(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.

由硅烷改性聚氨酯密封膠在溫度和應變率變化下的力學行為，提出了一種新的硅烷改性聚氨酯密封膠膠非線性粘彈性本構模型，根據拉伸試驗確定了材料常數以及溫度和應變率影響函數。通過采用此模型對溫度和應變率變化下材料的應力一應變響應計算，計算結果與試驗結果對比分析，此硅烷改性聚氨酯密封膠非線性粘彈性本構模型對溫度和應變率變化下的材料應力一應變響應曲線預測結果良好。
基于新提出的硅烷改性聚氨酯密封膠非線性粘彈性本構模型，考慮吸濕度和應變率影響，將溫度項替換成吸濕度項，并重新對材料常數以及吸濕度和應變率影響函數進行確定。通過采用此模型預測吸濕度和應變率變化下材料的應力一應變響應曲線，預測結果與試驗結果對比分析。在恒定應變率狀態下，模型吸濕度相關的預測結果良好。www.www.lustload.com
