Bamboo fiber-based degradable environment-friendly material and preparation method thereof

The invention relates to the technical field of bamboo fibers, in particular to a bamboo fiber-based degradable environment-friendly material and a preparation method thereof. Comprising the following raw materials in parts by mass: 30-40 parts of polylactic acid, 7-12 parts of poly (butylene succinate), 3-8 parts of bamboo fibers, 0.5-1 part of a coupling agent, 0.2-1 part of an epoxy oligomer, 0.1-0.3 part of a tertiary amine compound and 2-4 parts of a nano filler. The environment-friendly material is prepared by melting and blending the modified bamboo fibers, the degradable polylactic acid and the poly (butylene succinate), and the compatibility of interfaces among the materials is good, so that the prepared environment-friendly material has better tensile strength and larger elongation at break and is a very good degradable material. 本发明涉及竹纤维技术领域，具体一种竹纤维基可降解环保材料及其制备方法；包括以下质量份数的原料为聚乳酸30～40份、聚丁二酸丁二醇酯7～12份、竹纤维3～8份、偶联剂0.5～1份、环氧低聚物0.2～1份、叔胺化合物0.1～0.3份、纳米填料2～4份；使用改性后的竹纤维与可降解的聚乳酸、聚丁二酸丁二醇酯熔融共混，制备成环保材料，各材料间界面的相容
