影响胶带用聚丙烯酸酯压敏胶乳液性能的因素分析

Analysis on Influencing Factors of Properties of Polyacrylate Emulsion for Pressure-sensitive Adhesives Tapes

分析了影响聚丙烯酸酯压敏胶乳液产品性能的主要因素,并通过实验分析了反应温度、种子乳液量和阻聚剂量与产品性能之间的关系。结果表明:胶带用聚丙烯酸酯压敏胶乳液的反应温度在83～88℃,种子乳液量在10%时,乳液的初粘力、剥离力、持粘力达到平衡。

The main influencing factors of the properties of polyacrylate emulsion for pressure - sensitive adhesives tapes were analyzed and the effects of reaction temperature, the amount of seed emulsion and the dosage of polymerization inhibitor on the products properties were also discussed through the experimental research. It was found that the initial bonding strength, peel strength and endurance bonding strength of the adhesives could reach an optimal result when the reaction temperature was 83 - 88.℃ and the amount of seed emulsion was 10% in the preparation of pressure - sensitive emulsion adhesives.
