Problems solved by technology

The flame retardant effect of halogen or phosphorus is obvious, but it is also relatively harmful to the environment. For example, dioxins are produced when halogen-containing flame retardant materials are burned, which can exist in the environment for many years, and even accumulate in organisms for life; phosphorus will cause water quality deterioration. Eutrophication, serious water pollution

Abstract

The invention relates to a non-phosphorus and non-halogen flame-retardance polyester sheet material. The material comprises a polyester base material and a flame-retardance coating which coats the surface of the polyester base material. The material is characterized in that the flame-retardance coating comprises, by weight, 11-25% of non-phosphorus and non-halogen flame retardant and 74.5-88% of polyacrylate. The non-phosphorus and non-halogen flame retardant is composed of sodium polyacrylate and poly propylene carbonate. Sodium polyacrylate is of a network molecular structure and can achievethe moisture absorption and moisture preservation effects, the temperature of the surrounding environment of the polyester sheet material is lowered to a certain extent, the humidity is increased, and the flame retardance of the polyester sheet material is improved; propylene carbonate can be heated and decomposed to generate a large amount of carbon dioxide under the burning condition, the oxygen concentration in the surrounding environment of the polyester sheet material is lowered, and the flame retardance aim is achieved. The flame retardant does not contain halogen or phosphorus, and theproblem of environmental pollution is solved. Meanwhile, a surface coating method is adopted, the preparation technology is easier and more convenient to use, and the method helps to improve the working efficiency and lower the production cost.

Description

technical field [0001] The invention relates to the field of polyester sheets, in particular to a phosphorus-free and halogen-free flame-retardant polyester sheet 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. Compared with ordinary sheets, polyester sheets have better mechanical properties. 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 instruments, electrical components; audio tapes, video tapes, film films, computer floppy disks, metal...
