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.

Abstract

The invention relates to the technical field of paint processing, and discloses electrophoretic paint based on acrylic acid resin as well as a processing process thereof. The electrophoretic paint based on the acrylic acid resin comprises the following components: 35 to 50 parts of acrylic acid resin, 10 to 15 parts of amino resin, 5 to 8 parts of ethyl cellulose, 3 to 5 parts of dibutyl phthalate, 2 to 4 parts of polycaprolactone diol, 1 to 2 parts of lead oxide, 4 to 6 parts of trimethylolpropane and 3 to 5 parts of a crosslinking agent. The acid and alkali resistance of workpieces can be improved.

Description

technical field [0001] The invention relates to the technical field of electrophoretic paint, in particular to electrophoretic paint based on acrylic resin and its processing technology. Background technique [0002] Electrophoresis is becoming more and more popular as the pitfalls of conventional spraying continue to surface. Moreover, electrophoretic coatings have also begun to be continuously updated, from anodic electrophoretic coatings to cathodic electrophoretic coatings, from single-component electrophoretic coatings to two-component electrophoretic coatings, the development of electrophoretic coatings has also promoted the development of electrophoretic coatings, making more products without Instead of spraying techniques, electrophoresis is used. [0003] Cathodic electrophoretic coatings can be mainly divided into: epoxy electrophoretic coatings, acrylic electrophoretic coatings and polyurethane electrophoretic coatings. Acrylic electrophoretic coating has super ...
