The present invention relates to a flooring material and a method of manufacturing the same, which gives a three-dimensional natural cloud pattern effect on the surface of the flooring material having surface irregularities, and more specifically, by incorporating a pigment having a light reflection effect on the transparent surface of the flooring material It is intended to give translucent effect on the surface and to give the effect of three-dimensional natural cloud pattern by the flow phenomenon due to the specific gravity difference between the pigment and plastisol (PLASTISOL).

Conventionally, the surface layer 5 is transparent on the fabric 1 (the foam layer 4 is formed on the substrate 2 or the special glass fiber layer 3) as shown in FIG. 6 to increase the appearance effect of the flooring material. After forming, the printing layer (6) by various printing methods is formed on the lower surface layer, that is, the top layer of the fabric (1), so that the printing area is projected through the surface layer (5), and the light reflection effect The method which provided the stereo effect using the pigment which has.

In addition, various methods such as controlling the gloss of the surface layer have been used to widen the range of products that consumers can choose. This is due to the simplicity of artificial patterns, the limitation of giving a three-dimensional appearance of flat patterns, and the boredom of colors. There was not enough to satisfy the consumer's desire for new and improved design with the improvement of living standard.

Therefore, the present inventors have been researching and developing a new and more improved design of the floor decoration material in view of this point, and that is the floor decoration material to give the effect of the translucent three-dimensional natural cloud pattern produced by the manufacturing method of the present invention. .

Hereinafter, the manufacturing process of the present invention and its embodiments will be described in detail with reference to the accompanying drawings.

2 is a manufacturing process diagram schematically showing the manufacturing process of the present invention, in which the plastisol (PLASTISOL) containing the blowing agent (ADCA) in the fabric 1 released from the roll state is 0.1 to 0.7 mm in thickness. Coating uniformly. At this time, the plastisol used may be polyvinyl chromide homopolymer (POLYVINYL CHLORIDE HOMO POLYMER) or other vinyl chromide (VINYL CHLORIDE), or a mixture thereof, and may also be used as sebacate, adipate, Phthalate, ester plasticizers and fillers (TiO ₂ ), thermal stabilizers, foaming agents, foam stabilizers, UV stabilizers, foaming accelerators, viscosity lowering agents, etc. The fabric 1 heated by heating at 120 to 200 ° C. for 40 seconds to 3 minutes in the heating device 20 to be gelled is cooled by the cooling device 21, and two surfaces of the fabric 1 are cooled. Or print the required pattern and color with a printing device 22 equipped with more rolls.

At this time, the printing ink used is classified into a foam inhibitory ink and a non-inhibitor ink according to the pattern, and in addition to the pigment, a solvent, a resin (RESIN) plasticizer, a stabilizer, an antioxidant, a blocking agent is added.

After printing, the printing ink is dried at 50 to 120 DEG C in a drying apparatus 23, and translucent on the surface of the fabric 1, on which the ink is dried, using the engraving rolls 24 as shown in FIGS. Transfer the plastisol, but the optimum angle (a) between the engraving roll 24 and the upper compression roll 25 is 30 ° to 60 °, the viscosity of the plastisol containing the pigment used is 300 Composition ratio is -1500 CPS (Brook-Field viscometer, 25 degreeC) is shown in Table 1 of an Example.

As described above, after the plastisol-transferred fabric surface is mixed with a pigment having a light reflection effect (manufactured by MERAL, MEARLIN, specific gravity 3.0) in order to form a translucent three-dimensional natural cloud pattern, When the fabric 1 is perpendicular to the ground as described above, the transferred plastisol flows down to its own weight and is maintained for 3 to 8 seconds so that mutual overlap occurs. As a result, the space between the transferred patterns, that is, the non-wire portion 7 is filled, and the entire surface of the fabric is uniformly applied.

At this time, due to the difference in specific gravity between the plastisol flowing down by its own weight and the pigment having the reflection effect of light in the plastisol, an interface 9 is formed between the wire part 8 and the wire part 8. 9) The three-dimensional pattern is formed in the shape of the engraving roll 24 carved into the cloud pattern 24 ', and the three-dimensional pattern fabric is passed through the heating device 20' and the liquid plastic formed on the surface thereof. At the same time as the stisol is gelled, the part printed with the foam inhibitor ink containing the foam inhibitor is delayed in the decomposition rate of the foam agent, so that the thickness layer is lower than that printed with the foam non-inhibition ink. To form.

At this time, the heating conditions are 1 to 6 minutes at 150-240 ° C. and the heated fabric is cooled by the cooling device 21 ', and mechanical embossing may be formed on the surface as needed before cooling. If necessary on the back side, the coating is to form the back layer 10 is to be a finished product as shown in FIG.

In order to make the above-described manufacturing process easier to understand, the flow chart is as follows.

The present invention as described above is printed on the base layer (2) or the special glass fiber layer (3) above the foam layer 4 by printing with a foam inhibiting ink or non-inhibiting ink to form a printing layer (b) and then heated to the foam inhibitory part Surface unevenness due to chemical embossing effect is formed depending on the non-inhibiting portion, and the line part 8 is formed with a plastisol containing a pigment having a reflecting effect, and then the overlapping phenomenon between the part lines is maintained by maintaining perpendicularity to the ground. In this case, due to the difference in specific gravity of the pigment of the plastisol containing the pigment and the plastisol which is the vehicle, an interface 9 is formed between the wire part 8 and the wire part 8, and by this interface 9 It is possible to form a three-dimensional natural cloud pattern in the shape of the engraving roll 24 carved into the cloud pattern (24 '), a new and improved design that can meet the various needs of consumers according to the improvement of living standards, Kane will be available for flooring with a peaceful look effect.

EXAMPLE

Composition ratio of plastisol with reflecting pigment

TABLE 1

The viscosity of the plastisol having the composition ratio is 300-4500 CPS (Brook-Field Viscometer 25 ° C.) and the viscosity can be adjusted according to the input amount of each raw material.

According to the present invention, unlike the conventional method, by maintaining the fabric 1 on which the ink is transferred by the engraving roll 24 vertically, the ink of the wire part 8 (the ink-impregnated part) flows down to cause overlap between the wire parts. In this case, the time required to keep the fabric vertical is the viscosity of the plastisol containing the reflecting pigment, etc., the welding angle between the engraving roll and the pressing roll (a), the size of the wire part, the gap between the wire part and the wire part (non-fired part). It is determined by factors such as the transfer amount of the ink.

The steric effect is represented by the interface 9 formed by the specific gravity difference between the specific gravity of the reflecting pigment and the plastisol which is the vehicle.

In addition, in the angle a between the engraving roll 24 and the pressing roll 25 as described above, the closer the angle a is to 0, the less the amount of transfer of ink in the wire portion 8 of the ridge is reduced to 90 °. The closer to, the greater the amount of transfer.

Therefore, the optimum angle for obtaining a good overlapping effect in the present invention is 30 ° to 60 °.

In the present invention, the length of the wire part 8 of the engraving roll 24 may be an amorphous or amorphous wire part up to 0.5 to 2 cm, as shown in FIG. 4, and the most ideal pattern is formed when the ink transfer amount is 80 to 90%. Therefore, the depth (h) of the wire line 8 should consider the transfer amount of ink, and the depth of the wire line can be up to 0.1 to 0.7 mm depending on the thickness of the printed layer, and when the depth is 0.1 mm or less, the ink transfer It is difficult to form the overlapping effect due to the small amount, and the three-dimensional formation of the intrinsic pattern is not possible due to the large amount of transition at 0.7 mm or more.

In addition, in the present invention, the non-fired portion 7 of the engraving roll 24 is suitable up to 0.05 to 0.5 mm in consideration of the overlapping phenomenon, and the non-fired portion is hardly formed when the non-fired portion is 0.05 mm or less, and the overlapping effect of 0.5 mm or more. The formation is poor.

And in order to play a role of improving the transfer amount of the transferred ink, the transfer amount enhancing projections 11 are present one by one at intervals of 0.2 to 0.7 mm, and the engraving rolls are plated with chromium (Cr) to improve durability.
