Abstract

The invention discloses a wax material for a high-precision lost-wax process. The wax material is prepared from, by mass, 70-90% of fully-refined immobilized paraffin, 3-8% of beef tallow, 8-12% of purified beewax and 3-7% of glycerol ester of rosin. A preparing technology of the wax material for the high-precision lost-wax process is completed through the steps of beewax purification and material mixing. By adding the purified beewax and glycerol ester of rosin, compared with a traditional formula of single paraffin or paraffin and beef tallow, the formula has the advantages that the wax material is high in melting point and density degree centigrade, good in forming stability and small in number of air holes, and can be effectively applied to the high-precision lost-wax process casting technology.

Description

technical field [0001] The invention belongs to the field of wax material preparation, and in particular relates to a wax material used in a high-precision lost wax method and a preparation process thereof. Background technique [0002] The lost wax method is a method of metal casting, also known as investment casting in modern precision casting. The specific method is to make a casting mold with wax, apply the molding material externally, pour liquid metal into the whole casting mold, heat the casting mold to melt the wax, form a cavity casting mold, and obtain a shaped casting after cooling. In the conventional method, the casting mold made of the casting wax material used is not high in precision and poor in strength, and the casting mold making procedure is relatively complicated, which cannot meet the increasingly higher requirements of the modern mold industry. Contents of the invention [0003] The object of the present invention is to address the deficiencies of t...
