本发明还提供了一种生物基MDI粘合的欧松板的制备方法，包括以下步骤：
(1)取板材，在干燥后置于滚筒中；
(2)根据板材重量，将生物基MDI胶水按比例加入滚筒中，并进行混合；
(3)将混合了生物基MDI胶水的板材层叠平铺于压缩加热用箱体中；
(4)将箱体上板对箱体中的层叠板材施加压力，并加热；
(5)将步骤(4)中处理的层叠板材脱模粘结后，冷却后裁切修边，制得欧松板。

实施例1：
如图1-3所示，一种生物基MDI粘合的欧松板，包括板材100，板材100共设置有多个，相连板材100之间设置有生物基MDI胶水 200，每个板材100均包括基材层110，基材层110的两侧均设置有防护层120，基材层110内设置有多个加强筋111。
在本实施例中，通过设置的加强筋111，能够增强板材100的强度，通过基材层110能够实现隔音效果，提升板材100的隔音，防护层120能够保证板材100的防撞击弹性，进而能够对板材100进行保护，生物基MDI胶水200会与板材100中残留水分等含活性氢的物质反应交联，从而粘结板材100成为欧松板。
进一步的，每个板材100内均设置有工型件130，工型件130的两端分别位于基材层110和防护层120内。
在本实施例中，通过将工型件130设置到基材层110和防护层 120内，能够增强基材层110和防护层120的连接强度。
进一步的，基材层110内开设有填充槽112，填充槽112内设置有隔音棉113。

进一步的，防护层120内开设有安装槽121，安装槽121内安装有弹性环122。
在本实施例中，通过在安装槽121内安装有弹性环122，使得板材100在受到撞击时，具有一定的缓冲，能够对板材100进行保护，延长了板材100的使用寿命。
进一步的，板材100为木质、竹质或者秸秆类板中的任意一种。
在本实施例中，板材100可以使用木质、竹质或者秸秆类板，使得板材100的材料具有多样性，以满足不同的使用需求。
进一步的，生物基MDI胶水200由生物体提取的甲苯合成。

(4)将箱体上板对箱体中的层叠板材100施加压力，并加热；
(5)将步骤(4)中处理的层叠板材100脱模粘结后，冷却后裁切修边，制得欧松板。
进一步的，在步骤(3)中，层叠的层数为10-20层。
此外，本发明还提供了生物基MDI粘合的欧松板的家装产品，例如家具、装饰板等。
本发明采用生物基MDI胶水作为粘合剂，生物基MDI胶水所用甲苯，全部或部分来自于生物体而非石油，制备出无甲醛的欧松板，同时，还具有良好的隔音效果，并且还具有较好的强度以及防护效果，从而能够延长所制备的欧松板的使用寿命。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不会使相应技术方案的本质脱离本发明技术方案的保护范围。
