[0043] A method for preparing an anti-aging coating on the surface of a fertilization tank, comprising the following steps:
[0044] (1) Emulsion preparation:
[0045] Add the emulsifier to deionized water, stir evenly, then add styrene, butyl acrylate, acrylic acid, N-methylol acrylamide, and sodium bicarbonate in sequence, and then stir at 800r / min for 2 hours to obtain a uniform white lotion;
[0046] N-Methylolacrylamide
[0047] Melting point: 74-75°C;
[0048] Density: 1.074;
[0049] Water solubility: <0.1 g / 100 mL at 20.5°C;
[0050] Content (Purity): 99.50%;
[0051] (2) Preparation of grafting agent:
[0052] Add L-aspartic acid and benzyl alcohol to the reaction kettle in sequence, then add concentrated sulfuric acid dropwise, stir and react in a water bath for 40-45min, then let stand for 1 hour, then adjust the pH of the reaction system to neutral, let stand 30min, then carry out vacuum filtration again, carry out recrystallization with distilled water, obt...
