Water-soluble core mold material and preparation method thereof
The invention discloses a water-soluble core mold material and a preparation method thereof, and relates to the technical field of core mold material preparation. The water-soluble core mold material is prepared from the following components in parts by weight: 350 to 450 parts of quartz sand and 50 to 70 parts of binder glue solution, and the adhesive glue solution is formed by compounding a carboxylated PVA (Polyvinyl Alcohol) 1780 solution and a PVA 2488 solution. According to the preparation method disclosed by the invention, the carboxylation modified PVA1780 and PVA2488 are compounded to prepare the core mold material, and the excellent water solubility of the carboxylation PVA1780 and the better thermodynamic property of the PVA2488 are combined, so that the water-soluble core mold material which is compatible and adjustable in water solubility and high-temperature mechanical strength is obtained; and compared with a water-soluble core mold prepared from single polyvinyl alcohol, the water-soluble core mold has higher high-temperature mechanical strength and water solubility.
本申请公开了一种水溶性芯模材料及其制备方法，涉及芯模材料制备技术领域。一种水溶性芯模材料，按重量份计，包括以下组分：石英砂350份‑450份和粘结剂胶液50份‑70份；粘结剂胶液由羧基化PVA1780溶液和PVA2488溶液复配而成。本申请将羧基化改性的PVA1780和PVA2488复配来制备芯模材料，把羧基化PVA1780的优异的水溶性和PVA2488的较好的热力学性能相结合，从而获得了一种水溶性和高温力学强度兼容并且可调的水溶性芯模材料，且具有比单一聚乙烯醇制备的水溶性芯模更高的高温力学强度和水溶性能。
