Abstract

The invention discloses printing paste used for gold powder printing of stone wall paper and a preparation method. The printing paste is prepared by carrying out the following steps: emulsifying 2.0-2.2 parts by mass of 1,4-butanediol dimethacrylate, 1.0-1.1 parts by mass of itaconic acid, 130-140 parts by mass of ethyl acrylate, 31-32 parts by mass of butyl acrylate, 6.4-6.6 parts by mass of hydroxyethyl methylacrylate, 27-28 parts by mass of methyl methacrylate, 4.0-4.2 parts by mass of 2-(methacryloyloxy)ethyl acetoacetate, 32-33 parts by mass of styrene, 2-2.3 parts by mass of fatty alcohol-polyoxyethylene ether 23E9 and 230-250 parts by mass of deionized water, and initiating polymerization; compounding 20-25 parts by mass of a mixed solution of sorbitol and benzotriazole, 20-22 parts by mass of an associative leveling rheological agent and 10-15 parts by mass of an acrylic dispersant, and mixing. The printing paste in high in transparency, glossiness and fastness, and is resistant to air oxidation.

Description

technical field [0001] The invention relates to a printing paste for stone wallpaper gold powder printing, that is, the printing paste used for printing gold patterns on stone wallpaper. Background technique [0002] Stone wallpaper is made of calcium carbonate as the main raw material, polymer materials and various inorganic substances as auxiliary materials. [0003] The prior art does not have special printing paste for stone wallpaper, and adhesives are used instead of printing paste, such as the adhesive IT of BASF, adding thickener, water, and printing paste to mix to make stone wallpaper printing paste. The gloss, elasticity, and hand feeling of the printed pattern are not satisfactory, and the unevenness is not strong. Especially in gold powder printing, the above shortcomings are more obvious, and the air oxidation resistance is not good, and it is easy to lose the gorgeous luster of gold powder. [0004] As for the printing paste for gold powder printing of stone...
