Description

一种重组功能型科技木制备方法、科技木及隔板
技术领域
本发明属于重组功能型科技木领域，具体来说，涉及一种重组功能型科技木制备方法、科技木及隔板。
背景技术
随着社会的进步，人们对木材的性能要求越来越高，例如具有防火性能、防水性能等。而原始木材通常不具有这些性能。另外资源的耗竭，使得功能型科技木应运而生。科技木是以普通木材(速生材)为原料，利用仿生学原理，通过对普通木材、速生材进行各种改性物化处理生产的一种性能更加优越的全木质的新型装饰材料。与天然材相比，几乎不弯曲、不开裂、不扭曲。现有的功能型科技木的制备方法复杂，需要大量使用化学试剂，不利于环保。
发明内容
为解决上述技术问题，本发明提供一种重组功能型科技木制备方法、科技木及隔板，具有良好的防火、防水性能，且方法简单。
为解决上述技术问题，本发明实施例采用以下技术方案：
第一方面，本发明实施例提供一种重组功能型科技木制备方法，所述方法包括：
将速生木材刨削成第一颗粒；
将所述第一颗粒浸泡在阻燃剂溶液中，然后晾干，形成第二颗粒；
通过热压工艺将第二颗粒制成第一板材；
对第一板材表面进行预处理，利用热压工艺，形成第二板材；
在第二板材外表面进行防水处理，形成重组功能型科技木。
优选的，所述第一颗粒的粒径小于3毫米。
优选的，所述阻燃剂溶液按照重量份数，包括以下组分：
硫酸铵：30份；
聚磷酸铵：10份；
分散剂：1份；
水：600份。
优选的，所述第二颗粒内部含有阻燃剂，表面包覆有阻燃剂层。
优选的，所述通过热压工艺将第二颗粒制成第一板材，包括：向第二颗粒加入粘结剂，采用热压工艺，将第二颗粒制成第一板材；所述热压工艺中，温度为100～110℃，压力为0.8～1MPa，时间4～6min。
优选的，所述对第一板材表面进行预处理，包括：向第一板材表面贴敷玻璃纤维基布，并向玻璃纤维基布上涂覆聚四氟乙烯树脂。
优选的，所述利用热压工艺，形成第二板材中，温度为70～80℃，压力为1MPa，时间1～2min。
优选的，所述在第二板材外表面进行防水处理，包括：将纤维基布在防水溶液中浸渍3—5分钟后，取出待晾干后，将纤维基布贴敷在第二板材外表面，采用热压工艺压制成型；所述热压工艺中，温度为50～60℃，压力为1MPa，时间1～2min。
第二方面，本发明实施例提供一种重组功能型科技木制备方法制成的科技木，包括板材本体，以及设置在板材本体外表面的防火层和防水层；所述防火层包括玻璃纤维基布和聚四氟乙烯树脂层，玻璃纤维基布覆盖在板材本体外表面，聚四氟乙烯树脂层覆盖玻璃纤维基布；所述防水层包括纤维基布，纤维基布在防水溶液中浸渍并晾干，纤维基布和聚四氟乙烯树脂层连接；所述板材本体中包含第二颗粒，所述第二颗粒表面包覆阻燃剂层，第二颗粒中含有阻燃剂。
第三方面，本发明实施例提供一种含有上述的科技木的隔板，包括由科技木制成的第一板体和第二板体，以及干燥剂层和吹气装置，第一板体和第二板体连接成一体，且防水层位于外侧，形成墙体；墙体的中部开设有凹槽，凹槽的顶端开口，干燥剂层位于凹槽的顶部，且布满凹槽顶端开口；吹气装置的出气端和凹槽顶端相通。
上述实施例的重组功能型科技木制备方法、科技木及隔板，具有良好的防火、防水性能。本实施例科技木制备方法中，第一颗粒浸泡在阻燃剂溶液中，然后晾干，形成第二颗粒。第二颗粒内部含有阻燃剂，表面包覆有阻燃剂层。这样，第二颗粒不仅内部，而且外部也含有阻燃剂，使得第二颗粒的防火性能明显提高。在向第一板材表面贴敷玻璃纤维基布，并向玻璃纤维基布上涂覆聚四氟乙烯树脂，形成一层复合织物，具有耐高温的特征。依靠纤维基布以及聚四氟乙烯树脂，使得整个板材的防水性能提高。本实施例科技木制备方法过程简单，易于工业化，且环境污染小。
附图说明
图1是本发明实施例的隔板的结构示意图。
图中有：1第一板体、2第二板体、3干燥剂层、4吹气装置、5凹槽。
具体实施方式
下面对本发明的技术方案进行详细的说明。
本实施例提供一种重组功能型科技木制备方法，包括：
步骤10)将速生木材刨削成第一颗粒。
步骤20)将所述第一颗粒浸泡在阻燃剂溶液中，然后晾干，形成第二颗粒。
步骤30)通过热压工艺将第二颗粒制成第一板材。
步骤40)对第一板材表面进行预处理，利用热压工艺，形成第二板材。优选的，所述利用热压工艺，形成第二板材中，温度为70～80℃，压力为1MPa，时间1～2min。
步骤50)在第二板材外表面进行防水处理，形成重组功能型科技木。
上述实施例中，第一颗粒浸泡在阻燃剂溶液中，然后晾干，形成第二颗粒。第二颗粒内部含有阻燃剂，表面包覆有阻燃剂层。这样，第二颗粒不仅内部，而且外部也含有阻燃剂，使得第二颗粒的防火性能明显提高。优选的，所述第一颗粒的粒径小于3毫米。第一颗粒的粒径过大，会使得浸泡在阻燃剂溶液中后，阻燃剂无法完全浸入第一颗粒或者作业时间过长。
本实施例中，优选的，所述阻燃剂溶液按照重量份数，包括以下组分：硫酸铵：30份；聚磷酸铵：10份；分散剂：1份；水：600份。
优选的，所述通过热压工艺将第二颗粒制成第一板材，包括：向第二颗粒加入粘结剂，采用热压工艺，将第二颗粒制成第一板材；所述热压工艺中，温度为100～110℃，压力为0.8～1MPa，时间4～6min。采用热压工艺，将第二颗粒制成第一板材，由于第二颗粒内外部都含有阻燃剂，所以制成的第一板材也具有良好的阻燃性能。
优选的，所述对第一板材表面进行预处理，包括：向第一板材表面贴敷玻璃纤维基布，并向玻璃纤维基布上涂覆聚四氟乙烯树脂。通过对第一板材表面进行预处理，进一步提升第一板材的阻燃性能。在向第一板材表面贴敷玻璃纤维基布，并向玻璃纤维基布上涂覆聚四氟乙烯树脂，形成一层复合织物，具有耐高温的特征。
优选的，所述在第二板材外表面进行防水处理，包括：将纤维基布浸渍在防水溶液中3—5分钟后，取出待晾干后，将纤维基布贴敷在第二板材外表面，采用热压工艺压制成型；所述热压工艺中，温度为50～60℃，压力为1MPa，时间1～2min。纤维基布具有的耐高温性能。浸渍以后，纤维基布表面形成防水涂层，同时纤维基布内部也吸附有防水溶液。聚四氟乙烯树脂不吸水。这样，依靠纤维基布以及聚四氟乙烯树脂，使得整个板材的防水性能提高。
上述制备方法简单实用。通过上述方法制备的科技木具有良好的防火性能和防水性能。在建筑领域中，对部件通常有防火、防水性能的要求，例如房间隔板。使用本实施例的方法制备的科技木，可以实现上述目的。
本实施例还提供上述的重组功能型科技木制备方法制成的科技木，包括板材本体，以及设置在板材本体外表面的防火层和防水层；所述防火层包括玻璃纤维基布和聚四氟乙烯树脂层，玻璃纤维基布覆盖在板材本体外表面，聚四氟乙烯树脂层覆盖玻璃纤维基布；所述防水层包括纤维基布，纤维基布在防水溶液中浸渍并晾干，纤维基布和聚四氟乙烯树脂层连接；所述板材本体中包含第二颗粒，所述第二颗粒表面包覆阻燃剂层，第二颗粒中含有阻燃剂。
上述科技木中，本体中包含的第二颗粒，以及玻璃纤维基布和聚四氟乙烯树脂层，使得板材具有良好的耐燃性能。同时，设置纤维基布，使得板材具有良好的防水性能。纤维基布在防水溶液中浸渍。纤维基布和聚四氟乙烯树脂层连接，聚四氟乙烯树脂层具有不吸水性能，使得板材的整体防水性能大大提高。
如图1所示，本发明还提供一种上述实施例的科技木制成的隔板，包括由科技木制成的第一板体1和第二板体2，以及干燥剂层3和吹气装置4，第一板体1和第二板体2连接成一体，且防水层位于外侧，形成墙体；墙体的中部开设有凹槽5，凹槽5的顶端开口，干燥剂层3位于凹槽5的顶部，且布满凹槽5顶端开口；吹气装置4的出气端和凹槽5顶端相通。
该隔板由上述实施例的科技木制成，具有良好的防火和防水性能。同时该隔板还具有防潮防霉性能。开启吹气装置4，将外界空气向凹槽5中灌输。外界空气首先经过干燥剂层3，其中含有的水分被干燥剂层3吸附，干燥后的气体进入凹槽5中，在凹槽5中，通过墙体中的空隙，气体向外流动，在流动过程中，将墙体中的水分带走，从而起到干燥墙体的目的。当工作一段时间后，可以更换干燥剂层3中的干燥剂，确保干燥处理后的空气进入凹槽5中。该结构的隔板还具有防潮防霉性能。
为确保外界空气经过干燥剂层3处理后才进入凹槽5中，优选的，所述的干燥剂层3包括干燥剂颗粒、支撑筒31、位于支撑筒31中的上下布设的第一平板32和第二平板33，第一平板32和第二平板33错位布设，第一平板32和第二平板33分别和支撑筒31筒壁之间有间隙。干燥剂颗粒填充在支撑筒31中。支撑筒31的底面设有直径为0.3毫米的通孔。干燥剂颗粒的粒径从上到下逐渐减小。干燥剂颗粒的粒径为2毫米至0.5毫米。外界空气进入支撑筒31上部，依次穿过第一平板32上方的干燥剂颗粒、第二平板33上方的干燥剂颗粒、第二平板33下方的干燥剂颗粒，从支撑筒31的底面穿出，进入凹槽中。空气从第一平板32和支撑筒31筒壁之间的空隙进入第一平板32和第二平板33之间的空间。空气从第二平板33和支撑筒31筒壁之间的空隙进入第二平板33下方。该过程可以确保外界空气经过干燥后进入凹槽5。第一平板32和第二平板33本身不透气。
本领域技术人员依据上述实施例，可以对本申请进行非创造性的技术改进，而不脱离本发明的精神实质。这些改进仍应视为在本申请权利要求的保护范围之内。
