成果概况

本发明提供了一种脲醛树脂胶粘剂的添加剂及其制备方法。所述脲醛树脂胶粘剂的添加剂由按重量份计的改性木粉100份、橡子淀粉50-100份、脱硫石膏50-500份组成,其是将改性木粉、橡子淀粉、脱硫石膏混合均匀制备得到。所述脲醛树脂胶粘剂的添加剂能够代替面粉加入到脲醛树脂中,制备人造板时,赋予胶粘剂良好的预压性,保证人造板高生产效率,同时能够有效降低人造板甲醛释放量,提高了人造板物理力学性能。


专利情况

The invention provides an additive of a urea formaldehyde resin adhesive and a preparation method thereof. The additive of the urea formaldehyde resin adhesive is prepared from the following components in parts by weight: 100 parts of modified wood flour, 50-100 parts of acorn starch and 50-500 parts of desulfurized gypsum. The additive is prepared by uniformly mixing the modified wood flour, acorn starch and desulfurized gypsum. The additive of the urea formaldehyde resin adhesive can be used for replacing flour to be added into urea formaldehyde resin, so that when an artificial board is manufactured, the adhesive has a good pre-pressing property, thereby ensuring high production efficiency of the artificial board, effectively reducing the release amount of the formaldehyde in the artificial board, and improving the physical and mechanical properties of the artificial board.
