ROOT ISOLATION SHEET AND WATER PROOFING SHEET HAVING FUNCTION FOR INDICATING ADHESIVE STRENGTH}

The present invention relates to a waterproofing and waterproofing sheet which is formed by forming a joint by overlapping one of the waterproofing and waterproofing sheet on one side and the other waterproofing and waterproofing sheet on the other side using a fusion method. By making it possible to visually identify the temperature change of the joint and the magnitude of the pressure applied to the joint, the optimal temperature and pressure can be provided to the joint of the waterproof and waterproof sheet during the fusion joint construction. The present invention relates to a waterproof and waterproof sheet having a bonding ability identifier which enables to improve.

In general, waterproof construction is essential on the roof of a building structure or an upper surface of a parking lot to prevent leakage due to rainfall. Various kinds of waterproofing methods are used for this purpose, and the waterproofing of the mortar liquid, the waterproofing of water-soluble or oil-soluble coating, the waterproofing of asphalt, the waterproofing and the waterproof sheet are used.

Among them, the waterproofing and waterproofing construction using sheets made of synthetic rubber, synthetic resin, or rubberized asphalt with excellent elasticity is made of waterproof and waterproof sheet of a certain standard, and it adheres firmly to the floor or wall surface, thereby raining from the outside. To cope with.

This waterproof and waterproof sheet is a waterproof method that forms a waterproof layer by spreading sheet-shaped waterproof material on the floor to be waterproofed, and is widely used today because of its advantages of relatively simple construction and short construction period. One of the methods.

The waterproof and waterproof sheet used for waterproofing such a sheet is roll-shaped waterproof and rootproof having a predetermined width and length (usually 1 to 2 m in width and 10 to 20 m in length) at the factory to facilitate construction and handling in the field. The sheet is manufactured and installed at predetermined intervals on the roof, wall, etc., which require waterproofing as described above.

In general, in the case of rubberized asphalt waterproofing and waterproof sheet, the overlapped portion is heated and melted by using a heat mechanism such as a torch or a hot air blower, and in the case of a synthetic resin or a synthetic rubber waterproof sheet, an adhesive or an adhesive tape is applied. It is used to bond by using (EPDM sheet, PVC sheet, TPO sheet, etc.), by using solvent, or by hot air welding using hot air welding machine (PVC sheet, TPO sheet, ECV sheet, HDPE sheet, etc.). .

As shown in Figure 1, the waterproof method is a waterproof and waterproof sheet 10, 20 for the floor is constructed on the floor, such as the roof of the building as shown in Figure 1, the waterproof and waterproof sheet manufactured to a predetermined width as described above As a splicer on the bottom surface of the waterproof and waterproof sheet and the upper surface of the bottom side waterproof and waterproof sheet overlapping the bottom as shown in FIG. Hot heat is swept together to make the waterproofing and waterproofing sheets 10 and 20 fused to each other, and at the same time, the upper portion of the overlapping waterproofing and waterproofing sheets is pressed using a roller R so as to make a stronger attachment.

Securing the watertightness of the joints is one of the most important performances in constructions that require watertightness, such as waterproofing, and the factors affecting the watertightness can be found at the joints of the sheets.

Sheet waterproofing material is a factory-produced product, which has excellent quality stability such as tensile strength and physical properties of the sheet.However, many joints must be made in order to be applied in the field, so the joint stability between sheets can be an important factor in reducing waterproof defects. have. In particular, the frequency of defects may increase when waterproofing and waterproofing sheets are installed on the complex surface.

Table 1 below shows the frequency of defects for major waterproofing materials.

As can be seen from the above table, the defect occurrence rate generated in the sheet waterproofing method capable of forming a homogeneous waterproof layer by factory production mainly depends on problems of the joint, such as poor joint construction and lack of joint strength.

That is, the sheet material is sensitive to temperature and is affected by winter or summer work, and there is a problem in that the waterproofing performance is degraded or leaks due to breakage due to partial bonding failure and insufficient stability. Even if it is in the state of being seen, it is shown to be visually bonded. Therefore, when the temperature of the waterproof layer rises and falls between -10 ℃ and 70 ℃ due to seasonal factors as in Korea, when the tensile stress occurs in the sheet joint due to thermal shrinkage of the sheet, the joint in the temporary joint state is Interfacial separation occurs, leading to water leakage.

In other words, in the sheet waterproofing method, the joints must be formed by a hot air blower when the sheets are overlapped with each other, and thus the joint properties between the sheets may vary depending on atmospheric temperature and humidity conditions, water and moisture conditions of the sheet and the base surface, and the shape of the base surface.

Eventually, the sheet surface is melt-bonded by heating the sheet surface using a hot air blower during the joining process of the sheet. At this time, when the heat is weak, the sheet is constructed without melting, and at first, the bonded interface is separated. If the heat is excessive, a sheet is melted and a hole is broken or a material is decomposed into a pyrolysis, and defects caused by this problem are shown in FIGS. 2A and 2B.

Recently, an automated hot air machine has been developed, and an automated hot air machine that controls the temperature of the hot air, the load of the pressing roller, and the moving speed of the roller is spreading in the field, so that the constant hot air condition, that is, the temperature / moving speed of the hot air fan can be constantly adjusted. Since the operator has to operate the temperature / speed of the automatic hot air heater according to the type of sheet, it may adversely affect the bonding properties.

That is, even if the hot air temperature is high, the sheet receives less heat when the moving speed is high, and the surface of the sheet may be poorly melted. When the moving speed is low, even when the hot air temperature is low, the sheet receives a moderate amount of heat, and thus a stable joint may be formed. .

Therefore, determining the hot air temperature and the moving speed of the hot air fan according to the type of sheet depends on the judgment of the operator, so waterproofing by skilled workers is very important.

In addition, if there are local irregularities, protrusions, and sand on the base surface, the pressure of the Nurum roller of the hot air fan may be locally inhomogeneous, resulting in partial fusion failure of the joint. In this situation in Esau, it is necessary to allow the roller to pressurize the sheet at a uniform pressure, and it is necessary to immediately grasp such a situation and take appropriate measures to achieve good waterproof construction.

The present invention has been made in order to solve the above problems, by allowing the naked eye to identify whether the joint portion of the waterproof and waterproof sheet attached to hot air is heated to a suitable temperature to visually identify the bonding properties, hot air temperature and The operator can easily control the movement speed of the hot air fan to achieve a good waterproof construction, and make it easy to check the local bonding defects that may be caused by the uneven press pressure of the press roller due to unevenness or sand on the waterproof surface. By making it possible for the operator to immediately apply the appropriate pressing pressure to the part identified as insufficient pressing pressure, it is possible to increase the completeness of waterproofing construction and according to the condition of the joint of waterproof and waterproof sheet even if it is unskilled Its purpose is to ensure that appropriate measures can be taken immediately. The.

The above object is, in the waterproofing and waterproofing sheet to form a joint by overlapping one of the waterproofing and waterproofing sheet one side and the other waterproofing and waterproofing sheet other side using a fusion method, the waterproofing and waterproofing corresponding to the bonding part It is formed continuously or discontinuously along the longitudinal direction on one side of the sheet, characterized in that it comprises a non-reversible temperature-sensitive color change ink (A) which is discolored as the waterproofing and waterproofing sheet is changed by the heat applied to the waterproofing and waterproofing sheet It is achieved by a waterproof and waterproof sheet having a bonding ability identification function.

Here, the irreversible pressure-sensitive discoloration ink which is formed continuously or discontinuously along the longitudinal direction on one side of the waterproofing and waterproofing sheet corresponding to the joint part and discolored according to the magnitude of the pressure applied to the bonding part of the waterproofing and waterproofing sheet ( It is preferable to further include B).

On the other hand, the above object, in the waterproofing and waterproofing sheet to form a joint portion by overlapping one of the waterproofing and waterproofing sheet one side and the other waterproofing and waterproofing sheet other side using a fusion method or an adhesive method, It is formed continuously or discontinuously along the longitudinal direction on one side upper portion of the waterproof and waterproof sheet, and includes an irreversible pressure-sensitive discoloration ink (B) that is discolored according to the magnitude of pressure applied to the junction of the waterproof and waterproof sheet. It is also achieved by a waterproof and waterproof sheet having a bonding ability identification function.

First, the present invention can be confirmed through the irreversible temperature sensing type color change ink (A) of the junction portion of the waterproof and waterproof sheet, the temperature of the junction heated by hot air at the time of fusion welding the waterproof and waterproof sheet The operator can visually identify whether a suitable temperature has been reached, thereby preventing the problem of deterioration of adhesion performance due to partial adhesion failure in an invisible portion, and thus, even after a long period of time, It has the effect of preventing breakage due to poor adhesion and peeling phenomenon of the joint.

Secondly, when fusion splicing by pressing the joint of the waterproof and waterproof sheet, the irreversible pressure-sensitive discoloration ink makes it possible to visually identify whether the joint is evenly and evenly applied to the joint according to the state of the base surface. When the pressure is not evenly transmitted because the floor is not uniform, it is possible to adjust the moving speed of the roller or to immediately take countermeasures to the worker, thereby improving the joint construction completeness of the joint.

Third, when the operator directly proceeds to join the joint of the waterproof and waterproof sheet as described above, the working state and the bonding performance or waterproof and water through the irreversible temperature-sensitive color change ink and irreversible pressure-sensitive color change ink The physical properties of the sheet can be visually identified, and accordingly, even if you are not skilled, it is possible to take countermeasures according to the change in the physical properties of the water repellent sheet and the work speed. Have

Figure 2a, Figure 2b is a photograph of the defects generated due to partial bonding failure after the conventional waterproof and waterproof sheet construction.
3 is a view showing the structure of the waterproof and waterproof sheet according to the present invention.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying FIG. 3.

The weatherproof sheet 100 according to the present invention is a conventional waterproof and waterproof sheet 100 fused with hot air such as PVC, PE, PP, EVA, TPO synthetic polymer waterproof sheet 100, improved asphalt-based waterproof sheet 100, etc. In the following description, the waterproof sheet 100 is referred to as a combination of waterproof and waterproof sheet.

And, as shown in the present invention, the bonding capability identification function, irreversible temperature-sensitive color change ink (A) and irreversible pressure-sensitive color change ink formed on the surface of the junction 200 of the waterproofing and waterproof sheet 100 as shown in FIG. By (B) it means that the operator can visually identify the physical properties of the junction portion 200 in the field.

That is, the irreversible temperature-sensitive color change ink (A) according to the present invention, when waterproofing construction of any one waterproof sheet 100 and the other waterproof sheet 100 in succession, two waterproof sheet 100 The one side of the waterproof sheet 100 and the other one of the other waterproof sheet 100 is overlapped with each other is overlapping construction is made, as described above in the overlapping construction by heating the waterproof sheet 100 with hot air When the physical properties of the both sides of the waterproof sheet 100, the junction portion 200 is changed to a temperature suitable for fusion, it is to be fused to each other by pressing while overlapping the two.

Here, as shown in FIG. 3, the irreversible temperature-sensitive color change ink (A) formed on one side of the waterproof sheet 100 is heated as the junction part 200 of the waterproof sheet 100 is heated by hot air (temperature As it rises) the color changes color.

As a result, the worker who heats the junction 200 of the waterproof sheet 100 with hot air visually identifies the state of discoloration of the irreversible temperature-sensitive color change ink A and checks whether the physical properties of the junction 200 reach a temperature suitable for fusion. Being able to grasp in real time, it is possible to perform a stable joint construction.

In addition, as described above, the physical properties of the joints 200 of the waterproof sheet 100 may be visually identified by an operator at the site, thereby achieving a high degree of perfection of construction, thereby fundamentally solving a problem of partial joint state. Even if you are not an experienced person, you can perform the work smoothly even by changing the color of the irreversible temperature-sensitive color change ink (A). It will have the effect that the problem does not occur.

In addition, among the hot air blower 300 that applies hot air to the junction portion 200 of the waterproof sheet 100, the hot air supply and hot air supply while automatically moving the junction portion 200 of the waterproof sheet 100 while automatically blowing hot air of a suitable temperature. Automated hot air is provided to provide the pressing pressure through the roller (R) at the same time so that the bonding construction can be carried out more easily and easily, as mentioned in the conventional description, the physical properties suitable for bonding the waterproof sheet 100 Due to the constant change of environmental factors, the hot air blown from the automated hot air blower and the size of the moving speed and the pressing pressure of the automated hot air blower due to the irregularity of the change of physical properties of the waterproof sheet 100 may result in partial joint failure. The problem is bound to occur.

Therefore, even when the bonding construction is performed using the automated hot air blower, the worker always grasps the physical properties of the waterproof sheet 100 as the discoloration state of the irreversible temperature-sensitive color change ink A and responds accordingly. By being able to take it quickly, it is possible to increase the degree of completeness of the work.

In the present invention, as described above, in the bonding construction using the fusion or adhesive of the waterproof sheet 100, by pressing the joints 200, which are overlapped joints, by using a roller R made of a weight body, adhesion and bonding properties can be improved. As described in the related art, when the roller R having a predetermined width provides the pressing pressure to the joint part 200 according to the condition of the base surface, if the bottom surface is not uniform, the pressing pressure by the roller R is waterproof. It may not be evenly transmitted to the bonding portion 200 of the sheet 100 may cause a problem of partial bonding failure.

Therefore, in the present invention, the irreversible pressure-sensitive discoloration ink (B) may be formed adjacent to the irreversible temperature-sensitive discoloration ink (A) according to the characteristics of the waterproof sheet 100, and may be adhesive without depending on fusion. In the case of the waterproof sheet 100 to bond the waterproof sheet 100 by using the only irreversible pressure-sensitive color change ink (B) is formed alone to enable the bonding construction.

That is, the waterproof sheet 100 adopting the fusion method induces a change in the physical properties of the bonding portion 200 through hot air supply, and after a suitable physical property change is made, the rollers are joined to the bonding portion 200 of the waterproof sheet 100 overlapping each other. Since the pressing pressure is provided by using (R), it should be possible for the operator to identify in real time whether a suitable pressing pressure is uniformly provided to the joint 200.

Here, the waterproof sheet 100 adopting the adhesive method is not necessary to change the physical properties of the bonding portion 200 by hot air supply, so that irreversible temperature-sensitive color change ink (A), and irreversible pressure-sensitive color change ink (B) Utilization becomes high.

Therefore, it is preferable to form only the irreversible pressure-sensitive color change ink (B) on the surface of the bonding portion 200 of the waterproof sheet 100 adopting the adhesive method.

On the other hand, when the irreversible pressure-sensitive color change ink (B) is formed on one surface corresponding to the joint portion 200 of the waterproof sheet 100 using the fusion method or the waterproof sheet 100 using the adhesive method, as described above When the pressing pressure is provided to the joint part 200, the bottom is not uniform, and thus the pressing pressure is not evenly transmitted.

That is, when the irreversible pressure-sensitive color change ink (B) is pressed by the roller (R), since the bottom is not uniform, the projection portion is transmitted as it is while the pressure of the roller (R), while the projection portion and the groove portion or In the protrusions and the flat portion, there is a problem that the pressure of the roller (R) cannot be transmitted because a gap occurs at the height.

In other words, when the pressing pressure is applied to the conventional waterproof sheet 100 by using the roller R, the pressing pressure is not uniformly transmitted against the nonuniformity of the bottom surface or the base surface as described above. The worker is not aware of the fact that the work is proceeded as it is, the problem of partial joint failure will inevitably occur.

However, in the present invention, since the operator can visually identify that the color of the irreversible pressure-sensitive color change ink (B) is discolored while providing the pressing pressure using the roller (R), the pressing pressure and the portion where the pressing pressure is normally provided By being able to identify the part that has not been delivered, it is possible to stop the work in progress and to compensate for the pressure where the pressure was not delivered correctly or to take appropriate action and to continue the work. Is to increase the.

As described above, in the present invention, in the case of the waterproof sheet 100 which is bonded by using the fusion method, it is possible to identify in real time whether the physical properties of the bonded part 200 are changed to a state suitable for fusion by hot air supply. Due to the excessive supply of hot air, it is possible to solve construction problems such as melting of the joint part 200 or generation of holes, and the problem of partial joint failure due to the splicing of the joint part 200 in a state suitable for fusion. It can be solved at the source.

In addition, in the case of the waterproof sheet 100 for the bonding construction using the fusion method and the waterproof sheet 100 for the bonding construction using the bonding method, both the pressing pressure by using the pressure roller (R) in both methods The joint performance should be further strengthened by providing.

However, as described above, in spite of the fact that the pressing pressure of the roller R should be provided evenly and uniformly in the joining construction, even if the floor is not uniform and the pressing pressure is not evenly transmitted, the worker visually identifies it. Since it is impossible to do so, it is inevitable to proceed with the work as it is, which causes partial bonding failure in the uneven part.

Therefore, in the present invention, when the pressing pressure is not uniformly provided as described above, the operator can directly identify the discoloration process of the irreversible pressure-sensitive color changing ink (B), so that the pressing pressure is not delivered to the part In this case, the work is stopped and the pressing pressure is reapplied to the corresponding part so that the pressing pressure can be evenly transmitted as a whole.
