Abstract
Modified drift-sand, described modified drift-sand is to be prepared with modified cyclodextrin/vinyl silicane coupling agent mixture modification by drift-sand, described drift-sand is through strong acid treatment, described modified cyclodextrin is 1:0.1 10 with the mass ratio of vinyl silicane coupling agent, dissolubility under described modified cyclodextrin 25 degrees Celsius is more than 5g/100g water, described modified cyclodextrin is the cyclodextrin that in a cyclodextrin molecular, 13 hydroxyls are replaced by benzene alkyl acid, and modified drift-sand performance in terms of polyurethane coating that the present invention obtains is the most outstanding.
Description
Technical field
The present invention relates to modified drift-sand, the invention still further relates to the preparation method of drift-sand filler, the invention still further relates to contain
The polyurethane coating of this modification drift-sand.In particular it relates to international Patent classificating number C01B33/00.
Background technology
Drift-sand is by wind, the sand bed of accumulation.It is more common in desert, Gobi desert.Its particle diameter be mainly distributed on 0.074～
Between 0.250.
China is the country in desert more than, and dust storm area is about 173.11 ten thousand square kilometres, accounts for national area
18.03%, it is mainly distributed on Xinjiang (58.9%), the Inner Mongol (29.9%), Qinghai (5.3%), Gansu (2.7%), Shaanxi
(1.5%), the provinces and regions such as Ningxia (0.6%).
According to authority's document announcement, NORTHWEST CHINA area just pushes away to desertification with the surprising speed of annual 2000 square kilometres
Entering, the economic loss caused to China every year reaches more than 500 hundred million yuan, more allows people's worry, ecological environment here receive sternly
The destruction of weight.
Desert wind sand is acknowledged as useless husky, calamity sand, misfortune sand, and few people carry out research and utilization to it.Over the years, the mankind
Desert Control drift-sand is mainly in surface layer of desert planting trees and grass, but due to the extreme climate environment in desert, the survival of tree planting
Rate is low, and sand control effect is bad.Drift-sand useful industrially is possible not only to desert wind sand, moreover it is possible to bring good economic benefits.
But due to the characteristic of drift-sand itself, drift-sand is difficult to substitute existing filler, and the modification of drift-sand is ability
The big technical barrier of the one of territory.
Summary of the invention
In order to solve above-mentioned technical barrier, the invention provides a kind of modified drift-sand.
Modified drift-sand, described modified drift-sand is to be mixed with modified cyclodextrin/vinyl silicane coupling agent by drift-sand
Thing modification prepares, and described drift-sand is through the quality of strong acid treatment, described modified cyclodextrin and vinyl silicane coupling agent
Ratio is 1:0.1-10, and the dissolubility under described modified cyclodextrin 25 degrees Celsius is more than 5g/100g water, and described modified cyclodextrin is one
The cyclodextrin that in individual cyclodextrin molecular, 1-3 hydroxyl is replaced by X, the structure of described X is as follows:
Described R be carbon number be divalent straight or the alkyl of side chain of 1-5.
The 3%-8% that consumption is drift-sand quality of described modified cyclodextrin/vinyl silicane coupling agent mixture.
The particle diameter of described drift-sand is 70-150 micron..
The particle diameter of described drift-sand is 70-150 micron.
The preparation method of modified drift-sand, comprises the following steps:
-drift-sand is screened, remove the drift-sand particle more than 150 microns, obtain selected drift-sand；
-selected drift-sand is contacted 0.1-2 hour with at strong acid solution, described strong acid or strong base solution volume are drift-sand
1-5 times of volume.
-be dried, obtain dry wind sand；
-by modified cyclodextrin with vinyl silicane coupling agent in a solvent under 50-150 degree Celsius fully dispersed, obtain
Dispersion soln；
-dry selected drift-sand is sufficiently mixed with dispersion soln, react 0.2-2 hour under 50-150 degree Celsius；
-be dried, obtain modified drift-sand；
Described modified cyclodextrin is 1:0.1-10 with the mass ratio of vinyl silicane coupling agent, and described modified cyclodextrin 25 is taken the photograph
Dissolubility under family name's degree is more than 5g/100g water, and described modified cyclodextrin is that in a cyclodextrin molecular, 1-3 hydroxyl is replaced by X
Cyclodextrin, the structure of described X is as follows:
Described R be carbon number be divalent straight or the alkyl of side chain of 1-5.
Described solvent is alcohols solvent and/or ketones solvent.
The particle diameter of described drift-sand is 70-150 micron.
The 3%-8% that consumption is drift-sand quality of described modified cyclodextrin/vinyl silicane coupling agent mixture.
Polyurethane coating, including aforesaid modified drift-sand.
The method that the present invention hereinafter be will be further described.In below scheme, except as otherwise noted, respectively define
As defined above.
Detailed description of the invention
All publications mentioned in this article, patent application, patent and other list of references, without contrary explanation, all
Entire contents is quoted clearly addition herein, as they are fully disclosed in this article.
Unless otherwise defined, all technology used herein and scientific terminology have skill common with art of the present invention
The identical implication that art personnel are generally understood that.When there is contradiction, it is as the criterion with the definition in this specification.
Term as used herein " by ... preparation " and " comprising " synonym.Term used herein " comprises ", " including ",
" have ", " containing " or its other deformation any, it is intended that cover the including of non-exclusionism.Such as, the combination of listed elements is comprised
Thing, step, method, goods or device are not necessarily solely those key elements, but can include other not expressly listed key element or
The key element that this kind of compositions, step, method, goods or device are intrinsic.
Conjunction " Consists of " gets rid of any key element, step or component do not pointed out.If in claim, this
Phrase will make claim be closed so that it is does not comprise the material in addition to the material that those describe, but relative often
Except rule impurity.When being rather than immediately following during phrase " Consists of " occurs in the clause of claim main body after theme,

Drift-sand
Drift-sand of the present invention refers to by wind, the sand bed of accumulation.It is mainly composed of quartz, accounts for gross mass
73%, remaining is plagioclase and orthoclase, also contains a small amount of illite and hornblend.Its density is between 1.47-1.70.Many
See desert, Gobi desert.Its particle diameter is mainly distributed between 0.074～0.250.
Drift-sand can obtain from the desert, northwest of China or Gobi Region, desert or Gobi Region the drift-sand obtained

Cyclodextrin
Cyclodextrin (Cyclodextrin is called for short CD) is that amylose is at the cyclodextrin glucose base produced by bacillus cereus
The general name of a series of cyclic oligosaccharides generated under transferring enzyme effect, usually contains 6～12 D-glucopyranose units.Wherein
Study more and have important practical usage be the molecule containing 6,7,8 glucose units, be called alpha-,
Beta-and gama-cyclodextrin.According to X-line crystal diffraction, infrared spectrum and the result of spectral analysis of the nuclear magnetic resonance, determine composition
Each D of cyclodextrin molecular (+)-Glucopyranose. is chair conformation.Each glucose unit is all combined into Isosorbide-5-Nitrae-glycosidic bond
Ring.Can not rotate freely owing to connecting the glycosidic bond of glucose unit, the cylindric molecule of cyclodextrin but taper slightly
Annulus.
Preferably coordinate with coupling agent to obtain, preferably there is the cyclodextrin of 7-9 D-glucopyranose units, pass through
Experiment finds, selects the cyclodextrin of 7-9 D-glucopyranose units more effectively to coordinate with coupling agent, it is thus achieved that more preferably
Modified drift-sand.Possible reason is: less than 6 D-glucopyranose units, then coupling agent is difficult to be covered by cyclodextrin
Intramolecular, and more than 9 cyclodextrin, then coupling agent is difficult to be covered by cyclodextrin molecular.Thus cannot be realized the two at table
The synergism that face is modified.
