Problems solved by technology

Waterborne polyurethane has many advantages, but at the same time there is a serious disadvantage: since water is used as the dispersion medium, hydrophilic groups such as -COOH and -OH will inevitably be introduced into the molecular structure of polyurethane, making its water resistance relatively poor. Traditional solvent-based polyurethane is very different
In order to reduce ink static electricity, two types of conductive metal powder and carbon-based conductive materials will be added to the ink. The conductive metal powder has low resistance and good conductive effect, but it is expensive and easy to be oxidized, causing the resistance to gradually increase. Poor dispersion in film resins

Embodiment 1

[0024] Preparation of antistatic agent: take raw materials according to the following formula quantity: quaternary ammonium salt cationic surfactant 48%, aminoethanol 16%, acetic acid 16%, isopropanol 16%, water 4%, and above-mentioned raw material is stirred in the mixer The quaternary ammonium salt cationic antistatic agent can be prepared uniformly.

[0025] Preparation of silver-plated graphite powder: Before silver-plating, the graphite powder needs to be pretreated by degreasing, roughening, sensitizing, washing, and drying. Take anhydrous glucose, add distilled water, absolute ethanol, polyethylene glycol (400), stir and dissolve to prepare about 0.75% glucose reducing solution. First take 30% silver ammonia solution as the activation solution according to the amount, treat the graphite powder after sensitization, stir and activate for 20 minutes, add the silver ammonia solution into the plating solution, then slowly add the glucose reduction solution under stirring, an...

The novel environmentally-friendly antistatic water-based plastic gravure printingink comprises the following components in weight ratios: 30-35 parts of a water-based multi-component compound modified polyurethane emulsion, 10-15 parts of water-based chloroacetate resin, 8-13 parts of silver plating graphite powder body, 0.2-0.5 part of a quaternary ammonium salt cationic antistatic agent, 0.5-1 part of an oxidized polymer adhesion enhancer, 0.5-1 part of water-based polyethylene wax micro-powder, 0.3-0.5 part of water-soluble nano-silica, 0.01-0.03 part of a de-foaming agent, 1-3 parts of ethanol, 15-30 parts of water and 10-15 parts of pigments. The novel environmentally-friendly antistatic water-based plastic gravure printing ink is suitable for aqueous system, strong in antistatic force, low in cost, relatively good in water resistance, relatively high in resistance to stickiness, improved in storage stability, green, environmentally-protective, safe and strong in comprehensive performance.

Description

technical field [0001] The invention relates to a water-based plastic gravure printing ink, in particular to a novel environment-friendly antistatic water-based plastic gravure printing ink which uses plastic as a base material and is applied in a gravure printing method. Background technique [0002] At present, gravure printing inks are widely used in the plastic packaging industry. For the flexible packaging printing industry that mostly involves food and daily necessities packaging, water-based inks are mostly used. Water-based ink is an ink with water as a solvent. The advantages of water as a solvent are: non-toxic, no peculiar smell, non-flammable, and greatly reduce VOC emissions, reducing environmental pollution. Water-based polyurethane ink is a kind of water-based ink, which is mainly used in the field of gravure printing. It not only has the characteristics of safety and environmental protection of water-based ink, but also has excellent wear resistance and chemi...
