In the service life, entreprise cost is also will increase, complicated follow-up work may be with a variety of losses, with regard to the technology of current cable on the market
It is not enough to accomplish good fire-retardant, fire-proof and damp-proof.This also increases security risk.There are also flame retardant cables in the prior art
Research, such as CN105778242A discloses a kind of flame-proof composite cable material, by following raw material component by weight percentage
It constitutes：Low density polyethylene (LDPE) 25~35%, ethylene-vinyl acetate copolymer 10~15%, sodium bicarbonate 30~50%, red phosphorus 5
~10%；Using sodium bicarbonate as main flame retardant, use red phosphorus for retardant synergist；The cable has certain anti-flammability
Can, but for part high temperature specific area, to the flame retardant property of cable, more stringent requirements are proposed.It is asked based on above-mentioned technology
It inscribes, there are a variety of coating for cable-flame retardant in the prior art, but integrate heatproof, fire-retardant, heat-insulated, adhesive force, density etc.
Overall target is also difficult to the rigors of specific area cable.
Invention content
For the defect for overcoming the cable flame retardance of the prior art poor；The invention discloses one kind being used for electric wire
Fire-retardant method, this method can improve the fire retardant insulating heat resistance of cable.
To achieve the above object, the technical solution adopted in the present invention is as follows：
A method of it is fire-retardant for electric wire, it is that coating is sprayed into cable surface；
Specifically, the coating is prepared according to following technique：
Step 1）By attapulgite and lithium bentonite according to 2:1 mass ratio mixing, is then sent to ball mill, being milled to grain size is
500 mesh powders are to get solid substrate；
Step 2）By sodium carboxymethylcellulose, silica white and silicone emulsion according to 1:2:2 are added in blender, and 300rpm is stirred
10min is mixed to get crosslinking agent；The grain size of the sodium carboxymethylcellulose and silica white is 500 mesh；
Step 3）By nanometer aluminium powder, graphene and Conductive mica according to 1:1:3 mass ratio is uniformly mixed so as to obtain mixture, then adds
To accounting in the n-butanol of five times of weight of mixture, then the bisphenol A type epoxy resin with graphene identical weight is added, ultrasonic wavelength-division
30min is dissipated to get antistatic anticorrosive；
Step 4）Add step 1 successively in the reactor）Solid substrate, polysiloxanes, butyl acetate, acrylic acid and go from
Sub- water, 2000rpm stir 5min, then add step 2）Crosslinking agent, 1000rpm stir 3min, stop stirring, be warming up to 50
DEG C, 10min is kept the temperature, is down to room temperature naturally, then adds step 3）Antistatic preservative, 500rpm stir 10min, stop stirring
It mixes, packs to obtain the final product；The step 1）Solid substrate, polysiloxanes, butyl acetate, acrylic acid, deionized water, rapid 2）'s
Crosslinking agent and step 3）Antistatic preservative mass ratio be 10-15:2-3:3-5:12-18:15-22:3-5:4-7.
The advantageous effect that the present invention obtains includes being not limited to the following aspects：
The present invention is used carries out spray treatment to cable surface, improves heat-proof combustion-resistant insulation performance, effect stability, action effective
It is long；Preparation method simple possible of the present invention, best material combination is determined using orthogonal multifactorial experiment, obtained coating property
It is excellent；The gap of preservative has effectively been filled up in the addition of nanometer aluminium powder material of the present invention, improves water resistance and insulating properties
Energy；The present invention uses the raw material of different-grain diameter so that is combined between each raw material finer and close so that the granular-grade of mixed material connects
Nearly closest packing state, intensity can increase, and microstructure can also be improved；Attapulgite and lithium bentonite conduct
Base-material, compatibility is good, has certain fire resisting, corrosion resistance；Attapulgite is that crystalloid is hydrated alumina magnesia silicate, is had
, there is crystal lattice in its structure in unique layer chain structure feature, threadiness or fiber set shape have unique dispersion,
The good colloidal natures such as high temperature resistant, salt resistance alkali and higher adsorption capacity；The present invention is using sodium carboxymethylcellulose, silica white
And suspension prepared by silicone emulsion has fibrous colloform texture as crosslinking agent, it is strong to stick together adsorption capacity, and dispersion is
It is even, so that coating is had good suspension, thixotropy and adsorptivity；Nanometer aluminium powder and Conductive mica form conductive network, a small amount of
Graphene improves antiseptic property with Conductive mica while formation conduction and anti-corrosion network, antistatic.
