Detailed Description
The invention provides a metal powder aqueous emulsion, a preparation method thereof and melamine wood grain paper, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a metal powder aqueous emulsion which is used for printing melamine wood-grain paper and comprises the following components in parts by weight:
60-80 parts of water-based acrylic resin emulsion;
10-20 parts of metal powder;
1-3 parts of a dispersing agent;
1-6 parts of a thickening agent;
20-30 parts of water;
the viscosity of the metal powder aqueous emulsion is controlled to be between 15 seconds and 30 seconds (cup No. 3).
Wherein the solid content of the water-based acrylic resin emulsion is 45-50%. The dispersant is maleic anhydride-acrylamide-hydroxyethyl acrylate with the mass fraction of 2000-4000. The dispersing agent can play a role in adsorption to prevent metal powder from precipitating, and prevent the metal powder from agglomerating through the electrostatic action of anions so as to uniformly disperse metal. The maleic anhydride-acrylamide-hydroxyethyl acrylate with the mass fraction of 2000-4000 is adopted, the viscosity of the maleic anhydride-acrylamide-hydroxyethyl acrylate is moderate, flocs cannot be formed due to too high polymerization degree to influence the overall effect of wood grains, and metal powder cannot stably exist in resin due to too low polymerization degree. Meanwhile, the particle size of the metal powder is required in the invention, and the excessive particle size ensures that the metal powder particles are heavier than resin and are easy to precipitate downwards, so that the particle size of the metal powder is limited to be between 10 and 40 mu m, the excessive mass of the metal powder particles is prevented, the metal powder can be uniformly suspended in a resin system better, and the precipitation cannot occur in a long time. The thickening agent adopts polyethylene glycol-2000, the viscosity of the metal powder aqueous emulsion is controlled between 15 seconds and 30 seconds (No. 3 cup), and the effect of hindering the precipitation of metal particles is achieved.
The invention also provides a preparation method of the metal powder water-based emulsion for the melamine wood grain paper, which comprises the following steps:
adding water into the water-based acrylic resin emulsion under the stirring state, and uniformly stirring;
slowly adding metal powder and a dispersing agent, and stirring and mixing uniformly;
adding a thickening agent, and stirring and mixing uniformly to obtain the metal powder aqueous emulsion.
Preferably, the preparation method further comprises the following steps:
feeding the aqueous emulsion of the metal powder into a bead mill for at least 2 times of grinding. Thus, the metal powder can be more thoroughly and uniformly dispersed in the aqueous emulsion of the metal powder.
Through observation, the metal powder aqueous emulsion can not generate obvious color difference caused by metal powder precipitation within 10 hours, and can ensure that the precipitation can not be generated in the whole printing process. Meanwhile, the mass production experiment verifies that the metal powder water-based emulsion does not have color difference caused by metal powder precipitation in the whole printing process, the wood grain patterns and the colors of the melamine wood grain paper at the front section and the rear section can be kept consistent, the product percent of pass is high, and the return quantity is obviously reduced. Even if the metal powder aqueous emulsion is stored for 1 month, the bottom of the metal powder aqueous emulsion has no hard precipitate, and the metal powder aqueous emulsion can be uniformly dispersed by stirring.
