Abstract

PURPOSE: A mold sand collapsing agent of good collapsing property which is obtained by mixing powdery and granular petroleum-base wax, animal- and vegetable- base wax, etc. as well as powdery and granular seed residues etc. after extraction of oil components at the specific ratios.
CONSTITUTION: 100pts.wt. of one or two or more kinds of powdery and granular petroleum-base wax, animal- and vegetable-base wax, low molecular weight polyolefin resin, atactic polypropylene resin, etc. as well as 5W100pts.wt. of one or two or more kinds of powdery and granular coffee extraction residues, rapeseed-, sesame-, soya bean-, peanut, corn-, cocoa-oil-components extraction residues, etc. are mixed. For example, 100pts.wt. of powdery and granular petroleum-base wax and 45pts.wt. of dehydrated and dried powdery and granular coffee-extraction residues are mixed to prepare the collapsing agent. Next, 100pts.wt. silica sand, 1.2pts.wt. the collapsing agent, 6pts.wt. water glass and 1.5pts.wt. hardener are used to make a mold. These make is possible to obtain the mold of good collapsing property and make it easy to mold the mold.
