Description

[0001] METHOD FOR CONSTRUCTING FLOOR USING NONSLIP FLOORING MATERIAL [0002]

The present invention relates to a floor construction method using a non-slip flooring.

With the development of the industry, the use of floor coatings for cleanliness and finishing in various living and working environments is rapidly increasing, and after the concrete buildings such as parking lots, hospitals, schools, department stores are completed, The floor is protected and painted with epoxy or urethane floor coatings for exterior finish. The above-mentioned floor paint makes it possible for a vehicle or a pedestrian who goes in and out to freely walk and walk comfortably and to prevent leaking of concrete from the rainwater or the like.

The floor coated with the epoxy or urethane floor coating may cause sliding due to the water film phenomenon caused by moisture and oil, which may cause an accident that threatens the safety of the pedestrian and the driver. Particularly, in a parking lot, a factory, a food factory, a kitchen, a gas station, a swimming pool, a ship, a bathroom, etc., water and oil are continuously generated on the floor. Further, the coating film surface formed by the epoxy or urethane floor coating has a problem that an unpleasant friction noise is generated when the vehicle is operated on foot.

In order to solve the above-mentioned problems, the ground is mixed with the high-hardness silica powder, but the high-hardness silica powder has a high specific gravity, which complicates the construction method and the durability is poor.

In order to solve the above problems, the present invention provides a floor construction method using a non-slip flooring including a silane-coated polyolefin powder.

In addition, the phenomenon of aggregation of the polyolefin powder in the coating can be prevented, and the unevenness can be uniformly formed on the surface of the coating film. In addition, the polyolefin powder coated with the silane has an improved durability and can prevent the particles from falling out after the formation of the coating film. The coefficient of friction of the coating film surface can be increased to prevent slippage, and the contact area with the bottom surface is small Fricatives may be reduced when the vehicle is operated.

The polyolefin powder may be contained in an amount of 3 to 30% by weight based on the total weight of the base material for flooring. If the content of the polyolefin powder is less than 3% by weight, irregularities may not be properly formed on the surface of the coating film and the slip-preventing effect may be deteriorated.

The polyolefin pellets are pulverized to form a polyolefin powder (S10).

The polyolefin pellets may include one or more selected from polyethylene pellets, ultra high molecular weight polyethylene pellets, low density polyethylene pellets, linear low density polyethylene pellets, high density polyethylene pellets, and polypropylene pellets.

The polyolefin pellets can be freeze-pulverized in a low-temperature atmosphere of -100 ° C or lower using a liquefied nitrogen gas. The polyolefin pellets having a size of 3 to 5 mm may be pulverized into spherical or polygonal powder to form a polyolefin powder having a particle size of 1 to 1,500 μm. Since the freezing milling is not a chemical milling using an organic solvent, the milling process is simple, there is no concern about residual organic solvents, and the process cost is low.

The pulverized polyolefin powder is classified and classified into polyolefin powder having a particle size of 30 to 1,000 mu m. If the particle size of the polyolefin powder is less than 30 mu m, the particle size may be small to reduce the slip effect. If the particle size is more than 1,000 mu m, the polyolefin particles may escape from the coating film due to friction or the like.

The coating may be carried out by mixing 100 parts by weight of the polyolefin powder and 0.1-20 parts by weight of the silane, followed by rapid dispersion. If the content of the silane is less than 0.1 parts by weight, the coating effect may be insufficient because the silane content is low. If the content is more than 20 parts by weight, the content of the silane is excessively high.

The polyolefin powder coated with the silane is mixed with the polymer for flooring and the polymer curing agent (S30).

The above-mentioned polymer for flooring is not limited, but it preferably contains one or more selected from among epoxy resin, urethane resin, acrylic resin and MMA resin in consideration of compatibility with silane, and the polymer curing agent is preferably an epoxy curing agent, , An acrylic hardener, and an MMA hardener.

The pigment component may be further mixed with the base material for flooring. The pigment component may be a lead chromate salt, an iron oxide, or the like as a component that gives a coloring effect.

The mixing can be carried out using a stirrer or a dissolver. The mixing method is not limited.

2A and 2B are views for explaining a floor construction method according to embodiments of the present invention. FIG. 2A shows the overall structure of the coating film formed by the bottom construction method, and FIG. 2B shows an actual photograph of the formed coating film.

2A and 2B, a coating 100 applied on a floor F may be formed in a multi-layered structure including a lower coating 110, a middle coating 120, and an upper coating 130.

The intermediate coating 120 is a non-slip layer formed by applying anti-slip flooring comprising a polyolefin powder coated with silane. The anti-slip layer may be formed of a coating layer having a thickness of 50 to 80 mu m by a single coating or a coating layer having a thickness of 100 to 160 mu m by a double coating. The anti-slip layer may be formed by lining with a thickness of 1 to 3 mm by a single coating. When the anti-slip layer is formed of the lining, the top coat 130 may not be formed.

The anti-slip flooring may be applied over the undercoat 110 using a method selected from roller application, air spray application, and airless spray application.

The nozzle of the airless spray may have a tip diameter that is larger than the tip diameter (0.3 to 1.0 mm) of the nozzle used when applying the conventional bottom material not containing polyolefin powder, preferably 1.0 to 3.0 mm. The motor power of the airless spray may be greater than the motor power (0.6 to 2) used when applying the conventional floor material not containing the polyolefin powder, and may preferably be 4 to 10 HP.

Since the silane-coated polyolefin powder 125 has a low specific gravity and is excellent in compatibility with the epoxy resin and has good dispersibility, the polyolefin powder 125 can be uniformly distributed in the anti-slip flooring, Thereby giving an effect of giving irregularities to the surface of the coating film 100. That is, the friction coefficient of the surface of the coating film 100 is increased by the polyolefin powder 125 coated with the silane, so that sliding can be prevented. In addition, the polyolefin powder 125 coated with silane is excellent in durability and can maintain a slip prevention effect for a long period of time.
