Problems solved by technology

Traditional release materials are silicone oil, OP wax, etc. These materials have very low surface tension and cannot meet the requirements of printing on their surfaces, so there is an urgent need to develop new printable release materials
[0005] At the same time, the carriers of existing release materials are mostly organic solvents such as toluene and butanone, which have a great impact on the environment and human body.
Extensive use of such solvents will not only harm the health of operators, but also pollute the environment as organic solvents are discharged into the atmosphere.

Embodiment Construction

[0016] The embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings. Take the production of 100 kg of this printable high-peelability environmentally friendly anodized aluminum release material as an example.

[0017] The first step is to weigh 50 kilograms of solvent and put it into the material vat, turn on the heating, set the temperature to 75 degrees Celsius, start stirring when the temperature of the solvent in the vat rises to 75 degrees Celsius, and put 20 kilograms of polymethacrylic resin into it, and speed up Stirring speed, so that the material liquid is heated evenly.

[0018] In the second step, when the resin in the material tank is completely dissolved, the stirring speed is reduced, the heating temperature is set to 60 degrees Celsius, and 5-10 kilograms of acrylic resin with hydroxyl groups are dropped in. The acrylic resin with hydroxyl group is blended with polymethacrylic resin during the disso...

Abstract

The invention discloses a printable environment-friendly electric aluminium release type material with high strippability. The material has the advantages of good strippability, excellent trimming performance, few influence on environments during production and usage processes, short production period, and wide application to cold stamping films and hot stamping films. The material is prepared by the following steps: 1. polymethacrylic resin is added into a solvent with stirring, after dissolving, acrylic resin with hydroxyl is added with stirring, and a blended resin solution is obtained; 2. an additive is added into the solvent with stirring in order to obtain an additive solution; 3. the stirred blended resin solution and the additive solution are blended, a solvent is added with stirring, after stirring, a 200 mesh filter bag is used for filtering, and the printable environment-friendly electric aluminium release type material with high strippability is prepared.

Description

technical field [0001] The invention relates to the technical field of packaging and printing, in particular to an anodized aluminum related to hot stamping and cold foil for label printing and commercial printing. Background technique [0002] In the fierce market competition, in order to increase the added value of products and carry out packaging anti-counterfeiting more effectively, more and more packaged goods adopt anodized aluminum hot stamping technology. Anodized aluminum hot stamping technology is closely related to the packaging market. The packaging design of high-quality anodized aluminum hot stamping film makes the product bright and beautiful, and improves the anti-counterfeiting and value of the packaging. The early anodized hot stamping film technology was dominated by hot stamping film, and the new generation of hot stamping film technology represented by UV cold stamping film has developed rapidly in recent years and is widely used in flexographic printing...
