AI Technical Summary

Problems solved by technology

Anodized aluminum coating products include full-scale transfer film, semi-transfer film, laser film, boiling-resistant film, bronzing film, etc., which can be used in high-end printing and packaging fields such as tobacco and alcohol. At present, there is a huge demand at home and abroad; however, due to the existing The stability, curability, and heat resistance of raw materials such as release agents, colorants, and adhesives used in products are not ideal, which greatly restricts the development of the anodized aluminum coating industry

Abstract

The invention discloses a parting agent and preparing method of electrochemical aluminium paint, which comprises the following parts: 100 parts of acetyl cellulose, 120-160 parts of methyl cellosolve and 720-800 parts of solvent through dissolving cellulose and diluting. The invention possesses good parting stability, which displays excellent property on the printable cloth and holographic moulding aspect.

Description

technical field [0001] The invention relates to functional film coating products, in particular to a release agent for anodized aluminum coatings and a preparation method thereof. Background technique [0002] Functional thin film coating products include thermal transfer carbon tape (TTR), multiple thermal conductive film (ACF) and anodized aluminum coating, etc. It is based on polyester film and coated with various coatings with different chemical properties of new materials. Thermal transfer carbon belt products are widely used in barcode printers, aircraft registration cards, train tickets, supermarket product labels and other fields that require fast scanning and identification. At present, all domestic products are monopolized by foreign products. A number of thermal conductive films are world-wide advanced technology products, widely used in the fields of microelectronics and high-performance liquid crystal displays, and currently only a few companies in Japan can pr...
