Problems solved by technology

[0002] In offset printing, ordinary offset UV varnish mainly protects the product, and it is difficult to form a mirror effect on the surface of the product. The present invention aims to provide a mirror effect that can be realized on the surface of ordinary printing paper to reflect external light. To realize the mirror function, so that consumers can use it as a simple mirror, so that the product has a strong counter effect and visual effect, and has certain practicability, and meets the environmental protection requirements of cigarette packaging

Embodiment 1

[0010] Prepare the following raw materials first: 210g of standard bisphenol A epoxy acrylate, 630g of dipropylene glycol diacrylate, 50g of polyethylene glycol o-benzoylbenzoate, and 110g of reactive tertiary amine.

[0011] Preparation method: first add one-fifth of dipropylene glycol diacrylate (monomer) and one-fifth of standard bisphenol A epoxy acrylate (UV resin) into the mixing tank, and start the high-speed disperser (equipment model F250 , purchased by Jiangsu Hongliu Chemical), the speed is 400 rpm, and after stirring and dissolving, add polyethylene glycol o-benzoylbenzoate (initiator), and the stirring speed is increased to 800-1000 rpm, so that the temperature can be raised to dissolve the initiator. Stir to dissolve until transparent and free of particles, then add the remaining dipropylene glycol diacrylate (monomer) and the remaining standard bisphenol A epoxy acrylate (UV resin), stir evenly, after cooling to room temperature, add reactive tertiary amine (co-...

Embodiment 2

[0014] 190g of standard bisphenol A epoxy acrylate, 640g of dipropylene glycol diacrylate, 70g of polyethylene glycol o-benzoylbenzoate, and 100g of reactive tertiary amine.

[0015] Raw materials are prepared according to the above proportions during mass production, and the preparation process refers to Example 1.

Embodiment 3

[0017] 200g of standard bisphenol A epoxy acrylate, 650g of dipropylene glycol diacrylate, 60g of polyethylene glycol o-benzoylbenzoate, and 90g of reactive tertiary amine.

[0018] Raw materials are prepared according to the above proportions during mass production, and the preparation process refers to Example 1.

Abstract

The invention relates to an offset UV varnish printing ink with mirror surface effect and a preparation method of the offset UV varnish printing ink. The offset UV varnish printing ink with mirror surface effect is characterized by comprising the following compositions in percentage by weight: 19%-23% of standard bisphenol A epoxy acrylate, 61%-65% of dipropylene glycol diacrylate, 3%-7% of p-benzoyl polyethylene glycol benzoate, and 9%-13% of reactive tertiary amine. According to the invention, the offset UV varnish printing ink with mirror surface effect has good levelness and transparency without addition of auxiliaries such as a leveling agent and a defoaming agent, the offset and polished product has a mirror-like effect, and the smooth, level and transparent effects of a mirror can be simulated on a paper package by means of printing. No reaction auxiliaries are added in the printing ink, so that the curing resistance can be reduced, and the influence on the transparency and compatibility of the printing ink can be reduced. The printing ink is less in side reaction in curing reaction, low in migration rate and volatility, thus having high environment-friendly property; and the Vocs smell can completely achieve the national standard requirement.
