Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of coatings, and particularly relates to a water-based glazing oil and a preparation method and application thereof. BACKGROUND

[0002] As an important part of logistics and commodity packaging, the anti-skid performance of cartons is directly related to the safety of commodities during transportation and storage. The anti-skid cartons on the current market mainly adopt the following technologies: physical anti-skid technology: such as surface concave-convex treatment, which increases the friction by changing the microstructure of the carton surface, but this method often leads to uneven appearance of the carton, affecting the appearance, and the anti-skid effect is greatly affected by humidity; chemical coating technology: using solvent-based or water-based anti-skid coating, which realizes anti-skid by forming a film layer with high friction coefficient on the surface of the carton, although the solvent-based anti-skid coating has good anti-skid effect, it has high VOC emission and poor environmental protection; while the water-based anti-skid coating is environmentally friendly, but the wear resistance and anti-skid effect are usually weak; composite material technology: composite of anti-skid particles and carton material to increase the surface roughness, but the cost is high and the composite process is complex.

[0003] In the use of water-based glazing oil, the existing technology mainly has the following problems: insufficient anti-skid performance: most water-based glazing oils cannot effectively increase the friction coefficient while improving the smoothness of the carton surface, resulting in poor anti-skid effect; poor wear resistance: the water-based glazing oil layer is easily worn under high friction or heavy pressure, affecting the anti-skid effect and service life of the carton; printing adaptability problem: the compatibility of some water-based glazing oils with printing ink is poor, affecting the printing quality, such as color loss, blurring and other problems; balance between environmental protection and performance: while pursuing environmental protection, how to ensure the anti-skid performance and wear resistance of the water-based glazing oil becomes a big challenge.

[0004] Therefore, it is of great significance to develop a water-based glazing oil printing technology that can significantly enhance the anti-skid performance of cartons, has good printing adaptability, and maintains environmental protection characteristics, to improve the overall performance of cartons and meet the market demand for safe, environmentally friendly and efficient logistics packaging.
