Material for electric meter box shells and preparation method thereof

Abstract

The invention discloses a material for electric meter box shells and a preparation method thereof, belonging to the technical field of materials and solving the problem that existing materials for meter boxes have poorer comprehensive properties. The material comprises the following raw materials in parts by weight: 120-140 parts of polycarbonate, 70-80 parts of glass fibers, 30-40 parts of epoxy silicone oil, 10-20 parts of polyethylene, 10-30 parts of glycidyl methacrylate, 1-3 parts of potassium perfluorobutanesulfonate, 10-20 parts of styrene, 1-3 parts of antioxidant 168, 2-4 parts of antioxidant 1010, 1-3 parts of light stabilizer 770, 1-3 parts of ultraviolet light absorber, 2-10 parts of oxidized polyethylene wax and 0.2-0.6 part of pentaerythritol stearate. The preparation method comprises the following steps: weighing the raw materials according to the parts by weight, adding the raw materials to a high-speed mixer to be mixed, then granulating the mixture with a twin-screw extruder, and drying and then injection-molding the obtained granules, thus preparing the material. The material can be widely used for the electric meter box shells.

Description

technical field [0001] The invention relates to a meter box shell material and a preparation method thereof, belonging to the technical field of materials. Background technique [0002] The electric meter box shell is the protection device of the electric meter. The materials used for the electric meter box shell are mostly bakelite, plastic, iron shell, and stainless steel at first. , Stainless steel materials replaced; iron case, stainless steel watch box, because of its poor insulation performance, easy to rust, poor waterproof sealing ability, its usage is getting smaller and smaller. The initial application effect of thermoplastic watch box is good, but the density and anti-ultraviolet performance of the product are poor, it is easy to age, the fire resistance is poor, the bearing capacity is not enough, and there is a certain softening and creep under high temperature conditions, so its use is subject to certain restrictions. limit.
