Description

A kind of PE-RT tubing special color masterbatch and preparation method thereof
Technical field
The present invention relates to the preparation field of plastics, especially a kind of PE-RT tubing special color masterbatch and preparation method thereof.
Background technology
PE-RT tubing, it is heat-resisting polyethylene tube, it is the english abbreviation of Polyethylene of raised temperature resistance pipe, be a kind of can be for the noncrosslinking polyethylene tube of hot water, also someone has given prominence to its noncrosslinking characteristic, be its " PE-RT Pipe ", be mainly used as the laying of floor heating heating pipe line.
PE-RT is a kind of a kind of medium-density polyethylene that adopts special molecular designing and synthesis technique to produce, and it adopts the method for ethene and octene copolymer, by controlling the quantity of side chain and distributing, obtains unique molecular structure, improves the thermotolerance of PE pipe.When using common colour batch to dye, because common look mother's fusing point is very low, its softening temperature and fusing point are very approaching, and under melt temperature, it does not almost have elastomeric state, is difficult to thermal stretch.And after reaching melt temperature, extensional viscosity sharply declines again, can be sagging rapidly under the combined action of gravity and thermal expansion.Prior art does not also have a kind of colour batch that can not can affect PE-RT forming tubular product and can not reduce the tensile strength of PE-RT tubing.
Summary of the invention
Object of the present invention is exactly overcome the deficiency of existing colour batch and a kind of PE-RT tubing special color masterbatch and preparation method thereof is provided.
For achieving the above object, technical scheme of the present invention is as follows:
A PE-RT tubing special color masterbatch, the weight percent of each component is: pigment 5-40%, dispersion agent 6-10%, coupling agent 0.5-2%, vector resin HDPE 10-30%, vector resin LDPE 10-30%, water-ground limestone 10-30%.
Pigment is mainly used in preparing the required color of colour batch, mainly comprises titanium dioxide, carbon black, various organic and mineral dye etc., can choose one or more according to the color of tubing and be used in conjunction with.
Dispersion agent is polyethylene wax.Polyethylene wax is the little microballon shape/chip solid of a kind of white, claims again macromolecule wax.Its density is 0.96-0.98g/cm3, the about 92 degrees Celsius of left and right of fusing point, and molecular weight 2000-5000, is formed by vinyl polymerization Rubber processing agent.Different according to preparation method, be divided into two kinds of waxes of cracking wax and synthetic wax.In this dedicated parent material, as dispersion agent and lubricant, use, can improve the dispersiveness of pigment, avoid occurring in use " color dot " that do not disperse, but also can add man-hour at tubing, there is good inside and outside lubrication, can improve processing characteristics, surface luster property, oilness and the thermostability of PE-RT tubing.
Coupling agent is a kind of a kind of plastics additive that improves the interface performance of synthetic resins and inorganic filler or strongthener, claims again surface-modifying agent.In PE-RT tubing special color masterbatch production process, can reduce the melt viscosity of synthetic resins, improve the dispersity of weighting agent to improve processing characteristics, reduce the production cost of masterbatch.And then obtain good surface quality and tensile strength in PE-RT tubing production process.Coupling agent refers to a class material that can improve interfacial characteristics between filler and macromolecular material.There is Liang Zhong functional group in its molecular structure kind: a kind of functional group can with macromolecule matrix generation chemical reaction or the consistency having had at least; Another kind of functional group can form chemical bond with mineral filler.Coupling agent can improve the interface performance between macromolecular material and filler, improves the binding property at interface, improves the performance of the macromolecular material after filling or enhancing, claims again surface-modifying agent.It is mainly divided into silane coupling agent, titanate coupling agent, aluminate coupling agent, organic chromium complex coupling agent and several classes of other types coupling agent.It can reduce the viscosity of molten synthetic resin in process of production, improves the dispersity of weighting agent to improve processing characteristics.And then make Polywoven Bag obtain good surface quality and tensile property.The present invention mainly selects one or more in first three kind coupling agent.
Vector resin HDPE is high density polyethylene(HDPE), claim again low pressure polyethylene, that a kind of degree of crystallinity is high, nonpolar, nontoxic, tasteless, the white particle of odorless, fusing point is 130 degrees Celsius, relative density is 0.946-0.976g/cm3, and degree of crystallinity is 80%-90%, and softening temperature is 125-135 degree Celsius, use temperature can reach 100 degrees Celsius, has good thermotolerance and winter hardiness.Its products machinery intensity is good, and environmental stress crack resistance is also better.Therefore use HDPE can effectively prevent from occurring in PE-RT tubing production process " heat is hung down " phenomenon as the carrier of PE-RT tubing special color masterbatch, improve rigidity and the toughness of PE-RT tubing.
Vector resin LDPE is low density Low Density Polyethylene, claiming again high-pressure polyethylene, is a kind of thermoplastic material, is that ethene and a small amount of higher alkene are under catalyst action, a kind of multipolymer forming through high pressure or low-pressure polymerization, its density is between 0.915-0.940g/cm3.Hot workability is good, and its fusing point is 120-125 degree Celsius, and melt flow index is higher, therefore can affect the processibility of PE-RT tubing, can produce " heat is hung down " phenomenon, but good with the consistency of PE-RT material, when producing, PE-RT tubing special color masterbatch is easy to processing.
Water-ground limestone, its relative molecular weight is 100.09, white powder, colourless, tasteless, stable in the air, water-soluble hardly, being insoluble to alcohol, is to be formed as calcite, marble, Wingdale grind by natural carbonate mineral, is conventional powder mineral filler.Adding the object of this component is weighting agent, reduces production costs.
The preparation method of this PE-RT tubing special color masterbatch: first each compositions in weight percentage is accurately weighed, load weighted material is placed in to high-speed mixer and carries out high-speed mixing, emit to mixing of materials to complete coated state, treat that cooling being placed in twin screw extruder of material extrude, granulation, packing makes finished product.
Beneficial effect of the present invention: the present invention adopts high density polyethylene(HDPE) to improve the processing characteristics of PE-RT tubing as carrier, prevents " heat is hung down " phenomenon producing in the PE-RT tubing course of processing.And can effectively improve tensile strength and the environmental stress crack resistance of PE-RT tubing, adopt simultaneously Low Density Polyethylene improve PE-RT tubing special color masterbatch processing characteristics and with the consistency of PE-RT tubing.Thereby reach the requirement that PE-RT tubing is produced, be difficult for producing " heat is hung down " phenomenon, and add this look imperial mother and do not affect PE-RT tubing mechanical property.
