| 中文摘要: |
| 橡胶型压敏胶（RPSAs）广泛应用于胶带、标签等领域，其粘合性能评价标准有初粘性、剥离强度和持粘性3项。用作RPSAs基体的橡胶弹性体主要有天然橡胶（NR）、合成橡胶（SR）和热塑性弹性体（TPE）3类，新型TPE基RPSAs为近年来的研究热点。对于RPSAs的优化主要从基体改性和优化配方两个方面展开，基体改性采用物理和化学改性手段，配方优化包括调整增粘树脂品种和用量等。与其他种类的压敏胶相比，橡胶型压敏胶具有独特优势，应用领域越来越广。 |
| 英文摘要: |
| Rubber-based pressure sensitive adhesives（RPSAs） are widely used in the fields of tape and label, and their adhesive properties can be evaluated in terms of initial adhesion，peel strength and shear adhesion strength. The rubber elastomers used for the matrix of the RPSAs include natural rubber（NR），synthetic rubber（SR） and thermoplastic elastomer（TPE），and TPE has attracted great attention in recent years. The optimization of RPSAs is mainly carried out from two aspects：modification of the matrix and optimization of formulation. Matrix modification includes physical and chemical methods，and formulation optimization includes adjusting the type and additional level of tackifying resin. Compared with other types of the PSAs，RPSAs have unique advantages，and their application will be more and more
widespread. |
