Embodiment

[0026] Embodiment: oil-proof coated corrugated box and its preparation method

[0027] Participate in figure 1 As shown, the oil-repellent coated corrugated box is coated with a layer of oil-proof coating layer 1 on the inner surface of the corrugated box, and the oil-proof coating of the oil-proof coating layer 1 is partially pressed to the corrugated cardboard of the corrugated box by applying pressure Inside of original paper 3. Since the oil-repellent coating is pressed to the inside of the corrugated cardboard base paper 3 of the corrugated box by applying pressure, a bonding layer 2 is formed between the oil-repellent coating layer 1 and the corrugated cardboard base paper 3, so that the oil-repellent coating layer 1 and the corrugated cardboard The combination between base paper 3 is more tight.

[0028] The oil-proof coating is mainly composed of silicone-modified acrylic resin, water and surfactant, and the mass ratio is: 85:12:3; in other embodiments, a film-formin...

Abstract

The invention provides an oil-repellent coated corrugated case and a preparation method thereof. Firstly, the surface of one side of the body paper of a corrugated board adopted for the corrugated case is coated with oil-repellent coating; secondly, pressure is exerted to the oil-repellent coating under the condition of a temperature ranging from 160 to 170 DEG C so that the oil-repellent coating can be partially pressed in the body paper of the corrugated board, and the rest part of the oil-repellent coating forms an oil-repellent film on the surface of the body paper of the corrugated board. The oil-repellent coated corrugated case is an environment-friendly product, and does not contain heavy metal and does not pollute the environment; the oil-repellent coated corrugated case can be recycled and reutilized to conform to the European Union RoHs decrees. The case is coated with a layer of imported oil-repellent coating, and when the coating amount is about 15g/m<2>, the penetration of oil can be thoroughly obstructed, and a remarkable effect can be achieved and the cost is low.

Description

technical field [0001] The invention relates to an oil-proof coated corrugated carton and a preparation method thereof, belonging to the technical field of packaging products. Background technique [0002] In daily production and life, in addition to packaging substances with high water content, we also often pack many oily substances, such as fast food such as hamburgers and pizza, mechanical parts coated with anti-rust oil and lubricating oil, etc. The materials used to package these substances must have good oil resistance. Polyethylene, polypropylene, polystyrene, polyvinyl chloride and other film packaging are commonly used in the market. These synthetic polymer materials are difficult to degrade in nature. The waste after use has caused great pollution to the human environment. Moreover, the labor cost is large and the packaging cost is high during packaging. With the continuous strengthening of people's awareness of environmental protection, such non-degradable plas...
