Functional foam composition for insole and preparing method of functional insole with free adhesive multi-layer using the same

摘要

More particularly, the present invention relates to an ethylene-vinyl acetate copolymer resin or an ethylene-α-olefin copolymer (ethylene-α-olefin copolymer) 5 to 15% by weight of an ethylene-vinyl acetate copolymer or an ethylene-? -olefin copolymer interlayer resin, 40 to 70% by weight of a foam polymer, 1 to 10% by weight of a rubber 2 to 3% by weight of a foaming rate controlling agent, 1 to 2% by weight of an additive, 1 to 2% by weight of a tackifier, 3 to 7% by weight of a foaming agent, 0.5 to 1.5% by weight of a crosslinking agent; And 0.1 to 0.5% by weight of a crosslinking auxiliary. The foam composition for a functional insole according to the present invention and the method for manufacturing an adhesiveless multi-layered functional insole using the same can improve the harmful work, remove harmful substances inside the insole, improve the physical properties, shorten the manufacturing process, And so on.
