改性脲醛树脂胶粘剂制备的研究
Studies on Preparation and Improvement of Urea-formaldehyde Resin
【摘要】 研究了用加入聚乙烯醇和三聚氰胺的方法来改善脲醛树脂胶粘剂的耐热耐水性 ,采用甲醛与尿素低摩尔比的三次缩聚反应使树脂中游离甲醛含量明显提高
【Abstract】 The polycon method includes three-stage densation reaction, with low urea/formaldegyde molar ratio to decrease the content of the free formaldehyde and improve propertie of the product. The polyvingalcohol and melamine are added to improve the water-resistance and heat-resistance of the urea-formaldehyde resin adhesive.
