Description

一种乙酰化阻燃型碳纤维复合木板及其生产工艺
技术领域
本发明涉及一种复合木板,具体是涉及一种乙酰化阻燃型碳纤维复合木板及其生产工艺。
背景技术
木材是由90%的纤维素、半纤维素、木质素、水及10%的抽提物和灰分等组成,主要化学成分的分子结构、性质及相互间的关系不仅是木材各种性质的物质基础,也是木材改性和阻燃处理的化学基础。
阻燃木材的阻燃性能与阻燃剂的性能和用量有关,还与阻燃剂在木材中的分布状态有关。阻燃处理对木材强度、吸湿性等的影响取决于所用阻燃剂的种类、酸碱性及处理工艺条件。因此,选择合适的阻燃处理工艺,既能提高阻燃性能,而又不破坏木材的物理力学性能和工艺性能。
木材的阻燃处理方法有很多,主要有常压浸注法、热压法、复合法等。常压浸注法就是在常压条件下,将阻燃剂溶液注入到木材或木质人造板中,该方法工艺简单、成本低廉、设备投资少,缺点是只适于处理单板等厚度较薄(1~3cm)的材料,以及渗透性能较好的材质。热压法适用于人造板生产,对板材的物理力学性能影响很小,但在通过热压将阻燃剂渗入板内时,易使板材表面鼓泡。复合法是在人造板生产中,在胶粘剂或木纤维中拌入阻燃剂,但阻燃剂的加入会影 响胶粘剂的固化。
发明内容
本发明的目的是为了克服上述现有技术所存在的缺点和不足,提供一种乙酰化阻燃型碳纤维复合木板及其生产工艺。
为了达到上述目的,本发明采用如下技术方案:
一种乙酰化阻燃型碳纤维复合木板,由普通木板和碳纤维层组成,通过将普通木板采用溶剂浸没,蒸汽干燥,阻燃剂浸泡、溶剂稀释的酸酐酰化反应后,干燥,与碳纤维结构层胶粘复合制成。
上述所述普通木板为厚度5~10cm的木质板材。
上述所述碳纤维结构层的层厚为2mm,所述的碳纤维为聚丙烯腈基碳纤维、沥青基碳纤维和酚醛基碳纤维中的任一种。
上述所述胶粘采用的胶粘剂为阻燃胶粘剂
一种乙酰化阻燃型碳纤维复合木板的生产工艺,包括以下步骤:
(1)将普通木板放入反应釜中,并加入溶剂将其完全浸没10~15min,在100~120℃下进行蒸汽干燥,抽真空至100~200Pa,得到含水量为8~15%的木板;
(2)采用浓度10~15%的阻燃剂浸没步骤1)得到的木板,加压至1MPa,维持20~30min,卸压、卸阻燃剂,抽真空至100~200Pa,再加入溶剂至将木板完全浸没10~15min,在100~120℃下进行蒸汽干燥,抽真空至100~200Pa,得到含水量为5~12%的木板;
(3)采用溶剂稀释酸酐,得到浓度为20~40%的酸酐,采用浸泡的方式,加到步骤2)所得的木板中,在1MPa、100~130℃下反应8~16h,反应结束后,排 出液体,抽真空至100~200Pa,得到含水量为5~10%的木板;
(4)向步骤3)所得的木板中添加溶剂,浸没10~15min,再在100℃~120℃下进行蒸汽干燥,抽真空至100~200Pa,得到含水量为5~10%的木板;
(5)在常温常压下,采用阻燃胶粘剂将步骤4)得到的木板的其中一面与片状的碳纤维胶粘,压合,得到乙酰化阻燃型碳纤维复合木板。
上述所述的溶剂为苯、甲苯、乙苯中的任一种,优选为苯。
上述所述的阻燃剂为浓度为10%的KD-I、FRW、磷酸二氢氨一硼酸(MAP-H3BO3)、N-羟甲基-3-(二甲氧基磷酰基)丙酰胺中的任一种,优选为KD-I。
上述所述的酸酐为甲酸酐、乙酸酐、苯甲酸酐、苯乙酸酐中的任一种,优选为乙酸酐。
与现技术相比,本发明的优点和有益效果主要有:
1、本发明制得的复合木板遇明火不会燃烧,只能轻度炭化,极大改变了木材阻燃的性质,拓宽了木材的应用范围,而且复合木板尺寸稳定,在潮湿暴露条件下,木材膨胀少于15%,阻燃木材氧指数超过42%,烟密度小于43kg/m3并有抗木菌和白蚁的侵袭性,抗老化,且不降低抗冲击强度,湿抗压强度提高一倍,顺纹抗压强度>100MPa,抗弯强度>200MPa,端面硬度>10000N,密度>0.8g/cm3。
2、本发明生产工艺简单,成本低,适合用于处理厚度为1~5cm的普通木板,制得的复合木板表面平滑,不会鼓泡。
3、本发明生产工艺步骤(2)中,反应结束后将阻燃剂排出,经过滤分离、添加阻燃剂等操作,可重复使用。生产工艺步骤(3)、(4)中,反应结束后将液体排出,经蒸馏分离,可得到溶剂苯、乙酸酐及乙酸溶液。可重复利用率高, 因此成本低。
