Description

一种新型胶合板用脲醛胶粘剂
技术领域
本发明属于胶粘剂技术领域,更具体是涉及一种新型胶合板用脲醛胶粘剂。
背景技术
由不同纹理方向的单板胶合而成的一种木质人造板。其相邻层单板纹理通常互成90°角。结构多为奇数层,特殊情况下也有制成4层、6层等偶数层的。由于胶合板有变形小、幅面大、施工方便、不易翘曲、横纹抗拉强度大等特点,在家具、车厢、造船、军工、包装及其他工业部门获得广泛应用。
胶合板板在使用及安装时经常需要使用胶粘剂,胶粘剂性能的好坏对于其使用效果有着极为重要的影响。
发明内容
本发明的目的在于克服现有技术存在的不足,提供一种新型胶合板用脲醛胶粘剂。
为达到上述目的,本发明采取了如下的技术方案:
一种新型胶合板用脲醛胶粘剂,以重量份计,由以下组分组成:
25%质量浓度甲醛溶液:20~30,聚乙烯醇:6~8,
三乙醇胺:1~3,甲基丙烯酸:3~6,
氢氧化钠:0.2~0.4,水:30~50。
上述技术方案中,所述的新型胶合板用脲醛胶粘剂制备工艺为:按配方,将各种组分混合,搅拌均匀后即可得成品。
与现有技术相比,本发明具有产品性能好、制备工艺简单、成本低廉等有益效果。
具体实施方式
以下结合具体实施例对本发明作进一步的描述。
