Description

促进红外激光对陶瓷吸收能力的涂覆液及制备方法和应用 技术领域
本发明涉及一种促进红外激光对陶瓷吸收能力的涂覆液及制备方法和应用，适合激光对陶瓷类(氧化铝、氧化锆、氮化铝)划线和切割使用，亦可作为其他材料加工时的保护剂使用。
背景技术
激光作为一种新型的加工方式逐步取代一些传统机械加工方式，加工方向延伸到整个社会的各个领域，朝向高精尖的加工模式发展，既满足粗放型加工，又能兼顾精细类型的加工。
激光器内部通过一个光子激发其他光子，使大量光子以光束的形式一起发射出去，通过聚焦汇聚成一个很小的光斑，无需直接接触，即可与材料发生相互作用。当激光束透射在材料表面时，能量有时并不能完全被材料吸收，存在部分能量被反射，部分能量被吸收，部分被传递出去的可能，具体情况取决于材料类型和激光波长。在到达材料表面的光能中，被材料吸收的那部分能量对材料加工是有用的。尽管材料与材料间的相互作用基本相似，但不同材料如金属、陶瓷、玻璃和塑料各有各的特点。
目前加工陶瓷使用的红外波段的激光基本上有两种，中红外波长为10.6um的CO2激光器和近红外波长为1.06um的光纤激光器。因二氧化碳激光切割只能适合一些普通陶瓷切割，对于一些更高要求的陶瓷受到其本身光斑大，加工效率低的制约而无法展开，CO2激光器本身还存在一些缺陷，比如维护成本高，切割边缘不光滑等，虽然陶瓷在中红外的吸收率较高，但是随着科技进步和市场发展，加工的产品要求更加苛刻，使得无法 胜任当前的精细加工。在这种背景下，近红外波段的光纤激光器应运而生，因光斑小，光电转化效率高，功率稳定等高性能，逐渐应用在陶瓷加工行业方面。陶瓷在近红外波段的吸收率较低，激光加工陶瓷出现吸收率低、断光、加工效率低下等情况。
发明内容
本发明的目的是克服现有技术存在的不足，提供一种促进红外激光对陶瓷吸收能力的涂覆液及制备方法和应用，旨在解决近红外激光加工陶瓷吸收率不足的问题。

胭脂红     35％；
诱惑红     5％；
溶剂       60％；
更进一步地，上述的促进红外激光对陶瓷吸收能力的涂覆液，其中，所述诱惑红为6-羟基-5-(2-甲氧基-4-磺酸-5-甲苯基)偶氮萘-2-磺酸二钠盐。
更进一步地，上述的促进红外激光对陶瓷吸收能力的涂覆液，其中，所述胭脂红为1-(4’-磺酸基-1’-萘偶氮)-2-萘酚-6,8-二磺酸三钠盐。

再进一步地，上述的促进红外激光对陶瓷吸收能力的涂覆液的制备方法，其中，所述诱惑红为6-羟基-5-(2-甲氧基-4-磺酸-5-甲苯基)偶氮萘-2-磺酸二钠盐；所述胭脂红为1-(4’-磺酸基-1’-萘偶氮)-2-萘酚-6,8-二磺酸三钠盐；所述溶剂为水或者酒精。
本发明促进红外激光对陶瓷吸收能力的涂覆液的应用，基板平放在具有吸附孔的载台上，陶瓷板固定其上，使用无尘布蘸取涂覆液对陶瓷板表面进行涂覆。

附图说明
下面结合附图对本发明技术方案作进一步说明：
图1：实施例的吸收长度-波长曲线示意图。
具体实施方式
本发明促进红外激光对陶瓷吸收能力的涂覆液，组分的重量百分比为：胭脂红20～40％，诱惑红1～5％，溶剂55～75％。理想成分配比：胭脂红35％，诱惑红5％，溶剂60％。其中，胭脂红为1-(4’-磺酸基-1’-萘偶氮)-2-萘酚-6,8-二磺酸三钠盐；诱惑红为6-羟基-5-(2-甲氧基-4-磺酸-5-甲苯基)偶氮萘-2-磺酸二钠盐；溶剂为水或者酒精。
具体的制备工艺为：首先，将胭脂红、诱惑红按照组分配比混合搅拌均匀；然后，将混合粉体投入到器皿中，向器皿中加入溶剂进行调配，溶剂为水或者酒精，混合均匀；继而，将器皿加入磁子，放在磁力搅拌器上，磁力搅拌器具有加热温控装置，通过加热和磁子旋转搅拌方式，加热温度为40～50℃，使粉体均匀溶解，形成涂覆溶液。
促进红外激光对陶瓷吸收能力的涂覆液具体应用时，氧化铝基板平放在具有吸附孔的载台上，陶瓷板固定其上，使用无尘布蘸取涂覆液对陶瓷板表面进行涂覆。
实施例1
首先，将胭脂红24％、诱惑红1％按照组分配比混合搅拌均匀；然后，将混合粉体投入到器皿中，向器皿中加入75％水进行调配，混合均匀；继而，将器皿加入磁子，放在磁力搅拌器上，磁力搅拌器具有加热温控装置，通过加热和磁子旋转搅拌方式，加热温度为40～50℃，使得固体粉末更好的均匀溶解，形成涂覆溶液。
实施例2
首先，将胭脂红20％、诱惑红5％按照组分配比混合搅拌均匀；然后，将混合粉体投入到烧杯中，向烧杯中加入75％酒精进行调配，混合均匀；继而，将烧杯加入磁子，放在磁力搅拌器上，磁力搅拌器具有加热温控装置，通过加热和磁子旋转搅拌方式，加热温度为40～50℃，使得固体粉末更好的均匀溶解，形成涂覆溶液。
实施例3
首先，将胭脂红35％、诱惑红5％按照组分配比混合搅拌均匀；然后，将混合粉体投入到烧杯中，向烧杯中加入60％酒精进行调配，混合均匀；继而，将烧杯加入磁子，放在磁力搅拌器上，磁力搅拌器具有加热温控装置，通过加热和磁子旋转搅拌方式，加热温度为40～50℃，使得固体粉末更好的均匀溶解，形成涂覆溶液。
上述实施例1～3制得的涂覆溶液分别用于激光加工时涂覆陶瓷板，将白色氧化铝基板依次平放在带有吸附孔玻璃载台上，使用无尘布蘸取上层溶液对陶瓷表面进行单向涂覆；涂覆好的基板采用激光系统对其进行切割、划线等方面的加工，未出现断光、漏线等现象。对加工完成的样品进行清洗，去除陶瓷表层的粉体。
从图1的吸收长度-波长曲线，可以表明增加诱惑红和胭脂红在溶液中的比重能够提高红外波长对其吸收度，促进红外激光对吸收剂涂抹后的吸收性能。
涂覆后的陶瓷采用激光系统加工完成后，陶瓷表面的涂覆溶液清洗干净并将激光与材料作用产生的粉体以振动的方式脱离陶瓷表面，因涂覆溶液是亲水性，加工完成的陶瓷使用清水冲洗即可将表层的涂覆液去掉，易于去除，无毒无害，可达到食品级，环保性能高。
由涂覆载台固定所要用于加工的陶瓷基板，对其表面进行着色。涂覆载台可设计为带有吸附功能，防止在涂抹过程中基板晃动。涂抹完成后可静置1分钟左右，待基板自行晾干后方可拿走堆叠到一起，避免基板潮湿 时两片叠加引起露白。使用酒精作为溶剂，借助酒精易挥发的特性，涂抹完成后可直接将片子取出叠放。设计放置基板的治具，涂覆好的基板片与片之间都有间隔，促进基板干燥，防止基板划伤，以及陶瓷基板表面涂覆好均与的液体被污染。
采用1064nm近红外IPG-QCW光纤激光器，与普通的连续激光器相比，具有很高的峰值功率和比较长的脉宽，尤其是在和材料作用时通过瞬间高峰值功率热，较低占空比与材料发生高温烧蚀了去除物质，使用这种方式可以极大地减小热影响区域；可以获得很好的边缘效果；陶瓷背面挂渣比较松软。用于批量加工不同规格，不同型号的陶瓷样品，进而用于验证陶瓷表面被涂覆以后是否还存在漏光，跳线，加工不一致的问题。
采用超声起泡清洗池，主要作用是用于清洗待激光系统加工完成的陶瓷基板，去除表层的陶瓷涂覆液和表层因激光与材料接触产生的粉尘。
将超声清洗完成的陶瓷基板放进烘箱内进行短时间去除陶瓷表层的水分，干燥时间一般2-3分钟即可，干燥完成后快速打包封装。
本发明涂覆溶液应用于陶瓷激光加工，直接涂覆在陶瓷表面，促进红外激光对陶瓷吸收，近红外波段的吸收率高，避免出现断光、漏线等现象，加工效率高。涂覆溶液所采用的成分均为无毒，环保食品级的粉体，容易从市场上获取，制作简单，并且易溶于水。涂覆溶液制备时，采用磁力搅拌器具有一定的升温温控功能，内部有磁子以不同速度转动，能够起到加速涂覆溶剂粉体溶解，提供配比效率。激光加工系统加工陶瓷具有加工速度快、加工质量好的特点，还具备验收基板是否存在裂纹的情况。适合激光对陶瓷类(氧化铝、氧化锆、氮化铝)划线和切割使用，亦可作为其他材料加工时的保护剂使用，可广泛用于COB、LED照明、汽车电子等加工领域。
需要理解到的是：以上所述仅是本发明的优选实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若 干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
