大豆蛋白基乒乓球拍底板热压工艺的研究

Study on hot-pressing technologies of soy protein-based table tennis bat

为了解决乒乓球拍释放有毒气体的问题,研究以改性大豆蛋白胶为胶粘剂,采用不同的热压工艺对乒乓球拍底板进行粘合,通过运动员试打评价及胶合强度检测,得到最佳的压板工艺:热预压90 min,热压压力1.4 MPa,热压温度150℃,热压时间10 min。

Different hot pressing technology parameters were investigated when preparing the table tennis bats using soy protein-based adhesive,in order to avoid harmful gas releasing from table tennis bats.The optimal performance of the bats was obtained by players＇evaluation and bonding strength as following：pre-heat pressure 90 min,hot pressing pressure 1.4 MPa,pressing temperature 150 ℃,pressing time 10 min.
