(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.

为提升羽毛球拍专用硅烷改性聚氨酯密封胶的抗菌性能，提出了一种融合c,8-QAs抗菌剂的抗菌功能性硅烷改性聚氨酯密封胶材料。在聚硅氧烷基材的基拙上导入c,8-QAs抗菌剂，再通过硫化处理的方式制备出抗菌功能性硅烷改性聚氨酯密封胶。为验证抗菌功能性硅烷改性聚氨酯密封胶的综合性能，运用邵氏硬度计、拉力材料试验仪以及测角仪等设备对该材料的力学性能和亲疏水性能进行测试，通过乙酞接触法和甲苯平衡溶胀法对该材料的表干性能和交联密度进行测试，并根据测试结果来确定c,8-QAs抗菌剂的合理掺量。经试验研究发现，当Cl8-QAS抗菌剂掺量为3%时，抗菌性硅烷改性聚氨酯密封胶的综合性能最为理想，可满足羽毛球拍在粘接密封工艺阶段的使用需求。

硅烷改性聚氨酯密封胶具有高耐候性、高稳定性、高耐热性等方面的特征，是羽毛球拍生产加工所需的重要高端材料。然而，该材料在高温、潮湿环境下容易受到霉菌污染，会对羽毛球拍的使用寿命和力学性能造成一定影响。随着我国体育器材消费市场的不断发展，高端羽毛球拍的市场需求日益扩大，加强抗菌型密封胶合成材料的技术研究对于提升羽毛球拍综合性能有重要意义。因此，研究在硅烷改性聚氨酯密封胶中添加二甲基十八烷基3-(三甲氧基硅基)丙基」氯化钱(C,8-QAS)抗菌剂，制备出一种具有抗菌效果的季钱盐类硅烷改性聚氨酯密封胶(QAS/PDMS),并对该密封胶的综合性能进行检测从表干性能、交联密度、力学性能、亲疏水性能等方面的角度对该材料在羽毛球拍生产加工应用方面的合理性加以验证。http://www.sdyuantai.com/
