The technical scheme provided by the invention integrates the advantages of the non-ionic antistatic agent of being good in compatibility and thermal stability, and free from adverse effects on the physical-mechanical property of a material, with the advantages of the carbon black of being low in filling modification cost and good in effect, researches and develops a PE modified material low in cost and high in antistatic property, and provides the foundation for development on antistatic PE tubes or tube fittings.
Description
Technical field
The present invention relates to a kind of antistatic type PE material and preparation method thereof.
Background technology
The common positive and negative charge that has of any object is an equivalent.Different objects is through mechanical effects such as friction, contacts; Electric charge will move through contact interface, on an object, causes positive excess, and then negative charge is superfluous on another object; And on the interface, form electrical double layer, and the space outside the two articles does not present electrostatic phenomenon.But when on this contact surface, applying any mechanical effect two objects are separated, then on each object, produce static respectively, and the outside electrostatic field that forms.Static and electrostatic field have three kinds of important effects and physical phenomenon, i.e. the effect of power, electric discharge phenomena and static induction phenomenon.
Vilaterm has superior electrical insulation capability, has very high face resistance and body resistance, when phase mutual friction or contact separation, will produce very high static.Resistance is big more, and static discharges just slow more, and static charge accumulation to a certain degree will cause static discharge.
Polyethylene tube is one of most popular plastic pipe in the world, the tenacity excellent of polyethylene tube, shock resistance, nontoxic, and polyethylene tube can be easy to be used widely through the molten solder assembling.At present, the pipeline that be used to feed water, buried pipeline all adopts the Vilaterm material mostly among the public works such as combustion gas.Therefore, when tubing and pipe fitting use,, need excellent antistatic property, otherwise will produce immeasurable loss and serious consequence in particular for the pipeline material of gas supply.
The antistatic property of superpolymer can be regarded the ability that this material is eliminated static charge fast as; Therefore; Generally can improve the antistatic property of superpolymer in the following manner; Carry out top coat or carry out blending and modifying with surfactivity type static inhibitor, prepare the compound-type conducting superpolymer through copolymerization or blend, electroconductibility stopping composition blending and modifying and some physical modification methods with conducting polymer.
Expand for the safe handling and the field that guarantee polyethylene tube, have low cost, the research and development of the PE material that antistatic property is excellent are extremely urgent.
Summary of the invention
The purpose of this invention is to provide a kind of antistatic type PE material and preparation method thereof, in order to solve defective and the deficiency that above-mentioned prior art exists.
Be the realization above-mentioned purpose, a kind of antistatic type PE material of the present invention, it comprises the component of following weight part proportioning:
The consistency of said non-ionic antistatic agent and thermal stability are good, the physical-mechanical properties of material is had no adverse effects, but consumption are relatively large, in order to overcome this defective, remedy through adding conductive filler material, simultaneously the control material cost;
Further, said non-ionic antistatic agent is the polyoxyethylene etcetera;
Said graft modification carbon black is that the hindered phenol small molecules is grafted to the grafts that carbon blacksurface forms through covalent linkage, has increased the wellability with polyvinyl through graft modification;
Further, said carbon black is selected from more than one in acetylene black, furnace black and the channel black;
Further, said hindered phenol small molecules Irganox1076, Irganox1330 or Irganox3114;
Further, said graft modification sooty percentage of grafting is that the hindered phenol small molecules mass percent that comprises in every 100g carbon black is 5%～20%;
Further, said oxidation inhibitor comprises that primary antioxidant 1010 is 5～10 parts, 1～5 part of aid anti-oxidants thio-2 acid two lauryl alcohol ester (DLTP), and wherein DLTP also has certain antistatic property.
The present invention also provides above-mentioned antistatic type PE preparation methods, and it comprises the steps:
1) in proportion above-mentioned antistatic type PE material component is put into super mixer, mixing time 1～15min;
2) with the material that mixes through the twin screw extruder extruding pelletization, prilling temperature is controlled at 150～220 ℃.
Further, mixing time is 5～10min in the said step 1), and there are optimum value in static resistance and mixing time; When just beginning to mix, the dispersion of shearing force accounts for main effect, so static resistance prolongs in time and raises; After reaching optimum value; Shearing force accounts for leading role to structural damage, so the time is long more, static resistance is poor more.
A kind of antistatic type PE material provided by the invention; The consistency and the thermal stability that combine non-ionic antistatic agent are good; To advantage and low, the effective advantage of carbon black filled modification cost that the physical-mechanical properties of material has no adverse effects, developed low cost; The PE of high-antistatic property is material modified, for its exploitation at antistatic type PE tubing or pipe fitting provides the foundation.
