Description
Technical field
The invention belongs to organic silicon rubber cohesive material technical fields, and in particular to a kind of to be exclusively used in the viscous of substation field
Property material.
Background technique
Safety nameplate, using frequently, can play a warning role field personnel in substation field.Such as
The suspension of blocking that charging equipment is closed in job location " is halted, Keep Clear-High Voltage！" nameplate, on job site or repair apparatus
Suspension " works herein！" nameplate.The nameplate in substation is mostly pure plastics or plastics, soft magnetic materials with magnetic at present
It is made, and with a rope for suspension.Power transformation operation maintenance personnel is made ferrimagnet when arranging safety measure
Bin then can be by the way of absorption, but then can only be viscous using adhesive tape for bin made of nonferromugnetic material
Paste or look for hanging point to hang nameplate.Therefore it is easy to swing or fall in the case where there is wind, influences the use of nameplate, also result in
The waste of manpower and goods and materials.
The present invention is directed to power generation scene feature, and organic silicon rubber is fabricated to cohesive material applied to substation's operation
In live nameplate, problem above has been well solved.The present invention will be based on the micro- sucker bionic of tree frog vola, in conjunction with production work
Make demand, organic silicon rubber (PDMS) is selected to make cohesive material.
Summary of the invention
The purpose of the present invention is to provide a kind of cohesive materials for being exclusively used in substation field.The organosilicon that the present invention uses
Rubber material has insulating properties, high temperature tolerance, high-weatherability, can temperature limit it is wide, and be not easy by ozone and ultraviolet light point
Solution.Simultaneously because nameplate need to be repeated as many times use, therefore organic silicon rubber of the present invention should also have ductility it is good,
The features such as easily peelable.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of cohesive material being exclusively used in substation field, raw material components include: raw-silastic continuously according to parts by weight

~ 12 parts, 3 ~ 5 parts of tin indium oxide, 3 ~ 5 parts of silane coupling agent, 1 ~ 3 part of crosslinking agent.
Wherein conch meal is configured to the ion in absorbent insulation material well with porous fibrous double helix construction
Impurity reduces the concentration big because of the free ion of Leakage Current, and then plays the role of improving electrical insulation capability, and its is porous
Fibrous structure extends the diffusion path of corrosive medium, and crack sensitivity can be dropped by being suitably oriented in silicon rubber；Stearic acid
Addition promote inorganic merging with organic media, improve the ductility of rubber；Tin indium oxide has heat-insulated well
Effect, can be improved the high temperature resistance of material, and it can be used as reinforcing agent, the tear-proof of organic silicon rubber is greatly improved
Intensity, but the disadvantage is that electrically conductive, and the present invention is mixed by stearic acid effect with tin indium oxide by addition conch meal,
Greatly reduce the electric conductivity of rubber.
Remarkable advantage of the invention is:
A kind of cohesive material being exclusively used in substation field of the present invention has insulating properties, high temperature tolerance, high-weatherability,
Ductility is good, can temperature limit it is wide, and be not easy by ozone and ultraviolet photodegradation, and compound obtained organic silicon rubber is viscous
Property is extremely strong, is very suitable for substation field application.
