一种室内装饰用新型淀粉胶粘剂制备及性能研究

Preparation and performance study of a new type of starch adhesive for interior decoration

为了制备出与我国标准相符用于室内装饰胶合板材料,对生物油-淀粉胶粘剂展开研究,以生物油、淀粉为主要原材料,试验因子包括淀粉乳液浓度、生物油加入量、丙烯酰胺、过硫酸铵等,评价试验中胶粘剂的性能指标主要包括固含量、胶合强度、黏度,使用正交试验法成功优选最有性能的改性淀粉胶粘剂的工艺。试验结果发现,在40%淀粉乳液质量分数、20%丙烯酰胺、25%过硫酸铵、20%生物油时,能够成功制备综合性能最优的室内装饰胶合板,储存期15 d时,最终1.44 MPa的胶合强度满足我国对Ⅲ类胶合板的制备要求。

In order to prepare plywood materials for interior decoration in line with the national standards,the bio oil starch adhesive was studied.With bio oil and starch as the main raw materials,the test factors included the concentration of starch lotion,the amount of bio oil,acrylamide,ammonium persulfate,etc.The performance indicators of the adhesive in the evaluation test mainly included solid content,bonding strength,viscosity,and the orthogonal test method was used to successfully optimize the process of the most high-performance modified starch adhesive.The test results showed that The results showed that the interior decoration plywood with the best comprehensive performance could be successfully prepared at 40%starch emulsion mass fraction,20%acrylamide,25%ammonium persulfate and 20%bio-oil,and the final gluing strength of 1.44 MPa met the requirements of China for the preparation of class Ⅲ plywood during the storage period of 15 days.
