example 1

[0015] A method for making a matte laser anodized aluminum color coating, first weighing 97 parts by weight of acrylic resin resin for anodized aluminum and 3 parts of matte powder, mixing them, and then adding leveling powder to the mixture after mixing evenly The addition of leveling agent and defoamer is 5‰ of the total amount of the mixture, and then add ethyl acetate and / or butyl acetate solvent to prepare acrylic resin resin and matte powder for anodized aluminum Matte laser anodized aluminum color layer paint product with a weight content of 18%, the viscosity of the matte laser anodized aluminum color layer paint product is about 15s (coating 4# cup).

[0016] When coating and using, use 180-mesh anilox roll to coat on the PET film with release agent, then mold press, aluminum-plated, and glue layer to make anodized aluminum coating with matte laser effect. The coating is the highest The temperature is above 150°C, and the coating speed is 80m / min.

[0018] A method for making a matte laser anodized aluminum color coating, first weighing 98 parts by weight of acrylic resin resin for anodized aluminum and 2 parts of matte powder, mixing them, and then adding leveling powder to the mixture after mixing evenly Adding agent and antifoaming agent, leveling agent and antifoaming agent is 5‰ of the total mixture, and then add methyl ethyl ketone and / or butyl acetate solvent to prepare acrylic resin resin and matte powder for anodized aluminum Matte laser anodized aluminum color layer coating product with a content of 18%, the viscosity of the matte laser anodized aluminum color layer coating product is about 15s (coating 4# cup).

[0019] When coating and using, use 180-mesh anilox roll to coat on the PET film with release agent, then mold press, aluminum-plated, and glue layer to make anodized aluminum coating with matte laser effect. The coating is the highest The temperature is above 150°C, and the coating speed is 80m / min.

example 3

[0021] A method for making a matte laser anodized aluminum color coating, first weighing 96 parts of acrylic resin resin for anodized aluminum and 4 parts of matte powder and mixing them in parts by weight, and then adding leveling powder to the mixture after mixing evenly The addition of leveling agent and defoamer is 5‰ of the total amount of the mixture, and then ethyl acetate and / or n-propyl acetate solvent is added to prepare acrylic resin resin and matte for anodized aluminum A matte laser anodized aluminum color layer paint product with a powder weight content of 18%, the viscosity of the matte laser anodized aluminum color layer paint product is about 15s (coating 4# cup).

[0022] When coating and using, use 180-mesh anilox roll to coat on the PET film with release agent, then mold press, aluminum-plated, and glue layer to make anodized aluminum coating with matte laser effect. The coating is the highest The temperature is above 150°C, and the coating speed is 80m / min...

Abstract

The invention relates to a method for preparing a matt laser alumite chromatograph coating. The method comprises the following steps of firstly weighting 95-100 parts of alumite crylic acid resin ester and 2-5 parts of matt powder according to weight part and then mixing, adding a flatting agent and a defoaming agent after uniform mixing into the mixture, wherein the amount of the flatting agent and the defoaming agent is 3-7 per mill of the total amount of the mixture, then adding ethyl acetate, butyl acetate, butanone and / or n-propyl acetate solvent, and preparing the matt laser alumite chromatograph coating product containing 16-20% by weight of alumite crylic acid resin ester and matt powder. The matt laser alumite chromatograph coating can be used for matt treatment on the alumite chromatograph on dazzling laser packing, so that the pack can present a new appearance, the matt not only represents the change of angle of view, but also has more practical application. The matt laser alumite chromatograph coating has wide application prospect in packing field.

Description

technical field [0001] The invention belongs to the technical field of matte photoelectrochemical aluminum coatings, and relates to a method for preparing a matte laser anodized aluminum color layer coating applied in the field of packaging. Background technique [0002] Because of the laser holographic effect, laser anodized aluminum not only has the anti-counterfeiting function, but also has a good viewing angle impact effect, and has been widely used in the packaging field. However, the dazzling bright lasers on the entire package are easy to cause aesthetic fatigue, and occasionally matte treatment is used in some places, which can give people a refreshing feeling. Matte not only represents the change of viewing angle, but also has more practical applications, especially where laser marking is required, too much bright surface will affect laser marking instead, so it is necessary to perform matte treatment on the anodized aluminum color layer. The present invention is p...
