Abstract

PURPOSE: A natural pattern wood floor sheet, and a method and an apparatus for manufacturing it are provided to make the floor sheet seen like real wooden floor by arranging sheet pieces into a wooden floor, and to improve the heat resistance property thereof. CONSTITUTION: The natural pattern wood floor sheet(1) consists of a synthetic rubber sheet substrate(1), a natural pattern wood(3) attached to the surface of the sheet substrate with an adhesive layer(2); and a transparent protective coating layer(4) formed on the surface of the natural pattern wood. For assembling the floor sheet like a wooded floor, the floor sheet is compressively dried at a temperature of 80-90deg.C and a pressure of 100-200kg for 1-2minutes after the natural pattern wood is attached thereto, then the surface of the natural pattern wood is smoothly ground and coated with the transparent protective paint, and finally heated with an infrared heater.

Description

Natural veneer sheet and its manufacturing method and apparatus

The present invention is to propose a veneer sheet and a manufacturing method and apparatus thereof.

In the prior art, Japanese Laid-Open Patent Publication No. Hei 7-42350, a floorboard according to the chuck tube method is provided with a plasterboard floorboard having a size of 1 × 6 × 12 mm (thickness). Such a plasterboard is a decorative layer (printed paper or natural veneer) attached to the surface of the plywood, the substrate using a wood fiber board, wood cutting board in addition to the wood plywood or by attaching a heavy fiber board with a thickness of 3-5mm to the plywood board It was also used as.

However, a floorboard having a decorative layer attached to one side of a plywood cannot be substituted as a sheetboard sheet. In other words, the floor covering is attached to the floor or spread on the floor to form the floor of the floor using only thin paper or synthetic resin sheet adapted to the floor. However, the floorboard is to assemble the plate on the floor frame to make the floor to the floor, the floorboard is the flooring to maintain the strength and thickness to support all the loads loaded indoors.

On the other hand, the conventional wood veneer sheet is a direct printing of the wood grain pattern on the flexible synthetic resin sheet, the quality of the pattern does not reach the natural wood grain pattern, and the texture is easily demonstrated, unlike the wood, and attaching the natural veneer to the flexible sheet Natural veneers were very difficult to break because of the nature.

Therefore, in the past, in order to obtain a complete wood grain pattern on the flexible sheet sheet, it was necessary to construct the floorboard eventually.

The present invention is made of a sheet of synthetic resin sheet for ordinary floorboards, but by attaching the natural wood veneer to the surface of the flexible resin sheet substrate that is cut so that it can be assembled like floorboards, the construction method is a floor covering sheet sheet It is an object of the present invention to provide a floor sheet material that can be installed as a floorboard sheet of a warm ondol room by using an adhesive layer arranged in a floorboard shape so that it can look like a parquet, and the property of the sheet material maintains heat resistance.

1 is an enlarged cross-sectional view of the sheet of this invention.

Fig. 2 (a), Fig. 2 (b), Fig. 2 (c), Fig. 2 (d) and Fig. 2 (e) are the manufacturing process diagrams of the burying sheet of the present invention.

* Explanation of symbols for main parts of the drawings

1: sheet base material 2: adhesive layer

3: natural veneer 4: protective coating layer

This invention is demonstrated in detail according to an Example drawing.

The present invention is a heat-resistant and flexible synthetic rubber sheet base (1) as the basis of the sheet; Natural veneer 3 attached to the surface of the sheet base material by an adhesive layer 2; It consists of the veneer protective coating layer 4 apply | coated to the veneer surface.

The synthetic resin sheet base material, such as thickness and material flexibility, can use most of the base material of the conventional sheet material, but the foamed sheet material is difficult to use as the invention sheet base material can not protect the natural veneer. As the sheet base material used in the present invention, a PVC sheet sheet made of a conventional PVC and composed of a filler, an emulsifier, a nonflammable material, or the like is used. Natural veneer uses conventional natural veneer for furniture. As the adhesive, necessary adhesive force is generated between the synthetic resin sheet substrate and the natural veneer; Flexible sheet to have necessary durability as distribution sheet, construction process or sheet; In addition, a flexible adhesive such as a latex-based adhesive or a polymer-based adhesive, which has no toxicity, is used as the sheet. Since this invention transparent paint is apply | coated to the surface of a natural veneer, and penetrates a veneer, and arrives at an adhesive layer, it forms the transparent coating layer 4 which integrates and protects a veneer to a sheet | seat base material. The coating layer represents the texture of the wood veneer in the process of distribution, construction or use, and uses a transparent paint that protects the natural veneer. As an example of the coating material for coating layer composition, 60-70 weight part of unsaturated polyester resins, 20-30 weight part of monomers, 2-5 weight part of photoinitiators, 10-20 weight part of pigments, 2-4 weight part of preparations, and ketones Vent) 2-5 parts by weight of transparent paint Ubirak 100 (DY-2), 25-30 parts by weight of unsaturated polyester resin, 30-40 parts by weight of unsaturated acrylate resin, 20-30 parts by weight of monomers, ketones (Solvent) Transparent paint Ubirak 200 top coat (TY (P 0)) composed of 1-5 parts by weight, matting agent 5-10 parts by weight, preparations 2-4 parts by weight and photoinitiator 3-8 parts by weight do.

The manufacturing process of this invention is demonstrated according to Example apparatus 2, as follows.

In FIG. 2 (a), the adhesive 2 'is uniformly applied to the sheet of cardboard sheet base material 1 in the adhesive applying roll sets 13, 13', and 14. The sheet base material 1 is supplied horizontally on the bed 11, and the adhesive 12 is supplied from the application roll sets 13 and 13 'and uniformly applied to the upper surface of the substrate while passing between the rolls 13 and 14; After the adhesive is applied, it is placed on the conveyance belt 15 and cut into a predetermined length by the cutter 16.

2 (b) is a step of attaching the natural veneer (3). The sheet material 1 coated with adhesive material is transferred from the conveying belt 15 onto the bed 21, and several natural veneers prepared by adjusting the humidity on the sheet base material la coated with the adhesive material according to the method of pasting veneer in the furniture process. Attach it while cutting it with a knife and close it closely using a manual tool such as a sealer. Sheet base material with a veneer is carried on the conveying belt 25 and is conveyed to the pressing dryer.

2 (c) is a compression drying step. The sheets 1b, 1b and 1b of the transferred process were sandwiched between the laminated heating plates 32, 33, 34 and 35 at 80-90 ° C. on the bed 31 at a pressure of 100-200 kg (pressure for the total area). -2 minutes heating, pressurizing, attaching, drying and conveying to the next stage by conveying belt 36.

FIG. 2 (d) is a sanding step. After drying the sheet natural veneer surface on the transfer table 41, the sheet of the above process is smoothly and smoothly polished with the belt sand paper 42, and then the sanded sheet Id is transferred as the transfer belt 45. Transfer to.

FIG. 2 (e) and FIG. 2 (ea) are two steps of veneer protective coating process. On top of the conveying roll 51 and the conveying belt 51 ', the transparent protective paint 55 is applied to the natural veneer surface of the sheet 1d given in the above process by the applying rolls 52 and 52' and the infrared light 54 The baking film is baked by infrared heating by () to obtain the finished sheet sheet 1e with natural veneer.

The sheet of the invention thus obtained is provided with a surface layer made of natural veneer on the surface of the flexible synthetic resin sheet substrate, and the sheet substrate construction method is to be attached to the floor in a shape of parquet, and has heat resistance. It is to provide a high quality sheet sheet material that can form an ondol floor like a sheet sheet.
