The present invention relates to a mat manufacturing apparatus, and more particularly, in the manufacture of the base sheet by applying a slurry mixture containing the rubber chip on the fiber sheet, but the manufacture by making the plywood at the same time It is related to a mat manufacturing apparatus that is simple, which is advantageous in terms of productivity and cost and has excellent non-slipness.

In general, mats are widely used for floor protection or sound insulation. In detail, floors such as cars, ships, aircrafts, trains, indoor floors, entrances or corridors of buildings, etc., are installed to have a comfort while cushioning the floors. It is installed for the purpose of sound insulation.

1 shows a cross-sectional view of a mat according to the prior art. The mat is made of a single material (synthetic resin) and may be composed of a single layer or a multilayered synthetic resin layer. However, as shown in FIG. 1, the mat is exposed to the outside and the fiber sheet (1). It is generally composed of a base sheet (3) for supporting).

As shown in FIG. 1, the mat has a nonwoven fabric or carpet-like fiber sheet 1 compared to other conventional mats, and the appearance is beautiful, and the cushioning (buffering function), touch, and sound insulation are excellent. It is very useful as a building sound insulation material and a golf mat. 1 shows a mat having a carpet-like fibrous sheet 1 in which fiber strands 1b are vertically planted on a substrate 1a.

Conventionally, in manufacturing the mat as described above, the base sheet 3 is manufactured separately from polyvinyl chloride (PVC) or rubber, and then laminated to the fiber sheet (1) and the adhesive, or the base sheet without the use of an adhesive (3) was heated to give surface adhesiveness, and then the fibrous sheet (1) was laminated and pressed and laminated.

However, in the manufacturing of the mat according to the prior art as described above, the manufacturing process of the base sheet (3) and the plywood process was carried out separately, there was a process cumbersome, in particular, the material of the base sheet (3), PVC, rubber or synthetic resin derived from As used, there was a problem in cost according to the material cost. In addition, in the case of PVC, incineration generated environmentally harmful substances such as dioxins, which was not environmentally friendly.

In addition, the mat is not only cushioning and sound insulation, but also non-slip is required, especially when installed on the interior floor of the car or building. To this end, in the related art, it is common to form the protrusions 3a integrally on the lower surface of the base sheet 3 made of PVC or rubber, as shown in FIG. 1.

For example, Korean Patent Laid-Open No. 2001-0105796 discloses a mat having a protrusion on the bottom and a manufacturing method thereof, and Korean Patent Laid-Open Publication No. 2004-0010096 discloses a non-slip sheet for a mat. Such a prior art is produced by injection molding in a mold having a groove in order to form the projection (3a), or by using a roller having a groove in the production, the productivity is reduced and the process process is also a complicated problem There was this. In particular, the protrusion 3a above has some non-slip property when the bottom surface is rubber or synthetic resin flooring material, but the non-slip property is not very efficient when the bottom surface is a nonwoven fabric or a carpet type such as an automobile. There was a problem.

On the other hand, as automobiles and other rubber products are distributed as necessities in daily life, the amount of waste rubber such as used tires is continuously increasing. However, the recycling of waste rubber is not in practical use due to the constraints such as economic feasibility and marketability, and its treatment facilities have only a few disadvantages. In particular, in the case of waste tires are currently used as a fuel for incineration, this has had a problem of generating air pollution.

The present invention is invented to solve the problems of the prior art as described above, in the manufacture of the base sheet by applying a slurry mixture containing a rubber chip on the continuously transported fiber sheet, but the production In addition to the plywood is made at the same time to provide a mat manufacturing apparatus that is simply manufactured in a continuous process and advantageous in terms of productivity and cost.

It is another object of the present invention to provide a mat manufacturing apparatus that can easily protrude a rubber chip onto the surface of a base sheet as a non-slip structure.

In order to achieve the above object, the present invention is to accommodate the base sheet forming mixture is provided with a supply tank having a main body provided with an inlet and an outlet, and a stirrer installed inside the main body and driven by a motor; Milling means which is installed in the lower part of the supply tank to flatly mill and apply the base sheet forming mixture on a semi-finished product (a product having a resin film laminated on a fiber sheet); It provides a mat manufacturing apparatus including a support plate, a scraper (scratcher) is provided at the rear end of the supply tank to scratch the surface of the base sheet forming mixture, and a base sheet curing machine for curing the applied mixture do.

In addition, according to the present invention, it is preferable that the support plate and the scraper have a height adjusting means to enable the thickness adjustment of the mat.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail. The accompanying drawings show exemplary embodiments of the present invention, which are provided merely to explain the present invention in detail, and do not limit the technical scope of the present invention.

First, the mat manufactured by the manufacturing apparatus of the present invention will be described.

The mat comprises at least a fiber sheet 10, a resin thin film 20 formed on one surface of the fiber sheet 10, and a base sheet 30 formed on the resin thin film 20. This is illustrated in FIGS. 2 to 5.

Specifically, the mat according to FIGS. 2 and 3 includes a fibrous sheet 10 on the surface, a resin thin film 20 formed under the fiber sheet 10, and a base sheet formed under the resin thin film 20. It consists of 30.

In the present invention, the fiber sheet 10 is in the form of a carpet or nonwoven fabric. 2 shows that the fiber sheet 10 is in the form of a carpet, and FIG. 3 shows that the fiber sheet 10 is in the form of a nonwoven fabric. That is, as shown in Figure 2, the fiber sheet 10 is in the form of a carpet formed by vertically weaving the fiber strands 14 in the form of a bundle on a substrate 12, such as woven, non-woven or cloth, or As shown in FIG. 3, a plurality of fiber strands 14 are densely formed into a nonwoven fabric processed into a sheet. In addition, the fiber sheet 10 in the present invention includes a representation of the pattern and color. The fiber strands 14 constituting the fiber sheet 10 include polyester, polyester, polypropylene, nylon, acrylic, rayon, silk, cotton, and the like, or natural fibers. The fiber sheet 10 as applied to the present invention is not only beautiful in appearance, but also excellent in cushioning (buffering function) and feel and excellent sound insulation.

The resin thin film 20 is formed by coating and curing a thin resin on one surface of the fiber sheet 10 by the manufacturing apparatus of the present invention. The resin constituting the resin thin film 20 can be used as long as it has bonding strength with the fiber sheet 10 after coating and curing. For example, an adhesive such as acrylic, silicone, rubber and polyurethane may be used as the resin having adhesiveness, which includes thermosetting and photocuring.

The resin thin film 20 is to provide a shielding film so that the mixture for forming the base sheet 30 described below does not penetrate into the fiber sheet 10, which is a resin constituting the mixture for forming the base sheet 30 as much as possible. It is preferable to use the same thing as the adhesive.

The base sheet 30 is formed by coating and curing a mixture in a slurry state by the manufacturing apparatus of the present invention, and the mixture constituting the base sheet 30 may include any rubber chip 32 and an adhesive polymer material 34. Any use is possible.

The rubber chip 32 is pulverized waste rubber, which is preferably a waste tire pulverized product among various kinds of waste rubbers discarded in an industrial site. Waste tires are synthetic rubbers of high-quality materials, and unlike other waste rubbers, there is no need for a special collection and sorting process, and thus recycling is very easy. The rubber chip 32 is used as the main material of the base sheet 30 to impart elasticity to the base sheet 30, and as a result of recycling the waste rubber (waste tire, etc.) as described above, at the same time to promote efficient reuse of resources. It lowers the production cost of the product.

In addition, the size of the rubber chip 32 is selected according to the thickness setting of the base sheet 30, although not particularly limited, a size in the range of 20 micrometers (µm) to 10 mm (mm) may be used. . In addition, the rubber chip 32 is irrelevant whether it is uniform in size or non-uniform. Preferably, non-uniform particles are mixed. In the case of mixing of uneven particles, the density of the rubber chip 32 in the base sheet 30 is increased, thereby improving elasticity (cushioning feeling). In this case, when the rubber chip 32 is made of only small particles, the elasticity is insignificant and nonslip is inferior. When the rubber chip 32 contains too large particles or is made of only large particles, it is not preferable to adjust the smoothness of the base sheet 30. . In addition, the rubber chip 32 may have various shapes, but preferably, the rubber chip 32 is pulverized into a shape having a sharp pointed angle rather than a curved surface. Thus having a pointed angle has the advantage that the non-slip property is very improved.

The polymer material 34 is to fix the rubber chip 32 as described above, which comprises at least an adhesive resin. Specifically, the polymer material 34 may be made of an adhesive resin alone, or other polymers may be mixed with the adhesive resin. Herein, the polymer is selected according to the type of the adhesive resin, and is selected from, for example, a crosslinking agent, a surfactant, a photoinitiator, a reaction accelerator, and the like.

The adhesive resin constituting the polymer material 34 may be, for example, an adhesive such as acrylic, silicone, rubber, and polyurethane, including thermosetting and photocuring. More specifically, the polymer material 34 is a Kumaryong resin (available from Kanto Chemical, Japan, Kolon, Exxon, etc.) as an adhesive, stearic acid as a swellable surfactant, and dibenzo as a reaction accelerator (catalyst). Thiazyl mercapto benzothiazole (DM; Dibenzothiazyl Mercapto Benzothiazole).

The mixture for forming the base sheet 30 includes the rubber chip 32 and the adhesive polymer material 34 described above as essential components. For example, the mixture for forming the base sheet 30 is based on the total weight of the rubber chip 32 20 to 50 parts by weight, Kumaryong resin 30 to 60 parts by weight, stearic acid 5 to 25 parts by weight and dibenzothiazyl mer Capto benzothiazole (DM) may be mixed in an amount of 2 to 11 parts by weight.

In addition, the base sheet 30 may be further mixed with one or more additives optionally selected from fillers, foaming agents, color pigments, and fragrances. Here, the filler may reinforce the strength of the base sheet 30, and inorganic powders such as calcium carbonate (CaCO ₃ ) and calcium hydroxide (Ca (OH) ₂ ) may be used, and the foaming agent may have a pore structure in the base sheet 30. As a thermal foaming agent, for example, p, p'-oxybis (benzenesulfonyl hydrazide), benzenesulfonyl hydrazide, toluenesulfonyl hydrazide can be formed by improving the elastic force (cushion feeling). Sulfonyl hydrazide such as; Azo compounds, such as azo dicarbonamide (ADCA) and azobisisophtyronitrile; Nitroso compounds such as N, N'-dinitrosopentamethylenetetramine and N, N'-dimethyl-N, N'-dinitrosoterephthalamide; In addition, inorganic blowing agents such as sodium bicarbonate and ammonium bicarbonate may be used, and one or two or more kinds thereof may be selectively applied depending on the type of the polymer material 34.

The mixture for forming the base sheet 30 as described above is applied and cured on the resin thin film 20 to form the base sheet 30. More specifically, the base sheet 30 is coated with a mixture for forming the base sheet 30 on the resin thin film 20 by the apparatus of the present invention, and then heat milling after milling to have a smoothness. Or it is formed by photocuring, which is laminated with the resin thin film 20 at the same time as the molding. As described above, the resin thin film 20 provides a blocking film so that the mixture for forming the base sheet 30 does not penetrate into the fiber sheet 10. That is, the mat manufactured in the present invention is composed of a fiber sheet 10, the surface layer of which can penetrate the liquid, if the resin thin film 20 is not formed, the mixture for forming the base sheet 30 in the coating / milling process It penetrates into this fiber sheet 10, and deteriorates the external appearance, cushioning property, etc. of the fiber sheet 10. FIG.

In addition, the mat as described above may have a structure in which the rubber chip 32 protrudes to the surface as a non-slip structure. This structure is very useful when installed on the indoor floor of a car, ship, aircraft, train, etc. where non-slipness is particularly required and when applied as a golf mat.

4 shows that the rubber chip 32 protrudes from the surface of the base sheet 30. Referring to FIG. 4, the rubber chip 32 protruding to the surface imparts excellent non-slipness to the mat. Specifically, the rubber chip 32 has a non-slip property by its own material, and is distributed in the form of particles to give more improved non-slip property. In particular, when the floor surface itself is a nonwoven fabric or a carpet form, such as a car, the non-slip property is very excellent as the protruding rubber chip 32 is sandwiched between the fibers of the floor surface. At this time, the bottom surface of the vehicle and the mat of the present invention will have a velcro structure called a conventional "sticky". In addition, as described above, when the rubber chip 32 has a shape having a sharp point, non-slip property is further improved.

In addition, the mat is a fiber sheet 10, the resin thin film 20 and the base sheet 30 as an essential component, these may be applied to two or more in the mat according to the purpose and use of the mat.

Figure 5 shows the two sides are made of a fiber sheet (10, 10 '). Specifically, the fibrous sheet 10, the resin thin film 20, the base sheet 30, and the fibrous sheet 10 ′ may be sequentially stacked. At this time, as shown in Figure 5, in the mat according to the fourth embodiment of the present invention, the resin thin film 20 is not formed between the base sheet 30 and the fiber sheet 10 ', In the case where the mixture for forming the base sheet 30 is uncured, the fiber sheet 10 'may be laminated and pressurized thereon, so in this case, it is not necessary to form the resin thin film 20 for the shielding film. Such a mat is particularly useful as a sound insulating mat provided for the purpose of sound insulation between the floors and walls of buildings because the fiber sheets 10 and 10 'having excellent sound insulation are bonded to both sides.

The present invention is intended to simplify the manufacturing of the mat described above, in particular to make the base sheet 30 and plywood at the same time, it is possible to adjust the thickness of the base sheet (30). In addition, the supply of the fiber sheet 10, the coating of the resin, the application of the mixture for forming the base sheet 30, and curing thereof proceed in a continuous process. Then, the rubber chip 32 is projected to the surface of the base sheet 30, the rubber chip 32 by a simple operation.
