The process of suspension polymerization was utilized to create acrylate resin microspheres with mesh numbers of 140-200 μm and particle sizes of 100 μm for implementation in mesh coating technology. The copolymer of methyl methacrylate (MMA) and methyl acrylate (MA) served as the primary polymer, with dibenzoyl peroxide (DBPO) functioning as the initiator, and a mixture of calcium carbonate and deionized water served as the dispersion medium. The surface morphology of the synthesized microspheres was analyzed through Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) to confirm successful synthesis. The optimal reaction conditions for the synthesis of these microspheres were determined to be a dispersant dosage of 30 g of calcium carbonate with a monomer ratio of 4:1, a reaction time of 1 h, an initiator dosage of 1.2 g of BPO, and a reaction temperature of approximately 75-80 C, resulting in microspheres with a regular spherical shape and smooth surface.
采用悬浮聚合法制备了目数为140 - 200μm、粒径为100μm的丙烯酸酯树脂微球，用于网涂技术。甲基丙烯酸甲酯（MMA）和丙烯酸甲酯（MA）的共聚物作为主要聚合物，过氧化二苯甲酰（DBPO）作为引发剂，碳酸钙和去离子水的混合物作为分散介质。通过傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）分析合成微球的表面形态，以确认合成成功。合成这些微球的最佳反应条件确定为：分散剂用量为30g碳酸钙，单体比例为4:1，反应时间为1h，引发剂用量为1.2g BPO，反应温度约为75 - 80℃，得到形状规则、表面光滑的微球。
