Abstract
本发明公开了一种高强度硅系纤维板,包括以下重量份原料:10‑40份的无机复合纤维、40‑70份的耐火填料、10‑30份的无机结合剂、2‑10份的絮凝剂以及2000‑5000份的水;所述无机复合纤维包括多晶莫来石纤维和石英纤维;所述耐火填料由滑石粉、苏州土、工业Al2O3构成。本发明中的耐火填料在纤维板烧结的过程中会生成在堇青石粉,本发明中烧结出的堇青石粉填充于纤维交织的空隙之中作为耐火填料的主体,使得陶瓷纤维板具有极低的热膨胀系数和优良的耐高温性,并为纤维板提供刚性支撑,高温下能很好的保护纤维且极大增强了纤维板的抗热震性能。
Description
技术领域
本发明属于耐火材料制备技术领域,具体涉及一种高强度硅系纤维板及其制备方法。
背景技术
陶瓷纤维板是一种耐火材料,是有一定刚性并起支撑强度的纤维隔热产品,该材料具有导热率低、抗热震性能好等优点。目前,在窑炉的背衬保温,熔融金属转运包中等产品中得到了广泛的应用。
目前传统工艺生产的陶瓷纤维板的体积密度一般在200~500kg/m3,耐压强度≤1MPa,在应用方面具有很大的局限性。如在冶金钢包、中间包中,就需要既承重又保温的陶瓷纤维板,在使用过程中能够承受金属液体产生漩涡引起的局部压力过大和超温状态。现有技术的高密度板材需要在制备过程中预先对纤维进行短切处理,以使制备得到的纤维板满足密度和强度要求。但这一过程操作复杂,费时费力且制备的纤维板材往往采用真空吸附的方式,造成密度不均匀,且抗热震较差。传统陶瓷纤维板耐温度一般在1100℃以内,长期高温下使用由于纤维析晶等原因容易脆化、掉粉。
发明内容
为解决上述问题,本发明将采用以下技术方案:
本发明的一种高强度硅系纤维板,其特征在于,包括以下重量份原料:10-40份的无机复合纤维、40-70份的耐火填料、10-30份的无机结合剂、2-10份的絮凝剂以及2000-5000份的水;所述无机复合纤维包括多晶莫来石纤维和石英纤维;所述耐火填料包括滑石粉、苏州土、以及工业级Al2O3。
进一步地,所述无机复合纤维中所述多晶莫来石纤维和所述石英纤维的重量份数比为1:1到5:1。
进一步地,所述多晶莫来石纤维平均直径为3-5μm;所述多晶莫来石纤维中包含Al2O3≥72wt%,Al2O3+SiO2≥95 wt %;所述石英纤维的平均直径为1~13μm,长度为1~5mm。
进一步地,所述耐火填料中所述滑石粉、苏州土和工业级Al2O3的重量份数比为3~6:3~6:1~1.5。
进一步地,所述滑石粉粉为1000~3000目;所述苏州土为325~800目;所述工业级Al2O3为1500~3000目,其中Al2O3含量≥99%。

本发明的有益效果:
1、本发明中采用滑石粉、苏州土、以及工业级Al2O3作为耐火填料,使得纤维板坯体在煅烧的过程中生成堇青石粉。耐火填料粉体发生化学反应后生成的堇青石粉会更好地填充于纤维交织的空隙之中作为耐火填料的主体,而不是松软的粉体堆积,因此本发明的耐火填料具有极低的热膨胀系数和优良的耐高温性,为纤维板提供刚性支撑,高温下能很好的保护纤维且极大增强了纤维板的抗热震性能;2、采用无机复合纤维的方式,有利于不同纤维的交织,提高坯体的均匀性,增强了纤维板使用寿命,不易粉化;3、本发明中的多晶莫来石纤维和石英纤维质地坚韧,强度高,堆积紧密,纤维板密度高,抗压强度≥3MPa,可做承重板或者钢包等内衬,具有较好的隔热性和刚性强度;4、本发明的纤维板SiO2占比高,导热系数小。5、本发明提供的制备方法不需要对纤维进行短切预处理,简化工艺流程,节省成本。
