Embodiment 1

[0051] Embodiment 1: a kind of varnish, including the components shown in Table 1 in parts by weight.

[0052] The above-mentioned high-strength impermeable concrete is prepared through the following steps:

[0053] S1, take the emulsifier and water in corresponding parts by weight, heat in a water bath to 80° C. to dissolve, and stir at high speed to obtain an emulsified solution. Take corresponding parts by weight of methyl methacrylate, butyl acrylate, acrylic acid, acrylonitrile and hydroxyethyl acrylate, mix them uniformly, add them into the emulsified solution, and mix them uniformly to obtain a seed emulsion.

[0054] S2, taking corresponding parts by weight of polyvinyl alcohol powder and initiator and mixing to obtain an additive liquid. Take 20% of the seed emulsion, add 1 / 3 of the additive solution, mix evenly to obtain a reaction solution, and control the reaction temperature at 80°C. After the reaction solution turns blue, add the remaining seed emulsion and the...

Embodiment 2-7

[0057]Embodiment 2-7: a kind of glazing oil, the only difference from embodiment 1 is that the parts by weight of some components are different; the components and parts by weight are shown in Table 1.

[0058] Components and their corresponding parts by weight in table 1. embodiment 1-7

[0059]

Embodiment 8-9

[0060] Embodiment 8-9: A kind of glazing oil, the only difference from Embodiment 1 is that polyethylene glycol monomethyl ether methacrylate with relative molecular weights of 1000 and 1200 are selected.

Abstract

The invention discloses a glazing oil and a preparation method thereof, and relates to the technical field of printing; the glazing oil comprises the following components in parts by weight: comonomer: 1105-1578 parts; water: 1108-1568 parts; emulsifier: 80‑138 parts; sodium hydroxide: 104‑151 parts; initiator: 94‑121 parts. Among them, comonomers include methyl methacrylate, butyl acrylate, acrylic acid, acrylonitrile, and hydroxyethyl acrylate; emulsifiers include polyethylene glycol monomethyl ether methacrylate and / or p-styrenesulfonic acid sodium. The glazing oil is prepared through the following steps: S1, take the copolymerization unit, sodium hydroxide, emulsifier and water of the corresponding parts by weight, heat and dissolve, and mix uniformly to obtain the seed emulsion; S2, take the initiator of the corresponding parts by weight Add it into the seed emulsion and mix evenly to obtain an emulsion polymer. The invention has the advantage of improving the leveling property of the glazing oil.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a varnish and a preparation method thereof. Background technique [0002] Glazing oil refers to a liquid that is coated on the surface of printed matter to increase gloss, abrasion resistance and water resistance. Varnishes include water-based varnishes, oil-based varnishes, UV varnishes, and alcohol-soluble varnishes. At present, water-based varnish is the most widely used in China, because it has very good environmental protection performance. [0003] The Chinese patent with the authorized announcement number CN104845500B and the authorized announcement date on March 1, 2017 discloses a printing varnish, which is composed of the following raw materials: water-soluble acrylic epoxy resin, mussel mucin, Calcium acetate, acrylates, solvents, and functional additives are specifically prepared through the following steps: add acrylates to the water-soluble acrylic epoxy resin in...
