Abstract

The invention relates to a flame retardant and environment-friendly PET heat-shrinkable material and a method for preparing the same. The flame retardant and environment-friendly PET heat-shrinkable material comprises 40 to 60 percent of PETP, 15 to 30 percent of PETG, 5 to 8 percent of poly terephthalic acid succinimide ester, 1 to 2 percent of thermoplastic elastomers, 10 to 20 percent of phosphate flame retardant and 0.01 to 0.05 percent of lubricant. The method comprises the following steps: 1, pre-drying raw materials; 2, blending the materials and pelletizing; 3, blending material and drying; and 4, extruding to mold. The method is simple in technology, the flame retardant and environment-friendly PET heat-shrinkable material has better fireproof flame retardant property than the prior PET heat-shrinkable material, and all the environmental standards are higher than the prior PET heat-shrinkable material.

Description

technical field [0001] The technical solution of the invention relates to a heat-shrinkable material and a preparation method thereof, in particular to a flame-retardant and environment-friendly PET heat-shrinkable material and a preparation method thereof. Background technique [0002] Environmentally friendly PET (Polyethylene Terephthalate polyethylene terephthalate) heat-shrinkable tubing, as an environmentally friendly alternative to PVC (Polyvinyl chloride polyvinyl chloride) heat-shrinkable tubing, can basically replace PVC in the heat-shrinkable tubing industry Thermal casing. PET heat-shrinkable tubing is better than PVC heat-shrinkable tubing in terms of shrinkage, heat resistance, water resistance, and solvent resistance. In terms of flame retardancy, PVC heat-shrinkable sleeves are in the mature stage, while PET heat-shrinkable sleeves are almost in their infancy. As a halogen-free product, environmentally friendly PET heat-shrinkable tubing has a relatively na...
