Description

[Detailed description of the invention] The present invention relates to a method for manufacturing artificial marble.

Conventional artificial large buried stones use a mixture of marble stone powder and synthetic resin as a material, and in order to give this marble-like pattern, several types of coloring agents are arranged on the above-mentioned material to create different colors. The method used was to stir the colorant pigments to the extent that they would not mix colors to reveal a certain type of 4-color mixture, which was then poured into glue and molded.

However, when placed in natural marble, the molded products obtained by this method are inferior in texture and color, and it is difficult to obtain the natural shape, peaks, and beauty of natural marble. : It was difficult.

The present invention has been made in view of these points, and the white spots have a flow pattern on the surface similar to natural marble, are extremely hard and rich in ff0t heat, and are It is an object of the present invention to provide a method for manufacturing artificial marble that can easily form even a coarsely uneven shape and a large three-dimensional molded product.

The implementation of the present invention will be explained below based on the drawings.

Fig. 1 shows a clearing when manufacturing a 77-piece sink.In the present invention, first, the inner surface of the mold consisting of the lower mold 1 and the old mold 2 is covered with a sock, and polyvinyl alcohol, etc. Apply 1 lil # type agent 3 according to the following.

This is to make the light d< on the surface of the molded product sufficiently good, and also to make it easier to form the molded product into a “ne” shape.

Next, this separation 1. v, add 1 layer of ``Ton 4'' to the old type 1 side that was processed with punishment 6. This (old 1fA:, 1 Muruji 4 is a crowded customer fee different. 1 Kiki and turtle are two different kare, 1 life 9 Matsu' @ 4a and 4b.

Each viscous substance 4a, 4b is made of powder made of calcite,
Thermosetting resin, lined with polyester wood 11 and hardened AU

b is mixed with white hardness.

Therefore, the viscous proboscis 4a and 4b, which have different colors,
Mix in one container and mix to the extent that the colors do not mix with each other (so that the colors remain independent) to form a swirly kneaded pattern.

This is then cast into the mold described above, and then subjected to four motions using a pie breaker. Here, giving 7J+ ribs to the withering material 4 during molding removes air bubbles existing in the viscous material 4 and makes the surface smooth, and also makes the powdery material in the viscous material R4 smooth. The calcite sinks to the surface, the upper surface of the Zunawara mold 1, due to its own weight, increasing the surface hardness. Matashin@disperses Baku-sama's :1 favor to the history (I lose part).

After the mold is pressed in this way, the mold is released after the molded product inside has hardened.

The present invention is for manufacturing human remains dog stone with the above-mentioned configuration, in which two or more viscous "substances" of different colors are prepared in advance, and kP is not a mixture of elementary colors.

Turn this into a mold with +nTh and give it a vibration to make an e-fine (
Since it is made from a dense dotted area, it is possible to obtain a molded product with an appearance that closely resembles natural marble without mixing different colors.

Also, at the same time, calcite comes out on the surface of the molded product due to rk #J, so ++! The heat resistance after tN precipitation is also poor.
