Problems solved by technology

The traditional sealing agent is polyurethane foam, but polyurethane foam has poor fire resistance, is corrosive to cables, is easy to crack, and has poor moisture-proof, sealing and anti-condensation effects. It is blocked, and at the same time, its secondary construction is difficult and the construction cost is high. Basically, the blocked parts cannot be used again

Abstract

The invention discloses a fireproof and anti-condensation material, which is mainly prepared from the following raw materials: vinyl silicone oil, hydrogen-containing silicone oil, platinum complex, anti-condensation hydrophobic filler, flame-retardant filler, flux and leveling agent . The invention also discloses its preparation method: take vinyl silicone oil, add anti-condensation hydrophobic filler, flux, flame retardant filler, leveling agent and anti-tracking additive, disperse and mix uniformly to prepare the base material; take part of the base material, add platinum complex, stir evenly, and make A component; take the remaining base material, add it into hydrogen-containing silicone oil, stir evenly, make B component; among them, the base in A component and B component The material mass ratio is 0.5~1:1. The fire-proof and anti-condensation polymer material of the present invention has a micro-nano rough structure and good hydrophobicity. After testing, the water contact angle on the coating surface is 158-160°, and the rolling angle is 3-6°, effectively preventing the surface Forming condensation, it also has good anti-fouling and self-cleaning effects.

Description

technical field [0001] The invention belongs to the technical field of anti-condensation, and in particular relates to a fireproof and anti-condensation material and a preparation method thereof. Background technique [0002] With the development of society and economy, the demand for reliability of power supply by resident users and enterprises and institutions in the central area of ​​the city is getting higher and higher. The power distribution system is the link in the power system that directly faces users, and has the most significant impact on the reliability of power supply for users. , therefore, the distribution network has become a key link that restricts the improvement of power supply reliability. With the increasing application of ring cages, ring cages have become an important part of the distribution network, and their application range is becoming wider and wider. [0003] Anti-condensation control is an important part of the safety maintenance of the ring ...
