Dimension, modified attapulgite clay, filler and age resistor, after being well mixed, by reactor temperature programming to 130 ~ 140 DEG C, are protected
Temperature 5 ~ 10min of reaction, cooling obtains mixture a4；
（5）Mixture a4 is put into mold cavity carry out it is hot-forming, wherein hot pressing temperature be 140 ~ 150 DEG C, hot pressing pressure
Power is 250 ~ 260MPa, and the hot-press solidifying time is 20 ~ 30min, after cooling, produces the high and low voltage electric distribution device shell.
7. noise abatement according to claim 6, the preparation method of anticorrosive high and low voltage electric distribution device shell, it is characterised in that institute
State step（3）The middle amount that water is added into ball mill causes the water content of mixture to be 10 ~ 15%.
8. noise abatement according to claim 6, the preparation method of anticorrosive high and low voltage electric distribution device shell, it is characterised in that institute
State step（4）The method of Program heating is at the uniform velocity to be warming up to 130 ~ 140 DEG C with 10 DEG C/min speed.
9. noise abatement according to claim 6, the preparation method of anticorrosive high and low voltage electric distribution device shell, it is characterised in that institute
State step（4）The preparation method of middle modified attapulgite clay is：
Take natural attapulgite clay to be crushed and cross 200 mesh sieves, add water, stirring forms mud in suspension, takes upper suspension
5 ~ 10min of centrifugal treating in 3000 ~ 3500 turns/min centrifuge, vacuum filtration, obtains filter cake；
Filter cake is placed in beaker, 2mol/L watery hydrochloric acid is added, wherein the volume of hydrochloric acid and Concave-convex clay rod quality it
Than for 1mL：5 ~ 10g, is placed under Ultrasonic Conditions after 10 ~ 20min of ultrasound, standing and is filtered by vacuum, and is cleaned with distilled water, must filter
Cake；
Filter cake is dried, is subsequently placed in Muffle furnace and is warming up to 800 DEG C with 20 DEG C/min speed program, 3 ~ 4h of constant temperature calcining,
Cooling, crushes and crosses 200 mesh sieves, produce modified attapulgite clay.
