摘要
通过调整固含量,适当增加聚乙烯醇(PVA)和三聚氰胺用量,并添加少量的甲苯二异氰酸酯(TDI),制备低成本的环保脲醛树脂。实验结果表明,合成脲醛树脂的甲醛释放量达到F1环保指标,初始黏结力、胶合强度等综合指标均符合国家标准,成本则有较大降低。
The lower cost urea-formaldehyde resin of environmental protection was favourably synthesized through reducing the content of mass, increasing further concentration of the polyvinyl alcohol, melamine and appending a small quantity of toluene diisocynate. And it was discovered that the concentration of exonerative formaldehyde of the urea-formaldehyde resin synthesized rea- ches the F1 target of environmental protection, the initial adhesive force and gluing intensity is up to the national standard, but the cost of the resin is reduced obviously.
