3. Application                                                                                                      

At present countries over the world get interest in 3.5 Water Zinc Borate, and is widely used to manufacture plastic, PVC, PE, PP, EVA, ABS, epoxide resin, unsaturation resin, phenolic resin, urethane foam. It is also used in rubber Industry such as neoprene, polybutadiene rubber, Buna-N rubber and paper, textile. In special plastic industry, it can replace diantimony trioxide and effectively prevent from smoke. It also can take the place of zinc chromate as primer, ceramics glaze, pesticide.

简介:

硼酸锌是一种环保型的非卤素阻燃剂,根据组成不同(XZnO.YB2O3.ZH2O),FB阻燃剂有十几个品种。最常用的品种为本品-3.5水硼酸锌, 又称ZB-2335阻燃剂。本产品无毒、低水溶性、高热稳定性、粒度小、比重小、分散性好等特点,作为一种高效阻燃剂被广泛应用在塑料、橡胶、涂料等领域。


产品应用:

1. 硼酸锌可以作为氧化锑或其它卤素阻燃剂的多功能增效添加剂,可以有效提高阻燃性能,减少燃烧时烟雾的产生,并可以调节橡塑产品的化学,机械,电等方面的性能。 
2. 作为含卤素等阻燃剂的部分或完全环保替代品,硼酸锌正在被广泛的直接应用于塑料和橡胶的加工,如PVC、PE、PP、增强聚酰胺、聚氯脂、聚苯乙烯、环氧树脂、聚脂酸乙烯树脂及天然橡胶,苯乙烯丁二烯橡胶、氯丁橡胶等。还可以被应用于纸张、纤维织物、装饰板、地板革、壁纸、地毯、陶瓷釉料、杀菌剂,涂料的生产中,以提高阻燃性能。 
3. 基于硼酸锌的其它性质,还可用于防腐,远红外线吸收,木材的防虫防菌处理等领域。
