以丙烯酸、丙烯酸羟乙酯为功能单体，引入特殊材料A，并加入引发剂，采用溶液聚合法制备了一种新型低黏防静电丙烯酸酯压敏胶。着重探讨了特殊材料A用量和引发剂对压敏胶性能的影响。研究结果表明：当特殊材料A质量分数为15%时，压敏胶表面电阻值达到109Ω，防静电效果佳，且具有优良的初粘力和排气性；采用引发剂偶氮二异丁腈制备的压敏胶，具有更好的耐黄变性，当该引发剂质量分数为0.2%时，压敏胶转化率、黏度等综合性能较佳。
Abstract：A new low-viscosity antistatic acrylate pressure sensitive adhesive was prepared by solution polymerization with acrylic acid and hydroxyethyl acrylate as functional monomers,special material A introduced and initiator added. The effects of the amount of special material A and initiator on the properties of pressure sensitive adhesive were emphatically discussed. The research results showed that when the mass fraction of special material A was 15%,the surface resistance of pressure sensitive adhesive reached 109Ω,the antistatic effect was good,and it had excellent tack and exhaust performance. The yellowing resistance was better when the initiator azodiisobutyronitrile was used for the preparation of pressure sensitive adhesive. When the mass fraction of this initiator was 0.2%,the comprehensive properties of conversion rate and viscosity of pressure sensitive adhesive were relatively good.
