一种耐铝液腐蚀的高温玻璃涂料
摘要：
本发明公开了一种耐铝液腐蚀的高温玻璃涂料，其所用原料按重量百分数计为：A组分玻璃40-60%、B组分玻璃20-40%、硅线石0-10%、分散剂0-5%、高温粘结剂10-20%，上述各原料的重量百分数之和为100%；其中，A组分玻璃为软化温度高达750℃的高温玻璃，其由碳酸锶、碳酸钙、二氧化硅、硼酸、氧化铝为原料组成，B组分玻璃为流动性强的低温玻璃，其由氧化铝、硼酸、碳酸钠、氧化锌为原料组成。本发明高温玻璃涂料具有良好的耐腐蚀性，将该高温玻璃涂料喷涂或涂刷在搅拌头表面，并利用A、B组分玻璃的二次流平，可提高涂层的致密度，使搅拌头耐铝液腐蚀，有效延长其使用寿命，且其烧结温度低于800℃，施工方便。
摘要（英）：

The invention discloses a high-temperature glass coating material resistant to molten aluminum corrosion. The high-temperature glass coating material is prepared from the raw materials in percentage by weight: 40-60% of component glass A, 20-40% of component glass B, 0-10% of sillimanite, 0-5% of dispersant and 10-20% of high-temperature binder, wherein the sum of weight percent of all the raw materials is 100%, the component glass A is high-temperature glass, of which the softening temperature reaches 750 DEG C, and is prepared from strontium carbonate, calcium carbonate, silicon dioxide, boric acid and alumina, and the component glass B is low-temperature glass with high fluidity and is prepared from alumina, boric acid, sodium carbonate and zinc oxide. The high-temperature glass coating material disclosed by the invention has good corrosion resistance; through spraying or coating the surface of a stirring head with the high-temperature glass coating material and using the secondary leveling of the component glass A and the component glass B, the density of a coating can be improved, so that the stirring head is resistant to molten aluminum corrosion, and the service life of the stirring head is effectively prolonged; the sintering temperature is below 800 DEG C, so that the construction is convenient.
