1300~400cm-1For silicate feature area.Sour modified meerschaum wave number 1020cm-1The vibration band at place is actually by 1207cm-1, 1076cm-1 and 1020cm-13 different spectral bands compositions, it should belong to the flexible vibration of Si-O in Si-O-Si tetrahedral layer
It is dynamic.Absorption peak strength of the sepiolite at this after coupling agent modified weakens, and slightly mobile to lower wave number direction, is indicated above silicon
Alkane molecule can also form covalent bond by Si-O or Si-OH group and graft on sepiolite surface.Wherein acid concentration is 2mol/
When the HCL of L, modification is most obvious, effect is best.It is modified to be easier to sepiolite and epoxy resin, titanium nanometer form stable painting
Layer.
Fig. 3 is the dispersion effect figure that titanium nanometer anticorrosive paint and sepiolite coat titanium nanometer anticorrosive paint；Wherein (a)
For the dispersion effect figure of titanium nanometer anticorrosive paint, it can be seen from the figure that coating has been after titanium nanometer anticorrosive paint one month
It is more through precipitating, it is precipitated completely substantially after 4 months；Scheming (b) is the dispersion effect that sepiolite coats titanium nanometer anticorrosive paint
Fruit figure, as can be seen from the figure the titanium nanometer anticorrosive paint dispersion of sepiolite cladding is still intact after four months, does not precipitate,
The addition for further illustrating modified meerschaum improves the dispersion of titanium nanometer really.
Fig. 4 is the coating result figure that sepiolite coats titanium nanometer anticorrosive paint, and sepiolite cladding titanium nanometer is prevented again in figure
Rotten paint coatings densification is flat and smooth, granularity is small, without excessive particle, illustrates to be formed with resin after sepiolite cladding titanium nanometer
Film good film-forming property reaches expected experiment effect.
Schematically the invention and embodiments thereof are described above, description is not limiting, attached drawing
Shown in also be the invention one of embodiment, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, in the case where not departing from this creation objective, not inventively design and the technology
The similar frame mode of scheme and embodiment, should belong to the protection scope of this patent.
