Description

Waterproofing sheet with protective oil-soluble rubber asphalt in a body and method constructing the complex waterproof sheets kind with recycling release polyethylene film of waste disposal}

The present invention relates to a composite waterproofing method in which the protective material-integrated rubberized asphalt waterproof sheet and the disposed release film are attached and recycled to the back of the protective material-integrated rubberized asphalt waterproof sheet. By curing and curing in advance to factory production, the curing time of water-soluble rubberized asphalt film waterproofing agent in field work can be shortened, and at the same time, it is possible to improve productivity by machine automation by using oil-based asphalt for the factory-integrated waterproof sheet. By improving the efficiency, construction efficiency and economical construction are achieved.

In addition, the oil-based rubberized asphalt coating waterproofing agent and the PE long-fiber nonwoven fabric are produced by mechanically manufacturing the oil-based rubberized asphalt coating waterproofing agent and the waterproofing film protective material (that is, the nonwoven fabric made of polyester (PE) long fiber). It is economical and construction quality is improved by uniformly manufacturing the thickness of the waterproof sheet in which the protective material is integrally formed while anchoring and binding each other.

In particular, after the release film attached to the adhesive oil-based rubber asphalt surface of the protective material-integrated waterproof sheet is constructed and the protective material-integrated waterproof sheet is applied to the structure, the release film is peeled off the back of the protective material-integrated waterproof sheet [ie, PE long fiber nonwoven fabric]. By displacing the release film that is disposed of and by refilling, it protects the integrated waterproof sheet from damage from soil and stone when it is refilled, and between the integrated waterproof sheet and the soil cover in the process of consolidation and settlement of the backfilled soil of the vertical wall. By the sliding action of the release film located in the frictional force on the protective material integrated waterproof sheet is reduced, thereby preventing the breakage of the protective material integrated waterproof sheet.

A) Waterproof structure of conventional film waterproofing method

 (6) The waterproof structure of the conventional coating waterproofing method is the structure [concrete base surface → water-soluble rubberized asphalt coating waterproofing agent (A) coating and curing → adhesive (B) → protective material (protective motor, home board, styrofoam) (C)]. See Figure 1)

  ① As shown in Fig. 1, the coating and curing of the water-soluble rubberized asphalt coating waterproofing agent (A) is a work performed in the field by three to five repetitive works.

② In other words, the water-soluble rubberized asphalt film waterproofing agent (A) is applied once and cured, and then applied again and cured again. There is a problem that the input of the subsequent process is not made quickly because it has to wait until it is.

도 In general, the coating film waterproofing agent (A) refers to a composition in which an aqueous or oily liquid form waterproofing agent is applied to a surface to obtain a waterproofing effect using the remaining film after evaporation of water or a solvent. Coating waterproofing agent (A) is mainly used for external waterproofing of construction and civil engineering structures, waterproofing of floors, walls and ceilings of underground structures, and indoor waterproofing of toilets, bathrooms, verandas, and the like.

 ⒞ Rubberized asphalt coating waterproofing agent is classified into water-soluble and oil-based.

Oil-based rubberized asphalt coating waterproofing agent has been pointed out that toluene, which is used as a solvent, may cause environmental pollution. have. The oily rubberized asphalt system is melted at 120 ° C or higher. In the unheated state, it is semi-solid, and in the molten state, it is gel. Semi-solid or gel surfaces have good adhesion.

⒟ Water-soluble rubberized asphalt-based waterproofing agent is generally used even when the water content on the surface of the coating material has a high workability, so water-soluble rubberized asphalt-based waterproofing agent is generally used.

형성 To form a waterproof coating using the water-soluble rubberized asphalt coating waterproofing agent (A), first, by applying a water-soluble rubberized asphalt coating waterproofing agent (A) using a brush, roller or spray to the place where the waterproofing coating film is to be formed. A coating film is formed. Subsequently, the water contained in the water-soluble rubberized asphalt coating waterproofing agent (A) is naturally dried to form a waterproof coating.

 ⒡ Despite the advantages of the water-soluble rubberized asphalt coating waterproofing agent (A) in this way it is a liquid, it must be applied several times in order to have a certain thickness of the waterproof layer.

When applied thickly, the surface is cured and cured first, thereby blocking the evaporation of water, which delays curing and curing time several times. In order to prevent this, the application is usually repeated three to five times shallow, but even if this does not have the disadvantage that it takes more than 24 hours curing and curing time.

  ① It takes about 8 hours and water for one time of coating to form waterproof coating and 24 hours for complete drying and hardening for three times of repeated coating.

  ② There is a problem that the construction period is delayed due to delay in the subsequent process due to the delay of curing time.

  ③ For example, the basement of the building first performs the bottom waterproofing work after curing the foundation concrete, and then reinforces the steel after the protection mortar or reconstruction.

  ④ In particular, when the water-soluble rubberized asphalt waterproofing agent (A) is rained within 3 to 6 hours (curing time) after construction, the waterproofing agent is dissolved in water, causing trouble of re-installation due to breakage of the waterproofing layer. In addition, when the temperature decreases, the hardening time is longer because evaporation of moisture is difficult.

When applied thick at once, surface hardening occurs first, and the curing time is much longer. Therefore, it is difficult to apply because there are problems depending on temperature and climatic conditions such as three to five repetitive constructions to maintain a constant thickness.

  ⑤ When the number of times of coating curing increases, it usually takes 2 ~ 3 days of curing time.

⑥ Water-soluble asphalt coating waterproofing agent is a thermoplastic coating film whose drying rate is determined according to the rate of evaporation of water. Especially, in case of construction site with high humidity or low temperature, poor drying occurs. This causes the surface or internal drying to form a waterproof coating film, such as a drop in physical properties such as water resistance and strength of the waterproofing agent. In addition, when the surface and internal drying for forming the waterproof film is delayed, it is a problem that is most likely to delay construction.

B) Problems due to the liquid phase of water-soluble asphalt coating waterproofing agent in the conventional film waterproofing method

수용성 Since the water-soluble asphalt-based coating waterproofing agent is a liquid phase in the conventional coating film waterproofing method, when it is applied to a horizontal surface such as a roof, there is a problem of being unable to secure a waterproof layer having a uniform thickness due to the influence of gradient and irregularities.

In the case of the gradient, the thickness of the coating waterproof material becomes thicker at the lower part, while the thickness of the coating waterproof material becomes thinner at the higher part. Since the thickness of the waterproof layer is uniformly applied and the coating layer is designed to be waterproof, the thickness of the waterproof layer is thick due to the gradient, and when the thickness becomes thin, there is a problem that the thin portion does not reach the design thickness.

⒞ In addition, since the thickness of the coating waterproofing is thickened in a low gradient, the cost of the expensive coating waterproofing is also increased, which is uneconomical and the curing time is long.

⒟ In the case of rooftop waterproofing, it is given a constant one-way gradient to smooth rainwater drainage.

⒠ Uneven flexion is different from the gradient only that there are a large number of large and small irregularities, the effect of the coating waterproofing on the in and out portion is the same as the gradient and the problem due to the thin and thick of the waterproof thickness.

C) Problems with the pinholes in the film structure of the conventional film waterproofing method

Hole The pin hole is a small through hole in the film waterproof layer formed by the expansion of the air due to the temperature rise when small air remains in the film waterproof layer. Since the pinhole penetrates the waterproof layer or makes the thickness of the waterproof layer thin, there is a problem that the waterproof function is not properly achieved.

도 The coating structure of the conventional coating waterproofing method has a problem in that the waterproofing of the coating film reduces the waterproof function since there is no means to suppress the swelling of the pinhole formed in the coating waterproofing layer.

⒞ According to the specification, the waterproofing agent is required to be evenly applied with a brush, rubber spatula, or a spraying device to prevent pin holes.

 무수 Innumerable small fine surface pores are formed in irregular shape on concrete surface.

  ① Air is released into the atmosphere through the concrete surface pores due to the hydration in the concrete.

  ② In the state where the hardened film waterproof layer is closed the concrete surface pores, the released air is collected in the concrete surface irregularities, and the collected air is moved to the low pressure irregularities.

③ The uneven air pressure inflates the waterproofing layer and makes the inside of the cavity a pinhole.

D) Problems of waterproofing membrane protective material in coating structure of conventional coating waterproofing method

(3) In the coating structure of the conventional coating waterproofing method, the waterproofing film protective material is adhered onto the coated and cured water-soluble rubberized asphalt coating waterproofing agent.

⒝ Waterproof membrane protective material used at this time is protective mortar, styrofoam, home board.

 (3) The bonding of the cured water-soluble rubberized asphalt waterproofing agent to the waterproofing protective film is by adhesive.

  Water-soluble rubberized asphalt coating waterproofing agent, and styrofoam, home board is a material that does not adhere well to each other, the strength of the adhesion is the biggest disadvantage.

The surface of the water-soluble rubberized asphalt film waterproofing agent is formed on the surface of the water-soluble rubberized asphalt film waterproofing agent because only the water-soluble rubberized asphalt film waterproofing agent adheres to the surface of the styrofoam and the home board. Even if there is a little moisture in the adhesive strength is weak, the protective material by the adhesive of the prior art is being eliminated even by blowing the wind.

⒟ Waterproofing membrane protective material is a protective material that is attached to prevent the dropping and damage of water-soluble rubberized asphalt coating waterproofing during reinforcing reinforcement work or refilling of soil after finishing waterproofing work under the building underground.

수용성 When reinforcing bar works, water-soluble rubberized asphalt film waterproofing agent gets stuck on reinforcing bars and damages the film waterproofing agent, and waterproof film protective material attached on the surface of water-soluble rubberized asphalt film waterproofing agent of vertical wall is pushed by soil pressure. Or dropping out.

E) The invention is a further improvement of the preliminary application.

The protective material-integrated waterproof sheet of the pre-applied invention has a structure in which the water-retaining rubberized asphalt coating waterproofing agent 20 and the PE long-fiber nonwoven fabric 10 formed of polyester (PE) long fiber, which is a waterproofing protective film, are integrally anchored and bonded to each other. to be. As water-soluble rubberized asphalt is liquid, curing and curing time are required, and mechanical automation production is difficult, resulting in low productivity. In the protective material-integrated waterproof sheet structure of the pre-applied invention, by using oily rubberized asphalt instead of water-soluble rubberized asphalt, productivity by mechanical automation is improved.

⒜ The present invention has the characteristics of oil-based rubberized asphalt as it is divided into on-site work and factory production work to cure and harden in advance to shorten the drying curing time of water-soluble rubberized asphalt film waterproofing agent in the field work, and at the same time integrated protection material of factory production Its purpose is to improve the efficiency of productivity by mechanical automation by using oil-based rubberized asphalt for waterproof production and construction.

(2) Oily rubberized asphalt coating waterproofing agent and waterproofing film protective material (ie, nonwoven fabric made of polyester (PE) long fiber) are manufactured and manufactured integrally by mechanization. The other purpose is to make the thickness of the waterproof sheet formed integrally with the protective material while anchoring and binding to each other,

목적 Another purpose is to reduce the drying curing time of oil-based rubberized asphalt film waterproofing agent by dividing into field work and factory production work so that subsequent process input can be carried out without delay.

다른 It is another purpose to suppress the swelling of the pin hole by PE long fiber nonwoven fabric which is a waterproof film protective material integrally formed with oily rubberized asphalt coating waterproofing agent.

점착 Adhesive oil-based rubber sheet of protective material integrated waterproof sheet Remove the release film attached to the asphalt surface and install the protective material integrated waterproof sheet on the structure, and then remove the release film removed from the back of the protective material integrated waterproof sheet (ie PE long fiber nonwoven fabric). By attaching and recycling the release film that is disposed of, the protection sheet integral waterproof sheet is not only protected from soil and stone damage when it is refilled, but also between the waterproof sheet and the soil integrated sheet. Another object of the present invention is to prevent breakage of the protective material-integrated waterproof sheet by reducing the frictional force on the protective material-integrated waterproof sheet by sliding the positioned release film.

The present invention provides a uniform thickness while anchoring and binding the PE long fiber nonwoven fabric 10 formed of polyester (PE) long fiber and the rubberized asphalt 20 heated to 120 ° C. to 140 ° C. integrally with each other. Furnace protection material integrated rubberized asphalt waterproof sheet 100, but the rubberized asphalt 20 is 55 to 75 parts by weight asphalt, 8 to 15 parts by weight of styrene butadiene styrene synthetic rubber, 4 to 20 parts by weight of process oil, It is composed of 3 to 10 parts by weight of thermoplastic resin, 10 to 30 parts by weight of inorganic filler, and the PE long fiber nonwoven fabric 10 has a thickness of 0.57 to 0.60 mm, a weight of 200 to 270 g / m 2, and 35 to 94 kgf / in the MD direction. Protective material-integrated rubberized asphalt waterproof sheet, characterized in that it has a tensile strength of 5cm and 18 ~ 39kgf / 5cm in the CD direction, and an elongation of 48 ~ 58% in the MD direction and 35 ~ 39% in the CD direction.

In this case, the MD direction is an abbreviation of Mechanical Direction, and refers to a production line direction in which a nonwoven fabric is produced, that is, a longitudinal direction, and the CD direction is an abbreviation of a cross direction. In addition, since the oily rubberized asphalt is commonly referred to as rubberized asphalt 20, the rubberized asphalt 20 will be used synonymously with oily rubberized asphalt.

In addition, the release film 30 of HDPE (High Density Poly Ethylene) material having a thickness of 0.04 to 0.06 mm is attached to the surface of the rubberized asphalt 20.

Release film 30 is removed from the protective material integrated waterproof sheet 100 is usually disposed of.

Even if the disposal is to be disposed, the amount of the release film 30 is large and its area is large, so the volume is difficult to handle.

In particular, after the release film 30 attached to the adhesive rubberized asphalt surface of the protective material integrated waterproof sheet to construct a protective material integrated waterproof sheet on the structure, and peeled off the back of the protective material integrated waterproof sheet (that is, PE long-fiber nonwoven fabric) When the release film 30 is attached, the release film 30 is immediately recycled at the construction site and recycled, thereby making it an environmentally friendly construction in which treatment costs due to transportation, incineration, and labor costs are reduced.

Not only that, the protective film-integrated waterproof sheet is further protected from damage caused by soil and stone when backfilled by the release film 30.

In particular, in the case of the vertical wall, the backfilled soil is consolidated and settled. Protective material integrated waterproof sheet 100 is firmly fixed at the top of the vertical wall. The upper fixing is to prevent the protective material integrated waterproof sheet 100 to flow down. When the backfilled soil is consolidated and settled, the frictional force of the soil against the protective material-integrated waterproof sheet 100 acts.

When the protective material integrated waterproof sheet 100 is directly fixed to the top, when frictional force due to consolidation and settlement of soil is directly applied to the protective material integrated waterproof sheet 100, the protective material integrated waterproof sheet 100 generates tensile force due to the lower pulling. It will tear in the middle.

The release film 30 is interposed between the protective material integrated waterproof sheet 100 and the earth and sand so that the frictional force due to consolidation and settlement of the soil is not directly caught by the protective material integrated waterproof sheet 100.

By the sliding action of the release film 30 interposed between the protective material-integrated waterproof sheet 100 and the earth and sand, the frictional force due to consolidation and settlement of the soil is not caught by the protective material-integrated waterproof sheet 100.

At this time, the material of the recycled release film 30 is suitable for HDPE, the thickness is preferably 0.04 ~ 0.06mm.

In addition, the protective material integrated rubberized asphalt waterproof sheet 100 is continuously manufactured in the factory. The protective material-integrated rubberized asphalt waterproof sheet 100 produced in this way is wound on a roll for storage and transportation.

Silicone is spray-coated on the back surface of the release film 30 wound on a roll.

This is to prevent the release films 30 on the rolls which are wound on each other from sticking to each other.

Now, the physical properties of the PE long fiber nonwoven fabric 10 used in the present invention will be described.

PE long fiber nonwoven fabric 10 has a thickness of 0.57 ~ 0.60mm, its weight is 200 ~ 270g / ㎡, tensile strength is 35 ~ 94kgf / 5cm in the MD direction, has a 18 ~ 39kgf / 5cm in the CD direction , And the elongation is 48 ~ 58% in the MD direction, 35 ~ 39% in the direction of the CD experiment results are shown in Table-1.

Table-1.

According to Table 1, it can be seen that it has a tear strength of 2.9 to 3.5 kgf and a bursting strength of 9.5 to 21.3 kg / m2 in the MD direction.

At tear strength of 2.9 ~ 3.5kgf and rupture strength of 9.5 ~ 21.3kg / ㎡, long fibers of PE nonwoven fabric are anchored and bound firmly with rubberized asphalt (20). The protective material of the PE nonwoven fabric is adhered to and adhered to the wall structure so that it does not push or sag and is attached as it is, and the PE nonwoven fabric is not torn or damaged by reinforcement.

If the tear strength and burst strength are in the range below that, the PE long fiber nonwoven fabric 10 is torn or damaged, and if it is more than that, the thickness becomes thick and uneconomical.

Although the shape of the PE long fiber nonwoven fabric 10 is not woven, it is the same in that the woven thickness is constant.

PE long fiber nonwoven fabric 10 is a material of high strength and stable form, heat resistance, cold resistance and wear resistance and durability.

Protective material integrated waterproof sheet 100 has the advantage that the thickness is constant and excellent quality because it is produced by the machine automation in the factory. Since the rubberized asphalt 20 is a gel phase, it is possible and easy to manufacture machine automation.

The tear strength and burst strength of the PE long fiber nonwoven fabric 10 of the protective material-integrated waterproof sheet 100 not only fall within the above ranges, but also the rubberized asphalt 20 penetrates the PE long fiber nonwoven fabric 10 so that it is anchored and bonded. In this case, the swelling of the pinholes is suppressed.

The protective material-integrated waterproof sheet 100 of the present invention is manufactured in a state of curing and hardening in a factory in advance, and in the field, it is applied to the exterior wall of the building in advance in order of the primer 60 and the water-soluble rubberized asphalt 50. After curing and curing the water-soluble rubberized asphalt 50, the factory-made protective material-integrated waterproof sheet 100 having the release film 30 removed on the water-soluble rubberized asphalt 50 film is bonded and constructed. Unlike the conventional waterproof structure, in which a series of processes are performed sequentially after curing, curing and curing are carried out in the factory and on site beforehand, so that subsequent processes such as reinforcement and refilling due to curing and curing are not delayed. There is an advantage that is made.

⒜ The present invention shortens the drying curing time of the water-soluble rubberized asphalt film waterproofing agent by constructing it into field work and factory manufacturing work, and also uses rubberized asphalt as a protective material integrated waterproof sheet to make the machine automation factory and production possible. Therefore, it can be installed quickly without delay time due to curing and curing, so that the construction is not only efficient and economical with air shortening, but also without delay in the subsequent process.

⒝ As the thickness of the waterproof sheet integrated with the protective material is uniform, it is not affected by the gradient or irregularities of the waterproof surface.

뿐만 The tear strength and rupture strength of the PE long fiber nonwoven fabric of the protective material integrated waterproof sheet is not only large, but also the water-soluble rubberized asphalt film waterproofing agent penetrates the PE long fiber nonwoven fabric and is anchored and anchored, thereby preventing swelling of the pinhole. There is an effect that the water-soluble rubberized asphalt coating waterproof layer is excellent in quality.

⒟ In particular, after the release film attached to the adhesive rubberized asphalt surface of the protective material-integrated waterproof sheet is constructed and the protective material-integrated waterproof sheet is applied to the structure, the release film is removed from the back of the protective material-integrated waterproof sheet (ie, PE long fiber nonwoven fabric). As it protects the integrated waterproof sheet from protection of soil and stone during backfilling, the release film that is disposed of is recycled at the construction site and recycled and recycled, thereby reducing the processing cost due to transportation, incineration and labor costs. Is a useful invention.

It is possible that construction is not only efficient and economical with air shortening, but also without delay in the subsequent process.

Here, step ⒜ and step 가능 can be performed independently of each other. If any of the first step and the first step is performed first, there is no problem in the application. Therefore, step → step is the same configuration as step → step.

In addition, the material of the release film 30 removed in step PE is HDPE (high density polyethylene resin), the thickness is 0.04 ~ 0.06mm, the peeled release film 30 is PE with the protective material integrated waterproof sheet It is attached to the surface of the long fiber nonwoven fabric 10 and immediately recycled in the field, thereby making it environmentally friendly and economical because it is easy to process the release film 30.

On the other hand, when the protective material integrated waterproof sheet is applied to the waterproof waterproof, after the step (d) it is also preferable to apply an acrylic resin to the upper portion of the protective material integrated waterproof sheet 100.
