塗布の有無判断を行っていた。[Prior art] Generally, when joining a hard vinyl chloride pipe and a fitting, adhesive is applied to the outer circumferential surface of the end of the hard vinyl chloride pipe and the inner circumferential surface of the socket of the fitting, and then hard chloride is applied to the successor socket. The joining is completed by keeping the end of the vinyl pipe inserted and drying it. At this time, the adhesive protrudes from the end face of the joint, and the presence or absence of adhesive application is determined by visually observing this ``protrusion''.

で、このような接着剤の塗り忘れがないかどうかを目視
によって確認しなければならない。By the way, when installing piping inside a building or the like, it is sometimes necessary to first temporarily join the parts without applying an adhesive to adjust the dimensions or the like, and then apply adhesive to the joint part and then connect the pipes. However, if the adhesive is forgotten to be applied, a water leakage accident may occur during a water flow test, resulting in great damage. Therefore, it is necessary to visually check whether or not the adhesive has been left unapplied.
しかしながら、従来の硬質塩化ビニル管用接着剤は無色
透明であり、他方管表面の色調は灰色。However, conventional hard PVC pipe adhesives are colorless and transparent, while the pipe surface is gray in color.
青色、黒色などであり、したがって、目視によって接着

になってしまう。Additionally, there is an adhesive for communication pipe materials that is colored blue to facilitate such visual judgment. Visual confirmation is possible when this adhesive for communication pipes is used on gray hard PVC pipes, but it is difficult to visually check blue or black impact-resistant hard PVC pipes because they have similar colors. Become.
それゆえに、この発明の主たる目的は、接着剤を塗布し

機溶剤を含む接着剤と一定粒径の白色顔料を一定の割合
で配合した、硬質塩化ビニル管用接着剤である。To put it simply, this invention is an adhesive for hard vinyl chloride pipes, which is a mixture of an adhesive containing a vinyl chloride resin and an organic solvent, and a white pigment of a certain particle size in a certain proportion.
従来のドープセメントタイプの硬質塩化ビニル管用接着
剤に配合された、たとえば炭酸カルシウムやチタン白の
白色顔料によって、この接着剤は白色を呈する。The white color of the adhesive is due to the white pigments, such as calcium carbonate and titanium white, added to the conventional dope cement type hard vinyl chloride pipe adhesive.
この発明によれば、色調が白色の硬質塩化ビニル管用接

、漏水事故などの弊害を防止できる。According to this invention, since a hard vinyl chloride pipe adhesive with a white color can be obtained, whether the pipe surface is gray, blue, or black can be visually checked to see if it has been applied. It is extremely easy to do. therefore,
There is no longer the need to forget to apply adhesive as in the past, and problems such as water leaks can be prevented.
この発明の上述の目的、その他の目的、特徴および利点

Acetone, tetrahydrofuran, methyl ethyl ketone and cyclohexanone are used as organic solvents. To 100 parts by weight of this adhesive, 5 parts by weight of titanium white having a particle size of 1 to 10 μm is blended. However, titanium white is resin 1
The number of copies was reduced to 25 or less compared to 00 copies.
このようにして形成される硬質塩化ビニル管用接着剤に
ついて、従来例と比較するため、以下のような接着強度
試験を行った。For the hard vinyl chloride pipe adhesive thus formed, the following adhesive strength test was conducted in order to compare it with a conventional example.

９３０°Ｃ）の恒温槽に入れて２時間以上養生する。■The test tube was cut into pieces of approximately 20cIIl each, and the test tube, test joint (socket), and hard PVC pipe adhesive of this example were heated at a preset temperature (O”C, 20°C).
Place in a constant temperature bath (930°C) and cure for 2 hours or more.
■そして、供試管（呼び径５０φ）に標線を記入してお

に塗布し、挿入後２０〜３０秒保持する。(2) Then, mark a marked line on the test tube (nominal diameter 50φ), apply the adhesive uniformly to the adhesive surface of the test tube and the inner surface of the joint, and hold for 20 to 30 seconds after insertion.
■規定の養生時間の養生後、水圧を加え、接着部が抜は
始める時の水圧を測定する。■After curing for the specified curing time, apply water pressure and measure the water pressure when the adhesive starts to come off.
この実験結果は、皮表のようであり、従来と殆ど同等の
接着強度を発揮することがわかった。The experimental results were similar to the surface of skin, and it was found that the adhesive strength was almost the same as that of conventional adhesives.
