Meanwhile, the finishing material layer may further include a thickener, a silane modifier, an emulsifier, and an emulsion stabilizer, and may further include additives if necessary.

The thickener is added to increase the viscosity of the finishing material layer to improve emulsion stability, prevent precipitation of particulate matter, and improve workability. As the thickener, various commonly used thickeners such as alginic acid, xanthan gum, carbomer, acrylate-based thickener, and polyester-based thickener may be used. For example, CARBOPOL SF1, a commercially available cross-linked acrylic polymer, and RM-825 or NLS-210, a hydrophobically modified polyacetal polyester, may be used as the thickener, but are not limited thereto.

The thickener may be included in an amount of 1 to 7 parts by weight based on 100 parts by weight of the finishing material layer composition, and when it is included in an amount of less than 1 part by weight, the viscosity of the finishing material layer is excessively low, resulting in a decrease in emulsion stability in the finishing material layer or Problems such as sedimentation may occur, and if it is included in more than 7 parts by weight, the viscosity of the finishing material layer may excessively increase and workability may be deteriorated, so it is preferably included within the above-described weight range.

The silane modifier silane-modifies the epoxy resin, and then mixes the finishing material layer composition and the curing agent to reinforce the structure of the polymer network formed when the polymer reaction is performed, and forms a network between the organic polymer material and the inorganic mixed powder. By doing so, a more dense network structure is formed and the adhesion of the flooring composition is improved.

As the silane modifier is added, the adhesion compatibility of the film flooring material is improved, so that strong adhesion is formed even when the surface of the coated film is an inorganic material such as cement, and an additional film is easily formed on the film formed by applying the film flooring material of the present invention. can do.

Examples of the silane modifier include fluoro trimethoxy silane, methyl triacetoxy silane, amino propyl trimethoxy silane, amino propyl triethoxy silane, fluoro propyl triethoxy silane, amino propyl methyl dimethoxy silane, β( Aminoethyl)-γ-amino propyl trimethoxy silane, γ-mercapto propyl trimethoxy silane, β-(aminoethyl)-γ-amino propyl methyldimethoxy silane and glycidoxy propyl triethoxy silane may be used. It may be, but is not limited thereto.

The silane modifier may be included in an amount of 0.01 to 0.25 parts by weight based on 100 parts by weight of the finishing material layer composition. If it is included in less than 0.01 part by weight, the above-mentioned effect is insignificant, and if it is included in more than 0.25 parts by weight, before mixing with the curing agent. Since problems such as gelation or hardening of the finishing material layer itself or poor long-term storage stability occur, it is preferable to add it within the above-mentioned weight range.

The emulsifier is a component added to uniformly disperse the oily components included in the finishing material layer into the solvent, water. As the emulsifier is added, the oily components form micelles and are uniformly dispersed in the solvent. The micellar structure thus formed can be maintained in a uniformly dispersed state by a thickener and an emulsion stabilizer.

As the emulsifier, various emulsifiers such as cationic emulsifiers, anionic emulsifiers, nonionic emulsifiers, and amphoteric emulsifiers may be used, and anionic emulsifiers may be preferably used for more stable micelle formation and maintenance of the composite resin composition, and more preferably Anionic emulsifiers and nonionic emulsifiers may be used together.

Anionic emulsifiers include sodium linear alkyl benzene sulfonate, sodium dodecyl benzene sulfonate, methyl propyne sulfonate, alkyl benzene sulfonate, alkyl amide sulfonate, olefin sulfonate, propyl naphthalene sulfonate, lignin sulfonate, melamine At least one or more anionic emulsifiers selected from the group consisting of sulfonic acid salts, sodium salt sulfonic acid salts, and lithium salt sulfonic acid salts may be used, but are not limited thereto.

Nonionic emulsifiers include esters of sorbitan and fatty acids, esters of pentaerythritol and fatty acids, monoesters of propylene glycol and fatty acids, monoesters of glycerin and fatty acids, polyethylene glycol esters of sorbitan and fatty acids, and polyethylene glycol. ester type emulsifiers such as esters of sorbitol and fatty acids and esters of polyethylene glycol and fatty acids; ether-based emulsifiers such as polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, and alkyl polyglycoside; fatty acid amide-based emulsifiers such as fatty acid dialkanolamides, fatty acid monoalkanolamides, and polyoxyethylene fatty acid amides; and fatty amine derivative emulsifiers such as polyoxyethylene alkylamines; etc. may be used, and as commercial nonionic surfactants, Triton X-100, Triton X-45, Nonoxynol-9, Polysorbate 20, Polysorbate 40, Polysorbate 60, Polysorbate 80, etc. may be used, but are not limited thereto. .

The emulsifier may be included in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the finishing material layer composition. If it is included in less than 0.1 part by weight, sufficient emulsification does not occur, and if it exceeds 5 parts by weight, there is no additional emulsifying effect, and an excessive amount of emulsifier Since the physical properties of the flooring coating film may be deteriorated by this, it is preferably included within the above-described weight range.

In particular, when an anionic emulsifier and a nonionic emulsifier are used together to create a stable emulsified state, it is preferable that the anionic emulsifier and the nonionic emulsifier are used in a weight ratio of 1: 1 to 3.

The emulsion stabilizer functions as a protective colloid to protect the micelle particles formed by the emulsifier to maintain their shape and dispersion state. A cellulosic emulsion stabilizer may be used as such an emulsion stabilizer, for example, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, nonoxynyl hydroxyethyl cellulose, cetyl hydroxyethyl cellulose, etc. may be used. It is not limited.

When these cellulose-based emulsion stabilizers are mixed in a powder state, non-uniform mixing may occur, so it is preferable to first disperse them in water to form a solution before using them. In this case, after preparing a 1-10% concentration solution, It is desirable to mix with the ingredients.

The emulsion stabilizer may be included in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the finishing material layer composition.

If the content of the emulsion stabilizer is out of the above weight range and the content is insufficient, the above-mentioned emulsion stabilizing effect is insignificant, and if it is excessively included, gelation proceeds during storage and storage stability is deteriorated. Preferably included within the stomach.

The additive is a component added for purposes such as storage stability of the finishing material layer, workability when mixing with a curing agent and mixed powder to prepare a coating film type flooring material, and improvement of physical properties of a coating film formed by curing the flooring composition. Components such as extender pigments, color pigments, hardness enhancers, curing accelerators, layer separation inhibitors, dispersants, catalysts, antifoaming agents, preservatives, and deodorants may be added.

The additive may be included in an amount of 10 to 80 parts by weight based on 100 parts by weight of the finishing material layer composition. When included, the additive may act as an impurity to degrade the physical properties of the coating film or degrade workability and storage stability of the subject, so it is preferably added within the above-described weight range.
