Abstract

The invention relates to the technical field of preparation and modification of functional polymer materials, in particular to a method for preparing a cage-type organosilicon hybrid star-type polyester soft PVC plasticizer. The preparation method goes through: (1) ricinoleic acid undergoes cracking, oxidation, and hydrogenation reactions in sequence to obtain a mixed product of dihydric alcohol and nonanol acid; (2) octamethacryloyloxypropyl cage silsesquioxane Ester hydrolysis of the vertex group to obtain octapropanol-based cage silsesquioxane; (3) combining the mixed product obtained in step (1) with the octapropanol-based cage silsesquioxane obtained in step (2) Oxane, mixed with dimer acid according to the mass ratio to obtain a mixed solution; (4) Add an esterification reaction catalyst and a dehydrating agent to the mixed solution prepared in step (3), and reflux to obtain a cage-type organosilicon hybrid star Type polyester soft PVC plasticizer. The plasticizer has excellent application properties and improves properties such as migration resistance, solvent resistance effect, and weather resistance.

Description

technical field [0001] The invention relates to the technical field of preparation and modification of functional polymer materials, in particular to a method for preparing a cage-type organosilicon hybrid star-type polyester soft PVC plasticizer. Background technique [0002] Polyvinyl chloride (PVC) is one of the largest synthetic resin products in the world. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard and soft products. Among them, soft PVC products account for 30% of the PVC market share, and it is widely used in the manufacture of artificial leather, food packaging materials, wires and cables, and children's toys. The plasticizer used in soft PVC is mainly di(2-ethyl)hexyl phthalate (DEHP), which has good compatibility with PVC, high plasticizing efficiency, low price, and does not affect the safety of the product. It has many advantages such as sex and electrical insulation. However, since DEHP is a small molecu...
