Description
Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of antibacterial refrigerator power cord flame-proof polyethylene and protect
Jacking 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, rises
Effect to 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 to occur
Leaky.The sheath of refrigerator power cord can be divided into oversheath and inner sheath, and oversheath also referred to as protects sheath, is refrigerator
The outmost one layer of sheath of power line, this layer of oversheath plays a part to protect power line.High density polyethylene (HDPE) (HDPE) is should
Use most commonly used general-purpose plastics, because of its good electrical insulating property, mechanical performance, dielectric properties, easy machine-shaping, heat-resisting cold-resistant
And chemical-resistance is applied to making refrigerator power cord protective cover material, but due to the low easy firing of the oxygen index (OI) of HDPE, aging resistance
Property and the performance such as flexible resistance low, therefore, it is carried out the performances such as fire-retardant, aging resistance and flexible resistance and is modified having especially
Important meaning.
Having halogen fire retardant is the fire retardant being currently mainly applied to HDPE, has the most fire-retardant and mechanical property, but because of it
Hazardness to environment is the most gradually eliminated.Magnesium hydroxide is a kind of novel halogen-free flame-retardant agent in recent years developed, and has decomposition temperature
The advantages such as degree height, Heat stability is good, have 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, in certain journey
Improve its degree that is uniformly dispersed in macromolecular material on degree, but still fail to reach desirable.To magnesium hydroxide surface
The modified hydrophobicity that can improve magnesium hydroxide to a certain extent, 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 " one
Literary composition is by silane coupler, magnesium stearate and titanate esters surface modification magnesium hydroxide blending HDPE respectively, and result shows
Show: high density polyethylene (HDPE) anti-flammability is improved less by silane coupler, magnesium stearate and titanate esters modified magnesium hydroxide, but favorably
In improving system mechanical property.Considering combination property, silane coupler is best surface modifying agent, and consumption is magnesium hydroxide quality
3.5% time, 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, quick along with science and technology
Development, 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 that it is filled with enhancing modified, filling-modified by filler
Modified kind can be divided into inorganic filler and organic filler.From environmental protection consider conventional be add to high density polyethylene (HDPE) inorganic
Filler, such as calcium carbonate, Pulvis Talci, glass microballoon, Muscovitum etc., although the raising intensity of material, rigidity, size can be played steady
The effect of the performance such as qualitative, but these inorganic filler relative densities are relatively big, add the composite making preparation in polymer
Relatively denser, cause product quality to rise, and between inorganic filler and organic polyethylene, the compatibility is bad, need inorganic material
Material carries out surface modification, just can preferably be combined with matrix, and preparation technology is complex, relatively costly.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of antibacterial refrigerator power cord is by fire-retardant poly-second
Alkene protective cover material and preparation method thereof.
The present invention is achieved by the following technical solutions:
