低毒脲醛树脂胶黏剂的研究
Research on Low Toxicity Urea-formaldehyde Resin Adhesive

摘要 Abstract

介绍了脲醛树脂的国内研究现状及其性能特点，着重研究了反应机理，根据技术要求，进行了研制工艺的选择，实验方案的确定。主要研究了加入改性剂聚乙烯醇和三聚氰胺之后，改变甲醛与尿素的物质的量的比、反应时间、溶液的pH值和反应温度，制得的脲醛树脂进行对比，以评定它们对树脂性能的影响。
This paper describes the status of research on urea-formaldehyde resin in China and the characteristics of its properties, particular emphasis is placed on the study of its reaction mechanism and the determination on the option of its developing techniques and experimental planning in accordance with the technical requirements. After the addition of modifiers such as polyvinyl alcohol and melamine, this paper then studies the molar ratios, reaction times, pH values and reaction temperatures of the solutions of the modified formaldehyde and urea, as well as concts comparison on the urea-formaldehyde resins proced, so as to evaluate their impact on the resin properties.

采用加入亚硫酸钠，利用玫红酸滴定的方法测试树脂中游离甲醛含量，使得游离甲醛的含量低于2%。详述了反应终点的控制方法，不同反应阶段的反应时间长短，反应温度的限度，pH值的范围及碱——酸——碱地反应路线在实验过程中我们对每次的产品进行了检测，确定了低毒脲醛树脂胶黏剂的最佳配方，同时对各种影响因素进行了分析和讨论，解决了游离甲醛含量低于2%的难题，保证了产品的质量，该胶黏剂有很好的发展前景。
In order to achieve below 2% of free formaldehyde content, the rose acid titration method was used by adding sodium sulfite to test the free formaldehyde content in the resin. The control method of reaction endpoint, the reaction time of different reaction phases, the reaction temperature limits, the range of pH value and the alkali - acid - alkali reaction routes are all elaborated in detail; and the optimum formula of low toxicity urea-formaldehyde resin adhesive has been determined after testing every batch of proct proced in the course of this experiment. At the same time, the problem of maintaining the free formaldehyde content below 2% was resolved by concting analysis and discussions on the various contributing factors. So the proct quality and the promising development prospect of the adhesive is ensured.

摘 要：以苯酚、二甲苯甲醛树脂(XF)和三(2,3-环氧丙基)异氰脲酸酯(又称异氰脲酸三缩水甘油酯,triglycidylisocyanurate,TGIC)为原料,经两步反应合成了一种新型含氮阻燃环氧树脂.采用GPC监测反应过程和转化率、IR和1H-NMR表征了该树脂的结构.通过该两步反应的研究,确定了苯酚改性二甲苯甲醛树脂(PXF)的最佳合成工艺,在碱性条件下PXF树脂与TGIC进行开环反应,制得了TGIC转化率85%以上的含氮环氧树脂,其环氧值在0.30～0.40 eq/100 g可调.
