Problems solved by technology

At present, the plastic material of the smart meter shell is mainly PC material. PC material has the advantages of excellent aging resistance, corrosion resistance and sufficiently excellent mechanical properties, but the price of this kind of material is very high, which is not suitable for the smart meter industry in my country. The rapid development of the market; the low-end market is flooded with various secondary recycled modified materials of uneven quality. The mechanical and electrical properties of these materials will be rapidly lost during use, so there are quite serious safety hazards

Abstract

The invention discloses a PC / ABS alloy material used for an ammeter housing. The PC / ABS alloy material comprises the following raw materials in parts by weight: 60-80 parts of ABS resin, 15-30 parts of PC resin, 15-30 parts of modified fiber powder, 5-10 parts of glutaraldehyde, 10-15 parts of polyvinyl alcohol, 3-8 parts of alumina, 5-8 parts of a composite fire retardant, 3-8 parts of a lubricant, 10-15 parts of a reinforced filling material, 2-5 parts of a compatilizer, and 3-5 parts of an auxiliary agent; wherein, the modified fiber powder comprises the modified vegetable fiber and modified mineral fiber. The invention also discloses a preparation method of the PC / ABS alloy material used for the ammeter housing. The PC / ABS alloy material has good machinery performance, good flame resistance and good moisture-proof performance, can satisfy practical usage requirement, and increases the safety coefficient of a housing material.

Description

technical field [0001] The invention relates to the technical field of PC / ABS alloy materials, in particular to a PC / ABS alloy material for electric meter housings and a preparation method thereof. Background technique [0002] As my country's per capita electricity consumption continues to increase, coupled with promoting factors such as the comprehensive construction of smart grids and the transformation and upgrading of rural power grids, the demand for plastic materials for smart meter casings is also growing rapidly. The State Grid Corporation of China requires that the shell of the smart meter should be flame-retardant, sealed, dust-proof, moisture-proof, and waterproof, and have a certain strength. It will not deform after tightening the screws. At present, the plastic material of the smart meter shell is mainly PC material. PC material has the advantages of excellent aging resistance, corrosion resistance and sufficiently excellent mechanical properties, but the pric...
