The forming process for the clad material comprises, mixing 100 weight parts of inorganic electrostatic resistant filling material, 2-15 weight parts of polymerisable monomer, 0.1-1 weight part of initiating agent, carrying out polymerization reaction, finally disintegrating.
Description
Technical field
The present invention relates to a kind of polymeric antistatic masterbatch of filling mineral filler.
Background technology
Macromolecular material comprises that polyethylene, polypropylene, ABS, polyvinyl chloride, polystyrene etc. are by the molecular weight ratio bigger polymkeric substance of resin monomer through being polymerized.With inorganic materials (filler) filled high polymer material, can give macromolecular material some properties, as flame retardant properties, antistatic property, rigidity, and reduce cost.Wherein the polymeric antistatic material has purposes widely, can be used to make the inside and outside shielding material of high-tension cable, mining pipes, electromagnetic shielding material, packed and transported material of electronic product or the like.Its production method generally is made into masterbatch earlier, produces PP Pipe Compound together with masterbatch and raw material again, makes goods according to the purposes of reality.Traditional masterbatch production method is to utilize the coupling agent treatment mineral filler, again with the macromolecule resin blend, but this treatment process just combines with macromolecular material at several points on the surface of mineral filler, be that interface between them is in conjunction with bad, influenced the mechanical property of macromolecular material, low as intensity, toughness is bad etc.
Summary of the invention
Technical problem to be solved by this invention provides the polymeric antistatic masterbatch that a kind of mineral filler and macromolecular material interface junction get togather.
Polymeric antistatic masterbatch of the present invention, comprise inorganic antistatic filler and macromolecule resin, it is characterized in that described inorganic antistatic filler is coated the formation coating material by organic monomer, by weight percentage, comprises the macromolecule resin of coating material 50-80% and surplus.
Also can add the lubricant of 3-5% in the antistatic master batch for the ease of processing, lubricant can be selected whiteruss, polyethylene wax for use.
The production method of polymeric antistatic masterbatch be each raw material mix in twin screw extruder extrude, fusion, plasticizing, granulation form.The present invention does not change main raw material and forms, and has just changed the adding mode of mineral filler, with the form of coating material and melt polymer material, blend.
Described inorganic antistatic filler preferably adopts conductive carbon black, graphite.For example, use the conductive carbon black filled polyethylene, have antistatic property, can be used to produce antistatic mining pipes etc.
Macromolecule resin can be polyethylene, polypropylene, ABS, polyvinyl chloride, polystyrene, terpolymer EP rubber or the like.
The production method of coating material is: the mineral filler of 100 weight parts and polymerisable monomer 2～15 weight parts, initiator 0.1～1 weight part Hybrid Heating are carried out polyreaction, pulverize after the polyreaction and obtain coating material, described polymerisable monomer be with macromolecule resin can be compatible organic monomer.
Polymeric reaction temperature is generally 50～95 ℃, and polymerization reaction time is generally at 2～4 hours.
The macromolecular material that described polymerisable monomer is meant and is filled can be compatible monomer material, comprise that vinylformic acid, esters of acrylic acid (as methyl acrylate, ethyl propenoate, butyl acrylate), maleic anhydride, vinyl cyanide, vinylbenzene etc. contain the monomer of two keys.Polymerisable monomer is coated on inorganic filler surface, can combine well with macromolecular material.
Described action of evocating is to cause the polymerisable monomer polymerization reaction take place, comprises all kinds of superoxide (as dicumyl peroxide, ditertiary butyl peroxide), iron protoxide, persulphate (as Potassium Persulphate, ammonium persulphate, Sodium Persulfate) etc.
Because inorganic materials and organic materials consistency extreme difference, exist between the interface in conjunction with problem, so in the organic polymer material during heavy addition mineral filler, mechanical property influence to organic polymer material is very big, though given the organic polymer material antistatic property, but, often cause organic polymer material not use owing to influenced its mechanical property.The present invention utilizes the polymerisable character of monomer to put on one deck organic " coat " to mineral filler, this coating material that obtains can finely combine with organic polymer material, solved the interface problem of inorganic materials and organic materials, so when giving the organic polymer material antistatic property, and do not influence its mechanical property (mainly showing on intensity and the toughness).
