Abstract
The invention belongs to field of nanometer material technology, specially a kind of nano-calcium carbonate thickened pulp and preparation method thereof.The thickened pulp is made up of the average grain diameter of primary particle in below 50nm 15~20 parts of 0.3~0.6 part of 0.1~0.3 part of 5~10 parts of 100 parts of nano-calcium carbonate, organic inhibitor, rust resisting pigment, auxiliary agent, organic solvent；Each component is weighed in proportion, and organic inhibitor, rust resisting pigment, auxiliary agent are well mixed with organic solvent；Nano-calcium carbonate calcium powder is gradually added into during high speed dispersor is not stalled and moved, after all required nano-calcium carbonate calcium powders are added, is further continued for disperseing 5~30 minutes, dispersing speed is 1500~2500rpm；The nano-calcium carbonate slurry of gained is ground 1~10 hour in ball mill or sand mill, makes its average grain diameter below 100 nanometers, nano-calcium carbonate thickened pulp is obtained.The thickened pulp good dispersion, storage stabilization, solids content height, viscosity are low, compatibility is strong, have anti-corrosion function concurrently.
Description
Technical field
The invention belongs to field of nanometer material technology, specially a kind of nano-calcium carbonate thickened pulp and preparation method thereof.
Background technology
Nano-calcium carbonate is also known as super fine calcium carbonate, and the title of standard is calcium carbonate superfine powder.Nano-calcium carbonate application most into
Ripe industry is that plastics industry is mainly used in high-grade plastic products, can improve the rheological characteristic of plastic matrix, improve its mouldability.
There is toughened and reinforced effect as plastic filler, the bending strength and the modulus of elasticity in static bending of plastics is improved, heat distortion temperature and
Dimensional stability, while it is stagnant hot also to assign plastics.Nano-calcium carbonate is used to embody excellent dispersiveness in ink product
With transparent and fabulous gloss and excellent ink absorption and high drying property.Nano-calcium carbonate is made in resin type ink
Ink filler, good with stability, glossiness is high, the advantages of drying property strong adaptabilities of printing-ink are not influenceed.
Nano-calcium carbonate is a kind of Novel super-thin solid powder material grown up 1980s, its granularity between
Between 0.01~0.1 μm.Due to the fine of Nano particles of calcium carbonate, its crystal structure and Electronic Structure change,
Generate quantum size effect, small-size effect, skin effect and macroscopic quantum effect that ordinary calcium carbonate does not have.
It is good with resin compatible due to active nano-calcium carbonate surface oleophilic drainage, it can effectively improve or adjust product
Just, toughness, finish and bending strength；Improve processing characteristics, improve the rheological property of product, dimensional stability, heat-resisting
Stability has filling and enhancing, the effect of toughness reinforcing, can replace the expensive inserts in part and help Ji, reduces the use of resin
Amount, so as to reduce production cost, improves the market competitiveness.
As a rule, the successful use of Nano particles of calcium carbonate is strongly dependent on nano-particle and is scattered in liquid phase
Ability.Some special application fields, such as：Cosmetics, coating, weaving, polishing and catalysis etc., are required for particle to disperse well
And stably exist, it is impossible to which the phenomenon such as occur reuniting, and the activity of nano-particle could be shown well.It is such in order to meet
Need, someone is specialized in now and reapplied after how nano powder being prepared into the thickened pulp of high degree of dispersion.
The content of the invention
It is an object of the invention to provide a kind of nano-calcium carbonate thickened pulp and preparation method thereof, thickened pulp dispersiveness
Good, storage is stable, solids content is high, viscosity is low, compatibility is strong, and with anti-corrosion function.
The technical scheme is that：
A kind of nano-calcium carbonate thickened pulp, is counted by weight, and the thickened pulp is by the average grain diameter of primary particle in 50nm
Following 100 parts of nano-calcium carbonate, 5~10 parts of organic inhibitor, 0.1~0.3 part of rust resisting pigment, 0.3~0.6 part of auxiliary agent, have
15~20 parts of compositions of machine solvent；
Organic inhibitor is to nitro sodium laurate, to nitro potassium laurate, to nitro sodium palmitate, to nitro palmitic acid
Potassium, to nitro odium stearate or to nitro potassium stearate, molecular structure is as follows：
Wherein, M represents sodium ion or potassium ion, and R represents laurate, palmitic acid or stearic long-chain；
