Description
Technical field
The present invention relates to a kind of production method of composite polyethylene wax super fine, can be used to produce powder coating, can lacquer, UV curing, metal finishing coating, high gloss solvent reducible coatings, water-borne coatings, cardboard moisture-proof coating, solvent borne base gravure ink, lithographic printing/offset printing, printing ink, cover print-polishing oil.Belong to composite polyethylene wax super fine modification technology field.
Background technology
Micronized polyethylene wax micro mist is to be raw material with the polyethylene wax, through the high-tech product of complicated modern production explained hereafter.It has that hardness is big, softening temperature is high, wear resistance is good, heat-resisting, scratch resistance, resistance to wear, characteristics such as good waterproof performance.Molecular-weight average 2000-8000,105 ℃ of softening temperatures, penetration degree is less than 5 (1/10mm), density 0.95g/cm
3, acid number is less than 0.1mgKOH/g, and median size is less than 8 microns.
In coating, paint and printing ink, add 0.5-1.5% micronized polyethylene wax micro mist and will produce excellent resistance to marring, antiskid trace and level and smooth feel.Can improve the smooth feel of coating, paint and ink pellet surface, strengthen scratch resistant performance, improve the performance of product.
Because micronized polyethylene wax micro mist is a kind of high-tech product, each manufacturer all holds in close confidence both at home and abroad, so the concrete production technique that disclosed documents and materials patent is introduced micro mist wax seldom.All use single pure polyethylene wax to be raw material from disclosed data at home and abroad.
Use pure polyethylene wax to have following shortcoming as raw material production micronized polyethylene wax micro mist: micronized polyethylene wax micro mist product softening temperature depends on the fusing point of material polyethylene wax, can not adjust flexibly.The fusing point of general polyethylene wax need reach more than 110 ℃ if wish the fusing point of micronized polyethylene wax micro mist between 101 ℃-110 ℃, will be restricted.The wear resistance of micronized polyethylene wax micro mist product is subjected to the restriction of material polyethylene wax, can not change.If raw material is softer, then the wear resistance of product micronized polyethylene wax micro mist is also very poor, can't change, and is requiring the high field of wear resistance to meet consumers' demand.The penetration degree of micronized polyethylene wax micro mist can not be adjusted flexibly.The penetration degree of polyethylene wax is the performance index of expression polyethylene wax hardness, if the penetration degree of polyethylene wax is bigger, represents that then its hardness is less, represents that its hardness is bigger if the penetration degree of polyethylene wax is less.The hardness of wishing polyethylene wax at last optical arena is big, to improve the wiping properties of lustering agent, if still the hardness of polyethylene wax is less, then is difficult to satisfy user's requirement.
Zhao of Beijing Institute of Technology grassland, rectify the celebrating pool, ask that upright peace gold and jade continent etc. discloses a kind of emulsion process that is used to prepare spherical polyethylene micropowder wax, publication number is CN1884348A.This method adopts organic solvent heating for dissolving cracking polyethylene wax, adds the aqueous solution of tensio-active agent again, forms emulsion under the violent stirring, and cryoprecipitation goes out spherical polyethylene micropowder wax then.This method is simple, and is easy and simple to handle, and cost is low.Use this method and can make particle diameter uniform spherical polyethylene micropowder wax.This invention has overcome complex process in the prior art, defective that energy consumption is big; can large-scale industrial production; what but this method was used is single pure polyethylene wax; the every performance index of micronized polyethylene wax micro mist of its preparation depend on raw materials used, can not adjust the performance index such as softening temperature, penetration degree of polyethylene wax micro mist according to customer requirements.
JP53018233B discloses a kind of chemical method and mechanical process combination process of polyethylene wax micro mistization, and its main raw material is single pure polyethylene wax, uses halon solvents such as solvent trichloroethane, trieline, zellon during production.Adopt the high speed rotating pulverization process at last.The raw material that this method technology is used is single pure polyethylene wax, so material performance is decided by that product performance product physical and chemical performance index can not effectively adjust.
Summary of the invention
The purpose of this invention is to provide a kind of hardness height, softening temperature height, good luster, particle diameter is little, cost is low, treatment capacity is big, the production method of the simple composite polyethylene wax super fine of technology.
For realizing above purpose, technical scheme of the present invention provides a kind of production method of composite polyethylene wax super fine, it is characterized in that, adds Poly Propylene Wax or the mixing of stearylamide Wax additive in the polyethylene wax raw material, and its method is:
The first step. polyethylene wax is mixed with Poly Propylene Wax or stearylamide,
The weight ratio prescription of polyethylene wax and Poly Propylene Wax or stearylamide is:
Polyethylene wax 20-95%, Poly Propylene Wax 5-80%;
Or polyethylene wax 20-95%, stearylamide 5-80%;
Second step. earlier the mixture coarse reduction being made its particle diameter is the 1-5 millimeter;
The 3rd step. it is carried out superfine grinding through adjustable particle diameter formula pulverizer again, suitable pulverizer operational condition is: blast 0.1-2Mpa, input speed be the 1-50 kilogram/hour; Through screening, the wax powder of production directly is: 20 microns one 8 microns, promptly get composite polyethylene wax super fine.
Its molecular weight ranges of described Poly Propylene Wax is from 500-20000; Described stearylamide is ethylene bis stearamide, erucicamide or amine hydroxybenzene.
The present invention mixes polyethylene wax with Waxes such as Poly Propylene Wax, ethylene bis stearamides, adopt pulverizing, screening technology production Superfines Polymeric Wax Powder again.
Poly Propylene Wax of the present invention is meant the Poly Propylene Wax that cracking process and polymerization obtain.Its softening temperature is greater than 140 ℃.Its molecular weight is from 200-20000, and suitable Poly Propylene Wax molecular weight is at 1000-8000, and optimum molecular weight ranges is 2000-6000.The softening temperature of Poly Propylene Wax is apparently higher than polyethylene wax, premium properties such as have high rigidity, the toughness oilness is good, wet fastness is good and the melt viscosity range of choice is wide, and high-crystallinity makes it to have remarkable brightness and glossiness.Poly Propylene Wax can be used for pigment dispersing agent, plastics additive, hot melt adhesive, easer, paper conversion auxiliary agent, rubber processing aids of paraffin modification agent, Masterbatch etc.
Ethylene bis stearamide of the present invention (N, N-Ethylene bis-Steramide) is a kind of good plastics lubricant, is called for short EBS.Molecular formula is C
