Abstract
The invention discloses a flexible UV curing offset printing ink which is characterized by being prepared from the following raw materials in parts by weight: 1-3 parts of an organic pigment, 15-18 parts of methyl methacrylate, 1-2 parts of titanium sulfate, 2-3 parts of nano titanium dioxide, 2-4 parts of tricresyl phosphate, 11-15 parts of methyl methacrylate, 12-14 parts of trimethylolpropane triacrylate, 1-1.1 parts of cobalt naphthenate, 5-8 parts of a 1173 photoinitiator, 1-2 parts of monobutyltin oxide, 3-4 parts of polyethylene wax, 1-2 parts of an antiager A1, and 4-5 parts of an assistant. The assistant improves the flexibility of printing ink, enables the printing ink to be uniformly dispersed, and maintains the stability of the printing ink. The printing ink has good flexibility, and has the characteristics of quick drying, economization and environmental protection.
Description
Technical field
The present invention relates to a kind of ink and preparation method thereof, particularly a kind of flexible UV cured offset printing ink and preparation thereof are sent out.
Background technology
Ultraviolet light polymerization (UV) ink refers under uviolizing, utilizes the UV-light of different wave length and energy to make ink film forming and dry ink.Utilize different UV spectrum, can produce different-energy, the monomer polymerization in different ink vehicles is become to polymkeric substance, so the look film of UV ink has good machinery and chemical property.The major advantage of UV ink has: (1) is without solvent; (2) rate of drying is fast, and power consumption is few; (3) good luster, bright in luster; (4) water-fast, resistance to solvent, wear resisting property is good.In UV ink, light trigger is a kind of light activated compound that is subject to, and after absorb light is shone, is excited into free radical, and energy is transferred to photosensitivity molecule or photocrosslinking agent, makes UV China ink that photocuring reaction occur.UV China ink has become a kind of more ripe ink technology at present, and its pollutant emission is almost nil.Except not containing solvent, UV China ink is also just like being difficult for scumming, and site is clear, the bright-coloured light of mass colour, the advantage such as chemical resistance is excellent, low-consuming.Along with scientific and technological development, the various aspects of performance of ink has had very large improvement; But still exist its ink-water balance, pigment wetting, viscosity, snappiness etc. can not meet the defect of high speed printing, especially for extra package industries such as tobacco bale, plastics films, can not meet also very fast requirement of curing speed when thering is high-flexibility very.
Summary of the invention
The object of this invention is to provide a kind of flexible UV cured offset printing ink and preparation thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
A flexible UV cured offset printing ink, is made by the raw material of following weight part: pigment dyestuff 1-3, methyl methacrylate 15-18, titanium sulfate 1-2, nano titanium oxide 2-3, Tritolyl Phosphate 2-4, methyl methacrylate 11-15, Viscoat 295 12-14, cobalt naphthenate 1-1.1,1173 light trigger 5-8, Mono-n-butyltin 1-2, polyethylene wax 3-4, antioxidant A 1-2, auxiliary agent 4-5;
