Embodiment 1
[0043] A polyacrylate emulsion printing paste has been prepared, and the anti-sticking agent is added according to the following steps:
[0044] 1. According to the method in Table 1, it is judged that the viscosity of the printed product of the printing paste is grade 3.
[0045] 2. Select the anti-sticking agent composed of paraffin oil, mineral oil and silicone oil. The mass ratio is 6:3:1.
[0046] 3. Mix paraffin oil, mineral oil, and silicone oil in a mass ratio of 6:3:1, and mechanically stir to form a uniform mixture;
[0047] 4. While stirring the printing glue, slowly add the anti-sticking agent prepared according to step 3, whose quality is equivalent to 3.0% of the printing glue, and continue stirring until the glue is evenly mixed.
Embodiment 2
[0061] A polyacrylate emulsion printing paste has been prepared, and the anti-sticking agent is added according to the following steps:
[0062] 1. According to the method in Table 1, it is judged that the viscosity of the printed product of the printing paste is 2-level viscosity.
[0063] 2. Select the anti-adhesive agent composed of paraffin wax, paraffin oil, stearate and silicone oil.
[0064] 3. Mix paraffin, paraffin oil, stearate and silicone oil in a ratio of 2:6:1:1 by weight, and stir mechanically to form a uniform mixture;
[0065] 4. While stirring the printing glue, slowly add the anti-sticking agent prepared according to step 3, whose mass is equivalent to 4.0% of the printing glue mass, and continue stirring until the glue is evenly mixed.
Embodiment 3
[0079] A polyacrylate emulsion printing paste has been prepared, and the anti-sticking agent is added according to the following steps:
[0080] 1. According to the method in Table 1, it is judged that the viscosity of the printed product of the printing glue is a grade 1 viscosity, especially the viscosity is obvious under high temperature and pressure load;
[0081] 2. Select the anti-adhesive agent composed of paraffin wax, paraffin oil, mineral oil, PE wax, and high-grade fatty acid ester.
[0082] 3. Mix paraffin wax, paraffin oil, mineral oil, PE wax, and high-grade fatty acid esters in a weight ratio of 2:4:2:1.5:0.5, and mechanically stir to form a uniform mixture;
[0083] 4. While stirring the printing glue, slowly add the anti-sticking agent prepared according to step 3, whose mass is equivalent to 6.0% of the printing glue mass, and continue stirring until the glue is evenly mixed.
