Abstract
A manufacture process for inflation film grade universal color master-particles with high content and coloring capability features that polyethylene and inorganic pigment as main raw materials and monglyceride stearate and low-molecular polyvinyl wax as disperser and surface modifier pass through smelting, mixing, dispersing, and then extruding and granulating. Its advantages are high pigment content, high colouring capability, high dispersity of pigment in plastics and low cost.
Description
Technical field:
The present invention relates to a kind of high-content, high tinting strength, the general Masterbatch of blown film level plastics.
Along with the development of society, the application of plastics has been penetrated into fields of society.Plastics by the mineral dye with different colours, can give plastics colourful outward appearance easily by inorganic pigment coloring, and this is the most significant aspect that it is better than traditional material goods (such as steel, iron and stone product).
Plastics are macromolecule organic materials, the affinity of it and mineral dye is very poor, if mineral dye is not carried out pre-treatment, the mineral dye that particle is very thin is difficult to be uniformly dispersed in plastic body, cause plastics painted inhomogeneous, influenced the visual appearance and the work-ing life of goods.In order to improve dispersiveness and the tint permanence of pigment in plastic body, adopt some processing aids to anticipate the mineral dye surface at present, improve the compatible affinity of pigment and plastics, mix with a spot of certain plastics to extrude and make the Masterbatch of plastics with the high density pigment content, next painted with the plastic color master grain in the processing of plastics, improve plastics uniform coloring degree and visual appearance.At present, people generally adopt tung oil or some the low-molecular-weight paraffin surface treatment agent as pigment, but these treatment agents are unsatisfactory in the dispersive ability of plastic body to pigment, and particularly in some plastic membrane blowing goods, coloration efficiency and homogeneity all do not reach specification of quality.
Summary of the invention:
The purpose of this invention is to provide a kind of high-content, high tinting strength, the manufacture method of the general Masterbatch of blown film level plastics, the present invention utilizes low-molecular-weight polyethylene wax that reasonable characteristic of the adsorptivity of mineral dye and stearic acid Tegin 55G are had efficient lubrication characteristic to plastic molecules, at first handle mineral dye with low-molecular-weight polyethylene wax and stearic acid Tegin 55G, improve the affinity and the dispersiveness of mineral dye and plastics, melt extrude granulation with a spot of polyethylene again, make high-content, the high-strength high-grade Masterbatch that can be used for the blown film plastics, this Masterbatch is in the plastics coloring process, has the coloration efficiency height, consumption is few, high and the low advantage of cost of uniform coloring degree is for the plastic working industry provides a kind of new high-quality color master-batch product.
This plastic color master grain prepares by following steps: (1) mixes mineral dye and a spot of polyethylene, a certain amount of low molecular weight polyethylene wax, a certain amount of stearic acid Tegin 55G in mixing machine, at 100-150 ℃, grind fully then with shredder.(2) ground pigment matrix is carried out fragmentation, with a certain amount of polyethylene thorough mixing.(3) at 160-200 ℃, use the plastics extruder extruding pelletization, make the blown film level plastics general Masterbatch of mineral dye weight content at 5%-40%.
Advantage of the present invention is that preparation technology is simple and easy to control, and preparation process does not have waste water, waste gas produces.The plastic color master grain of the present invention's preparation can be used for the painted of various plastic injection-moulded goods and blown film goods, and cost is at 6000 yuan/ton, and coloration efficiency is higher 2 times than Similar colour master batch on the market, is a high quality plastic color master grain.
