Step 2) prepare auxiliary agent: quartz sand, white graphite and lithium bentonite are delivered to ball mill, and being milled to particle diameter is powder more than 500 orders, is auxiliary agent; The weight ratio of quartz sand, white graphite and lithium bentonite is 1:1:1;
Step 3) is prepared nanometer auxiliary material: nano-silicon rubber powder and nano titanium oxide are mixed according to the weight ratio of 1:1, be nanometer auxiliary material;
Step 4) stirs cooling: base-material, auxiliary agent and nanometer auxiliary material are mixed according to the weight ratio of 15-20:2-3:1-2, then 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 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:
Protective system preparation technology of the present invention is easy, and using method is simple, and material combination is reasonable, and industrial cost is low, is applicable to large-scale industrial production; 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 character, in the work-ing life of having improved power cable, has reduced the generation of potential safety hazard.
