Abstract
The invention discloses an antistatic flame-retardant polyethylene material for geogrids. The nano magnesium hydroxide is subjected to surface modification by silane to obtain a flame retardant, thereby improving the hydrophobicity of magnesium hydroxide to some extent, enhancing the compatibility of the magnesium hydroxide in the polymer, and achieving the effect of enhancing the mechanical properties and flame retardancy of the material. The red phosphorus is subjected to encapsulation modification to improve the problems of high moisture absorption tendency and poor safety in the red phosphorus; and the encapsulation-modified red phosphorus is heated to form phosphoric acid and metaphosphoric acid so as to form the strong dehydrating agent polymetaphosphoric acid, thereby accelerating the decomposition of the magnesium hydroxide and performing the synergic flame-retardant function. The inorganic filler mica powder surface is subjected to chemical modification to enhance the compatibility in the polymer and improve the mechanical strength and wear resistance of the product; and by compounding other effective aids, the prepared polyethylene material has favorable flame retardancy, can resist static electricity when being used as a geogrid material in mines, and has the advantages of higher strength and favorable aging resistance.
Description
Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of can the GSZ fire-retardant polyethylene material and preparation method thereof of antistatic.
Background technology
Plastics Geogrids be added auxiliary agent by polypropylene (PP) or high density polyethylene (HDPE) (HDPE) after add in extruder after melted by heating under the push effect of screw rod, through the one netted novel plastic engineering material of special rotating head extrusion molding.Its medium high density polyethylene GSZ has the features such as light weight, intensity shock resistance high, corrosion-resistant, length in service life, is usually used in the various aspects such as highway, railway, harbour, vacation top, colliery, building safety.But high density polyethylene (HDPE) is a kind of incendive material, and it is difficult to after catching fire extinguish, affects the application of high density polyethylene (HDPE) GSZ.Therefore, it is carried out the meaning that the performances such as fire-retardant, aging resistance and flexible resistance are modified having particular importance.
Having halogen fire retardant is the fire retardant being currently mainly applied to HDPE, has the most fire-retardant and mechanical property, but because the hazardness of environment is the most gradually eliminated by it.Magnesium hydroxide is a kind of novel halogen-free flame-retardant agent in recent years developed, and has the advantages such as decomposition temperature height, Heat stability is good, has been widely used in plastic material.But its flame retarding efficiency is relatively low, often need to add in a large number, and poor with polymer compatibility, dispersion inequality, it is difficult to independent use.Although nano-sized magnesium hydroxide surface area is big, improves its degree that is uniformly dispersed in macromolecular material to a certain extent, but still fail to reach desirable.Magnesium hydroxide surface modifying can be improved to a certain extent the hydrophobicity of magnesium hydroxide, thus improve its compatibility in the material, and reach to improve the mechanics of materials and the effect of anti-flammability." surface modification impact on nano-sized magnesium hydroxide/high-density polyethylene composite material " literary composition is by silane coupler, magnesium stearate and titanate esters surface modification magnesium hydroxide blending HDPE respectively, result shows: high density polyethylene (HDPE) anti-flammability is improved less by silane coupler, magnesium stearate and titanate esters modified magnesium hydroxide, but beneficially raising system mechanical property.Considering combination property, silane coupler is best surface modifying agent, and when consumption is the 3.5% of magnesium hydroxide quality, system oxygen index (OI), hot strength, elongation at break and impact strength are respectively increased about 8%, 30%, 6% and 18%.
But, in literary composition, only anti-flammability to HDPE has carried out modification, and flame retardant effect is general, and high-density polyethylene modified method also has a lot, more conventional is is filled with enhancing modified to it, filling-modified can be divided into inorganic filler and organic filler by filler modified kind.Consider that conventional is addition inorganic filler to high density polyethylene (HDPE) from environmental protection, such as calcium carbonate, Pulvis Talci, glass microballoon, Muscovitum etc., although the intensity improving material can be played, rigidity, the effect of the performances such as dimensional stability, but these inorganic filler relative densities are bigger, add and polymer makes the composite prepared relatively denser, the Some Mechanical Properties parameter causing HDPE declines, and the compatibility is bad between inorganic filler and organic polyethylene, need inorganic material is carried out surface modification, just can preferably be combined with matrix, preparation technology is complex, relatively costly.
