本発明は溝付き防水シートの製法に関するものである〇

を形成させるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a grooved waterproof sheet. Generally, when laying a waterproof sheet made of a polymer sheet on a base surface, an adhesive is applied to the sheet and the base surface, respectively. After drying, the adhesive surfaces are overlapped and pressed together to form a waterproof layer.
またかかる防水施工を簡単に行うために、前記高分子シ
ートの表面に、予め感圧接着層を形成したものも知られ
ている。Furthermore, in order to easily carry out such waterproof construction, it is known that a pressure-sensitive adhesive layer is previously formed on the surface of the polymer sheet.
これらのシート状防水材料を用いて防水施工を行うに際
して重要なことは、防水シートと下地面との間に空気を
抱き込まないようにすることであるが、シートが１ｍ前
後の広幅であることも相俟って、空気の抱き込みを防止
できないのが現状である。When carrying out waterproofing using these sheet-like waterproof materials, it is important to prevent air from being trapped between the waterproof sheet and the underlying surface, but the sheet must be approximately 1 meter wide. Due to these factors, the current situation is that air entrapment cannot be prevented.

ものであった。Such air entrapment reduces the adhesion area between the waterproof sheet and the underlying surface, which not only causes poor adhesion, but also causes the disadvantage of inducing blistering and peeling after installation. Tarpaulin sheets have been proposed that have ventilation channels or grooves to diffuse air trapped between the tarpaulin sheet and the underlying surface. However, ventilation channels are generally formed by pasting a coarse cloth such as a net-like non-woven fabric or cheesecloth, but the primer coated on the underlying surface impregnates and impairs breathability, so it is difficult to diffuse sufficiently. Furthermore, if the waterproof sheet has grooves, the grooves may be crushed and partially lost during storage from the time of manufacture to the time of use, making it impossible to obtain a sufficient diffusion effect. Ta.
殊に溝の喪失は、溝が感圧接着層面に付けられている場
合、その流動性に起因して多いものであった。The loss of grooves was particularly common when the grooves were applied to the surface of the pressure-sensitive adhesive layer due to its fluidity.

。The present invention provides a new method for manufacturing a waterproof sheet with grooves, which prevents the grooves from being lost during storage when the grooves are formed in the pressure-sensitive adhesive layer,
The gist of this is that a self-supporting peelable thermoplastic film is attached to the adhesive layer surface of a waterproof sheet made of a pressure-sensitive adhesive layer on the surface of a polymer sheet, and then heated. According to the manufacturing method of the present invention, the film is bonded to the surface of the adhesive layer while heating, and then an engraved roll is pressed against the surface of the film to form grooves of a desired shape in the adhesive layer and the film. For example, the desired shape of the groove formed in the pressure-sensitive adhesive layer is held by a self-supporting thermoplastic film shaped into the same shape, so it can be wound into a roll or a sheet and layered. The grooves formed in the pressure-sensitive adhesive layer will not be lost even if the adhesive is stored.

A thick pressure sensitive adhesive layer of m or more, for example, an unvulcanized butyl rubber layer,
``The adhesive layer of the waterproof sheet provided with an acrylic copolymer layer, etc. has self-supporting properties with a thickness of 0.1 mm or more,
In addition, a releasable thermoplastic film, such as a polyolefin film, a polyvinyl chloride film, etc., which has been subjected to a release treatment such as a silicone release agent or a fluorine release agent, is bonded to the surface. Next, the film surface is heated mainly from the film surface at a temperature equal to or lower than the softening temperature of the film, and the film surface is positioned on the engraved roll surface between the engraved roll and the support roll on which the desired protruding pattern has been formed. The pattern of the engraved roll is imprinted on the adhesive layer and the film to form a groove.The thermoplastic film subjected to the peeling process is heated and softened before being bonded to the surface of the adhesive layer. Grooves may be formed in the adhesive layer and the film by bonding the film to the surface of the adhesive layer and then pressing it against an engraved roll. At this time, it is preferable to heat the waterproof sheet at the same time.
