Description
Technical field
The present invention relates to tubing, specifically a kind of fire retardant, antistatic polyethylene pipe material and preparation method thereof.
Technical background
In recent years, because polyvinyl piping materials has the advantages such as inexpensive light weight, easy for installation, environmental protection, add the promotion of national policy, be widely used in every field.Plastic pipe has good corrosion resistance, cost is low, lightweight, the life-span long, advantage easy for installation, but plastics tubing has and very easily produces electrostatic, inflammable, resistance toly forces down with poor impact resistance, makes the shortcomings such as formula is complicated, operation inconvenience simultaneously, therefore, further adjustment awaited to polythene material, improves, improve its performance.
Mineral polyethylene piping materials is except should possessing the physical and mechanical properties of general plastic pipe, and namely the particular requirement that also should meet colliery must have static resistance, self-extinguishing and products of combustion also must not have toxicity.Polyethylene is a kind of organic polymer material, and its volume specific resistance is very high, will produce electrostatic, and be gathered in frosting through friction, can fire hazard and gas explosion, therefore must carry out antistatic modified to the polyvinyl resin producing pipes for mining.At present conventional method of modifying comprises add static inhibitor or the material such as conductive carbon black and metal-powder in resin.Static inhibitor is a kind of surfactant, and its anlistatig mechanism is that the water-wet side of static inhibitor absorbs the moisture content in air, forms a kind of conduction moisture film, thus reduces surface resistivity, make the static charge produced thank rapidly at material surface.If the static inhibitor on surface is because of washing or wipe backward, inner static inhibitor molecule can also shift to surface, thus recovers its antistatic property.
Graphitized carbon black is added, because carbon structure has larger specific surface area and good surface chemical property, so can obtain good antistatic effect in polyethylene.In the past due to the problem of the performance of carbon black own, the consumption of carbon black reached more than 20 parts, and polyethylene just can be made to have good antistatic property, but at this moment Drawing abillity, mechanical property are deteriorated, and its application in tubing is restricted.ZL90106274 discloses a kind of manufacture method of polyethylene hose, and the add-on of its carbon black is more than 20 parts, and this patent utilization crosslinking technological compensate for the mechanical property loss of energy adding a large amount of carbon black and cause.Along with the development of black carbon technology, the carbon black adding less number in recent years in the composite just can obtain good antistatic effect, but because the specific surface area of graphitized carbon black is very big, add the melt viscosity that will have a strong impact on matrix material in resin, in extrusion, there will be moment of torsion excessive, extrude the phenomenons such as unstable.
Summary of the invention
The object of the present invention is to provide a kind of antistatic and flame retardant synergistic effect is good, good toughness, quality soft, intensity is high, and Easy dosing, preparation are easy to fire retardant, antistatic polyethylene pipe material and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is:
A kind of fire retardant, antistatic polyethylene pipe material, its feed composition is by weight percentage: high density polyethylene(HDPE) (HDPE) 40%-60%, zinc borate 10%-20%, conductive nano carbon black 20%-40%, coupling agent 1%-5%, auxiliary 1%-5%.
Further, described conductive nano carbon black comprises one or more in N330, N220, N550.
Further, described coupling agent is aluminate coupling agent.
Further, described auxiliary comprises oxidation inhibitor and stopping composition composition.
A kind of making method of fire retardant, antistatic polyethylene pipe material:
1) by each feed composition components by weight percentage mixing, then fully 8-12 minute is stirred through high-speed kneading machine, more blended granulation in single screw extrusion machine;
2) extruded by pipe mill and tube extrusion auxiliary machine by the particle obtained in step 1) again, dry, squeeze pipe, cooling, sizing, traction, coiled by curler, get product tubing.
Being employed herein high density polyethylene(HDPE) (HDPE) resin, is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.The milky appearance of ortho states high density polyethylene(HDPE), translucent in meagre cross section in a certain degree.High density polyethylene(HDPE) has excellent resistance to great majority life and the characteristic of chemicals for industrial use.Non-hygroscopic and the steam-preventing had of this polymkeric substance, can be used for packing purposes.High density polyethylene(HDPE) has good electrical property, and particularly dielectric strength is high, makes it be applicable to electric wire very much.In to high molecular weight grades, there is fabulous shock resistance, even all like this under-40 DEG C of low temperatures at normal temperature.
Beneficial effect of the present invention is:
Fire retardant, antistatic polyethylene pipe material of the present invention is antistatic and flame retardant synergistic effect is good, has excellent antistatic property and flame retardant properties, lightweight, quality is soft, good toughness, can coil, corrosion-resistant, can the erosion of resistance to various chemical mediator, its inner wall smooth, resistance is little, less scaling in using, wear resistance is run well than rubber hose and pure polyethylene, and Easy dosing, preparation are easy.Tubing of the present invention can replace steel pipe completely and be widely used in draining, water supply, pressure wind and gas drainage, and non-toxic sanitary is lightweight, easy construction.
