Embodiment 1

[0016] A multi-meter-in-one collection communication terminal box, which includes a box body, and the box body is prepared according to the following process:

[0017] Step 1) Mix chlorinated butyl rubber, EPDM rubber, methyl vinyl silicone rubber, polycarbonate and glass fiber according to the mass ratio of 80:50:20:10:1 to obtain a mixture, and mix The materials were blended in a single-screw extruder, granulated to obtain the base resin, and then entered into an internal mixer for banburying. The banburying temperature was 70°C and the banburying time was 3 minutes to prepare the main material;

[0018] Step 2) Mix boron nitride, silicon carbide and alumina according to the mass ratio of 2:1:1, put them into a ball mill and ball mill to 200 mesh powder, which is auxiliary material A;

[0019] Step 3) Mix molybdenum disulfide and graphite according to the mass ratio of 2:1 to obtain a mixture, then add it to N-methylpyrrolidone accounting for twice the weight of the mixture,...

Embodiment 3

[0030] The performance test of the casing prepared by the present invention:

[0031] 1. The tensile strength, elongation at break, high temperature resistance, flame retardancy, and insulation performance of the boxes prepared in Example 1 and Example 2 of the present invention are better, and the specific test results can be seen in Table 1:

[0032] Table 1

[0033]

[0034] 2. Corrosion resistance: soak the box body material in 10% dilute hydrochloric acid solution or 8% sodium hydroxide solution or 8% sodium chloride solution for 480 hours, there is no obvious change in the appearance and performance parameters. The box material has good acid, alkali and salt resistance.

Abstract

The invention belongs to the field of power equipment, and discloses a multi-meter integrated acquisition communication terminal box. The multi-meter integrated acquisition communication terminal boxcomprises a box body; the box body is prepared according to a process which comprises the following steps: (1) mixing, extruding and banburying; (2) mixing and performing ball grinding; (3) mixing andperforming cross-linking; (4) calcining; (5) performing injection moulding. Various raw material components of the box body have a good synergistic effect; the box body has high mechanical performance, and has excellent cold and heat stability, corrosion resistance and heat insulating property.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a multi-meter-in-one acquisition communication terminal box. Background technique [0002] The multi-meter-in-one collection and communication terminal box is used to assemble and protect various electrical equipment. The box material requires good insulation performance, corrosion resistance, radiation resistance, and good mechanical properties. At present, flame-retardant ABS is mostly used as the shell material of the box in China. Although flame retardant ABS is cheap, its rigidity is not very good. Chinese invention patent CN101469118A discloses a polymer material for the housing. The polymer material has insufficient mechanical strength and high cost, so it is not widely used. Chinese invention patent CN103740078A is the applicant's prior invention patent. The disclosed shell material has good mechanical strength and flame retardancy, but has a low heat disto...
