一种用于电子级保护膜的丙烯酸接枝纳米材料水性压敏胶
摘要：
本发明提供了一种用于电子级保护膜的丙烯酸接枝纳米材料水性压敏胶。以该压敏胶的总重量计，其具有以下原料组成：丙烯酸丁酯、丙烯酸异辛酯、甲基丙烯酸甲酯和丙烯酸、43-44wt％，溶剂、53-55wt％，引发剂、0.6-1.0wt％，水性纳米ZnO、0.5-1.0wt％，流平剂、0.05-0.06wt％，消泡剂、0.05-0.07wt％，中和剂、0.5-0.8wt％，缓冲剂、0.07-0.1wt％，非离子乳化剂BL-225、0.03-0.1wt％，阴离子乳化剂H95、0.47-0.9wt％；各原料组成之和满足100％。该压敏胶具有初粘性好、持粘性久、剥离强度高等特点，弥补了本行业中所采用的油性丙烯酸胶的缺陷，是既环保又安全的绿色产品。
摘要（英）：

The invention provides a crylic acid grafted nano material aqueous pressure-sensitive adhesive for an electronic-grade protective film. Based on the total weight of the pressure-sensitive adhesive, the pressure-sensitive adhesive comprises the following raw materials: 43-44wt% of butyl acrylate, iso-octyl acrylate, methyl methacrylate and crylic acid, 53-55wt% of solvent, 0.6-1.0wt% of initiator,0.5-1.0wt% of aqueous nano ZnO, 0.05-0.06wt% of flatting agent, 0.05-0.07wt% of defoamer, 0.5-0.8wt% of neutralizer, 0.07-0.1wt% of buffer, 0.03-0.1wt% of nonionic emulsifier BL-225 and 0.47-0.9wt% of anionic emulsifier H95, wherein the sum of all raw material components is 100%. The pressure-sensitive adhesive has the characteristics of good initial adhesiveness, durable persistent adhesiveness,high peel strength and the like, makes up the defects of oily crylic acid adhesive used in the industry, and is a environmentally-friendly and safe green product.
