Abstract

The invention relates to the technical fields of the preparation and modification of functional macro-molecular materials, and particularly relates to a preparation method of a cage-shaped organic silicon hybridized star-shaped polyester soft PVC plasticizer. The preparation method comprises the following steps: (1) sequentially cracking oxidizing and hydrogenating ricinoleic acid to obtain a mixed product of dihydric alcohol and nonanol acid; (2) facilitating esterolysis reaction of an apex group of 8-methacryloxypropyl cage-shaped silsesquioxane to obtain 8-propanol cage-shaped silsesquioxane; (3) mixing the mixed product obtained in the step (1) and the 8-methacryloxypropyl cage-shaped silsesquioxane obtained in the step (2) with a dimer acid according to a mass ratio to obtain a mixed solution; and (4) adding an esterification catalyst and a dehydration agent into the mixed solution prepared in the step (3), and refluxing to obtain the cage-shaped organic silicon hybridized star-shaped polyester soft PVC plasticizer. The plasticizer has excellent application performance and is high in migration resistance, solvent resistant effect, weather resistance and the like.

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...
