摘要
聚乙烯纤维的轻质高强度、耐磨耐久性、抗冲击性、耐化学腐蚀性、绿色环保性,可赋予纸轻质高强、耐磨、耐用、环境稳定、环保安全等多重优势特性。因此,以聚乙烯纤维纸为原料,通过湿法抄造工艺结合浸渍热压工艺,生成综合性能优异的高强纸基材料,对体育用品、航空航天等多领域具有战略性意义。通过详细分析聚乙烯纤维、纸基材料性能,及聚乙烯纤维纸基材料制备工艺流程,改性制备了聚乙烯纤维高强纸基材料,并对其强度进行了测试分析。结果表明,当聚乙烯纤维用量为70 g、阔叶木浆用量为30 g、阔叶木浆打浆度为60°SR时,聚乙烯纤维原纸强度表现最佳;当热压时间为15 min、热压压力为10 MPa、热压温度为130℃时,聚乙烯纤维纸基材料强度表现最佳。
The lightweight,high-strength,wear-resistant,durable,impact resistant,chemical corrosion resistant,and environmentally friendly properties of polyethylene fiber can endow paper with multiple advantages such as lightweight,high strength,wear resistance,durability,environmental stability,and environmental safety.Therefore,using polyethylene fiber paper as raw material and combining wet papermaking process with impregnation and hot pressing process to generate high-strength paper-based materials with excellent comprehensive performance has strategic significance for sports goods,aerospace and other fields.By analyzing in detail the properties of polyethylene fibers and paper-based materials,as well as the preparation process of polyethylene fiber paper-based materials,high-strength polyethylene fiber paper-based materials were modified and tested for their strength.The results show that when the amount of polyethylene fiber is 70 g,the amount of broad-leaved wood pulp is 30 g,and the beating degree of broad-leaved wood pulp is 60°SR,the strength performance of polyethylene fiber base paper was the best;when the hot pressing time is 15 minutes,the hot pressing pressure is 10 MPa,and the hot pressing temperature is 130℃,the strength performance of polyethylene fiber paper-based material is optimal.
