- the polar group concentration is too low, and adhesion occurs.
- the effect of improving the adhesion to the agent and wax does not appear.
- the MFR is 40 g / 1 Omin or less
- the difference in MFR from other resins decreases, making it difficult to obtain a fine particle dispersion structure. In this case, the crystallization of the resin is too low, which impairs the performance as a floor material such as abrasion resistance.
- the vinyl acetate content is 50% or more and the amount of the ethylene-vinyl acetate copolymer having an MFR of 40 to 100 g / 10 min is less than 25 parts by weight, the high-concentration polar groups dispersed in the entire system are reduced. If it is insufficient, and if it is more than 45 parts by weight, the portion of the resin which has little crystallization will be too large, which will impair the performance as a floor material such as abrasion resistance.
- MFR of polyolefin resin is 20 g / 1 Omin or more
- MFR with other resin Use a polyolefin resin with a high crystallinity and high hardness with an MFR of 20 g / 10 min or less, preferably 10 g / 10 min or less. By doing so, the wear resistance is improved.
- polyethylene is particularly preferred as the polyolefin resin.
- Polyethylene is not particularly limited, but in consideration of the moldability such as a calendar, low-density polyethylene, and more preferably, linear low-density polyethylene is preferable because of good workability.
- the blending amount of the inorganic filler in the flooring material is preferably from 400 to 700 parts by weight, more preferably from 450 to 65 parts by weight.
- the amount of the inorganic filler is less than 400 parts by weight, the resin content is too large, rigidity is insufficient as a floor material having a single-layer structure, and there are problems in physical properties such as an increase in residual dents. But it is very expensive compared to PVC flooring. If the amount is more than 700 parts by weight, workability is extremely deteriorated.

Further, the flame retardancy is improved.
- various fillers known as fillers for flooring such as calcium carbonate, magnesium carbonate, talc, silica, clay, glass fiber, and synthetic natural fiber can be used. Calcium carbonate powders having the following average particle size are preferred. Further, when aluminum hydroxide powder is blended with calcium carbonate powder, a flooring material having high flame retardancy can be obtained.

- MMA methyl methacrylate
- acrylate a copolymer of methyl methacrylate
- MMA methyl methacrylate
- acrylate an acrylate
- the homopolymer of MMA only that is, polymethyl methacrylate is a hard resin, and if polymethyl methacrylate is used, it becomes a hard and brittle floor material with poor workability.
- a resin obtained by copolymerizing MMA and acrylate a certain degree of flexibility was obtained, and a floor material with good workability was obtained.
- workability such as kneading is also improved. It is considered that the copolymerization of acrylic acid ester with MMA has a lower melting point than methyl methyl acrylate.
- the copolymer of MMA and an acrylic ester also has a polar group in the molecular structure, even when blended with the flooring material of the present invention, the adhesiveness of the adhesive and the wax is maintained.

- the reasons are as follows: (1) ethylene-acrylic acid ester-maleic anhydride terpolymer has good compatibility with other resin components; (2) ethylene-acrylic acid ester-maleic anhydride terpolymer.
- maleic anhydride adheres very well to the inorganic filler, it is conceivable that the resin component and the inorganic filler are strongly bonded.
- the flooring material of the present invention further comprises 1 to 30 parts by weight, more preferably 15 to 25 parts by weight, of an evening squirrel such as petroleum resin or rosin, thereby further adhering to an adhesive or wax. The performance is improved.
- the specific polyolefin flooring material of the present invention which has sufficiently improved adhesiveness and adhesiveness for the above-mentioned reasons, is used for the specific polyolefin flooring material of the present invention.
- the performance as a flooring material is further enhanced only when the above amount is blended, and sufficient adhesion with adhesives and wax can be obtained only by blending the traditional wood flooring material with the evening sun. Can not do.
- resin-based flooring additives such as pigments, cross-linking agents, antioxidants, lubricants, processing aids, and light stabilizers are added to the flooring material of the present invention as necessary. Can do things.
- the flooring material of the present invention has a single-layer structure of the same composition, and is particularly preferably formed in a tile shape.
- it can be applied as a square tile flooring having a side of about 30 to 60 cm.
- a pattern material added to it with a ⁇ pattern, or a multi-color pulverized chip laminated and molded by calender or press I do not care.
- the thickness of the floor material having a single-layer structure is not particularly limited, but a thickness of about 2 to 4 mm is preferable.
- the floor material having a single-layer structure as described above can be manufactured by the examples described below.
- an ethylene monoacetate copolymer having a vinyl acetate content of 50% or more and an MFR of 40 to 100 is 25 to 45 ffi parts, and a polyethylene having an MFR of 1 to 20 is 55 to 50 parts.
- the mixture is melt-kneaded with a hand-balance mixer or a pressure kneader, sheeted to a predetermined thickness with a mixing roll and calender rolls, cooled, and then cooled. Punch to the desired dimensions to obtain the desired floor material.
- the flooring material thus obtained is tightly adhered to flooring adhesives and flooring waxes that are currently generally used, as will be described later.
- performance such as abrasion resistance, dimensional stability due to heating, and residual dent ratio has been improved compared to conventional PVC flooring.
- this resin with low crystallization also acts as a plasticizer because it contains an ethylene-vinyl acetate copolymer with a vinyl acetate content of 50% or more and an MFR of 40 to 100 g / 10 min.
- the flooring material is given an appropriate degree of flexibility, becomes familiar with the groundwork, and has very good workability.
- the baseboard containing 55 to 90 parts by weight of the polyolefin resin of the min is a compound other than the above, especially when the vinyl acetate content is 50% or more and the MFR is Compared to a polyolefin-based baseboard that does not contain 10 to 45 parts by weight of an ethylene vinyl monoxide copolymer of 40 to 100 g / 10 min, the adhesive strength of the conventional baseboard adhesive is remarkably superior. Excellent in bending whitening.
- the vinyl acetate content of the ethylene-vinyl acetate copolymer with a vinyl acetate content of 50% or more and an MFR of 40 to 100 g / 10 min becomes 50% or less, the polar group concentration is too low, and adhesion occurs. The effect of improving the adhesiveness with the agent does not appear.
- the MFR is 40 g / 1 Omin or less, the difference in MFR from other resins is reduced, making it difficult to obtain a fine particle dispersion structure. If lOO g / 10 min or more, resin crystallization Is too low, and the molded product becomes sticky.
- the content of vinyl vinyl sulphate is 50% or more and the ethylene-vinyl acetate copolymer having an MFR of 40 to 100 g / 10 min is less than 10 parts by weight, the high-concentration polar groups dispersed in the entire system are reduced. If the amount is insufficient, and if the amount is more than 45 parts by weight, the portion of the resin which has little crystallization will be too large, and the molded product will have a sticky feeling.
- the amount of the inorganic filler in the baseboard is from 150 to 400 parts by weight, more preferably from 200 to 300 parts by weight. Flame retardancy is reduced when the inorganic filler content is less than 150 parts by weight. If the content is more than 400 parts by weight, the baseboard becomes brittle, and the whitening property of bending is deteriorated.
- various known fillers used in conventional building materials such as calcium carbonate, magnesium carbonate, talc, silica, clay, glass fiber, and synthetic natural fiber can be used. Calcium carbonate powder having an average particle size of not more than 100 ⁇ m is preferred. Furthermore, when aluminum hydroxide powder is blended with calcium carbonate powder, a baseboard having high flame retardancy can be obtained.
- the ethylene-maleic anhydride copolymer or the ethylene-methacrylic acid copolymer is further blended in an amount of 1 to 30 parts by weight, whereby the folding whitening property as a baseboard is remarkably improved.
- stiffness is obtained in a sheet in a molten state at the time of production, and productivity is also improved.
- ethylene-maleic anhydride copolymer or ethylene-methacrylic acid copolymer has good compatibility with other resin components; (2) maleic anhydride in the ethylene-maleic anhydride copolymer; Since the methacrylic acid in the ethylene-methacrylic acid copolymer adheres very well to the inorganic filler, it is considered that the resin component and the inorganic filler are strongly bonded.
- the ethylene-maleic anhydride copolymer or the ethylene-methacrylic acid copolymer is blended in an amount of 30 parts by weight or more, no improvement in the physical properties within the above range is observed. Since the above effects are not exerted in a blending amount of not more than 10 parts by weight, the amount of 10 to 30 parts by weight is optimal. More preferably, it is 10 to 20 parts by weight.
- the adhesion to the adhesive is further improved. If the compounding amount is more than 30 parts by weight, the hue becomes unstable and the whitening property is adversely affected. When the amount is less than 1 part by weight, the effect of improving the adhesiveness is not exhibited, so the above amount is optimal. More preferably, it is 10 to 20 parts by weight.
- the tackifier is added to the specific resin baseboard of the present invention, which has sufficiently improved adhesion to the adhesive for the above-mentioned reason.
- the performance as a baseboard is further enhanced only when it is blended in an amount, and sufficient adhesion with an adhesive cannot be obtained only by blending Yuzuki Firer with a conventional baseboard.
- various additives known as resin-based baseboard additives such as pigments, crosslinking agents, antioxidants, lubricants, and light stabilizers, may be added to the baseboard of the present invention as necessary.
- an ionomer resin can be laminated on the surface layer, whereby very high scratch resistance can be obtained, and bending whitening can be prevented more effectively.
- the reason for this is that the ionomer resin is very tough, has a high surface hardness, and has moderate elasticity and flexibility.
- Ionoma resin since Ionoma resin has excellent heat sealing properties, it has good workability not only in co-extrusion but also when applied as a film.
- the baseboard laminated with a nylon resin on the surface also has a very high degree of scratch resistance, and also effectively prevents bending whitening.
- nylon resin is very tough, has high surface hardness, and has moderate elasticity and flexibility.
- the surface layer of the ionomer resin or the nylon resin may be transparent, or various fillers, pigments and the like may be added for coloring and matte. Further, a design can be applied by sandwiching a printing layer between the surface layer and the base layer.
- the baseboard of the present invention is formed in a single-layer or laminated structure, and the thickness is not particularly limited, but is preferably 1 to 3 mm.
- the baseboard of the present invention can be manufactured by the examples described below.
- the surface layer is sheet-molded using another extruder, and then immediately bonded to the above-mentioned sheet to obtain the desired baseboard. Obtainable.
- the skirting board thus obtained is firmly adhered to a currently used skirting board adhesive as shown in the data described below.
- the other physical properties are far superior to those of other polyolefin resin baseboards.
- baseboards laminated with ionomer resin or nylon resin on the surface are highly excellent in scratch resistance and bending whitening.

In this test, tensile adhesion Of note with the strength is the state of the break. When the fracture position is AF (the interface between the adhesive and the flooring material), it indicates that the adhesion between the flooring material and the adhesive is weak. It is desirable that the fracture position is F (the floor material itself) or GA (the interface between the substrate and the adhesive).
- a floor material wax (Stitas, manufactured by Johnson Co.) was applied three times to the surface of the sample, and an X-shaped cut was made in this wax layer. Then, an adhesive tape (Nichiban corrugated cardboard packaging tape) was stuck thereon, sufficiently adhered to the wax layer, the adhesive tape was peeled off at a stretch, and the peeling state of the wax layer on the sample surface was observed.

It can be said that the flooring material does not have the problem of the above, and that it has excellent wear resistance and scratch resistance, and thus has excellent durability.
- Example 7
- the adhesive tensile adhesive strength and the bending whitening property were evaluated by the following methods.
- Adhesive tensile bond strength is measured in accordance with JIS A 5536 (Vinyl floor tiles 'Biel floor sheet adhesive') normal 90 degree peel bond strength test method.
- the adhesives used were vinyl acetate adhesives for vinyl baseboards (Kyoto, Knit One Cement SH, hereinafter referred to as “Adhesive 1”) and vinyl-base emulsion-type adhesives (Tilement EM Habaki, hereinafter referred to as “Adhesive 2”).
- the bending whitening property was measured by the following test method. After curing the baseboard sample for 48 hours in an environment at a temperature of 20 ° C and a humidity of 65%, the baseboard sample is placed on a rod of various diameters with a perfect cross-section in the same environment, and the sample is removed from the baseboard sample. The diameter of the stick that causes whitening of the baseboard sample is used as an index of the bending whitening property of the baseboard sample. For example, when the baseboard sample is wrapped around a 10 mm diameter rod by 180 degrees, and the baseboard sample is whitened, the bending whitening property of the baseboard sample is 1 OR. In this test, the smaller the value, the better the bending whitening property.
- Example 7 To the blend of Example 7, 10 parts by weight of the modified polyethylene used in Example 4 was further blended, and in the same manner as in Example 7, a baseboard sample of Example 8 was produced.
- Example 7 10 parts by weight of Takifair (available from Mitsui Chemicals, Inc., Hiletz T300, hereinafter referred to as Tatsufiya-1j) was added in a proportion of 10 parts by weight. In this way, a baseboard sample of Example 9 was produced.
