preparation example Construction

[0023] The preparation process of aluminum strips for cigarette pack ink is as follows:

[0024] 1) Mix the raw materials in the following mass percentages evenly: 30% to 80% of solvent, 0.1% to 3% of initiator, 10 to 50% of aluminum paste, 5 to 30% of A component and 1 to 10% of B component. The A component is used to provide free acrylic acid and / or acrylate, and the B component is used to provide cellulose functional molecules;

[0025] 2) First raise the temperature to 15°C, let the mixed material react for 8 hours, then raise the temperature to 40°C, let the mixed material continue to react for 3 hours, part of the free acrylic acid and / or acrylate in the solution cooperates with the cellulose functional molecules to carry out the reaction on the surface of the aluminum sheet Functional modification, the remaining acrylic acid and / or acrylate undergoes free radical polymerization on the surface of the aluminum sheet, and the polymer formed after free radical polymerizatio...

Embodiment 1

[0029] The process of preparing ink aluminum strips in this embodiment is as above, specifically, the raw materials include 40% of n-propyl acetate, 1% of benzoyl peroxide, 29% of aluminum paste, 2% of cellulose acetate butyrate, 8% of methacrylic acid %, butyl acrylate 10%, hydroxypropyl methacrylate 10%.

Embodiment 2

[0031] The process of preparing ink aluminum strips in this embodiment is as above, specifically, the raw materials include 60% of n-propyl acetate, 3% of dibenzoyl peroxide, 30% of aluminum paste, 2% of cellulose acetate propionate, methacrylic acid 1%, butyl acrylate 2%, hydroxypropyl methacrylate 2%.

Abstract

The invention provides an aluminum strip for cigarette package ink. A preparation process is as the follows: under a heating condition, carrying out functionalization modification on a surface of an aluminum sheet by cooperation of partial free acrylic acid and / or acrylic acid ester in a solution and cellulose functional molecules, carrying out a free radical polymerization reaction on residual acrylic acid and / or acrylic acid ester on the surface of the aluminum sheet to form a polymer serving as molded resin, and carrying out pressure filtration, hydraulic extrusion molding and vacuum staticbaking on the materials to obtain the aluminum strip. The preparation raw materials comprise a solvent, an initiator, aluminum paste, a component A and a component B, wherein the component A comprises at least one selected from hydroxypropyl methacrylate, methyl methacrylate, hydroxyethyl acrylate, isobornyl acrylate, butyl acrylate and methacrylic acid, and the component B comprises at least oneselected from cellulose acetate butyrate, cellulose acetate propionate and cellulose nitrate. According to the invention, functionalization of the surface of the aluminum sheet and one-step generation of the molded resin are realized, and the aluminum strip product has excellent metal effect, striping property and printing adaptability.

Description

technical field [0001] The invention belongs to the technical field of metal pigments and inks, and in particular relates to a method for preparing aluminum strips that utilize cellulose functional molecules, acrylic acid and / or acrylic acid esters for surface modification, and the aluminum strips prepared by the method that can be used for cigarette pack inks Aluminum bar products. Background technique [0002] With the progress and development of society, people pay more and more attention to their own health and environmental safety. Therefore, the state restricts and manages the use of hazardous substances in the packaging and decoration industry. The new domestic cigarette label industry standard "Safety and Sanitation Requirements for Cigarette Rod and Packing Paper" was officially implemented in the second half of 2016, mainly targeting volatile organic compounds (VOCs), benzene series, and phthalates (increased Plastics), specific aromatic amines, photoinitiators an...
