Adhesive prepared taking waste paper as raw material, and preparation method thereof

The invention belongs to the technical field of adhesive, and more specifically relates to an adhesive prepared taking waste paper as raw material, and a preparation method thereof. The adhesive comprises, by weight, 40 to 100 parts of waste paper, 0 to 5 parts of an oxidizing agent, 40 to 100 parts of vegetable protein powder, 10 to 20 parts of a cross-linking agent, 0.5 to 6 parts of an alkali,and 200 to 800 parts of water. The environment-protection timber adhesive is capable of realizing waste paper recycling, is low in cost, is quick in curing speed; no formaldehyde is released in production and using process; at 130 DEG C, 3min, 1.0MPa hot pressing conditions, three-layer glued boards are prepared, and the performance is capable of reaching that required in GB/T9846-2015. 本发明属于胶黏剂技术领域，具体涉及种以废纸为原料制备的胶黏剂及其制备方法。所述种以废纸为原料制备的胶黏剂，其原料按重量份计包括：废纸40-100份、氧化剂0-5份、植物蛋白粉40-100份、交联剂10-20份、碱0.5-6份、水200-800份。本发明制备的环保型木材胶黏剂实现了废纸的重新利用，成本低，生产及使用过程无甲醛释放；固化速度快，以130℃、3min、1.0MPa的条件，热压制备的3层胶合板，性能可达到GB/T9846-2015中II类胶合板的要求。
