Abstract
The invention discloses an anticorrosive coating of an underground cable, belongs to the field of cable corrosion protection, and aims at solving the problem that the underground cable is easily corroded by a complicated service environment in the prior art. The anticorrosive coating of the underground cable comprises the following effective components in parts by weight: 5-20 parts of acrylic resin, 5-20 parts of alkyd resin, 2-8 parts of cerium nitrate, 2-4 parts of a preservative, 2-4 parts of propylene glycol, 3-6 parts of aluminum hydroxide and 2-6 parts of a curing agent. The obtained anticorrosive coating is simple in preparation method and good in anticorrosive effect.
Description
Technical field
The invention belongs to cable corrosion-resistant field, specifically, is related to a kind of buried cable corrosion-inhibiting coating.
Background technology
In transmission line of electricity operation, buried cable is susceptible to corrosion by weather, ambient influnence, to equipment and surrounding environment peace
Hidden danger is brought entirely.Bottom line cable burial is in underground, and environment is more complicated, affects the factor of corrosion more, surface humidity, temperature
Degree, soil constituent etc. directly affect the life-span of buried cable, for this purpose, the present invention provides one kind can slow down buried cable corrosion
The anticorrosive paint of speed.
The content of the invention
To solve the above problems, the present invention provides one kind and can be good at protecting underground cables, slows down the underground of underground cables corrosion
Cable corrosion-inhibiting coating.
Buried cable corrosion-inhibiting coating of the present invention, including the active princlple of following weight portion：Acrylic resin 5-20 parts, alcohol
Acid resin 5-20 parts, cerous nitrate 2-8 parts, preservative 2-4 parts, propane diols 2-4 parts, aluminium hydroxide 3-6 parts, curing agent 2-6
Part.
Preferably, buried cable corrosion-inhibiting coating of the present invention, including the active princlple of following weight portion：Acrylic resin 10
Part, 15 parts of alkyd resin, 6 parts of cerous nitrate, 2 parts of preservative, 22 parts of propane diols, 32 parts of aluminium hydroxide, 2 parts of curing agent.
Preferably, the curing agent is amine curing agent.
Preferably, the curing agent is aromatic polyvalent amine curing agent.
Compared with prior art, the invention has the beneficial effects as follows：First preparation method is simple, by Multicomponent mixing；System
The anticorrosive paint stable performance made, is coated in the appearance of cable, and it is good to form clear transparent, flexibility, and with one
Determine the coating of mechanical strength, the coating has water-fast, corrosion resistant feature.
Specific embodiment
The present invention is further explained with reference to embodiment.
Embodiment 1
A kind of buried cable corrosion-inhibiting coating, including the active princlple of following weight portion：10 parts of acrylic resin, alkyd resin 15
Part, 6 parts of cerous nitrate, 2 parts of preservative, 22 parts of propane diols, 32 parts of aluminium hydroxide, 3 parts of aromatic polyvalent amine curing agent.
Above-mentioned raw materials are well mixed more sticky corrosion-inhibiting coating is obtained.
Embodiment 2
The present embodiment is same as Example 1 in addition to following characteristics：
A kind of buried cable corrosion-inhibiting coating, including the active princlple of following weight portion：16 parts of acrylic resin, alkyd resin 18
Part, 4 parts of cerous nitrate, 2 parts of preservative, 3 parts of propane diols, 3 parts of aluminium hydroxide, 4 parts of aromatic polyvalent amine curing agent.
Using method：The removing surface of cable is clean, and then hot-air seasoning is uniformly applied coating with methods such as spraying, roller coating
The surface of cable is overlayed on, its natural air drying is then treated.
The corrosion-inhibiting coating for being formed to coating below, carries out service check, predominantly detects acidproof, salt water resistance, solvent-proof performance.
Result of the test is as shown in table 1.
The performance test results of the corrosion-inhibiting coating of table 1
