Problems solved by technology

Especially in the old community, more attention should be paid to it. With the gradual increase of high-power electrical appliances, the capacity of the initial meter box cannot bear it, which will lead to heating of household circuits and equipment.
Oxidation, poor contact, or even looseness will also occur at the line joints of the meter box, which will aggravate the heating and ignition of the contact points. At this time, a fire is very likely to break out

Abstract

The invention discloses a preparation method of an insulating and flame-retardant electric meter box shell material. The invention belongs to the technical field of polymer materials. The preparationmethod of the insulating and flame-retardant electric meter box shell material has a wide range of raw materials and a simple preparation method. Through the blending modification and filling modification of dicyclopentadiene and vinyl ester resin, flame retardance and strength of the materials are improved, the materials have good electrical performance, reactive polymerization with an extruder is adopted, then centrifugal casting and compression moulding forming are carried out, preparation efficiency is high, the requirement of the equipment cost is low, the prepared insulating and flame-retardant electric meter box shell material further has outstanding impact resistance, flexibility and heat resistance, and use safety of the shell material is higher.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of an insulating flame-retardant electric meter box shell material. Background technique [0002] In the last century, in the past, the watt-hour meter of each house was often mounted on a wooden board or concealed in a wooden box. As the housing was developed towards practicality, comfort and beauty, especially the development of commercial housing, it was directly powered by the Electric Power Bureau and As a result, household boxes are becoming more and more standardized. Most of the boxes currently used are finished boxes, which are divided into two types of iron boxes or plastic boxes for surface or concealed installation, including inner panels and support panels. [0003] The shell of the meter box is generally made of plastic-sprayed steel plate, once leakage occurs. It will make the person who touches the meter feel "numb and electric", wh...
