Alkali-acid resistant building glue

Abstract

Alkali-acid resistant building glue is disclosed, belonging to the technical field of polymers. The glue is prepared by weighing 100-150 parts by weight of epoxy resin, 40-60 parts by weight of acetone-furfural resin, 4-5 parts by weight of acetone, 20-30 parts by weight of modified alumina, 10-15 parts by weight of composite flake alumina, 8-12 parts by weight of isocyanate and 5-8 parts by weight of calcium bicarbonate in order; mixing the epoxy resin and the acetone-furfural resin in a stirrer; adding the acetone, the modified alumina, the composite flake alumina, the isocyanate and the calcium bicarbonate into the stirrer in order; and stirring and mixing the materials at 50-60 DEG C at a rotation speed of 200-300 r/min for 35-70 min. The obtained glue has excellent alkali and acid resistance.
