Abstract

The invention relates to the technical field of environment degradable composite materials, in particular to a preparation method of a biodegradable composite material. The preparation method comprises the following steps: cleaning plant fiber raw materials, drying, pulverizing, soaking in warm alkali liquor, filtering, washing until the washing liquor is neutral, and drying to obtain pretreated plant fiber; adding an episulfide silane coupling agent and a fluorosilane coupling agent into the ethanol solution of the pretreated plant fibers, and carrying out a heating reflux reaction to obtainmodified plant fibers; preparing methylbenzene dispersion liquid of the modified plant fibers, adding lactide and a catalyst, and reacting to obtain the biodegradable composite material. According tothe preparation method of the biodegradable composite material, agricultural waste is used as a raw material, the cost is low, the biodegradable composite material can be naturally and completely biodegraded after being used, environmental pollution cannot be caused, and the composite material has an excellent antibacterial effect and weather resistance after being optimized and modified.

Description

technical field

[0001] The invention relates to the technical field of environmentally degradable composite materials, in particular to a preparation method of biodegradable composite materials. Background technique

[0002] With the modernization and development of industry, while enriching people's life, great material resources have produced such as construction waste, electronic product waste, chemical waste and white pollution in the usual sense. Among the above waste, metals such as copper, iron, zinc and aluminum Except for a few items such as paper and paper that can be recycled, most of the rest of the garbage and waste are disposed of by landfill, incineration, etc. In the process of disposal, some resources are inevitably wasted and pollution of water sources and air is generated. Among them, plastic packaging materials, which account for a huge proportion, are especially polluting to the environment. Their incineration has huge environmental pollution, while land...
