There is mechanical strength high, the advantage such as lighter in weight, also there is stronger resistance to pollution flashover ability, maintain easily,
Therefore increasingly it is widely applied in power system.
It is generally required to substantial amounts of interpolation hydroxide in the material that composite insulator silicon rubber full skirt is used
Aluminum, plays trace agent as tracking-resistant according to this, and addition can be more than 40%.But, aluminium hydroxide and silicon
The compatibility of rubber is very poor, can cause the mechanical properties decrease of silastic material, causes it easily to occur
Turn white, the phenomenon of efflorescence so that insulator ageing resistace decline, decrease service life.
So, improve the mechanical property of insulator umbrella material, increase the ageing resistance of insulator umbrella,
Can effectively extend the service life of composite insulator.
Chinese patent 200910110891.5 discloses a kind of ageing-resistant composite insulator silicone rubber material
Material and preparation method thereof, this invention inserts aminomethyl phenyl in 110-2 methyl vinyl silicone rubber matrix
Silicones, the introducing of phenyl, it is suppressed that the oxidation of side base, phenyl form steric hindrance on silica chain, make
Main chain relatively difficult degradation, thus improve the heat stability of silicone rubber further；Aluminium hydroxide adds
Z-6173 dispersing aid, and enter ultrasound wave airflow milling, make powder at the high speed and high pressure gas of different directions
Under stream effect, the fresh surface of formation has reactivity, thus improves aluminium hydroxide and silicone rubber
The compatibility, can effectively improve the ageing resistace of silastic material.But, in the method still
Employ substantial amounts of aluminium hydroxide, fundamentally do not improve the mechanical property of silastic material, prolong
The service life of long silicon rubber umbrella skirt.
Summary of the invention
