Embodiment 1

[0015] A preparation method of antistatic powder coating, comprising the following steps:

[0016] (1) Get 2 parts by weight of triglycidyl isocyanurate and 16 parts by weight of acetylene carbon black and mix them, add them to dimethyl carbonate with 10 times the weight of the mixture, ultrasonically for 1 hour, and raise the temperature to 70°C. Add 0.4 parts by weight of oleic acid diethanolamide, heat and stir for 20 minutes to obtain an amide dispersion;

[0017] (2) 10 parts by weight of stearic acid is heated and softened, mixed with 8 parts by weight of triethanolamine, sent into the reaction kettle, added p-toluenesulfonic acid of 1% by weight of the mixture, and fed with nitrogen to adjust the reaction The temperature of the kettle was 165°C, and the reaction was stirred for 5 hours to obtain the ester amine;

[0018] (3) Take the above-mentioned ester amine, add it to the above-mentioned amide dispersion, stir evenly, send it into the reaction kettle, pass in nitro...

Abstract

The invention discloses a preparation method of an antistatic powder coating material, comprising the following steps: firstly dispersing acetylene black by using a dimethyl carbonate solution of oleic acid diethanolamide, then esterifying stearic acid and triethanolamine under the action of a catalyst. dispersing obtained ester amine in an amide solution, and reacting ester amine with dimethyl carbonate to obtain an antistatic solution containing quaternary ammonium salt. The preparation method has the advantages of not only effectively improving the antistatic effect, but also improving thesurface activity of the acetylene black, thus enhancing the dispersion compatibility of the acetylene black in a polypropylene matrix, improving the uniform stability of the finished coating material,improving the antibacterial and anti-yellowing properties and the like of the finished coating material by the reaction, and enhancing the finished product quality.

Description

technical field [0001] The invention belongs to the field of antistatic powder coatings, and in particular relates to a preparation method of antistatic powder coatings. Background technique [0002] Antistatic is the name of static conductive coatings. There are antistatic coatings and antistatic coatings. According to a series of standards formulated by the country, conductive coatings are used. From the design of industrial buildings and equipment, conductive coatings are used. From the functional analysis of coatings, the performance of coatings In a short period of 10-2 seconds, discharge the static voltage accumulation to avoid accidents that cause fire or damage electronic components due to discharge. The generation and accumulation of static electricity is an objective existence in nature and there is no resistance to it. It is used for fabrics. Antistatic agent products that have not tested the theory of conduction and leakage can prevent the accumulation of static ...
