Abstract

The invention provides core-shell matte emulsion as well as a preparation method and application of the core-shell matte emulsion in water matte gloss oil. The emulsion is prepared from the following materials by mass percentage: 38-45% of deionized water, 15-20% of isopropanol, 33-38% of acrylic ester copolymer monomer, 1-3% of dulling material, 2-3% of ammonia water of which the concentration is 25%, 1-2% of compound emulsifier and 0.3-0.5% of initiator ammonium persulfate. The matte emulsion prepared from the materials has the advantages of low glossiness, optimal levelling property and the like, so not only can the dosage of matte powder be reduced by adding the matte emulsion to prepare the matte gloss oil, but also the levelling property and the viscosity stability of the water matte gloss oil can be improved.

Description

Technical field [0001] The present invention is a water -based optical oil technology field. It specially provides a nuclear -shell matte emulsion and its preparation methods and applications in water -matte light oil. [0002] Background technique [0003] Water matte light oil is an environmentally friendly low -gloss coating. Its coating film is soft and has a strong texture, giving a light and comfortable feeling.At present, the water -based matte optical oil is becoming more and more popular and valued in the paper printing industry, and related process formulas are becoming increasingly perfect.For example, a Chinese patent 200410052361.7 revealed a water -based matte light oil and its preparation method. The matte oil coating has good lighting performance and abrasion resistance on the surface of the paper, and can reduce the volatilization of organic solvents, significantly improve production of productionEnvironment; China Patent 200910162098.x also designed a water -bas...
