[0036] (1) Mix cyanuric chloride and tetrahydrofuran in a mass ratio of 1:4.1, and dropwise add 2.3 times the mass of cyanuric chloride with a mass fraction of 53% 3-aminopropyltriethoxysilane at a rate of 5ml / min. The tetrahydrofuran solution was added dropwise with a triethylamine solution with a mass of 1.9 times the mass of cyanuric chloride at a rate of 5ml / min. The mass ratio of triethylamine to tetrahydrofuran in the triethylamine solution was 2.2:1. , Rotary steam at 35°C to constant weight to prepare base material; mix base material with absolute ethanol at a mass ratio of 1:2.5 and stir until dissolved, and dropwise add 2 times the mass of base material at a rate of 5ml / min. The mass fraction is 9 % sodium hydrosulfide in ethanol, heated to 55°C, reacted for 3.5h, rotary-evaporated at 0.9MPa and 46°C to obtain s-triazinedithiolsilane;

[0037] (2) mixing magnesium hydroxide and deionized water in a mass ratio of 1:6, heating to 75° C., stirring to make a slurry, addi...

Embodiment 3

[0043] (1) Mix cyanuric chloride and tetrahydrofuran in a mass ratio of 1:4.2, and dropwise add 2.5 times the mass of cyanuric chloride with a mass fraction of 54% of 3-aminopropyltriethoxysilane at a rate of 8 ml / min. The tetrahydrofuran solution was added dropwise to a triethylamine solution with twice the mass of cyanuric chloride at a rate of 8ml / min. The mass ratio of triethylamine to tetrahydrofuran in the triethylamine solution was 2.5:1. After the reaction for 18h, at 0.9MPa Rotary steam to constant weight at 35°C to obtain base material; mix base material with absolute ethanol at a mass ratio of 1:3 and stir until dissolved, and dropwise add 3 times the mass of base material at a rate of 8ml / min. The mass fraction is 10 % sodium hydrosulfide in ethanol, heated to 60°C, reacted for 4h, and rotary-evaporated at 0.9MPa and 46°C to obtain s-triazinedithiolsilane;

[0044] (2) mixing magnesium hydroxide and deionized water in a mass ratio of 1:8, heating to 80° C., stirrin...

Abstract

The invention discloses a high-strength flame-retardant cable material and a preparation method thereof, and relates to the technical field of cable materials. The high-strength flame-retardant cable material prepared by the invention comprises a modified styrene copolymer and a flame-retardant microcapsule, the modified epoxy acrylamide on the modified styrene copolymer enhances the water resistance of the cable material, and meanwhile, a rigid chain segment is introduced to prevent the intervention of a corrosive medium, so that the corrosion resistance of the cable material is enhanced; magnesium hydroxide is coated by compounding s-triazine dithiol silane and gamma-mercaptopropyltrimethoxysilane to prepare the flame-retardant microcapsule, and the flame-retardant microcapsule not only can be crosslinked on a modified styrene copolymer to enhance the toughness of the cable material, but also can enhance the flame retardance of the cable material.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength flame-retardant cable material and a preparation method thereof. Background technique [0002] With the rapid development of economy, wires and cables have been widely used in various industries and fields, and have become necessary industrial products for people's life and production. The progress and development of the wire and cable industry first need to take the development of cable materials as the basic condition. Without the innovation and development of cable materials, the development of the wire and cable industry is nothing but empty talk; the plastics used for wire and cable insulation and sheathing are commonly known as cable materials, which include Rubber, plastic, nylon and other varieties. Cable material production enterprises are based on cable production enterprises, and as long as there is a demand for wires and cables, there is a mar...
