Performance detection
The inks obtained in examples 1 to 14 and comparative example 1 were tested for their properties according to GB/T14624.3-1993 "test method for ink fluidity", and the larger the value of the obtained flow value (mm), the better the fluidity;
the inks obtained in examples 1 to 14 and comparative example 1 were tested for properties according to GB/T14624.5 "ink viscosity test method", the greater the value of viscosity (Pa.s) obtained, the more viscous the ink;
QB 570-1983 ink fixation speed test methods (A) and (B) the inks obtained in examples 1 to 14 and comparative example 1 were tested for their performance, the smaller the fixation speed, i.e., the shorter the initial drying time of the ink, the better the drying properties of the ink;
GB/T14624.4 ink film drying test method for testing the performance of the ink obtained in examples 1-14 and comparative example 1, the smaller the film drying time, the shorter the time for changing the ink thin layer surface from slurry state to solid state, and the better the ink drying performance.
The drying of the ink is carried out in two stages, namely fixing and drying of the film. The ink is changed from liquid state to semi-solid state and can not flow and transfer any more, which is the fixation stage of the ink, namely the initial drying of the ink; the vehicle in the semi-solid ink has physical and chemical reactions and is completely dried and solidified into a film, which is the complete drying stage of the ink. The sum of the drying time of the film and the fixing speed is the total drying time of the ink.
The results are shown in Table 1.
TABLE 1 ink test results Table
As can be seen from table 1, in examples 1 to 3, the fixing speed and the film-drying time were both large and the overall drying speed was slow in examples 1 and 3, compared to example 2, and the ink fixing speed and the film-drying time corresponding to example 2 were small, indicating that the drying was relatively fast, the viscosity and the flow value of example 2 were excellent, and the performance of example 2 was the most excellent, so the ratio corresponding to example 2 was the optimum ratio.
In examples 2 and 4 to 5, the viscosity, flow value and fixing speed of examples 2, 4 and 5 were almost unchanged, but the film-forming drying time of example 2 was the minimum, indicating that the ink was dried thoroughly at this weight ratio.
In examples 2 and 6 to 7, the viscosity and the flow value of example 6 were much lower and higher, which makes the obtained ink viscous, and thus ink mistaking was likely to occur, while the viscosity and the flow value of example 7 were much higher and lower, which makes the obtained ink viscous, and thus ink transfer was likely to be poor, and the viscosity and the flow value of example 2 were moderate, which makes the ink performance the most excellent, showing that the weight part ratio of soybean oil, isooctyl palmitate and palm oil in example 2 was the best.
In examples 2 and 8 to 9, the viscosity of the ink was slightly increased and the flow value was decreased in examples 8 to 9, but the change was small, and the fixing speed of the ink was increased in examples 8 to 9, which indicates that the drying property was decreased, and the ratio in example 2 was the most preferable.
In examples 2 and 10 to 14, the viscosity of example 11 was much lower and the flow value was much higher, and the ink obtained was more viscous and liable to cause ink misting, and it was explained that the safflower oil addition amount of example 11 may be too high to cause an excessive influence on the properties of the ink; the significantly lower fixing rates of the inks of examples 10-14 indicate that the addition of safflower oil increases the dry-out rate of the ink on eating feces, and the lower fixing rates of the inks of examples 12-14 indicate a faster initial drying rate, indicating that the ink vehicles and inks within the range of examples 12-14 have better performance, and the lowest fixing rate of the ink of example 13 indicates that the ratio of soybean oil to safflower oil is optimal, so the ratio of the raw materials of example 13 is optimal.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
