Abstract

The invention belongs to the technical field of plastic additives, in particular to a trimesic acid synthetic ester plasticizer with excellent high and low temperature resistance, and further discloses its synthesis method and its application in the field of plastic processing. Trimellitic acid synthetic ester plasticizer described in the present invention, take trimesic acid, pinacol, isooctyl alcohol, 2-ethyl glycolate and 2-perfluorooctyl alcohol and xylene as raw materials, in Under the premise of ensuring the excellent plasticizing performance of the product; the low temperature resistance and high temperature resistance of the product are effectively improved, so that the high temperature resistance can reach 160°C. Compared with the existing phthalate plasticizers, the present invention The plasticizer product has a relatively large molecular structure, which effectively ensures the low extraction resistance of the product and has the advantage of being more stable.

Description

technical field [0001] The invention belongs to the technical field of plastic additives, in particular to a trimesic acid synthetic ester plasticizer with excellent high and low temperature resistance, and further discloses its synthesis method and its application in the field of plastic processing. Background technique [0002] Plasticizer, also known as plasticizer in general, is a polymer material additive widely used in industry, and it is also the largest additive variety in the modern plastics industry. Adding it to the resin in a certain proportion can change the properties of the resin, such as increasing the flexibility of the plastic, improving the temperature resistance, improving the usability of plastic products at low temperatures, reducing the viscosity of the molten material, and making the resin easy to process and shape, etc. , especially plays a decisive role in promoting the development of the plastics industry, especially the polyvinyl chloride industry...
