浙江普利金塑胶有限责任公司研究人员开发出一种聚乙烯醇缩丁醛树脂的制备新方法。该方法包括步骤:将PVA 100份、正丁醛33~45份,溶解在500~700份纯水中,形成混合溶液;向混合溶液中加入共混复合增强型的催化剂1~5份后混合均匀,得到pH=1~3的水 Zhejiang Pulikin Plastic Co., Ltd. researchers developed a new method of preparation of polyvinyl butyral resin. The method comprises the following steps of: dissolving 100 parts of PVA and 33-45 parts of n-butyraldehyde in 500-700 parts of pure water to form a mixed solution; adding 1 to 5 parts of the mixed and compounding reinforced catalyst into the mixed solution and then mixing Uniform, get pH = 1 ~ 3 water
