DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, the nonwoven fabric sheet 10 is wound in the form of a roll, and the water film tape 100 to be described later is formed by the nonwoven fabric molding apparatus 1 of the present invention.

First, a vinyl layer 20 is pressed on the surface of a nonwoven fabric sheet 10 of the present invention and an adhesive layer 30 is formed on the vinyl layer 20, When the nonwoven fabric sheet 10 travels through the hopper in the nonwoven fabric forming apparatus 1, the release paper of the nonwoven fabric sheet is separated and traveled.

As shown in Figs. 1 and 13, the nonwoven fabric sheet 10 is unwound from the hopper (not numbered) of the nonwoven fabric forming apparatus 1 and traveled. First, in the superabsorbent resin feeding section 2, And the superabsorbent resin on the nonwoven fabric sheet 10 is compressed in the compression roll 3 to a predetermined thickness and then cleaned to remove foreign matter by the brush roll 4 and then to the vacuum inhaler 5 The nonwoven fabric sheet 10 is folded at 1/2 in the 1/2 folding device 6 and the folded back is pressed to the next pressing roll 7 and the sewing 8 ) And a cutting (9) device.

The nonwoven fabric sheet 10 is made of a fabric by combining fibers or yarns with a suitable physical or chemical action with appropriate moisture or heat to form a combination of fibers. The nonwoven fabric may be formed into a flat structure by tangling various fibers such as natural, chemical, glass, metal, etc. according to their mutual characteristics and forming a sheet-like web and combining them by mechanical or physical methods. Is used in consideration of functions of filtration, formability, touchability, and absorbency in the present invention. The filtration property is a property applicable to filtration of air and water, and influences drainage after water is absorbed. A specific example of the nonwoven fabric used in the present invention is a nonwoven fabric impregnated with 23 g / nonwoven fabric and 20 g / adhesive.

1 and 13, a resin is applied to the surface of the nonwoven fabric sheet 10 rolled up in the form of a roll and a resin is supplied to the surface of the nonwoven fabric sheet 10 and the adhesive liquid is applied onto the resin in the adhesive liquid supply 3, do. Then, the resin and the adhesive liquid are compression-molded on the nonwoven fabric by a means such as thermocompression in the compression roll 4.

In addition, a superabsorbent resin is applied on the nonwoven fabric sheet 10 having passed through the compression roll 4, and the superabsorbent resin is applied on the superabsorbent resin by the brush roll 6 And some of the unbonded resins are removed or reduced in the vacuum suction roll 7.

2 and 3, an adhesive layer 30 is formed on the vinyl layer 20 and the vinyl layer 20 on the nonwoven fabric sheet 10 that has been subjected to the above processes, and the adhesive layer 30 The super absorbent resin 40 is adhered to a certain thickness. The adhesive layer 30 prevents the superabsorbent resin 40 from being uniformly adhered (coated) and is prevented from being pushed to one side, and is uniformly applied to inflate the water absorbent resin 40 uniformly.

2, the vinyl layer 20, the adhesive layer 30 and the superabsorbent resin 40 are not coated on the edges in the longitudinal direction of the nonwoven fabric sheet, So that the water absorbent resin is not applied.

The vinyl layer 20, the adhesive layer 30, and the superabsorbent resin 40 may not be applied to the nonwoven fabric sheet 10 at intervals in the longitudinal direction of the nonwoven fabric sheet 10, so that the sewing may be performed.

The nonwoven fabric sheet 10 to which the superabsorbent resin is applied is cut into a predetermined length by the blades in the cutter 1 of the conveyor 8 to be laminated on the laminate 10.

In the present invention, the application of the superabsorbent resin (40) to the nonwoven fabric sheet (10) is uniformly applied to the surface of the adhesive layer (30) by a resin powder application device such as a spray, screw or roll. The superabsorbent resin (40) has a particle size of approximately 35 to 200 mesh.

The superabsorbent resin 200 used in the present invention is capable of absorbing only water different from other types of absorbers, has a high absorption rate and is excellent in ability to maintain an absorbed state, , It does not discharge water well even if pressure is applied.

Next, the nonwoven fabric sheet 10 coated with the superabsorbent resin 40 is folded in the width direction so as to position the superabsorbent resin 40 inward as shown in Fig. 4 and sewed by the seam 50, As shown in Fig. 6, the end in the longitudinal direction is also sewn by a seam line 50, and is molded into a bag shape to constitute a water film tape 100. Fig. That is, the water film tapes 100 are produced as a single body.

The water film tape 100 is sandwiched in the gap 210 of the door 200 as described later so that the water is infiltrated into the superabsorbent resin 40 of the water film tape 100 and the gap 210 ) Can be used to block (block). In order to effectively exhibit the function of the water film tape 100 according to the present invention, the auxiliary film forms the crease vinyl 60 and the auxiliary film forms the vinyl film 70 as described later.

As shown in FIGS. 7, 8, and 9, the crease vinyl 60 and the auxiliary film are laminated on both sides of the water film tape 100 having the superabsorbent resin 40 built therein, .

Further, an adhesive tape 80 on which a release sheet (not shown) is formed is adhered to one side of the water film tape 100.

15, a hook groove 90 is formed in the water film tape 100 and a hoof type bracket 91 is coupled to the hook groove 90 so that the water film tape 100 is inserted into the door gap So as to be caught and held by a door formed in the door or the door.

After the release tape (not shown) of the adhesive tape 80 is removed, the water film tape 100 formed as described above is inserted into the gap 210 of the door 200 as shown in Fig. 10 .

The water film tape 100 is sandwiched between the ground 220 and the gap 210 of the door 200 and is inserted into a gap of a predetermined height on the left and right sides of the door 200, Even if it reaches a predetermined height of the indoor unit 200, the inflow of water into the room is prevented. The water film tapes 100 can be formed on the entirety of the left and right gaps of the door 200 as required and the water film tapes 100 can be fitted in the gaps in the entirety of each side of the door 200

Therefore, when water is brought into contact with the water-absorbent resin 40 through the nonwoven fabric sheet 10 in a state where the water-barrier tape 100 is fitted in the gap 210 of the door 200, The resin 40 has a high absorption rate of water and is excellent in the ability to maintain the absorption state. As the resin 40 absorbs water, it rapidly changes into a gel state. As shown in FIG. 12, the water film tape is kept inflated while being converted into a gel state. Even if it does not discharge water well. That is, it is possible to block or delay the entry of external water into the gap 210 of the door 200.

Since the water is discharged over time after the delay as described above, a great effect can be obtained as compared with the case in which the water flows into the room without the water film tapes 100 to sink the room.

Further, in the present invention, it is possible to effectively prevent wind and rain entering between gaps in a window or a veranda of a building, and furthermore, when the water-damaging tape 100 is mounted in a gap under a parking lot or a warehouse shutter door, And the like.

14, a plurality of U-shaped locking grooves 90 are formed in the rear of the water film tape 100, and a horseshoe-shaped bracket (not shown) 91 are sandwiched and fixed so that the water film tapes 100 are inserted into the gaps of the doors and held by the gates formed in the gates or the ridge.

The horseshoe-shaped bracket 91 is made of an iron plate, and the front side of the horseshoe-shaped bracket 91 is elastically stretched in a clip shape. The horseshoe bracket 91 can be restored to its original position due to the elastic restoring force, So that it can be held resiliently on the circumferential surface of the hook groove 90. As shown in Fig.

Accordingly, since the horseshoe-shaped bracket 91 is fitted in the hooking groove 90 and is held and fixed in a resilient manner, it can be securely held and fixed to the door or the hanger of the door, so that the water film tape 100 is separated from the door or the door There is no escape.

The present invention is not particularly limited to the length of the water film tape 100 and the number of the hook grooves 90 formed on the water film tape 100 is also not particularly limited.
