Description
技术领域
本发明涉及汽车清洁护理浓缩乳液合成技术,尤其涉及一种微水洗车和护理具有除醛杀菌作用精华素合成及制备方法。
背景技术
众所周知,洗车对于水资源的消耗较大, 一般的汽车美容店每洗一辆车要耗去50-100 公升以上水,主要的洗车流程包括 :准备、接车、冲车、打泡沫、 擦车外部、擦车内部、检查等七个环节。首先现有市场大部分洗车专门店采用强碱性高泡去污剂洗车甚至使用一些高泡洗衣粉开水,这样虽然成本低且能快速去污,但不会考虑漆膜的养护,长期使用会加速车漆快速老化、失色、龟裂、 生锈等,这些状况也是车主们容易忽视的。其次使用高压枪水洗车会对车体造成一定的影响,不利于车的长期保养。此外由于在人们长期错误的传统观念影响下,一直以来误认了采用大量水冲擦方式洗车较为干净,这其实是一个很大的误区,既浪费水也浪费金钱。再是汽车内部使用器件和装饰材料可能会带来醛类、苯类等挥发性有害气体,还有车内外细菌,都会损害驾乘人员健康,目前市面上具有除醛、苯挥发性气体、杀菌作用的洗车养护产品也是空白。
从以上几点来看,洗车的不正常现象必须改革。以往,由于技术上和其它原因使一些简单的节水洗车技术未能得到有效推广,并且某些无水洗车设备较为昂贵, 因而未得到认同。随着现代高新科技产品的不断涌现以及科学技术的不断发展,可发明一种将化学清洗和物理清洗相结合,对汽车进行清洁、 打蜡、 上光、养护一次完成的新型汽车清洁护理方式。这类方法的优势是整个洗车过程中简单方便、自己可解决、无需任何附加设备、对水消耗极少、清洗去污效果较佳,同时能够适合各种环境对车辆清洗,可节省车主大量时间。通过以上分析,需要对现有技术进行有效创新。目前也有微水洗车的产品,如CN 102586036A提供了一种节约水资源,能使污迹与漆面自动分离,上光效果绝佳,内饰清洁效果好,能够保持清洁面原有自然特性与活力,有利于节约洗车成本的非水洗式洗车精华素及其制备方法。但此方法使用的具有保护漆膜与抛光作用的水性蒙旦蜡,用于表面上光的二甲基硅油,这些都是惰性成分,不具反应活性,汽车清洁后在表面附着力差,作用时效短等缺陷,也不具备除去醛类、苯类挥发性有害气体、杀菌功能。
发明内容
针对现有技术中所述缺陷,本发明提供一种有利于节约洗车成本的汽车清洁护理除醛杀菌精华素合成技术及制备方法。
为实现上述目的, 本发明采用以下技术方案 :
本发明所述汽车清洁护理除醛杀菌精华素由20-40wt%的八甲基环四硅氧烷或二甲基硅氧烷混合环体、3-8wt%的四甲基四氢环四硅氧烷、0.3-0.8wt%的聚氧乙烯月桂醚、4-9wt%的磺酸、30-50wt%的去离子水、0.4-1wt%氢氧化钠、6-10wt%十二烷基硫酸钠、1-3wt%锐钛矿型纳米二氧化钛组成,按质量百分比称取八甲基环四硅氧烷或二甲基硅氧烷混合环体、四甲基四氢环四硅氧烷、聚氧乙烯月桂醚加入能加热带高速搅拌分散设备乳化罐中,加热40~50℃高速分散混合,按质量百分比称取磺酸和去离子水加入到另一个能加热带搅拌设备容器中,加热至70~80℃使磺酸充分溶解,冷却后,用耐酸蠕动泵将溶解好的磺酸水溶液滴加到乳化罐中,滴加完毕后,常温继续搅拌反应8小时,再滴加氢氧化钠水溶液进行中和至乳液pH6后,再加入十二烷基硫酸钠和锐钛矿型纳米二氧化钛搅拌均匀即为汽车清洁护理除醛杀菌精华素。
本发明进一步所述磺酸为十二烷基磺酸。
本发明所述锐钛矿型纳米二氧化钛可以是固态粉末,也可以是水性乳液。
本发明所述本发明汽车清洁护理除醛杀菌精华素为了利于保存,汽车清洁护理除醛杀菌精华素体系PH值为弱酸性。
本发明汽车清洁护理浓缩乳液稀释后添加助剂对汽车清洁时,能使污迹与漆面自动分离,清洁后能较长时间保持汽车外表面能疏水自洁,能够保持清洁面原有自然特性与活力,光泽度好,保护汽车免受紫外线和空气中有害成分损害。对汽车内部清洁护理后,留存的活性成分可以光催化醛类、苯类挥发性气体分解,光催化杀菌,减少对人体伤害,保障身体健康。
本发明所述使用方法是用合成的乳液加水稀释100~200倍,用喷雾器具喷雾汽车要清洗的部位,表面活性剂成分能使污迹与漆面自动分离,稍许用吸污毛巾擦拭脏污,吸附在待清洗部位的残留乳液渐渐发生交联反应,形成一层非常薄的有机硅膜,该有机硅膜能疏水自洁,能够保持清洁面原有自然特性与活力,对汽车护理时效长,光泽度好,保护汽车免受紫外线和空气中有害成分损害。留存的锐钛矿型纳米二氧化钛可以在光照下催化甲醛等醛类、苯类挥发性有害气体分解矿化为无机小分子、CO2和H2O等物质,杀灭细菌,降低对家乘人员身体伤害。
进一步本发明所述汽车清洁护理除醛杀菌精华素稀释100~200倍时,汽车清洁护理除醛杀菌精华素体系酸碱性接近中性,残留乳液里硅氢基可以脱氢交联形成有机硅膜。
进一步本发明所述汽车清洁护理除醛杀菌精华素使用后留存的锐钛矿型纳米二氧化钛在光的作用下具有催化作用,分解醛类、苯类、细菌等。锐钛矿型纳米二氧化钛本身具有高稳定性、耐光腐蚀、无毒等特点,并且在处理过程中不产生二次污染;有机污染物能被氧化降解为CO2和H2O,并且其对人体无毒。
所述八甲基环四硅氧烷(D4),无色透明或乳白色液体,可燃,无异味,是一种以二甲基二氯硅烷经过水解合成工序制得的产物基础上经过分离、精馏而得到的化合物。是有机硅行业的重要中间体。主要用途包括制备甲基硅油等有机硅高聚物,无线电零件绝缘和防潮,气相色谱玻璃毛细管柱表面去活性剂等。
进一步本发明所述分步合成方法为:按质量百分比称取八甲基环四硅氧烷(D4)或二甲基硅氧烷混合环体(DMC)、四甲基四氢环四硅氧烷(D4H)、聚氧乙烯月桂醚(OE-10)加入能加热带高速搅拌分散设备乳化罐中,加热40~50℃高速分散混合。另按质量百分比称取磺酸和部分去离子水加入到另一个能加热带搅拌设备容器中,加热至70~80℃使磺酸充分溶解,冷却后,用耐酸蠕动泵将溶解好的磺酸水溶液滴加到乳化罐中,滴加完毕后,常温继续搅拌反应8小时,再滴加氢氧化钠水溶液中和至乳液pH=6,加入十二烷基硫酸钠(K12)和锐钛矿型纳米二氧化钛搅拌均匀即为汽车清洁护理除醛杀菌精华素。
本发明有益效果:将本发明合成汽车清洁护理除醛杀菌精华素加普通水稀释100~200倍,用喷雾器具喷雾汽车要清洗的部位本产品喷上后会快速渗透, 有效使污渍与车漆产生间隙, 在沙土颗粒和车漆之间形成保护层, 同时沙子和污渍在表面活性剂作用下从漆面往下滑流的现象,这时使用吸污毛巾轻轻一抹, 沙子和污渍即粘附在毛巾上,不会划伤车漆,残留在车体表面乳液,脱氢发生交联反应形成一层疏水性有机硅质保护膜,使车膜亮丽照人,有效抵挡雨、雪、风、沙等对车体的伤害,并保护车漆镜面光泽不受损坏。留存锐钛矿型纳米二氧化钛在光的作用下具有非常强催化作用,可以分解甲醛、苯等挥发性有害气体,杀灭细菌,降低对家乘人员身体伤害。
