Abstract

A poly(3-hydroxybutyrate-3-hydroxyhexanoate) gum arabic straw powder composite biodegradable material, which is made of poly(3-hydroxybutyrate-3-hydroxyhexanoate) (PHBHHx) Mix it with straw powder, add a certain amount of gum arabic, lignin, and polyethylene oxide, put all the materials in a three-dimensional mixer and mix them, then move the mixture into a mold, place it on a flat vulcanizer, and mold it to form a composite material . The products made by poly(3-hydroxybutyrate-3-hydroxyhexanoate) plant fiber composite materials of the present invention have much better properties than poly(3-hydroxybutyrate-3-hydroxyhexanoate) products Big advantages: mainly include improving the hydrophilicity of the material, increasing the mixing efficiency of the composite material, and significantly improving the processing performance of the composite material; the products made by the present invention have high tensile strength and greatly improved mechanical properties; The prepared composite material has high heat-resistant temperature, greatly reduces the cost of fully degradable materials, and 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 poly(3-hydroxybutyrate-3-hydroxyhexanoate) gum arabic straw powder composite biodegradable material and its preparation method. Background technique [0002] Polyhydroxyalkanoate (PHA) is a type of polyester that can be synthesized in the cytoplasm by many microorganisms as a carbon source and energy storage material under the condition of sufficient carbon source and lack of other nutrients (such as sulfur, phosphorus, nitrogen, etc.). Because it is completely biodegradable, it is a new type of biomaterial that can replace traditional plastics. The biosynthetic pathways of such polyesters in different microbial cells have been extensively and deeply studied. In order to reduce its production cost and realize industrial production, screening for higher-yielding strains and using cheap carbon sources to synthesize PHA have become the research focus in recen...
