China is the big country of oyster production and processing, substantial amounts of oyster shell clout is produced per annual meeting, for the place of such material
Reason mostly is to be filled, and not only causes the waste of material, can cause certain harm to environment again, to this present invention selection with
Oyster shell is material composition, and a kind of filler is made and is used in coating, can not only reduce cost, and can environmental protection, realize waste
Recycling.Oyster shell powder is first wherein broken into small particle powder shape, dispersed filler and follow-up processing beneficial to filler, then
Immersion treatment is carried out to oyster shell with acid solution, effectively eliminates the impurity component in oyster shell powder, has been dredged logical in tissue
Road, its adsorption capacity is improved, has then carried out calcination processing, effectively eliminated the combination water of inside, improve specific surface area,
Characterization of adsorption is enhanced, has then carried out modification, is first modified processing with modification liquid A, in the presence of ultrasonic wave, is received
The rice good intercalation of silica is in the ratio surface in the institutional framework of oyster shell powder, further improving oyster shell powder
Product so that how dendritic tentacle structure is presented in oyster shell powder molecule, so as to enhance and coating in combination between Multiple components it is strong
Degree, and then the compactness, intensity and thickness of paint film are improved, the use quality of coating is improved, uses modification liquid B again afterwards
Twice-modified processing is carried out, is wrapped again in the outside of oyster shell powder granule and has been grafted the compositions such as NPE, carried
The surface-active of oyster shell powder has been risen, and then has improved scattered compatible properties of the oyster shell powder in coating.
The present invention has advantages below compared with prior art：
The present invention has carried out special modification to oyster shell, and the filler for pump coating has finally been made, can be good
Lifted coating corrosion resistant, it is wear-resisting, water-fast, resistance to ooze characteristic, protecting effect of the coating for pump is enhanced, so as to effectively extending pump
Service life, there is the good market competitiveness and application value.
