Abstract
The invention discloses green biodegradable composite plastic which contains a base material and a reinforcing material. The base material comprises the following materials, by weight, 40-50 parts of polystyrene, 20-25 parts of a degradation accelerator, 2-3.5 parts of an inorganic antibacterial agent, 1.5-3.5 parts of a plasticizer, 2-3.5 parts of an antioxidant, 1-2.5 parts of a dispersant and 2-4.5 parts of eleaostearic acid. The reinforcing material is natural bamboo fiber which accounts for 25 wt% of the weight of the green biodegradable composite plastic. Through the above mode, the invention provides the green biodegradable composite plastic, wherein the natural bamboo fiber has characteristics of high length-diameter ratio, high specific strength, large specific surface area, low density and low price. By combining the natural bamboo fiber with the base material of the biodegradable plastic, the composite material has characteristics of good processability, high strength, fast degradation speed, low manufacturing cost, low price and the like, and is also beneficial to environmental protection.
