BONDING METHOD OF RESIN AND PLASTIC PRODUCT CONTAINING DIFFERENT RESIN HAVING IMPROVED BONDING STRENGTH

摘要

PROBLEM TO BE SOLVED: To provide a resin bonding method, by which the bonding strength between a hollow molded article obtained by utilizing a rotational molding and a foamed urethane resin poured in the hollow cavity of the hollow molded article can be enhanced, and a plastic product, which is manufactured by the above-mentioned method and in which the bonding strength between the rotational thermoplastic resin molded article and the foamed urethane resin within the rotational thermoplastic resin molded article is enhanced. SOLUTION: A hollow molded article 2 is produced by means of a rotational molding from a shock thermoplastic resin mixed with 0.029-8.9wt.% of an inorganic filler so as to pour a foaming urethane resin 3 in the hollow cavity of the mold article.
