Embodiment 1

[0013] The UV iron printing primer described in the first invention, the weight ratio of the UV iron printing primer is: 50% modified acrylate, 10% photoinitiator, 10% rutile titanium dioxide, 2% dispersant, functional monomer 28%. The sum of the percentages of the above components is 100%. The modified acrylate is aliphatic urethane acrylate (PUA), using CYTEC, SARTOMER, Changxing Chemical, Sanki Chemical or their mixtures. The functional monomers are CYTEC, SARTOMER, Changxing Chemical, Sanki Chemical or their mixtures; for example: IBOA, HEA, PETA, etc. The rutile titanium dioxide is DuPont, Tenor, Sichuan Longmang or their mixtures, such as R906, CR828, R996, etc. The dispersant is acidic group-containing copolymer solution, block copolymer solution or their mixture, such as: BYK103, BYK110, BYK111, tego685, tego655, etc. The photoinitiator is 1-hydroxymethyl cyclohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenyl-1-propanone, acyl phosphine or their mixture, such as: 117...

Embodiment 2

[0021] The UV iron printing primer described in another invention, compared with Example 1, only changes the composition of the UV iron printing primer, and the weight ratio of the UV iron printing primer is: 60% modified acrylate, functional single Body 35%, rutile titanium dioxide 0%, dispersant 0%, photoinitiator 5%. After testing, the obtained UV iron printing primer meets the requirements.

Embodiment 3

[0023] The UV iron printing primer described in another invention, compared with Example 1, only changes the composition of the UV iron printing primer, and the weight ratio of the UV iron printing primer is: 45% modified acrylate, functional single Body 27%, rutile titanium dioxide 20%, dispersant 1%, photoinitiator 7%. After testing, the obtained UV iron printing primer meets the requirements.

Abstract

The invention discloses ultraviolet (UV) metal decorating base oil. The UV metal decorating base oil consists of the following components in percentage by weight: 30 to 60 percent of modified acrylic ester, 5 to 10 percent of photoinitiator, 0 to 40 percent of rutile type titanium dioxide, 0 to 2 percent of dispersing agent, and 15 to 35 percent of functional monomer, wherein the total weight percentage of all the components is 100 percent, the modified acrylic ester is aliphatic polyurethane acrylate, and the photoinitiator is 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenyl-1-propanone, and acyl phosphonates or a mixture thereof. The UV metal decorating base oil has the advantages of high flexibility, adhesion, impact resistance, boiling resistance, no mobility, capacity of meeting the requirement of metal post-processing, high production efficiency, and obvious energy-saving and emission-reducing effect, and can be used for outer coating of food and beverage cans and industry packaging barrels and cans.

Description

technical field [0001] The invention relates to a UV curing metal coating, in particular to a UV iron printing base oil with good flexibility, good adhesion, good impact resistance, good cooking resistance and no migration. Background technique [0002] Metal surface printing, commonly known as iron printing, generally includes the following methods: primer, ink printing, and varnish. At present, solvent-based coatings are used for primers, which need to be cured after high-temperature baking in an environment above 150°C, which results in high energy consumption and heavy pollution. Contents of the invention [0003] In order to overcome the problems of high energy consumption and heavy pollution of traditional solvent-based iron printing primers, the purpose of the present invention is to provide a UV iron printing primer, which has good flexibility, good adhesion, good impact resistance, and good cooking resistance , No migration, can adapt to the needs of metal post-p...
