Description

  The present invention relates to a woodgrain patterned building material, a woodgrain carbon fiber composite material constituting the molded building material, and a method for producing the same.

  Conventionally, in the field of artificial makeup materials (building materials), efforts have been made to bring the texture of makeup materials made of natural materials made by traditional manufacturing methods closer. For example, with regard to a wooden board, there are many attempts to express the depression of the conduit portion of the wood by printing, and efforts are made to express various glossiness and unevenness of the surface based on the internal structure of the wood (for example, Patent Document 1 Paragraphs 0002 and 0003).

  On the other hand, it has been pointed out that when a grain is applied by direct printing on the surface of a building material or by pasting a printed decorative sheet, the three-dimensional effect is poor and flat (for example, paragraph 0005 of Patent Document 2).

  As described above, in the field of artificial cosmetic materials (building materials), building materials in which a three-dimensional wood grain pattern is formed are desired.

  Accordingly, it is an object to provide a molded building material that has a three-dimensional texture with unevenness and also has a superior performance not found in conventional building materials, and a thin carbon fiber composite material that constitutes the molded building material. .

  It was also an object to provide a manufacturing method suitable for a molded building material and a thin carbon fiber composite material constituting the molded building material.

  In order to solve the above-described problems, the present invention provides a base material having a predetermined thickness, and a predetermined carbon fiber composite thin body on which a three-dimensional wood grain pattern that is thinner and uneven than the base material is formed. And a molded building material in which the carbon fiber composite thin body is laminated and fixed (for example, adhered by an adhesive) to one surface side of the base material.

  Further, in order to solve the above-mentioned problems, the present invention has a step of applying an adhesive on the surface side of a substrate, and a carbon fiber composite thin body is laminated and placed on the application surface to 0.5 kg / square centimeter. And a step of crimping by applying a pressure of 1.0 kilogram / square centimeter, and a method for producing the above-described molded building material.

  Moreover, in order to solve the above-mentioned problem, the present invention has a step of sandwiching a carbon fiber composite material between an elastic body having a cushioning property and a wooden mold, and a subsequent heating and pressing step, Provides a method for producing a thin carbon fiber composite material in which a three-dimensional wood grain pattern is formed.

  The wood grain pattern building material of the present invention exhibits a performance derived from the properties of the thin carbon fiber composite material (scratch resistant, corrosion resistant, light weight, stickiness, strength, etc.) and has a three-dimensional wood grain pattern with irregularities. Because it is an excellent building material that also has the design characteristics, it can be used in various places including interior materials for buildings.

  Since the manufacturing method of the wood grain molded building material of the present invention is manufactured by a predetermined bonding step and a predetermined pressure bonding step, it is difficult for the carbon fiber composite thin body to be separated from the base material.

  The method for producing a wood grain pattern carbon fiber composite thin body of the present invention has the same unevenness as the unevenness appearing on one side of the wooden mold because it is manufactured by a predetermined sandwiching step and subsequent heating and pressing steps. A three-dimensional wood grain pattern can be formed on the carbon fiber composite thin body. Thereby, not only the visual effect of the grain pattern but also the tactile effect (hand touch, texture, etc.) can be obtained.

FIG. 1 is a perspective view showing a configuration of a wood grain molded building material. FIG. 2 is an explanatory view showing a method for producing a wood grain carbon fiber composite thin body. FIG. 3 is an explanatory view showing a method for producing a wood grain molded building material.

  Implemented as an interior material for buildings.

  First, the structure of the wood grain patterned building material will be described with reference to FIG.

  The wood grain pattern forming building material (1) is a predetermined carbon fiber composite thin body in which a base material (10) having a predetermined thickness and a three-dimensional wood grain pattern having a slight unevenness than the base material are formed. (20) and (FIG. 1).

  The carbon fiber composite thin body (20) is laminated on the surface side of the substrate (10) and fixed by adhesion.

  About the material of the said base material (10), although the timber (plywood) is used in a present Example, the general thing utilized as an interior material of a building can be selected.

  About the thickness of the said base material (10), although the 9-mm wood (plywood) is used in a present Example, the general thing utilized as an interior material of a building can be selected.

  The carbon fiber composite thin body (20) has at least a three-dimensional wood grain pattern (21) having slight irregularities formed on the surface by hot pressing (FIG. 2).

  Next, the manufacturing method of the said carbon fiber composite material thin body (20) or wood grain pattern molding building material (1) is demonstrated according to FIG.2 and FIG.3.

  A felt (32) having cushioning properties is laid on the lowermost base mold (31), and a release film (33), a carbon fiber composite thin body (20), and a release film are stacked thereon. Further, a wooden mold (34) is stacked thereon (FIG. 2).

  The wood mold (34) preferably has deep grain. For example, paulownia.

  A release film (33), a carbon fiber composite thin body (20), and a release film are further stacked on the wooden mold (34), and a felt (32) having cushioning properties is stacked thereon. (FIG. 2).

  The layers are stacked in the same manner and sandwiched between the uppermost base molds (31) (state shown in FIG. 2).

  FIG. 2 shows that four carbon fiber composite thin bodies (20) and three cushioning properties are provided between the lowermost base mold (31) and the uppermost base mold (31). This is an example in which a felt (32) having two wooden molds (34) and the like are sandwiched.

  The laminate sandwiched as described above is put into a vacuum hot press apparatus, and in a vacuum state, the heating temperature is set to 170 degrees and the pressure setting is set to 3 kilograms / square centimeter, and the vacuum hot press apparatus is operated.

  The operation time of the vacuum press apparatus was 3 hours.

  Ten minutes after the hot plate provided in the vacuum press apparatus exceeds 170 degrees, the vacuum pump is turned off and the outside air is introduced.

  90 minutes after the hot plate exceeds 170 degrees, the heating is stopped.

  Wait until the temperature of the hot plate reaches 40 ° C. or less, and take out the sandwiched one.

  The release film (33) on the felt side surface of the hardened carbon fiber composite material is peeled off.

  Further, a synthetic rubber adhesive (11) is applied to the surface side of the substrate (10) to a thickness of 0.5 to 1.5 mm, and the carbon fiber composite material (20) is laminated thereon. And press with a roller while applying a pressure of 0.5 kg / square centimeter to 1.0 kg / square centimeter (FIG. 3).

  Then, after drying and the said adhesive agent (11) hardened | cured, external shape formation is carried out and the peeling film (33) of the surface (wooden side) is peeled off, and a grain pattern formation building material is completed.

  The wood grain pattern molding building material of the present invention, the wood grain pattern carbon fiber composite thin body is an excellent molded building material that exhibits the performance derived from the properties of the carbon fiber composite thin body and also has the design by the predetermined wood grain pattern, Since it is a thin carbon fiber composite material, it has industrial applicability.
