Abstract

The invention provides a poly(3-hydroxybutyrate-3-hydroxyhexanoate)-carboxymethyl cellulose-straw powder composite full biodegradable material. The material is prepared by the following steps: mixingpoly(3-hydroxybutyrate-3-hydroxyhexanoate) (PHBHHx) and straw powder, adding a certain amount of carboxymethyl cellulose, phosphate coupling agent and polyoxyethylene, putting all the materials into athree-dimensional mixing machine for mixing, transferring the mixture into a mould, and putting the mould onto a plate vulcanizing machine for compression molding, so as to obtain a composite material. Compared with a poly(3-hydroxybutyrate-3-hydroxyhexanoate) product, a product prepared from the poly(3-hydroxybutyrate-3-hydroxyhexanoate)-plant fiber composite material has great advantages that the hydrophilicity of the material is improved, the mixing efficiency of the composite material is increased, and the processing property of the composite material can be obviously improved; the mechanical property and the mechanical property of the prepared product are greatly improved; the prepared composite material is high in tensile strength and strong in impact toughness, therefore, the composite material is a full degradable material with 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 poly(3-hydroxybutyrate-3-hydroxyhexanoate) carboxymethyl cellulose straw powder composite biodegradable material and its preparation method. Background technique [0002] The thermoplastic polyester polyhydroxyalkanoic acid (PHA) produced by microbial fermentation is a copolymer of polyhydroxybutyric acid PHB and polyhydroxyvaleric acid PHV, usually written as P(3HB-co-3HV). It is a kind of macromolecular polymer stored in the cells of microorganisms in a granular state under non-equilibrium growth conditions. Pure PHB is hard and brittle, with poor impact resistance and difficult to process and use. When PHA contains an appropriate amount of PHV, the hardness of the material decreases, the elasticity becomes better, and the processability is good. PHA is a real and completely degradable high-grade material, that is, it can be completely degraded into wate...
