Abstract
The invention belongs to the field of power materials and in particular discloses anticorrosive paint for power cables. The paint is prepared from crylic acid, N-methyl pyrrolidone, laurinol polyoxyethylene ether, silicone emulsion, phthalic acid ester, borax, sodium silicate, white graphite, tripolyphosphoric acid, nanosize silica powder and nano titanium dioxide. The paint is capable of effectively preventing acid-base salts from corroding power cables and is relatively good in high-temperature flame retardancy and mechanical property.
Description
Technical field
The invention belongs to electric power Material Field, relate to a kind of anticorrosive coating for power cable.
Background technology
In power supply system, power cable is important transmitting line, and its conductor by one or more mutually insulated and outsourcing insulating protective layer are made, by electric power or information from a wire that is transferred to another place.Power cable is under outdoor environment, especially under damp and hot weather condition or the more serious region of acid-alkali salt effect, aging, burn into disrepair phenomenon very easily occurs, easily cause transmission line malfunction, bring greater impact to the normal production of people and life, also cause larger loss to power department.Power cable anticorrosive coating generally adds various sanitass, softening agent etc. by tertiary acrylic emulsion water-based material and forms; when being corroded condition, paint coatings can generate the spongy foam thermofin of even compact; can effectively suppress corrosion, electric wire, cable are played a protective role.
Prior art has also occurred compared with the coating of polymorphic type and component; cable has been played to certain provide protection; but there is certain defect in it: anticorrosion matrix processing requirements is high; film is blocked up easy to crack; when film curing, be subject to temperature, humidity effect larger, set time is long, and mostly exists weathering resistance poor; the shortcoming that cohesive force is not strong, therefore antiseptic property is generally undesirable.Prior art needs the preferably power cable anticorrosive coatings of parameter such as a kind of antiseptic property and heat-resistant fireproof performance.
Summary of the invention
Easily be corroded in order to overcome power cable material in prior art, flame retardant resistance and water-repellancy are poor, and work-ing life is short, easily occurs the defects such as potential safety hazard, the invention provides a kind of anticorrosive coating for power cable.
For achieving the above object, the technical solution adopted in the present invention is as follows:
For an anticorrosive coating for power cable, it is prepared as follows and forms:
Step 1) prepare material A: in reactor, add successively vinylformic acid, N-Methyl pyrrolidone, ethoxylated dodecyl alcohol, silicone emulsion and phthalic ester, 1000 turn/min stir 5 minutes, obtain material A; Wherein, the weight ratio of vinylformic acid, N-Methyl pyrrolidone, ethoxylated dodecyl alcohol, silicone emulsion and phthalic ester is 10: 6: 5: 3: 1;
Step 2) prepare material B: borax, white graphite and aluminium triphosphate are delivered to ball mill, and being milled to particle diameter is 500 object powder, then powder is mixed with sodium silicate, is material B; Wherein, the weight ratio of borax, sodium silicate, white graphite and aluminium triphosphate is 3: 2: 1: 1;
Step 3) prepare material C: nano-silicon rubber powder and nano titanium oxide are mixed according to the weight ratio of 1: 1, be material C;
Step 4) prepare coating: material A, material B and material C are mixed according to the weight ratio of 22-25: 3-5: 1-2, put in high speed dispersor and stir, then the hygrothermal environment that to be placed in temperature and to be 60 DEG C, relative humidity be 80% 12 hours, finally be cooled to room temperature, pack and get final product.
Preferably, the modulus n of sodium silicate is 2.9; The particle diameter of nano-silicon rubber powder or nano titanium oxide is 10-100nm.
Use-pattern: power cable is soaked in to 10-15 minute in coating, takes out and dry.
The present invention obtain beneficial effect mainly comprise following some:
Anticorrosive coating of the present invention adopts plurality of raw materials compatibility, adopts nano raw material, by reasonable compatibility, has greatly improved the property indices of protective system; The present invention, by adding a certain amount of nano material, together with its special molecular structure can closely be fitted to each raw material, and has filled up the space between each raw material, makes coating top layer smooth; Coating of the present invention possesses good anti-acid-alkali salt and the character such as damp and hot, in the work-ing life of having improved power cable, has reduced potential safety hazard; Coating preparation technology of the present invention is easy, and using method is simple.
