摘要：选用两种商品化的丙烯酸酯热熔压敏胶,研究其不同涂布克重在不同紫外光照射能量、照射强度下的性能变化,及其与萜烯酚树脂共混改性的效果。研究结果表明,光照强度不变时,随着光照能量提高,丙烯酸酯热熔压敏胶凝胶率先上升后维持不变;低涂胶克重25 g/m^(2)时,丙烯酸酯热熔压敏胶初粘及剥离强度受光照能量的影响较大,受光照强度的影响较小;丙烯酸酯热熔压敏胶与不同牌号萜烯酚树脂共混改性后性能变化呈不同趋势,萜烯酚树脂含量10%的复配压敏胶初粘力及剥离强度上升,持粘时间下降。
Two kinds of commercial acrylic hot melt pressure-sensitive adhesives are selected to study their performance changes under different coating weights,different ultraviolet irradiation energy and different ultraviolet irradiation intensities,as well as their blending modification with different grades of terpene-phenolic resins.Research results show that as the ultraviolet irradiation intensity remains constant,the gelation rate of acrylic hot melt pressure-sensitive adhesives increases firstly and then remains unchanged with the increase of irradiation energy.As the coating weight is as low as 25 g/m^(2),the initial adhesion strength and peel strength of acrylic hot melt pressure-sensitive adhesives are greatly affected by the irradiation energy but less affected by the irradiation intensity.After acrylic hot melt pressure-sensitive adhesives are blended with different grades of terpene-phenolic resins,the performance of acrylic hot melt pressure-sensitive adhesives changes towards different trends.Composite acrylic hot melt pressure-sensitive adhesives containing 10%of terpene-phenolic resin have an increased initial adhesion power,an increased peeling strength and a decreased holding time.
