A bacteriostat and algaecide composite material is arranged on the surface of the insulator; the composite material is prepared from the following raw materials in parts by weight: 6-10 parts of a nano-zinc oxide bacteriostatic agent, 6-10 parts ofa nanometer titania bacteriostatic agent, 3-8 parts of a cuprous chloride mildew preventive, 3-8 parts of cadmium sulfide algaecide, 20-30 parts of polydimethylsiloxane, 5-10 parts of fluorosilicon oil, 5-10 parts of acrylic-2-ethylhexyl acrylate, 10-18 parts of cellulose acetate, 15-30 parts of an ethylene-propylene-diene monomer, 10-15 parts of decabromodiphenyl ether, 5-10 parts of dipentaerythritol hexaacrylate, 3-8 parts of melamine sodium phosphate, 10-25 parts of silicon dioxide, 10-20 parts of aluminum hydroxide powder, 3-5 parts of hydroxyl silicon oil, 3-5 parts of gamma-aminopropyltriethoxysilane, 0.5-3 part of 2,5-dimethyl-2,5-bi(tert-butyl peroxy) hexane, 0-30 parts of toluene, and 0-50 parts of petroleum ether. The composite insulator for preventing microorganism and algae from breeding, disclosed by the invention, has bacteriostat and algaecide effects, and the insulator performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of insulators, and relates to a composite insulator for preventing the growth of microorganisms and algae. Background technique [0002] Composite insulators have the advantages of light weight, high strength, strong pollution flashover resistance, and convenient manufacturing and maintenance. They can reduce the length of insulator strings, reduce the height of towers, save 26% of steel, save 50% of land, and can effectively solve the problem of creeping Insufficient ground distance. It avoids the large power loss of power grid enterprises caused by power outage cleaning and maintenance and the loss of industrial and agricultural power outages. Avoid personal accidents in line maintenance operations. It reduces the large number of maintenance personnel and capital investment required in the maintenance of the line, and reduces the operating cost. It solves the bad conditions such as inconvenient transpor...

AI Technical Summary

Problems solved by technology

These microorganisms and algae reduce the insulation level of the composite insulator on the surface of the insulating umbrella sleeve, reducing its carrying voltage capacity, which is easy to cause power transmission and transformation accidents, and the algae and microorganisms on the surface can also cause corrosion and damage to the composite insulator

[0005] After the growth of microorganisms and algae during the use of composite insulators, regular manual removal or spraying of sterilizing agents is generally adopted, and more seriously, frequent replacement of composite insulators after damage

The most effective way to sterilize bacteria and algae at present is to add elemental silver or silver ion compounds to the material. This method consumes a lot of precious metal silver, and the cost is high, and metal silver is easy to oxidize under light, which leads to a decrease in bacteriostasis. The silver inside the composite insulator cannot participate in the sterilization of the surface to cause waste; what is more unfavorable is that silver is a highly conductive substance, which will greatly reduce its insulation performance in the material
