Description: TECHNICAL FIELD The present invention relates to an asphalt single for construction on a pitched roof of a building, and more particularly to an asphalt single with an adhesive having excellent wind resistance. (Technology) Conventionally, asphalt singles that are constructed on sloped roofs of houses, offices, etc., are asphalt singles that are first attached to the base plate such as plywood of the roof with a tucker and a roof base plate such as asphalt roofing. Is nailed in place and nailed up. At this time, when the adhesive is partially applied in a small area in a linear or dot shape in the longitudinal direction on the surface of the asphalt single,
With this adhesive, the upper layer asphalt single that is overlaid is adhered. If the surface of the asphalt single is not coated with adhesive, apply the adhesive to the back side of the tab when installing the asphalt single, and after the construction, the tab is lifted by strong wind and the asphalt single peels off. I try not to be.

(Problems to be solved by the invention) However, the adhesive that is partially applied in advance in a small area on the surface of the asphalt single has a softening point.
Since it is 55-65 ℃ straight asphalt, it will not bond unless it is loosened to 50 ℃ or more by solar heat after the asphalt single construction. Especially during construction in winter, there is almost no adhesion, so gusts in the early spring tend to cause the asphalt single to peel off. Even in the spring and autumn, the roof surface on the north side does not rise in temperature and does not bond.

Further, in the method of applying an adhesive to the back side of the tab portion for adhesion at the time of construction, this adhesive is easy to apply and, moreover, the adhesive is of a solvent type in order to exert its adhesive force at an early stage. Since it is such a solvent-type adhesive, when applied, the solvent shifts to asphalt single, and the solvent remaining in the adhesive gradually shifts to asphalt single to soften the asphalt. Due to this softening, air contained in the interface between the asphalt single and the asphalt and the sand is easily expanded by the solar heat, and the surface of the asphalt single is innumerably blistered, which has the drawback of significantly impairing the appearance.

Liquid polybutadiene rubber is a polymer that has fluidity at room temperature and is used to increase the adhesive strength of the adhesive used in the present invention at low temperatures. Some liquid polybutadiene rubbers have terminal functional groups such as carboxyl group and bromine group, and they can be used with good compatibility with asphalt, but hydroxyl group-terminated ones have the lowest viscosity. In terms of workability, it can be most preferably used.

The asphalt single of the present invention impregnates a base material with asphalt, like the conventional asphalt single.
Spread colored sand on the surface of the coated asphalt sheet,
After attaching silica sand to the back surface, apply a pre-adjusted adhesive to a predetermined position on the back surface with a roll coater at 0.3 to 0.8.
A linear film having a thickness of mm and a wide width is applied, and a release film or release paper, which is slightly wider than the adhesive-coated surface, is temporarily attached thereto. The asphalt single of the present application is obtained by being cut into a single shape through a cooling step, but is preliminarily set so that the adhesive is applied to an area of 30% or more of the back surface of the tab portion.

It is necessary to apply an adhesive to the back surface of the tab portion of the asphalt single of the present application over 30% or more of the area of the tab portion. The reason is that from the wind pressure formula given in Article 87 of the Enforcement Ordinance of the Building Standards Act, considering the maximum value of the results of typhoons measured near the coast of Japan, the instantaneous wind speed is 60m / In terms of seconds, a levitation force of about 18 kg works on the tab portion (about 380 cm 2 ) of the asphalt single. Since the adhesive strength of the adhesive applied to the back surface of the tab portion of the present invention at a high temperature (50 ° C.) is 0.15 Kg / cm 2 , in order to withstand the above wind pressure, the adhesive application area is The area must be 30% or more.

Straight asphalt with penetration of 0-10 is 180-190 ℃
After heating, liquid polybutadiene rubber (Poly bd R-45HT manufactured by Idemitsu Arco Co., Ltd.) and talc were added according to the compounding ratios of Table 1 (Examples 1 to 3 and Comparative Examples 1 to 3), and stirred for about 30 minutes. Mixed to obtain a uniform adhesive. The adhesive thus obtained was coated with silica sand on the back surface of the asphalt single manufacturing machine at the position corresponding to the tab portion of the asphalt single, and then applied in a line shape with a thickness of 0.5 mm and a width of 40 mm. A peelable polyethylene film having a thickness of 10 μm was temporarily attached to the surface, and a cooling process was performed to cut it into a single shape to produce an asphalt single with an adhesive.
