摘要
研究建筑工业用聚乙烯醇缩甲醛胶粘剂的合成方法,并利用尿素改性,除去游离甲醛,使产品不再有不良气味;继而通过在胶粘剂中加入吸水性强的4A沸石,制备出建筑物用防潮涂料。
The synthesis of the polyvinyl formal adhesive for building engineering and the modification by using the urea is reported the bad odor of the product can be remored by this synthesis. At the end,zeolite 4A is added to adhesive,so that, the moisture-proof paint for buildings is prepared.
