Problems solved by technology

Due to the poor wetting and dispersibility of acrylic resin on pigments, the printing effect is not good (blackheads, water lines), and at the same time, it becomes acrylic resin after curing and deamination. This type of resin is a brittle resin, and the ink film is hard and shrinks greatly. The paper curl is obvious. In addition, looking at the water-based ink printing on tipping paper in my country, there are still the following main problems in the application of tipping paper:
Tipping paper has clear requirements on product odor: there must be no odor that hinders cigarettes. The odor in water-based ink mainly comes from the ammonia substances used in the resin ammoniation process, and the odor is not friendly to the senses.
[0004] (2) Paper deformation is too large
Since the base paper for tipping paper printing has a quantitative range of 31-37g / m2, which is thin paper, water in ink printing will cause the paper to absorb moisture and become soft, resulting in serious deformation of the paper
[0005] (3) The drying speed is too slow
The drying speed of water-based ink is too slow, which affects the printing speed and subsequent processing, and it may also be the phenomenon of fog and paste in the gravure

Abstract

The invention relates to water-based ink for tipping paper. The water-based ink is characterized by comprising the following components in parts by weight: 20-50 parts of water-soluble polyvinyl butyral, 0.1-15 parts of water-soluble modified rosin resin, 0.1-45 parts of a pigment, 0.1-50 parts of a filler, 0.1-1 part of wax powder, 50-95 parts of ethanol, 0.1-95 parts of water and 0.1-1 part of adispersant, wherein the water-soluble modified rosin resin consists of water-soluble maleic acid, pentaerythritol abietate and triethanolamine according to a weight ratio of 1:2:5:2. The water-basedink provided by the invention has the advantages of small odor, low viscosity and good stability.

Description

technical field [0001] The invention relates to the technical field of water-based ink, in particular to a water-based tipping paper ink. Background technique [0002] At present, many printing manufacturers have turned their attention to water-based inks. For this reason, relevant enterprises and units have proposed many technical solutions for "tipping paper printing inks". Such as patent number: 200810233722.6, announcement number: CN101429364 "environmentally friendly antibacterial water-based ink for tipping paper" (water-based acrylic resin); Water-based acrylic resin, water-based acrylic modified rosin resin); etc. However, most of the above-mentioned patents use acrylic or acrylic modified resins to carry out ammoniated water-based. Due to the poor wetting and dispersibility of acrylic resin on pigments, the printing effect is not good (blackheads, water lines), and at the same time, it becomes acrylic resin after curing and deamination. This type of resin is a bri...
