Embodiment 1

[0041] Dissolve 5 g of sodium lauryl sulfate (emulsifier) ​​and 3 mL of OP-10 in 100 mL of water, and then transfer them to a three-necked flask. After dissolving 0.5 g of ammonium persulfate with 50 mL of water, it was added to the above-mentioned three-necked flask, stirred with a mechanical stirrer, and heated. Mix three kinds of monomers, including 100mL of methyl methacrylate, 100mL of butyl acrylate and 10mL of methacrylic acid. Use), join in the above-mentioned three-necked flask, the reaction temperature is constant, and the reaction time is 20min. The remaining mixed monomers were added dropwise to the reaction solution in the three-necked flask with a dropping funnel, and then the initiator solution (aqueous solution of ammonium persulfate) was added dropwise. The reaction temperature when the initiator solution was added dropwise was 70°C. After the dropwise addition was completed, the reaction was continued for 30 min.

Embodiment 2

[0043] Dissolve 8g of sodium lauryl sulfate (emulsifier) ​​and 2mL of OP-10 in 120mL of water, and then transfer them to a three-necked flask. After dissolving 0.8 g of dibenzoyl peroxide with 50 mL of water, it was added to the above-mentioned three-necked flask, stirred with a mechanical stirrer, and heated. Mix three kinds of monomers, including 150mL of nonyl acrylate, 90mL of butyl methacrylate and 10mL of acrylic acid. When the temperature of the solution in the three-necked flask rises to 80°C, take 20mL of mixed monomers (the remaining mixed monomers are for use) , added in the above-mentioned three-necked flask, the reaction temperature was constant, and the reaction time was 20min. The remaining mixed monomers were added dropwise to the reaction solution in the three-necked flask with a dropping funnel, and then the initiator solution (aqueous solution of dibenzoyl peroxide) was added dropwise. The reaction temperature when the initiator solution was added dropwise w...

Embodiment 3

[0045] Dissolve 10 g of sodium lauryl sulfate (emulsifier) ​​and 5 mL of OP-10 in 150 mL of water, and then transfer them to a three-necked flask. After dissolving 1.0 g of azobisisobutyronitrile with 50 mL of water, it was added to the above-mentioned three-necked flask, stirred with a mechanical stirrer, and heated. Mix three kinds of monomers, including 120 mL of methyl methacrylate, 100 mL of butyl methacrylate and 6 mL of methacrylic acid. When the temperature of the solution in the three-necked flask rises to 100° C., take 40 mL of the mixed monomers (the remaining Body stand-by), join in the above-mentioned three-necked flask, the reaction temperature is constant, and the reaction time is 20min. The remaining mixed monomers were added dropwise to the reaction solution in the three-necked flask with a dropping funnel, and then the initiator solution (azobisisobutyronitrile aqueous solution) was added dropwise. The reaction temperature when the initiator solution was added ...

Abstract

The invention discloses a method for preparing multi-color long afterglow water borne luminescent coatings. The coating is prepared by taking a high molecular polymer formed by mutual polyreaction of three monomers through initiating agents as acrylic emulsion, taking the synthetic acrylic emulsion as a base resin of the coating and adding luminescent powder, auxiliary agents and fillers; the prepared multi-color long afterglow water borne luminescent coatings have good luminescent property, wear-resisting property, adhesion property and the like. The coatings feature simple preparation process and convenient construction, and compared with the traditional oil soluble luminescent coatings, the coatings discharge no noxious solvents and enjoy environment-friendly production process.

Description

technical field [0001] The invention belongs to the field of light industry and chemical materials; the invention specifically relates to a method for preparing a long afterglow luminescent paint with good comprehensive performance by using acrylic acid emulsion as a base material. Background technique [0002] Long afterglow luminescence is a photoluminescence phenomenon, which refers to the phenomenon that a substance can continue to emit light after the excitation light stops being irradiated. Different luminescent materials have different luminous attenuation properties. Some materials have a very short luminous duration, while others have a long duration. Rare earth long afterglow luminescent material is a new type of environmental protection and energy-saving material. It can store part of the energy after absorbing the energy of sunlight or light, and then slowly release the stored energy in the form of visible light. Can emit visible light for a long time. Utilizin...
