Method for manufacturing artificial marble pannel using back-up material

The present invention relates to a method of manufacturing artificial marble top plate using a back-up material. More specifically, back-up for general purpose plastic resin (Rrsin), natural wood and wood powder, plywood, rust-free metal alloy, cement inorganic materials, prefabricated building materials such as sandwich panels, etc. (Back-up) relates to a method of manufacturing artificial marble top plate using a material for.

In general, a sink is a kitchen utensil installed in a kitchen of a home or a restaurant and used to wash food preparation, dishes, fruits, and vegetables, and the sink includes a sink and a counter top having one or more sink balls; It is composed of a storage cabinet having a plurality of storage spaces at a predetermined height in the lower portion of the upper plate.

The top plate of the sink configured as described above is manufactured through the following production process using a plate of acrylic artificial marble. Mixing process-> Slurry feeding process-> Casting process-> Post-processing process-> Quality inspection and attaching protective film to the surface-> Storage and shipping process Will go through.

However, the conventional acrylic artificial marble used as the material of the sink top plate is MMA, which is one of the main raw materials used to make the acrylic artificial marble. Due to the high price of PMMA resin, the cost of raw materials is rising in the production of tops of artificial marble.

Therefore, the present invention is to solve the above problems, an object of the present invention is to utilize a variety of materials that are relatively inexpensive by utilizing the advantages of good reactivity among the intrinsic properties of the MMA monomer (Monomer) and excellent adhesive strength when reacting with other materials It is to provide a method of manufacturing artificial marble top plate that uses them as a back-up material.

As a technical idea for achieving the above object of the present invention

A first step of cutting back up material to a desired standard;

A second step of fixing the refined back up material on the caster;

A third step of feeding a slurry onto the upper plate of the material and then adjusting the thickness of the upper plate material while adhering the upper film to the upper portion of the slurry;

It provides a method of manufacturing an artificial marble top plate using a back-up material, characterized in that it comprises a fourth step of post-processing the resultant.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

Prior to the description of the present invention, the material for Back Up to be used for artificial marble includes the following ranges.

1.Plastic Resin: Slim or top plate (UPE, PE, PP, PVC, HIPS, PS, ABS, FRP, BMC, SMC, etc.)

2. Plywood processed with natural wood and wood powder: Counter tops such as sinks, sinks, desk tops, dining tables (processed products made of wood powder such as wood, plywood, PB, MDF)

3.Metal alloy without rust without sagging: Slim type (Zinc alloy, stainless alloy, aluminum alloy, etc.)

At this time, the metal is a material having no bending and high elastic strength and no sag phenomenon, and the artificial marble is coated on the metal in a slim type by pouring an artificial marble slurry (Slurry) of about 3 to 6 mm on the upper surface of the metal. It could not be used on its own because of its sagging phenomenon, and metal could not be used due to its weakness of humidity. However, through the complementary action, it is possible to make slim artificial marble application products that can produce various colors that are light and strong in water resistance as bathroom or toilet ceiling materials. Here, the main use of the slim type is used in bathrooms, bathroom ceilings, interior walls of buildings, and the like.

4. Inorganic materials such as cement: Wall adoption (replacement products for tiles) (cement artificial stone, natural stone, tile, etc.)

5. Prefabricated building materials such as sandwich panel

1 is a flow chart showing the production process of the artificial marble top plate using a back-up material according to the present invention.

1) Cutting the material for the back (Back Up) to the desired standard (S10).

In the step (S10), the width of the upper plate size compared to the size of the plate top plate is cut to about 10% to 30% by referring to the specifications of the artificial marble plate to be produced.

At this time, if the thickness of the back up material is artificial marble plate thickness of 12.3mm, the thickness of the back up material uses a thickness of about 4mm ~ 10mm as necessary.

In addition, when producing for the sink top plate to cut the sink bowl (Sink Bowl) 10 ~ 20mm larger than the size to be attached to cut so that the material for the back up is not expressed to the surface.

2) Fix the back up material to the desired position well (S20).

In the step (S20), when producing the top plate for the table and desk TOP as shown in Figure 2a when the back up plate 11 is placed in place, each sheet of the back up plate 11, 10 ~ 20 of the total length While maintaining the interval (12) of the length corresponding to the% set the plate material of the back-up (Setting). Reference numeral 13 denotes a portion to be cut.

At this time, in the case of the sink top plate, as shown in Figure 2b, the area (A) occupies the area (B) occupies the artificial marble and the material (Teflon) that is good to release mold area (Bowl) occupies the area (A) 5mm less than the size of the cut and set up the center of the sink bowl (Sink Bowl) from the back plate (11) to save the amount of acrylic artificial raw material consumed by the area of the sink ball.

In the case of the integrated type, as shown in Fig. 3, the sink top plate 14 for apron and the back plate 16 are prepared in advance using the same product, and the width of the sink top plate after scratching the adhesive surface. After setting the back and front jaw to the correct position on the basis of the fixed with a clamp or a vacuum pad (Vacuum pad) (17).

In addition, the general plate type that is not integrated may be produced in the same way as the existing plate production method after fixing the material for the back up in the belt caster (Belt Caster) (for the purpose of secondary processing, or does not need bonding) Only for top plate use).

3) After feeding the slurry (Slurry) to the upper plate (adhesive film) to the upper film (Upper Film) on the slurry and at the same time adjust the thickness of the upper plate (S30).

4) Finally finish (S40).

In the step (S40), after finishing the cutting (Sutting) to only the standardized size or custom size (Special Size) only the length of the integral top plate becomes a finished product.

At this time, the bottom surface is used as the basis of casting, except for artificial marble using a back-up material.

In addition, unlike the conventional one-piece artificial marble top plate using the back-up material, the upper surface as the production point is used as the surface. This is because the back up material is attached to the bottom.

Here, in the case of the back-up material, the adhesive strength is increased as the surface of the back-up material becomes stronger when reacting with the acrylic artificial marble.When selecting the material for the back-up, select the material embossed on the surface of the back-up material. Do not use materials coated with film.

As described above, the artificial marble manufacturing method using various materials for the back up in the present invention is almost the same as the existing horizontal continuous production method, but there are some parts requiring attention.

First, low-weight artificial marble chips (Marble Chip) are used.

In the existing method of artificial marble production, the ratio of artificial marble chips is about 1.6 to 1.8, and the settling of artificial marble chips occurs in the horizontal continuous production method, so the bottom surface is used as the basis of casting time. In the production method utilizing the material, the upper film is fixed while the back up material is fixed to the bottom of the belt and the artificial marble slurry is fed on it to adjust the thickness. Let's do it.

In this case, when using the back-up material, unlike the existing, the bottom surface cannot be used as a low-weight artificial marble chip (Marble Chip) without sedimentation should be used. In the production of low specific gravity marble chips, the ratio of inorganic fillers is lower than before, so in the case of Pin Mill (Crusher), which produces small particles of 40 to 120 mesh, friction heat is generated during the shredding process. As a result, the resin layer on the surface of an artificial marble chip is melted, and chips are stuck to each other.

To prevent this, increase the content of crosslinking agent by 10 ~ 30% compared to the existing one when producing original chips of marble chips, or select crusher with less frictional heat when crushing.

In addition, the ratio of low specific gravity marble chips (Marble Chip) is 1.4 ~ 1.7 level to produce and use the appropriate low specific gravity marble chips (Marble Chip) does not occur at all.

Second, be careful not to make out materials for back up during processing.

For 100% standardized products or custom sizes, order production should be done. That is, because the material used for the back up should not be exposed to the outside, the user can not cut the plate arbitrarily or pick up the seat of the bowl of the sink top plate for post-processing. Artificial marble plate using back-up material should produce only finished products of standard size or customized size so that users do not need secondary processing.

Third, in horizontal production, it can be produced by continuous method or sheet-type horizontal cell casting.

Fourth, the top plate round chin (R) treatment is to be adjusted in the upper plate as opposed to the existing production method, there are two methods as the method.

 1) As shown in Figure 4a, when cutting the center portion of the plate cast the back plate 11 in the same color and production conditions as the top plate 2 (A) (B) per 1 set of sink top plate back plate I can make it. FIG. 4B shows an example in which round R is subjected to the luther processing in the plate production and processing of the back plate 11.

2) Also, as shown in FIGS. 5A and 5B, by applying a model of a thickness controller 21 for adjusting the thickness of the slurry, the round plate R is formed on the upper plate itself. do. Since 10 ~ 40% slurry is overcharged in front of the thickness controller 21, the slurry is pushed forward to change the shape of the thickness controller. R) is formed.

In addition, let's take a brief look at the front of the sink top of the sink in the present invention.

In the case of apartment short delivery, there is a type without a nose in the front of the top plate (Fig. 5b), but the general type may require a water nose. If you want a nose (Fig. 5a) to give the desired change in the shape of the thickness controller (Thickness Controller) 21 in the same manner as when making a round (R) for the back so that the nose nose 22 is made on the top plate.

According to the manufacturing method of the artificial marble top plate using the back-up material according to the present invention as described above has the following effects.

1) In the case of artificial marble sink top plate (12.3T), it can save 40% of raw materials compared to 100% acrylic plate.

In other words, the artificial marble using back-up material can be used in rental apartments that used low-grade BMC or stainless steel tops or apartments built in the province because they cannot be used due to the high cost.

2) In the case of high-rise apartments, light artificial marble tops can be used to reduce the fatigue of the building. That is, the specific gravity of 100% acrylic artificial marble is 1.7 to 1.8, and the specific gravity of acrylic artificial marble for back up is 1.0 to 1.3.

3) Since the sink neck is made of wood, it is easy to bond with the wood part for the back up.

4) Slim type can take full advantage of the quality of artificial marble quality itself which can produce high quality. In addition, it is possible to develop a variety of applications, such as bathroom and toilet ceiling materials that require water resistance and walls that can be upgraded while taking up a little space.
