Description
Technical Field
The invention belongs to the technical field of digital printing materials, and particularly relates to an ink-absorbing coating.
Background
Digital printing is a comprehensive technology developed on the basis of printing technology, takes electronic texts as carriers, and transmits the electronic texts to digital printing equipment through a network to realize direct printing. The improvement of digital printing equipment in printing quality, speed and range of printing stock is not separated from the development of digital printing materials, especially digital ink and powdered ink. The quality of digital printing depends largely on the nature of the printing material, in addition to the nature of the printer, the ink. The printing material comprises a main material layer and an auxiliary material layer, wherein the main material layer comprises a base material, primer and an ink absorbing layer, and the auxiliary material layer comprises an auxiliary material and a release agent. The core technology of the main material layer is a coating paint formula, which is required to be capable of absorbing ink well and displaying images.
Ink-receptive coatings are largely classified into three categories: swelling type ink-absorbing coating, gap type ink-absorbing coating and cast coating highlight type ink-absorbing coating. The gap type ink-absorbing coating mainly comprises resin, pigment particles and an auxiliary agent, wherein the pigment particles are the most important components, and silicon dioxide and aluminum oxide are mainly used at present. The resin is used as a carrier of pigment particles, and the pigment particles are uniformly distributed on the surface of the resin after film formation to form a network containing a large number of micropores, so that the ink is absorbed and fixed. The gap type ink-absorbing coating has good ink absorption, good ink fixing property and high image resolution, and is a main development direction of the color printing ink-absorbing coating in the future.
However, the basic performance of the coating should be considered, and the existing ink-absorbing coating cannot reasonably design resin and pigment particles, so that the basic performance and the ink-absorbing performance of the coating cannot be considered well.
In summary, how to design an ink-absorbing coating layer, which can improve the basic performance and ink-absorbing performance of the coating layer at the same time, is a problem that needs to be solved at present.

On the basis of the embodiment 1, the nano silicon dioxide is pretreated in the embodiment 2, and the ink absorption and ink fixing performances of the nano silicon dioxide are improved, but the basic performances of the coating are reduced because the composite emulsion is easy to generate maldistribution after being mixed with the pretreated nano silicon dioxide. On the basis of the embodiment 2, the embodiment 3 improves the dispersing effect and improves the dispersing effect, so that the basic performance, the ink absorption and the ink fixing performance of the ink absorption coating are all obviously improved.
Comparative examples 1 to 3 each changed the composition of the composite resin emulsion compared with example 3, and all properties thereof were affected. Comparative examples 4 and 5 changed the pretreatment method of nanosilica compared to example 4, and although the basic properties of the coating were not significantly affected, the ink absorption and ink fixation properties were reduced. Comparative examples 6 to 10 each changed the components of the dispersant and the method of use, respectively, compared with example 5, and as a result, all properties were affected.
