Abstract
The invention discloses a preparation method for 3120 light fast brilliant red BBC. The method comprises the following steps: dissolving 2B acid and liquid alkali until a transparent solution is obtained, cooling the solution with ice, adding hydrochloric acid for acidification, adding a sodium nitrite solution, carrying out stirring for one hour, leaving an obtained mixture for subsequent usage, dissolving 2,3-acid, liquid alkali and water in a dissolving kettle until a transparent solution is obtained, placing the obtained transparent solution into a coupling kettle, adjusting the temperature and the volume of the transparent solution, adding a liquid diazonium solution for coupling, adding dissolved rosin soap after coupling is finished, adding calcium chloride for laking according to process time, carrying out washing in a filter press, drying a filter cake and grinding and packaging the filter cake to obtain a product. The product prepared by using the preparation method for 3120 light fast brilliant red BBC provided in the invention has good dispersibility, which enables waste of labor and consumption of energy during production to be reduced.
Description
Technical field
The present invention relates to a kind of preparation method of pigment, specifically, relate to the preparation method of a kind of 3120 sun-proof bright red BBC.
Background technology
Along with the raising of people's lives demand, many places such as printing ink, coloured plastics material are all used pigment, and the requirement of pigment also is increasingly high, and dispersiveness is an important indicator wherein.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method for preparing 3120 strong sun-proof bright red BBC of dispersiveness.
The present invention solves the scheme that its technical problem takes: the preparation method of a kind of 3120 sun-proof bright red BBC, and this method may further comprise the steps:
A. 2B is sour, liquid caustic soda water is dissolved to transparent in dissolution kettle, and the technological temperature that is cooled on the rocks;
B. add hydrochloric acid and carry out acid out, acid out is to PH=0.5-1;
C. add sodium nitrite solution and ice cube, stirred 1 hour, give over to subsequent use;
D. add 2,3 acid in dissolution kettle, add liquid caustic soda then and make temperature rise to 60 ℃; Be dissolved to and put into the coupling still after transparent, add that step c is said to be given over to subsequent use diazonium liquor and carry out coupling again, adjustment coupling temperature is 10 ℃; The coupling volume is 20 times of coupling component; Coupling finishes, and stirs 30 minutes, and adjusting pH value then is 9.5;
E. add the good rosined soap of dissolving, the adjustment pH value to 9.5-10, be warming up to 78 ℃-80 ℃ of color lake technological temperatures;
F. add calcium chloride according to the process time and carry out the color lake, be stirred to the process time, again temperature is risen to technological temperature, be incubated according to processing requirement;
G. get into pressure filter press filtration, washing after insulation finishes, the filter cake oven dry is worn into powder threading row with it again be packaged to be the finished product.
As preferably, the technological temperature of said step a is 0 ℃-5 ℃.
As preferably, the technological temperature among the said step f is 60 ℃-95 ℃, and the process time is 40min-70min.
As preferably, the pressure of press filtration is 0.3MPa-0.6MPa in the said step g, and time of filter pressing is 3h-6h.
The invention has the beneficial effects as follows: the performance of the product that the preparation method the produced dispersiveness of 3120 sun-proof bright red BBC provided by the invention is than higher; Need be in plastics, EVA production process through repeatedly roller is experienced; Reduce the consumption of energy and reduced the artificial waste, avoided spray silk process to block the fracture of wire phenomenon of web plate.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is preparing method's process flow sheet of the present invention 3120 sun-proof bright red BBC.
Embodiment
Describe the present invention below in conjunction with accompanying drawing and embodiment:
The preparation method of a kind of 3120 sun-proof bright red BBC shown in Figure 1, this method may further comprise the steps: 2B is sour, liquid caustic soda water is dissolved to transparent in dissolution kettle, and the technological temperature (0 ℃-5 ℃) that is cooled on the rocks; Add hydrochloric acid and carry out acid out, acid out is to PH=0.5-1; Add sodium nitrite solution and ice cube, stirred 1 hour, give over to subsequent use; Add 2,3 acid in dissolution kettle, add liquid caustic soda and water then and make temperature rise to 60 ℃; Be dissolved to and put into the coupling still after transparent, add and give over to subsequent use diazonium liquor and carry out coupling, adjustment coupling temperature is 10 ℃; The coupling volume is 20 times of coupling component; Coupling finishes, and stirs 30 minutes, and adjusting pH value then is 9.5; Add the good rosined soap of dissolving, the adjustment pH value to 9.5-10, be warming up to 78 ℃-80 ℃ of color lake technological temperatures; Add calcium chloride according to the process time and carry out the color lake, be stirred to the process time (40min-70min), again temperature is risen to technological temperature (60 ℃-95 ℃), be incubated according to processing requirement; Be incubated the back that finishes and get into pressure filter press filtration (pressure is that 0.3MPa-0.6MPa, time of filter pressing are 3h-6h), washing, the filter cake oven dry is worn into powder threading row with it again be packaged to be the finished product.The 3120 sun-proof bright red BBC dispersing propertys that use this kind preparation method to make are good, as select the 120 sun-proof bright red BBC pigment of 200g3 for use, add the rubber base-material 40g for preparing; Mixing on two roller machines; Not having color spot to pigment only needs 35 times, and the K/S value of pigment in resin is 100%, need be through repeatedly roller is experienced in plastics, EVA production process; Reduce the consumption of energy and reduced the artificial waste, avoided spray silk process to block the fracture of wire phenomenon of web plate.
