松香乳液和聚丙烯酸酯乳液共混 ,用共混液涂布成压敏胶带 ,考察了松香用量对压敏胶带粘合性能的影响.结果表明 ,随松香用量增加 ,180°剥离强度提高 ,并出现峰值 ;初粘力变化不大 ;持粘力下降.“,”Polyacrylate emulsion was blended with a rosin emulsion.The influence of the content of rosin on the adhesion properties of the polyacrylate was investigated.Results showed that the 180° peel strength increased and a peak value appeared,the ball tack property was not changed and the hold tack property decreased as the amount of rosin increased.
