The coating-sheet composite waterproofing material 10 according to the present invention is composed of a coating film waterproofing reinforcement layer 11, an asphalt waterproofing layer 12, a reinforcing nonwoven fabric layer 13, and a silica sand layer 14 as shown in FIG. 1.

The coating film waterproofing reinforcing material layer 11 is a structure in which the color finish coating waterproofing material 21 and the sheet waterproofing material 22 are apply | coated and impregnated in polyester long fiber 23 (or short fiber) like FIG.

이고 견고한 구조 형성을 위해 니들 펀칭 처리된 것이 바람직하다.At this time, the polyester-based long fiber 23 has a weight of 100 ~ 140

And needle punched to form a rigid structure.

In addition, the color finish coating waterproofing material 21 is a cement polymer mixed coating material in which EVA, VAE, Acryl, Acryl-Styrener emulsion and aerosol powder composition are formed by mixing alumina cement and powder of silica sand, and an acrylic one-component type room temperature curing color coating material thereon. Is treated as.

At this time, the acrylic one-component room temperature curing color coating material is made of a Styrene-Acryl emulsion (Tg; -13 ℃, solid content 48 ± 1%), inorganic pigments, calcium carbonate.

The asphalt waterproof layer 12 may be selected from an improved asphalt compound improved with a polymer such as synthetic resin APP (Atactic Polypropylen), synthetic rubber SBS (Styrene Butadiene Styrene), rubberized asphalt compound using synthetic rubber, water-soluble rubber asphalt compound. .

The reinforcing nonwoven fabric layer 13 is a reinforcing layer formed by attaching a nonwoven fabric in a lengthwise direction to an exposed surface of the asphalt waterproofing layer 12. At this time, the nonwoven fabric is attached to the surface of the asphalt waterproof layer 12 through a pressing process.

At this time, the reinforcing nonwoven fabric layer 13 is for the damage and deformation stability of the exposed portion of the asphalt waterproof layer 12. That is, the reinforcing nonwoven fabric layer 13 is prevented from being damaged by bending, bending or folding during handling due to the adhesiveness of the asphalt.

을 적용함이 바람직하다.In this embodiment, the nonwoven fabric is a short fiber polyester nonwoven fabric having a width of about 100 to 250 mm and is 30 to 100.

In order to prevent sheet deformation due to tension unevenness during manufacturing, 50 ~ 70

It is preferable to apply.

The silica sand layer 14 is formed by spraying silica on the remaining portion of the asphalt waterproof layer 12 except for the reinforcing nonwoven fabric layer 13. The particle size of silica sand in this example was set to 200 ~ 450㎛.

On the other hand, when the asphalt asphalt waterproof layer 12 is configured by extruding the improved asphalt in the present invention can be configured to be flat as shown in FIG.

That is, the one-way wing portion of the coating waterproof reinforcement layer 11 is exposed to 15 to 50 mm, and the asphalt waterproof layer 12 is formed to be exposed to about 30 to 50 mm in the other direction.

In particular, the non-woven fabric having a width of 100 to 250 mm in the lower portion of the exposed portion of the asphalt waterproofing layer 12 may be compressed, and at the same time, the silica sand may be sprayed to compress the exposed portion.

Meanwhile, in order to further reinforce the reinforcement between the reinforcing nonwoven fabric layer 13 and the asphalt waterproofing layer 12, a glass fiber mesh of about 100 mm may be further inserted.
