Polyvinyl butyral resin and preparation method thereof
The invention discloses polyvinyl butyral resin and a preparation method thereof, and belongs to the technical field of high polymer materials, the polyvinyl butyral resin is prepared into 10.0 wt% ethanol solution to be dissolved within 30 min; the viscosity change rate of the 10.0 wt% ethanol solution prepared from the polyvinyl butyral resin is less than 1.5 after the solution is placed for 24 hours; the particle size of the polyvinyl butyral resin ranges from 1.20 to 2.00; the viscosity change is small under the high solid content, the polyvinyl butyral resin is prepared into 10wt% and 20wt% ethanol solutions, and the rotary viscosity V20wt%/V10wt% lt is tested; 20. According to the preparation method provided by the invention, the hydrogen bond breaker is added into the polyvinyl alcohol-water system, so that the hydrogen bond acting force is effectively reduced, and the ceramic slurry has relatively good dispersity and dissolvability when being prepared, and has good market competitiveness.
本发明公开了一种聚乙烯醇缩丁醛树脂及其制备方法，属于高分子材料技术领域，本发明中的聚乙烯醇缩丁醛树脂配置成10.0wt％乙醇溶液30min内溶解；聚乙烯醇缩丁醛树脂配置成10.0wt％乙醇溶液的粘度放置24h粘度变化率＜1.5；聚乙烯醇缩丁醛树脂粒径分布在1.20～2.00范围；高固含下粘度变化小，将聚乙烯醇缩丁醛树脂配置成10wt％，20wt％乙醇溶液，测试旋转粘度，V20wt％/V10wt％<20。本发明提供的制备方法中，在聚乙烯醇‑水体系中加入氢键破坏剂，有效降低氢键作用力，制作陶瓷浆料时有较好的分散性和溶解性，具有良好的市场竞争力。
