Embodiment 1～3

[0038] Adhesive compositions were formed according to the composition of the tackifier base in Table 1 below and the composition ratios in Table 2 below. Such as image 3 Shown to manufacture tapes with complex structures. A 75 μm thick layer of tackifier PSA was coated on a black PET film, a 75 μm thick nonwoven layer was laminated on it, a 75 μm thick layer of tackifier PSA was coated again, and the prepared adhesive was coated Covered on PET film. Once the adhesive was applied to the PET film, the odor was reduced by fully evaporating the odor elements and gradually increasing the temperature during the drying process from an initial moderate temperature to a temperature of about 110°C to maximize inhibition of tackifier coating. Tape samples were produced by reducing the odor by volatilizing the remaining odor elements during long-term aging at a temperature of about 43°C.

[0047] Experimental Example: Measurement of Physical Properties

[0048] The physical properties of the samples manufactured according to Examples 1 to 3 and Comparative Examples 1 to 3 were determined by the following methods. The results are described in Table 3 below. The physical property results described in Table 4 below provide an average of five tape samples measured except for the highest and lowest values. Its test method is described as follows:

[0049] (1) Determination of VOC amount: The discharged VOC amount is measured by the standard MS 300-55 test method. The unit of emitted VOC is μg / m 3 .

[0050] (2) Odor determination: The amount of odor was determined by the standard MS 300-34 test method. The conversion ratio is obtained by dividing the weight average molecular weight (Mw) by the number average molecular weight (Mn). Set up a reference vs. standard comparison with an odor rating of 4 or more scales. An increase in conversion ratio represents a ...

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.

Description

technical field [0001] The present invention relates to an environmentally friendly adhesive composition and an adhesive tape manufactured using the same, and in particular to an environmentally friendly adhesive composition that can be widely used in the automobile industry, the electronic industry, and the like. The present invention provides an environmentally friendly adhesive composition and an adhesive tape manufactured using the adhesive composition, which can be used without aromatic petrochemicals such as benzene, toluene and xylene (BTX) The solvent contains a tackifier base, a terpene-based tackifier (ie, tackifier), a crosslinker, and a small amount of flame retardant. Background technique [0002] In recent manufacturing industries, various adhesives and tape-type adhesive materials have been widely used. Meanwhile, many countries have strengthened environmental regulations of such industrial products used especially in electronic products, automobiles, and the...
