Specific embodiment
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case where, the feature in the embodiments of the present invention and embodiment can be combined with each other.
A kind of rail vehicle carbon steel vehicle anticorrosion structure, as shown in Figure 1, including the substrate 1 of car body, the substrate of the car body
1 surface is equipped with prime coat, and the best prime coat is modified epoxy prime coat.The prime coat thickness is at least 100
um.The best prime coat is with a thickness of 150um-180um.
It is equipped with the top coat layer positioned at primer layer in car body top and end, the best top coat layer is the poly- ammonia of acrylic acid
Ester top coat layer.
The sealant layer 5 positioned at primer layer, the best sealant are equipped in car body intermittent weld and corner part
Layer is SMP weld joint sealant layer.The thickness of sealant layer at the intermittent weld is higher than face of weld 1mm-2mm；The side
The thickness of the sealant layer of angular position is higher than substrate surface 1mm-2mm.
Anti-corrosion wax coating 6 is equipped in the inner wall of the cavity 2 of car body.
In order to improve anti-corrosion (protecting against shock) ability of chassis, the chassis lower part of the car body is equipped with damping coating layer.It is best
The damping paint film thickness is 2mm-3mm.
Thickness uses Q355GNH cold-reduced sheet in 3mm and steel plate below in the substrate 1 of car body, and thickness is greater than the steel plate of 3mm
Using Q355GNH hot rolled plate.
When carrying out anti-corrosion, the anticorrosion process of the car body of the utility model is as follows:
1) to the enterprising professional etiquette model of the selection of the raw material such as steel plate, since most of type chamber, intermittent weld are present in thin plate
In structure, therefore thickness uses Q355GNH cold-reduced sheet in 3mm and with lower thin sheet, and thickness is greater than 3mm steel plate using Q355GNH heat
Plate is rolled, the antiseptic property of material body is promoted with this.
2) car body process route is standardized, it is desirable that whole after the completion of automotive body welding to carry out blasting treatment, abrasive material is selected
S390 steel sand, sandblasting are robot sandblasting.For car body thin plate position sandblasting distance controlling in 0.9m-1m, the sandblasting of slab position
Distance controlling reaches Sa2.5 in 0.5m-0.7m, with this car body surface cleannes, and roughness reaches Ra12.5 um -32um, has
Effect promotes the adhesive force of sequent surface coating.
3) car body integral spray modified epoxy priming paint, then in car body top and end-spray acroleic acid polyurethane face
Paint, paint film overall thickness are controlled in 150um-180um；It is subsequent to spray aqueous damping coating, damping paint film in vehicle body bottom frame lower part
Thickness control hits ability in the anti-stone of 2mm-3mm enhancing chassis.In other words, there is modified epoxy priming paint+resistance at vehicle body bottom frame
Damping paint.In this way, subsequent spray in chassis lower part damps after integral spray priming paint.
4) preservative treatment is sealed to car body intermittent weld, corner part using SMP weld joint sealant, at intermittent weld
Bondline thickness is higher than weld seam 1mm-2mm, and corner part glue-line is higher than substrate 1mm-2mm.
5) high solid anti-corrosion wax coating is sprayed to cavity inner wall by fabrication hole using special hanging pot air gun.Anti-corrosion
Heating treatment is carried out to car body, antiseptic wax before wax spraying, antiseptic wax temperature rise reaches 50 DEG C, and viscosity can reach 1000 mPas-
1500mPas, car body dew-point temperature reach 45 DEG C or more, can effectively enhance the attachment of antiseptic wax spray pattern and itself and substrate
Situation.
It is worth noting that the promotion that successively carries out can reach vehicle antiseptic property of the step 3 of the present embodiment to step 5
Effect.Wherein step 3 bottoming, step 4 and step 5 are made according to vehicle operating condition to corresponding site on the basis of step 3
Strengthen；Step 5 is finally to prevent antiseptic wax from polluting to step 3 and step 4 construction environment, to influence application property
Energy.
As a result, by control to technological parameter, to the protection of weld seam, corner part and to cavity wax spray, in conjunction with work
The arrangement of sequence is reasonable, significantly improves anti-corrosion ability.
Sandblasting process optimizes cleannes and roughness, increases coating adhesion.Modified epoxy is also handed over carbon steel base material
Connection reaction, possesses stronger adhesive force.Subsequent roof, headwall polyurethane finish can increase the anti-ultraviolet aging of exposed parts
Energy.Chassis damping slurry spraying can enhance the resistance to moisture in bottom and anti-stone hits ability, and promote the sound insulation and noise reduction ability of vehicle.Between car body
Disconnected commissure, which applies, to be broken sealant and can enhance corrosion resistance at intermittent weld.Finally it can strengthen chamber in car body hollow anticorrosion with painting wax
Internal water-fast, salt spray resistance, by achieving the effect that completely cut off steam, air with this to car body hollow anticorrosion with painting wax.
