Epoxy resin has elongated hydroxyl group and epoxy group, and the
elongated hydroxyl group can react with isocyanate. Epoxy resin as a
polyol directly added to polyurethane adhesive containing hydroxyl
components, using this method, only the hydroxyl group to participate in
the reaction, the epoxy group failed to react.
With acidic resin, carboxylic acid, so that the epoxy ring-opening, and then
react with the isocyanate in the polyurethane adhesive. Can also dissolve
the epoxy resin in ethyl acetate, add phosphoric acid heating reaction, its
adducts added to the polyurethane adhesive; the initial viscosity of the glue;
heat resistance and hydrolytic stability can be improved 0 r can also be used
Alcohol amine or amine reaction to generate polyols, the presence of tertiary
nitrogen atoms in the adducts, which can accelerate the NCO reaction. The
use of epoxy resin as a polyhydroxy component combines the advantages of polyurethane
and epoxy resin, with better adhesive strength and chemical resistance properties
