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 cushioning bottom material of the first embodiment of the present invention includes a

The
In the present invention, the
The acrylic elastic resin may be a copolymer of a polymer of an alkyl methacrylate monomer constituting a hard segment and a polymer of an alkyl acrylate monomer constituting a soft segment. Here, the copolymer may be a core-shell structure copolymer or a block copolymer.
The copolymer of the core-shell structure has a structure in which a soft segment is used as a core and a hard segment is used as a shell for enclosing the core.
As a method of producing the copolymer of the core shell structure, a core including a soft segment is manufactured, and then a shell including a hard segment and surrounding the core is manufactured. The core and the shell may be prepared by emulsion polymerization or suspension, but it is preferable to use suspension polymerization which facilitates separation and processing of the polymer.
The block copolymer is preferably composed of a soft segment and a hard segment, and preferably a triblock copolymer in which a hard segment is bonded to both ends of the soft segment, because it can improve low temperature impact resistance, heat resistance and the like. As a method of producing the block copolymer, a method of living polymerization of monomers constituting each block is used. Such living polymerization can be carried out, for example, by a method in which an organic alkali metal compound is used as a polymerization initiator and anionic polymerization is carried out in the presence of a mineral acid such as a salt of an alkali metal or an alkaline earth metal, a method in which an organic alkali metal compound is used as a polymerization initiator, , A method of polymerizing an organic rare earth metal complex as a polymerization initiator, a method of radical polymerization using an? -Halogenated ester compound as an initiator in the presence of a copper compound, and the like. Alternatively, a method of polymerizing the monomers constituting each block by using a polyvalent radical polymerization initiator or a polyvalent radical chain transfer agent to prepare a mixture containing the block copolymer, and the like. It is preferable that the block copolymer does not contain an oligomer which can be obtained in a high purity and has a narrow molecular weight distribution, that is, a low molecular weight substance which is a factor for lowering impact resistance and heat resistance or a factor for lowering fluidity, A method in which an organic alkali metal compound is used as a polymerization initiator and an anionic polymerization is carried out in the presence of an organoaluminum compound is preferred. Representative examples of the organoaluminum compound include isobutylbis (2,6-di-t-butyl-4-methylphenoxy) aluminum, isobutylbis (2,6- Bis (2,6-di-t-butyl-4-methylphenoxy) aluminum, n-octylbis Octylbis [2,2'-methylenebis (4-methyl-6-t-butylphenoxy)] aluminum, tris (2,6-di- Di-t-butyl-4-methylphenoxy) aluminum, tris (2,6-diphenylphenoxy) aluminum and the like. Among these, isobutyl bis (2,6-di-t-butyl-4-methylphenoxy) aluminum, isobutyl bis (2,4- Di-t-butyl-4-methylphenoxy) aluminum or n-octylbis (2,4-di-t-butylphenoxy) aluminum is particularly preferable in view of polymerization activity, block efficiency and the like.
Here, it is preferable that the above-mentioned copolymer has a hard segment: soft segment in a ratio of 20 to 40: 80 to 60% by weight, preferably 25: 35: 75 to 65% Mechanical properties suitable for use as a raw material for the flooring, in particular abrasion resistance can be imparted.
The hard segment preferably has a glass transition temperature in the range of 80 to 120 占 폚 and the soft segment may preferably have a glass transition temperature in the range of -60 to -20 占 폚.
Examples of the alkyl methacrylate monomer constituting the hard segment include methyl methacrylate, ethyl methacrylate, n-propyl methacrylate, i-propyl methacrylate, n-butyl methacrylate, Acrylates such as methyl methacrylate, ethyl methacrylate, butyl methacrylate, butyl methacrylate, hexyl methacrylate, 2-ethylhexyl methacrylate, heptyl methacrylate, octyl methacrylate, cyclopentyl methacrylate, 3-vinylcyclohexyl methacrylate, cyclohexyl methacrylate , And preferably at least one selected from the group consisting of methyl methacrylate.
The alkyl acrylate monomers constituting the soft segment may be selected from the group consisting of methyl acrylate, ethyl acrylate, n-propyl acrylate, i-propyl acrylate, n-butyl acrylate, t-butyl acrylate, pentyl acrylate, hexyl Acrylate, 2-ethylhexyl acrylate, heptyl acrylate, octyl acrylate, cyclopentyl acrylate, 3-vinyl cyclohexyl acrylate, and cyclohexyl acrylate, and preferably at least one selected from the group consisting of n-butyl acrylate.
The acrylic elastic resin does not contain low molecular weight substances such as residual monomers and oligomers, and does not contain a plasticizer. Also, it has a low melt viscosity, high fluidity, low viscosity of solution, low emission of volatile organic compounds, and excellent weatherability. In addition, compatibility with the polar resin and adhesiveness are good, and when the synthetic resin layer such as PVC is selectively placed in the lower part, the adhesive strength is excellent.
The cushioning flooring according to the present invention uses the acrylic elastic resin as the
The
The
Preferably, in the case of calender molding, the content of additives such as additives can be freely controlled as compared with other production methods, and thus a flooring material having excellent flexibility, impact resistance, mechanical strength, workability, It is possible to further reduce the cost of the raw material, and therefore, it is preferable to produce it by the calender molding method.
The
The transparent elastic layer is based on the fact that the acrylic elastic resin is a resin that can be processed into a transparent state. By using such a transparent elastic layer, And the like. In addition, the
2, the cushioning bottom material of the second embodiment of the present invention includes a
The construction of the
The elastic layer 70 'includes a composite resin including an acrylic elastic resin and a poly (lactic acid). The mixing ratio (weight ratio) of the acrylic elastic resin to the poly (lactic acid) is 100: 1-1: 100. Preferably, the mixing ratio (weight ratio) of the acrylic elastic resin to the poly (lactic acid) may be 95: 5 - 30: 70, and more preferably 90: 10 - 40: 60.
When the elastic layer is composed of only poly (lactic acid), there may be some disadvantages as follows.
First, the poly (lactic acid) is poor in dimensional stability, so that deformation such as shrinkage and warping may occur severely, and the physical properties of the floor material containing the poly (lactic acid) may become inadequate.
Secondly, poly (lactic acid) is easily blocked under high temperature conditions such as during the summer season, so that the films do not stick to each other when they are wound, and therefore, productivity can be lowered in producing floor materials by using them.
Third, the poly (lactic acid) has a narrow processing temperature range (130 to 150 ° C) and has low processability. Therefore, productivity can be lowered when the floor material is produced using the poly (lactic acid).
Fourth, polylactic acid is difficult to apply to flooring materials with a narrow temperature range (20 to 35 ° C), and tends to be excessively hardened when the temperature is out of the above range, that is, below 20 ° C. It tends to lose its elasticity at 35 DEG C or higher and become excessively softened. Thus, the physical properties required as a flooring material are rapidly lowered, and the function as a flooring material can be lost.
Therefore, the elastic layer 70 'used in the present invention preferably has a mixing ratio (weight ratio) of the acrylic elastic resin and poly (lactic acid) of 100: 1-1: 100, preferably 95: 5 - 30: 70, : 10 - 40: 60, which is characterized by imparting elasticity, flexibility and soundness compared to the case where polylactic acid is used alone. An elastic layer having excellent elasticity, flexibility and sound insulation within the above-mentioned range of use and particularly useful for the production of flooring can be obtained.
When the content of the acrylic elastic resin is less than the above range, there is a problem in that the above-mentioned polylactic acid is used as a bottom material, that is, a problem of low dimensional stability, high temperature blocking, a narrow processing temperature range, It is not preferable because it may not be sufficient to solve.
In the present invention, the elastic layer 70 'includes a composite resin including an acrylic elastic resin and poly (lactic acid), thereby imparting elasticity, flexibility and soundness to the surface layer of the bottom material, Thereby preventing the user from being exposed to harmful substances even when the surface layer is exposed.
The cushioning bottom material of the second embodiment of the present invention is the same as that described in the cushioning bottom material of the first embodiment except that acrylic elastic resin and polylactic acid-containing composite resin are used as the elastic layer 70 ' It is omitted. That is, the type and properties of the acrylic elastic resin and the method of forming the elastic layer 70 'are the same as those of the cushioning floor material of the first embodiment.
The cushioning flooring material of the present invention includes an acrylic elastic resin and a composite resin including polylactic acid as described above as the elastic layer 70 ', which is excellent in elasticity, flexibility and sound insulation, and has a soft touching effect.
