Waterborne ink and preparation method thereof as well as application of waterborne ink in PP (Polypropylene) decorative film

Abstract

The invention discloses a waterborne ink and a preparation method thereof, application of the waterborne ink in a PP (Polypropylene) decorative film and a preparation method of the PP decorative film. The preparation method of the waterborne ink comprises the following process steps: a, preparing mill base; b, grinding; and c, blending ink. The PP decorative film sequentially comprises a PP substrate layer, a waterborne ink printing layer and a varnish coating layer from bottom to top. The preparation method of the PP decorative film comprises the following process steps: 1) carrying out polarity treatment on the surface of the PP film; 2) preparing the waterborne ink; 3) printing the waterborne ink; 4) glazing and coating; and 5) embossing. By integrating the selection of materials and optimization of the process, the PP decorative film reaches the printing effect of a solvent-based ink, the printed product has no water mark, the texture is shallow and clear, natural and realistic and the PP decorative film is non-toxic and odorless and has excellent performances such as light resistance, scratch resistance, wear resistance, disinfection and sterilization; the preparation method is convenient and feasible in production processes, simple to operate and low in production cost, and is prone to industrial production.

Description

technical field [0001] The invention relates to a decorative film, in particular to a green and environment-friendly PP decorative film and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, people's demand for home decoration is increasing, and they are paying more and more attention to the quality of life, environmental protection and health.

At present, the decorative film used in the market for decorative home furnishing uses PVC (polyvinyl chloride) as the base material, and uses solvent-based ink to print the decorative layer. PVC film contains chlorine, which is unstable to light and heat, and will release toxic and harmful substances when burned; on the other hand, the melting point of PVC is ...

AI Technical Summary

Problems solved by technology

PVC film contains chlorine, which is unstable to light and heat, and will release toxic and harmful substances when burned; on the other hand, the melting point of PVC is 70°C, and it begins to soften at 40°C, so the oven temperature cannot exceed 50°C when PVC film is printed. The application of environmentally friendly water-based inks on PVC films is limited. The PVC decorative films printed with solvent-based inks will have solvent residues, and the products have peculiar smells, which are harmful to health
