PURPOSE:To perform an bonding with an excellent hydraulic resistant and tensile strength, by a method wherein an bonding composition, consisting of an organic peroxide and a copolymer of ethylene and specified alpha-olefin, is caused to lie between surfaces of a crosslinking polyolefin molded product. CONSTITUTION:Between surfaces to be bonded of a crosslinking polyolefin molded product, an bonding composition, consisting of an organic peroxide (preferably dialkylperoxides) and a copolymer (a ratio of alpha-olefin is 0.5-50wt% in a copolymer) of ethylene and alpha-olefin of C3-10 such as propylene, butane-1, is located, they are heated as they are pressurized by a molded product, and this bonds said molded product. Additionally, the amount of the peroxide used is preferably 0.1-20pts. for 100pts.wt. polyolefin. It is advisable that conjugated diene or ethylen unsaturated carboxylic acid (anhydrate), which is up to 10% of the copolymer, is used as a third component of said copolymer. EFFECT:To enable to perform an bonding without the use of a mechanical joint. |
