Abstract

The invention discloses a preparation method of a bamboo fiber-based degradable environmental protection material, comprising the following steps: step S1, weighing raw materials; step S2, drying the raw materials; step S3, weighing 6% polylactic acid and ethylene / acrylate / Glycidyl methacrylate terpolymer was banburyed for 40 minutes at 250°C and a rotational speed of 100r / min to obtain a pre-reactant; step S4, preparing pre-treated talcum powder; step S5, pre-reactant, remaining polylactic acid , Pretreatment talcum powder blending. The present invention adopts polylactic acid as matrix, and ethylene / acrylate / glycidyl methacrylate terpolymer toughens and modifies it; by modifying bamboo fiber first, not only the interface with PLA matrix can be increased Compatibility can also endow the material with good antibacterial properties; through the addition of talcum powder and coupling agent, it can play a reinforcing effect, further improve the mechanical properties of the material, and prepare a biodegradable and biodegradable material with excellent mechanical properties. Environmentally friendly material with antibacterial properties.

Description

Technical field[0001]The present invention belongs to the technical field of polymer materials, and in particular, to a method for preparing a bamboo fibromo-degradable environmental material.Background technique[0002]Bamboo contains a large amount of natural plant fibers, which has high strength and modulus, gradually leading the study of bamboo fibers to enhance fibers in composite materials. As a natural polymer reinforcing material, bamboo fiber has many advantages, such as cheap and easy, extensive source, low density, high tensile strength and modulus, small processing energy, and rehabilitability and ecological environment Compatibility, low environmental pollution and small harm to the human body. It is a new type of green environmentally friendly composite material with natural bamboo fiber, which is conducive to the environment and has huge economic potential.[0003]To this end, the development of bamboo fiber is not only a problem that the resources are resolved, but also ...
