Abstract

PURPOSE:To manufacture efficiently a decorative material superior in design, by a method wherein a fluid and nonfluid patterning materials are fed within a frame and the patterning materials are molded by heating them with a high- frequency and heating devices. CONSTITUTION:A fluid patterning material 3 of a powdery and granular body and a nonfluid patterning material 4 of a cylindrical or lumpy matter such as pasty or dry blended polyvinyl chloride are fed within a vessel formed of a frame 1 and bottom plate 2. The patterning materials 3, 4 are pressed with a press plate 5 and high-frequency wave W1 is generated by a high-frequency generator 6 through a metallic plate 7. With the high-frequency wave W1, the center part of the patterning material in the vessel is heated and at the same time heated like W2 by a heating device 8 such as Nichrome wire in the metallic plate 7 and a similar heating device 10 in a base body 9. Then at the same time, heating is performed like W3 with the frame heated by the whole of the device.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a decorative material suitable for an interior material with excellent design.

(Prior art and problems) There is a conventional method for manufacturing thick sheets using a hot press machine, but when trying to obtain a thick lump using a fluid raw material, it is difficult to heat and harden it deep down. It took a long time to clean, and there was a risk of discoloration in areas near the heat source.

In addition, a method using high frequency is disclosed in Japanese Patent Application Laid-Open No. 62-15271.
As disclosed in Publication No. 0, the comparative +19 thin sheet is used to mold an uneven pattern, but if only high-frequency heating is used to mold a thick lump, conversely, only the center part It also had the disadvantage that it was heated too quickly, causing discoloration in the center when the periphery became gelled.

In addition, the method described in the above-mentioned publication could only obtain a simple printed pattern, and could not provide a deep stylistic feel.

(Means for Solving the Problems) The present invention provides a method for manufacturing decorative materials with a higher design quality, in which a fluid pattern material and a non-flow pattern material are supplied into a mold with a certain depth, and a high frequency The gist of this method is to provide a method for producing a decorative material, which is characterized in that the patterned material is heated by a heating means other than high frequency at the same time as the patterned material is heated and shaped, and then slit in the thickness direction. The present invention will be explained below based on the drawings.

FIG. 1 is a manufacturing process diagram of the present invention, and numeral 1 indicates a highly insulating mold made of stone, glass, or the like.

Formwork 1 has a side of 10 to 200 cm and a depth of 2 to 20 cm.
m is desirable.

A container is formed by this formwork and a bottom plate 2 such as an aluminum plate, and inside this container, a fluid pattern material 3 in the form of polyvinyl chloride (PVC) paste or granular material such as Tribrane I and columnar or lump-shaped materials are formed. A non-flowable pattern material 4 of the object is supplied.

A press plate 5 is provided above the container to press the pattern material 3 and the pattern tips 4, and a high frequency wave generator 6 generates a high frequency wave W1 via a metal plate 7.

The central part of the pattern material in the container is heated by high frequency, and at the same time, it is heated as shown in W2 by non-high frequency heating means 8 such as nichrome wire in the metal plate 7 and similar non-high frequency heating means 10 in the base 9. At the same time, the mold is heated as shown in W3 by the mold that is heated by the entire apparatus.

In this way, the central part is heated by Wl, and at the same time the peripheral part is heated by W2 and W3, and the synthetic resin patterned stone is rapidly gelled.

The lump obtained by the above method is carried out through the entrance/exit 11.

7. The device is covered with a housing 12 having electromagnetic shielding performance.

Examples of the above-mentioned apparatus for producing decorative materials using high frequency waves include RH7, RH15, and RH50 manufactured by Sansui Vinita Co., Ltd.

FIG. 2 is a plan view of the decorative material of the present invention. The decorative material of the present invention is obtained by slitting the obtained lump in the cutting direction into 1-5 mm pieces.

Reference numeral 13 indicates the cut point of the patterned part made of the non-flowable pattern material of the above-mentioned lumps or columns (hereinafter referred to as the non-flowable pattern part), and 14 indicates the point where a uniform pattern is always obtained, and the part where the pattern of the lumps is aggregated. In this case, it is possible to obtain a pattern with a wide variety of colors and shapes.

Further, the fluid pattern portions 1/1 are always filled between the non-fluid pattern portions 13 and firmly adhere the pattern portions 13 to each other.

The L pattern part is integrated and quickly heated to gel, so the pattern does not change color and a beautiful makeup iodine can be obtained.

The obtained decorative material is laminated on a base such as a PvC sheet and can be applied to interior materials such as flooring and wall coverings.

By combining high frequency and non-high frequency heating means, the pattern material is quickly heated and gelled.

(Effects of the Invention) ■ High design quality could be obtained by arbitrary silk combination of a fluid pattern element and a non-fluid pattern material.

■Heat gelation was rapid and the sowing time was short, making it possible to efficiently obtain a decorative material without thermal discoloration or deterioration of the material.

(2) Even though a thick lump was formed, the +a material was heated uniformly and was in a good gelling state.
