Degradable natural fiber composite material and preparation method thereof

The invention discloses a degradable natural fiber composite material and a preparation method thereof, and belongs to the technical field of natural fiber composite materials. Comprising the following raw materials in parts by weight: 20-40 parts of natural fibers, 100-120 parts of carboxyl functionalized polylactic acid, 6-12 parts of an auxiliary agent, 1-5 parts of a nucleating agent and 4-8 parts of a lubricant. According to the prepared composite material, polylactic acid is used as a matrix, natural fibers are used as a reinforcing material, the crystallization rate of polylactic acid is increased, and the composite material is endowed with excellent degradability and mechanical properties; wherein the additive can greatly improve the interfacial compatibility of the polylactic acid and the natural fiber, and also can enhance the flexibility and flame retardance of the composite material, so that no additional flame retardant is needed to influence the homogeneity of the material, and the performance o
