Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Figure 1 is an exemplary view showing the configuration of the composite waterproof structure according to the present invention, the present invention as shown in the drawings is a primer for adhesion augmentation applied to the concrete slab 60 of the structure and the primer 10 Is applied to the upper portion of the low melting point modified asphalt coating waterproofing material 20 to prevent water from penetrating into the structure, and the low melting point modified asphalt coating waterproofing material 20 is continuously attached so that one side overlaps the upper, low melting point Both sides of the double-sided silica sheet 30 is finished with silica sand so that the adhesion to the modified asphalt coating waterproofing material 20 can be improved, and between the two overlapping surfaces of the double-sided silica sheet 30 and the low melting point modified asphalt coating waterproofing material ( The joint member 40 is continuously applied to include a part of the surface 20 so that the overlapping portions of the double-sided silica sheet 30 are attached, and the upper portion of the overlapped portion of the double-sided silica sheet 30 is opened. It is applied which is closed by the overlapping area of the two-sided sheets of silica sand (30) and comprises a cover material 50 such that enhanced water efficiency.

The low melting point modified asphalt coating waterproofing material 20 has a low melting point on the upper portion of the primer 10, excellent workability or workability in the field is suppressed generation of harmful gases and can prevent the degradation of the coating waterproofing material due to high temperature melting 30-40 parts by weight of straight asphalt, 5-10 parts by weight of thermoplastic rubber, 5-10 parts by weight of petroleum resin, 20-30 parts by weight of gum rosin, and 30-40 parts by weight of process oil, 1-5 parts by weight of natural fiber It is composed as a main component and contains antifoaming agent, plasticizer, antioxidant, and anti-aging agent as subsidiary ingredients.

The low-melting-modified asphalt coating waterproofing material in the present invention controlled the content of the thermoplastic resin, synthetic resins such as coumarone indene resin, PP, PS and the like to increase the viscosity and hardness of the coating waterproofing material to increase the melting point, so their addition is In order to suppress and improve the dispersibility and fluidity, the process oil content was increased, and natural fiber was added to enhance strength and suppress oil content to improve adhesion.

The straight asphalt serves as a main component of the waterproofing material, and examples thereof include AP-3 or AP-5. The content of the straight asphalt is 30-40 parts by weight, but if the content is less than 30 parts by weight, the melting point is increased, there is a problem that the fluidity is reduced and plasticity is lowered, and if it exceeds 40 parts by weight, the adhesive strength is reduced, It is not preferable because of the increase in hardness.

In addition, the thermoplastic rubber may be exemplified by styrene-butadiene-styrene polymer (SBS) as a component used for modifying straight asphalt. When the content of the thermoplastic rubber is less than 5 parts by weight, the modification of the straight asphalt is not sufficient, on the contrary, when the content is more than 10 parts by weight, the melting point of the coating waterproofing material composition becomes too high to achieve the object of the present invention, which is the implementation of low melting point. Can't.

The petroleum resin is to vulcanize the improved asphalt, and to enhance the tensile performance (tensile strength or elongation) and hardness at room temperature. When a small amount is mixed, the petroleum resin has a slight effect on physical properties. There is a risk of impairing the odor and the properties of the existing improved asphalt, so 5 to 10 parts by weight is added in an appropriate range. Types of petroleum resins include C-9, C-5, coumarone, and the like.

Gum rosin is used to enhance the fluidity at the desired working temperature, maintain the hardness at room temperature, and improve the adhesion to improve the contact drying time at room temperature. While it is not possible to remove the bleeding phenomenon of the process oil, it is preferable to add 20 to 30 parts by weight since it is not preferable because it promotes hardening of the improved asphalt.

Process oil is used as a composition enhancer for the flowability, dispersibility and improved asphalt properties of the composition, and it is difficult to control the working temperature appropriately when mixing small amounts of asphalt and gumgin, and it is difficult to properly control the working temperature. It is difficult to secure an improvement in tensile performance or heat resistance, and when the amount is too large, plasticity is lost and form stability cannot be maintained. Therefore, an appropriate amount of process oil is 30 to 40 parts by weight. Types of process oils that can be used in the present invention include naphtans, paraffins, aromatics, and the like, and naphtan-based process oils are particularly preferable in consideration of compatibility with thermoplastic resins.

Natural fiber is used as a strength reinforcement and oil removal agent, and a small amount of premise is used, and when the amount is exceeded, it is preferable to use 1-5 parts by weight since it hardens rapidly by preventing the binding between additives.

Antifoaming agent is used for the defoaming at high temperature, and when used in a large amount, it is preferable to be within 0.1 part by weight since it causes gel development of improved asphalt. As an antifoamer, a silicone type antifoamer is preferable.

In addition, in the present invention, a plasticizer, an antioxidant, an anti-aging agent, and the like are included as subcomponents, and the plasticizer is used for the purpose of improving the balance of various physical properties. Examples of the plasticizer used in the present invention include (Phthalate-based DOP), and as the antioxidant (2,2,4-trimetyl-1,2-dihydroquinoleine) can be used, and as an antioxidant ( 6-Ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline). And each content of these subcomponents is suitable for the range (less than 0.1 part by weight).
