Abstract

The invention relates to coated paper and a preparation method thereof. The coated paper comprises a substrate and a coating material layer; and the coating material layer comprises the following components, in parts by weight: 45-75 parts of trifluoropropylmethylcyclotrisiloxane, 20-30 parts of polyethylene masterbatch, 16-28 parts of nano calcium carbonate, 6-8 parts of polyethylene wax, 2-8 parts of phenyl vinyl silicone oil, and 6-8 parts of starch glue. The coated paper provided by the invention has better moisture resistance and high-temperature resistance, higher peel strength and a larger application range.

Description

technical field [0001] The invention relates to the technical field of coated paper, in particular to a coated paper and a preparation method thereof. Background technique [0002] Existing coating processes generally employ the application of a thin layer of plastic to the surface of another plastic film or sheet, or more commonly to a non-plastic substrate such as paper, cellophane, or aluminum foil. Coating can be done from solutions, suspensions or melts. [0003] Coated paper is a composite material in which plastic particles are coated on the surface of paper through a casting machine. The main feature is that this composite material can be oil-proof, waterproof (relatively), and can be heat-sealed. LDPE is often coated on paper to make it heat-sealable, to resist moisture, and to protect the print from fraying. It is also commonly used on aluminum foil to create heat sealability and abrasion resistance, preventing the foil from interacting with the product. PVDC co...
