 摘 要：
 隨著塑料工業的迅速發展，發泡塑料以其良好的緩沖性能和相對低廉的價格在運輸包裝中被廣泛使用。但同時也制造出大量難以處理的塑料廢棄物，給環境帶來嚴重危害。許多國家都已開始使用紙漿模塑材料代替聚苯乙烯類發泡塑料作緩沖材料。但紙漿模塑材料的緩沖性能有限，不能滿足大型包裝件的要求。環保的發泡緩沖材料已成為國內外的研究熱點，但目前國內尚未出現相關成熟的產品。所以本課題的研究具有十分重要的研究和應用價值。
 本課題結合了紙漿模塑制品和發泡塑料的制造、成型的工藝，在實驗和理論相結合的基礎上，對紙漿的發泡技術進行深入研究。研究的主要內容有：紙漿的發泡技術機理；實驗配方的確定；黏結劑、發泡劑對紙漿發泡材料的性能的影響。根據正交實驗得到的最佳實驗配方如下：紙漿：30g、玉米淀粉：15g、復合粘結劑（PVA、CMC）：3g、復合發泡劑（碳酸氫鈉、碳酸氫銨、碳酸鈉）：3g和助劑：2g（增塑劑：1g，成核劑：1g）。發泡溫度：120℃。所得的紙漿發泡緩沖材料表觀性能良好，有彈性，表明紙漿發泡緩沖材料具有一定的緩沖性能。
 通過本課題的研究，證明了紙漿發泡的可行性，為早日開發出成熟的植物纖維緩沖發泡材料奠定了一定的理論基礎，具有參考和應用價值。

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.
