冷制高强快干系列胶黏剂的制备与性能

Preparation and Performance of Cold System High Strength Quick-Drying Series Adhesive

目前,淀粉改性胶黏剂在瓦楞纸板粘合中得以广泛应用,具体配方与生产工艺很多,但大多不能很好地满足生产工艺要求。介绍了一种冷制高强快干性胶黏剂的配方及制备工艺,该工艺简单易行,不需加温,从投料到制成成品仅需30-90min,粘合的纸箱干燥快、强度高、不跑楞、不吸潮、不泛碱。讨论了该胶黏剂在不同条件下的合成方法,以及不同的原材料、工艺条件对产品性能的影响。实验证明,该产品对瓦楞纸的强度、厚度等性能可明显改善。

At present, the starch modified adhesive is widely applied to corrugated cardboard. Although there are plenty of formulation and production technology, most of the products cannot meet the technical requirements. A formulation of cold system high - strength quick - drying adhesive is introduced as well as the preparation technology. This method is easy to carry out without heating, and there are only 30 -39mins for preparing a complete product. The paper box bonded by this adhesive has many advantages, such as quick drying, high strength, no collapse of corrugated box, no moisture absorption, and no accumulation of alkali. The preparation methods of this adhesive under different conditions and effects of various materials and technique conditions on performance of products are discussed. It is demonstrated that the performances of corrugated paper such as strength and thickness can be improved significantly.
