一种阀门润滑脂及其制备方法
技术领域：
本发明涉及润滑脂技术领域，具体涉及一种阀门润滑脂及其制备方法。
背景技术：
阀门润滑脂是一种橡胶、塑料润滑剂，即使应用在温度、湿度变化很大的场合，也可长效润滑，专用于阀门的润滑及密封。在高温下不会碳化也不会蒸发，暴露在高温下也不会熔化或硬化。不溶于水、甲醇、乙醇、乙二醇及，耐水合物、无机盐、稀酸及碱性物质，不受矿物油、植物油、有机化合物及多种气体的影响。目前，所使用的大多为密封润滑脂，主要用于各种气体、液体介质的密封，同时也进行润滑，但不及阀门润滑脂的用途广泛。
发明内容：
本发明所要解决的技术问题在于提供一种耐腐蚀性、稳定性强且兼具润滑密封效果的阀门润滑脂及其制备方法。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种阀门润滑脂，由如下重量份数的原料制成：
石蜡油50-60份、羊毛醇15-20份、凹凸棒土10-15份、萜烯树脂8-12份、蜡助剂6-10份、松香酸聚氧乙烯酯6-10份、海藻酸钠5-8份、顺丁橡胶4-6份、石棉粉3-5份、田菁胶3-5份、聚丙烯酸钠2-4份、肥皂粉1-2份、尿素1-2份、稀土0.1-0.2份。
所述蜡助剂由如下重量份数的原料制成：巴西棕榈蜡15-20份、微晶蜡10-15份、乳化硅油10-15份、羟乙基纤维素7-10份、卡波树脂5-8份、月桂醇聚氧乙烯醚4-7份、鲸蜡醇3-5份、硫化猪油2-3份、丁苯橡胶1-2份、聚乙二醇5-10份、丙三醇10-15份，其制备方法为：先将巴西棕榈蜡和微晶蜡混合加热至完全熔化，再加入卡波树脂、丁苯橡胶和丙三醇，混合均匀后于微波频率2450MHz、功率800W下微波处理10min，然后加入乳化硅油和鲸蜡醇，继续微波处理5min，待混合物自然冷却至室温后加入羟乙基纤维素、月桂醇聚氧乙烯醚、硫化猪油和聚乙二醇，充分混合均匀。
一种阀门润滑脂的制备方法，包括如下步骤：
(1)将蜡助剂加入石蜡油中，分散均匀后再加入羊毛醇和顺丁橡胶，然后加热至80-90℃保温混合15min，即得物料I；
(2)将凹凸棒土和石棉粉充分混合，先置于100-110℃中干燥12h，再于300-350℃下煅烧3h，即得物料II；
(3)向物料I中加入物料II、萜烯树脂和田菁胶，然后加热至120-130℃保温混合20min，再加入松香酸聚氧乙烯酯、海藻酸钠、聚丙烯酸钠、肥皂粉、尿素和稀土，充分混合均匀即可。
本发明的有益效果是：本发明以石蜡油和羊毛醇为主要原料，辅以多种助剂制得阀门润滑脂，该润滑脂粘度适宜、稳定性好，可对阀门起到密封、润滑、防腐蚀的作用，延长使用寿命，适用于阀门中一些冲击振动部位和旋转密封部位，可起到其它材料无法比拟的作用。
