Description

一种新型石油科研仪器用保护防锈剂 技术领域
本发明涉及橡塑制品技术领域，特别涉及一种新型石油科研仪器用保护防锈剂。
背景技术
各种冷轧、热轧钢铁板材、一些金属箔材及一些机械设备制作完成后为防止较快产生锈蚀，一般都要在其表面涂一层防锈物质，以保护金属在使用前不发生锈蚀，影响其质量和价值，另一方面该保护层还可对金属表面起到一定的防护作用，防止轻微的划伤。目前金属板、箔材及钢铁机械设备部件的短期防锈都是涂一层防锈油或防锈蜡物质。防锈油虽有良好的短期防锈效果。但为油性物质，在后期使用前的清洗处理时会产生环境污染，为此人们开展了水基防锈剂的研究开发，水基防锈剂一般不含或少含油性物质，清洗处理容易方便，产生的废水少，且易处理。因而水基金属防锈剂近期年来是该领域广泛研究的课题，发明的新产品和新技术也比较多。CN1386812A公开了一种汽车用液体防锈蜡，该专利使用传统方法，用溶剂油溶解各种所需成分，产品虽然有一定的防锈性能，但由于含有溶剂油，使用时有溶剂气味发生，存在对环境不友好的缺陷。CN1488699A公开了一种水基金属防锈保护剂，由于产品中使用了石油磺酸钡成分，使产品有一定的毒性。CN101104774A公开了一种金属防锈蜡，以蜡类物质为主要基础物质，产品的防护膜没有韧性。CN1386812A公开了一种防锈 剂，主要成分是石油蜡类物质及石油溶剂，防锈性能及其它性能存在缺陷，并对环境不友好。
发明内容
本发明要解决的技术问题是提供一种防锈效果良好、在金属表面涂抹粘附容易的新型石油科研仪器用保护防锈剂。
为解决上述技术问题，本发明的技术方案为：一种新型石油科研仪器用保护防锈剂，其创新点在于：按重量分数配比由以下组分制成：
蜡类物质11-17份，云母氧化铁50-55份，树脂3-8份，聚酰胺固化剂5-10份，脂肪酸11-13份，醇酸防锈漆50-80份，脂肪胺2-4份，钴锰稀土10-15份，金属缓蚀剂5-11份，环烷酸锌2-3份，表面活性剂1-9份，异丙醇12-28份，丙酮13-24份，三乙醇胺2-5份，苯并三氮啜1-4份。
进一步的，所述蜡类物质是分子量为1000-2000的氧化聚乙烯蜡、80-85号氧化微晶蜡、60-70号氧化石蜡中的一种或几种。
进一步的，所述树脂是软化点为70-100℃的石油树脂、松香树脂、改性松香甘油酯中的一种或几种。
进一步的，所述牛皮纸层的厚度是所述铝箔层的1.4-2倍。
进一步的，所述脂肪酸为长链饱和脂肪酸，具体是硬脂酸和/或软脂酸。
进一步的，所述脂肪胺是丁二胺、己二胺、己胺、正辛胺、异辛胺、葵胺中的一种或几种。
进一步的，所述金属缓蚀剂是双咪唑啉季铵盐、十七烯基双咪唑 啉季铵盐、油酸基咪唑啉中的一种或几种。
本发明的优点在于：本发明选用蜡类物质和树脂做防锈剂的成膜物质，其特点是蜡类物质本身具有一定的疏水性，树脂有一定的韧性或塑性，可使防锈保护膜具有一定的疏水性和强度，并使防锈物质与目标物件表面形成良好的吸附保护层，阻止或减缓酸、碱、盐物质对物件的浸蚀。选用咪唑啉铵盐类物质作防锈物质，因该类物质无毒或毒性小，对环境友好，使产品无毒无味。该防锈保护剂涂附钢铁金属表面上，可在目标物件上形成有一定韧性和强度的吸附防锈保护膜，克服了一般水基防锈剂对金属涂抹粘附困难的缺陷，又具有金属后处理时清洗方便的特点。选用脂肪酸与脂肪胺水溶液反应制成具有凝胶体性能的物质，再与其它油相物质乳化获得最终产品，可以保证该产品在高温下仍具有较好粘附性，可在金属、箔材和其它金属机械设备部件涂附时反复升温使用，克服了一般乳液产品或常用的防锈油产品在温度较高时不能涂附或不易涂附的缺陷。
本发明的防锈剂可以在设备表面形成一层防锈膜，附着力强，耐压性能良好，不仅防水防锈，而且还起到防腐的保护作用，也具有对设备形成良好的保护，提高设备的性能指数，延长了使用寿命。
