Abstract

An environment-friendly adhesive composition is provided that includes about 10 to about 70 parts by weight of a tackifying agent base including an acryl-based attaching agent as a raw material, about 5 to about 40 parts by weight of a terpene-based tackiness improver, about 0.5 to about 5 parts by weight of an epoxy-based crosslinking agent, about 5 to about 60 parts by weight of a flame retardant, and a combination thereof, based on 100 parts by weight of a solvent excluding benzene, toluene and xylene (BTX). The flame retardant includes at least one selected from a group consisting of a halogen-based flame retardant, an antimony flame retardant, and a phosphorus-based flame retardant. The adhesive composition and a tape manufactured using the same may be used exclusively in a vehicle industry, and in various electronic industries.

First claim

What is claimed is:

1. An environment-friendly adhesive composition comprising:
about 10 to about 70 parts by weight of a tackifying agent base including an acryl-based attaching agent as a raw material;
about 5 to about 40 parts by weight of a terpene-based tackiness improver;
about 0.5 to about 5 parts by weight of an epoxy-based crosslinking agent; and
about 5 to about 60 parts by weight of a flame retardant including at least one selected from the group consisting of a halogen-based flame retardant, an antimony flame retardant, a phosphorus-based flame retardant, and a combination thereof,
based on 100 parts by weight of a solvent excluding benzene, toluene and xylene (BTX),
wherein the acryl-based attaching agent comprises butyl acylate (BAM), 2-hexyl ethyl acrylate (2-HEA), or a mixture thereof as a main monomer,
wherein the solvent includes about 5 to about 40 wt % of a C 2 to C 10 fatty acid ketone compound; about 20 to about 80 wt % of a C 1 to C 10 acetate compound; about 1 to about 10 wt % of a C 1 to C 10 alcohol compound; and about 1 to about 50 wt % of normal/cyclohexane compound, based on the total weight of the solvent,
wherein a glass transition temperature of the adhesive composition is about −50 to about −30° C.

2. The environment-friendly adhesive composition of claim 1 , wherein the halogen-based flame retardant in the flame retardant and the antimony flame retardant in the flame retardant are mixed at a weight ratio of about 90 to 100:about 45 to 50.

3. An adhesive tape manufactured using the adhesive composition according to claim 1 .

4. The adhesive tape of claim 3 , wherein a base material for manufacturing the tape is selected from the group consisting of polyethylene terephthalate (PET), polyethylene (PE), and polyimide (PI).
