| 中文摘要: |
| 目的 采用生物质材料来改善丙烯酸酯压敏胶的粘接性能和耐热性能。方法 以松塔粉(EPC)作为改性剂，制备一种耐高温溶剂型丙烯酸酯压敏胶(aPSA)。详细讨论EPC用量对压敏胶初粘力、持粘力、180°剥离强度、玻璃化转变温度、热稳定和耐高温性能的影响。结果 EPC可有效改善压敏胶的内聚强度、粘接性能和耐热性能，当添加量为4%(相对于压敏胶干物质总质量而言)时，aPSA具有相对较好的综合性能，与未添加EPC体系相比，持粘力和180°剥离强度分别提高了120.0%和46.2%，玻璃化转变温度和质量损失10%时的温度分别提高了11 ℃和40 ℃。结论 该压敏胶可在140 ℃高温下使用，同时也扩大了EPC应用范围。 |

| The work aims to improve the adhesion and heat resistance of acrylate pressure sensitive adhesive (aPSA) with a novel biomass material. A kind of aPSA was prepared with pinecone powder (EPC) as modifier. The effects of EPC content on the initial tack, holding power, 180° peel strength, glass transition temperature (Tg), thermal stability and high temperature resistance of aPSA were discussed in detail. Results showed that the EPC could effectively improve the cohesion strength, adhesive and heat resistant performance of pressure sensitive adhesive. When the EPC amount of 4% (relative to the total mass of dry matter of pressure sensitive adhesive) was used, aPSA had a relatively good comprehensive performance, and its holding power and 180° peel strength increased by 120.0% and 46.2%, respectively, compared with the unmodified system. In addition, the 10% mass decomposition temperature and Tg increased by 11 ℃ and 40 ℃, respectively. In brief, the prepared aPSA can be used at 140 ℃, and this method can be used to extend the application of EPC. |
