However, this method is not only complicated in construction and requires a lot of effort and cost, but also due to the physical properties of the waterproof layer, heat insulation board, and sound insulation board, i.e., the elasticity due to temperature changes and the difference in water absorption. Expansion, contraction, and warping of water can cause cracks, rupture, and displacement of the waterproof layer, often resulting in water leakage accidents.

との結合力向上に役立つ。 The volume ratio of the closed cell plastic foam particles to the rubber asphalt emulsion is 1:0.5~
Blend at a ratio of 2.0 and mix evenly. However, foam particles have a low specific gravity and float, so to prevent this, asbestos, rock wool, glass fiber, synthetic fibers, and other short organic fibers are added as fibrous fillers to the rubber-asphalt emulsion in an amount of 1 to 5%. By doing so, lifting of the foam particles can be prevented and a uniform mixture can be obtained. Moreover, this fibrous filler is useful for improving the toughness of the cured coating film and the bonding strength between the rubber asphalt and the foam particles.

作業性が良好なようにする。 The composition of the present invention can be obtained by mixing a gelling agent into the homogeneous mixture of the rubber asphalt emulsion, closed-cell plastic foam particles, and fibrous filler prepared as described above. The gelling agent used in the present invention gradually destroys the dispersion state of the emulsion in water within several minutes to several tens of minutes after mixing, and separates water.
It hardens rubber asphalt, and includes sodium fluoride, zinc ammonium complex, Portland cement, and plaster. This gelling agent is added and mixed immediately before construction, and the amount added is usually about 1 to 2% by weight based on the rubber asphalt emulsion. Depending on the temperature difference, the amount added is selected to obtain the desired curing speed and to improve workability.

It was cured in 5 minutes after adding the sodium fluoride solution. The filled layer of this cured material is flexible and has a low elongation rate until cutting.
It is highly elastic at 150%, and extremely light with a specific gravity of 0.32.
Since the expanded granules contain more air bubbles than in Example 1, the insulation and sound insulation properties are even better, and the water permeability coefficient is 1 x 10 -8 cm/sec, resulting in a good insulation and waterproof filling layer. It was done.
