Abstract

The invention discloses an ecotype environmental protection material and a preparation method thereof. According to the ecotype environmental protection material and the preparation method thereof, provided by the invention, aiming at the poor combination of plant fibers and plastic, a biological fermentation method is fully utilized to treat melon, fruit, vegetable fibers, then low-density polyethylene (LDPE) is taken as a main composite material, a reasonable formula is set, the methods and principles of biology, chemistry and physics are combined, and proper processing steps and parameters are adopted, so as to obtain a high-performance bio-composite material by squeezing granulation through a screw rod. The material can be processed to form various products through the ways of injection molding, extrusion, mould pressing, machining and the like, is widely used in the fields of packaging, electronics, communication, furniture, decoration, automobiles, airplanes, war industry and the like, is capable of replacing the materials of plastic, logs and the like, and has very good social benefit and economic benefit.

Description

technical field [0001] The invention relates to an ecological environment-friendly material, in particular to a biomass composite material produced by a biochemical method and a preparation method thereof, which can be used to replace plastics, wood and other fields. Background technique [0002] At present, the materials used in the fields of packaging, electronic appliances, home decoration, automobiles, aircrafts, and military industries are mainly petroleum-based plastics, and some logs are used. However, plastics have the disadvantages of being non-biodegradable and polluting the environment. At the same time, the oil resources are limited and not sustainable. The use of a large number of logs will cut down a large number of forests and destroy the ecological environment. Therefore, by combining waste plant fibers with some polymer plastics, a higher-performance wood-plastic composite material can be produced, which can replace wood and plastic, and alleviate resource ...
