The "waterproof flooring composition" of Patent No. 1012000 has high adhesion strength, high impact resistance, high abrasion resistance and hardness by chemically bonding with hydroxyl groups on the surface of concrete, and does not contain VOC, so it does not contain organic compounds or harmful gases during and after construction. It does not occur, has good water resistance, and has good fluidity before curing, so that a flat bottom surface can be obtained by the self-leveling function.

On the other hand, Patent No. 1798872 "Water-based emulsion-type heat-insulating and waterproof flooring composition for reducing urban heat island phenomenon" contains 20 to 35 parts by weight of cyclohexyl methacrylate-silicone modified acrylic copolymer resin, 15 parts by weight of rutile-based titanium oxide ~ 20 parts by weight, 4 to 8 parts by weight of spherical nanoceramic silica with a diameter of 1㎛ or less, 20 to 25 parts by weight of calcium carbonate, 2 to 3 parts by weight of propylene glycol, 0.08 to 1 part by weight of biocide, 0.08 to 1 part by weight of ammonia water , 0.5 to 0.6 parts by weight of Texanol, 0.3 to 0.4 parts by weight of an antifoaming agent, and 0.3 to 0.5 parts by weight of a dispersant, and is a water-based emulsion-type thermal insulation waterproof flooring composition diluted in water.

The above patent No. 1798872 titled "Aqueous emulsion-type thermal insulation and waterproof flooring composition for reducing urban heat island phenomenon" can improve stain resistance, wash resistance, water repellency, weather resistance, elasticity and low-temperature dependence, and has waterproof and heat insulation performance compared to the existing ones. There is an effect that can be improved without affecting the physical properties.

Comparison of physical properties between Examples and Comparative Examples 1 and 2 Properties Example Comparative Example 1 Comparative Example 2 weather resistance O O O repaintability O O O UV resistance O O X stain resistance O O O water repellency O O O water resistance O O O

From Table 2, it was confirmed that all of Examples and Comparative Examples 1 and 2 could be used for waterproofing construction flooring, except that the composition of Comparative Example 2 lacked UV resistance.

Next, the composition for waterproofing construction flooring according to the present invention, the method for waterproofing flooring using the same, and the action of the system will be described in detail.

First, in the construction flooring waterproof composition of the present invention, as shown in FIG. 3, in the construction flooring placing process (S1 step), a building flooring panel (FP) of a certain size is placed on the conveyor belt 10, and the flooring waterproof composition supply process In (S2 step), the flooring waterproofing composition is supplied to the brushes 20 and 20' installed on both sides of the conveyor belt 10, and then the construction flooring panel is moved while the conveyor belt 10 is moved in the side coating step (S3 step). The flooring waterproofing composition is applied to both sides of the (FP) with brushes 20 and 20'.

Here, the moving speed of the conveyor belt 10 is 10 to 14 m/min so that the waterproofing composition for building flooring can be applied in a uniform thickness, and it is preferable to dry the waterproofing composition for building flooring after application. When the moving speed of the conveyor belt 10 is slower than 10 m/min, the thickness of the waterproofing composition for the applied building flooring material is undesirably thick, and when the moving speed of the conveyor belt 10 is faster than 14 m/min, the applied building flooring material is undesirably thick. It is not preferable that the thickness of the waterproofing composition is thin.

Then, in the top surface application process (S4 step), the first robot applicator 30 applies the flooring waterproofing composition to the top surface of the building flooring panel (FP), and in the front surface application process (S5 step), the second robot applicator 30 '), the flooring waterproofing composition is applied to the front side of the building flooring panel (FP), and in the backside application process (step S6), the flooring waterproofing composition is applied to the backside of the building flooring panel (FP) by the third robot applicator (30"). After coating, the flooring waterproofing composition applied to the outer surface of the building flooring panel (FP) is dried in the drying process (step S7), and the flooring waterproofing composition is applied to the outer surface of one building flooring panel (FP) by repeating steps S1 to S6. The process of applying the composition is finished.

Here, the moving speed of the conveyor belt 10 is 10 to 14 m/min even in the top coating process (S4 step), the front coating process (S5 step), and the back coating process (S6 step) to make the waterproofing composition for building flooring uniform. It can be applied in thickness, and it is preferable to dry the composition for waterproofing construction flooring after application. When the moving speed of the conveyor belt 10 is slower than 10 m/min, the thickness of the waterproofing composition for the applied building flooring material is undesirably thick, and when the moving speed of the conveyor belt 10 is faster than 14 m/min, the applied building flooring material is undesirably thick. It is not preferable that the thickness of the waterproofing composition is thin.

In this way, after placing another building flooring panel (FP) again, steps S1 to S6 are repeated to build one set [15 building flooring panels (FP) having a thickness of 11 mm to 15 mm] of building flooring panels (FP) ) is prepared by applying the flooring waterproofing composition.

As described above, the construction flooring panels (FP) are removed one by one at the construction site and constructed as flooring materials, and between the construction flooring panels (FP) and the construction flooring panels (FP), the silicone finishing material is used to finish the construction of the waterproof floor. will complete

Although the present invention has been described as a preferred embodiment so far, the composition according to the embodiment of the present invention has excellent physical properties compared to Comparative Examples 1 and 2, and a robot applicator or QQMFJTNL applicator is superior to a brush. The present invention is not limited thereto, and within the scope of not departing from the gist of the present invention, substitution of equivalents among constituents including the composition according to the present invention, change of mixing ratio, and furthermore, a rotary brush applicator and a robot applicator according to the present invention Any means that can be substituted can be variously modified and implemented, and substitution of such equivalents, change of mixing ratio, and conversion of application means are naturally included in the scope of the present invention and constitute infringement of rights.
