A kind ofly promote auxiliary agent of compound ivory board printing performance and preparation method thereof
Technical field
The present invention relates to pulp technology for making paper, particularly a kind of compound ivory board that promotes prints auxiliary agent of absorbency and preparation method thereof.
Background technology
Paper is that the mankind learn, work, one of indispensable important articles for use of living, traditional papermaking to bring the destruction of high degree due to the three wastes that produce in overcut trees and traditional paper industry production technique to ecotope, the cry that the feature of environmental protection of people to papermaking starting material used and the paper product course of processing requires is more and more higher.Compound ivory board, i.e. stone paper are a kind of type materials between paper and plastics, and both alternative traditional part functionalities paper, professional paper, can substitute again traditional most of plastic packing article.And have the advantages that cost is low, controllability is degraded, can save a large amount of costs for user, and can not produce pollution, be the important substitute replacing traditional plant fibrous paper.
The oil absorbency of paper affects its important printability index as print quality.Owing to containing a large amount of non-polar component in stone paper, be difficult to attachment and printing, usually need special ink, improve the cost of printing, and namely use special ink, ink attachment fastness is also undesirable, paper is too little to absorption of inks ability, then the rate of drying of the printing product surface ink that can slow down, and print speed slows down, cause printed matter set-off simultaneously, especially for by the dry letterpress of infiltration and high speed printing more very.In addition, adopt the paper that ink receptivity is poor, after its inking, ink sorptive performance is also poor.And then improving the absorbency of stone paper and the printing performance such as antistatic, is an important topic in stone paper R&D and production process.
In prior art, China Patent Publication No. 101768893A discloses a kind of stone paper coating and production method, this coatings is formed a kind of new stone paper on the stone paper films such as PP, BOPP, PVC, PET, general mode of printing and general ink can be applicable to.But those skilled in the art are in implementation process, find to occur the phenomenon that paint aging comes off affecting printing effect in coatings inequality and stone paper use procedure.
China Patent Publication No. 102363572A discloses a kind of functional additive for stone paper, functional adsorption group is introduced by grafting after carrying out chemistry and physically modified to nano silicon and nano alumina surface, after additive application is in stone paper, on the surface of paper with ink affinity group, enhance the adsorptivity in stone paper printing process, improve the printing quality of stone paper.But, those skilled in the art find in implementation process spherical nano silicon and nano alumina surface smooth, although introduce blotting group, because blotting group long-term exposure is in air, the microbes corrosion blotting group of electrostatic adhesion, cause ink easily aging, coming off of coating, affects printing quality.
Summary of the invention
In order to solve compound ivory board difficult attachment and printing in printing process, need special ink and in printing process, also there is the large defect of electrostatic, the absorbency of further raising compound ivory board in printing process, the embodiment of the present invention provides a kind of auxiliary agent and the preparation method that promote compound ivory board printing performance, by adopting the ZnO nano acanthosphere particle after preparing surface modification, there is siphon microstructure, adopt promoting agent to carry out chemical surface modification, and then the present invention can improve the absorbency of compound ivory board further simultaneously.
