(20) etching aluminum steel
At first dispose etching solution, etching solution is that hydrochloric acid, sulfuric acid and pure water mix according to volume ratio.Blending ratio is seen table 2 particularly.
Then pretreated aluminum steel being put into the etching solution for preparing soaks; Take out and put into the pure water ultrasonic cleaning then rapidly; After removing etch processes, remain in coarse aluminum steel surperficial spot and other PM for particulate matter; Thereby obtaining clean surfaceness is the aluminum steel of micro/nano level, preferably obtains the aluminum steel that surfaceness is 50～80nm.Again aluminum steel is placed on 60～70 ℃, dries under preferred 63～68 ℃ temperature.Soak time in etching solution and ultrasonic cleaning time are seen table 2 particularly.
Obtained the aluminum steel of the micro-nano coarse structure of surface cleaning through step (20), this micro-nano coarse structure help anti-icing paint evenly, effectively attached to the surface of aluminum steel, thereby can improve the bonding force of aluminum steel and anti-icing paint.
(30) preparation coating layer
To put into anti-icing paint through shaggy aluminum steel and soak, and take out at room temperature then and place, again at 80～100 ℃; Under preferred 85～95 ℃ temperature; Heated 2～3 hours, and took out then and naturally cool to room temperature, thereby form the coating layer that one deck coats aluminum steel on the surface of aluminum steel.The amount that is coated on the anti-icing paint on aluminum steel surface is 70～100g/m
2, preferred 80～100g/m
2And because anti-icing paint is a kind of transparent solvent, therefore, the aluminum steel that coats anti-icing paint is identical with the aluminum steel appearance that does not coat anti-icing paint.
Make the processing parameter of coating layer on the aluminum steel surface with embodiment 7～12 explanation below and by the parameter of the bonding force of corresponding aluminum steel of this parameter and coating layer.See also table 2, be parameter and the corresponding bonding force performance of embodiment 7～12.In the table 2, the unit of the soak time of aluminum steel in etching solution is second, and the unit of the ultrasonic cleaning time after from etching solution, taking out be minute, in conjunction with unit of force is grade.Present embodiment is the force measurement that combines that carries out aluminum steel and coating layer according to the method for regulation among the GB/T9286 " cross cut test of paint and varnish paint film ".
Table 2 is proportioning (volume parts), etch process parameters and the corresponding bonding force performance of etching solution when making coating layer
To carry out simultaneous test by embodiment 7～12 aluminum steel of making that is coated with anti-icing paint (2# appearance) and the anti-icing ability that does not coat the aluminum steel (1# appearance) of anti-icing paint; Be specially: the external diameter that does not coat the aluminum steel of anti-icing paint is φ 2.6mm, and the diameter of the aluminum steel behind the coating anti-icing paint is φ 2.6mm, and test is carried out in the climate cabinet; The temperature inside the box is-4.5～-6 ℃; The spray water temperature is 0～1 ℃, ejection drop diameter 0.3～0.6mm, and the water spray cycle is: spray 10s; Intermittently 30s places 120min in the climate cabinet.Measure the weight of 1# appearance and 2# appearance, the icing weight of 1# appearance is 124.4g, and the icing weight of 2# appearance is 0.3g only, and hence one can see that, and the anti-icing ability that aluminum steel coats behind the anti-icing paint significantly improves.
The coating layer of making through embodiment 7～12 and the bonding force of aluminum steel are good, difficult drop-off under situation such as collision, bending or vibrations.In addition; Because anti-icing material is that a kind of contact angle is big, the less super hydrophobic material of roll angle; Can suppress water droplet attached to the surface of aluminum steel and the adhesive power that reduces icing after being coated in the aluminum steel surface, freeze thereby can delay water droplet, and then reduce the weight that the aluminum steel surface freezes.
The present invention also provides a kind of anti-ice and snow transmission pressure.See also Fig. 1, be a kind of cross-sectional view of anti-ice and snow transmission pressure.Anti-ice and snow transmission pressure comprises steel core 1 and twists the four layers of aluminum steel layer 2 in the outside around steel core 1; Wherein, Aluminum steel layer near steel core 1 is referred to as the most inboard aluminum steel layer; Aluminum steel layer away from steel core 1 is referred to as outermost layer aluminum steel layer 3, and the aluminum steel layer that promptly is positioned at the anti-icing snow transmission pressure outside is an outermost layer aluminum steel layer 3.In four layers of aluminum steel layer 2; The direction of lay of adjacent two-layer aluminum steel layer is opposite; And outermost layer aluminum steel layer 3 direction of lay are dextrad; In the present embodiment, the surface of the aluminum steel that outermost layer aluminum steel layer 3 is adopted is coated with the coating layer 4 that embodiment 1～6 described anti-ice and snow coating forms through embodiment 7～12 described methods.Except that the aluminum steel difference that outermost layer aluminum steel layer 3 is adopted, other structure and the making method of anti-ice and snow transmission pressure are identical with the structure and the making method of existing transmission pressure.
See also Fig. 2, be the sectional view of the anti-ice and snow transmission pressure of another kind.There are three layers of aluminum steel layer 2 in the outside of steel core 1, and the cross-sectional shape of the aluminum steel that outermost layer aluminum steel layer 4 is adopted is " ladder " shape.The same coating layer 4 of making on the surface of the aluminum steel of " ladder " tee section; The anti-icing paint that coating layer 4 is adopted is the anti-icing paint that obtains through embodiment 1～6 said method, and coating layer 4 is the surfaces that are produced on aluminum steel through embodiment 7～12 described methods.In addition, other structure and the making method of anti-ice and snow transmission pressure are identical with the structure and the making method of existing transmission pressure.
Because the surface of the aluminum steel that outermost layer aluminum steel layer 3 is adopted is coated with anti-icing paint; And anti-icing paint is to have that contact angle is big, the less super-hydrophobicity material of roll angle; Water (sleet) can be destroyed attached to the condition on the aluminum steel, thereby the adhesive power of icing and aluminum steel can be significantly reduced.Therefore the outermost layer of transmission pressure adopts the aluminum steel coiling that is coated with anti-icing paint, and water (sleet) can not be attached on the transmission pressure, thereby reduces the possibility that the transmission pressure surface forms ice sheet, and then reduces the influence that transmission pressure receives the ice and snow disaster.This anti-ice and snow transmission pressure is compared with methods such as traditional heating deicing, mechanical deicings; The characteristic that the persistence that can obtain to put things right once and for all is prevented icing; And do not need to have a power failure, not consumed energy, do not increase the workload of line upkeep, thereby reduce the maintenance cost of transmission pressure.
Certainly; The shape of the cross-sectional shape of aluminum steel in Fig. 1 and Fig. 2; The cross-sectional shape of the aluminum steel that also can outermost layer aluminum steel layer 4 among the embodiment 3～6 be adopted is as required processed like " Z " shape, " S " type etc., and the anti-icing paint of promptly processing with the method for the invention also can be coated on the lead of other different cross section shape.
In addition, the Stability Analysis of Structures of the anti-ice and snow transmission pressure of making through aforesaid method, the collision in transportation, in use gentle breeze vibration, wave and situation such as bending under, all can not destroy the coating layer on transmission pressure surface.
Need to prove; The foregoing description is the surface that anti-icing paint is coated on aluminum steel; Yet the present invention also can be coated on anti-icing paint the surface of the lead of processing such as other electro-conductive materials such as copper cash; Correspondingly, the outermost layer of transmission pressure also can adopt other electro-conductive material that is coated with anti-icing paint to process.And; When the lead of processing at other electro-conductive materials such as adopting copper cash is made anti-ice and snow transmission pressure; Can pass through embodiment 7～12 described methods equally; To be coated on the surface of copper cash by the anti-icing paint that the described method of embodiment 1～6 is made, and the identical performance of anti-ice and snow transmission pressure that provides of acquisition and the foregoing description.
It is understandable that above embodiment only is the illustrative embodiments that adopts for principle of the present invention is described, yet the present invention is not limited thereto.For the one of ordinary skilled in the art, under the situation that does not break away from spirit of the present invention and essence, can make various modification and improvement, these modification also are regarded as protection scope of the present invention with improving.
