Description

200300010 V. Description of the invention (1) ------- " The genus Kujutsug of the invention belongs to the decorative floor covering and its manufacturing method, and the special 2 is about the decorative melamine laminate The PVC floor covering is made by laminating a melamine board having excellent surface physical properties on a PVC board, and a manufacturing method thereof. In the prior art, floor coverings are usually used in commercial buildings, shiny stones or P ^ VC magnetic monuments and others as shown in Figure 1. For example, marble and granite stone items are also used to restore the most commonly used items such as department stores and commercial buildings in office buildings. Although these stone products have high durability, taking into account the high prices of these products necessitates the development of alternative products. PVC magnetic stele products have been developed into a two-tone marble pattern, making it similar to natural materials. These pVC tiles are crushed into various irregular shapes and then extruded or continuously extruded to produce PVC sheets of more than two types with marble effect as shown in Figure 2. However, its degree of naturalness is limited to the color and texture caused by excessive fillers fed during the manufacturing of pVC tiles. In order to improve this, the decorative pVC resin floor covering 'of Fig. 3 has been developed which has a printing layer covering a PVC board layer. Figure 3 shows a decorative floor covering, which is combined by extruding a cluster of layers including the following sequentially inserted layers: a matrix layer (1) that produces product thickness and adjusts product balance, and an artistic pattern on the matrix layer (1) a printing layer (2) showing a decorative effect f, a transparent layer (3) that protects the printing layer (2), a surface coating layer (4) that generates pollution resistance and scratch resistance to the product, and

To ignore. The method of J material includes the steps for manufacturing the above-mentioned traditional decorative floor coverings: 1 to make a thickness of 2 by using a light-stretchable or hard Pvc resin compound to a matrix layer of 3 mm (1); clothing ie the printing layer (?) and the transparent layer (3) on the base layer (1), and the balancing layer (5) under the substrate layer (1); in the printing method using gravure or transmission, the natural Stone, wood ^ pattern printing to the light, including improved hiding power, 0 to 20 weight I "The stretchability of titanium oxide or rigid pvc resin compound made from 0.08 to 0. 1 5 After the Mizhi PVC resin sheet, the dry brush layer (2) is used; 'The transparent layer is made of a transparent PVC resin film with a thickness of 〇 · 丨 〇 to 0.95mm by borrowing a light-stretching or rigid PVC resin compound ( 3); Use light-stretching or rigid PVC resin compounds to produce a balanced layer (5) with a thickness of 0.32 to 0.95 mm; place the printed layer (2) and transparent layer (3) manufactured above on the After the substrate layer (1) is applied, the printing layer (2), The bright layer (3) and the balancing layer (5) are laminated on the substrate layer (1), and the balancing layer (5) is inserted under the printing layer (2); and the thickness of the layer is 5 to 60 microns and includes an amine group. After the surface coating agent of the main component of propylene gallate is applied to the transparent layer (3), the ultraviolet (ultraviolet)

Description of the invention (3) Light) curing, or after the surface coating agent including the main component of urethane resin or acrylic resin is applied to the transparent layer (3), heat curing or ultraviolet curing is performed to produce Surface coating layer (4) to produce a decorative floor covering having a thickness of 2.5 to 5.0 mm. Although the traditional decorative floor coverings manufactured according to the methods described above are widely used due to their low cost and easy installation, the top layer of the surface covering is non-pollution-resistant or scratch-resistant, making the floor covering Easily worn. As a result, areas that are highly transported are contaminated and scratched, reducing their use in commercial buildings. Decorative floor coverings which have recently been introduced with a top layer of a melamine resin impregnated layer having high hardness have been found to solve these problems. Figures 4 and 5 show this conventional floor covering. Figure 4 shows a cross-sectional view of a laminate for decoration according to European Patent Application No. 0 561 086 A1. The decorative laminated board is sequentially placed on the P v C resin layer (1 1) including a phenol resin adhesive layer (丨 2), a melamine resin impregnated layer (1 3), and an melamine resin impregnated outer layer (丨 4). Fig. 5 shows a sectional view of a laminated material according to Japanese Laid-Open Patent No. Heisei 9-2 3 3 6 6. The laminated material is laminated on a rubber or a thermoplastic resin (31). The laminated material includes a hot-melt film (32), a pattern paper (33), and an outer layer (3 4) impregnated with a melamine resin. The decorative floor coverings using layers impregnated with traditional melamine resins not shown in Figures 4 and 5 can be protected by using, for example, the outer layer impregnated with melamine resin (14), the transparent protection of paper impregnated with melamine resin Layer (25), melamine resin impregnated outer layer (34) as melamine

Shuyue said that the top of the layer is to solve the problem of decorative floor coverings. However, this decorative floor covering has various problems, for example, the adhesive layer used to simultaneously adhere the melamine resin impregnated and the PVC resin has poor adhesive strength. Mask layer Furthermore, the decorative laminate of FIG. 4 has the following problems: the phenol resin of the phenol resin adhesive layer (1 2) has poor adhesion strength, which is due to the pvc resin of the resin adhesive layer τ s Layer (the poorer phase of the PVC resin) and when the decorative laminate is held by the edge of the decorative laminate, the same day: the center of the wound will collapse because it does not have a hard board to compensate for the melamine Vulnerability to external impact. In addition, the laminated material of Fig. 5 has the following dimensional stability problems. It includes a hot-melt film (3 2) itself used as a rubber or thermoplastic resin (31) and pattern paper (33). The shrinkage caused by the increase in crystallization of the hot-melt film (32) between the adhesive layers at the bonding temperature, and the difficulty in maintaining the balance when the laminated material changes according to the temperature and degree of roofing. Figures 1 to 5 show that Traditional decorative floor coverings also have problems with curling and 'bending', especially at temperatures lower than 丨 〇 and higher than 4 〇. This is caused by the substrate itself due to the different temperature and humidity levels of each constituent layer. Different income The low temperature change resistance caused by the shrinkage and expansion ratios must be supplemented by the structure of the base body.
