The present invention uses above-mentioned technical scheme can reach to provide the benefit that: the present invention is molten with silicon
Glue is matrix, adds various inserts and prepares gained.The resistance to water of Ludox, heat resistance are bright
Showing and be better than organic coating, film is fine and close and harder, does not produce electrostatic, and in air, various dust are difficult
Adhere to, there is the strongest contamination resistance.Acetylene carbon black is super-normal structure black, is easily formed space
Network channel, beneficially polymer are formed chain type conductive structure, and nano titanium oxide has
High electrical conductivity, the electric charge making surface gather spreads rapidly along surface, it is to avoid internal field
Too high and shelf depreciation occurs, meanwhile, nano titanium oxide also has the effect absorbing ultraviolet light,
And dissipate by the way of heat, therefore can play a protective role.Aluminum phosphate chromium can as adhesive
Plasticity is good, Heat stability is good, along with the rising intensity of temperature strengthens the most accordingly, and its contained three
Valency chromium will not be transformed into toxicity Cr VI, and safety is high.SHP-50 polysiloxanes powder hydrophobic,
After solidification good to water repellency, there is stronger hydrophobicity and durability.SER-AD FA179
The corrosion inhibitor that can be used as water soluble paint prevents from dodging the formation of erosion.Colophonium belongs to hydrophobicity
Material, but viscosity is very big has mobility, corrosion-resistant and have toughness.Guar gum WP-05
Uniformly dispersed for rheology modifier, beneficially coating, has resistance to water and has significantly
Price advantage.
In preparation process, first epoxy resin and polyester resin are mixed, at a certain temperature in
In mill mixing, make both dispersed by the levelability of guar gum, may advantageously facilitate poly-
In ester, the hydroxyl in carboxyl and epoxy resin, epoxy reaction, draw have both combination properties
Epoxy polyester, availability is higher.And Colophonium and epoxy resin also are able to reaction and generate epoxy drip
Green grass or young crops, it is strong that this Colophonium compares plain asphalt corrosion resistance, and has certain elasticity.Acetylene charcoal
Black and nano titanium oxide addition by several times is mixed with and the most fully reacts, the polymer space of formation
Structure is more stable, and the antioxidant being subsequently added makes living radical before macromolecular chain aoxidizes
Just lose activity, thus can effectively stop polymer oxidation, degraded, improve polymeric material
Inverter fed motor ability.
In summary, electric armour clamp coating even compact of the present invention, have excellent corrosion-resistant
Property and corona resistance, can be effectively ensured the practicality of electric armour clamp, be obviously improved electric armour clamp
Service life, and waterproof, antifouling capacity is strong, has certain elasticity, can be used for vibration-absorptive material
Protection.
