Description
Technical Field
The invention relates to the technical field of self-adhesive labels, in particular to a preparation process of friction-resistant varnish for self-adhesive labels.
Background
The self-adhesive label is provided with a self-adhesive layer and a printing layer for printing various information of the product; the self-adhesive label can be torn off from the base paper and stuck on corresponding commodity or package for marking, plays roles of display, beauty and practicability, and has wide application in various industries.
Because the labeling products are in the case of being in contact with each other and rubbed due to vibration in the transportation process, or the products and the packaging process, the patterns and texts of the self-adhesive labels can be ground and rubbed off, so that the self-adhesive labels have good friction resistance. In order to improve the abrasion resistance and weather resistance of the surface of the paper self-adhesive label, the most widely applied surface treatment process in the market is film coating and glazing. The film coating refers to coating a layer of transparent plastic film on the surface of a printed matter, wherein the main materials of the film coating are plastic films such as PP, PE and the like, and the plastic films are not degradable and recyclable and do not accord with the environment-friendly consumption concept. The glazing means that a layer of paint is coated on the surface of the printed matter, and a bright layer is formed on the surface of the printed matter after the paint is dried. From the perspective of energy conservation and environmental protection, the glazing is superior to the film coating, and many enterprises gradually replace the film coating technology with the glazing technology.
The aqueous gloss oil is a liquid coating prepared by taking water or ethanol as a carrier, waste materials generated in the production process can be biologically decomposed and recovered, the natural environment is not polluted, and the defects of toxicity and environmental pollution caused by taking an organic solvent as the carrier in the traditional solvent gloss oil are overcome. In addition, the aqueous varnish can be dried quickly, the quality of printing quality is stable, and the aqueous varnish is favored by consumers in the field of package printing. However, the domestic water-based gloss oil is relatively late to start, the performances such as glossiness, wear resistance and water resistance are bad, the gloss and luster of the label finished product cannot reach the expected effect, and the situation that the image-text part is rubbed and rubbed off in the transportation and storage process exists. The water-based varnish is used as an environment-friendly coating, has the characteristics of green safety, accords with the concept of green innovative development in the future development of the printing industry, is more densely and diversified in application, and has become an effort direction of the printing industry in improving and optimizing the formula of the water-based varnish. .
The most common domestic gloss oil is UV gloss oil, solvent type gloss oil and water-based gloss oil. The curing reaction of the UV gloss oil depends on the irradiation of ultraviolet rays to enable the inside of the gloss oil to undergo chemical reaction so as to be cured, and a printed matter has good gloss and weather resistance, but requires matched mechanical equipment and has high production cost; the solvent type gloss oil has the defects of easiness in volatilization, inconvenience for operators and environment, easiness in explosion, toxicity and environmental pollution; the water-based gloss oil takes water or ethanol as a solvent, the production process is pollution-free, and the finished product meets the requirement of environmental protection. The research on the water-based varnish in China is still in a theoretical stage, more imported water-based varnish is used, the price is high, and meanwhile, the domestic water-based varnish applied to the market has the problems of poor water resistance and wear resistance, easy generation of dry cracking after coating and the like, so that the wide application of the water-based varnish is limited to a certain extent.
Therefore, the water-based varnish with good friction resistance is researched, and a printing product with higher quality can be obtained by adjusting the component formula of the water-based varnish, so that the performance of the existing water-based varnish can be improved, and the production cost can be controlled within a reasonable range, so that the production service is better.
Based on the above, a preparation process of friction resistant gloss oil for the self-adhesive label is designed.
