Description

一种用于土壤温度传感器的保护漆及其制备方法
技术领域
本发明涉及水质监测领域，具体涉及一种用于土壤温度传感器的保护漆及其制备方法。
背景技术
土壤温度简称地温，是地表温度和地中温度的总称。土壤温度的高低，与作物的生长发育、肥料的分解和有机物的积聚等有着密切的关系，是农业生产中重要的环境因子。土壤温度也是小气候形成中一个极为重要的因子，故土壤温度的测量和研究是小气候观测和农业气象观测中的一项重要内容。
用问题传感器测量时，通常都是在被测土壤中人工挖出一个剖面，分层布设土壤温度传感器，然后用土填回。鉴于土壤的成分非常复杂，被掩埋的温度传感器表面要有很好的保护层，才能不容易损坏。因此，需要一种既不影响温度传感器的工作，又能保护传感器的保护漆。
发明内容
针对现有技术问题，本发明的目的在于提供一种用于土壤温度传感器的保护漆及其制备方法，该保护漆耐酸碱、质地稀薄，不会降低传感器的敏感度，且制备方法简单，便于产业化。
为解决现有技术问题，本发明采取的技术方案为：
一种用于土壤温度传感器的保护漆，包括以下按重量份数计的原料：油漆组分72-84份，碳纤维12-18份，玻璃纤维2-6份，乙酸3-8份，多聚磷酸铵15-19份，钛金属粉1-4份，甘油10-18份，酵母1-15份，醋酸丁酯1-4份，稀释剂1-5份，防冻剂1-3份。
作为上述用于土壤温度传感器的保护漆优选的是，包括以下按重量份数计的原料：油漆组分80份，碳纤维15份，玻璃纤维5份，乙酸5份，多聚磷酸铵16份，钛金属粉1份，甘油15份，酵母15份，醋酸丁酯3份，稀释剂4份，防冻剂1份。
作为上述用于土壤温度传感器的保护漆优选的是，还包括艾叶提取液2-8份。
上述用于土壤温度传感器的保护漆的制备方法，包括以下步骤：
步骤1，将碳纤维、玻璃纤维、钛金属粉混合后，用干冰破碎，加入乙酸、多聚磷酸铵、醋酸丁酯加热至1000-1800℃得第一混合物；
步骤2，向油气组分中加入甘油和酵母搅拌后用干冰粉碎，加入第一混合物中，搅拌后再加入稀释剂和防冻剂，调节粘度即得保护漆。
作为制备方法改进的是，步骤1中加热至1500℃。
作为制备方法改进的是，步骤2中调节粘度至100-200Pa•s。
有益效果
本发明保护漆耐酸碱能力强，质地稀薄，比重小，喷涂在温度传感器表面，既能保护传感器，又不影响测量的准确性，深受探测部门的喜爱。另外，本发明制备方法简单，易行，容易产业化。
