 摘 要：
 随着塑料工业的迅速发展，发泡塑料以其良好的缓冲性能和相对低廉的价格在运输包装中被广泛使用。但同时也制造出大量难以处理的塑料废弃物，给环境带来严重危害。许多国家都已开始使用纸浆模塑材料代替聚苯乙烯类发泡塑料作缓冲材料。但纸浆模塑材料的缓冲性能有限，不能满足大型包装件的要求。环保的发泡缓冲材料已成为国内外的研究热点，但目前国内尚未出现相关成熟的产品。所以本课题的研究具有十分重要的研究和应用价值。
 本课题结合了纸浆模塑制品和发泡塑料的制造、成型的工艺，在实验和理论相结合的基础上，对纸浆的发泡技术进行深入研究。研究的主要内容有：纸浆的发泡技术机理；实验配方的确定；黏结剂、发泡剂对纸浆发泡材料的性能的影响。根据正交实验得到的最佳实验配方如下：纸浆：30g、玉米淀粉：15g、复合粘结剂（PVA、CMC）：3g、复合发泡剂（碳酸氢钠、碳酸氢铵、碳酸钠）：3g和助剂：2g（增塑剂：1g，成核剂：1g）。发泡温度：120℃。所得的纸浆发泡缓冲材料表观性能良好，有弹性，表明纸浆发泡缓冲材料具有一定的缓冲性能。
 通过本课题的研究，证明了纸浆发泡的可行性，为早日开发出成熟的植物纤维缓冲发泡材料奠定了一定的理论基础，具有参考和应用价值。

Plant fiber foam cushioning materials
 Abstract:
 With the rapid development of the plastic industry,the expanded plastic has been usedwidely in packing for transport for its good cushion performance and proper price.But it hasbrought a great deal of plastic waste which can not be difficultly efficiently disposed.The wastehas brought serious damage to the environment.Many countries have replaced molded pulpproduct to expanded plastic such as PS buffer material.However,the cushion performance ofmolded pulp product can’t meet the need of huge package.The green expanded product hasbecome a study hotspot all over the world.The mature foaming pulp material has not appearedin our country yet.
 The study has very important research and application value.The study combines the technics of the expanded plastic and molded pulp.On the basis ofexperiment and theory combination,we have deeply studied the foaming technology of pulp.The research mainly includes that the foaming principle and technics of pulp;The decision ofexperiment prescription and the infection of adhesive blowing agent for the characterof foaming pulp material and the cushion performance and comparison of foaming pulpmaterial.According to the orthogonal experiment,we get optimal experiment prescription thatis:pulp:30g, Corn starch:15g, composite binder(PVA、CMC):3g, mixed blowing agent(sodium bicarbonate, Ammonium bicarbonate, Sodium carbonate:3g,assist-antagent:2.0g,plasticizer:1.0g,nucleate:1.0g,foaming temperature:120℃. Pulp from the foam cushioning material apparent good performance, flexible foam cushioning materials show that the pulp has a certain buffer performance.
 The study has proved the foaming feasibility of pulp and established definite base fordeveloping the mature foaming molded pulp material.The study has stated value of referenceand application.
