Abstract
The invention discloses a preparation method of modified attapulgite clay. The preparation method includes adding attapulgite clay raw ore into a crusher to be crushed, squeezing and pressing the crushed attapulgite clay by utilization of a roller to obtain sheet attapulgite clay having a thickness of 2-3 mm, adding the sheet attapulgite clay into a kollermill, adding alumina and aluminium hydroxide and mixing uniformly, squeezing and pressing by utilization of the roller again, pulping, filtering, dehydrating, drying and smashing to obtain the modified attapulgite clay. The method is simple in operation and low in production cost, and the modification effect of the product is good.
Description
Technical field
The present invention relates to a kind of preparation method of modified attapulgite clay.
Background technology
Attapulgite is called green attapulgite, Palygorskite, be a kind of layer of chain-like structure containing the rare clay mineral of Shuifu County's zeopan, crystal proterties is bar-shaped, needle-like, fibrous, (μ m) for long 0.5-5 micron, (μ m) for wide 0.05-0.15 micron, be 2: 1 type clay minerals, i.e. two-layer silicon-oxy tetrahedron, one deck alumina octahedral, outward appearance is greyish white, Steel Gray powder, there is oily luster, odorless, tasteless.Density 1.6g/cm3 left and right, three grades of rubbing hardness.When moist, aobvious viscosity, has plasticity-, and dry post shrinkage is few, does not produce be full of cracks.Specific surface area is large, and every gram of soil can reach 350m
2above, water-absorbent is strong, generally can reach more than 150%, and chemical property is very stable.
Summary of the invention
The object of the invention is to provide the preparation method of the modified attapulgite clay that a kind of modified effect is good.
The solution of the present invention is as follows: a kind of preparation method of modified attapulgite clay, it is characterized in that first attapulgite clay raw ore being dropped in fragmentation broken, then with twin rollers, the attapulgite clay of fragmentation is pushed, obtain the thick sheet attapulgite clay of 2-3mm, drop in mixing pan, add aluminum oxide, aluminium hydroxide to mix, then be put in twin rollers extruding, then pull an oar, filter, dewater, be dried, pulverize, can obtain modified attapulgite clay.
Described pair roller number of times is 6 times.
Beneficial effect of the present invention: working method is simple, production cost is low; The modified effect of product is good.
