Description

A kind of thin page printing paper coating composition
Technical field
This patent of invention belongs to papermaking chemical product field, particularly relates to a kind of thin page printing paper coating composition.
Background technology
Thin page printing paper refers to a class printing of light basis weight, high bulk, the same with other printings, in printing During, first page can expand broaden because print wet effect in surface absorbs the large quantity of moisture in ink, again can be because of during drying A large amount of evaporations of moisture and shrink, thus cause the error of printed dimensions；The fast heating drying system matched with high-speed paper machine, Because drying time is short, heat is big, the scale error that thin page printing paper can be caused this cause because of change of moisture content strengthens.
Summary of the invention
The present invention is directed to problems described above, it is proposed that a kind of thin page printing paper coating composition, this coating composition exists While possessing the high bulk of thin page printing paper, intensity and the deflection of thin page printing paper can be strengthened, reduce in printing process Scale error.
A kind of thin page printing paper coating composition, including following raw material:

Starch 30-50 part
Lubricant 10-15 part
Dispersant 0.3-1 part
Described nano-calcium carbonate microcapsule is with nano-calcium carbonate as capsule-core, and hydroxyethyl cellulose is that cyst wall prepares Microcapsule；
The preparation technology of described coating composition is: nano-calcium carbonate particles is dispersed in the ethanol solution of hydroxyethyl cellulose In, form stable suspension, be then spray-dried, form nano-calcium carbonate microcapsule；By 30-50 part starch, 0.3-1 Part dispersant joins stirring 5-10min in dispersion slot, adds 40-65 part nano-calcium carbonate microcapsule, 10-15 part lubricant, Continue stirring, be eventually adding 1-0.5 part microcrystalline Cellulose, obtain coating composition.
Described nano-calcium carbonate Microcapsules Size is 1-3 micron, is coated with one layer on described hydroxyethyl cellulose surface The degree of polymerization of thickness 1-5 nanometer is about 3000～5000 glucose molecule thin layers.
The core of described nano-calcium carbonate microcapsule and the ratio of wall material are (75-85): (15-25).
Described starch is modified starch, including Oxytarch, cationic starch, anionic starch.
Described lubricant is wax breast lubricant.
Described dispersant is sodium polyacrylate, number-average molecular weight 3500-4000 of described sodium polyacrylate, and viscosity is 2250-2300mPa.s。
Compared with prior art, the invention has the beneficial effects as follows:
1, the addition of nano-calcium carbonate microcapsule makes nano-calcium carbonate fill uniformly with to the porous void of page surface, makes white Spend finer and smoother, add its printability, add page rigidity, reduce the print caused because of the absorption of moisture and evaporation Brush scale error.
2, nano-calcium carbonate is as being coated with cloth filler, owing to it is Nano grade, and dispersion inequality in coating fluid preparation process Even meeting causes reunion, is made microcapsule structure, is not only beneficial to its dispersion, moreover it is possible to improve its retention effectively, by scraping The effect of cutter, can make cyst wall rupture, discharge nano-calcium carbonate, play improve paper surface evenness and to the absorbability of ink, Strengthen the effect of paper strength.
3, in coating, add microcrystalline Cellulose, interact with paper fibre, increase paper strength, and fill up paper table Space, face so that the paper surface after coating is smooth, roughness declines.The tensile strength of the paper after microcrystalline Cellulose is coated with It is better than uncoated paper with pop strength.
4, the degree of polymerization being coated with a layer thickness 1-5 nanometer on described hydroxyethyl cellulose surface is about 3000～5000 Glucose molecule thin layer, forms hydrogen bonded with microcrystalline Cellulose, improves the stability of coating composition.
