(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.

聚氨酯密封胶与镀锌板的粘接强度直接影响复合材料的性能，因此研究讨论聚氨酯密封胶与镀锌板粘接强度的影响因素对于提高粘接质量具有重要意义。讨论了多元醇种类、多元醇轻基值、rt值、填料含量、附着力促进剂用量和镀锌板的表面处理方法对聚氨酯密封胶与镀锌板粘接强度的影响。结果表明，含环氧基的多元醇、高轻基值多元醇、rt值为i.s, 60%填料含量、3%附着力促进剂用量和镀锌板表面打磨和抛丸的处理方法可以增强聚氨酯密封胶与镀锌板粘接强度。

聚氨酯是一种发展迅速的多功能高分子合成材料，由于原料品种的多样化以及分子结构的可调节性，可制成泡沫塑料、弹性体、聚氨酯密封胶、涂料等多种产品形式，用途极其广泛。同样，通过调节其原料及配方，可设计出适合各种材料间的粘接、各种不同用途的多种类型聚氨酯密封胶。聚氨酯胶层具有优良的柔韧性、耐冲击性、耐化学药品性，并且具有特别优异的耐低温性能及耐磨性。聚氨酯密封胶是一种高中档聚氨酯密封胶川。

镀锌板是指表面镀有一层锌的钢板。镀锌是一种经常采用的经济而有效的防锈方法，世界上锌产量的一半左右均用于此种工艺。镀锌钢板是为防止钢板表面遭受腐蚀延长其使用寿命，在钢板表面涂以一层金属锌，这种涂锌的钢板称为镀锌板。镀锌层具有良好的耐腐蚀性能，一方面是由于镀层作为阻挡层，隔离了基体与周围的腐蚀环境;另一方面，镀锌层可作为牺牲阳极，对机体产生电化学防护作用川，所以，镀锌板能抗锈蚀主要是因为覆盖在钢板表面的锌层可以在腐蚀环境中形成耐蚀层，使钢板本身免受腐蚀，延长其使用寿命。

镀锌板带钢产品主要应用于建筑、轻工、汽车、农牧渔业及商业等行业。其中建筑行业主要用于制造防腐蚀的工业及民用建筑屋面板、屋顶格栅等;轻工行业用其制造家电外壳、民用烟囱、厨房用具等，汽车行业主要用于制造轿车的耐腐蚀部件等;农牧渔业主要用做粮食储运、肉类及水产品的冷冻加工用具等;商业主要用作为物资的储运、包装用具等。

镀锌板应用领域广泛，但是钢板经过表面镀锌后，表面具有较强惰性，导致不好粘接，因此，本文探讨了聚氨酯密封胶与镀锌板粘接强度的影响因素。www.sdyuantai.com
