[0034]Add 20kg of cetyltrimethylammonium chloride and 300kg of deionized water into the reactor for mixing, and stir evenly until the cationic emulsifier is completely dissolved in the deionized water, then raise the temperature to 75°C to obtain an emulsifier solution. Subsequently, 410kg of acrylic acid and 270kg of deionized water were put into an emulsification tank for mixing and stirred for 25 minutes until the acrylic acid and deionized water were evenly mixed to obtain a pre-emulsion. Then add 90kg of pre-emulsion to the reaction kettle, that is, the emulsifier solution, then add 3.3kg of sodium ferric edetate and stir evenly, then raise the temperature of the reaction system to 80°C, and then continue to stir for 5 minutes to make the reaction system become The transparent system was then kept at a temperature of 80° C. for 20 minutes to make blue light appear in the reaction system.

Abstract

The invention discloses metal chelating type cationic emulsion for waterborne woodenware close primer and a preparation method thereof. The metal chelating type cationic emulsion is prepared from a cationic emulsifier, acrylic acid, an initiator, a metal ion chelating agent, a pH (Potential of Hydrogen) regulator and de-ionized water. According to the metal chelating type cationic emulsion disclosed by the invention, the crosslinking density and the film forming rigidity of the emulsion are improved in the presence of the metal ion chelating agent, so that a paint film formed by the prepared close primer has high density, good rigidity and excellent sealing performance; especially, the metal chelating type cationic emulsion has excellent sealing performance on tannic acid.

Description

technical field [0001] The invention relates to the technical field of emulsions, in particular to a metal chelating cationic emulsion for a water-based wood sealing primer and a preparation method thereof. Background technique [0002] After more than ten years of promotion in my country, water-based wood lacquers have made great progress. In recent years, with the improvement of people's awareness of environmental protection, water-based wood paint has become more and more optimistic about the coating industry and consumers because of its environmental protection, and has placed good expectations for development. However, in the process of construction and promotion of water-based wood coatings, there is a problem that is difficult to solve, that is, bleeding phenomenon: when solid-color water-based wood coatings are painted, especially light-colored or white coatings, the surface of the paint film is easy to change color, which directly affects the decoration of the coati...
