摘　　要：为了解决工业生产中白胶受温度影响大,在纸箱生产使用时易出现脱粘弹开、胶液飞溅等不良现象,瓦楞纸箱用包装胶在保持原有黏度的同时,应拥有耐高温剪切性能和流变性能。本文以醋酸乙烯酯共聚乳液为主要原料,利用煅烧高岭土和硼酸分别作为增强剂和交联剂,使用聚醚类消泡剂,制备得到了具有耐高温剪切性能的包装胶。采用单因素变量法分别研究了高岭土、硼酸、水和加料方式等因素对胶液黏度和胶膜强度的影响。同时,结合响应面试验法,以黏度和胶膜强度为响应值观察拐点,研究了配方中影响较大的组分对高温高剪切下的黏度、胶膜强度的影响,并结合实际生产筛选出最优配方。研究结果表明:改性胶的最佳配方为,高岭土质量分数为2%,硼酸质量分数为0.227%,水质量分数为4.498%。试验结果与模型优化预测结果相近,表明基于响应面法的设计试验具有现实意义,并验证了响应面法用于瓦楞纸箱用包装胶的耐高温剪切性能研究及配方优化的可行性。In order to solve the problem of white glue being greatly affected by temperature in industrial production,which is prone to debonding,elastic opening,and splashing of adhesive during the production of cardboard boxes,the packaging adhesive used for corrugated carton should have high-temperature resistance shear properties and rheological properties while maintaining its original viscosity.In this paper,vinyl acetate copolymer emulsion was used as the main raw material,calcined kaolin and boric acid were used as reinforcing agent and crosslinking agent respectively,and polyether defoamer was used to prepare packaging adhesive with high-temperature resistance shear properties.The single factor variable method was used to study the effects of factors such as kaolin,boric acid,water,and feeding method on the viscosity of adhesive solution and the adhesive film strength.At the same time,combined with the response surface test method,the inflection point was observed with viscosity and adhesive film strength as response values,and the influence of the components with significant influence in the formulation on viscosity and adhesive film strength under high temperature and high shear was studied,and then the optimal formulation was selected based on actual production.The research results showed that the optimal formulation for modified adhesive was 2%kaolin,0.227%boric acid,and 4.498%water.The experimental results were similar to the model optimization prediction results,indicating that the design experiment based on response surface methodology had practical significance,and verifying the feasibility of using response surface methodology to study the high-temperature resistance shear properties and formulation optimization of packaging adhesive for corrugated carton.
