Description
技术领域
本发明涉及一种三聚氰胺纸饰面板基板及制造方法,属于人造板生产制造技术领域。
背景技术
随着装饰装修行业发展,家具现场制作越来越少,而全屋定制家具越来越受到大众的欢迎。一方面定制家具是先设计后安装,在设计初期就可以让消费者直观的感受到安装效果,而且消费者可以随意选择自己想要的花色和样式。另一方面家具在工厂制作,现场安装,可以有效减少现场制作的环境问题,因此定制家具的兴起不可避免。
全屋定制这个行业多采用三聚氰胺饰面板作为定制家具生产的主材,然而以多层板和木工板饰面后的板材,在实际应用过程中,总是不可避免的出现开裂等情况。其主要原因是多层板和木工板,在生产过程中以实木面皮和科技木皮为主要贴面材料,这两种材料在温度、空气湿度等的影响下,面皮不可避免的出现局部收缩,应力释放不均匀而开裂的现象,尤以贴完三胺纸的板材最为明显。
在三胺基板生产过程中,以实木面皮或科技木板做为面层材料时,如果基板生产过程中腻修不到位,在贴三胺纸的过程中,总是会出现烧焦、碳化、内部缺陷外显的现象,造成产品的合格率严重下降。
发明内容
为了克服现有技术的不足,本发明提供一种三聚氰胺纸饰面板基板及制造方法。
一种三聚氰胺纸饰面板基板,中间芯层的一面与上拌胶木粉层连接,中间芯层的另一面与下拌胶木粉层连接,上拌胶木粉层与下拌胶木粉层之间连接多层中间芯层。
木工板连接在2层中间芯层的之间。上拌胶木粉层及下拌胶木粉层是木粉拌胶后直接热压在中间芯层或木工板的表面。中间芯层包括木材纵结构层及木材横结构层。
一种三聚氰胺纸饰面板基板的制造方法,含有以下步骤:
包括选择多层板或木工板,通过木粉拌胶工艺步骤、铺装工艺步骤、预压工艺步骤、热压工艺步骤及抛光工艺步骤,制作的三胺基板一共有三层结构构成,上下两层均为木粉层,中间芯层为多层板或木工板。
本发明的优点是这样的组合方式,主要目的是为了解决传统以多层板和木工板为基础人造板,在贴合实木面皮或科技木皮后,再敷贴三聚氰胺纸后,存在的烧焦、碳化、开裂、内部缺陷暴露等等一系列问题,另一方面可以克服实木面皮日渐紧缩的情况,减少企业生产原材料单一受限问题。
