1 is a process chart of the coating film flooring construction method using the hydrophilic PVA-based microfiber of the present invention.

Hereinafter, an embodiment of the present invention for implementing such an object will be described in detail.

First, in order to construct a non-slip bottom using the coating film flooring of the present invention, first, the coating film flooring is prepared. As the composition of the coating film, a powder composition and a liquid composition are respectively formed and then mixed.

Therefore, the composition according to the construction method of the present invention, a cement composition, gypsum, siliceous waterproofing agent, fluidizing agent, curing accelerator, aggregate, coloring agent, a powder composition consisting of hydrophilic PVA-based microfibers;

It forms a liquid composition consisting of PURE acrylic emulsion, SB LATEX (Styrene-Butadiene LATEX), antifoaming agent, wetting agent, and water.

Provided are a coating method using a coating material flooring material using a superhydrophilic PVA-based microfiber composed by mixing a powder composition and a liquid composition prepared as described above, and a flooring material for the purpose of preventing slipping.

In the cement composition constituting the powder composition used as the coating film flooring material of the present invention, the cement for shortening the initial strength and the curing time has a specific surface area of white cement, ordinary portland cement, mixed cement such as superhard cement or white cement of 5,300 cm 2. use / g or more of cement powder, Al ₂ O ₃ content of 50 weight% or more of alumina cement, Al ₂ O ₃ content of 35 weight% or more O 1 a special cement such as cement wingye or two or more kinds.

Such cement-based compositions are formulated to contain various ratios within the range of 28 to 39 weight percent of the powder composition to increase initial compressive strength, flexural strength, adhesive strength, and shorten the curing time.

That is, the specific surface area of the mixed cement or white cement such as white cement, ordinary portland cement, super fast cement, or fine powder cement is 5,300 cm ₂ / g or more of fine powder cement, Al ₂ O ₃ content of 50% or more, Al ₂ O ₃ content of 35% or more It can be used by adjusting the mixing amount in the above-mentioned weight ratio in the Irwin-based cement.

In the present invention, gypsum is used to impart reactivity to the cement composition constituting the powder composition. The types of gypsum include anhydrous gypsum (CaSO 4), hemihydrate gypsum (CaSO 4 · ½ H 2 O), and dihydrate gypsum (CaSO 4 · 2H 2 O). .

In the present invention, using 7 to 12 parts by weight of natural anhydrous gypsum having a content of CaO 45% by weight or less, SO ₃ 46% by weight or more based on the powder composition 100, when less than 7 parts by weight can not impart reactivity to the cement composition In over 12 parts by weight, overexpansion occurs due to excessive reaction.

In the present invention, a siliceous waterproofing agent which is an inorganic waterproofing agent is used. The effect is mixed into the powder composition to densify by filling the pores of the cement hardener chemically and physically to improve the waterproofing. As the type, 1 to 2 kinds of reactive fly ash, silica fume, clay silicate, and non-reactive stone powder are mixed to use 3 to 6 parts by weight in the total weight ratio of the powder composition.

At this time, when using less than 3 parts by weight, the waterproof effect is insignificant, and when more than 6 parts by weight unreacted substances are generated, the physical properties are reduced.

In the present invention, the excessive liquid composition is used due to the increase in viscosity due to the high Al ₂ O ₃ content and specific surface area in the cement composition, which causes a decrease in strength and delay in curing.

In the present invention, in order to solve this problem, one or two types of naphthalene-based, melamine-based, and polycarboxylic acid-based water reducing agents or glidants, which can be effective by using only a small amount, are mixed.

That is, one selected from a reducing agent or fluidizing agent such as naphthalene-based, melamine-based or polycarboxylic acid-based may be used alone, or two or more thereof may be mixed and used.

At this time, in the present invention, using a water reducing agent or a fluidizing agent up to 0.4 to 1.2 parts by weight of the powder composition may exhibit the properties required in the present invention, and if less than 0.4 parts by weight, it is caused by a high Al ₂ O ₃ content and specific surface area. It can not exert the effect of lowering the viscosity, and if it exceeds 1.2 parts by weight, problems such as material separation and bleeding may occur, so that the naphthalene-based, melamine-based, or polycarboxylic acid-based fluidizing agent is within the range of 0.4 to 1.2 parts by weight. It is preferable to use.

In the present invention, the curing accelerator is used to shorten the curing time after mixing between the compositions to open the vehicle early. In particular, when the construction temperature drops significantly, the usage amount should be adjusted.

Types of curing accelerators used in the present invention include inorganic and organic type, and inorganic type CaCl ₂ , Na ₂ CO ₃ , Al (OH) ₃ , NaAlO ₂ These include chlorides, alkali carbonates, alkali aluminates, calcined rock, water glass, and the like. Other cement minerals include glycerin and triethanolamine (TEA).

In the present invention, 0.05 to 0.5% by weight of at least one or more curing accelerators in the inorganic system is used.

Aggregate used in the powder composition of the present invention is abrasion resistance is strong and impurities are removed, and the moisture content affects the production of the powder composition and mixing, it is good to use a dry aggregate fine grain and granular management well.

Slag series such as converter slag, steel slag, wind slag, stainless steel slag, blast furnace slag, etc. currently used in such safety facilities, and gold steel, recycled garnet aggregate, artificial silica sand, river sand, bauxite One or two or more of these lamps were used, and the size of the aggregate was used up to 0.05 mm to 10 mm depending on the construction thickness, and the granular type used a rough surface to maximize the adhesive area between the aggregate and the cement paste.

In the powder composition of the present invention, the content of the aggregate was used up to 35 to 60% by weight in consideration of the specific gravity of the aggregate, and since the cement hardened body itself has excellent wear resistance, there is an advantage that the selection range of the type of aggregate can be widened.

The colorants used in the powder composition of the present invention include inorganic pigments and organic pigments, but organic pigments have a large coloring power but are not durable to heat and light, and thus are easy to fade in color, whereas inorganic pigments are organic. Compared with pigments, color tone is not clear, but chemically stable against heat, light, alkali, etc., and hiding power is high.

In the present invention, the chemically stable oxide-based inorganic pigments used 1.5 to 5 parts by weight with respect to the powder composition 100, and when the content exceeds 5 parts by weight, the hiding power is good, but the excess acts as impurities and the compressive strength is significantly reduced.

The aqueous PVA-based microfibers used in the powder composition of the present invention have a very high resistance to carbon-containing solvents, oils, salts and alkalis, and have excellent resistance to direct sunlight.

Hydrophilic structure with hydroxyl on the surface of fiber, it is well dispersed in liquid composition, has high elastic modulus and high adhesion performance in mixture of powder composition and liquid composition, and has a relatively small diameter to suppress and stabilize microcracks and It is very effective in increasing the mechanical properties through the crosslinking action and is effective in suppressing cracking caused by fatigue and impact load.

In addition, the surface is not exposed, so the finish is very good.

Hydrophilic PVA-based microfibers used in the powder composition of the present invention has a specific gravity of 1.26 g / cm 3, a diameter of 11 μm, a tensile strength of 9000 kgf / cm 2, and a length of 3 to 8 mm. Use wealth Less than 0.05 parts by weight is not effective in suppressing plastic cracking, and when it exceeds 1.3 parts by weight, it is difficult to produce various patterns on the construction surface.

If the length of the fiber is less than 3mm, the matrix structure is not formed and the effect of using the fiber is not seen, and when it exceeds 8mm, dispersion is not easy and the entanglement between the fibers is entangled. .

The liquid composition of the present invention mixes 35 to 73 parts by weight of PURE acrylic emulsion and 3 to 20 parts by weight of SB LATEX with respect to 100 of the liquid composition, and the solid content of the liquid composition (dried to remove the moisture content, remaining solid Refers to the material in the form) is used to adjust in consideration of the required physical properties within the range of 10 to 45% by weight. At this time, PURE acrylic emulsion is characterized by a solid content of 50 ± 2, MFFT (Minimum Film Forming Temperature) is -3 ℃, SB LATEX is a solid content of 49 ± 1.5, it is characterized in that the MFFT is -5 ℃. .

In addition, since the water resistance tends to be somewhat reduced when PURE acrylic emulsion is used outdoors, increasing the amount of inorganic waterproofing agent used in the powder composition or blending SB LATEX with excellent waterproofing property outdoors with PURE acrylic emulsion can increase the water resistance. have.

In addition, the liquid composition in the present invention is used to mix the mineral oil-based antifoaming agent up to 0.05 ~ 0.3 parts by weight with respect to the liquid composition 100 to suppress bubbles that may occur when mixing with the powder composition.

That is, by using two mixtures of the same mineral oil-based components than using one, the amount of use can be reduced and the defoaming function can be increased.

The wetting agent used in the liquid composition of the present invention uses a low viscosity wetting agent as a surfactant for uniformly mixing a mixture of one or two of PURE acrylic emulsion and SB LATEX with aggregate, and 0.25 to 0.7 weight of the liquid composition. Use wealth

In the liquid composition of the present invention, in addition to the above components, pure water in which the impurities not necessary for the cement hydration reaction are not mixed is mixed with 23.7 to 44 parts by weight of the liquid composition. Water containing impurities adversely affects condensation, hardening, strength development, volume change, etc. Therefore, groundwater is not used and tap water is used.

Hereinafter, the coating film flooring material using the hydrophilic PVA-type microfiber of such a structure, and the construction method using slip prevention are explained in full detail.

 -Whether cracks are calculated by summing crack lengths

 -Average crack size

 -Peel rate measures the area away from the construction area

 -Abrasion rate is an average value of measured thickness of wear at construction thickness

When comparing the results of the Examples and Comparative Examples of the present invention after 16 months in units of 1 month to 5 months, the surface cracks and peeling of the bottom surface did not occur in <Example 1>, and the degree of wear of the surface Was the best. In the case of <Comparative Example 1> due to excessive primer application, cracking and peeling from the bottom surface occurred from one month after construction, and after six months, more than 50% of peeling occurred, which made it inevitable. In the case of <Comparative Example 2>, the surface protective material was not applied, and it was good until one month after construction, but after that, plastic cracking, abrasion, and whitening occurred due to rainfall.

In view of the above results, the primer does not need to be applied excessively before the composition of the present invention is applied, and in order to increase the life cycle of the construction surface, the surface protective material must be laid.

Looking at the embodiment of the blending ratio for the composition of the present invention and the physical performance of the wear resistance is shown in Table 2 and Table 3 below.

Table 2 below shows the mixing ratio, and Table 3 shows the physical properties.

From the above results, as the absorption rate increases depending on whether the inorganic waterproofing material is used, it can be seen that it has a significant influence on the wear resistance. The impact resistance is improved by using hydrophilic PVA-based microfibers, and the wear resistance and slip resistance are also improved. In particular, the construction time was found to be shortened. It should be a uniform pattern to reduce the slip resistance and traffic noise during construction, but when the fiber is not used, the work is repeated to show the pattern, which increases the construction time and the quality is not uniform.
