Description

一种实木颗粒板异佛尔酮二异氰酸酯防火涂料及制备方法
技术领域
本发明涉及一种防火涂料，具体说是一种实木颗粒板异佛尔酮二异氰酸酯防火涂料及制备方法。
背景技术
实木颗粒板，是由木材或其他木质纤维素材料制成的碎料，施加胶粘剂后在热力和压力作用下胶合成的人造板。原理和密度板是一样的。 实木颗粒板作为一种新型、高档环保的基材被欧美国家家具生产商所广泛采用，国内高档板式家具市场也开始大面积采用该种板材。由于其内胶与颗粒之间仍存在间隙，在长时间高温环境下极易引燃，因此现有的防火涂料无法满足其长时间高温环境下的防火要求。
发明内容
针对现有技术中的上述不足，本发明提供了一种能满足长时间高温环境下防火要求的，适用于实木颗粒板防火要求的异佛尔酮二异氰酸酯防火涂料及制备方法。
本发明采用的技术方案是：一种实木颗粒板异佛尔酮二异氰酸酯防火涂料，按质量比组成包括：异佛尔酮二异氰酸酯80-90份、苯甲酸25-30份、邻苯二甲酸30-35份、碘化铵20-30份、石棉粉20-25份、环氧树脂4.5-9份、钛白粉5.0-10份、沉淀硫酸钡2-5份、阻燃剂1-2份、三氧化二锑1-1.5份、有机膨胀土2-3份。
一种实木颗粒板异佛尔酮二异氰酸酯防火涂料制备方法，先将异佛尔酮二异氰酸酯80-90份、苯甲酸25-30份、邻苯二甲酸30-35份加入反应釜中加热150-180℃反应24-36小时；再加入碘化铵20-30份、石棉粉20-25份、环氧树脂4.5-9份、钛白粉5.0-10份、沉淀硫酸钡2-5份、阻燃剂1-2份、三氧化二锑1-1.5份、有机膨胀土2-3份搅拌均匀，在70-80℃反应5-8小时即得涂料。
本发明的涂料制作方便、成本低，且应用于间隙板材类的实木颗粒板上时，能在长时间、较高温度下阻止内部燃烧，起到较好的防火性能。
