Abstract
The invention discloses a PRTV (permanent room temperature vulcanized) long-lasting anti-pollution flashover coating. The PRTV long-lasting anti-pollution flashover coating comprises the following components in parts by weight: 40-55 parts of dihydroxyl polydimethylsiloxane, 20-30 parts of silicon-containing modified fluroresin, 4-6 parts of nano-silicon dioxide, 4-7 parts of cross-linking agent, 0.6-0.9 part of catalyst, 25-30 parts of aluminum hydroxide, 40-60 parts of diluent and 2-4 parts of carbon black. The PRTV long-lasting anti-pollution flashover coating disclosed by the invention has higher hydrophobicity, the hydrophobic angle of the coating is larger than 100 degrees, the mutually matched raw materials, namely the dihydroxyl polydimethylsiloxane and the silicon-containing modified fluroresin are adopted, and the filling agent, namely the carbon black is added, so that the corrosion resistance of the coating can be greatly improved; and the PRTV long-lasting anti-pollution flashover coating further has the advantages of excellent resistance to chemical product corrosion and electrochemical corrosion, resistance to corrosion of acids, bases, salts and most of organic matters, and capability of being suitable for a variety of adverse weather.
Description
Technical field
The invention discloses a kind of antifouling flush paint, specifically a kind of PRTV long-acting and anti-fouling flashing coating with high hydrophobic and erosion resistance.
Background technology
Under abominable meteorological conditions, flashover can occur along the insulator surface of humidity, cause the power system pollution flashover accident.Pollution flashover is threatening the safe and stable operation of power system, and the lighter affects local power, and severe one can impact electrical network, even makes whole electrical network produce cracking.
The natural contamination phenomenon on power system outdoor equipment electroceramics surface is that inevitably along with China's expanding economy, each ground contamination is on the increase, and the close value scope of salt increases year by year.Otherwise porcelain insulating configuration is generally on the low side, and circuit increases year by year, and anti-pollution flashover professional is on the low side, considers the factors such as weather, bird pest of voltage operation and conversion uneasiness again, and the pollution flashover possibility is increasing.
Yet reality is that the technology of anti-pollution flashover does not always catch up with the problem that faces, and maximum problem is the defective of antifouling flush paint: poor adhesive force, can not long-actingly play the function of preventing pollution flashover, and intensity is low, and wear resistance is relatively poor.
Wherein, sixty-four dollar question is the function that can not play longer anti-pollution flashover, itself is along with circuit increases year by year, the speed that anti-pollution flashover professional increases does not just catch up with above-mentioned growth, if coating can not play the function of anti-pollution flashover longer, further bring operating pressure will for anti-pollution flashover professional, the cost of anti-pollution flashover also will strengthen.
Development through celebrating the Spring Festival, antifouling flush paint have certain development, although existing various antifouling flush paint has certain effect for anti-pollution flashover, it can not adapt to multiple extreme climate environment and corrosive medium environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of antifouling flush paint, and this coating can adapt to multiple extreme climate environment and corrosive medium environment.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of PRTV long-acting and anti-fouling flashing coating with high hydrophobic and erosion resistance is characterized in that comprising the component of following weight part:
Described catalyzer is epoxide modified catalyzer.
The present invention has higher hydrophobic nature, the hydrophobic angle of coating is greater than 100 °, the raw material that adopts dialkyl polydimethylsiloxane and siliceous modified fluorin resin to cooperatively interact, add the weighting agent carbon black, can greatly improve the erosion resistance of coating, therefore it has excellent chemical corrosion and electrochemical corrosion performance, and antiacid, alkali, salt and most organic corrosion can adapt to multiple atrocious weather.
