Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application The present invention relates to a waterproof and soundproof surface treatment method for use in architecture, shipbuilding, etc.

<Prior art> In the conventional waterproof and soundproof surface treatment method, as shown in Fig. 3,
Apply adhesive +11:4- to the surface of 10, press and adhere foamed synthetic resin heat insulating board 13 (trade name: Kanelite Foam, manufactured by Kanebo Co., Ltd.) to this adhesive, and apply cement to the surface of heat insulating board 13 as necessary. 114 was the only method required.

Problems to be Solved by the Invention 〉 However, in the past, the adhesive 12 was expensive and semi-dry rubber paste-like, so even if you tried to apply the adhesive to the entire surface with a comb trowel, the adhesive would not work properly. Since the heat insulating board 13 is pasted with areas where it does not stick, the air trapped in the areas where there is no adhesive expands and contracts repeatedly due to temperature changes, causing the heat insulating board 13 to crack or peel. Another disadvantage is that the adhesive melts the insulation board, and the construction time and cost are too high.

Therefore, the present invention uses an adhesive that is mainly composed of a water-based synthetic resin that can be easily applied to the entire surface, and also uses screws or other screws to prevent cracks and peeling of the insulation board. The purpose is to provide a waterproof and soundproof surface treatment method that can significantly reduce construction costs.

<Means for Solving the Problem> As shown in FIG. 1, the means for solving the problem according to the present invention is as follows: As shown in FIG. Next, a water-based adhesive layer 5 is formed on the back side of a foamed synthetic resin insulation board 6, and the insulation board 6 is inserted into the retaining rod 2, and at the same time, the water-based adhesive layer 5 is pressed onto the surface of the substrate 1. It is something to be glued.

In the above means for solving the problem, since the water-based adhesive has a water-based synthetic resin as its main component, it is extremely easy to apply it to the entire surface of the heat insulating board 6 (or the board 1), and the board 1 is secured to the board 1 by the retaining rod 2 such as a screw. The heat insulating board 6 is always maintained in a fixed state for many years, and it is possible to completely eliminate cracks and peeling of the insulating board due to air trapped in areas where there is no adhesive, which repeatedly stretches and contracts due to temperature changes. Construction time and costs can also be reduced.

<Example> The present invention will be described in detail below. First, the first embodiment will be described with reference to FIG. 1. First, a substrate 1 made of a hard metal plate such as an iron plate is coated with projections and recesses (screw recesses) 2a to prevent screws from coming out by welding or using an adhesive. A plurality of retaining rods 2 are stood upright at an appropriate pitch, and then a rust preventive layer 3 is formed on the surface of the substrate 1, and then a diluted adhesive layer 4 (for example, 1/12 m
form m).

Next, a water-based adhesive layer 5 (e.g. 1/4 mm)
is formed on the back side of a heat insulating board 6 made of foamed synthetic resin, and the heat insulating board 6 is inserted into the retaining rod 2 so that the tip of the retaining rod 2 is buried in the insulating board 6, and at the same time, the water-based adhesive immediately after application is applied. layer 5
is pressed onto the diluted adhesive layer 4.

Next, a base protective agent layer 7 (for example, 2 to 3
mm) is formed, and then a surface paint layer 8 (for example, 1/3 mm) is formed on the surface of the base protective agent layer 7.

Note that the substrate 1 is well polished, and the removal prevention rod 2 has an area of 900 mm.
Insulating board 6 with mmX1800mm and thickness 15-20mm
Weld to attach. After drying the rust-preventing layer 3, a diluted adhesive (water-based adhesive diluted three times) is sprayed, applied and dried using a roller plastering brush. Step 1: Apply enough water-based adhesive to the lower surface of the heat insulating board 6, and then stick the adhesive on the heat insulating board 6 so as to rub it against the diluted adhesive layer 4 on the substrate 1 side.

Here, the water-based adhesive is 1% by weight, 45% by weight of the water-based synthetic resin (for example, Toyo Ink Co., Ltd. under the trade name Togri),
Consisting of 25% water-based asphalt, 28% water, and 2% sodium 6-sametalifsan, the coating weight is 2% per square meter.
It is 66g.

Also, the weight percent of the base protective agent is 20? . , Sand material (300 mesh or less) 80? It is mixed and stirred on site, and the coating weight is 3 per square meter.
, 700 g, and after coating with a trowel and drying with a rubber brush, apply a surface paint consisting of water-based paint and dry.

Next, a second embodiment will be explained with reference to FIG. 2. This is suitable for construction on flat roofs, earthen floors, under floors, above floors, basement walls, etc., where the substrate 1 is made of concrete plates, etc.
A diluted adhesive layer 4 (when the substrate 1 is new, 3
A double diluted aqueous adhesive cutting layer 4) is formed by coating and drying.

Next, a water-based adhesive layer 5 is formed on the back surface of the heat insulating board 6, and the adhesive layer 5 immediately after application of the heat insulating board 6 is pressed against the diluted adhesive layer 4. Thereafter, a retaining rod 2 (concrete nail, wood screw, etc.) with a pointed screw-shaped pointed end retaining unevenness 2a is driven into the surface of the heat insulating board 6 to cause the pointed end retaining irregularity 2a of the retaining rod 2 to dig into the substrate 1. At the same time, the dish-shaped head 2b is attached to the heat insulating plate 6.
Next, a base protective agent layer 7 (for example, 3 to 6 mm thick) is formed on the surface of the heat insulating board 6, and then a surface paint layer 8 is formed on the surface of this base protective agent layer 7.

In addition, in the second embodiment shown in FIG. 2, the inner and outer walls, the rising edge,
When applying to Kasagi etc., the base protectant is used by mixing and stirring 35% of the adhesive of the water-based adhesive layer 5 and 65% of crushed slag (300 mesh or less) on site.

In addition, when applying to prevent moisture and flaking in rooftop parking lots, refrigerators, vegetable storage, and warehouses, use a 20% water-based adhesive as a base protector.
, 80% sand aggregate is mixed and stirred and formed into a thickness of 3 to 6 mm.

Furthermore, in the second embodiment, when the substrate 1 is a wooden board, plywood, or white cotton board, the base protective agent layer 7 is formed of a mixture of 80% sand aggregate and 10% water-based adhesive to a thickness of 2 to 3 mm. or a mixture of 65% ground slag (light and non-inhalable water-based) and 35% water-based adhesive.

Build a telephone box type room with the walls of the second embodiment,
We conducted a test to confirm its soundproofing effect. The results are as follows.
