The present invention relates to a functional flooring material and a manufacturing method comprising a nanofiber layer, and more particularly to a flooring material comprising a surface layer impregnated with a non-woven fabric made of nanofibers impregnated resin on a decorative plate and a manufacturing method thereof.

Figure 2 is a flooring material with improved surface texture according to the Republic of Korea Utility Model No. 344,733, the bottom material from the bottom layer (6), base layer (1), upper layer (2), printing layer (3), transparent upper layer from below (4) and the surface treatment layer 5 containing the beads.

The surface treatment layer 5 is a mixture of spherical polyurethane or polyacryl beads in a thermosetting or ultraviolet curing paint, and when laminated to the surface layer of the flooring material, the round shape of the beads is naturally expressed on the surface to form fine irregularities. This results in no stickiness or slipperiness on the flooring surface.

Specifically, the present invention is a polyurethane or polyacryl beads, preferably a polyurethane or polyacryl beads having a diameter of 1 to 50 microns in a thermosetting paint or ultraviolet curable paint such as polyurethane or polyacryl. 1% to 50 microns is applied to the surface of the warning-bound flooring and non-cushioned heavy-duty flooring or tile product, which is cushioned by using a known knife coater, reverse roll coater, air knife coater, etc. Lamination to a thickness of about to provide a flooring with improved surface texture.

However, the beads used in the cured paint realize a good effect that initially does not feel slippery, but as the cured paint layer wears out by walking over time, the beads in the cured paint layer are lost.

Accordingly, an object of the present invention is to solve the problem of non-slip weakening due to the loss of beads due to the wear of the curing paint according to the above-mentioned walking, and to improve the physical properties and appearance image of the nonwoven fabric made of nanofibers. It is to provide a flooring material and a method of manufacturing the same that greatly improve the non-slip effect and excellent design.

In order to achieve the above object, the present invention includes a base layer, a makeup layer, and a surface layer from below, the surface layer provides a flooring material characterized in that the non-woven fabric made of nanofibers impregnated with a resin.

The diameter of the nanofibers used in the present invention is 10 nm to 1 mm, the thickness of the nonwoven fabric is preferably 1 to 500 ㎛. This brings about the effect of shielding the pattern of the cosmetic layer when the diameter of the nanofibers and the thickness of the nonwoven fabric increases.

Nanofibers used in the present invention is at least one selected from polyacrylonitrile (PAN), cellulose (Cellulose), polyvinyl alcohol (PVA), polyester (Polyester), nylon (Nylon), polyimide (Polyimide).

The impregnated resin used in the present invention is at least one thermosetting resin selected from melamine, acrylic, polyester resin.

In addition, the present invention comprises the steps of forming a nonwoven fabric by directly spinning the nanofibers on the makeup layer after plywood the base layer and the makeup layer; It provides a method for producing a flooring material comprising the step of forming a surface layer by impregnating and curing the thermosetting resin on the nonwoven fabric.

In addition, the present invention comprises the steps of impregnating a non-woven fabric made of nanofibers with a thermosetting resin to prepare a surface layer; It provides a method for producing a flooring material comprising the step of plywood in order from the base layer, the cosmetic layer, the surface layer from below.

Functional flooring material comprising a nanofiber layer according to the present invention has a non-slip resistance and heat resistance and excellent appearance through a nonwoven fabric of the fiber layer. Specifically, the non-slip flooring made of the nanofiber nonwoven fabric prepared according to the present invention has non-slipness through the irregularities generated between the fibers, can impart a design effect through the appearance of the nonwoven fabric, and also of the polymer forming the fiber It has physical properties, such as heat resistance and water resistance, by a characteristic.

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

1 is a cross-sectional view of the flooring according to the present invention, the flooring is composed of a base layer 10, a makeup layer 20, the surface layer 30 from below.

The base layer 10 may be a wooden base material such as plywood, medium density fiber board (MDF), high density fiber board (HDF), particle board (PB), or the like, polyvinyl chloride (PVC), polycarbonate (PC), or polyvinyl acetate. Synthetic resin base materials, such as (PVAc), etc. can be used.

As the makeup layer 20, a layer printed on a synthetic resin sheet, a printing paper, a wood-based sheet, or the like may be used.

The surface layer 30 is impregnated with the impregnated resin 32 of the nanofiber nonwoven fabric 31 made of nanofibers.

The nanofibers constituting the nanofiber nonwoven fabric 31 are made of polymers such as PAN, Cellulose, PVA, Nylon, Polyester, Polyimide, and the like when the nanofibers made of natural polymer Cellulose are applied to the present invention. Can be given one more layer.

The nanofiber nonwoven fabric 31 is obtained directly in the form of a nonwoven fabric through melt blown spinning or electrospinning, wherein the diameter of the nanofibers can be variously adjusted from 10 nm to 1 mm.

The nanofiber nonwoven fabric 31 used in the present invention is manufactured by using a fiber having a thickness of 1 to 500 µm in order to reproduce the design of the makeup layer while obtaining non-slipness and physical properties of the fiber.

The impregnated resin 32 to impregnate the nanofiber nonwoven fabric 31 serves to impart adhesion between the nanofiber nonwoven fabric 31 and the cosmetic layer 20 while maintaining the design of the cosmetic layer. The resin used as the impregnated resin 32 has properties such as heat resistance and water resistance as well as adhesive strength by using thermosetting resins such as melamine, acrylic, polyester, and the like.

The surface layer 30 may be plywood on the cosmetic layer 20 in two ways as follows.

1. The nanofibers are directly applied to the cosmetic layer 20 through a spinning machine for spinning the nanofibers, and then coated with an impregnated resin through a coating roll and cured.

2. Coating the nanofiber nonwoven fabric 31 having a thickness of 1 to 500 ㎛ with an impregnated resin 32 through a coating roll to make a surface layer 30, then the substrate 10 and the decorative plate 20 is laminated The surface layer 30 is laminated on the upper portion and cured at 100 to 150 ° C. to produce a non-slip flooring material.

EXAMPLE

100 nm thick nanofiber nonwoven fabric 31 made of PAN nanofibers with a diameter of 100 nm was impregnated with melamine resin as an impregnated resin 32 through a coating roll to make a surface layer 30, and then the MDF substrate layer 10 and The surface layer 30 was laminated on the top of which the makeup plate 20 was laminated and cured at 120 ° C., thereby preparing a non-slip floor having a structure as shown in FIG. 1.

[Test Example]

Non-slip properties were evaluated for the flooring material of the examples and comparative examples, and the results are shown in Table 1. In this case, the non-slip property was obtained by measuring the dynamic friction coefficient based on Din 53375. The dynamic friction coefficient represents a friction coefficient (or friction value) in a given friction state, and the larger the friction coefficient, the greater the protection against slippage.
