(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

根據前文分析，自密封安全輪胎聚氨酯密封膠可歸類為壓敏膠。而增粘樹脂是壓敏膠的組成部分之一，聚氨酯密封膠膠料中所用樹脂的種類、用量都會對聚氨酯密封膠膠料的性能產生明顯影響。
在熱熔型壓敏膠的各種研究中，前人己經對各類增粘樹脂對熱熔型自修復密封膠性能的影響進行過研究。本節則會研究碳九、碳五樹脂、松香、菇烯對本文制備的丁基橡膠與聚異丁烯為基體的微交聯型自修復氣密膠性能的影響。
增粘樹脂是一類中小分子量的樹脂，分子量通常不超過一萬，一般用于壓敏膠的增粘劑以提高表面粘性或用于橡膠制品增加表面粘性和降低加工過程中混煉膠的粘度。本節主要討論增粘樹脂對本文所制備聚氨酯密封膠膠料性能的影響。不同增粘樹脂對聚氨酯密封膠膠料T型剝離強度的增強作用對比。
本節采用了碳五樹脂、碳九樹脂、菇烯樹脂、松香樹脂四種樹脂進行了聚氨酯密封膠膠料增粘改性，按照表2-8設置加入增粘樹脂的種類為變量，每種樹脂添加3.75份，測試其T型剝離強度，以此分析四種增粘樹脂的效果。下圖4-41、表4-7為分別添加四種不同增粘樹脂后聚氨酯密封膠膠料與玻璃紙之間剝離強度的測試結果。www.kubee.cn
