Description
Technical field:
The present invention relates to Yi Meng clay production technical fields, and in particular to a kind of preparation method of hydrophobic Yi Meng clays
Background technology:
Natural Iraq/Mongolia mixed layer clay mineral be aqueous phyllosilicate, is a kind of by montmorillonite lamella and illite lamella
The transiens mineral formed by different proportion along C axles, its basic structural feature are silicon-oxy tetrahedron lamella and aluminum oxide octahedral sheet
Layer infinitely extends on a, b direction of structure cell, and rule repeats, piece and piece composition structural unit layer, in the c-direction without translation week
Phase.Because the lattice position of some silicon atoms is occupied by the iron and aluminium of some low price, thus cause lamella negatively charged, interlayer by
The metal cations such as calcium ion, sodium ion balance the uncharged group such as negative electricity, also a number of hydroxyl.Wherein interlayer sun
Ion can swap with some other groups, and with organic matters such as coupling agents dehydrating condensation can occur for hydroxyl.
Due to the lamellar structure and fire resistance of clay, the barrier property of polymer can be improved by being applied in polymer
And fire resistance.But natural Iraq/Mongolia mixed layer clay mineral good hydrophilic property, water-swellable, it is difficult in organic system compatible.Cause
This in use, must be modified to natural Yi Meng clays, makes its surface switch to hydrophobic, Neng Gouyu by hydrophilic in organic system
Polymer-compatible.
Existing organoclay method is usually to carry out cation exchange, cation exchange using cationic surfactant
Method be generally modified in pure water, can produce a large amount of bubbles, reduce products collection efficiency and simultaneously made troubles to production, and this
Method only slightly reduces the hydrophily of clay minerals, not only not up to hydrophobicity (water contact angle be more than 90 °), and with
Time elapses, and contact angle also occurs that further decline.Therefore the organic clay obtained in general using this method can not be with
Polymer combines well, and its organic compatibility needs further to be improved.

In any of the above-described scheme preferably, drying temperature is 80~110 DEG C.
Beneficial effect:
1 can fully confirm that obtained hydrophobic Yi Meng clays have moderately good hydrophobic effect by Fig. 1 Fig. 2.
The 2 hydrophobic Yi Meng clays being prepared by the method for the present invention have excellent organic compatibility, can be dispersed in poly-
Composite is formed in compound, strengthens the barrier property and fire resistance of composite.
3 preparation methods are simple, avoid caused a large amount of foams, low for equipment requirements and yield in preparation process high.
Brief description of the drawings
Contact angle photo before Yi Meng clay alterations in Fig. 1 present invention;Powder water-swellable in Fig. 1, contact angle are 0 °
Fig. 2 is that contact angle photo, middle water droplet keep the form in photo after Yi Meng clay alterations in the present invention, and contact angle is
108°。
Fig. 3 is infrared spectrogram, wherein 2962cm before and after Yi Meng clay alterations in the present invention-1The absworption peak at place is that-CH is anti-
Symmetrical stretching vibration absworption peak.And-CH is organo-functional group, therefore this functional group is not present on unmodified Yi Meng clays.In addition
3400cm-1Neighbouring peak is the-OH stretching vibration peaks of physical absorption water, and the peak is decreased obviously in modified infrared spectrogram.
