Description

TECHNICAL FIELD [0001] The present invention relates to an eco-friendly urethane resin mortar lightweight flooring composition, and a method of constructing the same. BACKGROUND ART < RTI ID = 0.0 >

The present invention relates to an eco-friendly urethane resin mortar lightweight flooring composition and a method of constructing the same. More particularly, the present invention relates to an eco-friendly urethane resin mortar lightweight flooring composition and a method of constructing the same.

Conventionally, it is necessary to clean the latent or foreign matter of the concrete surface in the new and repairing flooring material of the building, clean it with a grinder and then paint it with epoxy type of oil or water paint or two-component type epoxy or urethane primer, , And then paints were applied in various ways from a thin layer of 100 microns to a thick layer of 10 mm by using general floor coating materials such as solvent-free epoxy paint and urethane paint as a top coat paint.

However, these methods cause cracks due to the hydration process, deterioration and hydrolysis of concrete, and the gas coming out of the pores, the water due to the osmotic phenomenon, and the expansion and contraction due to temperature. As a result, After 2 years, when problems occurred in the coating, cracks, peeling and lifting phenomenon of the coating were required to be repaired.

To solve these problems, various types of building flooring compositions have been developed which can be adhered well to concrete and solve the problems of hydration of concrete, deterioration and hydrolysis.

However, such conventional flooring compositions use phthalates (dioctyl phthalate, dibutyl phthalate, diisobutyl phthalate, etc.) as plasticizers.

Phthalates are chemical additives used to soften plastics, especially as a chemical ingredient used to soften polyvinyl chloride (PVC).

Diethylhexyl phthalate (DEHP) is a typical example, and it has been widely used for a variety of PVC products such as cosmetics, toys, and detergents, and for home flooring. However, it is currently prohibited to be classified as an environmental hormone.

Although the phthalate-based material is an environmental hormone-predicting material as described above, it is still used as a plasticizer of a flooring composition and thus is not environmentally friendly.

In addition, the conventional general urethane flooring and epoxy flooring are not good in heat resistance and chemical resistance, are not good in adhesiveness, and are not environmentally friendly.

In order to solve such a problem, Korean Patent No. 10-1142944 and Japanese Patent No. 10-1088748 disclose a technique of using a plasticizer which is not a phthalate-based plasticizer.

On the other hand, the conventional flooring has a disadvantage in that the specific gravity of the mortar constituting the flooring is as high as about 1.9 to 2.0, which increases the weight of the building and the usage amount of the material.

Korean Patent No. 10-1142944 Korean Patent No. 10-1088748

It is an object of the present invention to provide an eco-friendly urethane resin mortar lightweight flooring composition and a method of constructing the same, which are economical by reducing the weight and use amount of the building due to low emission of pollutants and low specific gravity.

In order to achieve the above object, an eco-friendly urethane resin mortar lightweight flooring composition of the present invention comprises 35 to 50 wt% of a natural polyol made of vegetable oil, 3 to 10 wt% of glycol, 2 to 5 wt% of defoamer and defoamer, 1 to 5 wt% 15 to 25 wt% of a plasticizer, 5 to 10 wt% of an inorganic pigment, and 15 to 25 wt% of water; A curing agent composed of diphenylmethane diisocyanate; A mortar composed of 15 to 30 wt% of portland cement, 30 to 40 wt% of silica, 25 to 45 wt% of lightweight aggregate, and 1 to 10 wt% of lime, wherein the glycol is selected from the group consisting of ethylene glycol, propylene glycol and butylene glycol Wherein the plasticizer is composed of a phthalate component, the diphenylmethane diisocyanate has an NCO content of 30 to 32 wt%, and the lightweight aggregate comprises soda lime glass.

The antifoaming agent and the defoaming agent are composed of a nonvolatile modified polysiloxane-based agent, and the emulsifying agent is made of stainless steel.

The mortar further comprises 0.1 to 1 wt% of a polycarboxylic fluidizing agent, wherein the mortar is composed of 30 to 40 wt% of the lightweight aggregate composed of soda lime glass having a diameter of 0.1 to 0.5 mm.

The resin base and the curing agent are mixed at a weight ratio of 1: 1, and the urethane resin mixed with the resin base and the curing agent and the mortar are mixed at a weight ratio of 1: 1.5 to 2, and the applied coating thickness is applied at 2 to 6 mm.

Alternatively, the lightweight aggregate may be a mixture of soda lime glass and aluminosilicate.

At this time, the mortar is composed of 15 to 30 wt% of the soda lime glass having a diameter of 0.1 to 0.5 mm and 10 to 15 wt% of the aluminosilicate having a diameter of 5 to 300 탆.

The aluminosilicate comprises SiO 2 , Al 2 O 3 , and Fe 2 O 3 .

At this time, the resin base and the curing agent are mixed at a weight ratio of 1: 1, the urethane resin mixed with the resin base and the curing agent and the mortar are mixed at a weight ratio of 1: 5 to 6, and the applied coating thickness is coated at 4 to 10 mm .

According to another aspect of the present invention, there is provided an eco-friendly urethane resin mortar lightweight flooring comprising: a foreign matter removing step of removing foreign matter from a construction site; A primer step of coating the flooring composition of claim 4 at a thickness of 0.5 to 1.0 mm on a construction site; And a first finishing step of coating the flooring composition of claim 4 at a thickness of 1.5 to 5 mm when the composition applied by the primer step is cured to make the flooring composition of claim 4 itself horizontal.

As described above, the eco-friendly urethane resin mortar lightweight flooring composition of the present invention and its application method have the following effects.

Because it uses environment-friendly materials, there is no emission of pollutants.

Since mortar uses lightweight aggregate of soda lime glass, the specific gravity of the flooring composition is low, minimizing the increase in the weight of the building even after completion of the construction of the flooring, and minimizing the safety of the building.

In addition, the use amount of the material constituting the flooring composition can be reduced, and an economical effect can be obtained.

Further, since the mortar comprises a polycarboxyl based fluidizing agent, the automatic horizontal performance of the flooring can be increased.

Further, since the mortar comprises aluminosilicate, the mortar can be easily applied to the mop or vertical portion because of the lack of sagging property.

≪ Automatic horizontal flooring composition >

FIG. 1 is a flowchart of a construction method according to an embodiment of the present invention, and FIG. 2 is a sectional view of a floor material to which an automatic horizontal construction method according to an embodiment of the present invention is applied.

The flooring composition of the present invention mainly comprises a urethane resin and a mortar.

The urethane resin is a mixture of a resin base and a curing agent.

Wherein the resin base comprises 35 to 50 wt% of natural polyol, 3 to 10 wt% of glycol, 2 to 5 wt% of defoamer and defoamer, 1 to 5 wt% of emulsifier, 15 to 25 wt% of plasticizer, 5 to 10 wt% of inorganic pigment, %.

The natural polyol is composed of vegetable oil such as pajama oil and palm oil.

The glycol is composed of at least one of ethylene glycol, propylene glycol, and butylene glycol.

The glycol affects fluidity and workability before curing, and affects physical and chemical performance after curing. Blistering and unevenness may occur on the surface during curing when the glycol is used excessively.

The propylene glycol in the glycol has a function of increasing the reaction rate.

The antifoaming agent and the defoaming agent are composed of a nonvolatile modified polysiloxane system.

The defoaming agent has the effect of removing the floating bubbles, and the defoaming agent has the effect of increasing the rate of floating of the bubbles.

By using the defoaming agent and the defoaming agent together, the effect of floating and removing the bubbles in the resin base can be further enhanced.

In addition, since the antifoaming agent and the defoaming agent are made of a nonvolatile modified polysiloxane-based agent, the generation of bubbles can be minimized by suppressing the generation of nonvolatility, that is, gas.

The emulsifier helps improve storage stability and quality uniformity.

Such an emulsifier is preferably made of stearic acid.

The plasticizer is composed of a non-phthalate component so that contaminants such as environmental hormones are not released.

Such plasticizers increase fluidity and workability before curing after mixing with the composition, and affect flexibility after curing.

The curing agent is composed of diphenylmethane diisocyanate.

At this time, the diphenylmethane diisocyanate preferably has an NCO content of 30 to 32 wt%.

The mortar is composed of 15 to 30 wt% of portland cement, 30 to 40 wt% of silica, 25 to 45 wt% of lightweight aggregate, 1 to 10 wt% of lime and 0.1 to 1 wt% of polycarboxylic fluidizing agent.

Portland cement was named after the cement in 1824, invented by J. Awashdin of the United Kingdom, whose cured body is similar to that produced in the British Isles of Portland.

The main component is limestone silica alumina iron oxide.

Generally speaking, this means cement, which accounts for most of the production.

The silica is also called silicon dioxide (SiO 2). It is resistant to high temperatures, has a very small expansion ratio, and is used as a main material for heat-resistant glass because of its rapid thermal change. In the present invention, the silica is added to utilize the heat resistance.

The lightweight aggregate is made of soda lime glass.

It is preferable that the mortar is composed of 30 to 40 wt% of the lightweight aggregate made of soda lime glass having a diameter of 0.1 to 0.5 mm.

The polycarboxylic fluidizing agent improves the flowability of the flooring composition, thereby facilitating automatic horizontal installation.

The resin base and the curing agent are mixed at a weight ratio of 1: 1.

The urethane resin mixed with the resin base and the curing agent and the mortar are mixed at a weight ratio of 1: 1.5 to 2 to constitute an automatic horizontal flooring. The automatic horizontal flooring is applied with a thickness of 2 to 6 mm.

The construction method of the automatic horizontal floors as described above includes a foreign matter removing step (S1), a primer step (S2), and a first finishing step (S3).

The foreign matter removal step (S1) is a step of completely removing the foreign substance of the concrete construction site (10) by a device such as a grinder, a planer, or a grinder.

As shown in FIG. 2, the primer step S2 is a step of applying the flooring composition in a thickness of 0.5-1.0 mm to the concrete construction site 10, ) Is coated on the upper surface of the first horizontal automatic flooring composition (11).

The first finishing step S3 is a step of applying the flooring composition to a thickness of 1.5 to 5 mm again when the composition applied by the primer step S2 is completely cured so that the flooring composition spreads horizontally by spreading itself to be.

The second automatic horizontal flooring composition (12) is applied to the upper surface of the first automatic horizontal flooring composition (11) by the first finishing step (S3).

At this time, since the mortar of the present invention is mixed with the polycarboxyl based fluidizing agent, the fluidity of the flooring composition can be improved and the automatic horizontal construction can be made easier.

The primary automatic horizontal flooring composition 11 formed in the primer step S2 is made thinner than the secondary automatic horizontal flooring composition 12 formed in the first finishing step S3 so that the thin flooring composition The pores formed in the construction site 10 of the concrete can be easily closed and closed so that the air in the pores of the concrete can be prevented from generating bubbles in the flooring.

Further, since the flooring composition of the present invention comprises mortar as a constituent element, it is possible to increase the adhesive force with concrete without a separate adhesive.

Further, since the same composition is used in the primer step S2 and the first finishing step S3, it is possible to prevent mutual peeling due to the physical and chemical properties of the different compositions.

Particularly, since the mortar is made by mixing lightweight aggregate made of soda lime glass, the increase in the weight of the building after the construction is minimized, thereby minimizing the decrease in the safety of the building, Can be obtained.

<Floor composition for vertical site construction>

3 is a cross-sectional view of a floor material to which a vertical part construction method according to an embodiment of the present invention is applied.

The vertical flooring flooring composition is different from that of the automatic horizontal flooring composition in terms of the composition of the mortar.

The urethane resin constituting the flooring composition is the same as the above-mentioned automatic horizontal flooring composition, and a detailed description thereof will be omitted.

The mortar is composed of 15 to 30 wt% of portland cement, 30 to 40 wt% of silica, 25 to 45 wt% of lightweight aggregate, and 1 to 10 wt% of lime.

The lightweight aggregate may be a mixture of soda lime glass and aluminosilicate.

At this time, the mortar is made by mixing 15 to 30 wt% of the soda lime glass having a diameter of 0.1 to 0.5 mm and 10 to 15 wt% of the aluminosilicate having a diameter of 5 to 300 mu m.

The aluminosilicate comprises SiO 2 , Al 2 O 3 , and Fe 2 O 3 .

The resin base and the curing agent are mixed at a weight ratio of 1: 1.

The urethane resin mixed with the resin base and the hardening agent and the mortar are mixed at a weight ratio of 1: 5 to 6 to constitute a floor material for vertical area construction, and the vertical part construction floor material is applied with a thickness of 4 to 10 mm.

The method of constructing the above-mentioned vertical flooring flooring material comprises the steps of removing foreign matters (S1) and a second finishing step (S4).

The foreign matter removal step (S1) is a step of completely removing the foreign substance of the concrete construction site (10) by a device such as a grinder, a planer, or a grinder.

In the second finishing step (S4), the vertical part construction flooring composition (13) is applied to the construction site (10), for example, a mop or a vertical part of a corner, to a thickness of 4 to 10 mm.

Since the vertical floor construction flooring composition 13 has a large amount of mortar with respect to the urethane resin, the thickness of the flooring composition 13 is thick, so that the air in the pores of the concrete does not rise and bubbles are not generated.

In addition, since the mortar contains aluminosilicate, it is possible to increase the viscosity while suppressing the fluidity of the composition, and even when the bottom material is applied to the vertical portion, the vertical portion can be easily applied without any deflection.

Other details are the same as those of the above-described automatic horizontal flooring composition, and a detailed description thereof will be omitted.
