Composite null of the polyolefine formation item and the dissimilar material which possesses

摘要

PURPOSE:To obtain firm adhesion strength, by a method wherein a polyolefin molded product and a material of a different kind are stuck together through an adhesive layer comprised of combination of at least three ingredients. CONSTITUTION:A polyolefin molded product and a material of a different kind having a polarity are stuck together through an adhesive layer of a composition constituted of chlorinated polypropylene A whose content of chlorine is not exceeding 35wt.%, a mixture B of at least a kind or two kinds of either of SBS and SEBS and a mixture C of at least a kind or two kinds of either terpene resin and alicyclic hydrocarbon resin. Preferable combination of ingredients each is that the A, B and C are respectively the chlorinated polypropylene whose content of chlorine is 20-30wt.% the SEBS and hydrogenated terpene resin and preferable compounding ratios of the above-mentioned ingredients each such as A/(A+B+C) and B/(B+C) are respectively 1-90wt.% and 10-90wt.%. Hereupon, a method such as iron/aluminum, ceramics such as glass/ pottery and a natural material and synthetic resin which possess hydroxyl group/amino group or amino linkage and is durable for heating for adhesion.
