Description
Technical Field
The invention relates to the technical field of protective paint, and particularly relates to protective paint for power equipment and a preparation method thereof.
Background
With the rapid development of modern science and technology and the power industry, power equipment has become an important part in daily work and life, and diversified power services such as industrial power utilization, civil power, telecommunication, data transmission, internet, business, finance, science and technology, medical treatment and the like are provided for people. Our reliance on electricity also becomes increasingly strong. Compared with the prior art, the power equipment has high precision, more and more complete functions and more expensive manufacturing cost, some power equipment is located outdoors and has bad environment, and the outdoor power equipment is in danger of being corroded for a long time and causes very serious consequences after being corroded. Therefore, the safety of the power equipment is a primary problem to ensure the normal operation of the power service. Therefore, it is very important to apply protective paint on electrical equipment.
The existing protective paint generally adopts epoxy baking paint, but the paint is easy to pulverize after a long time, has short service time, and cannot effectively protect power equipment and prevent the power equipment from rusting; and the performance is low.
In the patent document with publication number CN106519966A, a protective paint for electrical equipment is disclosed, which mainly comprises the following components in parts by weight: 30-40 parts of organic silicon glass resin, 15-20 parts of polyurethane resin, 15-30 parts of diphenol propane epoxy resin, 10-20 parts of thermosetting phenolic resin, 12-15 parts of ceramic particles, 2-3 parts of fumed silica and 1-2 parts of polyamide wax. The protective paint for the power equipment has the performances of wear resistance, temperature resistance, weather resistance, corrosion resistance and excellent adhesiveness; however, the present invention is insufficient in heat resistance, corrosion resistance, adhesion ability, and service life, and cannot protect the safety of outdoor electric equipment well.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the protective paint for the electric power equipment and the preparation method thereof, which have the advantages of strong adhesion, rust resistance, high temperature resistance and corrosion resistance, and can effectively protect outdoor electric power equipment.
The invention provides protective paint for power equipment, which comprises the following raw materials in parts by weight:
30-40 parts of fluorocarbon resin, 12-15 parts of amino resin, 20-30 parts of silicon resin, 1-2 parts of bentonite, 3-5 parts of aluminum powder, 5-8 parts of titanium boride, 8-10 parts of aluminum tripolyphosphate, 6-9 parts of nano silicon dioxide, 3-5 parts of nano montmorillonite, 1-2 parts of titanium dioxide, 1-2 parts of defoaming agent, 0.5-0.8 part of flatting agent, 3-4 parts of dispersing agent, 1-3 parts of corrosion inhibitor and 10-20 parts of water.
Preferably, the particle size of the nano silicon dioxide is 30-35nm, and the specific surface is 200-240 m/g; the particle size of the nano montmorillonite is 20-25 nm; the mesh number of the titanium dioxide is 200 meshes.
Preferably, the defoaming agent is a mixture of emulsified silicone oil, polyoxyethylene polyoxypropylene amine ether and polydimethylsiloxane, and the weight ratio of the emulsified silicone oil to the polyoxyethylene polyoxypropylene amine ether to the polydimethylsiloxane is 3:2: 1.
Preferably, the leveling agent is a mixture of polyacrylic acid and carboxymethyl cellulose, and the weight ratio of the polyacrylic acid to the carboxymethyl cellulose is 1: 3.
Preferably, the dispersant is one or a mixture of more than two of triethylhexyl phosphoric acid, sodium dodecyl sulfate, methyl amyl alcohol, cellulose derivatives, polyacrylamide, Guel gum and fatty acid polyglycol ester.
Preferably, the corrosion inhibitor is a mixture of benzotriazole and sulfonated lignin, and the ratio of benzotriazole to sulfonated lignin is 1: 2.
The invention also provides a preparation method of the protective paint for the power equipment, which comprises the following steps:
(1) weighing the raw materials in parts by weight;
(2) adding the raw materials into a stirrer, stirring for 5-10min, standing for 6-8min, and continuously stirring for 15-20min to obtain a mixture;
(3) and adjusting the pH of the mixture to a pH of 7-8.
Wherein,
the stirring speed of the stirrer in the step (2) is 400-500 r/min.
In the step (2), the temperature is controlled to be 50-70 ℃.
