Embodiment

[0027] Embodiment: the preparation of ultraviolet curing hydrophilic coating:

[0028] Mix the hydrophilic unsaturated polyester amide urea with the acrylate monomer and initiator 184 in a weight ratio of 20:10:1, then add 3% of total surfactant, 0.05% of defoamer and The total amount of 100% water is put into a container with a stirrer, placed in a water bath, protected by nitrogen, and stirred at 25°C for 30 minutes to prepare a brown-black liquid UV-curable hydrophilic coating with a certain viscosity.

Abstract

The invention relates to an ultraviolet light-cured hydrophilic coating and a preparation method thereof. The method comprises the steps of mixing hydrophilic unsaturated polyester-urea amide, acrylic ester crosslinking monomers and an initiator according to a certain ratio; adding a proper amount of auxiliary agents and a diluent; stirring at a temperature of 25 DEG C, and thus the brownish black ultraviolet light-cured hydrophilic coating having a certain viscosity is obtained. The ultraviolet light-cured hydrophilic coating employs ultraviolet light to cure for film formation, has the characteristics of high efficiency, energy conservation and good hydrophilicity. The ultraviolet light-cured hydrophilic coating is expected to be used for hydrophilic coating of hydrophilic aluminium foil, plastic, glass, and the like, and provides excellent hydrophilic performance for the above.

Description

technical field [0001] The invention relates to a chemically synthesized hydrophilic polymer coating and a method thereof. Using unsaturated diacid (anhydride) (maleic anhydride or fumaric acid) and C 2 ~C 4 Fatty dihydric alcohol, diethylene glycol, and urea are copolymerized to obtain a hydrophilic unsaturated polyester amide urea matrix resin. This kind of resin is mixed with acrylate cross-linking monomer, and one or more of 1173, 184, TPO is used as an initiator, and additives and diluents are added to prepare a UV-curable hydrophilic coating. This type of hydrophilic coating can be used as hydrophilic coating for substrates such as glass, plastic, copper sheet (foil), aluminum sheet (foil) and the like. When used in glass, it can improve the anti-fog, anti-fouling, and light transmittance of glass; when used in plastic, it can improve its biocompatibility; when used in aluminum foil, it can improve the heat exchange effect of aluminum foil used in air conditioners, wh...
