Definitions
- the present disclosure relates to the field of materials, in particular to an adhesive and its preparation method and application.
- many adhesives with unique uses have been successfully developed, including underwater adhesives, water-based adhesives, low-temperature resistant adhesives, etc.
- glue it is necessary to use glue to firmly adhere the processed object to the bracket during processing. After that, the workpiece needs to be disengaged from the bracket under certain external stimuli.
- methods such as immersion in organic solvents, heating, and UV irradiation are usually required to separate adhesives and adhesives, but this is not only energy-intensive and time-consuming, but also causes environmental problems. Not only that, heat-sensitive workpieces are often prone to surface damage and corrosion during the separation process.
- Ionic gel adhesives based on polymers and ionic liquids may be a potential solution to this problem.

Description
相关申请的交叉引用
本公开要求于2021年10月29日提交中国专利局的申请号为CN202111268968.9、名称为“胶粘剂及其制备方法和用途”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
本公开涉及材料领域,尤其涉及一种胶粘剂及其制备方法和用途。
胶粘剂在日常生活中起着重要的作用,如医疗、电子、房屋建筑和汽车。在过去的十年中,有很多具有独特用途的胶粘剂被成功开发了出来,包括水下胶粘剂、水基胶粘剂、耐低温胶粘剂等。然而在其他特殊领域,如在钻孔、切片光学透镜过程中,加工时需要用胶水将被加工物体牢固地粘在支架上。之后,工件需要在一定的外界刺激作用下与支架脱开。传统上,通常需要使用诸如有机溶剂浸泡、加热和UV照射等方法来分离粘合剂和粘合剂,但这不仅耗能又耗时,而且还会导致环境问题。不仅如此,热敏性工件在往往容易在分离过程发生表面破坏和腐蚀。
基于聚合物和离子液体(ILs)组成的离子凝胶胶粘剂可能是解决这一难题的潜在方法,离子凝胶胶粘剂的强粘结性能得益于聚合物链官能团与离子液体间丰富的相互作用,这种弱的相互作用可以在拉伸胶粘剂时通过耗散机械力来保持胶粘剂的完整性。然而,在触发剥离方面,离子凝胶粘接的试件往往需要通过上述触发才能使工件剥离。不仅如此,离子凝胶昂贵的价格和毒性也阻碍了离子凝胶胶粘剂的进一步商业化。

对比例1
使用商用3M快干胶(型号CA40H)粘结不同的基材(玻璃,金属,陶瓷,塑料),以在下文中测量其与本公开不同基材的搭接剪切强度。
实验例1胶黏剂的性能测试
测试上述实施例1-11和对比例1得到的胶粘剂的胶粘性能和水浸泡脱胶时间,测试方法如下:
(1)胶粘性能测试:
选择玻璃基材(基材不限于玻璃基材,也可以为金属、陶瓷等基材,本公开测试方法以玻璃基材为例),在测试之前使用肥皂水、乙醇和丙酮依次彻底清洗基材表面。将基材放置隔夜以挥发表面残留溶剂。将来自实施例1-11和对比例1得到的胶粘剂在两个玻璃基材之间进行紫外固化,得到测试样条。随后针对已制备的测试样条进行搭接剪切实验,每个实施例或对比例的样品进行三次平行测试。该实验基于ASTMD1002测试方法,采用深圳三思UTM 6104拉力机,在室温条件下进行胶粘性能测试。拉力机以2mm/min的速率拉伸测试样条直至失效,同时记录最大剪切力和两块基材的重叠区域面积。
(2)水浸泡脱胶时间测试:
将上述所制备的测试样条在室温(25℃)的条件下直接置于去离子水中进行浸泡,并按照不同浸泡时间将上述测试样条分为7组,分别将测试样条浸泡2min、4min、6min、8min、10min、12min和14min,随后取出测试样条,使用吹风机快速除掉表面残存的水分,随后立即用深圳三思UTM6104拉力机根据上述测试条件获得搭接剪切强度。将搭接剪切强度为0MPa 时的时间定义为水浸泡脱胶时间,每组中对应每个测试样进行三次平行测试。
测试结果如下表1所示:
表1测试结果
样品 | 粘接强度(MPa) | 水浸泡脱胶时间(min) |
实施例1 | 12.5±1.23 | 10 |
实施例2 | 6.56±1.63 | 10 |
实施例3 | 8.3±1.87 | 10 |
实施例4 | 9.91±1.32 | 10 |
实施例5 | 10.14±0.52 | 10 |
实施例6 | 7.91±1.24 | 10 |
实施例7 | 12.78±2.73 | 10 |
实施例8 | 4.66±0.75 | 10 |
实施例9 | 4.79±1.00 | 10 |
实施例10 | 9.73±2.86 | 10 |
实施例11 | 6.44±1.02 | 10 |
对比例1 | 2.00±0.40 | / |
由上表1可知,以粘接基材都为玻璃举例,对比例1提供的商用的3M快干胶在玻璃上的粘接性能只有2MPa,只有本公开制备的胶粘剂的20%不到,与对比例相比,由本公开制备的胶粘剂的粘接强度显著提高。
本公开制备的胶粘剂可以在水的浸泡下迅速脱粘:将本公开提供的胶粘剂浸入水中十分钟后,粘接强度立即有了大于80%的下降,便于光学镜片加工后的脱粘。
本公开提供的胶粘剂可完全溶于水中,成本较低且对环境友好。
最后应说明的是:以上各实施例仅用以说明本公开的技术方案,而非对其限制;尽管参照前述各实施例对本公开进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进 行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本公开各实施例技术方案的范围。
此外,本领域的技术人员能够理解,尽管在此的一些实施例包括其它实施例中所包括的某些特征而不是其它特征,但是不同实施例的特征的组合意味着处于本公开的范围之内并且形成不同的实施例。例如,在上面的权利要求书中,所要求保护的实施例的任意之一都可以以任意的组合方式来使用。公开于该背景技术部分的信息仅仅旨在加深对本公开的总体背景技术的理解,而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。
本公开提供一种胶粘剂及其制备方法和用途,本公开的胶粘剂具有高粘接强度且触发脱开的优势,同时能很好地被水溶解致使胶粘剂与被粘基材脱开,在提升性能的同时也降低了原材料的成本和安全性,因此具有优异的应用性能,应用领域广泛,尤其可以用于光学产品的生产。
