Description
Technical field
The present invention relates to a kind of shell powder, preparation method thereof, especially a kind of modification conch meal system with good dispersion
Preparation Method.
Background technique
China's shellfish yield of about 12,000,000 tons/year, account for Gross World Product close to 60%, but for a long time China for
The utilization overwhelming majority of shellfish is confined to edible part, and the shell part for accounting for 60% or more shellfish quality but seldom processes benefit
With, produce a large amount of waste shells, be not used effectively not only, but also be largely deposited in as solid waste seabeach or its
His soot, waste of resource pollute environment.It is this based on calcium carbonate and containing a small amount of organic matter how shell is efficiently used
Biological material is people's hot spot of interest all the time.Although conch meal is used as animal feeding-stuff additive and calcium supplement already
It uses, but its actual amount is relatively fewer, can not effectively consume a large amount of shellfish deposits generated every year.In recent years, by shell
Powder causes people's broad interest for Material Field.In the related art, shell powder is had become applied to anticorrosive paint
For current important industry.
In order to prepare High Performance Corrosion Protective Coatings, related personnel using be added in anticorrosive paint system suitable pigments and fillers,
The modes such as auxiliary agent improve the performance of coating, and wherein to be that current anticorrosive paint field is the most commonly used fill out for calcium carbonate and glass flake
Material, but inorganic carbonate calcium powder body and glass flake all have significant hydrophilic and oleophobic characteristic and highly polar, cause it viscous with resin
Bad, poor compatibility is tied, disperses unevenly, to sprawl difficulty in organic media, so that defect is generated inside film, reduction property
Energy.Shell pearl layer is the canonical biometric mineral material being made of calcium carbonate and large biological molecule compared with above-mentioned material, is one
Kind natural inorganic-organic composite material, while shell itself has typical lamellar structure, by clam shell feature, it is inorganic-
Organic phase regulates and controls and is modified, and development and application are in the bioactivity carbonic acid calcium of coating, and added value is high, and demand is big, and application prospect is wide
It is wealthy, compared with traditional inorganic carbonate calcium and glass flake filler, there is direct application prospect in corrosion and protection field.Cause
This waste shell for generating the related industries such as aquaculture passes through modification application Yu Haiyang anticorrosive paint industry and domestic and international institute

It is 5~40%.Low temperature in step (3) is less than or equal to 60 DEG C.
As shown in Figures 1 to 8, lower heat drying temperature can be effectively retained organic group in shell powder, protect
Demonstrate,prove the activity of powder；The reacting dose of inorganic phase in conch meal body can be quantitatively controlled by control inorganic acid dosage；Pass through acid etching
It can be applied to the high activity Paris white of the oleaginous systems such as coating with the modified preparation of inorganic-organic hybrid of the methods of graft
Body.
Fig. 1 shows the influence after the addition of different modifying agent to powder oil absorption；Fig. 2 shows different modifier modifications to 10p-
The influence of the settling volume of zyb powder；The material phase analysis of shell powder after Fig. 3 is shown before modified, before modified after primary chemical
Ingredient is all the mixture of calcite and aragonite, still remains the basis of calcium carbonate powder；Fig. 4 to fig. 6 is before modified
The infrared spectroscopy of shell powder afterwards, it can be seen from the figure that all remaining the 1500cm of carbonate mineral after before modified-1With
876cm-1Characteristic peak；Comparison diagram 4 and Fig. 5 discovery are in 3000cm-1~2000cm-1There is certain platform, shows phosphoric acid
The structure for changing shell powder is added, realizes certain modified effect；And be added it is coupling agent modified after in 2920cm-1With
2840cm-1There is the absorption peak of methyl and methylene, illustrate it is coupling agent modified after be firmly bonded to shell powder surface, rise
Modified effect is arrived.Fig. 7 and Fig. 8 is modified shell powder SEM microscopic appearance figure, and as can be seen from the figure modified powder contains piece
Shape and prism-shaped particle, sheet-like particle partial size are about 10 μm, some are fuzzy for powder surface, corner angle fuzzy, are phosphoric acid,diluted corrosion
The part calcium carbonate for having fallen shell pearl layer surface allows surface to become coarse, at the same it is coupling agent modified after be coated on powder surface
Caused, this is conducive to powder dispersion effect and stability in the oleaginous systems such as coating, resin.
In conclusion in the present invention associated materials and the relevant technologies utilization, enable the preparation method have lot of advantages,
As both can quantitatively removed the calcium carbonate in shell powder as desired, the modified calcium carbonate powder made is protected in required ratio
Stay calcium carbonate and organic active ingredients；The activity that powder can be increased by organic modifiers again, is maintained at good in organic system
Good dispersibility and stability.Therefore, the present invention has substantive distinguishing features outstanding and significant progress.
The above description is only a preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
