Benefits of technology

This technology makes it possible to create strong films with excellent quality at lower cost than traditional methods like electroplated or vacuum deposition techniques that require expensive equipment such as evaporation systems.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at removing unwanted coatings from partially treated (PEN) films during production processes like flexography. Current methods involve adding layers of lubricant before drying for precise placement onto the desired location. These techniques have drawbacks such as low yields caused by excessively wetting certain parts while leaving other parts uncovered, causing damage when dried without being cleaned afterwards, poor reproduction accuracy resulting from insensitive properties between different materials, potential contamination hazards associated with organic chemicals commonly found within food products, and long processing times required.

Embodiment Construction

[0008] This specific embodiment adopts the following technical scheme: the raw materials of the washing protection oil are composed of: 69%-75% of water-based epoxy resin, 0.7%-1% of water-based epoxy curing agent, 0.6%-0.8% of dispersant, talc Powder 25%-28%, Dafang white water 5%-9%, defoamer 0.1%-0.3%.

[0009] The defoamer adopts polyether defoamer.

[0010] The specific embodiment of water-washing protective oil and its preparation method: according to the formula, the water-based epoxy resin is uniformly dispersed in a high-speed disperser, and then the water-based epoxy curing agent and dispersant are mixed, and the water-based epoxy resin is mixed on a high-speed disperser with a rotating speed of 800-1400 rpm. Disperse for 30-50 minutes, and check the fineness of the mixture. When the fineness is less than or equal to 15um, add talcum powder and large anti-white water, adjust the speed of the disperser, and make the mixing system continue to mix at a speed of 300-500 for

Abstract

The invention discloses a novel water-washing protection oil and a preparation method thereof, and relates to the technical field of water-washing protection oil used in a process. The water-washing protection oil comprises the raw materials by mass: 69%-75% of water-based epoxy resin, 0.7%-1% of a water-based epoxy curing agent, 0.6%-0.8% of a dispersant, 25%-28% of a talcum powder, 5%-9% of diethylene glycol monobutyl ether, and 0.1%-0.3% of a defoaming agent. The water-washing protection oil is good in film-forming performance, low in viscosity, fast in drying speed, suitable for use in a packaging film local aluminum plating process, simple to use, and convenient and practical.
