preparation example Construction

[0016] The preparation method of artificial stone according to an embodiment of the present invention includes the following steps: (a) mixing two or more fragments with different particle sizes in the artificial stone raw material; (b) putting the artificial stone raw material mixed with the fragments into The step of mold; and (c) under normal pressure, using a vibrating device, with a vibration frequency of 1800rpm to 7000rpm, applying vibration for 10 seconds to 1 minute for the first time, so that the raw materials are evenly dispersed in the mold.

[0017] And, the preparation method of artificial stone also includes the following steps: (d) in order to remove the air bubbles of the raw material, under the vacuum condition of 30mmHg or more, apply a vacuum for 10 seconds to 30 seconds; and (e) under normal pressure, Using a vibrating device, at a vibration frequency of 1800rpm to 7000rpm, applying vibration for a second time for 30 seconds to 5 minutes to shape the artifi...

Embodiment

[0044] Cement-like artificial stones were prepared using natural stone fragments.

[0045] First, cement slurry as a binder of the artificial stone is put into a mold. At this time, the cement slurry used contains about 150 parts by weight of natural stone chips of about 5 mm in size, about 100 parts by weight of natural stone chips of about 2 mm in size, and about 50 parts by weight of cement for 100 parts by weight of cement. natural stone powder, about 30 parts by weight of water and about 2 parts by weight of plasticizer.

[0046] After putting the cement slurry into the mold, use the vibrating device to apply vibration for about 15 seconds for the first time to spread the cement slurry with a specified thickness. After the mold is put into the vacuum chamber and apply a vacuum for about 25 seconds to remove the inside of the slurry bubbles. After that, re-use the vibrating device to apply vibration to the mold for the second time for about 3 minutes, so that the natural...

Abstract

The present invention relates to a method and device for manufacturing artificial stone. More specifically, the method includes the steps of: (a) mixing two or more kinds of chips having different grain sizes with a raw material for artificial stone; (b) injecting the raw material for artificial stone mixed with the chips into a mold; (c) applying primary vibration using a vibration device such that the raw material is uniformly dispersed in the mold; (d) applying vacuum to eliminate bubbles in the raw material; and (e) molding artificial stone by applying a secondary vibration using the vibration device. According to the method and device for manufacturing artificial stone of the present invention, the deposition rate of chips exposed at a surface of artificial stone is maximized, and thus the external appearance of artificial stone can be more naturally expressed and resistance against abrasion and staining can be improved.

Description

technical field [0001] The present invention relates to a method and a device for preparing artificial stone, and more particularly, to realizing a more natural appearance design of artificial stone by maximizing the occurrence rate of fragments exposed on the surface of artificial stone, and improving wear resistance and durability. A method and device for preparing polluting artificial stone. Background technique [0002] In general, it is produced by mixing various natural stone fragments in a cement base using artificial stone, which is an exterior or interior material for construction, and then producing it through an extrusion process or a simple vibration process. [0003] However, the artificial stone prepared by the above-mentioned method has a technical limitation that the physical properties (strength) of the finished product are weak because the internal air bubbles cannot be sufficiently removed. Contents of the invention [0004] technical problem [0005] ...
