Epoxy resin adhesive composition and perforated floor panel for clean room comprising the same

摘要

The present invention provides an epoxy resin adhesive composition and a perforated floor panel for a clean room including the same. The epoxy resin adhesive composition, which is a two-component epoxy resin adhesive composition, includes a main material and a curing agent, wherein the main material includes 18 - 25.7 wt% of a basic epoxy resin, 15 - 22.4 wt% of a modified epoxy resin, 7.3 - 13 wt% of a polyester resin for providing adhesivity, 7 — 19.5 wt% of a methyl ethyl ketone (MEK) solvent for adjusting viscosity, 0.15 — 30.2 wt% of epoxy silane for increasing adhesivity, 6 — 15 wt% of graphite for providing conductivity, 8 - 30 wt% of a first filler for providing viscosity, 5 — 45 wt% of a second filler for providing thixotropy, and 0.01 — 10 wt% of a dispersant for dispersing the first and second fillers, the curing agent includes 14 — 30 wt% of a middle-viscosity amide compound, 10 - 35 wt% of a low-viscosity amide compound, 1.1 — 8.5 wt% of a catalyst for promoting curing, 0.5 - 15 wt% of a methyl ethyl ketone (MEK) solvent for adjusting viscosity, 0.01 - 8 wt% of epoxy silane for increasing adhesivity, 10 - 60 wt% of a first filler for providing viscosity, and 3 — 17 wt% of a second filler for providing thixotropy, and the main material and the curing agent are mixed at a weight ratio of 2:1.
