Problems solved by technology

However, the production process of CPE will produce a large amount of acid-containing wastewater, and the post-treatment of such wastewater has always been the most difficult problem faced by related companies
Therefore, although the production process of CPE is relatively simple, the energy consumption of the obtained product is high, the pollution is serious, and it is not sustainable.

Abstract

The invention discloses a method for preparing a plant oil-based core-shell structural flexibilizer. The method is characterized in that liquid plant oil serves as a core, and the core is adopted to properly crosslink so as to obtain a relatively stable plant oil core structure; and then, a layer of hard polymer shell with high fluidity and solubility parameters similar to polyvinyl chloride (PVC) is polymerized on the external surface of the plant oil core structure through grafting free radical polymerization. The plant oil-based core-shell structural flexibilizer which is suitable for PVC is obtained through designing different core-shell structures. Compared with a conventional flexibilizer (such as acrylate copolymer ACR and chlorinated ppolyethylene CPE), the plant oil-based core-shell structural flexibilizer has the advantages of low price, high toughening efficiency, green, environment friendliness and the like; and the plant oil-based core-shell structural flexibilizer can be widely applied to the fields such as PVC building door and window sections, pipes, pipe fitting, electric wires and cables, conduits, small household appliances and the like.

Description

technical field [0001] The invention relates to a preparation method of a vegetable oil-based toughening agent with a core-shell structure, belonging to the field of preparation and modification of functional polymer materials. Background technique [0002] Polyvinyl chloride (PVC) is one of the four general-purpose polymer materials, and it is also a rare non-petroleum-based polymer material among many polymers. Because PVC is mainly produced by the calcium carbide method, it hardly depends on petroleum resources. Its excellent mechanical properties, self-extinguishing properties and relatively low price have made it widely used in toys, footwear, construction, decoration, agriculture and other fields. At present, the global production of PVC has exceeded 40 million tons per year. Among them, more than 50% are used in the manufacture of PVC building materials, which means that the annual usage of PVC tougheners will exceed 1.5 million tons. [0003] ACR is currently the ...
