Study on Properties of Polylactic Acid and Modified Calcium Carbonate Composite Materials

Abstract:

Based on the modified polylactic acid modified calcium carbonate, calcium carbonate in later polylactic acid blend will form a network structure in the composite material, effective to prevent the expansion of micro cracks, secondly, between the modified calcium carbonate will produce the corresponding yield, so that the modified calcium carbonate structure between plastic deformation, can impact absorbing energy, effective therefore, calcium carbonate particles exist, can effectively make the extension of small cracks in composite materials by passivation. Adding modified calcium carbonate composite materials, improve the crystallinity and composite heat resistance, but also reduces the cost of poly lactic acid and anti impact performance, its application field has been widely extended.
