Abstract

PURPOSE: A urea resin molding compound with an improved coefficient of post- shrinkage and water absorption while accomplishing energy saving to a large extent, which is obtd. by compounding a solid urea precondensate, a base material and urea in a specified proportion.
CONSTITUTION: 70W80pts.wt. solid urea precondensate hereinafter described, 20W 30pts.wt. base material and 1W10pts.wt. urea are compounded. Said solid urea precondensate is obtd. by reacting urea with formaldehyde in the presence of an alkali catalyst in a reaction system contg. 13W25wt% water, and cooling and solidifying the produced resin syrup. A powder such as wood flour or crushed pulp is pref. as the base material. If necessry it is possible to compound an additive such as a curing agent, releaser or colorant.
