に到達した。That is, a feature of the method for producing an artificial marble plate of the present invention is that the packing material 3 having rubber elasticity and the metal mirror-finished plate 1 are used when the artificial marble compound is heated and compression molded. The metal mirror plate 1 is extremely inexpensive as compared with the conventional mold,
It has been found that an artificial marble plate having a different thickness can be easily manufactured by replacing the packing material 3 and has reached the present invention.

形しない程度であればよい。The present invention will be specifically described below with reference to the drawings. The metal mirror surface plate 1 used in the present invention is generally a stainless plate, a brass plate, a soft iron plate, a high-tensile plate, a stainless steel plate, etc., the surface of which is mirror-finished by chrome-plating the surface. It does not matter as long as it is processed. For example, if a specular plate having a satin or embossed pattern on the surface is used, it is possible to manufacture an artificial marble plate having an uneven pattern on the surface. Usually, two such mirror surface plates 1 are used, and the artificial marble compound is sandwiched between the two mirror surface plates for heat compression molding. Further, in order to prevent the packing material 3 from being deformed during the heat compression molding and the artificial marble compound inside from leaking out, the groove 2 is usually formed on each side near the side end of the lower metal mirror-finished plate 1. It is preferable that the packing material 3 is formed so that the packing material 3 is embedded therein. The width and depth of the groove 2 are not particularly limited as long as the packing material 3 mounted in the groove 2 is not deformed in the lateral direction by being released by the pressure during molding.

Rubbers exemplified by acryl, EPT and the like can be used without particular limitation, and these rubbers may be compounded with other materials such as metal as long as the rubber elasticity is maintained. This packing material 3 has excellent pressure resistance, heat resistance, tensile strength, solvent resistance, aging resistance, mold release and other mechanical and chemical strength because it is used for molding under heating and pressure. It is preferable that EPT rubber be the most satisfying one of the requirements.

It is preferably 0 degrees or more and 100 degrees or less. If it is less than 40 degrees, the mechanical strength is insufficient and it is easily broken by pressure. If it exceeds 100 degrees, the repulsive force against the press pressure is strong and the compound expands thermally and shrinks as the chemical reaction progresses. However, it is not preferable because it cannot be formed into a desired thickness. Further, when the hard packing material 3 is used, there is a problem that the compound is uniform and sufficient pressure is not applied during molding, so that the surface of the artificial marble plate is whitened. The thickness of the packing material 3 is preferably slightly thicker than the desired thickness of the artificial marble plate. When the groove 2 is provided on the metal mirror plate 1, the thickness of the packing material 3 is desired from the surface of the metal mirror plate 1. It is necessary to make the thickness so that it projects more than the thickness of the artificial marble plate. Also, the shape of the packing material 3 is not particularly limited, but it is particularly preferable to make the sectional shape T-shaped so that the width of the portion projecting from the groove 2 is wide because the artificial marble compound can be prevented from entering the groove 2. .

It is preferable to install a filter 5 made of a material that allows a certain gas to pass through but does not allow an artificial marble compound to pass through. When the degassing gap 4 is formed at a site other than the corners, the pressure during molding may cause the filter 5 to come off and the artificial marble compound to leak, which is not preferable. A suitable material for the filter 5 is a porous material, and examples thereof include felt manufactured from nylon fiber, polyester fiber, wool, rayon and the like. The thickness of the filter 5 is preferably 1.5 to 2.5 times the thickness of the molding plate, and the density is 0.2 to 0.5 g / c.
Those of m 3 are preferred. The shape of the filter 5 is preferably triangular.

ができる。An example of the method for producing an artificial marble plate of the present invention will be described below in sequence. First, a metal mirror plate 1 having a packing material 3 mounted near the side end is prepared, and a predetermined amount of artificial marble compound is placed thereon. The amount of the artificial marble compound used is most preferably approximately the same as the weight of the target artificial marble plate. Then, it is inserted into a press machine having another metal mirror plate 1 attached to the upper surface, or is covered with another metal mirror plate 1 from above and inserted into the press machine. After that, the artificial marble compound is cured by pressing at a predetermined temperature and a predetermined time for a predetermined time. After that, the artificial marble plate of the present invention is obtained by taking it out from the metal mirror plate 1. When the artificial marble compound is granular or pasty, it is preferable to place it on the central portion of the metal mirror plate 1. By doing so, the artificial marble compound can be uniformly spread from the central portion by the pressure at the time of pressing and can be filled in every corner, so that an artificial marble plate that is uniform and has no defective filling can be manufactured.

As a result, an artificial marble plate having a smooth surface and no whitening can be produced. If the groove 2 is formed at the side end of the metal mirror plate 1 and the packing material 3 is installed so as to be embedded, leakage of the artificial marble compound and lateral deformation of the packing material 3 can be prevented during heating and compression. Further, a gap 4 for degassing is provided at a corner formed by the packing materials 3, and a filter 5 is attached to the gap 4 to prevent leakage of the artificial marble compound and to efficiently discharge the internal gas. Since it can be discharged, it is possible to easily manufacture an artificial marble plate with a beautiful surface that does not entrap air.

A degassing gap having a width of 1 mm was provided at the four corners to be formed, and a polyester fiber felt having a thickness of 6 mm and a density of 0.3 g / cm 3 was attached to the gap. Then, a granular acrylic artificial marble compound was placed on the center of the metal mirror surface plate and heated and compressed for 15 minutes under the conditions of a hot plate temperature of 110 ° C and a molding pressure of 70 kg / cm 2 to a thickness of 3 mm and a length. A plate-shaped artificial marble plate having a width of 1880 mm and a width of 970 mm was obtained. The charge ratio of the artificial marble compound is 1 of the projected area of the forming plate.
It was set to 2%. The obtained artificial marble plate had no defects such as burrs after molding and whitening on the surface.
