A kind of metal base high-performance and low-cost UV-curable water-borne ink
Technical field
The present invention relates to technical field of ink, particularly relate to a kind of metal base high-performance and low-cost UV-curable water-borne ink.
Background technology
UV-curing technology is since coming out, because it has the feature of 5E, i.e. efficiently (Efficient), applicable wide (Enabling), economical (Economical), energy-conservation (Energy Saying), environmental friendliness (Environmental-friendly).In the prior art, UV-curing technology has been widely used in by people and has lived closely bound up field, beautifies object and the effect of protection object to play.
Ultraviolet light radically curing system, ultraviolet light Cationic curing systems and ultraviolet light free radical-cationic hybrid curing system can be divided into according to the different UV-curing technologies of initiator system.It is fast that radical UV curing system has curing rate, and performance such as can easily be accommodated at the advantage, but there is problems such as shrinking serious, oxygen inhibition, adhesive ability difference.Cationic curing systems development is later, it has, and volume contraction is little, adhesive force is strong, wear-resisting, hardness advantages of higher, but it also has that curing rate is slow, oligomer and reactive diluent kind few, price is high, cured product performance is difficult to the shortcomings such as regulation, thus limits its actual application.Therefore from ultraviolet light free radical-cationic hybrid curing system, can maximize favourable factors and minimize unfavourable ones the most theoretically, the advantage giving full play to free radical and Cationic curing systems, widen the range of photocuring system.
Summary of the invention
The present invention is directed to above-mentioned background technology, it is provided that a kind of metal base high-performance and low-cost UV-curable water-borne ink.
For realizing the object of the invention, the technical solution used in the present invention is as follows:
A kind of metal base high-performance and low-cost UV-curable water-borne ink, it is characterised in that: count by weight, be prepared from the following materials: bisphenol A epoxide resin list isobornyl acrylate mixes prepolymer: 50 ~ 60 parts;Pigment: 1 ~ 2 part;Photoepolymerizationinitiater initiater: 2 ~ 5 parts;Reactive diluent: 10 ~ 20 parts;Defoamer: 1 ~ 5 part;Aqueous solvent: 100 ~ 120 parts;
The preparation method that described bisphenol A epoxide resin list isobornyl acrylate mixes prepolymer comprises the following steps: by bisphenol A epoxide resin and p methoxy phenol, isobornyl acrylate mix and blend, it is heated to 80 ~ 90 DEG C, it is slowly added to acrylic acid, stirs 1 ~ 2h, to obtain final product.
Further, described a kind of metal base high-performance and low-cost UV-curable water-borne ink is counted by weight, is prepared from the following materials: bisphenol A epoxide resin list isobornyl acrylate mixes prepolymer: 55 parts;Pigment: 1.5 parts;Photoepolymerizationinitiater initiater: 4 parts;Reactive diluent: 15 parts;Defoamer: 3 parts;Aqueous solvent: 100 parts.
Further, described reactive diluent is hydroxy-ethyl acrylate or hydroxyethyl methacrylate.
Further, described Photoepolymerizationinitiater initiater is benzoin methyl ether, benzoin ethyl ether or said mixture.
Further, described defoamer is polysiloxanes silicones.
Further, described aqueous solvent is ethanol and water mixed solvent.
Present invention also offers the preparation method of above-mentioned a kind of metal base high-performance and low-cost UV-curable water-borne ink, comprise the following steps: bisphenol A epoxide resin list isobornyl acrylate is mixed prepolymer, reactive diluent, pigment, defoamer, aqueous solvent mix and blend, it is heated to 40 ~ 50 DEG C, maintain 2 ~ 3h, add Photoepolymerizationinitiater initiater, stirring 0.5 ~ 1h, to obtain final product.
The invention provides a kind of metal base high-performance and low-cost UV-curable water-borne ink, have the beneficial effect that:
One metal base high-performance and low-cost UV-curable water-borne ink of the present invention, have employed ultraviolet light free radical-cationic hybrid curing system, occur radical UV curing reaction and cation photocuring to react in same system simultaneously, at aspects such as light-initiated, Volume Changes is complementary, property regulation, there is preferable cooperative effect.The present invention has solvent resistance and the adhesive force of excellence, and overall performance is superior, low cost, it is adaptable to all kinds of construction substrate.
