Abstract

PURPOSE: To make the working life of mulled sand longer, enhance the strength of molds, and improve the productivity of drawing molds, sweeping molds and strickles by mulling silica sand with an acid curing type org. self-curing resin, an acid curing catalyst and an org. polymer.
CONSTITUTION: The acid curing type org. self-curing resin includes urea-aldehyde resins, melamine-aldehyde resins, phenol-aldehyde resins, etc. Next, the acid curing catalyst includes benzenesulfonic acids, p-toluenesulfonic acids, m-xylenesulfonic acids, etc. These are used as a 10W95wt% soln. of alcohol. The org. polymer imparting thickening property includes polyvinyl alcohols, cellulose derivatives butadiene copolymers, etc. and these are used in the form of powder, soln. or emulsified liquid. The amounts of the use of these components are 0.5W5wt% and 0.1W 5pts.wt. based on 100pts.wt. of sand in the case of the acid curing type org. self- curing resin and the acid curing catalyst, and a 0.3W5pts.wt. range in the case of the thickening property imparting org. polymer.
