The present invention relates to a mat lower formed paper having a new form and properties and mat using the same.

Conventional mats have an upper part that exhibits external functions such as color, pattern, touch, and cushion, and a lower part that has a complementary function such as supporting the upper part, stabilizing a shape, or preventing slipping of the mat by increasing sliding or adhesion of the mat. It is composed of a formation place.

Underlaying paper for mat may vary depending on the purpose or purpose of the mat, but the conventional general downlaying paper is widely used PVC sheet or synthetic rubber, and especially for public places such as offices, or in the case of a car mat, most of these materials are used. have.

These materials have a heavy weight, good adhesion and relatively inexpensive shaving, but they are unpleasant due to the characteristic smell of synthetic rubber or PVC sheet, and cause serious environmental pollution or unsanitary problems at the time of disposal, and it is difficult to avoid the exterior of consumers. It's time.

In addition, a plurality of protrusions or irregularities are formed in order to prevent slipping or separation of the main forming paper, and the process for this is a high process cost because the forming paper is molded or injected into a sheet for each mat.

In addition, to form a plurality of projections or unevenness takes a lot more raw materials than necessary to increase the weight and handling is inconvenient during cleaning or disadvantageous to vehicle fuel economy.

The present invention is to provide a new type of substrate for forming the mat and the mat using the same, to improve the disadvantages while maintaining and reinforcing the important function of the above-mentioned substrate.

The present invention provides a mat-form substrate for improving the adhesion and excellent sound-absorbing function and lightweight, environmentally friendly, luxury and economical in a new form, the present invention provides a manufacturing technology for producing such a substrate for the mat, The present invention provides a mat manufactured by using the substrate.

The present invention relates to a new type of mat-forming paper in which short fibers are planted and a mat using the same.

(1) First, the mat underlaying paper will be described.

First, the present invention is characterized by the fact that the adhesive is applied to one side of the base of the base forming paper to form a short fiber (pile), so that the short fibers (piled) that are planted on one side of the base of the base forming paper are formed perpendicular to the surface of the base. It relates to a base forming paper for mat.

Second, the present invention is characterized in that the short fibers planted on one side of the substrate of the base forming paper is partially planted by the mark of the pattern, letters, trade names, trademarks and the like.

Third, the present invention is characterized in that at least one of the short fibers planted on one side of the base of the base paper is selected from PET, PTT, NYLON6, NYLON66, the thickness of the fiber is 1 to 100 D, the length is 0.5 to 10 mm.

Fourth, the present invention is characterized in that the substrate of the lower forming paper is selected from non-woven fabrics, fabrics, resin impregnated fabrics, PVC, synthetic resin sheet.

Fifth, the present invention is characterized by providing a mat for a home, a public place, an office or a vehicle, characterized in that the carpet is coupled to the upper portion of the mat forming paper for.

The structure of this invention is demonstrated more concretely.

1 is a cross-sectional view of the bottom forming paper of the present invention.

The underlying paper of the present invention is that it has a single fiber 13 bonded to an adhesive 12 at one end surface of the substrate 11.

Here, the base material refers to fabrics for making the lower formation paper, and non-woven fabric fabrics, fabric fabrics, pvc sheets, tpu sheets, synthetic rubber sheets, etc. are applicable. As for the short fiber used as a mat undercarriage paper, 1-100 denier is suitable for fineness, More preferably, it is 15-70 denier, 0.5-10 mm is suitable for an island length, More preferably, it is cut | disconnected to 2-5 mm.

In the present invention, a feature of the base forming paper for the mat is anti-slip.

In the present invention, the lower mat forming paper is configured to form one surface of the lower mat forming paper in a form perpendicular to the surface (vertical or close to vertical) with a single fiber of a thick denier. The denier short fibers formed in a vertical shape penetrate and closely adhere to the ground surface on which the mat is placed and are prevented from sliding in all directions by the high frictional force of the thick short fibers. Can be.

In the present invention, the characteristics of the mat lower formation paper is to be able to express a variety of patterns by the hair transplant. In the present invention, a characteristic of the mat lower formation paper is to form a partial surface instead of the front surface with a specially designed pattern, letters, trade names, trademarks, etc. in the vertical arrangement of the short-length denier fibers. This can make the appearance of the mat beautiful, and the letters and logos can be promoted as advertisements.

On the other hand, it can also be formed by planting short fibers on the entire surface.

More preferably, it is partially planted. This is because, even with partial planting, the main anti-slip and sound-absorbing functions of the present invention can be secured, various aesthetic effects can be obtained, and the effect of reducing raw material consumption can be obtained.

In the present invention, the characteristic of the mat undercarriage is light weight. In general, the existing synthetic resin sub-forming paper forms a plurality of protrusions or unevenness to prevent slippage, and heavy resins require a high specific gravity for the purpose of forming protrusions or unevenness. According to the present invention, high elastic fibers having a low specific gravity are planted on a general nonwoven fabric treated with resin, and thus weight reduction can be achieved.

In the present invention, a characteristic of the mat lower formation paper is a sound absorption function. Unlike forming protrusions or irregularities in conventional injection moldings such as synthetic rubber or pvc, in the present invention, short fibers are overlapped with the lower part of the mat lower part forming paper, so that many voids are formed and sound absorption space is formed. Therefore, the noise can be reduced.

The present invention provides a new type of mat forming paper and a mat using the same, in order to fully exhibit the object of the invention of the mat forming paper, the choice of adhesive, which ensures durability among various technical features, the adhesive effectively Take a closer look at how to choose a method that can be partially applied, and how to choose short fibers to be planted.

(A) the choice of glue

The lower mat is formed by attaching high elastic short fibers (PILE) upright by cross-linking the adhesive to give a function, and the short fibers should be in close contact with the ground where the mat is laid with strong friction force. The strong adhesion to the substrate surface should be maintained firmly even after long use. In addition, physical properties should be maintained mainly in water for a long time, or in a high temperature or heat environment.

There is often a water-soluble acrylic adhesive used in the wool process. It is inexpensive, easy to process, but weak in adhesive strength and easily swells in water. In addition, formalin, etc. may be added to reinforce these vulnerabilities, but it is not preferable because it may contain harmful effects.

Therefore, in the present invention, a polyurethane adhesive is applied, which has a strong adhesive force and has a strong water resistance, so that it is stable without any change in properties even when it is in contact with water for a long time, and in particular, an adhesive suitable for a purpose such as a vehicle can be selected and used.

The composition of the reaction curable polyurethane adhesive of the present invention,

* Based on 100 parts by weight of the urethane adhesive having a solid content of 35 to 80%,

* 5 to 20 parts by weight of a urethane crosslinking agent having a solid content of 60 to 99%,

* 0.5 to 3 parts by weight of accelerator,

* 5 to 20 parts by weight of pigment and

* It is preferable to contain 10-70 weight part of solvents.

The reaction curable adhesive applied to the present invention has a characteristic that the monomolecular chain is long chained while reacting with the crosslinking agent to exhibit normal physical properties, and the viscosity at the time of use is usually 5000-15000 cps, and the viscosity of the POT LIFE (over time) Therefore, the adhesive formulated before the viscosity rises and reaches the initial time of 2 times) is preferably exhausted. It is preferable.

In the composition of the polyurethane adhesive, the crosslinking agent serves to connect the monomolecular chain, and specific examples thereof include DS-88 of Dong-A Chemical Co., Ltd., and the accelerator promotes the reaction rate of the adhesive and the crosslinking agent. As a specific example, TLX-01 of Daehyup Co., Ltd. may be mentioned, the pigment is a normal liquid pigment, and the solvent may be MEK (methyl ethyl ketone).

In addition, the composition of the reaction completed polyurethane adhesive,

* 100 parts by weight of a urethane adhesive having a solid content of 35 to 80%,

* 5 to 20 parts by weight of pigment and

* What contains 10-70 weight part of solvents is applicable.

The reaction completed type is an adhesive that shows normal physical properties only by drying of a solvent (solvent) since many reactions are already completed.

In addition to the reaction-curable polyurethane adhesive or the reaction-completed polyurethane adhesive applied in the present invention, it is possible to use a water-soluble acrylic adhesive or a water-soluble urethane adhesive, but it is not as effective as a polyurethane adhesive in terms of water resistance, adhesive strength, and environment.

(B) Application method of selected adhesive and gravure roll

In the present invention, the front surface of the conventional KNIFE OVER ROLL method is also possible.

Here, partial planting is demonstrated concretely.

Partial flocking is to transplant partial sections with regular patterns or typefaces so that they can achieve beautiful appearance effects and advertisements and propaganda effects without excessive physical properties or high cost. Therefore, only the part of the designed part is applied and planted with the adhesive.

Part of the conventional conventional coating method of the adhesive is a flat screen cotta, a cylindrical rotary screen method, but the reaction-curable polyurethane adhesive monomolecular chain (短 分子 鎖) reacts with time after compounding at a constant ratio Polymerization is gradually hardening, and even the reaction complete type is gradually hardened by the natural evaporation drying of the dilution solvent. Therefore, when used on the screen, it gradually blocks the through-holes when the screen is used. It is difficult to clean at the end. Therefore, it is not possible to apply the polyurethane adhesive to a flat screen or rotary screen coater, which is a conventional adhesive coating method.

The present invention provides a new coating method of the improved GRAVURE cotta.

Conventionally, GRAVURE cotarol has been applied efficiently to apply a small amount of liquid such as surface treatment or printing.

Figure 4-1-1 is to illustrate the existing surface printing or thin-film pattern is a drawing of the GRAVURE ROLL cotta with the pattern portion treated in a mesh form. The roll treated in the form of a mesh is used to prevent the flow of the liquid and to maintain uniformity in the application surface, but it is disadvantageous for applying a relatively large amount required in the present invention.

And since there is no amount of adhesive remaining in the inner part (h) of each mesh, as shown in 4-1-2 and 4-1-3, it is possible to apply a very small amount of adhesive that can bond short fibers after transferring to the substrate. The adhesive strength falls.

The main technical features of the present invention is that the polyurethane adhesive is applied to resist strong adhesion and durability, and the method of applying the adhesive is particularly applied by GRAVURE Cota, which was developed to satisfy the partial coating method.

In the present invention, the surface of the gravure roll is treated with a tube without a mesh as shown in Fig. 4-2-1, or when the mesh is made into a mesh size of 30 mesh or less, preferably 10 mesh or less is useful. As a result, as shown in FIGS. 4-2-2 and 4-2-3, the adhesive is evenly applied and planted as a whole to prevent local (h) adhesion degradation.

When the pattern to be treated is large when the adhesive is applied, the spread of the adhesive may occur when the adhesive is pressed for the transfer of the adhesive. Therefore, the liquid protection sheet to prevent the liquid from moving should be placed in the pattern. At this time, the interval of 2 to 3 mm was appropriate. The border line i in the pattern of Fig. 4-2-1 shows a beam.

The depth of the pieces is 0.5mm to 5mm but preferably 2mm to 4mm. The surface of the roll that is not engraved is preferably DOCTOR KNIFE and polished with precision of 3/1000 or more to minimize the remaining adhesive when removing the margin liquid.

(C) Selection of PILE

One of the main functions of underlay paper for mat is to make it adhere to the ground.

Thus, the function of preventing adhesion or slippage in the present invention is based on short fibers which are erected upright in a vertical shape (vertical or almost vertical) to the surface of the substrate. These are selected from short fibers of PET, PTT, nylon6, nylon66 with high elasticity and strong friction, and by cutting them into suitable lengths, the hair-planting process of the present invention can be smoothly performed.

Short fibers are very thick and long. Physical properties required in the present invention should have good adhesion and friction. Generally, the friction is proportional to the thickness of the fiber and inversely proportional to the length. On the contrary, the bond strength decreases as the length of the short fiber increases.

Therefore, it is necessary to select the fineness or the fineness to be applied. As a hair transplanting material for the mat forming base, the fineness is 1 to 100 denier, more preferably 15 to 70 denier, and the fineness is 1 to 10 mm, more preferably. It was cut into 2-5 mm.
