Description

自发光道路标线涂料、制备方法及施工方法
技术领域
本发明涉及涂料、制备方法及施工方法，特别涉及自发光道路标线涂料、制备方法及施工方法。
背景技术
路标线广泛应用于各等级公路中，是交通出行和交通安全的重要组成部分，具有引导管制车辆在道路上安全行驶的作用。目前，市场中广泛使用的普通道路标线漆多为被动反光型，其在白天具备足够的逆反射系数，能够起到警示作用。但是在雨雾天气、夜间无光照射的情况下，普通标线涂料因不能反光而失去了警示的作用，容易发生交通事故。自发光标线涂料可以在白天光源充足的情况下通过吸收日间自然光、机动车辆及各类照明灯光光能储存光，到了夜间再自发光，而且能保持数小时之内持续发光。目前也有研究学者对这种长余辉的自发光标线涂料进行研究，但是所用涂料的树脂多位水性树脂，对施工条件要求比较苛刻，需要的养生时间也较长。工程应用中往往在涂料还没完全固化的情况下开放交通，导致标线涂料剥落。
发明内容
发明目的：本发明目的是提供自发光道路标线涂料、制备方法及施工方法，解决目前市面上普通道路标线涂料在夜间行车时无法辨认清楚的问题，替代市面上一些耐久性较差的自发光标线涂料。特殊的手持式微波加热施工方式能够促进自发光道路标线涂料的固化，使其粘结强度更高，开放交通更快。从而更加适于实用，且具有产业上的利用价值。
技术方案：本发明提供一种自发光道路标线涂料，包括如下重量份数的原料：自制聚氨酯改性丙烯酸树脂乳液25-40份，邻苯二甲酸二辛酯1-10份，蓄能自发光粉10-30份，钛白粉5-20份，滑石粉5-15份，玻璃微珠10-20份，纳米气相二氧化硅0.01-0.5份，分散剂0.5-2份，消泡剂0.5-2份，流平剂0.5-2份，增稠剂0.5-2份，自来水5-10份；
所述自制聚氨酯改性丙烯酸树脂乳液制备方法如下：
将1-5份OP-10乳化剂加入到30-50份水性聚氨酯乳液中搅拌均匀；然后同1-10份甲基丙烯酸、1-5份苯乙烯、1-8份丙烯酸丁酯和5-15份甲基丙烯酸甲酯加入带搅拌器的反应釜中，升温到60-90℃，打开搅拌器，逐滴加入0.1-2份引发剂，升温至80-100℃，保温2-4h出料。
进一步地，所述引发剂为过氧化苯甲酰、过氧化月桂酰、偶氮二异丁腈、过硫酸钠和过氧化苯甲酸叔丁酯中的任意一种。
进一步地，所述蓄能自发光粉是经过二氧化硅包膜处理后的稀土夜光粉。所述钛白粉细度为200-400目，滑石粉细度为100-200目，玻璃微珠细度为20-40目。所述分散剂采用5020分散剂。所述消泡剂采用BYK消泡剂。所述流平剂采用1154流平剂。所述增稠剂采用KG-201聚氨酯增稠剂。
所述的自发光道路标线涂料的制备方法，其特征在于：包括如下步骤：
(1)称取蓄能自发光粉放入容器中，加入邻苯二甲酸二辛酯搅拌均匀。
(2)将自制聚氨酯改性丙烯酸树脂乳液、分散剂、流平剂、引发剂、钛白粉、滑石粉、消泡剂、自来水和纳米气相二氧化硅放入搅拌器中搅拌均匀。
(3)将均匀的蓄能自发光粉加入搅拌器中，滴加适量增稠剂，调整粘度至合适的时候出料。
所述的自发光道路标线涂料的施工方法，其特征在于：现场喷涂，在道路标线施工完成后，撒上玻璃微珠，采用专用手持式微波加热标线。
有益效果：本发明的自发光道路标线涂料成膜物质采用的是自制的聚氨酯改性丙烯酸树脂乳液，不仅具有聚氨酯的柔性，有效防止标线涂料开裂，也具有丙烯酸树脂的高粘结强度，提高标线涂料的耐久性。本发明采用的稀土夜光粉经过包膜处理后在水性乳液中可以避免水对其余晖时间的影响，从而在夜间保持长时间的余晖。特殊的手持式微波加热施工方式能够促进自发光道路标线涂料的固化，使其粘结强度更高，开放交通更快。本发明采用的稀土夜光粉经过包膜处理后在水性乳液中可以避免水对其余晖时间的影响，从而在夜间保持长时间的余晖。特殊的手持式微波加热施工方式能够促进自发光道路标线涂料的固化，使其粘结强度更高，开放交通更快。
