Abstract
The production process of colorant includes the following steps: 1). uniformly stirring polyethylene wax and color powder or filler; 2). cooling and caking; 3). pulverizing; and 4). extruding and granulating. The above-mentioned color powder can be organic one, also can be inorganic one. Said colorant has good dispersibility in plastics, and its production cost is low.
Description
1, technical field:
The present invention is a kind of production technique of Masterbatch, belongs to the innovative technology of Masterbatch production technique.
2, background technology:
At present China's Masterbatch technology of producing is to carry out putting the forcing machine extruding pelletization into after the high-speed stirring with molecular wax, plastic pellet or synthetic resin moulding compound and toner or stopping composition to form, because these materials begin to stir temperature just, therefore, plastics and molecular wax are difficult to coat each toner particle or stopping composition particle.The Masterbatch that this explained hereafter is come out is bad dispersibility in use, and there is the scar grain on the Masterbatch surface.For this reason, some producer uses other auxiliary agents, having coated each toner particle or filler grain, but needs cost a large amount of electric power energy and man-hour, causes the waste in the electricity charge and man-hour, has both increased production cost, has prolonged the production time again, the production efficiency of reduction.
3, summary of the invention:
The objective of the invention is to consider the problems referred to above and provide a kind of not only can reduce production costs, can shorten the production time again, the production technique of the Masterbatch of enhancing productivity.The Masterbatch of producing with production technique of the present invention is good dispersity in use, and the Masterbatch surface does not have the scar grain.
The production technique of Masterbatch of the present invention includes following steps:
1) polyethylene wax and toner or stopping composition are stirred;
2) cooling caking;
3) fragmentation;
4) extruding pelletization.
Above-mentioned steps 1) temperature of polyethylene wax can be 120 ℃～300 ℃ in.
Above-mentioned steps 2) adopts naturally cooling.
Above-mentioned steps 2) the naturally cooling time can be 20～40 minutes.
Above-mentioned steps 4) the extruding pelletization process in adopts hot water to extrude.
Above-mentioned hot water temperature can be 100 ℃～160 ℃.
Above-mentioned toner can be organic toner, also can be inorganic toner.
The present invention is owing to adopt molecular melt wax and the toner material of organic or inorganic or the complete processing that stopping composition stirs coating, therefore, it can guarantee that molecular melt wax coats each toner particle or stopping composition fully, it is dispersed fabulous that its Masterbatch of producing is applied in the plastics, the no scar grain in surface.The present invention not only can reduce production costs, and can shorten the production time again, enhances productivity, and is the production technique of a kind of simple and convenient, with low cost Masterbatch.
4, embodiment:
Embodiment:
The production technique of Masterbatch of the present invention includes following steps:
1) polyethylene wax and toner or stopping composition are stirred;
2) cooling caking;
3) fragmentation;
4) extruding pelletization.
Above-mentioned steps 1) polyethylene wax in obtains by the polyethylene cracking, and its temperature can be 120 ℃～300 ℃.The time that polyethylene wax and toner or stopping composition stir can be 30 seconds～and 30 minutes, decide according to what of concrete material and material, stir to guarantee material.Above-mentioned steps 2) adopt naturally cooling, the time can be 20～40 minutes, and in the present embodiment, the time of naturally cooling is 30 minutes.
Above-mentioned steps 4) the extruding pelletization process in adopts hot water to extrude, and the hot water temperature can be 100 ℃～160 ℃.In the present embodiment, the hot water temperature is 120 ℃.
Above-mentioned steps 1) toner in can be various natural colored raw materials, can be organic toner, also can be inorganic toner, and as carbon black, titanium dioxide etc., stopping composition can be lime carbonate, kaolin, talcum powder etc.
