Self-initiated photocuring holographic transfer aluminized coating and preparation method thereof

Abstract

The invention provides self-initiation ultraviolet curing holographic transfer aluminizing paint and a preparation method thereof. The paint comprises, by weight, 35.7%-60% of an activated diluent, 35%-60% of a self-initiation low polymer, 0.2%-0.5% of a flatting agent, 0.5%-2% of an adhesion promoter and 2%-5% of an antistatic auxiliary. The activated diluent is acrylics. The self-initiation low polymer is acrylic resin. The adhesion promoter is a phosphate-modified acrylic acid auxiliary. The self-initiation low polymer, the activated diluent, the flatting agent, the adhesion promoter and the antistatic auxiliary are stirred, mixed, filtered and packaged to obtain the UV paint; and aluminizing compound paper is obtained through coating, aluminizing and compounding. The prepared paint has the beneficial effects that VOC residues are quite low and conform to the cigarette packet standard; the holographic effect is full and clear, and the aluminizing adhesion is very good; and potential hazards such as follow-up small molecule transfer and yellowing are not generated, and the self-initiation ultraviolet curing holographic transfer aluminizing paint can be used for food packaging and medicine packages.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a self-initiated photocuring holographic transfer aluminized coating and a preparation method thereof. Background technique [0002] UV curing technology has developed rapidly due to its advantages of high efficiency, energy saving, and low emission. Photoinitiators are important components in traditional photocuring systems. In order to overcome the ubiquitous oxygen inhibition problem in the free radical photocuring process, the The concentration of the photoinitiator in the film is generally much higher than the theoretical amount, and about 40-50% of the photoinitiator remaining in the cured film has not been decomposed after being irradiated by ultraviolet light. Residual photoinitiators and photolytic benzene-based fragments have problems such as penetration, migration, volatilization, and further photochemical reactions, which can easily lead to odor, toxicity, yellowing, ...
