SEALING TAPE FOR ADHESIVE JOINT OF VAPOR-BARRIER FILMS AND METHOD OF ITS PRODUCTION

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to process engineering. Proposed tape is made from flexible self-adhesive bearing inner layer that features thermoplastic properties and is furnished with two-side coat. The latter is made from foamed adhesive tape with foam-like structure built on water dispersion of adhesive material (pure dispersion acrylate, adhesive material based on isobutyl vinyl ether or isobutene) with a filler representing minor thermoplastic gaseous-hydrocarbon-filled hollow spheres made from plastic that expand at temperature varying from 70C to 140C. ^ EFFECT: higher reliability of sealing, elasticity preserving, deformations compensation fast adhesion, and no harm to environments. ^ 11 cl
