The fatty acid methyl ester may be included in an amount of 1 to 35 parts by weight based on 100 parts by weight of an epoxy resin, and 1 to 50 parts by weight based on 100 parts by weight of a curing agent resin. When the content of the fatty acid methyl ester is in the above range, the plasticity, moisturizing, dilution, lubrication, etc. of the adhesive are most excellent, and can effectively replace phthalate-based plasticizers, which are environmental regulations. On the other hand, when the fatty acid methyl ester is added in an excessive amount, problems such as initial adhesion and lowering of adhesion may occur.

Emulsifier

The emulsifier included in the main agent and the curing agent in the building interior construction adhesive according to the present invention serves to improve the water dispersibility and storage stability of the composition, and if the emulsifier can be used within a range that does not generally lower the physical properties of the adhesive It is preferable to use a composition of an emulsifier composed of a poly glycerine fatty acid ester and a poly oxyethylene blend regardless of the use.

The emulsifier may be included in an amount of 5 to 15 parts by weight based on 100 parts by weight of an epoxy resin, and may be included in an amount of 5 to 15 parts by weight based on 100 parts by weight of a curing agent resin. The water dispersibility and storage stability of the adhesive within the above range is the best, and when excessively added to the main or hardener may lower the adhesion.
