Abstract: PURPOSE:To provide the green sand compsn. for production of castings by which a green sand mold having excellent surface stability is obtd. even with the small volume of water. CONSTITUTION:This green sand compsn. contains a surfactant and polyhydric alcohol as essential components. any of anionic surfactants, noionic surfactants, cationic surfactants and amphoteric surfactants is usable for this surfactant. Glycerine, ethylene glycol, diglycerine, etc., are representatively used as the polyhydric alcohol. Bentonite is generally used as the clay in the green sand compsn. for production of castings. Adhesives, such as carbides including coal powder, etc., and starch may be incorporated as arbitrary components into the green sand compsn. for production of castings. This green sand compsn. for production of castings is formed by adding clay, the surfactant and the polyhydric alcohol to sand. The surfactant and the polyhydric alcohol are preferably added simultaneously in the form of an aq. soln. to the sand.

Abstract: PURPOSE:To improve a collapsing property and to eliminate the need for a heat treatment in a knock-out stage as well as to decrease the number of stages by using the specific compsn. for the sand core to be applied to an undercut part. CONSTITUTION:This peroxide compsn. is used at the time of producing the sand core to be applied to the undercut part by blowing gaseous or aerosol sulfur dioxide into a sand mold molded by adding and kneading an acid curing resin and the peroxide compsn. to and with refractory granular aggregate in die casting for casting a light alloy under several 10 to several 100kg/cm pressure. The peroxide compsn. for the sand core for high-pressure casting is the hydrous ketone peroxide compsn. contg. a dilution stabilizer emulsion dispersed or solubilized by a solubilizing agent or surfactant.

Abstract: PURPOSE:To increase a curing speed and to obtain the casting mold having high initial strength by incorporating a specific ratio of a hardening accelerator consisting of one or >=2 kinds of the compds. expressed by formula into a binder compsn. CONSTITUTION:This binder compsn. for production of the casting mold consists of a thermosetting resin and the hardening accelerator as essential components. The hardening accelerator consists of one or >=2 kinds of the compds. expressed by the formula I which are incorporated therein at 0.5 to 63.0wt.%. The hardening accelerator is formed of 2,5-bishydroxy methylfurane, 2,5-bismethoxy methylfurane and 2,5-bisethoxy methylfurane alone or in combination. As a result, there is no need for increasing the amt. of the harclener or using hardeners of a sulfonic acid system, etc., having high acid intensity, etc., and, therefore, the production of the casting mold is executed in good working environment.
