Abstract:

This invention relates to foundry binder systems, which cure in the presence of sulfur dioxide and an oxidizing agent, comprising (a) an epoxy resin; (b) an ester of a fatty acid; (c) a fluorinated acid, preferably hydrofluoric acid; (d) an effective amount of a oxidizing agent; and (e) no ethylenically unsaturated monomer or polymer. The foundry binder systems are used for making foundry mixes. The foundry mixes are used to make foundry shapes (such as cores and molds) which are used to make metal castings, particularly ferrous castings.

Filed:

Jul 5, 2007
Appl. No.:

11/825176
Inventors:

Xianping Wang - Dublin OH, US
H. Randall Shriver - Columbus OH, US
Jorg Kroker - Powell OH, US
Assignee:

Ashland Licensing and Intellectual Property, LLC - Dublin OH
International Classification:

B22C 3/00
B22C 1/22
C08K 5/54
US Classification:

523139, 164 16, 164138, 524730, 524731
Abstract:

This invention relates to a process for making foundry shapes (e. g. cores and molds) using epoxy-acrylate cold-box binders containing an oxidizing agent and elevated levels of an organofunctional silane, which are cured in the presence of sulfur dioxide, and to a process for casting metals using the foundry shapes. The metal parts have fewer casting defects because the foundry shapes made with the binder are more resistant to erosion.

US Patent:

20140190648, Jul 10, 2014
Filed:

Jul 19, 2012
Appl. No.:

14/232343
Inventors:

Xianping Wang - Dublin OH, US
Douglas J. Desmit - Greenwood IN, US
Joerg Kroker - Powell OH, US
Assignee:

ASK CHEMICALS L.P. - Wilmington DE
International Classification:

B22C 9/12
B22C 9/02
US Classification:

164 16, 164159
Abstract:

A “cold box” process for forming a foundry shape by curing a binder in a foundry mix operates by sequentially introducing a first vaporous curing catalyst to a pattern containing the formed foundry mix, followed by introducing at least a second vaporous curing catalyst. By arranging the amounts of the respective vaporous curing catalysts and the contact times, as well as by using the less active vaporous curing catalyst first, the total amount of curing catalyst used to effect the cure is reduced. Carrier gas may be used with the respective vaporous curing catalysts. Typically, the vaporous curing catalysts are tertiary amines having between three and six carbon atoms.
