Foaming printing ink is made up of water-based resin and water as the main body of the water solvent, microspheres by harmonic into foam and other additives.Because of the foam is used in water-based ink connection, so easy to use, no pollution, and ink for silk screen through sexual and reproducibility are good, printing ink layer has good solvent resistance, resistance, abrasion resistance and deformation under heavy load, etc.

     Foaming printing ink used in the emulsion is commonly crosslinking type synthetic resin emulsion, crosslinking acrylic emulsion and with crosslinking reaction oxygen emulsion acrylic emulsion or bad and urethane emulsions.

     Foam foaming printing ink of the microspheres was hot plastic polymer particles, "hollow" shaped, generally using polyvinylidene chloride and propylene eyes, or the methyl acrylic acid and acrylic eyes polymerization.Hollow place contains volatile expansion agent, expansive agent of ethane, propane, butane and other carbon compounds.Microspheres between 5-150 microns in diameter.Ink of microspheres foamed substances content in general for 5-50%, low content of microspheres foaming body, foaming effect is not good, if the content is too high, the ink liquidity is reduced, that there is no uniform ink layer.

     Ink using a variety of dyes, pigments and colorants adjust ink, in order to obtain the required color.

    Ink used in the other auxiliary agent have stable agent, viscosifier, defoaming agent and the oxidation agent to prevent, uv absorber, etc.Will now make foam ink formula is introduced as follows.

Crosslinking type epoxy emulsion was 50%

Ethylene glycol 8%

Microspheres foaming body 25%

Defoaming agent 0.2%

Pigment mixed with water dispersible 1.8%

Crosslinking agent 10%

Water is 5%
