Embodiment 1

[0051] 24kg hydroxypropyl methacrylate, 5.2kg acrylic acid, 45kg styrene, 69.8g methyl methacrylate, 16kg acrylonitrile, 2kgBPO, 70kg butanone, 26kg ethyl acetate and 46g butyl acetate were added to the reactor, Then the temperature was raised to 90° C., and after 2 hours of heat preservation, BPO ethyl acetate solution (prepared by dissolving 1 kg of BPO in 13 kg of ethyl acetate) was added for 10 to 20 minutes. After continuing to keep warm for 2 hours, add an equal amount of BPO ethyl acetate solution, and then keep warm for 6 hours. Finally, 72kg of butanone was added, the temperature was lowered and cooled, and the material was discharged to obtain an acrylic resin.

Abstract

The invention discloses an information level resin for alumite and a preparation method of the alumite as well as an alumite stamping foil. The preparation method of the information level resin for alumite comprises the following steps: adding an acrylate monomer, first part of a first solvent and partial initiator, heating to a temperature required by a reaction, and insulating to react; dissolving the rest initiator into second part of the first solvent, additionally filling the mixture into a reaction kettle twice; carrying out heat preservation to react for 6-8 hours after the initiator is completely filled; stopping heating, additionally filling third part of the first solvent, and cooling to obtain acrylic acid resin; adding an additive into the acrylic acid resin, diluting with a second solvent to form glue liquid with solid content of 15-25 percent. The information level resin is mainly applied to products of which the stamping base material is tobacco packet tipping paper, and has the advantages that VOCS can achieve the requirement of tobacco packets, the solvent resistance and abrasion resistance of the information level resin are better than those of products in current market, and the information level resin has long service life.

Description

technical field [0001] The invention relates to the field of functional films, in particular to an information layer resin used for anodized aluminum, a preparation method thereof, and an anodized aluminum hot stamping foil. Background technique [0002] Anodized aluminum hot stamping foil is a hot stamping material made by coating and vacuum aluminizing on a film substrate. It is a common printing consumable. Bronzing graphics have dazzling and magnificent visual effects, and have been widely used in various industries such as clothing, paper, plastic, glass, electronic appliances, toys, gifts and handicrafts. The existing anodized aluminum is a hot stamping material formed by a certain coating process on a polyester film to form four layers of coatings. These coatings are from bottom to top respectively a release layer, a colored layer, an aluminum layer, and an adhesive layer. Among them, the coloring layer resin (namely, the information layer resin) is often prepared by...
