Anti-leakage ball-point pen ink and preparation method thereof

[0027] Alcohol Solvent Black 46 30%

[0028] Ethylene glycol phenyl ether 15%

[0029] Benzyl Alcohol 25%

[0030] Epoxy 13%

[0031] Ketone resin 7%

[0032] BYK410 3.5%

[0033] Triethanolamine 5.5%

[0034] Its preparation process is as follows:

[0035] (1), alcohol-soluble solvent black 46 and ethylene glycol benzoate, benzyl alcohol are dropped in the reaction kettle by proportioning, prepare alcoholic solvent;

[0036] (2) Add the two resins in proportion to heat up and stir, and the temperature is controlled at 90-93°C;

[0037] (3) After 8 hours of heat preservation, add BYK410 and triethanolamine in proportion to fully stir, and finally perform centrifugation and filtration to obtain this product.

[0038] Take some of this product and pour it into the experimental refill, hang it vertically in a drying oven with a temperature of 60°C. Compared with other types of products, the nib is clean and there is no ink leakage, and its leakage resistance is better.
