Abstract

A large number of factors, including the wood surface and the composition of an adhesive, influences the quality of adhesive bonding and the performance properties of adhesive wood products. Considering that there is a need for low-toxicity adhesive wood materials, one promising area is the unification of an adhesive formulation for various plants and the development of adhesives to decrease the toxicity of final products. The introduction of modifiers and fillers into the composition of adhesive resins for plywood allows one not only to decrease an amount of toxic substances, but also to increase the productivity of pressing equipment by accelerating the curing of an adhesive. The state and properties of urea–formaldehyde resins and their adhesives are studied in this work. It shows that there is a need to modify adhesive resins for plywood, which also decreases the cost of resources and the energy to produce glued wood materials. An adhesive composition developed. The test results and the conclusion are presented. The recommendations are given for the unification of adhesive formulation.

胶合板胶粘剂成分的优化

摘要

许多因素，包括木材表面和粘合剂的成分，都会影响粘合剂的粘合质量和粘合木制品的性能。考虑到对低毒性粘合木质材料的需求，一个有前途的领域是统一各种植物的粘合剂配方以及开发粘合剂以降低最终产品的毒性。在胶合板用粘合剂树脂组合物中引入改性剂和填料不仅可以减少有毒物质的量，而且可以通过加速粘合剂的固化来提高压制设备的生产率。这项工作研究了脲醛树脂及其粘合剂的状态和性能。这表明需要对胶合板的粘合树脂进行改性，这也降低了生产胶合木材料的资源和能源成本。开发了粘合剂组合物。给出了测试结果和结论。给出了粘合剂配方统一的建议。
