摘要
研制了聚乙烯酸缩甲醛磷酸化改进白乳胶，探索了物料及用量选择及反应条件对乳胶性能的影响，合成了性能较为优良的改性胶，其粘度增加到5000mPa·s，剪切强度达14MPa，该产品在耐水性、稳定性等方面都有显著提高。
An adhesive of polyvinyl formal, with good stability and waterproof, was modified by phosphoric acid, the amount of materials and reaction conditions were discussed. The adhesive stength was up to 5000 mPa·s and shear resistance was 14 MPa.
