Embodiment 1

[0025] The flame retardant synergist used in Example 1 is the product of the reaction of hexachlorocyclotriphosphazene and 3-aminopropyltriethoxysilane. The preparation method is as follows: first dissolve hexachlorocyclotriphosphazene in tetrahydrofuran, and then Add triethylamine, put it into a clean and dry reaction tube and let it be protected by nitrogen, then add 3-aminopropyltriethoxysilane dropwise, stir the reaction magnetically at 0°C for 4 hours and stop the reaction; The mixture was filtered to remove the insoluble triethylamine hydrochloride, the salt was washed with tetrahydrofuran and the washing solution was incorporated into the filtrate, and the tetrahydrofuran solvent was removed by rotary evaporation to obtain an oily substance. The mixture was washed with ether for 2-3 times, and the solution was rotated. Steam to obtain an oily substance, and finally wash 2-3 times with petroleum ether, and vacuum dry for 24h to obtain an oily product; wherein, the molar ra...

Abstract

The invention discloses a halogen-free flame retardant irradiation-crosslinked cable material. The halogen-free flame retardant irradiation-crosslinked cable material comprises, by weight, 100 parts of an ethylene propylene diene monomer, 35 to 100 parts of an inorganic flame retardant filler, 2 to 20 parts of a flame retardant synergist, 2 to 8 parts of a dispersant, 0.5 to 2 parts of an antioxidant and 0.5 to 2 parts of a crosslinking agent. Through use of the flame retardant synergist, the inorganic flame retardant filler and the crosslinking agent in a polyolefin cable material, mechanical properties are improved. The flame retardant synergist can produce intumescent flame retardancy in cable material burning and the flame retardant synergist and the inorganic flame retardant filler form an obstruction layer so that combustion-supporting gas obstruction is realized and the use amount of the inorganic flame retardant filler is reduced. Through the electron beam irradiation to the ethylene propylene diene monomer, an ethylene propylene diene monomer molecular chain is crosslinked so that the overall performances and flame retardant effects of the cable material are improved.

Description

Technical field [0001] The invention relates to a wire and cable material, in particular to a radiation crosslinked polyolefin cable material containing an inorganic flame-retardant filler and a flame-retardant synergist and a preparation method thereof. Background technique [0002] With the rapid development of polymer materials, the flame retardant technology research of this kind of materials is increasingly extensive and in-depth. The commonly used flame retardants can be mainly divided into inorganic metal hydroxides and halogen-containing flame retardants. Inorganic metal hydroxides decompose during the combustion process and absorb a lot of heat. At the same time, the oxides generated can be coated on the surface of the polymer to isolate air and heat to achieve a flame retardant effect. However, due to the low flame retardant efficiency, it needs to be added A large amount can achieve a better flame retardant effect, and the greater polarity of these substances leads to ...
