Effect of Methyl Silicone Oil and Poly(vinyl Alcohol) On the Moisture Resistance of Ester-hardened Sodium Silicate Bonded Ceramic Sand
Sodium silicate binder as a binder for sand casting has the advantages of green, non-polluting, low cost, but the problem of strong hygroscopicity of sodium silicate bonded ceramic sand (SSBCS) has been pending solution. In this paper, the effect of methyl silicone oil and poly(vinyl alcohol) on the moisture resistance of ester-hardened SSBCS was studied, aiming to solve the problem of high moisture absorption of SSBCS. The results showed that the optimum ratio was 15% methyl silicone oil and 3% poly(vinyl alcohol). Compared with unmodified SSBCS, the moisture absorption rate of SSBCS modified by methylsilicone oil and poly(vinyl alcohol) at 2, 4, 6 and 8 h decreased by 0.2%, 0.18%, 0.32% and 0.51%, respectively, and the strength loss rate at 2, 4, 6 and 8 h decreased to 0. Characterization analysis concluded that methyl silicone oil and poly(vinyl alcohol) improved the strength of SSBCS by absorbing free sodium ions (Na+) from the sand and by covering the surface of SSBCS with a film to reduce water absorption.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
