High-strength antistatic weather-resistant flame-retardant shell for electric power meters and preparation method thereof

Abstract

The invention discloses a high-strength antistatic weather-resistant flame-retardant shell for electric power meters. The shell is prepared from the following raw materials in parts by weight: 90-110 parts of polypropylene, 25-35 parts of a polyolefin elastomer, 2-4 parts of graphene, 10-20 parts of glass fibers, 0.5-0.8 part of an antistatic agent, 8-12 parts of a processing aid, 0.8-1.6 parts of a coupling agent, 8-12 parts of hexamethylphosphoramide, 4-8 parts of nano-titania powder, 0.5-1.5 parts of nano-silica and 12-16 parts of a flame-retardant additive. The shell for the electric power meters is safe and environment-friendly, can resist static electricity, wear and aging, has relatively high tensile strength, bending strength and notch impact strength and is relatively long in service life and excellent in comprehensive property; and meanwhile, the raw materials are easily available, and the preparation method is relatively low in material cost and simple and clear in process and has relatively high practical values and good application prospects.

Description

technical field [0001] The invention relates to the technical field of electric equipment protection, in particular to a high-strength, antistatic, weather-resistant, and flame-resistant electrical instrument housing. Background technique [0002] In recent years, with the development of the national economy and the improvement of people's life quality, the use of electric power instruments and equipment has become more and more frequent. The requirements for protective enclosures are also getting higher and higher. [0003] Due to the current technology, due to poor processing technology, there are shortcomings such as low mechanical strength, poor antistatic performance, no flame retardancy, and weak heat conduction and heat dissipation capabilities in actual use. Therefore, it is necessary to improve the formula of the shell material. Make the material achieve a better heat dissipation effect, thereby improving the performance of the electrical equipment and prolonging t...
