Embodiment 1
[0026] A kind of processing technology based on the electrophoretic paint of acrylic resin, comprises the following steps:
[0027] S1, in parts by mass, put 35 parts of acrylic resin, 15 parts of amino resin, 4 parts of trimethylolpropane and 5 parts of blocked isocyanate into a container for heating, and keep it at 80°C for 5 hours;
[0028] S2, quickly cool down S1 to minus 15°C, keep it for 0.5h, and then naturally warm up to room temperature to obtain mixture 1;
[0029] S3, mixing 8 parts of ethyl cellulose, 3 parts of dibutyl phthalate and 4 parts of polycaprolactone diol in parts by mass and grinding for 1 hour;
[0030] S4, adding 1 part of lead oxide to S3, and bathing in water at 65°C for 2 hours to obtain mixture 2;
[0031] S5, mixing and stirring the mixture 1 and the mixture 2 to obtain a paint.
Embodiment 2
[0033] A kind of processing technology based on the electrophoretic paint of acrylic resin, comprises the following steps:
[0034] S1, in parts by mass, put 50 parts of acrylic resin, 10 parts of amino resin, 6 parts of trimethylolpropane and 3 parts of blocked isocyanate into a container for heating, and keep it at 100°C for 3 hours;
[0035] S2, the temperature of S1 is rapidly cooled to minus 10°C, kept for 1 hour, and then naturally warmed to room temperature to obtain a mixture 1;
[0036] S3, mixing 5 parts of ethyl cellulose, 5 parts of dibutyl phthalate, 4 parts of phenolic resin and 2 parts of polycaprolactone diol in parts by mass and grinding for 1.5 hours;
[0037] S4, adding 2 parts of lead oxide to S3, and bathing in water at 50°C for 2.5 hours to obtain mixture 2;
[0038] S5, mixing and stirring the mixture 1 and the mixture 2 to obtain a paint.
Embodiment 3
[0040] A kind of processing technology based on the electrophoretic paint of acrylic resin, comprises the following steps:
[0041] S1, in parts by mass, put 40 parts of acrylic resin, 12 parts of amino resin, 5 parts of trimethylolpropane and 4 parts of blocked isocyanate into a container for heating, and keep it at 90°C for 4 hours;
[0042] S2, the temperature of S1 is rapidly cooled to minus 12°C, kept for 1.2h, and then naturally warmed to room temperature to obtain a mixture 1;
[0043] S3, mixing 6 parts of ethyl cellulose, 4 parts of dibutyl phthalate, 8 parts of phenolic resin, 2 parts of petroleum resin and 3 parts of polycaprolactone glycol in parts by mass and grinding for 1.2 hours;
[0044] S4, adding 1.5 parts of lead oxide to S3, and bathing in water at 55°C for 2.2 hours to obtain mixture 2;
[0045] S5, mixing and stirring the mixture 1 and the mixture 2 to obtain a paint.
