epoxidized soybean oil

Polylactide composite materials with organic filler-modifier starch, inorganic filler -calcium carbonate and plasticizer - epoxidized soybean oil for 3D printing have been developed. On the basis of the modular deformation method of calculation the elastic-plastic and deformation properties of the developed modified polylactide materials are determined. The change of modulus of deformation, modulus of elasticity, modulus of high elasticity depending on the composition of the composite is revealed.

The physicochemical regularities of interactions in the starch-glycerol-epoxidized soybean oil system under the influence of ultrasound were investigated. On the basis of rheological curves, the effect of plasticizers on the viscosity of glycerin-starch systems was revealed, depending on the shear rate, time of exposure at temperature, and the nature of starch. On the basis of IR spectroscopic studies, the existence of interactions between the components of the system was confirmed.

The effect of epoxidized soybean oil on the viscosity of glycerin-moist starch systems was revealed. On the basis of IR spectroscopic studies and refractive index values, the existence of interactions between the system components was confirmed.

Розроблено полілактидні композиційні матеріали з неорганічним наповнювачем -кальцію карбонатом які модифіковані епоксидованою соєвою олією та гліцерином. На підставі модульно-деформаційного методу розрахунку визначено пружно-пластичні властивості розроблених полілактидних матеріалів і коефіцієнт структури. Виявлено зміну модуля деформації, модуля пружності, поверхневої твердості, теплостійкості за Віка і термомеханічних характеристик полілактидних композитів.
