Problems solved by technology

[0004] However, the primary amine compound used in the early spraying of polyurea reacts with the isocyanate group too quickly (gel time is 5-10s), requiring special spraying equipment for construction, which not only limits the application places, but also requires high equipment prices, which require careful attention. maintain
Excessive reaction speed also leads to insufficient wetting of polyurea materials to the substrate, poor adhesion, insufficient leveling time, and orange peel defects on the surface, etc.
In addition, due to the introduction of hydrophilic groups in the preparation process of polyaspartate polyurea, the coating is easy to absorb moisture, poor in hydrophobicity, poor in thermal performance and mechanical performance, etc.

Description

technical field [0001] The invention relates to the technical field of 5G base station cabinet materials, in particular to a 5G base station cabinet with thermal insulation, anti-corrosion and anti-rust functions. Background technique [0002] 5G base station is the core equipment of 5G network, which provides wireless coverage and realizes wireless signal transmission between wired communication network and wireless terminal. As of the end of March 2020, 198,000 5G base stations have been built nationwide, and more than 500,000 5G base stations are expected to be built throughout the year. The normal operation of a 5G base station is inseparable from the escort of a high-quality and high-performance base station cabinet. A qualified high-performance base station cabinet needs to have the characteristics of heat insulation, anti-corrosion and anti-rust, high temperature resistance, and good weather resistance. [0003] Polyaspartic acid ester resin is a kind of aliphatic se...
