Definitions

  • the invention relates to the technical field of polymer materials, and more particularly, to a hot melt adhesive for insulating glass spacers and a preparation method thereof.
  • Insulating glass also known as insulating glass, is a special glass with a dry gas space formed between two or more sheets of flat glass, separated by a certain distance from each other, and the periphery is sealed to form a dry gas space between the glasses.
  • Insulating glass has the characteristics of heat insulation, heat preservation, sound insulation, and anti-condensation, and has a wide range of applications in architectural decoration, energy-saving vehicles and refrigeration equipment.
  • Butyl hot melt adhesive is basically used as the first seal in the double-sealing system of insulating glass.
  • the performance of the glue plays a crucial role in the quality and life of the insulating glass.
  • Butyl hot melt adhesive is a one-component, solvent-free, non-fogging, non-vulcanizing, permanent plastic first sealant for insulating glass based on polyisobutylene rubber.
  • Hot-melt butyl sealant maintains its plasticity and sealing properties in a wide temperature range, and the surface does not crack or harden; it has good adhesion to glass, aluminum alloy, galvanized steel, stainless steel and other materials; due to With its extremely low water vapour transmission rate, it can form an excellent anti-moisture system with elastomeric sealants.
  • butyl hot melt adhesives for insulating glass systems are all non-reactive hot melt adhesives, which do not react with silicone, and the interface bonding effect is weak, which cannot play a good role in fixing and bonding.
  • low-cost mineral oil is often added as a plasticizer to the silicone adhesives on the market. Mineral oil is non-polar and easily migrates into the butyl hot-melt adhesive, softening or even dissolving the butyl rubber. It flows to the inner surface of the insulating glass, affecting the waterproofness and appearance of the insulating glass.

Description

一种用于中空玻璃间隔条的热熔胶及其制备方法
本申请要求于2021年1月18日提交中国专利局、申请号为202110063913.8、发明名称为“一种用于中空玻璃间隔条的热熔胶及其制备方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及高分子材料技术领域，更具体地说，是涉及一种用于中空玻璃间隔条的热熔胶及其制备方法。
背景技术
中空玻璃又称为隔热玻璃，它是由两片或两片以上的平板玻璃，彼此间隔一定距离，周边经过密封使玻璃之间形成具有干燥气体空间的一种特殊玻璃。中空玻璃具有隔热、保温、隔音、防结露等特点，在建筑装饰、节能车辆及制冷设备方面都具有广泛的应用。
为了保证建筑符合国家节能设计和使用要求，目前国内最成熟的方法是采用双道密封中空玻璃，丁基热熔胶在中空玻璃双道密封系统中基本用作第一道密封，丁基热熔胶的性能对中空玻璃的质量和寿命起着至关重要的作用。
丁基热熔胶是一种以聚异丁烯橡胶为基料的单组份、无溶剂、不出雾、不硫化、具有永久塑性的中空玻璃第一道密封剂。热熔丁基密封胶在较宽温度范围内保持其塑性和密封性，且表面不开裂、不变硬；它对玻璃、铝合金、镀锌钢、不锈钢等材料有良好的粘合性；由于其极低的水汽透过率，它可以与弹性密封剂一起构成一个优异的抗湿气系统。
然而目前中空玻璃系统用丁基热熔胶都为非反应型热熔胶，与硅酮不发生反应，界面粘接作用较弱，不能起到良好的固定粘接作用。另一方面，目前市场上的硅酮胶往往添加低价的矿物油作为增塑剂，矿物油由于为非极性，极易迁移到丁基热熔胶内，使丁基胶软化甚至溶解而流淌至中空玻璃内表面，影响中空玻璃的防水性和外观性。如公开号为CN102911625A的中国专利公开了一种热塑性间隔条及其制备方法，该热塑性间隔条与玻璃之间的化学粘结性好；但是，由于丁基橡胶和聚烯烃的分子量低对矿物油的耐受性差，极易被白油软 化，从而流淌；另一方面，粘接促进剂为小分子硅烷，因而不能有效提高丁基胶与硅酮胶的粘接性。
