Embodiment approach 2

[0013] Embodiment 2: Take 100 parts of ethylene vinyl acetate copolymer (EVA), 50 parts of ammonium polyphosphate flame retardant, 1 part of antioxidant 1010, 1 part of ZnSt, 4 parts of white masterbatch, mix the above materials, double Screw blending and granulation can produce materials for the production of white halogen-free flame-retardant heat-shrinkable sleeves and cross-linked wires and cables. The flame retardant grade of the product can reach the American UL standard UL224VW-1 flame retardant grade.

Embodiment approach 3

[0014] Embodiment 3: Take 60 parts of ethylene vinyl acetate copolymer (EVA), 30 parts of ethylene acrylic acid copolymer (EEA), 10 parts of linear low-density polyethylene (LIDPE), 80 parts of ammonium polyphosphate flame retardant, 1 part of anti Oxygen 1010, 1 part of MgSt, 3 parts of plastic red masterbatch, the above substances can be mixed and granulated by twin-screw blending to produce halogen-free flame-retardant heat-shrinkable sleeves and cross-linked wires and cables in various colors s material. The flame retardant grade of the product can reach the American UL standard UL224VW-1 flame retardant grade.

Abstract

The invention relates to a material used for a halogen-free, flame retardant and thermal shrinkage sleeve and crosslinked wires and cables as well as the preparation method, aiming to provide a material and the preparation preparation method for halogen-free, flame retardant and thermal shrinkage sleeve and crosslinked wires and cables in diversified colors. The preparation method comprises the following steps: first, evenly mixing the compound formed by polyolefin copolymer, silicon rubber, halogen-free ammonium polyphosphate composite fire retardant, lubricant, colorant color master batch and antioxidant in specific proportions through a high speed mixer, then extruding and granulating the compound by means of the mechanical blending, finally turning out the material for producing the halogen-free flame retardant and thermal shrinkage sleeve and crosslinked wires and cables.

Description

technical field [0001] The invention relates to a material for producing halogen-free flame-retardant heat-shrinkable sleeves and cross-linked wires and cables and a preparation method thereof, in particular to a material for producing halogen-free flame-retardant heat-shrinkable sleeves and cross-linked wires and cables of various colors. Material and preparation method of connecting wire and cable. Background technique [0002] At present, the halogen-free flame-retardant heat-shrinkable sleeves and cross-linked wires and cables on the market are produced with flame retardants containing red phosphorus. Therefore, only black halogen-free flame-retardant heat-shrinkable sleeves and Cross-linked wire and cable, but can not produce other colors of halogen-free flame-retardant heat shrinkable sleeve and cross-linked wire and cable. Contents of the invention [0003] The object of the present invention is to provide a material and a preparation method for producing halogen-f...
