Binder for shell mold and method for producing the same |
| abstract |
PROBLEM TO BE SOLVED: To provide a shell mold binder in which a core is prevented from cracking at the time of casting a light alloy, and furthermore, the generation of formaldehyde during the molding of the shell mold is suppressed. SOLUTION: The mass average molecular weight measured by gel permeation chromatography is 1000 or more, and the relative retention ratio to the phenol peak is 0.80 to 0.80. The ratio (I / II) of the peak height I of 0.81 to the peak height II of 0.75 to 0.79 is 1.0 or more, and the gel time at 150 ° C. according to JIS-K6910 is 30. It is a binder for shell mold mainly composed of bisphenol A-modified novolak phenol resin for up to 60 seconds. |
