Abstract

The invention discloses a high-temperature-resistant water-based transfer coating and a preparation method thereof. , leveling agent. Among them: raw materials of transfer resin: 12-20% of acrylic resin, 2-6% of polymer of fumaric acid rosin, glycerol and pentaerythritol, 2-6% of urea, glyoxal and formaldehyde polymer, 8-6% of ethyl acetate 12%, n-propyl acetate 6-8%, polysiloxane resin 2-5%, absolute ethanol 8-11%, 2-hydroxyethylamine 3-4%, ammonia water 3-5%, distilled water 30-45% %. The present invention is mainly designed to prevent human saliva from corroding the printed coating. Water-based acrylic resin is selected, a variety of auxiliary agents are cross-linked and polymerized, and the polymer chains are cross-linked, and the linear structure is transformed into a network structure, which can significantly improve water resistance. And solvent resistance, mechanical strength and heat resistance are also improved.

Description

technical field

[0001] The invention relates to the technical field of film coating products, and more particularly to a high-temperature-resistant water-based transfer coating for transferring aluminized paper and a preparation method thereof. Background technique

[0002] Transfer aluminized paper, also known as transfer paper and vapor deposition paper, has metallic appearance, matt and bright varieties, excellent printing performance, degradable and recyclable environmental protection, etc.

[0003] The production process of transfer aluminized paper is to use biaxially oriented polyester film (PET) or BOPP film with a thickness of 0.02mm as the transfer substrate, and apply high temperature resistant water-based transfer paint; after vacuum aluminum plating, the aluminized surface is coated with After the cloth binder is compounded with 32-36g / ㎡ tobacco special tipping paper. At this time, the aluminized layer on the carrier film is bonded with the paper base, and the ...
