Abstract

本发明涉及一种适用于低温的建筑用快干型胶水,特别涉及一种于低温(‑15℃)下仍可快速挤出操作使用且具有一定粘接力的胶水。其制作方法是先用溶剂将石油树脂及乙烯‑丁烯橡胶溶解后,再加入粉剂及己二醇搅拌,整个过程中温度控制在40℃以下。在低温下能否迅速将胶水挤压出来且仍具有一定粘接力,主要取决于溶剂配方的比例。本发明的溶剂是由:庚烷(Heptane)、丙酮(Acetone)、正己烷(N‑hexane)、甲苯(Toluene)依比例调整混合而成,其中,丙酮可增加橡胶对溶剂的溶解度,使胶体于低温(‑15℃)下,橡胶的溶解度不会因温度下降而降低,导致橡胶与溶剂产生分层或胶体结块无法使用等现象。

Description

适用于低温的建筑用快干型胶水及其制备方法和应用
技术领域
本发明涉及一种适用于低温的建筑用快干型胶水及其制备方法和应用,其是通过调整溶剂的配方比例,而得到的能于极低温(-15℃)时迅速挤出的建筑用快干型胶水。
背景技术
本发明所涉及的胶水,为建筑业常用的一种强力免钉胶,其黏度佳,无需使用钉子就可达到紧密黏合的效果,即使在面对恶劣低温(-15℃)的环境下,也必须可快速挤出操作使用,并仍具有一定粘接力。然而,因为气候变化,低温会导致稠状的胶水较难挤压出来,加上一般快干式的胶水为了使胶水能快点固化,以便工程能快速施作,该胶水较一般胶水更为浓稠,所以在低温时会更难挤压出来,使得施工时相当困扰且费力;而另有一种较好挤压的胶水,在低温(-15℃)环境中容易将其挤压出来,然而,此种胶水由于固化的速度较慢,因而影响工程施工的效率,所以胶水在低温(-15℃)的状态,存在许多使用上的缺失。
此外,胶水都具有挥发性,含有挥发性有机化合物VOC(VOLATILE OR-GANICCOMPOUNDS),而这也是非工业环境中最常见的空气污染物的源头之一,VOC的主要成分有:烃类、卤代烃、氧烃和氮烃,包括苯系物、有机氯化物、氟里昂系列、有机酮、胺、醇、醚、酯、酸和石油烃化合物等。一般常见的VOC有苯乙烯、丙二醇、甘烷、酚、甲苯、乙苯、二甲苯、甲醛等。在室外空间,VOC主要来自燃料燃烧和交通运输;而在室内则主要来自建筑和装饰材料、家具、家用电器、清洁剂和人体本身的排放等。在室内装饰过程中,VOC主要来自油漆、涂料和胶粘剂。由于VOC具有强挥发性,一般情况下,油漆施工后的10小时内,可挥发出90%,而溶剂中的VOC则在油漆风干过程中只释放总量的25%。该VOC的毒性会影响人体的健康,造成头痛、注意力不集中、厌倦、疲乏等问题,严重时,更导致过敏和癌症。为了防止VOC对人体的伤害,主要必须从原料开始把关,确实杜绝非环保建材,并在建筑完工后必须检测确认VOC不超标,并通风一个月后才能入住。
本发明发明人专门从事于研究黏胶技术的工作,为解决现有技术中快干型胶水在低温中(-15℃)使用的缺失,尽力思考解决之法,最终凭借自身的专业及多年来的工作经验,再配合反复的试验、修正与改进后,研究出本发明适用于低温的建筑用快干型胶水。
发明内容
本发明涉及一种适用于低温的建筑用快干型胶水,特别涉及一种于低温(-15℃)下仍可快速挤出的快干型胶水,且该胶水仍具有一定的粘接力。
本发明的胶水的溶剂由下列成分组成:庚烷(Heptane)、丙酮(Acetone)、正己烷(N-hexane)及甲苯(Toluene)。
除溶剂外,胶水中还添加有添加成分:碳九石油树脂(Petroleum resin SK 120)、碳五石油树脂(LUHOREZ A-1100)、乙烯-丁烯橡胶(Taipol 3206)、锻烧高岭土(KAOLINBR95)、碳酸钙(CaCO3ES 500)、抗氧化剂(Evernox 10)、二氧化硅(AEROSIL 200)及乙二醇(Monoethyelene glycol)
优选的,胶水中各成分的重量百分比为:庚烷2.0-5.0%、丙酮10-20%、正己烷10-20%、甲苯1.0-5.0%、碳九石油树脂15-25%、碳五石油树脂1-5%、乙烯-丁烯橡胶10-20%、锻烧高岭土20-35%、碳酸钙10-20%、抗氧化剂2-6%、二氧化硅0.5-1%及乙二醇0.1-0.5%。
本发明的胶水的制作方法为,
(1)将配方量的庚烷、丙酮、正己烷、甲苯预先调配成溶剂;
(2)向溶剂中加入配方量的碳九石油树脂、碳五石油树脂及乙烯-丁烯橡胶进行溶解;
(3)将配方量的锻烧高岭土、碳酸钙、抗氧化剂、二氧化硅及乙二醇陆续添加到步骤(2)得到的溶解后的树脂与橡胶中,并利用三轴搅拌机进行搅拌,得到黏稠状的胶水(也可称为“免钉胶”)。
优选的,全程温度均控制在40℃以下。
本发明的胶水之所以能在极低的温度中,可被迅速挤压出来,其关键主要在于溶剂配方的比例。本发明的溶剂是由:庚烷(Heptane)2.0-5.0%、丙酮(Acetone)10-20%、正己烷(N-hexane)10-20%、甲苯(Toluene)1.0-5.0%依比例调整混合而成,其中,丙酮可增加橡胶对溶剂的溶解度,使胶水于低温(-15℃)下,橡胶的溶解度不会因温度下降而降低,导致橡胶与溶剂产生分层或胶体结块无法使用等现象。本发明的免钉胶完全突破现有胶水在低温下较难挤压的缺失,是一种又好挤压又快干的胶水,能有效提升低温环境中的施工效率。

具体实施方法
下面结合具体实施例来进一步描述本发明,本发明的优点和特点将会随着描述而更为清楚。但这些实施例仅是范例性的,并不对本发明的范围构成任何限制。本领域技术人员应该理解的是,在不偏离本发明的精神和范围下可以对本发明技术方案的细节和形式进行修改或替换,但这些修改和替换均落入本发明的保护范围内。
请参阅图1,图1为本发明适用于低温的建筑用快干型胶水的制作流程图,本实施例的制作步骤如下:
(1)按重量百分比计,将庚烷11(Heptane)2.0-5.0%、丙酮12(Acetone)10-20%、正己烷13(N-hexane)10-20%、甲苯14(Toluene)1.0-5.0%预先调配成溶剂1;
(2)向溶剂1中加入碳九石油树脂21(Petroleum resin SK 120)15-25%、碳五石油树脂22(LUHOREZ A-1100)1-5%及乙烯-丁烯橡胶23(Taipol 3206)10-20%进行溶解;
(3)将锻烧高岭土31(KAOLIN BR95)20-35%、碳酸钙32(CaCO3ES 500)10-20%、抗氧化剂33(Evernox 10)2-6%、二氧化硅34(AEROSIL 200)0.5-1%、乙二醇35(Monoethyelene glycol)0.1-0.5%陆续添加到步骤(2)得到的溶解后的树脂与橡胶20中,并利用三轴搅拌机进行搅拌,得到黏稠状的免钉胶2;
其中,全程温度均控制在40℃以下。
利用本发明的制作方法所制成的胶水,在低温(-15℃)状态下仍然能顺利快速的挤出胶水,并具有良好的粘接效果,突破传统胶水在低温下无法顺利挤出的缺失。为了进一步证明本发明确实能达到快速挤出的目的,发明人对所制胶水的挤出率进行了测试。
测试指标为用气动式软包专用胶枪在固定的压力(20PSI),固定的管嘴口径(3.0mm)下挤出20g胶水所需的时间。一般来说在低温(-15℃)状态下,传统的胶水是无法挤出的,本发明的胶水(168)在-15℃时挤出的时间仅比在室温时略长,比传统无法挤出的胶水更为进步、实用,具体挤出率测试结果如下表所示:
综上所述,本发明完全突破现有胶水在低温下较难挤压的缺失,提供了一种又好挤压又快干的胶水,有效提升了低温环境中的施工效率。因未见有相关刊物发表,符合申请发明专利要件,因此依法提出专利申请。
