DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

First, the bottom surface waterproofing method using the glass fiber mesh net according to the present invention can be carried out macroscopically by performing a background adjustment step (S100), a submerging step (S200), a first intermediate step (S300), a mesh net installation step (S400) (S500) and a top-up process (S600).

Specifically, the background adjusting step (S100) is a step of preparing a work by cleaning the bottom surface and repairing cracks, and a process for making the primer applied in the lower step (S200) . That is, the background adjusting step (S100) physically removes the foreign matter or the waterproofing material adhering to the wall surface to clean the floor, adjusts the floor surface smoothly and adjusts the floor, The V-cut or abraded and then filled with a sealant to clean up the bottom surface of the concrete structure 10.

In addition, all of the sealing agents may be used in general, and it is more preferable to use a resin containing a polyurethane resin, a water-soluble epoxy resin, or an acrylic copolymer resin in order to ensure adhesion with the primer shown in the sublimation process (S200) .

In addition, the priming process (S200) is a process of forming a primer layer (20) by applying a primer to the floor surface treated in the background adjusting process (S100), wherein a main waterproofing function In order to firmly adhere the first intermediate agent for applying the primer.

 In addition, the primer may be applied to a base surface of a general primer, such as a polyurethane resin, a water-soluble epoxy resin, or an acrylic copolymer resin, to a predetermined thickness. Preferably, The primer layer 20 may be formed to have a thickness of 20 to 100 탆 so as to be uniformly introduced into the primer layer 20.

At this time, the priming process (S200) may be performed by coating the primer on the bottom surface by a spraying method or a roller method according to the judgment of a person skilled in the art.

In addition, in the primary intermediate step (S300), a step of forming a first intermediate layer (30) by applying an intermediate agent of a polyurethane resin material to the upper part of the primer layer (20) And a primary layer 30 is first formed on the primer layer 20.

At this time, the intermediate agent used in the primary intermediate step (S300) may be a neutralizer generally used in a waterproofing method, and preferably a polyurethane resin material may be used.

In addition, the first intermediate layer 30 formed on the primer layer 20 in the first intermediate step S300 is configured to have a thickness of 0.3 to 5 mm when the intermediate layer is made of a polyurethane resin material desirable. That is, if the first intermediate layer 30 is formed to have a thickness of less than 0.3 mm, the thickness of the first intermediate layer 30 becomes too thin, and the water resistance of the first intermediate layer 30 becomes insufficient. The thickness of the first intermediate layer 30 is excessively thick so that the primer layer 20 and the first intermediate layer 30 or the first intermediate layer 30 and the glass fiber mesh net 40 are formed in the upper layer The first intermediate layer 30 may be easily peeled off due to an external force applied from the outside of the first intermediate layer 30. Therefore, it is preferable that the first intermediate layer 30 maintains the thickness within the above range.

In addition, the mesh netting step (S400) is a step of laying a glass fiber mesh net (40) made of a glass fiber material on the first intermediate layer (30), and the physicochemical properties To the waterproof layer.

That is, in the step S400 of installing the mesh net, the first intermediate layer 30 formed by the first intermediate step S300 is dried, and then the upper part of the first intermediate layer 30 is coated with a glass fiber mesh As a process for laying the net 40, the glass fiber mesh net 40 may be made of glass fiber in the form of a thread, and a glass fiber mesh net made by weaving the yarn- (Void space) having various sizes and shapes can be used.

In addition, the glass mesh net 40 having a predetermined width and length may be installed on the first intermediate layer 30 while unwinding the web. In order to prevent the glass fiber mesh net 40 installed on the upper portion of the first intermediate layer 30 from floating on the upper portion of the first intermediate layer 30, Or may be attached to a plurality of portions of the glass fiber mesh net 40 installed on the upper portion of the glass fiber net 30.

That is, the glass fiber tape is configured to temporarily bind the glass fiber mesh net 40 to the upper surface of the first intermediate layer 30, and during the following secondary intermediate step (S500), the glass fiber tape Removed or uninstalled.

The glass fiber mesh net 40 according to the present invention may have the same or similar material and woven form as the glass fiber mesh net 40 used in the general waterproofing method, The first coating layer 41 is formed by coating a mixture of a natural component adhesive and a diaphragm powder.

That is, it is preferable that the first coating layer 41 formed on the outside of the glass fiber mesh net 40 is formed by a coating material in which a diaphragm powder is mixed with an adhesive containing rosin and glue as a main component.

At this time, the adhesive may be an adhesive containing rosin and glue as a main component, preferably 5 to 10 parts by weight of a liquid phase of rosin and 3 to 7 parts by weight of a glue with respect to 100 parts by weight of distilled water desirable.

Specifically, the rosin is a sticky brownish sticky liquid coming from the stem of a tree attached to a pine tree. When it comes out from the damaged part of the tree, it is a colorless transparent liquid, a volatile substance evaporates over time and is sparse and sticky There is a property. In addition, rosin is soluble in ethyl alcohol, acetic acid or chloroform, but does not dissolve in water.

In addition, since the rosin is made of natural materials, the physical strength of the first coating layer 41 is improved without releasing the volatile organic substances, and when heat is applied to the waterproof layer by sunlight, the first coating layer 41 to form a first intermediate layer 30 and a second intermediate layer 50 corresponding to the outside of the first coating layer 41. The first intermediate layer 30 and the second intermediate layer 50, So that it can be positioned outside the glass fiber mesh net 40. FIG.

It is preferable that the resin having the above-mentioned composition is contained in the adhesive in a mixing ratio of 5 to 10 parts by weight with respect to 100 parts by weight of the distilled water. If the resin is contained in the adhesive in an amount less than 5 parts by weight, The effect of preventing the particles from coming off is somewhat insufficient. When the amount exceeds 10 parts by weight, the flame retardancy of the waterproof layer is somewhat lowered. Therefore, it is preferable that the resin is contained in the adhesive in the mixing ratio within the above-mentioned range.

In addition, the glue forms a bonding strength of the first coating layer 41 together with the liquefaction of the liquid phase, and improves physical strength such as tensile strength and compressive strength of the first coating layer 41.

That is, the glue is an extract obtained from animal skin or bone as a raw material. When extracting glue using leather, generally, the leather is immersed in a lime water solution, followed by hot water extraction, and the extracted solution is concentrated and cooled Solidified glue is made. When bone is used to extract glue, the bone is pre-degreased with an organic solvent, hot-extracted, and the extracted solution is concentrated and cooled to form a solidified glue.

The glue is preferably contained in the adhesive in a mixing ratio of 3 to 7 parts by weight with respect to 100 parts by weight of distilled water. When the glue is contained in an amount of less than 3 parts by weight, the tensile strength and compression The first coating layer 41 formed on the outer side of the glass fiber mesh net 40 may be excessively hardened and may be cracked if it is contained in an amount exceeding 7 parts by weight , Glue is preferably included in the adhesive at a mixing ratio within the above range.

In addition, as described above, the adhesive composed mainly of resin and glue may further include a pH adjusting agent, a neutralizing agent, and an emulsifying agent to smoothly mix the resin and the glue with distilled water.

That is, sodium hydroxide and sodium phosphate may be used as the pH adjusting agent, and ammonia may be used as the neutralizing agent.

Specifically, the sodium hydroxide is preferably contained in a mixing ratio of 10 to 15 parts by weight with respect to 100 parts by weight of distilled water by adjusting the pH of the adhesive to stabilize the liquid phase in the distilled water.

If sodium hydroxide is contained in an amount of less than 10 parts by weight based on 100 parts by weight of distilled water, there is a problem that the basicity of the adhesive is somewhat weak, so that the lyophilization of the liquid phase and the glue are less dissolved and poorly limited in the distilled water contained in the adhesive. The degree of basicity of the produced adhesive is too high and the durability of the first coating layer 41 is easily deteriorated. Therefore, sodium hydroxide is preferably included in the adhesive in the mixing ratio within the range described above.

In addition, sodium tertiary phosphate is used in combination with sodium hydroxide to adjust the pH of the adhesive to stabilize the liquid phase in the distilled water, and it is preferably contained in a mixing ratio of 3 to 5 parts by weight with respect to 100 parts by weight of distilled water Do.

If sodium tertiary phosphate is contained in an amount of less than 3 parts by weight based on 100 parts by weight of distilled water, the basicity of the adhesive is somewhat weak, so that the liquid phase of the resin is less dissolved and poorly limited in the distilled water contained in the adhesive, If the amount is more than 5 parts by weight, the degree of basicity of the produced adhesive is excessively high, and the durability of the first coating layer 41 is easily deteriorated. Therefore, sodium tertiary phosphate is preferably included in the adhesive in the mixing ratio within the above range Do.

That is, the sodium hydroxide and the sodium phosphate are constituted to adjust the pH of the adhesive, and the strong bases of different kinds are included in the adhesive in order to appropriately secure the liquid phase of the distilled water and the solubility of the glue respectively .

In addition, the ammonia is suitable for neutralizing an adhesive having a basicity by sodium hydroxide and sodium phosphate. The ammonia may be used in an amount of 0.1 to 100 parts by weight based on 100 parts by weight of distilled water depending on the composition of sodium hydroxide and sodium tertiary phosphate contained in the adhesive. And 1.0 part by weight of the adhesive.

At this time, it is preferable that the ammonia is constituted so that the final pH of the adhesive can be adjusted as ammonia by mixing the adhesive in the liquid phase after the lyophilization and the glue are appropriately dissolved in the distilled water containing sodium hydroxide and sodium tertiary phosphate.

Also, the mixing ratio of ammonia to the adhesive may be varied depending on the composition ratio of sodium hydroxide and sodium phosphate contained in the adhesive, but may be mixed at a mixing ratio of 0.1 to 1.0 part by weight with respect to the adhesive so that the adhesive may have a pH of 6 to 8 .

In addition, the emulsifier has a constitution for dissolving an oil component which may be contained in the liquid phase of the rosin or glue in the distilled water, and since the rosin or glue is a natural component, a slight oil component may be contained even if purified ones are used.

On the other hand, the emulsifier realizes the effect of emulsifying the distilled water and the oil component to prevent the oil component from floating in the adhesive. At this time, the emulsifier is preferably mixed at a mixing ratio of 7 to 10 parts by weight with respect to 100 parts by weight of distilled water, and the emulsifier can be freely adjusted within the range of the composition ratio according to the purity of the rosin contained in the liquid rosin and the purity of the glue.

In addition, any one or more of commonly known emulsifiers may be used as the emulsifier. In the present invention, any one or more of acetone, hexan-3-one or 3-bromo-cyclohexanone may be used. The above-mentioned ketone-based emulsifier does not impair the inherent properties of rosin and glue, and exerts the effect of stably emulsifying oil components contained in rosin and glue in distilled water.

The diaspore powder is obtained by pulverizing a diaspore so as to have a particulate phase. The diaspore is an aluminum oxide mixture as a hydroxide mineral containing a large amount of aluminum (Al). That is, the diaphragm contained in the coating material contains a large amount of aluminum, thereby realizing the heat shielding property that the aluminum component blocks heat transmitted to the first intermediate layer through the upper and lower intermediate layers, Thereby improving the heat resistance of the waterproof layer.

That is, due to the characteristics of the inorganic mineral, the diaphragm is contained in the first coating layer 41 on which the glass fiber mesh net 40 is coated on the outside, and the heat transferred from the sunlight is transferred to the waterproof layer (specifically, (40), and the waterproof layer can withstand high heat at the time of fire.

More specifically, the diaphragm has the effect of making the waterproof layer formed by the bottom surface waterproofing method according to the present invention have heat insulating property and heat resistance, thereby preventing the bottom surface from being heated by sunlight in summer.

At this time, it is preferable to use the powdered powder of the appropriate size in accordance with the judgment of a person skilled in the art, more preferably 200 to 500 mu m.

That is, when the average particle size of the diaphragm powder is less than 200 m, it is difficult to disperse the diaspore powder in the adhesive. When the average particle size of the diaphragm powder exceeds 500 m, the size of the particles is excessively large, ) May become uneven due to the diaphragm particles, it is preferable that the diaphragm powder has an average particle size within the above range.

The diaphragm powder may be mixed with the adhesive at an appropriate mixing ratio, and preferably, the mixing ratio of the diaphragm powder is 0.5 to 5 parts by weight based on 100 parts by weight of the adhesive.

That is, when the diaphragm powder is mixed with less than 0.5 part by weight with respect to 100 parts by weight of the adhesive, the effect of improving the heat resistance and heat resistance of the waterproof layer due to the diaphragm is somewhat insufficient. When the amount of the diaphragm powder is more than 5 parts by weight, The first coating layer 41 may be easily peeled off from the glass fiber mesh net 40 because of the adhesive force of the first coating layer 41. As a result, desirable.

In addition, the coating material may further include a puddle powder in addition to the diaphragm powder.

That is, the chalcocite is an orthorhombic sulphide mineral containing a large amount of copper (Cu), which improves the heat resistance and heat resistance of the waterproof layer due to the copper component in addition to the diaphragm.

That is, the pig iron is included in the first coating layer 41 on which the glass fiber mesh net 40 is coated, and the heat transferred from the sunlight is transmitted to the lower portion of the waterproof layer (specifically, the glass fiber mesh net 40) And the waterproof layer can withstand high heat at the time of a fire.

More specifically, the above-mentioned rhyolite has the effect of making the waterproof layer formed by the bottom surface waterproofing method according to the present invention have heat-insulating property and heat resistance, thereby preventing the bottom surface from being heated by the sunlight in summer.

At this time, it is preferable that the rhyolite is pulverized into a powder form so as to have an average particle size of 200 to 500 탆 for the same reason as the above-mentioned diaphragm, and a detailed description thereof will be replaced with a description of the diaphragm powder .

In addition, the pseudophosphite powder may be mixed with the adhesive at a proper mixing ratio, and may be mixed at a mixing ratio of 5 to 15 parts by weight, based on 100 parts by weight of the diaphragm powder.

That is, when the puddstone powder is mixed with less than 5 parts by weight based on 100 parts by weight of the diaphragm powder, the effect of improving the heat resistance and heat resistance of the waterproof layer by the puddle is somewhat insufficient, and if it exceeds 15 parts by weight, The adhesive strength of the first coating layer 41 may be lowered so that the first coating layer 41 may easily peel off from the glass fiber mesh net 40. It is therefore preferable that the pseudolite powder is contained in the coating composition within the range .

In addition, the coating material may further include tantalite powder in addition to the diaphragm powder.

That is, the tantalite powder is obtained by pulverizing tantalite so as to have a granular shape. The tantalite contains a large amount of niobium and tantalum, which are elements mainly used as a component of the corrosion-resistant metal alloy, And the glass mesh network is brought into close contact with the upper portion of the first intermediate layer 30 due to a large specific gravity (5.5 to 7.3).

More specifically, the tantalite is contained in the coating to improve the heat resistance and heat resistance of the waterproof layer, as well as to increase the weight of the first coating layer 41. As a result, the first coating layer 41 is formed on the outside The weight of the glass fiber mesh net 40 is increased so that the glass fiber mesh net 40 can be closely attached to the upper portion of the first intermediate layer 30 and can be installed.

At this time, it is preferable that the tantalite powder is pulverized into a powder form so as to have an average particle size of 200 to 500 탆 for the same reason as the above-mentioned diaphragm. would.

The tantalite powder may be mixed with the adhesive at an appropriate mixing ratio, and preferably 10 to 20 parts by weight of tantalite powder per 100 parts by weight of the diaphragm powder.

That is, when the tantalite powder is mixed in an amount of less than 10 parts by weight based on 100 parts by weight of the diaphragm powder, the weight increase effect of the glass fiber mesh net 40 by tantalite is somewhat insufficient. When the tantalite powder is more than 20 parts by weight, The first coating layer 41 may be easily peeled off from the glass fiber mesh net 40 because the mixing ratio of the first coating layer 41 and the second coating layer 41 is excessively high, It is preferable to be included in water.

The thickness of the first coating layer 41 formed outside the glass fiber mesh net 40 can be appropriately adjusted according to the type of the bottom surface of the bottom surface waterproofing method of the present invention, To 700 mu m as an average thickness.

That is, if the thickness of the first coating layer 41 is less than 300 μm, the first coating layer 41 is too thin to easily peel off the first coating layer 41 from the outside of the glass fiber mesh net 40, There arises a problem that the effect of improving the functionality by the coating layer 41 is somewhat insufficient and when the thickness exceeds 700 μm, the glass fiber mesh net 40 is not easily bent due to the excessive thickness of the first coating layer 41 It is preferable that the thickness of the first coating layer 41 is maintained within the above range.

In addition, the first coating layer 41 may be formed on the entire outer surface of the glass fiber mesh net 40, or may be formed only on the upper surface of the glass fiber mesh net 40, can do.

That is, the main purpose of the first coating layer 41 is to make the heat-shielding and waterproof layer, which blocks the heat of the waterproof layer by sunlight, have heat resistance. The main purpose of the first coating layer 41 is a glass fiber mesh net 40 on the upper surface side.

More specifically, solar heat is transmitted from the upper portion of the waterproof layer to the bottom surface in the downward direction, that is, after passing through the upper layer 60 and the second intermediate layer 50 to the first intermediate layer 30, When the first coating layer 41 is formed on the upper surface of the glass fiber mesh net 40 installed at the lower portion of the second intermediate layer 50, It is possible to realize an effect that the heat transferred to the upper portion of the heat exchanger 30 can be blocked before it is discharged into the atmosphere.

That is, since the heat received from the upper part of the waterproof layer is larger on the upper side than the lower side of the glass fiber mesh net 40 in the process of being transferred to the bottom surface, the first coating layer 41 is formed on the glass fiber mesh net 40, As shown in FIG.

At this time, the first coating layer 41 formed on the upper surface of the glass fiber mesh net 40 may be sprayed by spraying the coating material onto the upper surface of the glass fiber mesh net 40, And a roller type method of rolling the glass fiber mesh net 40 on the upper surface of the glass fiber mesh net 40. Preferably, the coating material is pre-processed in the form of a film, A thermocompression bonding method in which the thermocompression bonding is performed on the upper surface of the semiconductor chip 100.

More specifically, the first coating layer 41 is formed of a coating film in the form of a film in which a mixture of an adhesive containing rosin and glue as a main component and a diaphragm powder is formed as a film, ) Of the first and second substrates.

That is, the coating film having the above-described structure has a predetermined area formed by forming the coating to have the thickness of the first coating layer 41, and has a width corresponding to the width and the length of the glass fiber mesh net 40 And the coating is shaped so as to have a length.

At this time, the coating film is seated on the upper part of the glass fiber mesh net 40, and a thermal compression force is applied to the upper part of the coating film so that the coating film is fused to the upper surface of the glass fiber mesh net 40 .

The thermocompression process of the coating film may be performed by continuously drawing a glass fiber mesh net 40 wound in a roll form and a coating film wound in a roll into a thermocompression roller, The perforation roller further disposed on the rear portion of the pressing roller is formed with a plurality of projections on the outside so as to correspond to the empty space of the glass fiber mesh net 40, A through hole corresponding to the empty space of the glass fiber mesh net 40 may be formed on the film.

That is, when a large number of through holes are formed in the coated film thermally pressed on the upper surface of the glass fiber mesh net 40 as described above, a plurality of through holes are formed on the upper surface of the glass fiber mesh net 40, 50) flows down to the first intermediate layer 30 located below the fiberglass mesh net 40 so that the second intermediate layer 50 and the first intermediate layer 30 are separated from each other It is possible to obtain an effect of being firmly adhered.

When the first coating layer 41 is formed only on the upper surface of the glass fiber mesh net 40, a second coating layer 42 made of polyurethane resin is formed on the lower surface of the glass fiber mesh net 40, Can be formed.

That is, the second coating layer 42 has the same material as that of the first intermediate layer 30 to reduce the physical properties between the glass fiber mesh net 40 and the first intermediate layer 30, The adhesive strength between the intermediate layer 30 and the glass fiber mesh net 40 can be increased.

More specifically, the intermediate agent for forming the second intermediate layer 50 applied on the upper portion of the glass fiber mesh net 40, which is seated on the upper surface of the first intermediate layer 30 in a cured state, Formed on the upper surface of the first intermediate layer 30 and the lower surface of the first intermediate layer 30 and the lower portion of the glass fiber mesh net 40 after passing through the void space (or the through hole of the coating film) The effect of allowing the first intermediate layer 30, the glass fiber mesh net 40 and the second intermediate layer 50 to be more firmly adhered can be realized by flowing into the lower portion of the coating layer 42. [

As shown in FIG. 6, the second coating layer 42 may be formed on the lower surface of the glass fiber mesh net 40 by any one of a spraying method, a roller method, and a thermal pressing method. The glass fiber mesh 40 may be formed on the entire surface of the glass fiber mesh 40 before the first coating layer 41 is formed on the glass fiber mesh 40. In this case, 2 coating layer 42 is formed on the first coating layer 41).

In the second intermediate step S500, a second intermediate layer 50 is formed by applying an intermediate agent of a polyurethane resin material to the upper part of the first intermediate layer 30 processed in the mesh netting step S400 A second intermediate layer 50 for realizing the main waterproofing property of the waterproof layer is secondarily formed on the glass fiber mesh net 40.

At this time, it is preferable that the intermediate agent used in the secondary intermediate step (S500) is the same as the intermediate agent used for the polyurethane resin used in the primary intermediate step (S300).

The second intermediate layer 50 formed on the upper part of the glass fiber mesh net 40 in the second intermediate step S500 is configured to have a thickness of 0.3 to 5 mm when the intermediate layer is made of a polyurethane resin material . That is, if the second intermediate layer 50 is formed to have a thickness of less than 0.3 mm, the thickness of the second intermediate layer 50 is too thin, and the water resistance of the second intermediate layer 50 becomes insufficient. The thickness of the second intermediate layer 50 is excessively thick so that the second intermediate layer 50 may easily peel off from the upper portion of the glass fiber mesh net 40, It is preferable to maintain the thickness within the above range.

In addition, the upper phase step (S600) is a step of forming an upper layer (60) by applying an upper agent to the upper part of the second intermediate layer (50), wherein the second intermediate layer (50) The upper layer 50 is coated with a top coat agent and can be processed using a general top coat agent having waterproof property in the same manner as the top coat step S600 of the general waterproofing method.
