Abstract

The invention relates to a biodegradable rice hull powder based composite comprising the following components in parts by weight: 500 parts of rice hull powder, 20-30 parts of glass fiber, 4-6 parts of nano-montmorillonite, 4-6 parts of surface modifier, 4-6 parts of antioxidant, 110-130 parts of polylactic acid, 8-12 parts of thermoplastic resin, 10-15 parts of titanium dioxide and 10-12 parts oflubricant. The biodegradable rice hull powder based composite adopts clean and dry rice hull powder as a matrix so as to have the characteristic that the raw materials are regenerative, green and environment-friendly; due to the addition of the one-dimensional glass fiber, the two-dimensional lamellar nano-montmorillonite and the three-dimensional nanometer titanium dioxide, the rigidity and strength of the material are guaranteed; and due to the adoption of the thermoplastic resin, the toughness is enhanced.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a biodegradable rice husk powder-based composite material and a preparation method thereof. Background technique [0002] my country is a large agricultural country, among which the rice planting area is the largest in the world. According to incomplete statistics, my country's annual output of rice husks reaches 80 million tons, which are currently mainly used for power generation, preparation of white carbon black and activated carbon, brewing and chemical raw materials, etc., but only a small proportion of them are economically and efficiently utilized. A large amount of rice husks have to be buried or incinerated due to the large area, resulting in serious waste of resources and environmental pollution. [0003] As a biomass material, rice husk has biodegradable properties. At present, the research on using its biodegradable properties mainly uses rice husk powder as a fille...
