The present invention relates to a method for joining tubes. Currently, many polyvinyl chloride pipes are used in water and sewage systems, but when joining, adhesive is applied to the polyvinyl chloride pipes and the pipes are fixed with adhesive after joining. This has the disadvantage that when the pipe expands, stress is applied to the joint, and the solvent and compounding agents used in the adhesive may have a negative effect on the polyvinyl chloride or be undesirable from an environmental hygiene perspective. There is. On the other hand, the rubber sealing method is used to join pipes such as polyvinyl chloride pipes, steel pipes, and hume pipes (centrifugal reinforced concrete pipes). A method of coating and joining the pipes was started, but the lubricants used were metal salts of higher fatty acids such as potassium oleate, fatty acid esters such as methyl stearate, lower hydrocarbons, methylcellulose, methyl benzoate, etc. Since it is water-soluble, it is difficult to apply in the rain or underwater, and it has disadvantages such as dissolving in fluids in pipes after application. The present invention was completed as a result of intensive studies to solve the above problems. The lubricant used in the present invention is mainly composed of one or more compounds selected from the group consisting of castor oil, castor oil monoglyceride, and ricinoleic acid monoglyceride, and a thickener and polyhydric alcohol are added thereto. Thickeners include silicic acid or aluminum-based minerals such as anhydrous silicic acid, anhydrous sodium silicate, anhydrous aluminum silicate, anhydrous magnesium silicate, aluminum octylate, and aluminum stearate. Examples of the alcohol include polyethylene glycol, propylene glycol, glyceroltrimethylolpropane, pentaerythritol, etc., and these thickeners and polyhydric alcohols can be used alone or in combination of two or more. In carrying out the present invention, there are no particular restrictions on the ratio of thickeners and polyhydric alcohols added to the main ingredients such as castor oil, but approximately 1 to 30 parts by weight of the latter should be added to 100 parts by weight of the former. do it. The pipe joining method of the present invention is a rubber ring method in which a lubricant is used, and after a rubber ring is wrapped around the joint of the male or female pipe, the inner or outer surface of the rubber ring or the male or female pipe is The above lubricant is applied to the outer or inner surface of the tube, and the male tube is inserted into the female tube and joined. The lubricant used in the present invention is non-toxic and
According to the present invention, there is an advantage that the PVC pipes can be easily joined without using the time-consuming method of applying an adhesive to join the PVC pipes. In addition, it has lubricity during and after joining, so no stress is applied to the joints of pipes, and it does not have a negative effect on pipes such as polyvinyl chloride pipes or rubber rings.Furthermore, since it is non-water soluble, it does not affect water quality or water-based properties. It is industrially useful because it does not adversely affect fluids and can be easily bonded in rainy weather or underwater. Next, the present invention will be explained with reference to Examples and Test Examples, but the present invention is not limited to these Examples and Test Examples. Example Each of the ingredients shown in Table 1 was mixed with sufficient heating and stirring to prepare each lubricant for pipe joining. Next, a rubber ring is fitted to the female pipe of a hard vinyl chloride pipe (JISK6741), and the lubricant is applied to the inner surface of the rubber ring and the outer peripheral surface of the end of the male pipe, and then the male pipe is press-fitted into the female pipe. Join the male and female tubes.
