内容简介:
聚氨酯泡沫是以异氰酸酯和聚氨酯硬泡为主要原料,在发泡剂、催化剂、阻燃剂等多种助剂的作用下,通过专用设备混合,经高压喷涂现场发泡而成的高分子聚合物。聚氨酯泡沫有软泡和硬泡两种。软泡为开孔结构,硬泡为闭孔结构;软泡又分为结皮和不结皮两种。
聚氨酯硬泡是指在一定负荷作用下不发生明显形变,当负荷过大发生形变后不能恢复到初始状态的泡沫塑料,具有优良的物理机械性能、声学性能、电学性能和耐化学性能,尤其热导率极低,是-种性能优良的绝热材料和结构材料。聚氨酯硬泡主要用于冷藏保温及建筑节能行业。
聚氨酯硬泡并非标准化产品,硬泡组合聚氨酯硬泡行业壁垒较高。不同的起始剂、不同的PO接挂数量可以得到不同牌号的单体聚氨酯硬泡,其羟值、粘度、外观、含水量和应用领域均不相同。组合聚氨酯硬泡是典型的“配方型”产品,配方中各个原材料的添加量和比例均有调整空间。由于异氰酸酯是同质的,聚氨酯的最终性能基本全由组合聚氨酯硬泡决定。
2021年中国家电冷藏行业耗用硬泡组合聚醚56多万吨,是硬泡组合聚醚的主要应用领域,也是最高端的应用市场。而在发达国家,硬泡组合聚醚的主要消费领域是建筑外保温领域;在中国,冰箱(柜)冷藏集装箱冷藏行业一直是硬泡组合聚醚最大的消费领域,占比接近50%。
2017年中国聚氨酯硬泡消费量176.0万吨,同比增长8.6%;2018年中国聚氨酯硬泡消费量180.0万吨,同比增长2.3%;2019年中国聚氨酯硬泡消费量183.0万吨,同比增长1.7%;2020年中国聚氨酯硬泡消费量206.0万吨,同比增长12.6%;2021年中国聚氨酯硬泡消费量247.0万吨,同比增长19.9%。其中硬泡组合聚醚万吨、聚合MDI133.7万吨。
