Therefore, the grinding aid which has high grinding efficiency, low energy consumption and low cost is urgently needed to be developed.
In addition, the crushing of the raw materials is an essential working procedure in the preparation process of the ceramics, and the crushing is an operation process with high energy consumption and low efficiency. The ceramic forming slurry has the characteristics of slurry raw materials, clay, fluxes (potash feldspar and talc) and quartz hard materials, the ceramic forming slurry raw materials are various, the particle size difference of the materials is large, the texture hardness difference is large, how to ensure that clay fine-diameter materials are not ground to be too small in particle size in the wet grinding process for several hours, the requirement standard of slurry particle grading is met, how to quickly loosen the clay materials, the clay fine-diameter materials are suspended after a short time, the expansion of the microcracks of the hard materials is promoted, the hard materials actually have inherent microcracks, the hard materials generate the formation of new microcracks at any time in collision with a grinding medium and friction of other materials in a ball mill, the distribution of the microcracks is irregular, the average distance between the microcracks is 10-100 nm, and the fine grinding process of solids is the formation and expansion process of the microcracks. Therefore, the technical problems to be solved by the technicians in the field are to reduce the formation and expansion of micro cracks in the fine crushing process of the solid and to improve the qualification rate of semi-finished products and finished products.
Disclosure of Invention
The invention provides a ceramic slurry ball-milling grinding aid and a ball-milling process, and solves the problems of low grinding aid efficiency, high cost, high slurry preparation energy consumption and low finished product qualification rate of the grinding aid in the related technology.
The technical scheme of the invention is as follows:
the ceramic slurry ball-milling grinding aid comprises the following components in parts by weight: 25-35 parts of additive, 5-10 parts of surfactant, 10-15 parts of thickener and 55-65 parts of water;
the additive comprises 3-amino-N- (2-mercaptoethyl) propionamide and 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride.
3-amino-N- (2-mercaptoethyl) propionamide CAS number: 539-83-3,1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride CAS number: 7084-11-9.
As a further technical proposal, the mass ratio of the 3-amino-N- (2-mercaptoethyl) propionamide to the 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride is (4-6): 1.
As a further technical scheme, the surfactant comprises one or more of sodium dodecyl benzene sulfonate, sodium dodecyl sulfate and glyceryl monostearate.
As a further technical solution, the thickener comprises one or more of hydroxypropyl methylcellulose and hydroxyethyl cellulose.
The invention also provides a preparation method of the ceramic slurry ball-milling grinding aid, which comprises the following steps:
s1, preparing raw materials in parts by weight;
s2, mixing water and a thickening agent, and uniformly stirring;
and S3, adding the additive and the surfactant, stirring and mixing to obtain the grinding aid.
A ball milling process of ceramic slurry comprises the following steps:
a1, preparing materials: 30-50 parts of potash feldspar, 20-30 parts of sericite, 15-30 parts of water-washed kaolin, 10-20 parts of black mud, 10-20 parts of clay, 10-20 parts of kaolin, 1-2 parts of water glass, 0.1-0.5 part of soda ash, 40-50 parts of water and 0.5-1.0 part of grinding aid;
a2, adding 1/2 of water, potash feldspar, sericite, clay, water glass and soda ash into a ball mill, and carrying out primary ball milling to obtain primary slurry;
and A3, putting the primary slurry and the rest raw materials into a ball mill, and carrying out secondary ball milling to obtain secondary slurry.
As a further technical scheme, the water is hot water with the temperature of 60-65 ℃.
As a further technical scheme, the time of one-time ball milling in A2 is 5h.
As a further technical scheme, the secondary ball milling time in the step A3 is 30-60 min.
The working principle and the beneficial effects of the invention are as follows:
1. according to the invention, 3-amino-N- (2-mercaptoethyl) propionamide and 1- (3-dimethylaminopropyl) -3-ethyl carbodiimide hydrochloride are mixed and used as additives in the grinding aid, so that the grinding aid efficiency of the grinding aid is improved. On one hand, the mass ratio of 3-amino-N- (2-mercaptoethyl) propionamide to 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride is controlled in the range of (4-6): 1, the grinding efficiency improvement rate of the grinding aid is over 75.8%, and the grinding aid has the best grinding efficiency; on the other hand, the 3-amino-N- (2-mercaptoethyl) propionamide and the 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride are mixed for use, have a synergistic effect, and remarkably improve the grinding aid efficiency of the grinding aid.

Sieving the secondary slurry obtained in the examples 1-6 and the comparative examples 1-3 by using a 200-mesh sieve, weighing the dried sieve residue, and testing the grinding efficiency improvement rate of the grinding aid:
the grinding efficiency improvement (%) = (remaining sieve with no grinding aid added-remaining sieve with grinding aid added)/remaining sieve with no grinding aid added × 100, and the test results are reported in table 1.
TABLE 1 grinding aid Performance test results
As can be seen from Table 1, the grinding aid provided in examples 1-6 of the present invention has a grinding efficiency improvement rate of 74.9% or more and a high grinding aid efficiency, and since example 4 does not use hot water at 60-65 ℃ in the ball milling process, the grinding efficiency improvement rate is lower than that of example 5, since the grinding aid in example 5 comprises 3-amino-N- (2-mercaptoethyl) propionamide and 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride in a mass ratio of 3 to 1, the grinding aid in example 6 comprises 3-amino-N- (2-mercaptoethyl) propionamide and 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride in a mass ratio of 7.
Compared with the grinding aid prepared in the embodiment 1, the grinding efficiency improvement rate of the grinding aid prepared by the method is greatly reduced, and the grinding efficiency improvement rates of the grinding aids prepared in the comparative examples 1 and 3 are compared with that of the grinding aid prepared in the embodiment 1, namely the 3-amino-N- (2-mercaptoethyl) propionamide and the 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride are mixed for use, so that the synergistic effect is achieved, and the grinding efficiency of the grinding aid is remarkably improved.
In order to investigate the influence of hot water on the ball milling process, ball milling time tests are performed on the embodiment 1 and the embodiment 4, the slurry provided by the embodiment 1 and the embodiment 4 is used for producing the fully-enclosed conjoined toilet according to GB6952-2005, the qualification rate of finished products is tested, all indexes meet the requirements, and the analysis results are recorded in Table 2.
TABLE 2 ball milling time and product percent of pass
| Example 1 | Example 4 | |
| Ball milling time/h | 5.5 | 7.5 |
| Percent of pass/percent of finished product | 94.5 | 90.1 |
As can be seen from table 2, the ball milling process described in example 1 of the present invention achieves a final product yield of 94.5%, since example 4 uses hot water at a temperature of not 60 to 65 ℃ during the ball milling process, the final product yield is only 90.1%, and in addition, the ball milling time of example 1 is shortened by 2 hours by using hot water injection compared with that of example 4 by adding normal temperature water injection.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
