Description

A kind of can be termite-proof refrigerator power cord flame-retardant polyethylene sheathing material and preparation method thereof
Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of refrigerator power cord flame-retardant polyethylene sheathing material that can be termite-proof and preparation method thereof.
Background technology
It is known that power line is the electric wire of transmission electric current, wherein sheath is the indispensable structure division of power line, plays the effect of protection wire insulation, it is ensured that the energising safety of power line, allows conductor and the medium such as water, air completely cut off, it is to avoid leaky occur.The sheath of refrigerator power cord can be divided into oversheath and inner sheath, and oversheath also referred to as protects sheath, is the outmost one layer of sheath of refrigerator power cord, and this layer of oversheath plays a part to protect power line.High density polyethylene (HDPE) (HDPE) is the general-purpose plastics being most widely used, because its good electrical insulating property, mechanical performance, dielectric properties, easy machine-shaping, heat-resisting cold-resistant and chemical-resistance are applied to making refrigerator power cord protective cover material, but owing to the performances such as the low easy firing of the oxygen index (OI) of HDPE, ageing resistance and flexible resistance are low, 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 along with the fast development of science and technology, the performance such as wear-resisting, anticorrosion, the oil resistant of existing refrigerator power cord protective cover material the most more and more cannot meet the demand in market.High-density polyethylene modified method also has a lot, and 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, product quality is caused to rise, 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.
Summary of the invention
