本考案は主として建築物の屋上を断熱しかつ防
水施工するための下地板として用いる防水断熱材
に関するものである。[Detailed Description of the Invention] The present invention mainly relates to a waterproof heat insulating material used as a base plate for insulating and waterproofing the roof of a building.
一般にコンクリート建築物の屋上に対する防水

構造のものが用いられている。 Generally, in waterproofing the rooftop of a concrete building, as shown in Figure 1, heat-fused asphalt b is laid on a concrete frame a, a waterproof and insulating material c is placed on top of it, and a heat-fused asphalt b is placed on top of this. A construction method has been adopted in which asphalt d is laid down and a waterproof layer e is further applied.Conventionally, as waterproof insulation material c, a face material is placed on both sides of a core material f made of synthetic resin foam as shown in Figure 2. A structure in which nonwoven fabrics i and i' coated or impregnated with asphalt h and h' are coated as g and g', and a polyethylene film j is placed on the nonwoven fabric i on the side of the concrete frame a, or as shown in Fig. 3. As shown, a core material f made of synthetic resin foam is coated with asphalt-impregnated felts k and k' as face materials g and g' on both sides.

がとられ、施工に支障をきたす欠点があつた。 However, in the case of the heat insulating material c having the structure shown in Fig. 2, adhesion occurs during packaging, so it is customary to use a polyethylene film J or the like as a release film, which is then peeled off during construction. However, the process required for this peeling cannot be ignored;
This was hindering work efficiency. In addition, this polyethylene film j may be peeled off before being stored and packaged, but in such cases, the uncoated asphalt surface h′ of the polyethylene film In some cases, products adhered to each other during packaging, causing a great deal of trouble. In addition, when constructing this heat insulating material c on a concrete body a, asphalt b molten at a high temperature is poured onto the concrete body a, and then the heat insulating material c is applied to the concrete body a.
When the polyethylene film j is bonded as is without peeling, when the temperature of the hot melt asphalt b is low or partially low, the polyethylene film j cannot be completely melted, and the polyethylene film j is stuck between the hot melt asphalt b and the nonwoven fabric i. This has the disadvantage that it leaves residue and causes poor adhesion, which poses a major problem in construction in winter or in cold regions. Furthermore, after laying the insulation material c on the concrete frame a,
When constructing the waterproof layer e, the installer uses this insulation material c.
However, in this case as well, the adhesive strength of the asphalt h' surface of the insulation material c hinders the installer's steps, which hinders the construction process.

覆し難い問題もあつた。 Furthermore, when a polyethylene film j is coated on one of the nonwoven fabrics i coated or impregnated with asphalt h, air may form on a part of the applied surface of the polyethylene film j due to the presence of moisture, air, etc. in the asphalt h or the nonwoven fabric i. There were also problems in that it was easy to form wrinkles due to accumulations, and it was difficult to cover the entire surface of the polyethylene film tightly.

点があつた。 In addition, insulating material c with the structure shown in Fig. 3 is thick and heavy, which is disadvantageous in manufacturing and construction, resulting in high costs, and the products adhere to each other like insulating material c in Fig. 2. There are drawbacks and felt k,
Due to moisture, heat, etc. contained in k', dimensional stability is poor, and there is a problem that warping and deformation easily occurs during storage and after installation.Also, the felt itself has poor water resistance, so water may not penetrate. However, it had the disadvantage of poor insulation properties.

To provide a waterproof heat insulating material that does not cause adhesion between products during packaging, has excellent adhesion during and after construction, and can achieve waterproof heat insulation on a rooftop with good workability.

着せず極めて能率よく作業できる。 This waterproof insulating material 7 is constructed in the same manner as the construction method shown in FIG. 1 described above (the waterproof insulating material 7 according to the present invention corresponds to the waterproof insulating material c in FIG. 1). In this case, synthetic resin films 5 and 5' each having a large number of small holes 4 and 4' are disposed on both surfaces of this waterproof and heat insulating material 7, so during waterproofing construction, these synthetic resin films 5 and 5 ′
Heat-melted asphalt b is coated on the concrete frame a and bonded to the waterproof insulation material 7 without peeling, or hot-melt asphalt d is coated on the waterproof heat insulation material 7 to bond the waterproof layer e.
Because of this, even if the synthetic resin films 5, 5' are not completely melted, the small pores melt and expand, and the asphalt b, d closes the small pores 4, 4' of the synthetic resin films 5, 5'. Through the non-woven fabric 3,
Asphalt 2 coated or impregnated with 3',
It penetrates into the asphalt 2' portion and is reliably integrated with the asphalt 2, 2'. Therefore, the adhesion is very good, and the synthetic resin films 5, 5' and the hot melt asphalt b,
Peeling is less likely to occur between d and d. Further, even after the waterproof insulation material 7 is installed, even when the installer walks on it, the asphalt 2' is not exposed on the surface, and the synthetic resin film 5' has many small holes 4' formed on the surface. Since it is coated, it does not stick to the feet of the installer and allows for extremely efficient work.

なく良好に施工することができたものである。 Furthermore, when the waterproof heat insulating material 7 is used for construction, there is no deterioration in heat insulation performance due to warping or water absorption, unlike when using asphalt-impregnated felt or the like. To explain this point in more detail, in experiments conducted by the present inventors, small holes 4,
If non-woven felt, paper, etc. are laminated instead of the synthetic resin films 5, 5' on which 4' is formed, and the asphalt 2, 2' generates decomposition gas due to the heat of the asphalt, if it is applied with hot asphalt without being removed. However, since this remained, blistering occurred and the construction could not be performed satisfactorily, but by covering and laminating the synthetic resin films 5, 5' in which small holes 4, 4' were formed, blistering occurred due to decomposition gas. The construction was successful without any problems.

優れている。 Furthermore, since the synthetic resin films 5, 5' in which many small holes 4, 4' are formed are coated, moisture is absorbed into the nonwoven fabrics 3, 3' or the asphalt 2, 2' coated or impregnated therewith. , air, etc. are present, these moisture, air, etc. escape from the small holes 4, 4' during or after coating and laminating the synthetic resin films 5, 5', and therefore, the synthetic resin films 5, 5' There are no wrinkles, etc.
It can be applied and covered uniformly and tightly, making it easy to manufacture the waterproof heat insulating material 7. Moreover, when the waterproof heat insulating material 7 is stored or packaged, the products do not adhere to each other, which is excellent in terms of workability.

It can improve workability due to adhesion when walking on waterproof insulation materials after construction, and it also adheres well to concrete, etc. without peeling off the synthetic resin film, and also prevents blistering, deformation, etc. It has properties that are very suitable for waterproofing and insulation construction on concrete rooftops, etc., such as being able to be applied to concrete roofs and improving work efficiency.
