Abstract

PURPOSE: A method for forming various pattern on an artificial stone by using a screen is provided to form the pattern as a form of one mass on the paste used in the preparation of an artificial stone. CONSTITUTION: A method for forming various pattern on an artificial stone comprises the steps of applying some vibration to an aqueous binder paste containing water inside a molding frame so as to allow the paste(10) to be descended and the liquid(11) to be floated on the upper surface; locating a screen at the part higher by about 2 mm than the separated liquid of the paste upper surface, and sieving cement powder, gypsum powder, or stone powder as a binder main component so as to allow it to be put on the upper surface of the paste through the hole punched on the screen; instantaneously absorbing liquid for strong fixing, thereby forming the one mass of cement powder, gypsum powder, or stone powder and paste; and fixing the fixed one strongly.

Description

How to implement different patterns on artificial stone using screens {a imitation stone}

The present invention relates to a method for printing on a paste used in the manufacture of artificial stone, and in particular, to implement the pattern in the form of one aggregate on the paste using a screen.

As a method of realizing a pattern having a pattern specific to artificial stone, there is a method of mixing a binder and a color chip and pressing the mold at a predetermined temperature and a method of freely mixing pigments in the binder.

However, when molding by mixing the color chip with a binder, there is a disadvantage that it provides only a simple granite pattern form and is easily eaten by consumers due to monotony.

In addition, in the case of allowing the binder to be mixed freely with a pigment or the like, the shape after molding is merely to implement a cloud pattern.

Therefore, this pattern has a limit to meet the taste of the consumer's advanced taste, so the emergence of a new pattern was required in artificial stone.

Therefore, in order to meet these demands, the limited supply of natural marble must be replaced and the cost of supplying a considerable economic cost is incurred.

Therefore, in the present invention, by using a screen for printing the paste used in the manufacture of artificial stone to implement in the form of agglomerates in the paste to meet the advanced needs of consumers.

In addition, by utilizing the screen of the present invention to implement a pattern of artificial stone that can meet the needs of consumers to improve the competitiveness of the business and to implement the method of using the waste stone material for environmental protection.

To this end, the aqueous binder paste is vibrated, the paste is lowered, and the emulsion is floated, and then the screen is used on the upper surface of the binder while the cement or gypsum, which is the main component of the binder, is lowered and lowered through the perforated holes of the screen. It is to be attached to the upper surface of the paste to implement a variety of patterns by repeating this process, and to produce a pattern in one aggregate by sticking to excellent hygroscopicity to produce a single aggregate.

Therefore, various patterns are embodied in the form of one aggregate on the surface of artificial stone as the intention of the manufacturer, and these patterns are simply manufactured by forming the paste.

Hereinafter, the present invention will be described in detail with reference to the following examples.

First of all, an aqueous binder such as cement, gypsum, stone powder and paste of an emulsion used in the present invention utilizes a very easy to use screen.

First means

First, a slight vibration is applied to the aqueous binder paste containing appropriate water in the mold, so that the paste 10 is lowered and compacted, and the liquid (water or emulsion) 11 is floated to the upper surface.

In this way, when the lowered paste is laminated, a constant density is maintained.

Second means

The cement powder, which is the main component of the binder, is placed on the screen (perforated in a uniform pattern) 12 of 1 degree color about 2 mm above the liquid on the upper surface of the paste separated from the liquid (water or emulsion) by the first means. Alternatively, the plaster powder or stone powder 13 is lowered to a sieve (not shown) and manipulated so that the pattern powder 18 is seated on the upper surface of the face 10 through the hole 14 punched in the screen 12.

In such a state that the manipulated screen is fixed, cement powder, gypsum powder, or stone powder positioned on the upper surface of the screen is evenly discharged into the hole by using a spatula.

Third means

In the same manner as in the second means, screens of 2nd and 3rd colors (holes are drilled at different positions from the 1st screen) and colored cement, gypsum, and stone are sieved and arranged on the upper surface of the paste. .

At this time, the water or emulsion liquid present on the upper surface of the face allows the powder to be temporarily fixed by the surface tension as it falls through the hole drilled in the screen.

However, the powders fixed by the liquid have a high viscosity such that the distance between particles is too loose and difficult to manipulate so that they can be easily distracted.

Fourth means

The cement powder, the gypsum powder, or the stone powder placed on the upper layer of the paste by the third means is strongly adhered to form a lump with the paste, while maintaining its shape.

To this end, anhydrous gypsum, lime, lime powder, cement powder, silica gel, etc., which absorb a large amount of liquid (emulsion, etc.) instantaneously, are used. In the present invention, it is assumed that a material having a low price is lime powder.

In addition, when using lime powder, prepare a box equipped with a very fine semaphore (15) on the lower surface of the square box (16) so that the lime powder cannot escape, and the lime powder (17) inside the box at a constant height. It is filled.

After that, place the lime box on the top of the paste and press it evenly to keep the shape intact while strongly adhering to the powder that is not yet strongly adhered.

It is operated by applying pressure to the pattern powder. It uses the instantaneous absorption power and pressure of lime powder. It presses the pattern powder that is fixed (temporarily) in the wet state on the upper surface of the paste to become a paste and one aggregate, and to form a gel. In order to remove the viscosity of the pattern powder 18, the strong absorbing power of lime is used, and the lime powder is filled in a box so as to have a constant pressure so as to absorb moisture as well as to press and fix at the same time.

Therefore, by manufacturing as described above, it can play a role of greatly improving the productivity of the artificial stone industry with various pattern screens such as the form of mass prints, and releasing the design of artificial stone, which had already reached the limit of design decades ago, to the level of free creation. It's very groundbreaking.
