Reinforcing and toughening polylactic acid material and preparation method thereof

The invention provides a reinforcing and toughening polylactic acid material and a preparation method thereof, and relates to the field of polymer materials. The preparation method comprises the steps of mixing layered double hydroxides with epsilon-caprolactone and obtaining reactants, and after a ring opening polymerization, obtaining polycaprolactone modifier; conducting addition polymerization on the polycaprolactone modifier and diisocyanate, and obtaining prepolymer; making the prepolymer react with chain extender, and obtaining polyurethane modifier; melting and mixing the polyurethane modifier and polylactic acid, and obtaining the reinforcing and toughening polylactic acid material. Flexible chain segments of the polyurethane modifier improve the elasticity and flexibility of the material, rigid chain segments of the polyurethane modifier improve the strength and heat resistance of the material, and finally the overall mechanical property of the material is improved. Since the layered double hydroxides with a laminated structure are dispersed in a base material, the bending strength and stretching strength of the material are improved, and the anchoring effect of the material can avoid the modifier compatibility and migration problem which is easily generated from simple physical blending.

The invention discloses a method for improving the degreasing strength of an additive manufacturing formed ceramic part. The method comprises the following steps that polydimethylsiloxane is added into a ceramic powder material, and required raw material powder is obtained after even dispersing; the powder material and a liquid phase solvent are mixed, and ceramic slurry is prepared after even ball-milling; a ceramic part blank is formed through an additive manufacturing method, and after the blank is dried, degreasing and glue discharging are conducted; and in the degreasing heating process,the polydimethylsiloxane is softened and molten to permeate into adjacent ceramic particle gaps, and ceramic particles are wrapped. The polydimethylsiloxane is simple in molecular structure, low in carbon content and low in pyrolysis ignition lost rate, thus the wrapping bonding effect on the ceramic particles is small along with thermal attenuation of the temperature, the degreasing strength of the part can be established, and it is ensured that the blank has the sufficient strength margin to resist damage of gravity and thermal stress in a degreasing technology. The method can be used for improving the degreasing strength of the additive manufacturing ceramic part, and is especially suitable for additive manufacturing forming of ceramic parts of complex structures.
