3 is a schematic view schematically showing a cross-section of an example of a flooring according to another embodiment of the present invention.
The inventors of the present invention have been studying a flooring material to increase the strength of the transparent coating layer contained in the flooring material by applying a transparent film for flooring material containing a certain amount of PVC resin and acrylic resin as a transparent film layer of the flooring material, It has been confirmed that the amount of TVOCs generated in the transparent coating layer itself and the amount of TVOCs generated in the lower portion of the transparent coating layer can be reduced by using a solid-phase thermal stabilizer in the film, thereby completing the present invention.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.
In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.
In the drawings, the thickness is enlarged to clearly represent the layers and regions. In the drawings, for the convenience of explanation, the thicknesses of some layers and regions are exaggerated.
Hereinafter, the formation of any structure in the "upper (or lower)" or the "upper (or lower)" of the substrate means that any structure is formed in contact with the upper surface (or lower surface) of the substrate However, the present invention is not limited to not including other configurations between the substrate and any structure formed on (or under) the substrate.
Conventional flooring has formed a coating layer on the surface of the bottom material to improve the surface strength and improved the surface strength by controlling the thickness of the coating layer. However, in this case, if the thickness of the coating layer is made too thick, the manufacturing cost becomes high, and in the case of the usual PVC coating layer, there is a problem that the amount of TVOCs emitted from the bottom layer or the bottom layer itself is high.
In order to overcome this, the above-mentioned transparent film for flooring is characterized by having high hardness when applied to the top of the bottom material, thereby giving excellent surface strength and scratch resistance to the flooring material and reducing the amount of TVOCs emission.
The present invention provides a transparent film for flooring comprising a polyvinyl chloride resin, an acrylic resin and a solid-phase heat stabilizer.
The polyvinyl chloride resin is a polymer obtained by polymerization of vinyl chloride. The polymer has a specific gravity of 1.45 and softens at 65 to 85 캜, and plasticity occurs at 120 to 150 캜, and dissolves at 170 캜 or higher. It has excellent acid resistance and alkali resistance and is non-toxic and flame retardant. Also, it has good electrical insulation and is insoluble in alcohols, organic acids and aliphatic hydrocarbons. It swells in aromatic hydrocarbons such as benzene and toluene, and dissolves well in ketones such as cyclohexanone, methyl isobutyl ketone, nitrobenzene and the like. Decomposition occurs when hydrochloric acid is dropped during heating, but decomposition becomes violent when the temperature exceeds 190 ° C.
The acrylic resin is a polymer from an ester such as acrylic acid or methacrylic acid, and may be a polymer such as polymethyl methacrylate (PMMA), polyethyl methacrylate (PEMA), poly (methyl acrylate), poly (ethyl acrylate) And combinations thereof. However, the present invention is not limited thereto. In order to process with the PVC resin, it is required to have compatibility with PVC and transparency must be exhibited when mixing, so that the acrylic resin satisfies these properties.
By including the acrylic resin, the transparent film for a floor material itself can realize an excellent hardness, and thus the floor material to which the transparent film for a floor material is applied is excellent in surface hardness and scratch resistance. In addition, the transparent film for flooring including the acrylic resin has a function to block various TVOCs coming from the bottom of the floor by being included in the upper part of the flooring.
Specifically, the acrylic resin may be a polymethyl methacrylate (PMMA) resin. Since the transparent film for flooring of the present invention includes the above polymethylmethacrylate resin, it is superior in weatherability and transparency and high hardness because it is excellent in compatibility with PVC than other acrylic resins. The transparent film for flooring containing PMMA as an acrylic resin can have both excellent workability and an effect of improving the scratch resistance, thereby achieving economical effect and surface strength improvement at the same time. Further, when the transparent film for flooring containing PMMA is applied to the upper part of the bottom material, the blocking performance of TVOCs coming from the bottom of the bottom material is better.
The acrylic resin may be included in an amount of about 0.1 part by weight to about 50 parts by weight, preferably about 5 parts by weight to about 20 parts by weight, more preferably about 10 to about 20 parts by weight, based on 100 parts by weight of the polyvinyl chloride resin 17 parts by weight. When the acrylic resin is contained in an amount less than about 0.1 part by weight, the proportion of the polyvinyl chloride resin is increased, so that the hardness of the transparent film becomes too low to deteriorate the physical properties. When the acrylic resin is contained in an amount exceeding about 50 parts by weight, And the workability may be lowered.
The weight average molecular weight (Mw) of the acrylic resin may be about 50,000 g / mol to about 150,000 g / mol, and specifically about 80,000 g / mol to about 130,000 g / mol. By having the weight average molecular weight in the above range, when the transparent film is processed by, for example, extrusion molding, car rendering or blow molding, excellent workability is realized, It is possible to prevent the phenomenon of sticking to the apparatus, thereby further reducing the raw material loss rate. If the molecular weight is out of the range, the acrylic resin may not melt at the processing temperature of PVC, which is an undesirable problem.
The glass transition temperature of the acrylic resin may be 85 캜 to about 115 캜. By having the glass transition temperature within the above range, the workability of the transparent film layer can be appropriately adjusted together with the polyvinyl chloride resin.
The melt index of the acrylic resin may be from about 10 g / 10 min to about 25 g / 10 min at 230 캜 and 3.8 kg according to the conditions of ASTM D1238, and specifically about 15 g / 10 min to about 25 g / 10 min Lt; / RTI > This is a numerical value greater than that of general PMMA. By having a melt index within the above range, the acrylic resin can have appropriate flexibility, and when the transparent film containing the acrylic resin is applied to a flooring, excellent workability is realized, When the transparent film is mixed with the vinyl resin, the transparency film is not too soft and hardness can be realized.
In addition, the present invention includes a solid-phase heat stabilizer. Specifically, the heat stabilizer plays a role of preventing degradation of original characteristics due to decomposition and aging of the thermoplastic resin due to oxygen, light, heat energy, . The conventional transparent film for flooring has a problem that TVOCs are generated in a transparent film due to a solvent or a solvent for making a liquid phase by using a liquid heat stabilizer. Therefore, the present invention has the effect of reducing the amount of TVOCs generated in the transparent film for flooring itself by using a solid-phase heat stabilizer in the form of powder or the like.
Specifically, the solid phase heat stabilizer may include 0.1 to 10 parts by weight, preferably 2 to 8 parts by weight, based on 100 parts by weight of the polyvinyl chloride resin. When the above range is satisfied, an excellent effect of viscosity stability and thermal stability of the transparent film can be realized.
The solid phase heat stabilizer may be at least one selected from the group consisting of Cd / Ba / Zn based, Cd / Ba based, Ba / Zn based, Ca / Zn based, Na / Zn based, Sn based, Pb based, , But the present invention is not limited thereto. It is preferable to use a Ba / Zn system as a solid phase heat stabilizer because the Ba / Zn system stabilizer is suitable for a soft calender film because of its good transparency and thermal stability.
The transparent film may further include at least one selected from the group consisting of plasticizers, lubricants, processing aids, and combinations thereof.
As the plasticizer, eco-friendliness can be achieved by using, for example, a benzoate-based, citrate-based, phosphate-based plasticizer and the like. The plasticizer may be included in an amount of about 20 parts by weight or less. Accordingly, the bleeding phenomenon of the plasticizer can be further suppressed, and compatibility with other components can be maintained at a good level, thereby realizing desired properties easily.
The type of the lubricant is not particularly limited, but it can be eco-friendly including an environmentally friendly higher fatty acid. Specifically, stearic acid which is a saturated higher fatty acid having 18 carbon atoms can be used. In addition, the lubricant may be contained in an amount of about 3 parts by weight or less, thereby effectively preventing the resin from adhering to the calender roll or the press during processing such as car rendering or pressing to form the transparent film.
The transparent film may further include other additives, and the other additives may be various kinds of materials well known in the art and are not particularly limited.
Further, the thickness of the transparent film may be about 0.05 mm to about 1.5 mm, and preferably about 0.07 mm to about 0.75 mm. It is possible to appropriately block the TVOCs coming from the bottom material including the transparent film on the upper side and to protect the printing of the printing layer laminated below the transparent film layer without increasing the thickness of the transparent film excessively, And at the same time, high rigidity is imparted, and excellent surface hardness and scratch resistance can be realized.
(A) preparing a mixed composition by stirring a polyvinyl chloride resin, an acrylic resin, and a solid phase heat stabilizer; And (b) applying heat to the composition and applying a calendar device; The present invention also provides a method for manufacturing a transparent film for a flooring comprising the steps of:
Also, in the step (a), the composition may further include at least one selected from the group consisting of a plasticizer, a lubricant, a processing aid, and a combination thereof so that the excellent hardness of the flooring material and the reduced amount of TVOCs A transparent film can be produced.
In the step (a), the stirring may be performed at a speed of from about 10 rpm to about 100 rpm, and more specifically, from about 50 rpm to about 70 rpm. In order to prepare the above composition, the solid state heat stabilizer should be mixed with the polyvinyl chloride resin and the acrylic resin so that the solubility may be lower than that of the liquid phase heat stabilizer. However, by mixing at the stirring speed of the above range, And the like.
In the step (b), heat can be applied to the composition at a temperature of about 130 ° C to about 200 ° C, specifically, about 150 ° C to about 180 ° C. By the heat treatment at the temperature within the above range, the solid phase stabilizer, the polyvinyl chloride resin and the acrylic resin can be easily mixed without impairing the basic physical properties of the transparent film for flooring and the function of other components.
The present invention provides a flooring comprising a transparent film layer formed of a transparent film for a flooring according to the above. By including the transparent film layer, the bottom material realizes high strength properties such as surface hardness and scratch resistance, and can reduce the amount of TVOCs generated.
In addition, the bottom material may further include at least one layer selected from the group consisting of a surface treatment layer, a print layer, a dimensionally stable layer, a white layer, a base layer, a balance layer, and combinations thereof.
Specifically, the base layer may be a fiber-reinforced base layer. A cross section of the flooring comprising the fiber-reinforced base layer is schematically shown in Fig.
The fiber reinforcing agent used in the fiber reinforcing base layer may be selected from the group consisting of inorganic materials such as glass fiber, organic materials such as aramid fiber, nylon and polyester, natural materials such as wood fiber, and combinations thereof.
For example, the bottom layer may comprise a transparent film layer / print layer / white layer / base layer; Or a surface treatment layer / a transparent film layer / a print layer / a white layer / a base layer; Or transparent film layer / print layer / white layer / base layer / balance layer; Or a surface treatment layer / a transparent film layer / a print layer / a white layer / a base layer / a balance layer; Or a surface treatment layer / a transparent film layer / a print layer / a white layer / a base layer / a dimensionally stable layer / a base layer / a balance layer; Or a surface treatment layer / a transparent film layer / a printing layer / a white layer / a fiber reinforcing base layer / a balance layer; May comprise a stacked structure of layers.
The surface treatment layer, the transparent film layer, the print layer, the white layer, the base layer, the dimensionally stable layer and the balance layer may further comprise a plasticizer, a melt strength enhancer, a lubricant and the like. And the content thereof can be appropriately adjusted, and is not particularly limited.
The surface treatment layer can improve the stain resistance of the bottom material to facilitate cleaning. For example, a general UV curable composition such as a urethane acrylate UV curable composition is applied on a transparent film layer and irradiated with ultraviolet light But it is not limited thereto. The surface treatment layer may be from about 0.01 mm to about 0.1 mm, but is not limited thereto.
The transparent film layer is a transparent film layer for a bottom material of the present invention, as described above.
The printing layer may be formed by imparting a pattern to the surface of the white layer stacked on the bottom in various ways such as transfer printing, gravure printing, screen printing, offset printing, rotary printing, or flexographic printing, . Such a printing layer may have a thickness of, for example, from about 0.01 mm to about 0.3 mm, and may be difficult to print when formed to a thickness of less than about 0.01 mm, There is a problem that the manufacturing cost is increased.
The white layer is a layer having a white color. The pattern and the pattern of the printing layer can be clearly displayed, and the adhesion between the printing layer stacked on the upper side and the base layer stacked on the lower side can be improved, and excellent durability can be realized.
The base layer supports the upper transparent layer and the print layer as the most basic layer of the bottom layer, and absorbs impacts of the upper and lower layers. Such a base layer may have a thickness of, for example, from about 1.0 mm to about 5.0 mm, and if the thickness of the base layer is about 1.0 mm or less, the above function can not be performed properly. If it is exceeded, it will cause an increase in the cost of manufacturing the flooring.
The balance layer is a portion where adhesion to the floor surface is made during construction. The balance layer protects the back surface opposite to the surface of the flooring material. The balance layer serves to protect the floor from moisture and has a thickness of about 0.10 mm to about 2.0 mm. It is not limited.
The white layer, the base layer, the balance layer or all of them may be selected from the group consisting of titanium dioxide, calcium carbonate, wood powder, Mica, glass fiber, starch, natural fiber, rice husk, And a combination thereof.
The dimensionally stable layer can impart dimensional stability to the temperature change. The dimensionally stable layer may comprise a glass fiber. More specifically, the present invention relates to a method for producing a laminated sheet, which comprises preparing a sheet by mixing glass fibers and pulp in an appropriate amount with a binder, impregnating the sheet with a vinyl chloride sol (sol) have.
The flooring can be produced by, for example, extrusion molding, car-rendering, or blow molding to produce the respective layers in the form of films or sheets, and then applying heat and pressure thereto using a plywood process or the like known in the art, But is not limited thereto.
The flooring may be, for example, a floor sheet or a floor tile, and may in particular be a floor tile.
The bottom sheet is relatively flexible and more important than the durability to prevent whitening, but the bottom tile is relatively inflexible and may have more durability than prevention of whitening.
Hereinafter, preferred embodiments of the present invention will be described. It is to be understood, however, that the same is by way of illustration and example only and is not to be construed in a limiting sense. The contents not described here are sufficiently technically inferior to those skilled in the art, and a description thereof will be omitted.

Except that 27 parts by weight of a polyhydroxyalkanoate (PHA) resin was used instead of polymethyl methacrylate (PMMA) resin in 100 parts by weight of the polyvinyl chloride resin in the production of the transparent film layer. 1).
Comparative Example 4
Except that a polymethylmethacrylate (PMMA) resin was not contained at all in the production of the transparent film layer and 2 parts by weight of a liquid stabilizer was used instead of the Ba / Zn-based powder stabilizer in 100 parts by weight of the polyvinyl chloride resin A flooring material was prepared in the same manner as in Example 1.
(
Experimental Example
)
TVOCs (mg / m 2 .h), film hardness (shore hardness D), and the like were measured after the flooring materials of Examples and Comparative Examples were cut to a size of 20 mm x 20 mm x 3 mm (width x width x thickness) , Film abrasion strength and scratch resistance were measured according to the following methods, and the results are shown in Table 1.
1. TVOCs emission measurement
The content of TVOCs was measured by Small Chamber method.
2. Film hardness measurement
Film hardness was measured using a rubber hardness shore D.
3. Measurement of Film Wear Strength
The film abrasion strength was measured by using Abrasive Description (Medium-Coarse) (manufactured by Taber) with the abrasion wheel H-18.
4. Measurement of scratch resistance
Scratch resistance of the film was measured by using a 0.5 mm Tip of Erichsen Scratch Tester (ISO 4586-2 / DIN EN 438-2) to measure the force of film scratching.
- Number of times the film is worn
As shown in Table 1, it was confirmed that TVOCs generated in Examples 1 to 3 were significantly lower in the amount of generated TVOCs (less than 0.1 mg / m 2 · h) and superior in surface strength, compared with Comparative Examples 1 to 4. On the other hand, in the case of Comparative Examples 1 and 2 including the liquid phase heat stabilizer, it can be seen that the amount of TVOCs generated is higher than those in the examples including the solid phase heat stabilizer. In particular, in the case of Comparative Example 2, it was confirmed that the film hardness and scratch resistance were equal to or higher than those of Examples, but the film abrasion strength was more harsh. In Comparative Examples 3 and 4 which contain PHA instead of PMMA or no PMMA at all, it was confirmed that the effect of blocking TVOCs is small and the strength of the film is also lowered. In the case of the flooring material to which the transparent film for flooring according to the present invention is applied, It can be seen that the blocking effect is great and excellent strength is realized.
