Description
Technical field
The present invention relates to mill base field, particularly a kind of dispersible pigment color paste for the inherent line toning of cultural paper pulp, top sizing and coating and preparation method thereof.
Background technology
All the time, Cultural Paper generally adopts basic-dyeable fibre and direct dyes to mix colours, basic-dyeable fibre bright in color light, low price, but there is fast light, poor heat resistance isostructuralism defect, so low side Cultural Paper can only be used for, the particularly low side wood-free paper of some mixing slurry systems; Although direct dyes are moderate, fast light heat resistance also can meet middle and high end Cultural Paper Production requirement, and in height white wood-free paper, particularly electro-photographic paper, brightness is on the low side, and coloured light is partially dark, significantly limit it and further develops.
In recent years, along with reaching its maturity of mechanical technique and dispersion technology, more American-European leading papermaking chemical product suppliers start to attempt use water-based pigment colour paste and carry out shading white paper, through the development of 3 to 5 years, product technology and application technology reach its maturity, and current domestic large-scale paper mill has adopted its dispersible pigment color paste produced to carry out Cultural Paper toning all.Compared with use dyestuff, use dispersible pigment color paste carry out mixing colours not only bright in color light, fast light heat resistance significantly to promote, particularly significantly can also reduce the use amount of fluorescent whitening agent in the toning of high blank sheet of paper, integrated cost has clear superiority.
In view of all advantages of dispersible pigment color paste, domestic chemical company also imitates one after another, but papermaking pigments mill base is different from papermaking dyestuff, also differ widely with common water-based pigment colour paste, its core technology is not only at product itself, more be equipment manufacturing technology and production control technology, so most product technology is difficult to reach paper mill demand, poor stability, particularly poor at the dilution stability that application aspect highlights, retention is not high, coloured light uniformity difference etc. defect be difficult to control.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Cultural Paper mix colours online with high look containing, low viscosity, high retention nano color paste, it is for toning, top sizing and coating in cultural paper pulp, and this product storage stability is high, and particularly water dilution rear stability is high, be applicable to different quality, arrange in pairs or groups with Microparticle Retention System and use, retention can reach more than 90%, and uses continuously through producer, coloured light remains consistent, has very strong applicability and higher cost performance.
