Problems solved by technology

Polyvinyl alcohol (PVA) biodegradable plastics poly-β-hydroxybutyrate (PHB) from a global perspective, PHB and PHBV are recognized as one of the most promising biodegradable plastics, and they are also new products under development. , degradable film lipid groups or carboxyl or hydroxyl groups, some do not do corona treatment during printing, it is more difficult to print and adhere, because it also requires the adaptability of multi-film printing, a single resin system cannot meet the requirements, for this reason, we Propose a water-based ink printed on biodegradable film

Embodiment 1

[0019] Embodiment 1: A water-based ink printed on a biodegradable film, the water-based ink printed on the biodegradable film includes the following raw materials according to the mass percentage;

[0020]

[0021]

[0022] Water-based PU resin is one of caprolactone polyol, isopentyl glycol and adipic acid polyester polyol. It contains more polar groups such as ester groups and amino groups in the molecule, and has strong cohesive strength and adhesion. It has excellent hydrolysis resistance, heat resistance and adhesion. Water-based acrylic resin is one of pure acrylic resin and styrene-acrylic resin. The relative molecular weight of pure acrylic resin and styrene-acrylic resin is relatively large, and it has good gloss and color retention. The water-based dispersant is a polymer block type water-based dispersant, and the polymer block type water-based dispersant easily forms an adsorption layer on the surface of the solid particles, which increases the charge on the su...

Abstract

The invention discloses a water-based ink for printing on a biodegradable film, which is prepared from the following raw materials in percentage by mass: 10-30% of water-based ink, 10-30% of water-based ink, 10-30% of water-based ink and 10-30% of water-based ink, 20-40% of water-based PU resin; 5-20% of water-based acrylic resin; 0-3% of a water-based dispersant; 0-20% of alcohol; 8-15% of a pigment; 0-1% of low-odor amine; 0.2%-1% of a defoaming agent; 0.2%-1% of a flatting agent; 0.2-1% of water-based wax powder; 0.2-1% of a slip agent; the water-based PU resin is one of caprolactone polyol, isoprene glycol and adipic acid polyester polyol, the water-based acrylic resin is one of pure acrylic resin and styrene-acrylic resin, the water-based dispersing agent is a high-molecular block water-based dispersing agent, the alcohol is biological alcohol, and the water-based dispersing agent is a water-based dispersing agent. According to the water-based ink for printing the biodegradable film, popularization and use of biodegradable materials are promoted, energy is saved, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of water-based inks, in particular to a water-based ink printed on a biodegradable film. Background technique [0002] Non-degradable materials refer to polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate (EVA), polyethylene terephthalate ( PET) and other non-biodegradable polymer materials. Conversely, degradable materials cannot contain PE, PP, PS, PVC, EVA, PET, etc. The current types of films, such as PP\PE\PET\PVC, are very stable plastics, and they will not degrade in the natural environment, forming plastics. The main source of white pollution. In order to eliminate white pollution, national legislation promotes biodegradable films. Due to the change of the chemical structure of the film and the adjustment of the printing process, the existing environmental protection ink cannot successfully print the degradable film. There is an urgent need for...
