Abstract

The invention relates to the field of high polymer materials, and especially relates to a plasticizer, and a preparation method and application thereof. The application is application of a compound as shown in a formula (I) as the plasticizer. In the formula, R1 or R2 is selected from any one of alkyl, polyethylene glycol or methoxy polyethylene glycol. The invention provides construction of a novel thiazolidinone-based bio-based plasticizer for the first time. The pyridone diacid has the advantages of renewable raw materials, simple synthesis, low biotoxicity and the like, and can effectively reduce the production cost of the plasticizer, the environmental pressure and the safety risk in the use process, so that the bio-based plasticizer disclosed by the invention is expected to replace the traditional phthalate plasticizer.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a plasticizer and its preparation method and application. Background technique [0002] Plasticizers are a class of polymer additives that are added to polymer materials to increase the plasticity of polymers. The use of plasticizers can improve the performance of polymer materials, reduce production costs and increase production efficiency. [0003] At present, the commonly used plasticizers are phthalates, represented by di-isooctyl phthalate (DOP), with an annual consumption of up to 4 million tons. However, phthalate plasticizers have high biological toxicity, and their inevitable leaching and migration during processing and practical application have brought huge safety risks to the human body and the ecological environment. Currently, the production and use of phthalate plasticizers are under scrutiny by regulators around the world. [0004] The production of phthalate p...
