(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(yīng)變率變化下的力學(xué)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(gòu)模型，根據(jù)拉伸試驗(yàn)確定了材料常數(shù)以及溫度和應(yīng)變率影響函數(shù)。通過采用此模型對(duì)溫度和應(yīng)變率變化下材料的應(yīng)力一應(yīng)變響應(yīng)計(jì)算，計(jì)算結(jié)果與試驗(yàn)結(jié)果對(duì)比分析，此硅烷改性聚氨酯密封膠非線性粘彈性本構(gòu)模型對(duì)溫度和應(yīng)變率變化下的材料應(yīng)力一應(yīng)變響應(yīng)曲線預(yù)測(cè)結(jié)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(gòu)模型，考慮吸濕度和應(yīng)變率影響，將溫度項(xiàng)替換成吸濕度項(xiàng)，并重新對(duì)材料常數(shù)以及吸濕度和應(yīng)變率影響函數(shù)進(jìn)行確定。通過采用此模型預(yù)測(cè)吸濕度和應(yīng)變率變化下材料的應(yīng)力一應(yīng)變響應(yīng)曲線，預(yù)測(cè)結(jié)果與試驗(yàn)結(jié)果對(duì)比分析。在恒定應(yīng)變率狀態(tài)下，模型吸濕度相關(guān)的預(yù)測(cè)結(jié)果良好。www.kubee.cn
