具体实施方式
下面结合实施例对本发明做进一步的详细说明,以令本领域技术人员参照说明书文字能够据以实施。
本案提出一种无磷清洗剂,其中,按重量份计,包括以下组分:
柠檬酸钠作为洗涤助剂,表面活性剂通过与渗透剂的配合,可以有效的提高清洗剂与污垢的接触表面,更好的溶解污垢,通过加入1,4-丁烷二磺酸,可以有效的去除金属制品表面的锈斑、油污等较为难去的污垢,通过加入缓蚀剂,既可以提高清洗剂在酸性环境下的去污能力,还能显著提高对金属的腐蚀抑制作用;2,4-二-(对氨基苯甲酸)-6-二乙胺基-1,3,5-三嗪作为乳化剂,进一步改善清洗剂的乳化清洗效果;丙二醇甲醚作为溶解剂,改善2,4-二-(对氨基苯甲酸)-6-二乙胺基-1,3,5-三嗪的互溶性能。
作为本案又一实施例,其中,表面活性剂包括20~30wt%烷基二甲基磺丙基甜菜碱、30~40wt%1-羧甲基脂肪基咪唑啉和30~40wt%棕榈油酰基谷氨酸钠。表面活性剂通过在气液两相界面吸附降低水的表面张力,也可以通过吸附在液体界面间来降低油水界面张力,本案优选的表面活性剂为烷基二甲基磺丙基甜菜碱、1-羧甲基脂肪基咪唑啉和棕榈油酰基谷氨酸钠协同作用,使得表面张力达到最小。
作为本案又一实施例,其中,螯合剂包括24~28wt%羧酸钠、30~34wt%三亚烷基四胺乳酸钾和40~44wt%柠檬酸二乙酯。螯合剂在含水组合物中仅具有低反应性且如果其在所用工艺条件下至少部分分解且释放出的金属离子用于成键或化学反应,那么这类螯合剂特别合适,从而使得清洗剂在金属铁表面形成一层稳定的保护膜,螯合剂优选具有亲水性、水解稳定性、水稳定性,形成稳定的水解产物或具有这些性质的任何组合,本案优选的螯合剂为羧酸钠、三亚烷基四胺乳酸钾和柠檬酸二乙酯协同作用。
作为本案又一实施例,其中,缓蚀剂选自1-羟乙基-2-油基咪唑啉、巯基苯骈噻唑和钼酸铋中的一种或多种。缓蚀剂显著提高对金属的腐蚀抑制作用,本案优选的缓蚀剂选自1-羟乙基-2-油基咪唑啉、巯基苯骈噻唑和钼酸铋。
作为本案又一实施例,其中,渗透剂包括40~44wt%仲烷基硫酸酯钠、20~24wt%氨基磺酸钠、30~36wt%N-苄胺苯二胺。渗透剂是起渗透作用,也是具有固定的亲水亲油基团,在溶液的表面能定向排列,并能使表面张力显著下降的物质,从而提高清洗剂的清洗效果,本案优选的清洗剂为仲烷基硫酸酯钠、氨基磺酸钠、N-苄胺苯二胺协同作用。
作为本案又一实施例,其中,消泡剂包括30~34wt%月桂酸咪唑啉、36~40wt%聚氧乙烯聚氧丙烯季戊四醇醚和24~28wt%己二醇。消泡剂降低表面张力,抑制泡沫产生或消除已产生泡沫,本案优选的消泡剂为月桂酸咪唑啉、聚氧乙烯聚氧丙烯季戊四醇醚和己二醇三者协同作用。
作为本案又一实施例,其中,还包括1~3份钛酸锆。钛酸锆是ZrTiO4为主晶相的陶瓷材料,主要原料为二氧化钛和二氧化锆,加入少量适宜添加物,采用一般电子陶瓷工艺,约1400℃烧成。高温下可形成ZrTiO4-TiO2和ZrTiO4-ZrO2两类固溶体,能显著提高对金属的腐蚀抑制作用,并可防止无磷清洗剂的光、热分解或氧化分解。
作为本案又一实施例,其中,还包括5~7份D-柠檬烯。D-柠檬烯作为分散剂,提高清洗剂的稳定性能。
作为本案又一实施例,其中,还包括2~4份1,4-丁烷二磺酸。通过加入1,4-丁烷二磺酸,可以有效的去除金属制品表面的锈斑、油污等较为难去的污垢。
作为本案又一实施例,其中,还包括0.5~1份茶皂素、0.5~1份环糊精和1~2份海藻酸钠。本发明采用茶皂素,其有良好的乳化、分解、发泡功能,能迅速去除油污,加入海藻酸钠可以增强清洗剂的渗透效率,二者协同作用,加入环糊精可以保持化学平衡,降低表面张力,防止光、热分解或氧化分解。
