Description

一种木质胶合板及其制作方法
技术领域
本发明涉及木质胶合板技术领域,特别涉及一种木质胶合板及其制作方法。
背景技术
木质胶合板是一种广泛使用的建筑和装饰材料,常用的胶合板类型有三合板、五合板等。胶合板是由木段旋切成单板或由木方刨切成薄木,再用胶粘剂胶合而成的三层或多层的板状材料,通常用奇数层单板,并使相邻层单板的纤维方向互相垂直胶合而成。木质胶合板能提高木材利用率,是节约木材的一个主要途径。
木质材料本身的易燃性导致木质胶合板在使用过程中需要满足防火的要求,因此,市场开始研制各种类型的阻燃胶合板。
现有技术中阻燃胶合板的生产中存在一个问题:阻燃板层与胶黏剂配合使用中的适应性不佳,经常出现板层粘接不牢,导致阻燃胶合板结构破坏。
发明内容
本发明提供了一种木质胶合板及其制作方法,解决了现有阻燃板层与胶黏剂配合使用中的适应性不佳,经常出现板层粘接不牢的技术问题,实现了提高阻燃板层与其他层板粘接牢固性的技术效果。
本发明所提供的一种木质胶合板包括:多块木质层板、第一胶合层、第二胶合层、两块阻燃层板及两块表层板,其中,
相邻所述木质层板通过所述第一胶合层粘接固定形成板芯;
两块所述阻燃层板通过所述第二胶合层粘接固定在所述板芯的顶面和底面上;
所述表层板通过所述第二胶合层粘接固定在对应的所述阻燃层板外;
所述第一胶合层为胶黏剂层;
所述第二胶合层为浸有胶黏剂的无纺布层。
作为优选,所述表层板为表面设置有装饰纹路的所述木质层板。
作为优选,所述胶黏剂为酚醛树脂胶。
作为优选,所述阻燃层板通过所述木质层板在阻燃剂中浸泡制得。
基于同样的发明构思,本申请还提供了一种所述木质胶合板的制作方法,包括以下步骤:
将所有木质层板进行干燥处理,
取干燥后的所述木质层板中的两块浸入阻燃剂溶液中进行浸泡处理,获得所述阻燃层板;
将若干所述无纺布浸入胶黏剂中进行浸泡处理,获得所述第二胶合层;
将所述木质层板的表面涂覆所述胶黏剂并进行热压,形成所述板芯;
将所述阻燃层板通过所述第二胶合层热压到所述板芯的顶面和底面;
将所述表层板通过所述第二胶合层热压到所述阻燃层板的外面。
作为优选,所述木质层板浸入阻燃剂溶液中进行浸泡处理的浸泡时间为5~12h。
作为优选,所述无纺布浸入胶黏剂中进行浸泡处理的浸泡时间为20~30h。
本申请实施例中提供的一个或多个技术方案,至少具有如下技术效果或优点:
通过采用由多块木质层板、第一胶合层、第二胶合层、两块阻燃层板及两块表层板组成的木质胶合板,相邻木质层板通过第一胶合层粘接固定形成板芯;两块阻燃层板通过第二胶合层粘接固定在板芯的顶面和底面上;表层板通过第二胶合层粘接固定在对应的阻燃层板外;第一胶合层为胶黏剂层;第二胶合层为浸有胶黏剂的无纺布层。无纺布层能有效增强阻燃板层与其他层板的粘接牢固性。这样,解决了现有阻燃板层与胶黏剂配合使用中的适应性不佳,经常出现板层粘接不牢的技术问题,实现了提高阻燃板层与其他层板粘接牢固性的技术效果。
