Abstract

The invention discloses a modified polyformaldehyde material used for a communication base station. The modified polyformaldehyde material used for the communication base station is prepared from thefollowing components in parts by weight: 100 to 130 parts of polyformaldehyde, 10 to 20 parts of polyethylene, 5 to 10 parts of conductive carbon black, 5 to 10 parts of metal powder, 0.5 to 5 parts of a liquid dispersant, 0.2 to 0.8 part of a heat stabilizer and 0.2 to 0.5 part of an antioxidant. The modified polyformaldehyde material used for the communication base station is applicable to the special environments with the requirements of weather resistance, long-lasting lubricating, electromagnetic shielding and the like, such as the communication base station.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified polyoxymethylene material used for communication base stations. Background technique [0002] Polyoxymethylene (POM) has good lubricity and wear resistance, but its disadvantages are that the lubricity decreases when it is softened at high temperature or long-term use, and its weather resistance is poor. [0003] Due to the special requirements of its work, communication equipment has the characteristics of good weather resistance, stable wear resistance, and less electromagnetic shielding interference. The development of 5G technology and the amplification of power require the internal structure to have better weather resistance and stability. At the same time, in order to reduce interference, the requirements for electromagnetic shielding are gradually increasing. [0004] The existing imported materials include partial electromagnetic shielding POM, carbo...
