Abstract
The present disclosure provides a preparation method of a flame-retardant degradable adhesive tape, including: preparing a degradable adhesive tape base layer and a flame-retardant degradable adhesive tape bonding layer separately, and then conducting coating, curing, and aging of the flame-retardant degradable adhesive tape bonding layer on a surface of the degradable adhesive tape base layer to obtain the flame-retardant degradable adhesive tape; where the degradable adhesive tape base layer is prepared by subjecting bis(2-hydroxybutyl) terephthalate (BHBT) and bis(2-hydroxybutyl) adipate (BHAT) to transesterification and polycondensation to obtain a degradable poly(butylene adipate-co-terephthalate) (PBAT) polymer polymer, and then conducting blow molding on the degradable PBAT polymer; the flame-retardant degradable adhesive tape bonding layer is prepared by subjecting the BHBT, the BHAT, and a pressure-sensitive adhesive (PSA) additive to transesterification and polycondensation to obtain a colloidal flame-retardant degradable PBAT polymer, and conducting curing on the colloidal flame-retardant degradable PBAT polymer.
