Description

一种木屑粘合剂
技术领域
本发明涉及一种粘合剂，具体涉及一种粘接木屑用的粘合剂。
背景技术
木屑是木材加工产生的锯末、刨花等剩余木料，添加粘合剂后，通过热压成型可以加以利用制造刨花板、纤维板和具有特殊造型的木质工艺品等。目前木屑的热压粘合是使用的″三醛胶″，即脲醛胶、酚醛胶和三聚氰胺-甲醛聚合物胶水，尤其以脲醛胶使用做多。这些粘合剂中都含有甲醛成分，而甲醛易致癌，对人们的生命健康造成威胁。目前已有人开发植物蛋白胶作为环保胶水用于木屑的粘接，但是植物蛋白易变质腐烂，且耐水性不佳。本发明的粘合剂不使用甲醛做原料，从源头杜绝了甲醛的危害，同时粘结力强、胶水固化后硬度高、耐水性极佳。
发明内容
为解决传统″三醛胶″的甲醛危害和植物蛋白胶耐水性不佳的问题，本发明提供了一种环保的耐水性极佳的木屑用粘合剂。
一种木屑粘合剂，包含以下重量份的组分二苯基甲烷二异氰酸酯10-50份，蓖麻油1-10份，聚乙二醇10-30份，三羟甲基丙烷1-5份，氯化石蜡5-20份，碳酸钙20-40份，二丁基锡二月桂酸0.1-0.5份，三乙烯二胺0.1-5份。
优选的，所述的二苯基甲烷二异氰酸酯为2，4′-MDI和4，4′ -MDI各占50％的液态MDI(MDI-50)。
优选的，所述的聚乙二醇分子量为100-5000，优选的是 200-1000。
优选的，所述的碳酸钙为重质碳酸钙、轻质碳酸钙、超细碳酸钙、活性碳酸钙中的一种或几种。优选的是轻质碳酸钙。更为优选的是粒径为50-500目的轻质碳酸钙。
本发明的粘合剂固化后邵尔硬度达到3H，100℃沸水蒸煮试样8小时，试样强度下降小于15％。
具体实施方式
下面将结合本发明实施例对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
