MANUFACTURING METHOD OF A FUNCTIONAL FOAM COMPOSITION, CAPABLE OF IMPROVING FOAM PERFORMANCE OF A POLYETHYLENE TEREPHTHALATE POLYMER BY BLENDING A MODIFIER INTO THE POLYETHYLENE TEREPHTHALATE POLYMER

摘要

PURPOSE: A manufacturing method of a functional foam composition is provided to improve foam properties of a polyethylene terephthalate copolymer which is an environmentally friendly material by using a modifier.;CONSTITUTION: A manufacturing method of a functional foam composition comprises: a step of preparing pellets which comprises 50-60 parts by weight of polyethylene terephthalate polymer, 15-25 parts by weight of a modifier, 5-10 parts by weight of a surfactant, 3-7 parts by weight of an antimicrobial agent, 2-5 parts by weight of a softening agent, 2-5 parts by weight of a stabilizer, 0.5-2 a parts by weight of a lubricant, and 0.5-2 parts by weight of an antioxidant; and a step of preparing a foam body by adding 2-5 parts by weight of foaming nitrogen into 100.0 parts by weight of the pellets. The modifier is selected from polycaprolactone, polyglucuronic acid, polylactic acid, polybutylene terephthalate, polybutylene adipate, and a copolymer thereof.;COPYRIGHT KIPO 2013
