Abstract

The invention provides a polypropylene carbonate-carboxymethyl cellulose full degradable composite material. The composite material is prepared by the following steps: mixing polypropylene carbonate and straw powder, adding a certain amount of carboxymethyl cellulose, maleic anhydride and lignin fibers, putting all the materials into a three-dimensional mixing machine for mixing, transferring themixture into a mould, and putting the mould onto a plate vulcanizing machine for compression molding, so as to obtain the composite material. Compared with a polypropylene carbonate product, a productprepared from a polypropylene carbonate-plant fiber composite material has the great advantages that the production process is greatly lowered, and the bonding property of the mixed material is enhanced; the mechanical property of the product prepared by the invention is remarkably improved, and the product is high in hardness; as no coupling agent is added into the product prepared from the composite material, the product is safer and more environmentally friendly, and the cost of the full degradable material is greatly lowered, therefore, the composite material has good environmental protection value and economic value.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, specifically, a polypropylene carbonate carboxymethyl cellulose fully degradable composite material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a general term for polyesters corresponding to carbonic acid, and refers to a class of polymers containing (-OROC-)n in the main chain. With the difference of R in the formula, PC can be divided into aliphatic, fatty- Aromatic and aromatic polycarbonates. Among them, aromatic polycarbonate is widely used as one of the five major engineering plastics because of its excellent comprehensive performance. And with CO 2 In recent years, aliphatic polycarbonate (APC) prepared by non-phosgene method has been gradually developed into a new class of widely used materials. Its application in engineering plastics, elastomers, coatings, adhesives, oxygen barrier films and biodegradable materials has a...
