Abstract

The invention discloses bioengineering plastic which is prepared from, by weight, 60-70 parts of fluorenone-chitosan polycondensate, 30-40 parts of polyhydroxyalkanoate PHA, 5-8 parts of biomass-basedgraphene and 1-3 parts of silane coupling agent KH560. A preparation method of the bioengineering plastic includes following steps: well mixing fluorenone-chitosan polycondensate, PHA, biomass-basedgraphene and the silane coupling agent KH560; adding the same into a double-screw extruder for extrusion molding to obtain the bioengineering plastic. The bioengineering plastic is high in strength and mechanical modulus, low in latent degeneration, high in wear resistance, excellent in fatigue resistance, chemical drug resistance, electricity resistance, flame resistance, weatherability, impact resistance, thermal resistance and size stability, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a bioengineering plastic and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy, the problems of environmental pollution, energy crisis, and resource shortage have become increasingly serious, and they have become the three mountains restricting social development. Making full use of renewable resources and reducing dependence on non-renewable fossil resources such as petroleum is of great significance to protecting the environment and promoting the sustainable development of the global economy. [0003] Engineering plastics refer to a class of high-performance polymer materials that can be used as structural materials, withstand mechanical stress in a wide temperature range, and be used in harsh chemical and physical environments. Because of its high strength, high mechanical modulus, low creep, strong w...
