Embodiment 1～12

[0037] The halogen-free intumescent flame-retardant wire and cable insulation material composition is prepared by the following method:

[0038] (1) Preparation of macromolecular triazine oligomer:

[0039] Add 46.1g of cyanuric chloride in the 500ml reaction flask equipped with reflux condenser, constant pressure dropping funnel, stirrer and thermometer, then add 10ml acetone and 10ml distilled water, fully stir, cyanuric chloride is dispersed evenly, Then, under the condition of -5~5℃, 15.3g of ethanolamine and NaOH solution (10gNaOH dissolved in 25ml of distilled water) were evenly added dropwise while stirring. Hour. Then raise the temperature to room temperature, then evenly add 9.25g, 1,3-propanediamine and NaOH solution (10gNaOH dissolved in 25ml distilled water) dropwise to the reaction flask, raise the reaction temperature to 40~65°C after the dropwise addition , Stir the reaction under these conditions for 4 to 6 hours. Then, under the condition of 40~65 DEG C, co...

Abstract

The invention relates to a halogen-free intumescent flame retardant wire/cable insulating material composition. The formula of the materials of the composition is as follows: 60 to 80 percent by mass of polyolefin; 15 to 35 percent by mass of halogen-free intumescent flame retardant; 2 to 10 percent by mass of synergist; 1 to 10 percent by mass of compatilizer; 0.1 to 1 percent by mass of lubricant; and 0.1 to 1 percent by mass of antioxidant. Compared with the prior art, the composition has the advantages that: dosage is low, the flame-retardant property is high, no harmful substances are released and the color cannot be changed in the process of processing and use, and precipitation resistance and water resistance are good. The composition has good flame-retardant property and toughness, and is particularly suitable for use in the fields of wires/cables, electronics/electricity, house decoration, automobile industry and the like which have strict requirement on flame retardance.

Description

technical field [0001] The invention relates to a halogen-free intumescent flame-retardant polyolefin composition, in particular to a halogen-free intumescent flame-retardant wire and cable insulating material composition. Background technique [0002] Wires and cables have been used in the transmission of various electrical energy and signals for many years. Due to their light weight, excellent electrical insulation and easy molding, polymer materials have become the first choice for wire and cable materials. Traditional PVC cable materials, because they contain chlorine elements, have very good flame retardancy and are widely used in wire and cable materials. However, when it burns, it generates a large amount of toxic gas and smoke, which seriously endangers people's lives and property safety. The hydrogen chloride gas released when the PVC cable material is burned can also cause corrosion to the equipment, thereby causing "secondary pollution". In 2003, the European Un...
