本发明提出的一种环保高性能醇酸树脂，包括：按重量份将13-17份地沟油、3-6份酸化油、以酸化油为基准45-65wt％三羟甲基丙烷、7-8.5份PAT水池料、13-17份涤纶废丝及以地沟油与酸化油总量为基准35-43wt％甲基硅油投入反应釜中，升温至245-248℃进行点动搅拌，至点动搅拌没有阻力时开启搅拌并以1-3℃/min升温速度升温至275-282℃进行保温得到中间料，上述过程中将料液中的水不断采用油水分离器分出，检测中间料的粘度为200-220s/25℃(涂-4)，检测中间料的酸价为≤10mgKOH/g；将2-4份偏硼酸锌与3-6份改性高岭土置于研磨机中高速分散研磨得到A物料，其中改性高岭土采用偶联剂KH-171进行改性，将中间料以4-6℃/min降温至240-245℃以下，加入A物料与甲基硅油为基准85-95wt％固体石油树脂与A物料搅拌2-5min，将得到的料液抽往含芳烃的兑稀釜中进行搅拌，芳烃与甲基硅油的重量比为25-30:5-8，搅拌过程中采用冷却水对兑稀釜冷却，冷却速度为10-14℃/min，待物料冷却至40-50℃时用芳烃调整兑稀釜内粘度为200-400s/25℃，过滤后得到环保高性能醇酸树脂。
优选地，按重量份将14-15份地沟油、3.5-4.2份酸化油、以酸化油为基准48-52wt％三羟甲基丙烷、7.5-8份PAT水池料、14-16份涤纶废丝及以地沟油与酸化油总量为基准38-39.5wt％甲基硅油投入反应釜中。
优选地，关闭人孔升温至246-247℃进行点动搅拌，至点动搅拌没有阻力时开启搅拌并以1.5-2℃/min升温速度升温至278-280℃进行保温得到中间料。
优选地，将中间料以4-6℃/min降温至243-244℃以下，开引风机，开人孔，加入A物料与甲基硅油为基准92-94wt％固体石油树脂搅拌2-3min。
优选地，芳烃与甲基硅油的重量比为26-28:6-8，搅拌过程中采用冷却水对兑稀釜冷却，冷却速度为13-14℃/min，待物料冷却至45-48℃时用芳烃调整兑稀釜内粘度为200-400s/25℃。
本发明中，上述环保高性能醇酸树脂有效解决了一些食品厂及日常生活产生的地沟油难处理、难回收问题，涤纶纺丝行业涤纶废丝脚料难回收、难处理问题，以及涤纶上游产品PTA在生产包装及运输过程中产生废料的难回收问题，变废为宝被充分利用，上述醇酸树脂既减少了工业浪费及缓解了一些工业废料难处理给环境造成的压力，又大幅度降低了涂料用成膜物质的成本，且制备工艺简单，大大降低了生产成本，且其干性良好，偏硼酸锌可阻挡水汽及其它腐蚀气体渗进涂膜或者具有化学抑制作用，改性高岭土可改善涂膜的耐磨、附着力、耐热性及增加涂膜厚度，增强涂膜的防腐效果，甲基硅油具有抗浮色、消泡作用，改善流挂的功能，偏硼酸锌、改性高岭土及甲基硅油配合作用，制品性能极为优异，成本低，且比传统389树脂具有更高的硬度、光泽度及丰满度，用于生产一些室内防腐涂料具有很高的性价比。
