本发明的技术目的是提供一种新包覆型缓蚀纳米粒子,把其加入环氧富锌-石墨烯涂料中,以此作为底漆涂装在经过机加工处理的铝合金车轮表面,改善铝合金车轮防腐的能力。
为了实现上述技术目的,提供如下的技术方案:
一种商用车车轮成型工艺,该成型工艺以A356合金棒料为原料,具体包括如下工艺步骤:加热、墩粗、旋转锻造、热冲孔、热旋压、热处理、机加工、涂装,所述涂装工艺使用环氧富锌-石墨烯涂料作为底漆,并且在环氧富锌-石墨烯涂料中加入有包覆型缓蚀纳米粒子,其具体制备方法如下:利用曼尼希反应机理,以含有芳环活泼氢的苯并三氮唑和甲醛及氨基官能团化负载单体同时发生胺甲基化反应,生成结构为负载有苯并三氮唑基团的缓蚀单体,其作为缓蚀剂、醋酸锌为锌源、2-甲基咪唑为有机配体,通过锌与2-甲基咪唑和缓蚀单体上氮原子之间的配位作用,把缓蚀单体包封固定在金属有机骨架ZIF-8的纳米容器内,制备得到包覆型缓蚀纳米粒子。
优选的,所述包覆型缓蚀纳米粒子包括:包覆型缓蚀纳米粒子CCIN-Ⅰ和/或包覆型缓蚀纳米粒子CCIN-Ⅱ。
优选的,所述缓蚀单体包括:缓蚀单体CIM-Ⅰ和/或缓蚀单体CIM-Ⅱ。
优选的,所述氨基官能团化负载单体包括:氨基官能团化负载单体L-M-Ⅰ和/或八氨基笼型倍半硅氧烷。
优选的,所述氨基官能团化负载单体L-M-Ⅰ的制备方法如下:以季戊四醇为联接基、3-氯丙胺盐酸盐为原料,通过亲核试剂季戊四醇的醇羟基官能团与3-氯丙胺盐酸盐的氯官能团发生亲核取代反应生成氨基官能团化负载单体L-M-Ⅰ。
优选的,所述涂装工艺包括如下步骤:
步骤S1,把X10稀释剂加入环氧富锌-石墨烯涂料中,得到底漆Ⅰ;
步骤S2,把包覆型缓蚀纳米粒子超声分散在底漆Ⅰ中,得到含有包覆型缓蚀纳米粒子的底漆Ⅱ;
步骤S3,利用喷枪把底漆Ⅱ喷涂在经过机加工处理的铝合金车轮表面上,其喷涂厚度为(85±5)µm;
步骤S6-4,喷涂结束之后,干燥固化得到铝合金车轮。
优选的,所述步骤S1,X10稀释剂用量为环氧富锌-石墨烯涂料的15-35wt%。
优选的,所述步骤S2,包覆型缓蚀纳米粒子的用量为3-10wt%。
优选的,所述步骤S3,喷涂分为三步,每一步喷涂20~30µm,并且每一次间隔3-10min。
与现有技术相比,本发明具备以下有益的技术效果:
利用曼尼希反应机理合成了负载有苯并三氮唑基团的新型缓蚀单体,以其为缓蚀剂、醋酸锌为锌源、2-甲基咪唑为有机配体,通过锌与2-甲基咪唑和缓蚀单体上氮原子之间的配位作用,把缓蚀单体包封固定在金属有机骨架ZIF-8的纳米容器内,制备包覆有缓蚀单体的包覆型缓蚀纳米粒子;
通过实验可知,包覆型缓蚀纳米粒子对A356合金具有较好的缓蚀效果,因此将包覆型缓蚀纳米粒子加入环氧富锌-石墨烯涂料,以此作为底漆涂装在经过机加工处理的铝合金车轮表面;
其中,包覆型缓蚀纳米粒子主要通过苯并三氮唑基团与铝表面发生吸附而起缓蚀作用,并且包覆型缓蚀纳米粒子CCIN-Ⅰ的缓蚀性能要优于包覆型缓蚀纳米粒子CCIN-Ⅱ,据此可知缓蚀单体的分子结构直接影响其缓蚀效率。
