Abstract

The latex synthesis in the presence of ethylene-propylene copolymer and methacrylic acid (MAA) was considered for this experiment. The kinetic regularities of the synthesis process were determined and the optimal quantities and ratios of the components were determined both experimentally and by mathematical modeling. It was determined that a modified latex with optimal values is obtained when the amount of methacrylic acid in the latex is 5 parts by weight. The absorbent composition was prepared latex-based based on synthesized EPC – + methacrylic acid. The prepared absorbent was impregnated with viscose (22B) and 222K kapron cord and a rubber-cord bond were determined. The findings of the present study show that the aqueous dispersions of EPC latex were synthesized using various emulsifiers with high technological stability. The presence of the main factors affecting the stability and adhesive properties of the EPC aqueous dispersion has been established. It has been shown that the best stability for 6 months is achieved at a pH value of 12.EPC water emulsion was modified in the presence of MAA by graft copolymerization.

甲基丙烯酸乳液基乙烯-丙烯共聚物的合成及应用

本实验考虑了乙烯-丙烯共聚物和甲基丙烯酸(MAA)存在下的乳胶合成。确定了合成过程的动力学规律，并通过实验和数学建模确定了各组分的最佳用量和配比。确定了当甲基丙烯酸的加入量为5份(重量比)时，得到的改性胶乳的最佳值。在合成EPC - +甲基丙烯酸的基础上制备了乳液基的吸水性组合物。用粘胶(22B)和222K卡普纶线浸渍所制得的吸附剂，并测定了胶绳黏结。研究结果表明，采用多种乳化剂合成的EPC乳液水分散体具有较高的工艺稳定性。确定了影响EPC水分散体稳定性和粘接性能的主要因素。研究表明，在pH值为12时，可达到6个月的最佳稳定性。采用接枝共聚法在MAA存在下对EPC水乳状液进行改性。
