Preparation Example 2-10

To 100 parts by weight of natural wood fibers of beech treated in Preparation Example 1 above, ocher, elvan, and carbon fibers were put in paper containers as shown in Table 3, respectively, to form a paper stock. Then, paper mulberry natural fiber was made by using a paper machine in which JangMong, HwanMang, JangMang, which is composed of the structure as shown in FIG. The paper machine of FIG. 1 has three nets in which wetlands of paper are formed, and the paper machine can manufacture up to three layers of paper. In the case of 1-layer paper, the mixture of wood pulp and long fiber can be used to make the operating pattern on the surface, and the second-layer paper is made of long fiber in the long net (1), and the wood pulp and After the wetlands are made of functional materials, the two layers can be combined to form a long fiber-like operating pattern on the surface. The three-layered land is made of long fiber from Jangmang (1) and Jangmang (3), and the wetland is made of wood pulp and functional material from Hwangang (2). Can be. At this time, the paper mulberry natural fiber grassland was made of two-layer grass paper system of long-distance network, paper width of 1250mm and paper grass speed of 25m / min based on the basis weight of 60g / ㎡.

Combination was composed of one sheet.

② Physical property of impregnation

The resin reaction process is the most important process in the manufacturing process, and it is a process that synthesizes resinous material by stirring melamine, phenol, formaldehyde, plasticizer, and other additives at an appropriate temperature and time. Since defects occur over the resin properties, it is most important. Physical properties such as viscosity and solid content of the used resin were used under the conditions shown in Table 4.

③ impregnation and drying

In the resin impregnation process, the melamine resin transferred from the reaction process is introduced into the impregnation tank, and the process of immersing and removing the hanji-shaped paper in the resin in the impregnation tank is repeated to remove the air inside the paper and sufficiently infiltrate the resin to the inside of the paper. Next, a roller and a squeeze method were used to uniformly apply the resin on the surface of the sheet of paper in the form of a paper in good condition. The melamine resin impregnation amount is 53 to 60%, preferably 57%, and the phenol impregnation resin amount is 36 to 38%, preferably 37%. The drying process was carried out according to the two purposes of advancing the condensation of the resin to the extent of removing the solvent and the appropriate molding fluidity, and drying in a forced-air drying furnace to ensure the proper condensation of the resin. The drying temperature was dried at 115 ° C. for 3 minutes.

④ Lamination and Press

The lamination of Hanji surface paper and kraft paper containing functional materials was carried out in 15 multi-stage presses.The lamination method was a sheet of Hanji surface paper containing functional materials impregnated and dried in melamine resin and phenol. Three sheets of kraft paper impregnated with resin and dried were put together in a hot plate, a stainless plate was placed on the surface layer, heated and pressed by a press, and a functional paper-made melamine decorative plate was made. The molding process first put the composition paper → mirror surface coating → pressure holding (120 ~ 160 ℃) → pressure, high temperature molding (150 ~ 180 ℃) → 30 minutes maintenance → molding completed → mirror plate → peeling mirror surface → functional It was performed in order of Hanji Cosmetic prototype. Pressure and temperature conditions during molding are shown in <Table 5>.
