Abstract
The invention discloses a composite nanometer electrostatic screening coating and a process thereof. The preparation process comprises the following steps: taking a certain amount of an organic silicon resin, and adding a zinc stearate dispersing agent; uniformly mixing, slowly dripping acrylic resin emulsion for emulsifying, sequentially adding talcum powder and Fe2O3 powder after emulsification, dispersing and stirring the mixture; and finally adding cellulose acetate, fully mixing, thereby obtaining the composite nanometer electrostatic screening coating.
Description
Technical field
The present invention relates to a kind of composite coating, particularly a kind of composite coating with electrostatic shield effect, belongs to paint field.
Summary of the invention
The application of nano material in coating is generally nano material is added to the nano composite dope made after dispersion in traditional coating, makes the indices of coating all obtain significant raising.Due to the small-size effect of nanoparticle, surface effects, quantum size effect and macro quanta tunnel effect etc. make they magnetic, optical, electrical, responsive etc. in present the characteristic that conventional material do not possess, make it have broad application prospects in the sintering, catalysis, sensing, ceramic toughening etc. of magneticsubstance, electronic material, optical material, high compactedness material.
Nanometer Fe

3there is good weathering resistance, photostabilization, magnetic and to ultraviolet, there is good absorption and shielding effect, can coating be widely used in.This nanoparticle with characteristic of semiconductor at room temperature has the electroconductibility of the oxidation object height than routine, thus can play electrostatic shielding effect.
The preparation method of nano paint can be divided into four kinds: (1) sol-gel method, by the in-situ preparation of nanoparticle in monomer or resin solution; (2) situ aggregation method, refers to that nanoparticle is directly dispersed in monomer, generates nano paint after polymerization; (3) blending method, refers to the composite of nanoparticle and resin solution or emulsion; (4) graft process, enters inorganic nano interlayer by monomer or polymers soln, obtained nano paint.Wherein blending method technique is the simplest, but due to nanoparticle specific surface area and surface tension all very large, easily absorption and reuniting, it is very difficult in the solution it being dispersed into effectively nanometer particle.Under the present invention adds the condition of Zinic stearas dispersion agent in resin, mix the nanometer Fe with semiconductor property
