Description

Method of joining a joint with an unsaturated polyester resin by joining the joints of a waterproof sheet having an asphalt-based waterproof coating on a PE long-fiber nonwoven fabric {Method joining a joint with unsaturated polyester resin between the complex waterproof sheets}

The present invention relates to a method of joining the joints of a waterproof sheet formed with an asphalt waterproof coating film to a PE long fiber nonwoven fabric by using an unsaturated polyester resin. After applying the primary unsaturated polyester resin at, the joint is reinforced with a fiberglass mesh having a width of about 6 ~ 10cm and the tensile strength is strengthened. Not only is the adhesion more robust, but the curing time of unsaturated polyester resin is extremely short (20-30 minutes), so that the subsequent construction process is fast and the entire construction period is efficient.

In general, the sheet waterproof is a term used for waterproofing the bottom surface of the structure, the vertical wall of the structure, the tunnel arch surface.

Since the waterproofing of the bottom surface of the structure or the vertical wall of the structure is the most basic waterproofing, it will be described based on this for convenience of description.

As a waterproof material, asphalt-based and polyurethane-based are mainly used.

Waterproofing of structures takes place in several processes. In particular, these days, it consists of a series of work processes that consist of waterproofing the film, which must be done in the field, and field work using the products produced in the factory.

The production of some products in the factory is more efficient than working in the field, and the quality of the product is superior, so the field work and dividing the factory product is a trend of development these days.

If all of the waterproofing work is done on site, not only is it significantly lower than the quality of water produced as a standard product at the factory, but it is only required to be attached to the site immediately after being produced as a factory product. Compared to this, it is less affected by the climate and the construction period is saved as much, so the construction period is faster.

If the whole process is done in the field, it is necessary to have time for curing and curing of the waterproofing material after the waterproofing material is applied. The thicker the thickness of the waterproofing material, the more it is applied repeatedly, curing time usually takes 2-3 days.

If the curing period is prolonged, it may be necessary to rebuild due to fatal damage during rainfall, so not only do you have to pay much attention to the start of construction, and there is a problem that the construction period is long because it is not possible to carry out the subsequent process.

On the other hand, if the curing period of the waterproofing material is partially replaced by the factory production from the field work, and then produced as a factory product, the curing period of the waterproofing material can be omitted, so that the subsequent process in the field can be performed faster.

Referring to the conventional waterproofing process that the whole process is performed only in the field work as follows.

The primer is first applied on the concrete base surface of the structure, and then a water-soluble rubberized asphalt is applied to form a waterproof layer thereon.

The coating thickness of the primer is about 0.3 mm. The coating thickness of the water-soluble rubberized asphalt applied thereon is usually 3 mm. Water-soluble rubberized asphalt is water-soluble, so the pinhole microcrack of the structure is infiltrated by capillary phenomenon, but it is a waterproof material with excellent waterproofing performance, but it takes a long time for curing and curing. That is, when the water-soluble rubberized asphalt is applied to a thickness of 3mm, it needs to be repeatedly applied several times. Therefore, since the first and second applied water-soluble rubberized asphalt is cured and cured, the second and third coatings are made. The curing time will be so much. In addition, there is a problem that is affected by the climate (especially rain) because it is a field work.

In this case, when the waterproofing work is performed by water-soluble rubberized asphalt, the coating thickness is thick, which requires a lot of curing and curing time, and the waterproofing work is not performed smoothly due to rainfall. The delay or interruption of the process is the biggest problem of the field work in the whole process.

Next, there is a divided method divided into field work and factory work as an improvement method for reducing curing and curing time due to the thickness of the water-soluble rubberized asphalt, which is a problem of the field work.

That is, a coating thickness of 3 mm of water-soluble rubberized asphalt is applied in a field of about 1.0-1.5 mm, and the remaining 1.5-2 mm is a method of adhering a manufactured product that has been manufactured and cured in a factory in advance.

An example is shown in FIG. 1, which will be described below.

Applying the water-soluble rubberized asphalt 20 to the concrete base surface in the field to about 1.0-1.5mm to cure, and then by applying a primer 30 on the field work is completed.

In the factory to produce a protective sheet integral waterproof sheet (S). Protective material integrated waterproof sheet (S) is a uniform thickness while allowing the anchoring and binding of the water-soluble rubberized asphalt (20) and PE long-fiber nonwoven fabric (10) formed of polyester (PE) long fibers as a waterproof film protective material integrally with each other. The factory was manufactured.

When the water-soluble rubberized asphalt 20 of the factory-fabricated protective material integrated waterproof sheet S is bonded to the primer 30 of the field work, the waterproofing is completed.

The coating thickness of the water-soluble rubberized asphalt 20 in the field is divided into half, and the remaining half of the coating thickness is manufactured in the factory, so that curing and curing time at the site is reduced, and there is room for curing and curing time at the plant. As a result, the curing and curing time of the water-soluble rubberized asphalt is greatly reduced. As it is a factory product, not only is it less affected by the climate, but the subsequent process is performed quickly, and even if the flatness of the bottom surface to which the waterproofing material is applied is uniform, the thickness of the waterproofing layer is constant by the protective material-integrated waterproof sheet (S) made of uniform thickness. There is an advantage.

The protective material-integrated waterproof sheet (S) manufactured by the factory will be described even if the rubberized asphalt is integrally attached and adhered to the PE long-fiber nonwoven fabric 10 formed of polyester (PE) long fiber as a waterproof membrane protective material as described above. For convenience, this is the same concept as the water-soluble rubberized asphalt 20 is attached and bonded integrally. For convenience of description, the water-soluble rubberized asphalt 20 or rubberized asphalt is collectively referred to as the protective material-integrated waterproof sheet S, which will be referred to as "protective-integrated asphalt-based waterproof sheet 100" below.

Now, since the present invention relates to a jointing method of the joint between the protective material integrated waterproof sheet and the protective material integrated waterproof sheet will be described with respect to the conventional bonding method for this.

A) Double joint joining method of waterproofing conventional asphalt sheet

In general, the waterproof sheet bonding structure of the conventional sheet waterproofing method is [primer coating → waterproof sheet laying → 10cm layering → ditch lamp heating or welding machine heating bonding] structure.

Asphalt-based double joints are inverted heating joints, so it is difficult to use a generator when the electricity is not supplied to the site because of the use of electricity when fire and indirect heat fans are used.

Most joint joints are pulled out at 20 degrees Celsius. If the joint is poor, asphalt sheet shrinks during the winter temperature drop, causing the joint joint to drop off, making it the biggest defect.

If water penetrates only one of the joints due to a gap in the overlapping process due to the gap occurring in the overlapping waterproof sheet bonding, the internal water flows as soon as it reaches the crack of the structure while driving through the gap. This is one of the biggest problems of lap joints.

B) Butt joint joining method of conventional sheet waterproofing

Conventional butt joint structure (patent patent No. 10-0996660) of the composite sheet film waterproofing method is a structure consisting of (primer coating → waterproof sheet → waterproof sheet butt joint → primary sealant coating → glass fiber → secondary sealant coating. (See Figure 2)

The sealant used at this time is "weight%, purified water 5.0-15.0, emulsifier 0.5-1.0, emulsifier adjuvant 1.0-3.0, styrene-butadiene copolymer resin 15.0-35.0, straight asphalt 40.0-60.0, emulsified asphalt stabilizer 2.0- 4.0, an antifoaming agent composition comprising 0.1-0.5 antifoaming agent and 0.1-0.5 surface tension reducing agent.

The sealant made of such a composition has a long curing curing time, which delays the subsequent work for applying the second sealant after application of the first sealant, and also delays the subsequent process such as backfilling after the application of the second sealant, thereby lengthening the entire air. There is a problem of economic inefficiency due to the long construction period.

C) Tape bonding method of conventional sheet waterproofing

Conventional sheet waterproof tape bonding structure (primer coating-waterproof sheet fitting construction-with high adhesive tape)

High adhesive tape has been developed and supplied, but the price is expensive, there is a problem in the winter season when the joint is dropped due to incomplete bonding and pulled out at 20 degrees Celsius.

D) Bonding method of integrated waterproof asphalt sheet with protective material

Bonding method of the protective material-integrated water-soluble rubberized asphalt waterproof sheet is bonded to the joint portion by the lap joint method as shown in FIG. It is a method of laminating and joining a joint part with a high adhesion primer. Since the water-integrated water-soluble rubberized asphalt waterproof sheet with a protective material has a thickness t, it is inevitable to have a gap as shown in Fig. 3 when it is stacked, and there is a problem of leakage due to the gap, and the high-adhesive primer also loses adhesiveness at 20 ° C There is a problem that the pull is easily eliminated, and the curing time of the high-adhesive primer is long, the subsequent work is not made quickly. As a result, the construction period is long, which is economically inefficient.

⒜ The present invention is a joint bonding method using an unsaturated polyester resin as an adhesive, unlike the lap joint method using a high-adhesive primer, a joint of a protective material-integrated asphalt-based waterproof sheet having a long PE layer as a protective layer. However, due to the properties of unsaturated polyester resin, not only the PE long fiber nonwoven fabric protection layer is easily penetrated, but also the tensile strength due to expansion and contraction of PE long fiber is largely exhibited by mutual coupling between unsaturated polyester resin and PE long fiber. The purpose is to maintain a strong permanent bond without falling off the butt joint, and at the same time to facilitate the joining,

⒝ PE long-fiber non-woven fabric protection material integral asphalt-based waterproof sheets are applied to each other with the primary unsaturated polyester resin applied to each other, and then the glass fiber mesh having a width of about 6 ~ 10cm is applied to the joint to strengthen the tensile strength. Due to the tension due to the expansion and contraction, butt joints do not open or fall off, it is not only harder to bond but also the curing time of unsaturated polyester resin is extremely short (20-30 minutes), so the subsequent process is fast and the entire construction period is efficient. Has a different purpose.

The joints 140 of the protective material-integrated asphalt-based waterproof sheet 100 formed by integrally forming a water-soluble rubberized asphalt 120a waterproof coating film on the PET long fiber nonwoven fabric 110 of the present invention are bonded to each other by an unsaturated polyester resin. The construction method will be described with reference to FIG. 4 as follows.

수용성 coating a water-soluble asphalt primer 130 on the concrete base surface, and after the water-soluble asphalt primer 130 is cured, applying a water-soluble rubberized asphalt 120a thereon to form a coating waterproofing layer on site;

공장 The water-soluble rubberized asphalt (120a) and PE long-fiber nonwoven fabric (110) formed of polyester (PE) long fiber, which is a waterproof film protective material, are integrally anchored and bonded to each other, and manufactured in a factory with a uniform thickness. The long fiber nonwoven fabric 110 has a thickness of 0.57 to 0.60 mm, a weight of 200 to 270 g / m 2, a tension of 35 to 94 kgf / 5 cm in the inclined direction (MD), and a tensile strength of 18 to 39 kgf / 5 cm in the weft direction (CD). Strength, elongation at 48 ~ 53% in the warp direction (MD) and 35 ~ 39% in the weft direction (CD), tear strength of 2.9 ~ 3.5kgf in the warp direction (MD), and 9.5 ~ 21.3kg / Pre-fabricating the protective material integrated asphalt-based waterproof sheet 100 having a bursting strength of m 2 at a factory;

다른 Position the other new protective material-integrated asphalt-based waterproof sheet 100 through the step ⒞ ~ 되게 adjacent to the protective material-integrated asphalt-based waterproof sheet 100 bonded to the site in the step 되 but adjacent joints 140 Engaging each other;

불포화 The unsaturated polyester resin 142 is applied onto the PE long fiber nonwoven fabric 110 with a width of 6 to 10 cm along the butt joint 140, but symmetrically unsaturated with respect to the butt joint. Applying the polyester resin 142 first, and then attaching the fiberglass mesh 144 on the applied unsaturated polyester resin 6 to 10 cm wide before the unsaturated polyester resin 142 is hardened;

(B) applying an unsaturated polyester resin (146) on the secondary after curing the unsaturated polyester resin (142) applied in the first step above;

⒢ the step of bonding the protective material-integrated asphalt waterproof sheet 100 while repeating the step ⒟-⒡: characterized in that it comprises a joint of the waterproof sheet formed asphalt waterproof coating film on the PE long fiber nonwoven fabric 110 ( It is a method of joining 140) and joining by unsaturated polyester resin.

Here, the step of sequentially bonding the protective material-integrated asphalt-based waterproof sheet 100 adjacent to each other while repeating the ⒟-⒢ step; that is, including the ⒣ step waterproof waterproof forming an asphalt-based waterproof coating on the PE long-fiber nonwoven fabric 110 The joint method 140 which abuts the joint part 140 of a sheet | seat, and complete | bonds with a unsaturated polyester resin is completed.

Here, MD stands for Mechanical Direction and refers to the production line direction in which the nonwoven fabric is produced, that is, the longitudinal direction, and CD refers to the perpendicular direction of the MD, that is, the width direction, and stands for Cross Direction.

In addition, since step 와 and step ⒝ can be performed independently of each other, the application of any of step 와 and step 먼저 first does not cause any problem. Therefore, step → step is the same configuration as step → step.

In particular, the PE long-fiber nonwoven fabric 110 of the protective material-integrated asphalt-based waterproof sheet 100, PE non-woven fabric 110, as well as the PE non-woven fabric 110 should not be detached from the wall by the soil weight at the time of refilling, as well as PE non-woven fabric by reinforcement Since (110) must not be torn or damaged, it must have at least the physical properties shown in Table-1.

Therefore, the PE long fiber nonwoven fabric 110 has a thickness of 0.57-0.60 mm, a weight of 200-270 g / m 2, 35-94 kgf / 5 cm in the inclined direction (MD), and 18-39 kgf / 5 cm in the weft direction (CD). Tensile strength, elongation at 48 ~ 53% in the warp direction (MD) and 35 ~ 39% in the weft direction (CD), tear strength of 2.9 ~ 3.5kgf in the warp direction (MD), and 9.5 ~ 21.3 It has a bursting strength of kg / m 2.

PE long fiber nonwoven fabric 110 has a thickness of 0.57-0.60 mm, a weight of 200-270 g / m 2, 35-94 kgf / 5 cm in the inclined direction (MD), and 18-39 kgf / 5 cm in the weft direction (CD). Tensile strength, elongation at 48 ~ 53% in the warp direction (MD) and 35 ~ 39% in the weft direction (CD), tear strength of 2.9 ~ 3.5kgf in the warp direction (MD), and 9.5 ~ 21.3kg The results of the experiment under the condition of having a bursting strength of / ㎡ are shown in Table-1.

Table-1.

Figure pat00001

At tear strength of 2.9 ~ 3.5kgf and rupture strength of 9.5 ~ 21.3kg / ㎡, the long fibers of PE nonwoven fabric 110 are anchored firmly with water-soluble rubberized asphalt 120a film waterproofing agent, so that when the soil is refilled The protective material of the PE nonwoven fabric 110 is adhered to and adhered to the wall structure by soil weight so that the PE nonwoven fabric 110 is not torn or damaged by the reinforcement.

If the tear strength and burst strength are in the range below it, the PE long fiber nonwoven fabric 110 is torn or damaged, and if it is more than that, the thickness becomes thick and uneconomical.

The shape of the PE long fiber nonwoven fabric 110 is not the same, but the same shape in that the woven thickness is constant.

PE long fiber nonwoven fabric 110 is a material of high strength and stable form, heat resistance, cold resistance and wear resistance and durability.

As a protective material-integrated asphalt-based waterproof sheet 100 formed of a PE long-fiber nonwoven fabric 110 as a protective layer, the thickness is constant and excellent in quality because it is manufactured in a factory.

Protective material integrated asphalt-based waterproof sheet 100 is a structure in which the water-soluble rubberized asphalt (120a) or rubberized asphalt (120b) is bonded to the PE long fiber nonwoven fabric (110).

The tear strength and bursting strength of the PE long fiber nonwoven fabric 110 of the protective material-integrated asphalt-based waterproof sheet 100 are not only in the above range, but also the PE long fiber nonwoven fabric 110 and the water-soluble rubberized asphalt 120a or The adhesion with rubberized asphalt 120b is very good. Unlike the water-soluble rubberized asphalt 120a, the rubberized asphalt 120b has excellent adhesiveness and is not water-soluble, and thus has no advantage in curing. As soon as the water-soluble rubberized asphalt 120a of the concrete base surface applied to the site is cured, adhesion of the rubberized asphalt 120b of the waterproofing-integrated asphalt-based waterproof sheet 100 to the water-soluble rubberized asphalt 120a of the concrete base surface immediately. Since this is possible there is an advantage that the subsequent process is made quickly.

Protective material-integrated asphalt-based waterproof sheet 100 of the present invention is mass produced in advance in the factory, in the field as shown in Figure 2 after applying the primer 130 on the concrete base surface (that is, the outer wall of the building) and then on the primer 130 When the water-soluble rubberized asphalt 120a is coated and cured and cured, the rubberized asphalt 120b of the protective material-integrated asphalt-based waterproof sheet 100 is adhered to the cured and cured water-soluble rubberized asphalt 120a as it is. Therefore, the adhesive work is easy and quick, there is an advantage that the input of subsequent processes such as reinforcement and backfill is made quickly without delay.

On the other hand, the waterproof sheet is usually jointed with each other because of its size limitation. Asphalt-based waterproof sheet integrated with a protective material is no exception.

Protective material-integrated asphalt-based waterproof sheet 100 has a thickness t because the water-soluble rubberized asphalt (120a) or rubberized asphalt (120b) and PE long-fiber nonwoven fabric (110) integrally manufactured in a factory at a uniform thickness. The thickness t is usually about 1.5 ~ 2mm. If the protective material-integrated asphalt-based waterproof sheet 100 is laminated in a jointed manner, a gap is generated due to the thickness t, which causes leakage, and because of the adhesion of the primer 130, the joint part is easily in the winter season of 20 degrees Celsius. There is a problem of dropping out.

The joint of the protection material integrated asphalt-based waterproof sheet 100 having a thickness t is suitable. In the state of backing the joint 140 of the protective material-integrated asphalt-based waterproof sheet 100, the unsaturated polyester resin 142 is first applied on the PE long fiber nonwoven fabric 110 to 6-10 cm in width (d), and then hardened. It is impregnated with a fiberglass mesh 144 laid on a width of 6 ~ 10cm. The glass fiber mesh 144 may also be laid while second and third coating of the unsaturated polyester resin 146 on it again. Tensile strength of the joint 140 is reinforced by the glass fiber mesh 144 so that the durability and robustness of the joint 140 are semi-permanently maintained.

In addition, the unsaturated polyester resin is very short curing time (20-30 minutes), the subsequent process is rapidly followed by the overall construction period is shortened and efficient as well as excellent adhesion to the PE long fiber nonwoven fabric (110).

아스팔트 Asphalt-based waterproof sheet of the present invention is mass produced in advance in the factory, and in the field, the primer is applied to the outer wall of the building, and then the water-soluble rubberized asphalt is applied on the primer, and the cured and cured water-soluble rubberized asphalt. Since the rubberized asphalt of the asphalt-based waterproof sheet only needs to be attached and adhered to each other, the adhesive work is easy and quick, and there is an effect that the subsequent processes such as reinforcing bar and backfilling are performed quickly without delay.

⒝ The present invention is a joint bonding method using an unsaturated polyester resin as an adhesive, unlike the lap joint method using a high-adhesive primer, a joint of a protective material-integrated asphalt-based waterproof sheet having a long PE layer as a protective layer. Due to the characteristics of unsaturated polyester resin, not only the PE long fiber nonwoven protective layer is easily penetrated, but also the tensile strength of the long stretched PE fiber is greatly exerted by mutual coupling between the unsaturated polyester resin and PE long fiber. Since the butt joints are maintained without falling off, there is an effect that the bonding is easy to be maintained at the same time.

⒞ PE-fiber non-woven fabric protective material integral asphalt-based waterproof sheets are applied to each other with the primary unsaturated polyester resin applied to each other, and then the fiberglass mesh having a width of about 6 ~ 10cm is laid on the joint to strengthen the tensile strength, 2 As it is coated with unsaturated polyester resin, the joint is not opened or dropped due to stretching due to the temperature change, so that the adhesion is more firm and the curing time of the unsaturated polyester resin is extremely short (20-30 minutes). As the process continues quickly, the overall construction period is shortened.

맞 Since the butt joint method of the present invention can be joined while visually confirming the joint joint unlike the joint joint method, there is an effect that the joint joint is reliably joined.

완전한 Perfect bonding of the joints of sheets is necessary because the width of the waterproof sheet is on average 100cm, and 1m of joints occur per 1㎡ of waterproof area. It is practically impossible to join the master while verifying the state of joining skilled workers. By the way, unsaturated polyester is transparent, so that the joint can be visually confirmed immediately, there is an advantage that additional coating is possible when the bonding is not perfect.

아스팔트 Most asphalt-based waterproof sheets are almost eliminated when the joints are pulled out at 20 ° C. and 80 ° C., whereas the asphalt long-sheet non-woven protective material integral asphalt-based waterproof sheets of the present invention are bonded to each other at −20 ° C. At 80 ° C or at 80 ° C, there is an advantage that does not drop out.

맞 There is a method of joining butt joints between sheets using water-soluble rubberized asphalt and glass fiber mesh. However, water-soluble rubberized asphalt has a long hardening time and flows down to the vertical part, so that waterproof work is not performed properly. Due to the difficulty in the work and the need for re-installation in contact with water prior to curing, the construction is affected by various climate effects, which enables vertical wall joining with short curing times.

맞 Butt joints using watertight sheets and adhesive tapes with excellent adhesive strength, but adhesion failure occurs when temperature drops and drops at 20 degrees Celsius, and the price of tapes is high, whereas the butt joints of the present invention are inexpensive. And permanent bonding is possible.

⒤ In case of waterproofing of the sheet, there are many cases of damage to the sheet. Generally, the sheet being used is cut and partly repaired by inverting or using a hot air blower. In this case, even after a long period of time can be eliminated.
