A kind of high temperature resistant water-based transfer coating and preparation method thereof

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 ...

AI Technical Summary

Problems solved by technology

At present, the transfer coatings on the market mainly use oil-based transfer coatings or water-based transfer coatings. With the strengthening of people's awareness of environmental protection, oil-based transfer coatings have begun to fade out of the market. It is difficult to achieve the effect of oil-based transfer coatings in terms of performance such as durability. At present, the transfer coatings on the market are still mainly solvent-based.

Although some water-based transfer coatings achieve high temperature resistance by adding cross-linking agents before use, the effects of film-forming appearance, drying speed and printing adaptability are not ideal, and the addition of cross-linking agents may cause some follow-up problems, such as The hardening and deterioration of the paint in the feeding tank brings a lot of inconvenience to the process
