2 is a sectional view of a waterproof member.
3 is a cross-sectional view of the waterproof member in use;
4 is a plan view of a waterproof member.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, the drain hole waterproofing member according to the present invention includes a cylindrical main body 110 formed to be inserted into a drain hole 2 of a building, and a main body 110 that is supported by an edge of the drain hole 2 of the building 110); a drain insertion tube (100) having an annular support portion (120) extending outwardly from an upper edge of the drainage tube insertion tube (100); A butyl rubber adhesive layer 200 formed on the upper surface of the supporting part 120 and extending outwardly; And an outer protective portion 300 provided to cover the upper surface of the butyl rubber adhesive layer 200.

That is, the joining structure of the drain hole insertion pipe 100, the butyl rubber adhesive layer 200 and the outer protecting part 300 is manufactured in the factory in advance and is installed in the drainage hole 2 of the slab concrete, 3).

In this waterproof structure, the gap between the slab concrete and the drain hole is completely closed with the combination structure of the ring-shaped support 120, the butyl rubber adhesive layer 200 and the outer protection part 300 of the drain hole insertion pipe 100, Since the waterproofing material 3 is applied, it is possible to stably prevent permeation of water into the gap between the slab concrete and the drain hole.

When the releasing paper 400 is installed to cover the bottom surface of the butyl rubber adhesive layer 200, it is easy to carry and store the paper. When the releasing paper 400 is removed during the construction, a butyl rubber adhesive layer 200 is formed on the upper surface of the concrete Can be attached.

The main body 110 and the support portion 120 of the drain hole insertion tube 100 are circular in vertical section and the butyl rubber adhesive layer 200 and the outer protective portion 300 have a circular cross- The drain hole insertion tube 100 can be easily installed in the tubular structure, and the butyl rubber adhesive layer 200 and the outer protective portion 300 of the square structure can easily be combined with other waterproof members having a square structure (FIG. 4) .

As the outer protective portion 300, a release paper or a film made of a synthetic resin material or a nonwoven fabric is used.

It is possible to firmly bond the butyl rubber adhesive layer 200 and the waterproofing material 3 when the releasing paper is provided as the outer protective portion 300 so as to cover the upper surface of the butyl rubber adhesive layer 200 and separated at the time of installation have.

The film is formed by mixing one or more of a polyethylene (PE), a polypropylene (PP), an ethylene vinyl acetate (EVA), a polyvinyl chloride (PVC), a thermoplastic polyolefin (TPO) It is preferable to use a material.

As the nonwoven fabric, it is preferable to use a material formed by mixing one or more of polyethylene, polypropylene, polyester, and viscose rayon.

Hereinafter, an embodiment of the butyl rubber composition for forming the butyl rubber adhesive layer 101 will be described.

The butyl rubber composition comprises 5 to 30 wt% of butyl rubber, 10 to 60 wt% of an inorganic filler, 15 to 45 wt% of a tackifier, 2 to 15 wt% of a modifier, 0.1 to 10 wt% of a pigment and 0.1 to 5 wt% .

[0003] Butyl rubber is a kind of synthetic rubber produced by a factory in general use, and is a rubber material excellent in adhesiveness and excellent in heat resistance and cold resistance. There are various grades of butyl rubber, but the grade is not limited in the present invention.

When the content of the butyl component is less than 5% by weight, the amount of the butyl component is too small to reduce the physical properties such as elasticity and elongation, and the filling characteristics peculiar to the butyl rubber are not sufficiently exhibited. It becomes more than necessary and price competitiveness is lowered.

The inorganic filler may be selected from the group consisting of calcium carbonate, talc, silica, mica, clay, fly ash and bentonite.

When the inorganic filler component is less than 10% by weight, the compressive strength of the product is lowered. When the inorganic filler component is more than 60% by weight, the amount of the filler component is too much, which is a factor to detract from the physical properties such as elasticity, elongation and adhesion strength.

The tackifier may be selected from the group consisting of petroleum resin, polybutene, rosin (rosin) and rosin ester, or a combination of two or more thereof.

As the petroleum resin, C5 series, C9 series, copolymer resin, hydrogenated resin, etc. may be used, either alone or in combination of two or more.

There are several grades of polybutene, but the grades of the polybutene are not limited in the present invention.

When the tackifier is less than 15% by weight, the function as a pressure-sensitive adhesive is deteriorated. When the tackifier is more than 45% by weight, the price competitiveness is lowered by the use of the tackifier more than necessary.

The modifier may be selected from the group consisting of natural rubber (NR), SBS rubber, chloroprene rubber (CR), EPDM rubber, SBR, ethylene vinyl acetate (EVA), ATA polypropylene (APP) , Amorphous polyolefin (APAO), polyethylene (PE), and polypropylene (PP) can be used in combination.

If the amount of the modifier is less than 2% by weight, the amount of the modifier is too small to be used, and if it exceeds 15% by weight, the amount of the modifier is excessively large.

The pigment is preferably formed by one of an inorganic pigment, an organic pigment for each color, or a mixture thereof.

The inorganic pigment is preferably formed by mixing one or two or more of carbon black, titanium dioxide (white), red iron oxide, yellow iron oxide and iron oxide.

However, pigments containing heavy metals such as lead, mercury and chromium should not be used.

If the amount is less than 0.1% by weight, the amount of use is too small to expect a desired color product. If the amount is more than 10% by weight, the use of excessively lowers the price competitiveness.

Additives include heat stabilizers, ultraviolet stabilizers, brighteners, lubricants and the like, and they are not limited in their kind because they are commonly used.

Its usage is 0.1 ~ 5% by weight.

The butyl rubber composition thus obtained not only has excellent adhesion and adhesion, but is also excellent in ease of installation, durability and waterproof performance, and further improves adhesion performance, water tightness and crack filling performance.

Table 1 shows three examples relating to the compounding ratio of the butyl rubber composition constituting the butyl rubber adhesive layer of the waterproof member according to the present invention, and Table 2 shows the experimental results on the physical properties of the above examples.

As shown in Table 2, all three examples were proved to exhibit excellent physical properties in comparison with the comparative examples.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
