Abstract
The invention discloses a preparation method of permanent red S2BL. The method comprises the steps that: 2B acid and liquid alkali are dissolved until an obtained solution is transparent; ice is added for cooling the solution; hydrochloric acid is added for acid precipitation; a sodium nitrite solution is added to the material, the mixture is stirred for 1h, and an obtained material is preserved for later use; naphthol AS-OL and liquid alkali are dissolved in a dissolving kettle, until an obtained solution is transparent; the solution is placed in a coupling kettle; temperature and volume are adjusted; a diazo solution is added for coupling; when coupling is finished, dissolved rosin soap is added; barium chloride is added for color lake according to a process time; the material is washed in a press-filter; a filter cake is dried by baking, and is grinded into powder; and the powder is packaged, such that finished products are obtained. With the permanent red S2BL preparation method provided by the invention, the produced product is advantaged in good dispersity and low viscosity. With the method, labor wasting during the production process is avoided, and the service life of the pigment is prolonged.
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 permanent bordeaux S2BL.
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 performance requriements of pigment is also increasingly high, and dispersed and viscosity are wherein to judge two of important indicator that pigment mass is fine or not.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method for preparing the lower and dispersed S2BL of permanent bordeaux preferably of viscosity.
The present invention solves the scheme that its technical problem takes: the preparation method of a kind of permanent bordeaux S2BL, 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 Naphthol AS-OL in dissolution kettle, add liquid caustic soda then and make temperature rise to 85 ℃, it is dissolved to puts into the coupling still after transparent; Adjustment coupling temperature is 10 ℃; The coupling volume is 20 times of coupling component, adds above-mentioned steps c again and gives over to subsequent use diazonium liquor and carry out coupling, and coupling finishes; Stirred 30 minutes, adjusting pH value then is 9.5;
E. add the good rosined soap of dissolving, the adjustment pH value is to 9.5-10, and rising to the color lake technological temperature is 80 ℃;
F. add bariumchloride 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 product dispersiveness that the preparation method produced of permanent bordeaux S2BL provided by the invention has better been avoided the manual work waste in the production process, and the product viscosity height has prolonged the work-ing life of pigment.
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 permanent bordeaux S2BL of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing and embodiment:
The preparation method of a kind of permanent bordeaux S2BL 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 Naphthol AS-OL in dissolution kettle, add liquid caustic soda then and make temperature rise to 85 ℃, it is dissolved to puts into the coupling still after transparent; Adjustment coupling temperature is 10 ℃; The coupling volume is 20 times of coupling component, adds to give over to subsequent use diazonium liquor and carry out coupling again, and coupling finishes; Stirred 30 minutes, adjusting pH value then is 9.5; Add the good rosined soap of dissolving, the adjustment pH value is to 9.5-10, and rising to the color lake technological temperature is 80 ℃; Add bariumchloride 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 product that the preparation method produced of permanent bordeaux S2BL provided by the invention is better dispersed, has avoided the manual work waste in the production process, and the product viscosity height has prolonged the work-ing life of pigment.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
