Abstract
The invention discloses a conductive paint and a preparation method thereof. The method comprises the following steps: adding acrylic resin, styrene and acetaldehyde according to a certain ratio to a container, adding an appropriate amount of polyethylene wax powder, stirring and mixing evenly for later use; taking a certain amount of glass fiber, cutting the glass fiber into small fiber segments and adding to spare paint, and ultrasonically vibrating for 1-1.5h under the airtight condition at room temperature to obtain the conductive paint. The conductive paint prepared by the method has strong conductivity, good stability, simple process and wide application.
Description
Technical field
The present invention relates to a kind of electro-conductive material, particularly a kind of electroconductive paints and preparation method thereof, belongs to chemical field.
Background technology
Along with increasing sharply of various commercialization and domestic electronic appliances quantity, Electromagnetic Interference (EMI) has become a kind of new social effects of pollution.At present some economically developed countries and relevant international organization have promulgated the regulation of shielding EMI in the world, and in recent years, computer and Computer Communication Networks almost enter each field, and the consequent needs solution electromagnetic radiation from computer problem.Computer Electromagnetic Radiation is leaked in two ways, i.e. leakage and radiation leakage.For the former, various outlet line coated with conductive is painted, can the leakage of counterchecking electromagnetic wave; For the latter, spray machine room inwall by electroconductive paints and computer case is shielded, the radiation leakage of electromagnetism can be avoided.Electroconductive paints is except except the application in antistatic, EMI shielding etc., and the optics that electroconductive paints is excellent and chemical property, make it in a series of high-tech area, as the aspect such as molecular circuit, electron membrane all has wide market outlook.
Electroconductive paints tempo is abroad very fast, enter practical stage, and the research and development of China in electroconductive paints is started late.Within 1984, electroconductive paints research is tackled key problems as key scientific and technological projects by China, and applies at electron trade, coal industry.But because also there is a big difference compared with abroad in the kind of product, performance and industrialization, mainly go back dependence on import.And developing rapidly in recent years along with China's electronic industry, very urgent to the demand of anti-electrostatic, elimination electrostatic product, also requirement electroconductive paints replaces part metals goods to carry out electromagnetic wave shielding, and this research and development being cut to electroconductive paints brings sound social environment.
In general, more high better to the shielding properties of electromagnetic shielding material, but, see through threshold values by the conductor of filled-in composite to learn, the loading level that one-dimensional electric particle is formed needed for conductive effect is often comparatively large, and massfraction generally reaches about 60%-80%, when so huge incorporation, paint class material then as easy as rolling off a log be full of cracks goes bad, and work-ing life is shorter than common paint greatly.Electro-conductive fiber is added in paint, electroconductive paints can be prepared, electro-conductive fiber content is higher, the electric conductivity of electroconductive paints is better, but during the too high levels worked as, electroconductive paints cost is high and the work-ing life of film forming is short, and in order to overcome this problem, the present invention forms a kind of excellent electroconductive paints by the appropriate aluminium-coated glass-fibre of interpolation, rational proportion.Since ensure that electric conduction paint has good conductivity and has again longer work-ing life.
Summary of the invention
The object of this invention is to provide a kind of preparation method of electroconductive paints, the method is carried out as follows:
(1) appropriate acrylic resin, vinylbenzene and acetaldehyde are put in a container successively, and ceaselessly stir;
(2) in above-mentioned solution, add polyethylene wax powder, make it mix, obtain elementary paint mixture;
(3) get appropriate aluminium-coated glass-fibre, it is cut into the segment of fiber of 10-20mm;
(4) add in elementary paint mixture quality for the fiber described in 15-40% break;
(5), under normal temperature air tight condition, sonic oscillation 1-2h, can obtain electroconductive paints.
Preferentially, the contained mass ratio of described elementary paint component of mixture is: acrylic resin (40-50%), vinylbenzene (20-40%), acetaldehyde (20-40%) and polyethylene wax powder (5-10%).
Preferentially, described aluminium-coated glass-fibre inner core is the glass fibre of diameter 15-17 micron.
Preferentially, described aluminium-coated glass-fibre coat-thickness is 1.0-1.5 micron.
