Environmentally-friendly dope for solidifying direct-vacuum aluminized paper by electron beam and preparation method thereof

Abstract

The invention discloses an environmentally-friendly dope for solidifying direct-vacuum aluminized paper by an electron beam and a preparation method thereof. The preparation method comprises the following steps of: weighing 10-90 parts of epoxy resin, 5-30 parts of epoxy active diluents, 2-5 parts of initiators; agitating the epoxy active diluents and raising the temperature to 50-60 DEG C; adding the epoxy resin, agitating for 30 min; adding the initiators, filtering after uniform agitating and obtaining the required environmentally-friendly dope for solidifying the direct-vacuum aluminized paper by the electron beam. The dope has moderate viscosity and can be applied to prime coat and surface coating processes of the direct-vacuum aluminized paper; and compared with a dope layer of a traditional dope, a dope layer solidified by the electron beam is more greatly improved in temperature tolerance and flexibility, and the anti-burst performance during the bending of the direct-vacuum aluminized paper is improved.

Description

technical field [0001] The invention belongs to the technical field of radiation curing coatings, in particular to an environment-friendly electron beam curing coating for direct vacuum aluminized paper. At the same time, the invention also relates to a preparation method of the paint. Background technique [0002] Cigarette rod and box wrapping paper and cigarette inner lining paper are extremely important packaging materials for cigarettes. The vacuum aluminum plating technology used in domestic cigarette materials is divided into two types according to the production process (transfer method) and (direct plating method). That is what people often say transfer paper and direct plating paper. In the production process of the transfer method, PET or BOPP film needs to be used as a carrier, vacuum aluminum-plated on the film and then transferred and compounded with paper, and the film is peeled off after long-term curing. It inevitably uses a large amount of volatile solven...

Problems solved by technology

[0005] At present, there are still two urgent problems to be solved in the curing of epoxy resin by cationic mechanism: one is that the viscosity of the solvent-free epoxy resin system is relatively high, resulting in poor leveling of the coating; the other is that bisphenol A epoxy resin is cured by electron beams. Insufficient post toughness, the coating is easy to burst
