Description

Painting method of waterproof flooring construction for warehouse}

The present invention relates to a method of constructing a waterproof flooring material, and more specifically, to a method of constructing a waterproof flooring material in a large warehouse to obtain a radiant heating effect or to express various designs such as various information signs and safety signs.

In general, the flooring of a large warehouse must be highly durable, such as abrasion resistance and impact resistance without being damaged by vibration or load due to various types of external forces, and must have sufficient friction and resistance to prevent slipping along with sufficient waterproof performance.

In addition, it must satisfy the adhesion performance to prevent defects due to floor lifting and damage, prevent noise due to friction, elasticity for comfort when driving and walking, ease of maintenance, and secure an attractive appearance due to visual exposure. A variety of functions are required.

The waterproofing method applied to the flooring of large warehouses today is mainly the exposed waterproofing method, in which a waterproofing layer is constructed directly on the base surface of the structural concrete, and no other finishing material or protective layer is placed on top of it, so the waterproofing layer is exposed to the outside as is. As a result, it is directly subject to moving loads and impacts from vehicles, cargo, pedestrians, etc., and external environmental conditions.

Among these exposed waterproofing methods, for example, the asphalt waterproofing method has the disadvantages of a complicated construction process, severe pollution, severe shape deformation due to plastic deformation due to temperature and external forces, and poor durability.

As another example, the urethane coating waterproofing method applies polyurethane-based resin to the surface to be treated to form a seamless, integrated waterproofing layer of a certain thickness, which not only has excellent watertightness, but is also easy to construct and maintain, and is resistant to ultraviolet rays and has elasticity. It is widely used in roofs, floors, sports stadiums, etc. because it is excellent, has fewer cracks, and is comfortable when walking.

However, the urethane coating waterproofing method has the drawback of relatively low durability such as tensile strength and tear strength because polyurethane, a synthetic rubber type, is used as the main waterproofing material, resulting in damage such as scratches, dents, and tears due to external forces. In addition to defects, there are problems such as water retention, swelling, peeling, and lifting that occur frequently.

Meanwhile, in Korea, due to the nature of the climate, there is a large temperature difference between seasons, which causes significant expansion and contraction of structural concrete, so the waterproofing method using waterproofing materials with a low expansion coefficient such as cement, epoxy, and FRP (Fiber Reinforced Plastics) is used in structural concrete. It cannot follow the behavior of the device and defects due to cracks frequently occur.

Therefore, it is necessary to develop a waterproofing method that takes into account not only performance such as visual beauty considering the aesthetic aspects of the user, but also functional aspects and defects.

The background or prior art described above is information possessed by the present inventor or acquired in the process of deriving the present invention, and is only intended to help understand the technical significance of the present invention, and is information to which this invention belongs before filing the application for the present invention. It should be noted that this does not mean that it is a widely known technology in the field.

As shown in Figures 1 to 3, the method of constructing a waterproof flooring material for a large warehouse according to an embodiment of the present invention includes a scratch forming process (S101), a placement groove forming process (S103), a foreign matter removal process (S105), and undercoat film formation. It includes a process (S107), a carbon fiber yarn placement process (S109), a middle coat forming process (S111), and a top coat forming process (S113).

(a) Scratch formation (S101)

Scratches are formed on the bottom surface 10 of the structural concrete at regular intervals using a grinder or grinder.

For example, by scratching the bottom surface 10 using a ceramic grinding blade or a diamond grinding blade, the effect of preventing slipping and increasing friction can be obtained.

Here, if there is an old coating film on the floor surface 10 or if it is being repainted, it is desirable to completely remove vulnerable parts where defects and damage such as swelling, peeling, cracks, oil, rust, etc. of the base surface have occurred using a high pressure washer.

(b) Formation of arrangement groove (S103)

Arrangement grooves 11 are formed in a grid shape at regular intervals on the scratched floor surface 10.

That is, in order to bury the carbon fiber yarn 30 into the bottom surface 10, an arrangement groove 11 is dug in the bottom surface 10 at regular intervals in the horizontal and vertical directions and deeper than the thickness of the carbon fiber yarn 30. .

At this time, the arrangement grooves 11 can be arranged in a grid shape on the bottom surface 10 using a joint cutter, etc.

Here, the arrangement groove 11 can also serve as an expansion joint that absorbs expansion and contraction in order to prevent cracks from occurring due to expansion and contraction or vibration due to temperature changes of the floor surface 10.

(c) Removal of foreign substances (S105)

Remove foreign substances from the bottom surface 10 where the placement groove 11 is formed.

That is, foreign substances that interfere with the formation of the waterproof layer, such as cement powder or debris generated in the process of forming the scratches and placement grooves 11, are completely removed with a broom or vacuum cleaner to ensure the adhesive performance of the waterproof primer.

At this time, foreign substances such as dust and sand are washed with water, etc., and then cleaned with a broom or vacuum cleaner to easily and cleanly remove the foreign substances so that the intersection of the horizontal and vertical grooves 11 are not blocked. can do.

Here, if the process of forming the base film 20 is performed while the slab of the floor surface 10 is not completely dried, separation occurs between the surface of the floor surface 10 and the base film 20 after construction, so it must be completely dried. The waterproofing primer must be uniformly applied for post-base treatment and attachment of the base film (20).

(d) Undercoat film formation (S107)

The base coat (20) is evenly applied on the floor surface (10) from which foreign substances have been removed, by evenly applying a waterproof primer to form a waterproof coating layer that strengthens the constructability and adhesion of the middle coat (40) and strengthens the concrete and increases surface strength. form

That is, after removing foreign substances, one or more types of waterproof primer selected from acrylic resin or urethane resin is uniformly applied to the floor surface 10 with a thickness of less than 1 mm using a brush, roller brush, or airless spray gun to form an undercoat film ( 20) is formed.

At this time, in order to prevent the undercoat film 20 from lifting, it is desirable to apply at least one type of acrylic resin or urethane resin and then dry and cure it for at least 1 to 24 hours at room temperature (20 to 25°C). .

Here, the acrylic resin preferably contains 60 ± 10% solid content and has a viscosity of 1,600 cps or more, and the urethane resin preferably contains 90 ± 5% solid content and has a viscosity of 3,000 to 5,000 cps. .

Additionally, acrylic resin and urethane resin may be solvent-based or non-solvent-based, respectively.

(e) Carbon fiber yarn placement (S109)

The carbon fiber yarn 30 is inserted and placed into the arrangement groove 11 where the undercoat film 20 is formed.

That is, the carbon fiber yarn 30 is filled in the arrangement groove 11 in the form of a plurality of bundles, and a heating effect is obtained by warming the floor surface through heat generated by power supply.

In addition, after forming the base film 20, an electric circuit is formed in the arrangement groove 11 to arrange the light emitting elements 60 having a lighting function according to the application of power.

The carbon fiber yarn 30 is preferably arranged so that its high edge is lower than the surface of the bottom surface 10 so that it is fully filled into the arrangement groove 11.

For example, convenience of construction is achieved by flattening the bottom surface 10 and the carbon fiber yarn 30 with the load of the roller with a work tool attached to a roller so that the carbon fiber yarn 30 is embedded into the placement groove 11. can be secured and the stability of the substrate can be maintained.

In addition, it is desirable to protect the carbon fiber yarns 30 located at the longitudinal and horizontal intersections of the arrangement grooves 11 from being connected to each other by wrapping the outer portion with a crisscross-shaped insulating sheath.

Of course, in order to prevent the carbon fiber yarn 30 from moving during this process, it can be stably fixed in the placement groove 11 using an adhesive, putty, or fixing band.

Meanwhile, the carbon fiber yarn 30 may have a structure in which many carbon fiber yarns form a bundle.

In addition, the light emitting elements 60 are arranged at regular intervals along the length of the carbon fiber yarn 30 and emit light when power is applied.

At this time, the light emitting element 60 has a specific shape and pattern to express various designs such as shapes indicating dividing lines, leader lines, logos, advertisements, directions, etc., as well as various prohibition signs, warning signs, instruction signs, guide signs, and safety signs. It can be placed as .

For example, as shown in FIG. 3, the carbon fiber yarn 30 is placed in the horizontal and vertical arrangement grooves 11, and then the light emitting element 60 is placed at a specific position to form an arrow shape. When power is applied, the light emitting element emits light to form a sign that guides the direction of movement.

(f) Moderate film formation (S111)

A waterproof primer to reinforce the waterproof function is evenly applied on the base film 20 on which the carbon fiber yarn 30 is disposed to form a middle coat 40.

That is, after arranging the carbon fiber yarn 30 in a certain pattern on the bottom surface 10, one or more types of waterproofing primer selected from acrylic resin or urethane resin (polyurethane) is brushed uniformly over the entire surface with a thickness of less than 1 mm. Form the intermediate film 40 by uniformly applying it with a roller brush or airless spray gun.

At this time, in order to prevent the lifting phenomenon of the intermediate coating 40, it is preferable to apply at least one type selected from acrylic resin or urethane resin and then dry and cure for at least 1 to 24 hours at room temperature (20 to 25 ℃). do.

Here, the acrylic resin preferably contains 60 ± 10% solid content and has a viscosity of 1,600 cps or more, and the urethane resin preferably contains 90 ± 5% solid content and has a viscosity of 3,000 to 5,000 cps. .

Additionally, acrylic resin and urethane resin may be solvent-based or non-solvent-based, respectively.

(g) Top coat film formation (S113)

A coating material is applied on the middle coat 40 to form the top coat 50.

That is, the top coat film 50 is formed by uniformly applying the coating material paint to a thickness of less than 1 mm on the middle coat film 40.

For example, the top coat 50 is made of a polyurea resin such as urea acrylate, which has excellent tensile and tear strength and excellent impact resistance, abrasion resistance, durability, and corrosion resistance, and is uniformly applied using a brush, roller brush, or airless spray gun. After application, it is advisable to dry and cure for at least 7 days at room temperature (20-25℃).

Here, the coating material includes a coloring agent for realizing the color of the top coat 50, and the coloring agent includes 10-30 parts by weight of modified silicate, 5-25 parts by weight of epoxy resin, and 10-35 parts by weight of aldehyde resin. After decomposition reaction to make a polymer compound, 10-50 parts by weight of pigment and 0.5-2 parts by weight of dispersant can be added to enable nano-spraying.

Meanwhile, the coloring agent was stirred at room temperature at 100 rpm while adding distilled water and stirred evenly for 1 hour. When hydrolysis began, the stirring speed was set to 200 rpm and reacted at room temperature for 2 hours to obtain a poly-modified silicate aqueous solution. Next, epoxy resin and aldehyde resin are sequentially added and stirred to prepare a high-concentration binder, and a highly weather-resistant pigment is added thereto, and after preliminary dispersion for 30 minutes, it can be finally prepared using a nano disperser.
