Abstract
The invention discloses a method for using attapulgite to prepare ink filling material, which belongs to natural mineral resources utilization technology field, wherein the attapulgite is used as raw material, and the powder attapulgite ink filling material is obtained by material selection, drying, ultrafine airflow mill, and surface modification treatment. The invention selects natural nonmetal mineral attapulgite as raw material to prepare ink filling material, which makes full use of natural resources. The invention has simple preparation technology and equipment requires, no pollution produced during process, so the invention can protect the environment, and the filling material can concurrently work as thickener to obviously improve the flowablitity, stability and color strength of the ink.
Description
Technical field
The invention belongs to the technical field of utilizing of natural mineral resource attapulgite clay (hereinafter to be referred as recessed soil), be specifically related to prepare the method for ink filling material with recessed soil.
Background technology
Usually add stopping composition during printing ink is produced,, reduce the cost of printing ink simultaneously as extender to adjust flowability, tinting strength, opacifying power and the gloss etc. of printing ink.Stopping composition commonly used is mineral compound such as aluminium hydroxide, barium sulfate, gloss white and calcene in printing ink at present.
Recessed soil is a kind of silicate of rich magnesium, its molecular formula Mg

2O, thus give its very high use value because of its special fibrous crystalline structure and the special property that had, the dispersiveness that recessed soil is good, adsorptivity and colloidal property make it possess as the printing ink filler may.
Summary of the invention
The objective of the invention is to: provide the recessed soil of a kind of usefulness to prepare the method for ink filling material, adopt this method to produce the recessed native ink filling material of powdery, the recessed native ink filling material of this powdery not only can be adjusted flowability, tinting strength of printing ink etc., and can be used as the thickening material of printing ink, significantly improve the stability of printing ink, expand the Application Areas of recessed soil.
Technical scheme of the present invention is that the method that the recessed soil of this usefulness prepares ink filling material specifically is made up of following steps:
1, select materials: the recessed soil of screening purity＞75%, whiteness＞80 is raw material, and the recessed native impurities of this raw material is mainly polynite, wherein rhombspar, quartz or opaline content≤5%, the recessed native raw material moisture of natural drying in the sun＜12%;
2, oven dry: the recessed soil that will screen is transported in the dryer dries, and bake out temperature is controlled at 200-250 ℃, oven dry back moisture＜2%;
3, pulverize: the recessed native raw material that will dry is transported in the superfine jet mill, remove the great impurity of hardness height ratio such as quartz contained in the recessed soil, rhombspar, opal through comminution by gas stream and by classification, obtain the recessed native powder of foreign matter content≤1%, granularity＜2.7 μ m;
4, surface modification: recessed native powder conveying in high-speed mixer, is added TM-200s a flat iron plate for making cakes mould assembly titanate coupling agent, and the coupling agent consumption is the 0.4-3.0% of recessed native weight, high-speed mixing 15-20 minute, obtains the recessed native ink filling material of powdery.
The invention has the advantages that:
1, preparation technology and equipment requirements are simple.
2, selecting the recessed soil of natural nonmetalliferous ore is raw material, has made full use of natural resources, and the course of processing do not produce environmental pollution, has protected environment.
3, the recessed native ink filling material of this powdery can significantly improve the flowability of printing ink, the stability and the tinting strength of raising printing ink.
