet. It is possible to manufacture high gloss LPM sheet or high gloss HPM sheet with high gloss, which is produced without complicated painting process such as high, medium, and high, by manufacturing high gloss synthetic resin sheet for UV high gloss coating. The purpose is.

In addition, the present invention, when obtaining a plate-like material using the high-gloss LPM sheet and HPM sheet, preventing the peeling phenomenon between the plate-like material and the synthetic resin sheet, such as each high-gloss LPM and HPM, and durability, water resistance of the surface layer of the synthetic resin sheet It is an object of the present invention to provide a method of manufacturing a synthetic resin sheet for high glossiness to improve, increase adhesion to a plate material, high gloss effect, and improve productivity, reduce cost, and improve reliability of product quality.
