Description

一种由LVL工艺的多层胶合板再次深加工的胶合板及其工艺
技术领域
本发明涉及胶合板生产相关技术领域，具体是一种由LVL工艺的多层胶合板再次深加工的胶合板及其工艺。
背景技术
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。
胶合板是家具常用材料之一，为人造板三大板之一，亦可供飞机、船舶、火车、汽车、建筑和包装箱等作用材。一组单板通常按相邻层木纹方向互相垂直组坯胶合而成，通常其表板和内层板对称地配置在中心层或板芯的两侧。用涂胶后的单板按木纹方向纵横交错配成的板坯，在加热或不加热的条件下压制而成。层数一般为奇数，少数也有偶数。纵横方向的物理、机械性质差异较小。常用的胶合板类型有三合板、五合板等。胶合板能提高木材利用率，是节约木材的一个主要途径。
现有的胶合板静曲强度低各行业只能依靠进口实木或砍伐现有自然林的硬木质树种，，对于普通木材而已，生产出的胶合板在应用家具家私重型包装机械行业时承重能力不足，有待于进一步的改进。

作为本发明的一种优选技术方案，所述胶合板条包括多个段状板，每两个相邻的组合板层所包含的胶合板条中的段状板垂直设置。
一种由LVL工艺的多层胶合板再次深加工的胶合板的工艺，包括以下步骤：
S1：将初始胶合板分切，形成多个大小相同的胶合板条；
S2：将多个胶合板组合形成组合板层，一个组合板层内的所有胶合板条中的段状板均同为水平或竖直；
S3：将两个外层板之间填充有多个组合板层；
S4：将每两个相邻的胶合板条、胶合板条与外层板之间均涂设有胶合剂，在胶合情况下胶合板条与外层板形成一个整体，得到深加工板粗胚；
S5：将深加工板粗胚进行上下热压，然后再进行两侧热压，得到深加工胶合板成品。
作为本发明的一种优选技术方案，每两个相邻的组合板层之间均铺设有高强度纤维。
作为本发明的一种优选技术方案，所述胶合剂为市售胶合剂。
本发明具有以下有益之处：本发明通过采用多个胶合板条进行多方向排布，再次压合深加工形成胶合板，能够有效的增加深加工后胶合板的强度，在应用家具家私重型包装机械行业时能够具备优良的承重效果，实用性强，且取材方便，生产成本低。
