Abstract

The invention relates to a temperature-resistant PET (polyethylene terephthalate) sheet containing sodium polyacrylate. The PET sheet comprises a PET substrate and a coating which coats the surface ofthe PET substrate and contains sodium polyacrylate. The PET sheet is characterized in that the coating contains 6%-20% (in percentage by weight) of sodium polyacrylate and 79.5%-93% (in percentage byweight) of polyacrylate. Sodium polyacrylate has a network molecular structure and can well play moisture absorption and moisturizing roles, so that the temperature of the environment around the PETsheet is reduced to a certain extent, the humidity is increased, the high-temperature resistance of the PET sheet is improved, and the use range of the PET sheet is expanded. Meanwhile, the preparation technology is simpler and more convenient due to adoption of a surface coating method, the working efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of polyester sheets, in particular to a temperature-resistant polyester sheet containing sodium polyacrylate and a preparation method thereof. Background technique [0002] Polyester sheet (PET) uses polyethylene terephthalate as the main raw material and is a material with relatively comprehensive properties. It has good transparency and high gloss; it has good air tightness and fragrance retention. Compared with ordinary sheets, polyester sheets have better mechanical properties, better tensile strength and impact strength. Polyester sheet also has excellent electrical insulation properties, weak acid resistance and oil resistance, and also has the advantages of non-toxicity, good stability against chemicals, and low water absorption. Polyester sheet is used as various food, medicine, non-toxic and sterile packaging materials because of its many advantages; high-grade packaging materials for textiles, precision in...
