Description
Technical field the present invention relates to a kind of magnesium hydroxide flame retardant composite polyethylene material, particularly a kind of magnesium hydroxide flame retardant composite polyethylene material of high tenacity.
The background technology polyethylene has been widely used as a lot of aspects such as the coating material, upholster material, wrapping material of cable and wire, but its oxygen index has only 18.5, belong to inflammable material, in order to improve the flame retardant resistance of polythene material, the general employing added halogenide, antimonous oxide and other retardant synergist, but the shortcoming of these fire retardants produces poisonous, mordant halogenide when being burning, smog is big, the personnel that cause poison, and evacuate difficulty, therefore adopt magnesium hydroxide (Mg (OH)
2), aluminium hydroxide (Al (OH)
3) halogen-free flame retardants replacement halogen system, phosphorus commonly used is, the nitrogen flame retardant adds in the polymer materials, when material was met fire burns, oxyhydroxide can absorb the burning liberated heat, produced water and oxide compound, suppress the polymer materials burning, and reach the purpose of Halogen, low cigarette.
Because being the water that relies on the halogen-free flame retardants generation, bittern-free flame-proof material reaches the flame-proofed polymer material purpose, therefore halogen-free flame retardants need reach higher addition, be generally more than the 50-60% (weight percentage), just might play the effect of flame-retardant polymer.High addition causes the polymer materials mechanical property, especially the decline significantly of toughness and intensity.
People such as Wang Yanli, Zhang Yong has reported a kind of halogen-free flame retardants magnesium hydroxide filling high-density polyethylene material on " Chinese plastics " 2000 the 14th the 2nd phases of volume, adopt the method for adding hydroxy silicon oil and titanate coupling agent surface treatment magnesium hydroxide to improve the mechanical property of material, when the magnesium hydroxide addition of titanate coupling agent processing is 58.3% (weight percentage), add 5 parts of hydroxy silicon oils again, the tensile strength of magnesium hydroxide filled polyethylene material is 12MPa, elongation at break is 53.3%, and the Charpy notched Izod impact strength is 13KJ/m
-2, when increase hydroxy silicon oil addition reached 10 parts, the toughness of magnesium hydroxide packing material improved, and the tensile strength of material descends.
Zhong Mingqiang, Song Xubing have reported the method with organo-silicone rubber/organic acid salt modified magnesium hydroxide, aluminium hydroxide halogen-free fire-retardant polyethylene material on " plastics " 1993 the 22nd the 1st phases of volume, when the aluminium hydroxide addition is 40 weight parts, when adding the organo-silicone rubber of 10 weight parts/organic acid salt again, the oxygen index of polythene material reaches 24, and the tensile strength of material only is 9.6MPa.
Reported a kind of polymolecularity aluminium hydroxide fire retardant that makes with the method for sodium aluminate, aluminium sesquioxide stirred crystallization in containing polyprotonic acid, adipic acid solution in the European patent EP 327660, the oxygen index that adds the polythene material of ordinary hydrogen aluminum oxide is 25.1, tensile strength is 4.2MPa, and the oxygen index that adds the polyethylene anti-flaming material of polymolecularity aluminium hydroxide can reach 31.6, and tensile strength is also brought up to 11.7MPa.
Halogen-free flame retardants is under high addition in the prior art, and toughness of material is poor, and intensity is low, is difficult to prepare have good toughness and the high polyethylene bittern-free flame-proof material of intensity concurrently.
Summary of the invention the objective of the invention is to overcome above-mentioned shortcoming, and a kind of have simultaneously high tenacity and high-intensity magnesium hydroxide flame retardant composite polyethylene material are provided.
