建筑外部材料技术交流活动 - 建筑外墙胶类
On the afternoon of June 13th, Rinro (Rinro Facade Consultant) invited Zhengzhou Zhongyuan Thinkland High-tech Co., Ltd. to our company to carry out technical exchange activities for building exterior wall sealant.
6月13号下午,Rinro(凝龙幕墙咨询)邀请郑州中原思蓝德高科股份有限公司到我司进行了建筑外墙胶类的技术交流活动。



There are many materials in the building's exterior walls, and the performance is different. New technologies and new products emerge one after another. As a consulting company for building exterior wall design, every employee must keep up with the pace of product development and constantly update the knowledge base so as to serve the customer more professionally. .

建筑外墙材料繁多,性能不一,新技术新产品层出不穷,作为建筑外墙设计咨询企业,每一位从业人员都必须紧跟产品发展的步伐,不断更新知识库,从而更专业地服务于客户。



In about two hours of communication time, Yang made a systematic introduction to the glue used in the construction of exterior walls and summarized the typical failure cases and solutions of sealant in modern buildings.
In particular, the 25-year warranty on silicone structural sealants has been highlighted.
By comparing the advantages and disadvantages of American Standard ASTM C1184, National Standard GB16776, and European Standard ETAG002, she emphasized the importance and feasibility of promoting the 25-year warranty on silicone structural sealants in China. Special mention was made of the addition of thermo gravimetric analysis to new standards. Infrared spectroscopy tests, requirements for shear adhesion, tear strength, mechanical fatigue testing, creep, and environmental impact.
It is worth noting that the 25-year warranty product will increase the cost of about 30 to 50% on the basis of the original 10-year warranty. However, taking into account the fact that developed countries generally adopt the 25-year warranty, and that plastics account for approximately 1% to 2% of the total material cost, the selection of more assured products is worth adopting and promoting. Considering in particular that the Ministry of Housing and Urban-Rural Development and the State Administration of Safety Supervision have further strengthened the safety protection work for glass curtain walls, Jianbao [2015] No. 38 has imposed stringent requirements on hidden frames. The new requirement for this national standard should be timely. Progressive.
在约两个小时的交流时间里,杨总对建筑外墙用胶做了系统的介绍,总结了密封胶在现代建筑中的典型失效案例及解决方案。
特别是对硅酮结构密封胶的25年质保做了重点的说明。
她通过对比美标ASTM C1184,国标GB16776,欧标ETAG002的优劣点,强调了中国推进硅酮结构密封胶25年质保的重要性与可实施性,特别提及新标准增加了热重分析,红外光谱分析测试,对剪切粘结性,撕裂强度,机械疲劳试验,蠕变及对环境影响的要求。
值得说明的是,25年质保产品会在原10年质保基础上增加约30~50%的成本。但考虑发达国家普遍采用25年质保的实际情况下,以及胶类约占总材料成本1%~2%的基础上,选择更有保证的产品,是值得采用及推广的。特别考虑到住房城乡建设部与国家安全监管总局关于进一步加强玻璃幕墙安全防护工作的通知建标[2015]38号对隐框做严格要求的背景下,这一国家标准的新要求应该是与时俱进的。



In addition, at the exchange meeting, we had a lively discussion on the tearing (oil) phenomenon of insulating glass, leakage of hollow glass, leakage of water, cracking phenomenon of sealant, stone pollution, and high-strength structural adhesives.
此外,交流会上,大家对中空玻璃的流泪(油)现象,中空玻璃漏气、漏水,密封胶开裂现象、石材污染现象等质量事故及高强度结构胶做了热烈的讨论。
Everyone was particularly interested in the bathroom and the moldy phenomenon of the kitchen sink sealant. The main reason is that due to the results of acidic sealants used in most cases, it is actually recommended to use neutral sealants or “mildew proof” sealant products in order to avoid such commonplace quality problems.
大家特别对家庭的卫生间,厨房水槽密封胶发霉现象很感兴趣。主要原因是由于在大部分案例中大家使用了酸性密封胶的结果,实际上应该推荐使用中性密封胶或者“防霉“性能的密封胶产品,以避免出现此类司空见惯的质量问题。



The phenomenon of cracking on the market sealant and the phenomenon of hollow glass flow are mainly due to the fact that the bad manufacturers reduce the cost of the sealant and fill the sealant with low-boiling substances such as white oil, which leads to gradual volatilization of the low-boiling substances, resulting in the change of the sealant. Hard, brittle and appear cracking phenomenon; In addition, white oil can dissolve butyl sealant, which will also affect the performance of hollow glass.
关于市面密封胶出现开裂现象及中空玻璃流淌现象,主要原因是由于不良厂家为降低密封胶的成本,在密封胶中填充白油等低沸点物质,这导致低沸点物质逐渐挥发,致使密封胶变硬、变脆而出现开裂现象;此外,白油能够溶解丁基密封胶,这也会影响到中空玻璃的使用性能。



As a curtain wall design and consulting company that pursues the quality of exterior walls, Rinro (Ninglong Facade Consulting) continues to maintain long-term and in-depth exchange activities with leading material brands in the construction field, promoting the building's exterior wall industry to advance together to solve the problem of owners and Difficulties encountered by the Design Institute.
