Water-soluble core material composition, water-soluble core material, and method for producing the same
By using base sand, water-soluble resin and adhesive to prepare water-soluble core material, the problems of high energy consumption and insufficient strength of core mold material are solved. Room temperature hydrolysis and efficient base sand recovery are achieved, which improves the bending strength and recycling efficiency of the core material.

Abstract
A water-soluble core material composition, a water-soluble core material and a manufacturing method thereof. The water-soluble core material composition comprises: a base sand; a water-soluble resin; and a binder; wherein the base sand is 80 to 90 parts by weight, the water-soluble resin is 5 to 10 parts by weight, and the binder is 5 to 10 parts by weight; and the water-soluble resin comprises a polar nonionic group. The water-soluble core material composition can be decomposed into the base sand in normal temperature water.
