单组分有机硅密封胶在汽车车灯领域的研究进展

Research progress of one-component silicone sealant in the field of automobile lights

汽车车灯作为汽车必不可少的一个组件,制作中为了将配光镜与灯壳进行密封,必须使用密封胶进行黏接。为解决密封胶密封性能受使用环境恶劣影响等问题,对车灯用密封胶的使用现状以及国内外研究进展情况进行了综述,确定了单组分有机硅密封胶是汽车车灯领域密封胶的研究重点,并分析了该密封胶面临的技术问题和改进措施,提出了湿气固化型单组分室温硫化有机硅密封胶是今后的研发方向和研究重点。

As an indispensable component of the car,the car lamp must be bonded with a sealant in order to seal the light distribution mirror and the lamp housing.In order to solve the problem that the sealing performance of the sealant is affected by the harsh environment,the current situation and the research progress of the automobile lamps sealant at home and abroad are reviewed,and it is determined that the one-component silicone sealant is the best sealant in the field of automobile lamps.The research focus is analyzed,the technical problems and improvement measures are analyzed.It is proposed that the moisture-curable one-component room temperature vulcanized silicone sealant is the future research and development direction and research focus.
