Abstract
The invention discloses a preparation method of 3118 sun-proof bright-red BBN. The method comprises the steps that: 2B acid and liquid alkali are dissolved in a dissolving kettle, until an obtained solution is transparent; ice is added for cooling the solution; hydrochloric acid is added for acid precipitation; a sodium nitrite solution and ice blocks are added to the material, the mixture is stirred for 1h, and an obtained material is preserved for later use; 2, 3 acids, liquid alkali, and water 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 3118 sun-proof bright-red BBN preparation method provided by the invention, the dispersity of the produced product is good. With the method, labor wasting and high energy consumption during plastic and EVA production processes are avoided, and filament breakage phenomena during a chemical fiber spray-spinning process are reduced.

Summary of the invention
It is dispersed strong that technical problem to be solved by this invention provides a kind of preparation, and the heatproof temperature tolerance better and reduce the method for 3118 light-resistant scarlet BBNs of wire broken rate.
The present invention solves the scheme that its technical problem takes: a kind of preparation method of 3118 light-resistant scarlet BBNs, 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 and water then and make temperature rise to 60 ℃; It is dissolved to puts into the coupling still after transparent, add and give over to subsequent use diazonium liquor among the said step c 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;
E. add the good rosined soap of dissolving, the adjustment pH value is warming up to 78 ℃-83 ℃ of technology color lake temperature to 9.5-10;
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 preparation method of 3118 light-resistant scarlet BBNs provided by the invention reduces temperature of reaction according to doazo reaction characteristics and temperature; Make product yield promote 3.63%; Change adjustment crystalline structure through temperature improves dispersiveness and temperature tolerance, in polyster fibre, uses; Can reduce wire broken rate more than 3.2%, reduce the loss of artificial waste and energy.
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's 3118 light-resistant scarlet BBNs.
Embodiment
Describe the present invention below in conjunction with accompanying drawing and embodiment:
The preparation method of a kind of 3118 light-resistant scarlet BBNs 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 ℃; It is dissolved to puts 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 is warming up to 78 ℃-83 ℃ of technology color lake temperature to 9.5-10; 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.10gBBN adds tree grease and high-boiling point kerosene 40g altogether, grinds through three-roller, and through emulsification instrument emulsification, PH does not have drift and through adding macromolecule resin, makes thermotolerance be increased to 240 ℃ with ground material, in the EVA foaming, test 10 minutes colour-fast.The preparation method of 3118 light-resistant scarlet BBNs provided by the invention reduces temperature of reaction according to doazo reaction characteristics and temperature; Make product yield promote 3.63%; Change adjustment crystalline structure through temperature improves dispersiveness and temperature tolerance, in polyster fibre, uses; Can reduce wire broken rate more than 3.2%, reduce the loss of artificial waste and energy.
