Embodiment Construction

[0012] A modified colemanite for low-smoke, halogen-free, flame-retardant cable sheathing materials, made of the following raw materials in weight (kg): colemanite 33, boehmite 27, 1,2-propylene glycol carbonate 5 , jojoba oil 7, magnesium naphthenate 1.5, lanthanum malate 1, seashell mud 8, zinc phosphate 6, melamine cyanurate 4, lanolin wax alcohol polyoxypropylene ether 2.5, tricresyl phosphate 8, boric acid Trimethyl ester 6, p-tert-butylcatechol 1, composite additive 4;

[0013] The preparation method of described compound auxiliary agent is as follows: a, get the raw material of following weight (kg): diethyl glutarate 4, oxaloacetic acid 2, discarded molding sand 10, organosilicon microsphere 4, neodymium neodecanoate 1, Cocamidopropyl amine oxide 2, ochre powder 3, cellulose acetate butyrate 2, lanolin magnesium soap 3, cobalt boroacylate 2, N-ethyl-o, p-toluenesulfonamide 1; b, waste molding sand 1. Add diethyl glutarate to a high-speed mixer and stir to 60°C, add co...

Abstract

The invention discloses modified colemanite for a low-smoke, halogen-free and flame-retardant cable sheath material and a preparation method of the modified colemanite. The modified colemanite is prepared from the following raw materials in parts by weight: 25-40 parts of colemanite, 18-32 parts of boehmite, 4-7 parts of 1,2-propylene carbonate, 5-8 parts of jojoba oil, 1-2 parts of magnesium naphthenate, 1-2 parts of lanthanum malic acid, 5-10 parts of seashells mud, 4-8 parts of zinc phosphate, 3-6 parts of melamine cyanurate, 2-3 parts of lanolin ceryl alcohol polyoxypropylene ether, 5-10 parts of tricresyl phosphate, 4-8 parts of trimethyl borate, 1-2 parts of p-tert-butyl catechol and 3-6 parts of a compound additive. The modified colemanite disclosed by the invention is good in flame retardant efficiency; after the modified colemanite is added, the smoke density of a polymer and a toxic gas can be greatly reduced; meanwhile, no irritant halogen hydride gas is generated; and the modified colemanite is safe, environment-friendly and wide in application range.

Description

technical field [0001] The invention relates to a modified colemanite for a low-smoke, halogen-free, flame-retardant cable sheath material and a preparation method thereof, belonging to the technical field of polymer processing. Background technique [0002] Colemanite is a hydrous calcium borate mineral formed from boronite and borax. Its main component is 2CaO·3B 2 o 3 ·5H 2 O. As a natural mineral, colemanite is rich in resources and low in price. It can be used as a flame retardant to replace the more expensive zinc borate, and is widely used as a filler flame retardant for plastic and rubber products. However, the colemanite currently on the market has a low filling function and cannot meet the requirements of multifunctional fillers, which limits the application range. Therefore, colemanite must be modified to improve its comprehensive performance. Contents of the invention [0003] The purpose of the present invention is to provide a modified colemanite for low...
