Description
Technical field
The invention belongs to coloring plastic technical field, be specifically related to highlighted black masterbatch of a kind of high light and preparation method thereof.
Background technology
In the painted processing of engineering plastics, common technique be use toner (as carbon powder) in proportion directly with engineering plastics mixing extruding pelletization, or be injection molded into goods.There is bad dispersibility because toner is directly painted, measure inaccurate problem, can cause processed plastic product surface gloss poor, batch between there is the phenomenons such as aberration is serious; And due to dust when toner uses large, production plant environmental pollution can be caused serious.
In recent years, it is painted more and more general that use colour batch replaces toner to carry out, and the application of colour batch is more and more extensive, and the research and development of colour batch product innovation have become Plastics Processing Industry important technology field with production.The technological development direction of colour batch is devoted to matching and the compatibility of pigment, dispersion agent and carrier all the time, to improve the dispersiveness of pigment in masterbatch and concentration.Improve the concentration of pigment in colour batch, then the colour batch addition reached required for identical depth of shade can correspondingly reduce, but in colour batch, the concentration of pigment is higher, is more difficult to control pigment and reaches excellent dispersing property.
Black masterbatch uses comparatively extensive, and colour batch output about more than 40% is all black masterbatch.The main black pigment of black masterbatch and carrier, dispersion agent etc. are mixed.Some patent application documents or granted patent is had to disclose the technology adopting carbon black to prepare black masterbatch at present.Be the polyethylene tube carbonarius masterbatch of carrier as patent CN201010550637.X discloses with ultrahigh molecular weight polyethylene(UHMWPE); Patent CN200810029614.7 disclose with AS be carrier for AS serial plastic black agglomerate; These black masterbatch dispersing propertys are better, but existence needs are resin dedicated, range of application is little, or black pigment complicated component, the problems such as cost is higher.
Carbon black, as the pigment of black masterbatch, has that cost is low, wide feature of originating, but is not easy dispersion due to carbon black, and currently available technology adopts carbon black to be that the black masterbatch of raw material exists blackness, glossiness is difficult to the problem that improves.As CN1487018 discloses a kind of black agglomerate technology being exclusively used in styrene resin, be made up of carbon black, dispersed lubricant, vector resin.Each component is first carried out pre-mixing by preparation method in proportion, then mediates in high-speed kneading machine, is finally added in twin screw extruder by the compound fully mediated and extrudes, and makes required masterbatch through cooling, oven dry, pelletizing.Because carbon black dispersion is poor, adopt preparation method in this art solutions, be difficult to improve content of carbon black, cause being difficult to improve blackness again, can not meet current technology, cost needs.
Summary of the invention
In order to overcome the shortcoming of prior art with not enough, primary and foremost purpose of the present invention is to provide a kind of highlighted black masterbatch of high light with high, the easy dispersion of concentration;
Another object of the present invention is to the preparation method that the highlighted black masterbatch of above-mentioned high light is provided; By preferably arranging in pairs or groups to the design parameter of technique each in preparation method, obtaining a kind of preparation method improving carbon black dispersion performance, improve black masterbatch gloss blackness, the effect that current existing technology of preparing is difficult to realize can be reached, there is obvious technical superiority.
Object of the present invention is achieved through the following technical solutions:
The highlighted black masterbatch of a kind of high light, the weight percent of its each component is:
Described carbon black, except as except dyeing pigment, also has the effect of UV light stabilizing agent, can effectively prevent plastics to be subject to solar radiation and produce light ammonification and degrade, thus improves quality and the work-ing life of plastics;
Described vector resin adds the resinous type of the identical or similar nature of engineering plastics kind corresponding selection of application according to the highlighted black masterbatch of high light, be specially more than one in acrylonitritrile-styrene resin (AS), polystyrene resin (PS), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), acrylic resin (PP), polyamide resin (PA), polyethylene terephthalate (PET) or polyvinyl resin (PE);
Preferably, described hyper-dispersant is ethylene bis stearic acid amide;
Preferably, described high-temperature stabiliser is polyethylene wax or polyester wax; High-temperature stabiliser is the dispersing property in order to keep component in preparation process, and preparation technology is generally hot-work, and therefore high-temperature stabiliser needs resistance to elevated temperatures, preferably has more than 400 DEG C durothermic high-temperature stabilisers;
The highlighted black masterbatch of above-mentioned high light, the preferred weight percent of its each component is:
The preparation method of the highlighted black masterbatch of above-mentioned high light, comprises the steps: carbon black, vector resin, hyper-dispersant and high-temperature stabiliser to prepare by formulation content, is all added by each feed composition in low-speed mixer and carry out pre-mixing process 3 ~ 5min; Then gained mixture is moved into pressurization internal mixer, in 8 ~ 10kg pressure, pressurize at 80 ~ 120 DEG C banburying 12 ~ 15min; The banburying gained material that will pressurize is cut into slices, and put into two roll press and carry out extrusion molding, control roller surface temperature is 80 ~ 100 DEG C, and temperature of charge is 150 ~ 180 DEG C; Extruding gained material is carried out fragmentation, and then move in spiral tablets press and carry out granulation, the screw speed of spiral tablets press is 450r/min, and die head temperature is 180 ~ 200 DEG C, and stock cutter rotating speed is 800 ~ 1100r/min; By gains grain through cooling, dry, packing, obtain the highlighted black masterbatch of described high light;
Preferably, the machine barrel outer setting of spiral tablets press has multiple stage heater, and arranging front-end temperature is 220 ~ 230 DEG C, and stage casing temperature is 180 ~ 200 DEG C, and back segment temperature is 160 ~ 180 DEG C.
The present invention has following advantage and effect relative to prior art:
(1) content of carbon black of the highlighted black masterbatch of high light of preparation method's gained of the present invention is high, and blackness is high, greatly can save the cost of coloring plastic processing.
