Abstract
本发明公开了一种无机耐高温涂料及其配制方法，以低成本的铝矾土、碳化硅、白泥构成，以水玻璃作为溶剂和粘结剂，搅拌均匀静置即可使用。本发明涂料既具有良好的耐高温抗氧化性，又具有良好的自剥性，可广泛应用于对装配尺寸有要求的热处理件上。
Description
本发明涉及无机非金属涂料，特别涉及一种无机耐高温涂料及其配制方法。
目前，冶金行业一般对耐高温涂料追求的效果是耐高温、耐氧化，并且不易剥落，如中国专利CN9610905.3“耐高温涂料及其生产方法”以及中国专利CN89107740.5“耐高温抗氧化涂料”介绍的就是这种涂料，一般应用于石墨电极、吹气管、渣口、钢钎等部件上。然而在热处理行业，一般部件对涂料的要求是在进行热处理时要耐高温抗氧化，但热处理过后，希望涂料易剥落，便于加工。例如，对于炼钢连铸辊和热轧输送辊进行堆焊修复时，堆焊后需对焊层进行退火处理，为防止焊层、轴头氧化(轴头氧化后，难以满足装配尺寸)，在辊子和轴头表面涂抗氧化涂料，为便于进一步堆焊和保证轴头尺寸，希望该涂料在热处理时抗氧化性能要好，处理过后在室温状态下有很好的自剥性。日本专利JP59-184781介绍了一种易剥落的抗氧化涂料，但由于其气密性差，抗氧化效果不够突出。
本发明的目的在于提供一种既耐高温抗氧化，且又有很好自剥性的无机耐高温涂料及其配制方法。
本发明的目的是通过下述方法实现的：利用铝矾土、碳化硅作为骨料，加入白泥，再加入水玻璃作为粘结剂，该无机耐高温涂料的主要成份组成的重量比为：
铝矾土 25-35份
碳化硅 10-18份
白泥 6份
水玻璃 45-55份(玻美度40)
本发明涂料的配制方法简单：将铝矾土、碳化硅与白泥混合均匀，再加入水玻璃作为粘结剂搅拌均匀静置即可。
部件热处理前，应先去油处理，再刷涂一层本发明涂料，经2-6小时晾干即可。
本发明涂料的有益效果是：由于采用铝矾土和碳化硅作为骨料，使得该涂料即具有良好的耐高温抗氧化性，又具有良好的自剥性，而且其配制和涂覆工艺简单易行。
为检验本发明涂料的耐高温抗氧化效果，我们选取试样进行涂覆涂料和不涂覆涂料热处理对比试验，试验结果见表1。
表1
| 试编 | 涂料类型 | 热处理工艺 | 原试样厚度mm | 去氧化皮后mm | 氧化皮厚 |
| 1-1 | 未涂 | 980℃*2h | 24.1 | 23.3 | 0.80mm |
| 1-2 | 本发明涂料 | ″ | 24.2 | 24.05 | 0.15mm |
本发明用于炼钢连铸辊前后轴头热处理抗氧化生产工艺实施如下：
实施例1、首先取27份铝矾土、15份的碳化硅、6份的白泥、52份玻美度40的水玻璃混合搅拌均匀静置，炼钢连铸辊前后轴头在涂覆前必需进行去油处理，再刷涂一层本发明涂料，3小时后进行热处理650℃*10小时空冷。
实施例2、首先取30份铝矾土、15份的碳化硅、6份的白泥、49份玻美度40的水玻璃混合搅拌均匀静置，炼钢连铸辊前后轴头在涂覆前必需进行去油处理，再刷涂一层本发明涂料，4小时后进行热处理650℃*10小时空冷。
经本发明涂料涂覆后炼钢连铸辊前后轴头热处理前后尺寸变化见表2。
