| 目的 提高丙烯酸酯共聚乳液胶粘剂的粘接强度，运用响应面法对丙烯酸酯共聚乳液胶粘剂的配方进行优化。方法 将硬单体和软单体的质量比、乳化剂质量分数、引发剂质量分数、丙烯酸质量分数作为考察因素，以丙烯酸酯共聚乳液胶粘剂在PE板上的剥离强度作为因变量，利用Design-Expert软件对2个自变量进行多次拟合，建立相应的数学模型和三维曲面，得到最优的丙烯酸酯共聚乳液胶粘剂配方，最后加以实验验证。结果 二项式是描述因变量和自变量之间的最佳模型，当硬单体和软单体的质量比值为2.09、乳化剂质量分数为1.56%、引发剂质量分数为0.54%、丙烯酸质量分数为6.16%时，能够获得最大的剥离强度。剥离强度为5.36 kN/m时，混合制成的丙烯酸酯共聚乳液胶粘剂在PE板上的剥离强度最优，即得到最优的丙烯酸酯共聚乳液胶粘剂配方。结论 将响应面实验设计方法应用于优化丙烯酸酯共聚乳液胶粘剂配方，可减少实验次数，且对丙烯酸酯共聚乳液胶粘剂在PE板上的剥离强度具有较好的预测效果。 |

| Abstract: |
| The work aims to improve the adhesion strength of acrylate copolymer emulsion adhesive and optimize the formula for the acrylate copolymer emulsion adhesive in the response surface method. With the mass ratio of hard monomer to soft monomer and the mass fractions of emulsifier, initiator and acrylic acid as the investigation factors, and the peel strength of acrylate copolymer emulsion adhesive on the PE plate as the dependent variable, multiple fittings of two independent variables were conducted with the software Design-Expert. The corresponding mathematical model and 3D surface were established to obtain the optimal formula for the acrylate copolymer emulsion adhesive. Finally, the formula was verified by the experiment. The binomial expression was the best model to describe the dependent variables and independent variables. When the mass ratio of hard monomer to soft monomer was 2.09, and the mass fractions of emulsifier, initiator and acrylic acid were respectively 1.56%, 0.54% and 6.16%, the maximum peel strength could be obtained. When the peel strength was 5.36 kN/m, the peel strength of the blended acrylate copolymer emulsion adhesive on the PE plate was the optimal, namely the optimal formula for the acrylate copolymer emulsion adhesive. In conclusion, the response surface experiment design method applied to the formula for the acrylate copolymer emulsion adhesive can reduce the number of experiments and it can better predict the peel strength of acrylate copolymer emulsion adhesive on the PE plate. |
