Abstract

The invention provides a poly-(3-hydroxybutyrate-3-hydroxyhexanoate)corn fiber glue plant fiber fully-degraded composite material which is prepared by the following steps: mixing poly-(3-hydroxybutyrate-3-hydroxyhexanoate)(PHBHHx) with straw powder, and adding a certain amount of corn fiber glue and polyethylene glycol; putting all materials in a three-dimensional mixing machine so as to be mixed;transferring the mixture into a mold; and putting the mold on a plate vulcanizing machine so as to be subjected to compression molding, thereby obtaining the composite material. Compared with a PHBHHx product, a product prepared from the PHBHHx plant fiber composite material has great advantages that the hydrophilicity is improved, the material mixing difficulty is greatly reduced, the adhesion property of the mixed material is enhanced, the dynamical strength and the mechanical strength of the product are obviously improved, and the tensile strength and the elongation at break are enhanced;the product prepared from the composite material provided by the invention has high toughness and high heat resisting temperature; no coupling agent is added, so that the composite material is safe and nontoxic, and the cost of the fully-degraded material is greatly lowered; and the composite material has good environmental protection value and economic value.

Description

technical field [0001] The present invention relates to a composite material and a preparation method thereof, specifically, a poly(3-hydroxybutyrate-3-hydroxyhexanoate) corn viscose plant fiber fully degradable composite material and a preparation method thereof . Background technique [0002] Polyhydroxyalkanoates (PHA for short) are prokaryotic microorganisms that store excess carbon sources in the form of carbon sources and energy when they are limited by the supply of certain basic nutrients (such as N, P, S, O or Mg). A class of synthetic intracellular thermoplastic polyesters can account for 30% to 80% of the dry weight of cells. PHA has mechanical properties similar to traditional plastics such as polypropylene (PP) and polyethylene (PE), and can be completely degraded in nature, so it has a good application prospect. However, the relatively high glass transition temperature and melting point of PHA, poor stability, easy degradation, especially its high production ...
