The lubricating master batch for plastic processing is prepared to spherical, columnar particles and the like by virtue of extrusion and prilling. The lubricating master batch for plastic processing can be used as a lubricant for modifying and processing a macromolecular material and is convenient to add and accurate to meter, uniformly to mix in kneading process and convenient in effect taking during a process of modifying and processing a macromolecular material.
Description
Technical field
The present invention relates to field of high polymer material processing, be specially lubricated master batch and preparation method thereof for a kind of plastic working.
Background technology
The development of macromolecular material is advanced by leaps and bounds in recent decades, and the processing modified of macromolecular material grows up in order to meet the particular requirements such as automobile, electrical equipment, communication, high-grade instrument.Single macromolecular material is often because certain some defect is difficult to meet the demands.And will make its performance increase substantially by carrying out modification with other macromolecular materials or packing material, meet different requirements.
And in the processing modified process of macromolecular material, need different processing aids to coordinate, wherein lubricant is exactly very important one.The Main Function of lubricant is exactly the friction reducing in the course of processing between macromolecular material and processor surface, macromolecular material interior molecules, thereby improves its processibility, and improves the performance of macromolecular material.Lubricant mainly contains hydro carbons (as paraffin), aliphatic acid (as stearic acid) and acid amides are (as stearic amide, N, the higher stearic amide of fusing point of N-ethylene bis stearic acid amide and modification), ester class (as Chinese wax, stearate) and salt (stearate), higher alcohols (C18 alcohol, C16 alcohol), low-molecular-weight polyolefin (polyethylene wax, oxidized polyethlene wax), organosilicon (silicone oil, silicone) etc.From lubricant role, can be divided into again internal lubricant, external lubricant or early stage lubricant, later stage lubricant.Therefore in use in order to keep lubrication balance, often need multiple lubricant compound use.
Most lubricants are all powderies, and most resin particle is circular or oval, and the amount of lubricant accounts for a little part in plastic composite.Therefore in the course of processing, powder can spill between the gap of particle, causes inhomogeneous.Not only cannot better bring into play the effect of lubricant, and local too much, the detrimentally affect such as also can cause that lubricant is separated out.
Plastic master batch is widespread use in plastic working modification, and as Masterbatch, fire-retardant master granule, filling master batch and other functional agglomerates, but lubricated master batch research is few.
Patent CN103044740A introduces the lubricated master batch of a kind of filling plastic, and the lubricated master batch of this invention filling plastic is by 100 parts of inorganic powders by mass, 20～100 parts of lubricants, 1～5 lubrication assistant dispersion agent, 0.1～3 part of coupling agent, the vector resin of 5～30 parts, 0～2 part of compound particle that forms of functional agent.This patent is preferred by raw material, by compound to sheet and spherical inorganic powder, coordinate again other components, the packing lubrication master batch forming has good oilness and fills increment effect in plastic working, have toughness reinforcing enhancing concurrently, increase the effects such as glossiness, reach the object that packing lubrication unites two into one, be conducive to simplify plastic formula and technique, improve plastics over-all properties, reduce production costs.But the main object of this patent is as filling master batch, so filler accounts for the overwhelming majority, and oilness is an auxiliary function.
Summary of the invention
The invention provides lubricated master batch and preparation method thereof for a kind of plastic working, this masterbatch melts finger vector resin with height, be used for wrapping up one or several lubricants, suitably add other compositions and processing aid, then mix, utilize Banbury mixer, screw extrusion press etc. to carry out granulation, obtain lubricated master batch.The benefit of this lubricated master batch is good and resin particle mixes, and better brings into play its effect.
Lubricant can be hydro carbons (as paraffin), aliphatic acid (as stearic acid) and acid amides are (as stearic amide, N, the higher stearic amide of fusing point of N-ethylene bis stearic acid amide and modification), ester class (as Chinese wax, stearate) and salt (stearate), higher alcohols (C18 alcohol, C16 alcohol), low-molecular-weight polyolefin (polyethylene wax, oxidized polyethlene wax), organosilicon (silicone oil, silicone) etc.For the lower polyolefine of processing temperature, can select the lubricant that fusing point is lower.And the higher engineering plastics of processing temperature need to be selected the higher lubricant of fusing point.And in actual use, need the composite use of multiple lubricant.The polyolefine such as EVA, POE, PE, PP that can adopt for the lubricant using in polyolefine material, as vector resin, is prepared lubricated master batch.Select to refer to be chosen in 5-50 as polyolefinic the melting of vector resin, the material referring at 20-30 is melted in preferential selection.Can adopt high PS, the PA etc. that melts finger as vector resin for the lubricant using in engineering plastics, prepare lubricated master batch.Select to refer to be chosen in 5-50 as PS, ABS, the melting of PA of vector resin, the material referring at 10-20 is melted in preferential selection.And for needing heating adding of lubricated master batch, therefore add a certain amount of oxidation inhibitor.Oxidation inhibitor can be selected conventional oxidation inhibitor and combination, preferential 1010 or 168 and combination.For the lower material of intensity, can add a small amount of filler, filler is preferentially selected talcum powder.
Technical scheme of the present invention, provides lubricated master batch and preparation method thereof for a kind of plastic working, is wherein made up of vector resin, lubricant compositions, oxidation inhibitor.Vector resin is to melt polyolefine, PS, the PA etc. that finger is higher, and Lubrication Composition is multiple lubricant compositions, and oxidation inhibitor is one or more compositions.Vector resin in lubricated master batch: Lubrication Composition: oxidation inhibitor is (10～40): (50～70): (1～10).
