Problems solved by technology

However, the above two methods have great disadvantages: the former has great difficulty in material selection, and if the material is not well selected, the prepared emulsion will be layered quickly, and printed products are prone to streaks; the latter is due to the addition of Matting powder, the storage time is short, it can not meet the requirements of long-distance transportation and storage, and it is easy to produce matting powder dur

Example Embodiment

[0036] Example 1:

[0037] 1458 grams of deionized water and 6 grams of water-soluble initiator amine persulfate were added to a four-necked flask equipped with a thermometer, a reflux condenser, a dripping device and stirring, and the temperature was raised to 83°C. Add 500 grams of deionized water, 6 grams of reactive emulsifier sodium acrylamidoisopropyl sulfonate, 150 grams of acrylamide, 170 grams of N-methylol acrylamide, 40 grams of methacrylic acid, and methacrylic acid into the high-level tank 50 grams of methyl ester, 50 grams of styrene, and 20 grams of molecular weight regulator 3-mercaptopropanol were pre-emulsified. The pre-emulsified mixed monomer was added dropwise into the flask by the "starvation method" within the temperature range of 80°C to 85°C, and the dropwise addition time was 90 minutes. After the dropwise addition, 38 grams of ammonia water was added to adjust the pH value of the emulsion to 8.5, and the temperature was kept for 30 minutes to prepar...

[0039] Example 2:

[0040] 1146 grams of deionized water and 8 grams of water-soluble initiator amine persulfate were added to a four-necked flask equipped with a thermometer, a reflux condenser, a dropping device and stirring, and the temperature was raised to 83°C. Add 500 grams of deionized water, 10 grams of allyl-containing special alcohol ether sulfate, 248 grams of acrylamide, and 72 grams of N-methylol acrylamide in the high-level tank (the effective content accounts for 7.5%), 40 grams of methacrylic acid, 50 grams of methyl methacrylate, 50 grams of styrene, and 20 grams of molecular weight regulator tert-dodecanethiol for pre-emulsification. The pre-emulsified mixed monomer was added dropwise into the flask by the "starvation method" within the temperature range of 80°C to 85°C, and the dropwise addition time was 90 minutes. After the dropwise addition, 50 g of monoethanolamine was added to adjust the pH value of the emulsion to 8.5, and the temperature was kept fo...

[0042] Example 3:

[0043] 1171 grams of deionized water and 8 grams of water-soluble initiator amine persulfate were added to a four-necked flask equipped with a thermometer, a reflux condenser, a dripping device and stirring, and the temperature was raised to 83°C. Add 500 grams of deionized water, 10 grams of alcohol ether thiosuccinate sodium salt of reactive emulsifier containing double bonds, 176 grams of acrylamide, and 144 grams of N-methylol acrylamide (effective content accounts for the monomers) 15% of the total amount), 40 grams of methacrylic acid, 50 grams of methyl methacrylate, 50 grams of styrene, and 20 grams of n-dodecyl mercaptan acetate as a molecular weight regulator for pre-emulsification. The pre-emulsified mixed monomer was added dropwise into the flask by the "starvation method" within the temperature range of 80°C to 85°C, and the dropwise addition time was 90 minutes. After the dropwise addition, 25 grams of diethanolamine was added to adjust the p...

Abstract

The invention relates to the technical field of water-base varnish and discloses matte degree controllable core-shell emulsion as well as a preparation method and application thereof to water-base matte varnish. The matte degree controllable core-shell emulsion comprises a vinyl monomer, an initiator, a molecular weight modifier, a reactive emulsifier, a pH modifier and deionized water. The matte emulsion with different matte degrees can be obtained by changing the amount of N-hydroxymethyl acrylamide in the shell vinyl monomer, has long storage time and good weather resistance and water resistance and dispenses with matting agents. The water-base matte varnish prepared from the matte degree controllable core-shell emulsion has the advantages of long storage time, good stability, good printing adaptability and the like.

Description

technical field [0001] The invention relates to the technical field of water-based varnish, in particular to a core-shell emulsion with controllable matt degree, a preparation method thereof and an application in water-based matte varnish. Background technique [0002] With the rapid and steady development of the market economy and the commodity economy, people pay more and more attention to the printing and decoration of food packaging, books, magazine covers, calendars, pictures, medicine boxes, cigarette packs, etc., not only require the printing of exquisite color pictures, And hope to have a magnificent surface gloss. This glossiness is the special effect produced by coating varnish on the printed matter. [0003] The coating and glazing market is a diversified market. Food printing plants, book printing plants, commercial printing plants, trademark printing plants and folding carton printing plants all have varying degrees of glazing requirements for various packaging...
