High-temperature sealing rubber mat for continuous casting protective casting as well as preparation method and application of high-temperature sealing rubber mat
The invention provides a high-temperature sealing rubber mat for continuous casting protective casting and a preparation method and application thereof.The preparation method comprises the following steps that 1, high-aluminum clinker, clay, graphite powder and metal aluminum powder are taken as raw materials and crushed and ground respectively to obtain raw material powder with different granularities; wherein in the obtained raw material powder, the granularity of the high-aluminum clinker and the clay is not higher than 200 meshes, the granularity of the graphite powder is not higher than 1000 meshes, and the granularity of the metal aluminum powder is not higher than 150 meshes; 2, uniformly mixing the ground and crushed high-aluminum clinker, clay, graphite powder and metal aluminum powder according to the weight percentage of (76-83): (4-7): (10-14): (1-3) to obtain solid-phase sealing powder A; 3, uniformly mixing epoxy resin, phenolic resin, water glass and zirconium oxide sol according to the weight percentage of (40-55): (10-15): (20-25): (15-20) to serve as a liquid-phase binder B; 4, uniformly mixing A and B according to the weight percentage of (68-72): (28-32); and 5, placing the mixed sample in a pressing mold on which oil-proof paper is laid, and carrying out compression molding to obtain the high-temperature sealing rubber mat.
本发明提供了一种连铸保护浇铸用高温密封胶垫及其制备方法和应用，采用如下步骤：1、取高铝熟料、粘土、石墨粉及金属铝粉为原料，分别破碎研磨处理得不同粒度原料粉体；其中，获得原料粉体中，高铝熟料和粘土粒度不高于200目，石墨粉不高于1000目，金属铝粉不高于150目；2、将研磨破碎的高铝熟料、粘土、石墨粉及金属铝粉按重量百分比76‑83：4‑7：10‑14：1‑3进行均匀混料获得固相密封粉A；3、将环氧树脂、酚醛树脂、水玻璃及氧化锆溶胶按重量百分比40‑55：10‑15：20‑25：15‑20进行均匀混合作为液相粘结剂B；4、将A与B按重量百分比68‑72：28‑32进行均匀混料；5、将混合好的样品置于铺好防油纸的压制模具中进行压制成型，获得高温密封胶垫。
