To be better understood from, table 1 is exemplary to list specific optimum ratio, but the invention is not limited in any way.
The surface reconditioning of table 1 raw materials for varnish proportioning example
Meanwhile, the present embodiment sets multiple comparative examples,
Comparative example 1：For part material component is replaced with present the most frequently used component in the comparative example, raw material composition with
Mass fraction is calculated as following composition：3 parts of SB4102PM aluminum pastes, 36 parts of Petropols, 1.2 parts of WB-224 adhesion promoters and
0.3 part of levelling agent, solvent is made up of 25 parts of dimethylbenzene, 9.5 acetone, 15 parts of sec-Butyl Acetates, 10 parts of ethyl acetates.
Comparative example 2：Except plating silver resin selects 35 parts of acrylic acid modified polymerization beyond the region of objective existences, remaining composition is identical with ratio 2.
Comparative example 3：Except plating silver resin is from addition to 35 parts of cellulose acetate modified resins, remaining composition with match somebody with somebody the phase of ratio 2
Together.
Comparative example 4：In addition to 2 parts of hardening anti-wear agents are selected in anti scuffing agent, remaining composition is identical with ratio 1.
Comparative example 5：In addition to 2 parts of nano aluminium oxides are selected in anti scuffing agent, remaining composition is identical with ratio 1.
The preparation method of above-mentioned surface reconditioning paint is as follows：
1. the raw material for including following ratio of weight and number is weighed：Plating 31.0～42.0 parts of silver resin, 2.0～4.0 parts of aluminum paste,
Silver powder arrangement 0.28～0.5 part of agent, 1.0～3.0 parts of adhesion promoter, 1.2～2.5 parts of anti scuffing agent, levelling agent 0.1～
0.8 part and 53.0～59.0 parts of solvent；
2. aluminum paste pretreatment：Aluminum paste is disperseed with the 1/5～1/3 of total solvent, 12～24h is soaked, is stirred, added
Silver powder arrangement agent is uniformly dispersed, and obtains mixed liquor A, stand-by；
3. the preparation of paint vehicle：Plating silver resin is added into container, 2. gained mixed liquor A and attachment are made every effort to promote to sequentially add step
Enter agent, be uniformly dispersed with 1200-1600 r/min, add anti scuffing agent, remaining solvent and levelling agent, be uniformly dispersed and paint is obtained
Material；
Gained paint vehicle can be brushed in stainless steel surfaces, and for ease of using, efficiently coating, can further make spray painting, be related to operation
Including b is prepared into step in paint vehicle, 3. obtained paint vehicle is filtered, and in pouring into the inhalator jar equipped with agitation beads, is put and sealed after valve
Mouth, filling dimethyl ether propellant, cross after water-bath and install head, that is, spray painting is obtained, and can carry out spraying using common process and use.
Each proportioning paint in table 1 is made into spray painting by above-mentioned technique, railway vehicle air conditioner SUS304 stainless steel test specimens are sprayed at
Surface, sprays 3 times, and following performance tests are carried out after drying naturally：Outward appearance after range estimation spraying, is painted using the test of pencil determination method
As a result film hardness, salt spray test test anti-corrosive properties, method of drawing a circle test paint film adhesion grade see the table below 2.
Each proportioning paint performance test in the table 1 of table 2
Above-mentioned test result shows, containing dimethylbenzene, environmental pollution is larger, in operating process for the raw material that the paint vehicle of comparative example is used
Same pollution is big, affects larger to operator's health, and due to its proportioning not science, hardness of paint film is low, and resistance to marring is poor, anti-corrosion
Property is poor；Compared with comparative example, the surface reconditioning that the present invention is provided paint color and track train air-conditioning SUS304 stainless steel casings
Color form and aspect height is approximate, is immediate color, and metal sense is strong, and surface is as neat as wax after reparation, its hardness, Corrosion Protection
The paint being substantially better than shown in comparative example, each group distribution ratio science, reasonable, function admirable of this surface reconditioning with paint, can extensively fit
For stainless steel scratch, scratch, rub the repair processes such as wound, corrosion and commissure oxidation stain.
While comparative example 2, comparative example 3 are compared with proportioning 2, the hardness of paint film after being repaired with the paint vehicle of proportioning shown in proportioning 2
Higher, decay resistance is more preferable；
Simultaneously comparative example 4, comparative example 5 be compared with proportioning 1, case hardness after being repaired with the paint vehicle of proportioning shown in proportioning 1, anti-scratch
Hinder performance to greatly improve.
