Problems solved by technology

However, with the deepening of research, the shortcomings of this type of plasticizer are gradually exposed. The longer alkyl chain structure makes the plasticizer more volatile and unstable in thermodynamic properties, resulting in products that are not resistant to migration. After use, the surface of the product is easy to soften, sticky or even cracked, which greatly reduces the use effect of the product
At the same time, the migration resistance is usually related to the pollution resistance, and the products with poor migration are usually not resistant to pollution, which will also reduce the use effect of the products

Abstract

The invention discloses a plasticizer containing multiple rigid cyclic structures as well as a preparation method and application thereof, and belongs to the technical field of auxiliaries for plastic. The preparation method comprises the following steps of subjecting one of resorcinol dihydroxyethyl ether or hydroquinol dihydroxyethyl ether and a monobasic acid containing a rigid structure to an esterification reaction under the catalytic action of a catalyst and under a high vacuum degree, preparing to obtain a plasticizer crude product, also preparing to obtain a plasticizer pure substance through later purification treatment, subjecting the plasticizer pure substance to structural characterization respectively through a nuclear magnetic resonance hydrogen spectrum, a mass spectrum and an infrared light spectrum. The plasticizer containing the multiple rigid cyclic structures, which is prepared by the preparation method, is mainly applied to PVC (Polyvinyl Chloride) resin; the plasticizer containing the multiple rigid cyclic structures, which is prepared by the preparation method, is used for not only effectively improving the heat stability and the transference resistance of the plasticizer but also quite well improving the antistatic property of a PVC product; the serviceable range of the PVC product is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of plastic additives, in particular to a plasticizer containing multiple rigid ring structures, a preparation method and an application thereof. Background technique [0002] A plasticizer is a substance added to plastics, resins or elastomers to improve their processability, plasticity, flexibility, and stretchability, but does not change the basic chemical properties of the plasticized material. It is mainly used in polyvinyl chloride (PVC) resin, and the amount used in PVC can account for more than 98% of the entire plasticizer amount. Therefore, the development of plasticizers is closely related to the development of the PVC industry. At present, the types of plasticizers commonly used in China mainly include phthalates, terephthalates, alkylsulfonate phenyl esters, fatty acid esters, etc., and their output accounts for about 80% of the total plasticizers. In recent years, with the rapid development of ...
