Abstract
A method of manufacturing an adhesive foamed product for use in a hollow component of a motorcar, includes the steps of mixing an adhesive resin, a foaming agent, a crosslinking agent, a foaming accelerator and a polymerizable monomer to thereby formulate a highly foamable composition, arranging the foamable composition thus formulated in the interior of a hollow component of a motorcar, and heating the foamable composition until it is foamed to have a shape corresponding substantially to the shape of the hollow component.
Claims4
A method of manufacturing a motorcar component having a foam-filled interior comprising the steps of:
- mixing together:
- an adhesive resin selected from the group consisting of ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer, ethylene-butyl acrylate copolymer and a polymer blend of ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer or ethylene-butyl acrylate copolymer with low density polyethylene;
- a foaming agent;
- a crosslinking agent;
- a foaming accelerator;
- and
- a polymerizable monomer selected from the group consisting of triallyl cyanurate, triallyl isocyanurate, trimethylolpropane trimethacrylate and mixtures thereof;
- to thereby formulate a highly foamable composition;
- arranging the foamable composition thus formulated in the interior of a hollow motorcar component;
- and
- heating the foamable composition arranged in the interior of the hollow component until it is foamed to have a shape corresponding substantially to the shape of the interior of the hollow component.
