Abstract

The invention belongs to the technical field of printing ink and particularly relates to a UV offset print freezing-point printing ink and a preparation method thereof. The UV offset print freezing-point printing ink is prepared from the following raw materials in parts by weight: 30-50 parts of macromolecular resin junction material, 30-50 parts of a reactive diluent, 5-10 parts of a photoinitiator, 8-15 parts of a filler and 0.1-2 parts of an accessory ingredient. The UV offset print freezing-point printing ink is applied to product package printing, and has the advantages of rapid curing speed, short curing time, long storage time, good stability, strong adhesive force, rub resistance, water resistance, ageing resistance, high glossiness, bright color, distinctive line and the like.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a UV offset printing freezing point ink and a preparation method thereof. Background technique [0002] Freezing point ink, also known as snowflake ink, in the industry, the pattern of "snowflake" is larger, generally larger than 2mm, and the pattern of "freezing point" is smaller, generally less than 2mm. Freezing point ink is a kind of UV ink that can produce fine and uniform texture on the surface of the ink after twice curing, which can protect and decorate the surface of the product, so it is widely used in the packaging and printing industry, especially in the domestic cigarette pack printing industry . [0003] Resin is one of the important components of ink. It is divided into two types: UV resin and ordinary resin. The former needs to be cured by UV light of a specific wavelength, and the latter can be cured under specific temperature (or heat) conditions. In t...
