Problems solved by technology

[0003] However, in the existing snowflake inks, in order to maintain the fineness of the snowflake pattern, inorganic particles are often not used, so as to avoid the inorganic particles becoming solid cores to attract other newly formed particles during the photocuring process, resulting in rough snowflake patterns , even become foggy

Abstract

The present invention provides a preparation method of toughening and abrasion-resistant snowflake ink, and the preparation method comprises the following steps: 1) 10-20 parts of amino-acrylic acid resin, 15-40 parts of epoxy acrylic resin, 8-30 parts of poly formaldehyde resin, 15-40 parts of tripropylene glycol diacrylate, 5-20 parts of trimethylolpropane triacrylate and 0.1-0.3 part of a polymerization inhibitor are added into a blender and stirred until no particle exists in the mixture; 2) 8-20 parts of photosensitive nano silica and 1-2 parts of a leveling agent are added, and the reaction mixture is stirred evenly; 2-1) the stirring is stopped, the mixture is statically placed for 8 to 16 hours in dark at room temperature, and the mixture is stirred for 0.5 to 1 hour under 4000-4500rpm; and 3) a photoinitiator and a photosensitive accelerant are added, and stirred evenly to obtain the toughening and abrasion-resistant snowflake ink, the photosensitive nano silica is silica modified by Vinyl trimethoxy silane, the particle diameter is 45 to 80nm, and the modifying bonding ratio is 85% to 95%. The invention also provides the toughening and abrasion-resistant snowflake ink which has the advantages of good surface gloss and permeability, high hardness, good toughness and strong abrasion resistance.

Description

technical field [0001] The invention belongs to the technical field of snowflake ink, in particular to a toughened and wear-resistant snowflake ink and a preparation method thereof. Background technique [0002] UV curing silk screen snowflake printing is a special process for surface treatment of printed matter, which can produce transparent and three-dimensional patterns on the color printing pattern of printed matter, so that the printed pattern can display novel and high-end decorative effects. UV curing screen printing snowflake ink first prints the ink on the pattern surface of the printed matter through a printing machine, and then detonates and solidifies to present a crystal clear texture like winter snowflakes, commonly known as "snowflakes" (larger patterns, generally larger than 2mm) Or "freezing point" (the pattern is small, generally the pattern is less than 2mm), which is a special process ink of crystallization and fission type. [0003] However, in the exis...
