Description

Method of Practical use and Manufacture of Patterned Silk Screen and also Manufacture of Insulation Patterned Stone

The present invention provides a method of manufacturing insulation pattern stones and utilizing pattern screens, which will make a great contribution to the building materials market by taking an ideal form that satisfies insulation, flame retardancy, workability, and designability, which are the main performances of building exterior materials. will be. Furthermore, the present invention also provides a method of binding of the thin film ceramic coating agent additionally obtained in the process of the present invention, thereby imparting novel technical benefits to the related industry.

The prior art in the field to which the present invention belongs,

① Manufacture of artificial stone: Artificial stone widely used as building exterior materials is mainly made of cement. Cement is difficult to weave due to its characteristics and can be transported and loaded when the basic curing for at least one day, and it is a very low productivity industry to develop strength only after five days of curing in water. In terms of designability, there is no way other than the simple pattern realization method of coincidence obtained by painting and silica sand powder with a pigment for cement to simulate the stone pattern.

② Limitations of Ceramic Coatings: Ceramic coatings are coatings that can only be coated in micro units. Therefore, the ability to attach relatively large particles such as silica sand is not currently considered possible.

The present invention provides a ratio of 2: 8 of a strong aqueous acrylic bond and water, thereby appropriately reducing the bond strength of the bond to serve as a crosslinking agent, and maintains a uniform form of silica sand having no viscosity by stirring with silica sand. At the same time, it is possible to adjust the concentration to 20% so that the synthetic resin solution and the thin film ceramic can be easily penetrated and filled by having a sponge shape.

This is a new technology that greatly speeds up the complicated process and completion date of molded products using cement, and it has economical and workability that surpasses the resource waste and labor fatigue caused by the silica sand and water-bonding method of construction in the field. Technology.

In addition, the production and utilization method of the pattern screen using the OHP film, which is a pattern realization method provided by the present invention, is a new technology that provides a way to realize the reality of natural patterns with only particles such as stone powder, which does not pass through silk screen Instead, it is a principle that a beautiful pattern can be realized on a substrate by simply transferring a pattern to the OHP film using a computer graphic technology, perforating it according to the pattern, and passing more than 500 mesh fine silica sand. This gives more realism than the construction of the adhesive sheet, which is performed to enhance the design of the plaster, and the use of natural materials can not compare the strength and the design.

A new building material is produced through impregnation of 40% of a synthetic resin for hardness protection or impregnated with a ceramic coating agent on the silica or the silica sand combined with a heat-insulating plate of a sponge-type colored silica manufactured as described above.

① First step: Apply crosslinking agent and silica sand on top of panel.

② Second process: precisely stone pattern with 'pattern screen' and color silica sand

③ 3rd process: 80 ℃ / 60 minutes forced hardening in dry stove

④ 4th process: Impregnated in 40% of synthetic resin for thermosetting

⑤ 5th process: thermosetting at 80 ℃ / 30 minutes

The production method of the insulating pattern stone provided by the present invention consists of five processes as shown in Figure 1 above.

① First step: Apply crosslinking agent and silica sand on top of panel.

② Second process: precisely stone pattern with 'pattern screen' and color silica sand

③ 3rd process: 80 ℃ / 60 minutes forced hardening in dry stove

④ 4th process: Impregnated in 40% of synthetic resin for thermosetting

⑤ 5th process: It goes through about 5 processes such as heat curing at 80 ℃ / 30 minutes and the detailed method is as follows.

Primary process (stirring agent manufacture)

: Silica sand is placed in the mixer and 20% aqueous acrylic bond is poured into 30% of the volume of silica sand and stirred to make the material too unnecessary to increase the amount of bond. This material is placed in a square frame, or 2 mm thick on top of PVC foam panels or other plates to lightly level. Into the rectangular frame is for the production of building materials in the form of tiles excluding the thermal insulation performance, in the present invention is premised to combine with the insulation panel.

The evenly spreading stirrer does not have a specific pattern and should be given a beautiful pattern. The present invention proposes a method that can implement the pattern of granite or high-quality marble in large quantities.

Second process (screen production and pattern formation)

: Pattern screen should be manufactured to build beautiful and diverse pattern of stone and mass printing system of the pattern. The material used for the screen is a 0HP printing film that can substitute for silk screen. When the image of the stone pattern is printed on the OHP film using computer graphic technology, the pattern is transferred to the transparent OHP film.

In the above state, when the OHP film is finely drilled according to the pattern, a pattern screen that can realize a color pattern with stone powder is produced, such as silk screen printing technology, which is a kind of color printing technique.

By attaching a finely perforated OHP film screen to a thin wire mesh and fixing it firmly according to the pattern, it becomes a screen frame that can print a stone pattern in a large quantity. It can also be a means of providing mass production methods.

The detailed manufacturing method of this screen is a silkscreen production method, as shown in [Fig. 2] of the [Drawing] section on page 15.

First, the OHP film (a) with the stone pattern printed and the fine wire mesh (b) of 500 mesh or more are completely adhered to each other.Then, the hole through which the stone powder can pass if you make a delicate hole according to the stone pattern transferred on the OHP film. This is perforated (d). If you spray about 500 mesh stone powder (silica sand) on the perforated screen according to this stone pattern, only the stone powder that has passed through the perforation will be engraved in three-dimensional pattern on the substrate surface (stirring agent).

This phenomenon is based on the silk screen printing method in which the pattern and the image are engraved by the passage of ink in the silk screen printing method. When the different perforated screens are prepared and printed, a very realistic color stone pattern is easily obtained. . Here, the color stone powder plays the role of color ink, and the role of wire mesh plays a role of supporting silk screen. If the pattern screen is placed on a plate sprayed with agitating material and sprayed with powder for each color, the actual stone pattern is inscribed on the plate as it is.

3rd process (1st hardening process)

: The pattern part manufactured by the above method is soaked in the bond of the stirring agent in the lower part. The treatment is not necessary. Therefore, when the water is dehydrated, the pattern part is hardened by about 80 ° C./1 hour.

4th process (impregnated with thermosetting resin)

: After the third process, the stirring material has a bonding strength such that the form is not collapsed by gravity with a slight hardness, and there are many voids in the place where all the water evaporates and escapes.

When 40% of the thermosetting synthetic resin is added to the voids, the synthetic resin is sucked like a sponge and filled between the silica sands with the resin solution, so that when it is cured, a completely waterproof and strong material can be obtained.

5th process (secondary curing treatment)

: Heat curing material filled with synthetic resin solution at 80 ℃ / 30min. The time required for forced curing of the acrylic aqueous bond and thermosetting synthetic resin used in this technique is only 2 to 3 hours, which is not comparable with the cement curing rate over one day.

In addition, the present invention provides a method of using a binder as a thin film coating material in the manufacture of a refractory material, the method is as follows.

This method is a very important finding that the ceramic coating, which can be coated only with a thin film, can be used as a binder like a synthetic resin. The whole process is the same, and the total thickness of the stirring material and the stone pattern should not exceed 2 mm and the curing condition is 250. You only need to change the conditions of baking for 30 minutes at 30 ° C.

These conditions are carried out according to the method described in the secondary process on the surface of the flame-retardant building materials such as aluminum and tiles, and the silica sand stone pattern is 1 mm or less in thickness and sprayed with an aqueous bond crosslinking agent and settled. It is possible to obtain a plate with three-dimensional pattern seated on it. Impregnating a ceramic coating instead of synthetic resin on this plate and baking it at 250 ° C / 30 minutes can provide a completely flame-retardant plate material. It is to provide a breakthrough method that can be used.

The aqueous acrylic, which is a pattern stone manufacturing method provided by the present invention, gives a role of a crosslinking agent by adjusting the water mixing ratio to 20%, impregnating and filling the synthetic resin solution and the ceramic coating agent, the method of manufacturing the pattern screen, and the natural pattern printing method, etc. It provides the basis for building mass production system of building materials, and the introduction of various additional materials will greatly improve not only insulation artificial stone but also the manufacture and design of building materials with functions for each application.

Claims (3)

In the present invention, a method of acting as a crosslinking agent of an aqueous bond to keep a silica sand stirring material in a form without forming a mold and a synthetic resin impregnation method to obtain strong weather resistance ensure the same formability and strength as the molded product produced by the molding method. have. The heat insulating pattern stone provided by the present invention is divided into a heat insulating portion and a pattern portion, but the heat insulating portion may use a PVC foam panel or other heat insulating material, but the pattern portion follows the role of the aqueous bond crosslinking agent provided by the present invention. In making the material that serves as the thickness of the pattern portion, color silica sand is placed in the mixer and 20% aqueous acrylic bond solution is poured into 30% of the silica sand volume to form a stirring mixture of the silica sand and the bond. The reason why the mixing ratio of the aqueous acrylic bond and water is 20%, that is, 2: 8, is to appropriately reduce the adhesive strength of the bond so that it can act as a crosslinking agent so that the silica sand without any viscous force can be maintained for a while and after curing It is intended to loosen the silica sand so that synthetic resin liquid and thin film ceramic can penetrate and fill. Eventually, a large amount of voids from which 80% of the water escapes is filled with synthetic resin. After stirring the mixture mixed with this crosslinking agent to 2mm thickness on the heat insulating material plate to realize the pattern and texture, it is hardened by 80 ℃ / 60 minutes to produce a plate with a slight hardness. The plate is impregnated with 40% of the thermosetting resin. If you do so, it will be filled with synthetic resin liquid like a sponge. When it is thermally cured again under the condition of 80 ° C./30 minutes, a heat insulating pattern stone of a strong surface is completed. The present invention provides a printing method using stone powder instead of ink. In Figure 2, see Figure 2, where the OHP film (a) with the stone pattern printed on it and the fine wire mesh (b) of 500 mesh or more are fully bonded together (C), and then the hole is delicately made according to the stone pattern transferred on the OHP film. If you make a hole, the stone powder can be passed through. (D) If you sprinkle about 500 mesh stone powder (silica sand) on the perforated screen according to this stone pattern, only the stone powder that has passed through the hole is engraved in three-dimensional pattern on the substrate surface. You lose. This phenomenon is based on the silk screen printing method in which the pattern and the image are engraved by the ink passing through in the silk screen printing method. If the different screens are prepared and processed, a very realistic color stone pattern is easily obtained. . Here, stone powder plays the role of ink, and the role of the wire mesh supports the silk screen. If the pattern screen is placed on a plate sprayed with agitating material and sprayed with powder for each color, the actual stone pattern is inscribed on the plate as it is. It is important to note that the ceramic coating, which can only be coated with a thin film, can be used as a binder such as a synthetic resin, and the whole process is the same as the above process, and it should be noted that the total thickness of the agitator and the stone pattern should not exceed 1 mm. This is because the thickness of the ceramic for thin film coating is somewhat higher, there is a property that collapses and breaks, and the reaction is minimized at 1mm. In addition, only the conditions of baking at 250 ° C./20 minutes, which are curing conditions of ceramics, may be different. Spread 20% of the aqueous acrylic bond solution provided by the present invention on a plate of flame retardant building materials, such as aluminum and tiles, and agitated mixtures of color silica sand or inorganic powder, which are carried out to a thickness of 1 mm or less and the first step after a patterning process using a pattern screen. Conduct hot air cure. In the above state, when the pores are formed in the place where moisture is drained out, and the pores are filled with the ceramic liquid and hardened, a hard or large flame retardant effect is formed. In general, the ceramic coating agent for thin films sold may be baked under the condition of 250 ° C./30 minutes to obtain an inherent hardness.
