<p>活性稀释剂是指各种具有不饱和度或官能团的单体，能聚合参与光固化反应，并对光固化齐聚体起稀释、调节黏度的作用，有利于涂布［17］。活性稀释剂可发生光固化反应，故减少了 UV 胶有机物质的挥发，具有良好的环保性能。</p> </div> </div> <h4>loctite PCB adhesive</h4> <p>活性稀释剂固化时具有收缩特性，很大程度上影响了 UV 胶的粘附力，且对皮肤有较大的刺激性。故减少其用量，解决光固化树脂的黏度问题成为研究重点［18］。Hult 等［19］用二羟甲基丙酸为活性稀释剂，合成了一定支化度的端羟基支化树脂; 再用烯丙基醚马来酸酐部分改性后成为一种热固化型支化聚酯。该合成物黏度低，减少了 UV 胶中活性稀释剂的用量，且其固化速率和固化膜的硬度随官能度的增加而提高，具有很好的性能。Kajtna 等［20］用丙烯酸－ 2 －乙基己酯和丙烯酸叔丁酯作为活性稀释剂，采用悬浮聚合法制得微球型 PSA; 加入 4 －丙烯酰氧基二苯甲酮后将其涂布在基材上，制得的UV 胶体积收缩率下降，但其粘接强度、剪切强度、剥离强度也受到影响。</p> </div> <div class="col-md-3 w3l_team_grid"> <div class="view view-second"> <img

<p>半导体封装领域，乐泰推出车规级与算力级双轨产品。车规级导电芯片粘接胶 ABLESTIK ABP 6392TEA，导热率 9.0 W/m-K，适配 QFP、QFN 封装的高可靠性 MCU，在裸铜、银及 PPF 引线框架上附着力优异，通过 MSL 1 高可靠性认证，配套新能源汽车半导体产线，2026 年预计实现销售额 3.8 亿元。针对 AI 算力芯片，毛细底部填充胶 Eccobond UF 9000AE 以低收缩、高韧性设计，防止大尺寸倒装芯片翘曲开裂，低热膨胀系数提升封装良率，成为 2.5D/3D 集成架构核心材料。</p> </div> </div> <h4>高折射率紫外固化胶</h4> <p>6 、操作时不应用力挤压和反复磨擦需粘接的材料，并建议使用固定工具；</p> </div> <div class="col-md-3 w3l_team_grid"> <div

1. 0% 时，胶粘剂的剥离强度相对较好; 以二苯甲酮衍生物米蚩酮作为引发剂时，相应胶粘剂具有良好的综合性能。阳离子光引发剂的优点在于紫外光照消失后仍可发生“后固化”而继续引发聚合，使光线不易到达的部位充分固化［26］。与自由基光引发剂相比，阳离子光引发剂具有收缩体积小、没有氧阻聚、可充分固化等独特优势［27］ ; 但其光固化速度很慢，品种少、价格高，受外界环境影响大。</p> </div> </div> <h4>电子无影胶</h4> <p>从应用场景来看，滤膜封装是净水领域的核心需求点。净水器中超滤膜、反渗透膜的封边与卷合，普遍采用双组份反应型聚氨酯胶粘剂，这类产品室温固化无副产物，耐温范围 - 40℃~120℃， Shore A 硬度 70-75，能在潮湿环境下实现无气泡密封，适配家用净水器、工业纯水设备的长期运行。此外，市政净水管道修复、商用净水设备模块化组装中，水处理胶需同时满足耐水压（0.3-0.6MPa）、抗氯腐蚀、无有害物质析出等要求，符合 NSF/ANSI 61 食品级认证成为市场准入关键。</p> </div> <div class="clearfix"> </div> </div> </div> </div>
