Embodiment
Below from the utilization example the present invention is described in detail.
First example of the present invention has used the anti-corrosion electric wire of the lubricant 4 of following prescription.Grease is that 40 ℃ of following kinematic viscosities are 30～50000mm for containing the main component base oil
2/ s, 100 ℃ of following kinematic viscosities are 20～1000mm
2The aqueous low polymer of/s when this base oil quality is 100 parts relatively, is equipped with that to make the softening dropping point of grease reach reinforcing agent quality more than 220 ℃ be that 5～50 parts, antioxidant quality are 0.01～10 part, the grease 4 that so is deployed into.
The polymer that uses in first example is the aqueous low polymer that the polymerization by isobutene etc. obtains.This polymer has good insulating properties, chemical stability, and is also very stable to the reaction of light and heat, and has outstanding resistance to water, water proofing property, weather reactivity, characteristic such as ageing-resistant.Extremely low because of the impurity of inside and paraffin composition and volatile oil component content again, and had the characteristics of above the ordinary thermal endurance and low flow point concurrently, be used on the anti-corrosion electric wire 1, can improve the thermal endurance and the cold resistance of anti-corrosion electric wire 1.Moreover the viscosity and the adhesive force of this polymer are fine, even can guarantee under the hot conditions, also can effectively stop it to come off from electric wire.
Above-mentioned aqueous low polymer can be chosen use from the commodity of market sale.
This aqueous low polymer; Preferred use viscosity is 40 ℃ of following kinematic viscosity 30～50000mm
2/ s, 100 ℃ of following kinematic viscosity 20～1000mm
2/ s's.
If the kinematic viscosity under each temperature conditions is lower than above-mentioned lower limit, then this polymer is applied on the electric wire and after laying, produces heat through energising, and the evaporation of base oil composition is very fast, probably can reduce the Corrosion Protection of anti-corrosion electric wire 1.And kinematic viscosity is when being higher than above-mentioned higher limit, and the force feed of grease 4 and handling reduction can be compared difficulty when grease 4 is coated to electric wire or inserts electric wire, also be worthless.
The base oil composition of grease 4 generally adopts mineral oil or artificial oil, the artificial oil here be the monomer of appointment through oligomerization and low according to the thing oligomer.
If with above-mentioned aqueous low polymer is Main Ingredients and Appearance, can use the mineral oil (cyclic hydrocar-bons, paraffin class) of common employing, synthetic wet goods and other oils weight less than 50% mixture as the base oil of the grease 4 of first example.Preliminary election, the amount of polymer is at more than 80% of weight; Preferred, the amount of polymer is at more than 95% of weight.
Reinforcing agent, from the thermal endurance of grease 4, the viewpoint of anti-deciduous, the dropping point of use grease 4 reaches the kind more than 220 ℃.Such reinforcing agent has: the mixture more than a kind or 2 kinds in the macromolecule class reinforcing agents such as urea compounds, polytetrafluoroethylene such as metal complex soaps, bentonite (soil takes off in class) mineral-type reinforcing agent, polymerization urea.
Metal complex soaps obtains after other acid metal salts such as the slaine of chain lock aliphatic acid and acetic acid, lactic acid, adipic acid, dial acid are checked.Metal can for example lithium, aluminium, calcium, barium etc. are arranged.
Bentonite is that the quaternary ammonium compound cation enters the intercalation compound that forms in the phyllosilicate structure of clay pit, and organic solvent is had fabulous dispersiveness, through with base oil mixing swelling after, have the stickiness of increasing, thixotropy.
Above-mentioned reinforcing agent all has good thermal endurance and resistance to water, increases the stickiness height simultaneously, can produce the grease 4 with high thixotropic.Thus, can effectively suppress because the thermal degradation when that comes off, switches on and cause behind the stringing makes the anti-corrosion electric wire performance as the advantageous property of anticorrosion with grease 4.
Under the prerequisite that does not hinder effect of the present invention, as required, can be toward 4 li an amount of antioxidant or metal resistance activating agents of adding of grease.In order to improve its acid resistance, also can add calcium carbonate, magnesium carbonate, calcium hydroxide, magnesium hydroxide etc. in right amount and be subjected to, be subjected to other additives such as weather resisting agent such as sour agent, carbon.
Antioxidant, rotten for preventing the grease 4 that high-temperature oxydation occurs, should weigh in base oil matter and add antioxidant matter in 100 parts and weigh in 0.01～10 scope.Can use phenol, amine, Phosphorus etc. as antioxidant, particularly suitable be phenol and amine.
The manufacturing of grease 4: by carrying out according to suitable methods such as the saponification method of material choice, mixing methods.
For example, the production of metal complex soaps as the grease 4 of reinforcing agent, after oils under normal pressure or the pressurization situation in the heating base oil and metal alkali make its saponification, cooling, add various additives, after heating as requested, mix, carrying out homogenization with milling machine handles, filter, after the deaeration, generate grease 4.
Viewpoint from anticorrosive property, grease 4 not only will be inserted electric wire the inside (in the slit between the former line 2,3), being preferably in the electric wire periphery also coats, but, if electric wire is to be used in the so not harsh place of environmental condition, it is also passable then only to carry out filling, and electric wire is single cord or rub with the hands twists very finely multi cord, need only smear to get final product.
The anti-corrosion electric wire of producing like this 1 just can be used as overhead routes such as aerial high-voltage line, overhead ground wire, and the bus in wire jumper and the transformer station etc.
Describe with regard to second example of the present invention below.But, second example and first example are basic identical except that following some that tell about.At this, the common ground explanation that constitutes is omitted, only do with explanation with regard to its difference.
Anti-corrosion electric wire 1 is originally by applying on electric wire or filling grease 4 makes.Generally speaking, grease 4 can bit by bit absorb moisture, and for years on end ground, acidity or the salt corrosive substance that grades has just soaked into grease 4, touches the electric wire surface, the corrosion electric wire.
Particularly, in the grease of the mineral oil that uses in anti-corrosion electric wire, because the village of impurity exists, corrosive substance enters easily, is difficult to the tolerance corrosion under the environmental condition of strictness.
Second example of the present invention lays stress on the base oil seepage of water of grease 4, contains the grease 4 of low water permeability base oil by employing, stops the intrusion of corrosive substance, thereby reaches the purpose of the Corrosion Protection that improves anti-corrosion electric wire 1.
Record seepage of water, must make film like to the test materials in the past, measure the amount of the vapor permeation film of the moisture of liquid condition or gaseous state then.Meaning and method of measurement to its seepage of water of polymer film are determined, but, the such grease of base oil is difficult to it is made the film like test portion, and, because of the characteristics of grease flowability, even make film like, owing to be accompanied by moving of mobile moisture, the measured value of moisture permeability is easy to change, and can not obtain sufficient precision and dependence.
Chemical constitution is very important as the factor of decision polymer.For the consideration of this point, in second example, the polymer that base oil is relative, promptly, the seepage of water when monomer has with the common polymer film forming shape of base oil, the base oil of selecting grease 4 to use.
