Composite thermal insulation sand mold and preparation method thereof
The invention relates to a composite thermal insulation sand mold and a preparation method thereof. The composite heat preservation sand mold template is divided into three layers, the first layer is a high-temperature contact layer, the second layer is a heat conduction layer, and the third layer is a heat preservation layer. The main raw materials of the high-temperature contact layer are chromium oxide, alumina micro powder, magnesium oxide powder, silica powder, an aluminum dihydrogen phosphate solution and alumina sol. The main raw materials of the heat conduction layer comprise chromic oxide, alumina micro powder, magnesium oxide powder, silica powder, copper oxide powder and an aluminum dihydrogen phosphate solution. The main raw materials of the thermal insulation layer comprise chromic oxide aggregate, alumina micro powder, silica powder, hollow alumina balls, 1SQM300HB phenolic resin and a GS resin curing agent. The thickness of the high-temperature contact layer ranges from 15 mm to 35 mm, the thickness of the heat conduction layer ranges from 25 mm to 40 mm, and the thickness of the heat preservation layer ranges from 50 mm to 150 mm. The problems that a sand mold is insufficient in heat preservation capacity, and the outer surface temperature of a casting and the heat loss speed of the sand mold are too high are solved.
本发明涉及一种复合保温砂型及其制备方法。复合保温砂型模板分为3层，第一层为高温接触层，第二层为导热层，第三层为保温层。高温接触层主要原料为氧化铬、氧化铝微粉、氧化镁粉、硅微粉、磷酸二氢铝溶液，铝溶胶。导热层的主要原料有氧化铬、氧化铝微粉、氧化镁粉、硅微粉、氧化铜粉、磷酸二氢铝溶液。保温层的主要原料有氧化铬骨料、氧化铝微粉、硅微粉，空心氧化铝球，1SQM300HB酚醛树脂，GS树脂固化剂。高温接触层厚度范围为15mm‑35mm，导热层厚度范围为25mm‑40mm，保温层厚度范围为50mm‑150mm。采用本发明解决了砂型模具自身保温能力不足的问题，铸件外表面温度及砂型热量散失速度过快的问题。
