Description of the Related Art Conventionally, a coating film waterproof material applied to a heat insulating and waterproofing method using a hard urethane type heat insulating material is usually made by an asphalt thermal method, and the adhesiveness to the heat insulating material is good, and the asphalt waterproofing method itself Since it is constructed by stacking layers, the waterproof performance is reliable and has a sufficient track record, but these are all on the flat surface and cannot be used on the vertical surface. If this is applied as it is to a vertical surface, the hot asphalt applied by a brush or the like during the construction will sag and flow, making it impossible to secure a sufficient film thickness and lacking reliability in waterproof performance.

し、ひいては断熱効果の喪失に至る。Up to now, there is no proven waterproof film applied to hard urethane on a vertical surface, and a partially used waterproof film mainly composed of modified ethylene vinyl acetate resin emulsion is used. Has been done. These coating waterproof materials have good adhesion to the heat insulating layer only for a short period of time after being applied to the hard urethane heat insulating layer. However, after forming the coating film, although sufficient waterproof performance is exhibited in combination with the elastic performance of the coating film itself, the elasticity of the coating waterproof layer is lost and curing weakening progresses in a long-term environment. Therefore, the behavior of the heat insulation layer cannot be followed, and the behavior of the heat insulation layer follows the cracks generated between the heat insulation layer and the cracks etc. generated in the waterproof layer, which significantly impairs the appearance and rainwater or underground outer wall through the cracks. In the case of, groundwater flows into the heat insulation layer, and eventually the heat insulation effect is lost.

長期に亘って健全な断熱防水層が維持される。As described above, according to the waterproof membrane of the present invention, water vapor smoothly progresses from the surface of the waterproof membrane after being applied to the hard urethane type heat insulating layer, and the main component in the waterproof membrane is As the formation of a sound-proof waterproof layer having excellent elongation performance by the component (A) (meth) acrylic rubber proceeds, the curing reaction of the (B) epoxy resin emulsion and the (C) epoxy curing agent compounded and added is parallel to each other. As compared with the conventional acrylic rubber-based waterproofing material alone, the film formation of the coating film progresses more rapidly, and the reinforcing effect on the coating film obtained as a result of this epoxy curing reaction makes it better than the hard urethane type heat insulating layer. Adhesiveness develops. As a result, the coating waterproof material of the present invention sufficiently follows the behavior of the hard urethane heat insulating material as the base,
A sound insulating and waterproof layer is maintained for a long period of time.

節減等が期待出来る。Further, in the conventional construction of waterproof membranes and the like, an undercoat material called a primer or a sealer is previously applied to the construction substrate for the purpose of improving the adhesion between the construction substrate and the waterproof membrane. According to the waterproof membrane of the present invention, it is possible to directly apply the waterproof membrane to the hard urethane type heat insulating layer without the need to apply the undercoat material, and thus one step can be omitted as compared with the normal construction. Therefore, the construction period can be shortened and the construction cost can be reduced.

が良好となる。In addition, since the drying effect of the waterproof film of the coating film progresses rapidly, the time required to move to the next step in the conventional water-based coating film waterproof material is at least 2 when the top coating material is applied.
Although it took about 4 hours, the waterproof film of the present invention allows the next step to be performed by leaving an interval of about 6 hours after the construction, so that the work can be performed efficiently even in a construction site with a small area. It is possible to proceed. Further, the waterproof coating material of the present invention is excellent in the initial film-forming property after the construction, and therefore when rain is expected before the construction, the waterproof coating material of the present invention can be used even in an environment where the conventional construction is stopped. When it is possible to obtain a drying time without getting wet with rainwater for about 2 to 3 hours after construction, it is possible to perform construction, so at the actual construction site it is difficult to receive the external environment during construction, Good usability.
