Abstract
The invention discloses a roll line solution for repairing a surface coating of a railway vehicle seamlessly and a preparation method and application of the roll line solution. The roll line solution is prepared from 55-75 parts by weight of mixed dibasic acid ester (PME), 20-40 parts of ethylene glycol monoethyl ether acetate (CAC), 0-10 parts of butyl acetate, 3-10 parts of mono-component acrylic resin, 0.2-0.6 part of defoaming agent and 0.4-0.8 part of flatting agent. The preparation method comprises the steps of: firstly, weighing all components in the terms of weight proportion; secondly, putting all the components in a container, and rapidly and uniformly stirring; and finally, standing for 8-15min. During the use, a local defect part of the surface coating of the railway vehicle is conventionally treated and subjected to paint repair, then the roll line solution is sprayed for the first time in a connector position of a new paint film coating and an old paint film coating and is sprayed for the second time after 50-70s, and after the paint films are actually dried, the seamless effect of consistent appearances of the new coating and the old coating can be achieved. The roll line solution can ensure that no seam exists on the appearances of the new coating and the old coating through visual inspection by once repairing the local defect, thereby being especially suitable for the requirement of integrally consistent appearances of high-performance railway vehicles.
Description
Technical field
The present invention relates to the rail vehicle topcoating, refer to particularly a kind of rail vehicle top coat traceless repair roll line liquid and its production and use.
Background technology
The rail vehicle surface is after finishing oil paint coating, and often there is unavoidable local defect in coating surface, comprises sagging, coarse, pin hole, scuffing, pollution etc.Particularly for outlet or extraordinary railway freight-car that some high protection, high-decoration can require, its outside surface visible film defect does not allow to exist, and this just need to carry out paint film and repair.
What generally adopt for the processing of these defectives at present, is the again method of application of sectional repair or car load.The sectional repair method mainly is the roll line liquid of using on the market for small area sprayed surfaces such as automobiles.Because the impact that rail vehicle is bulky, external structure is complicated, oil paint coating is taked manual work, its top coat performance and automotive coatings have larger otherness and construction environment factor, enamelled coating outward appearance after the existing roll line liquid of employing is processed is obvious difference still, cause the vehicle overall appearance second-rate, can't satisfy the requirement that high quality rail vehicle coating is repaired.And integral body coating process is not only wasted a large amount of manpowers and material of paint again, the operating procedure time is long, cost is high, and can't guarantee that new defective no longer appears in the vehicle after the again application.This shows, adopt these two kinds of traditional treatment process all to be difficult to satisfy the consistent requirement of high-performance iron road vehicles overall appearance.
How in the rail vehicle external coating its local defect to be carried out disposable simple, quick, effectively reparation, to avoid repeating repairing and again application of integral body, be the difficult problem that the railway scientific research personnel attempts to solve always.
Summary of the invention
The object of the present invention is to provide a kind of rail vehicle top coat traceless repair roll line liquid and its production and use.After adopting this roll line liquid that local defect is carried out disposable reparation, can make new and old appearance of coat range estimation seamless, thereby adapt to the consistent requirement of high-performance iron road vehicles overall appearance.
For achieving the above object, the rail vehicle top coat traceless repair roll line liquid that the present invention develops is formed by 55 ~ 75 parts of mixed dibasic acid esters (PME), 20 ~ 40 parts of ethylene glycol ether acetates (CAC), 0 ~ 10 part of butylacetate, 3 ~ 10 parts of single-component acrylic resins (GM-1), 0.2 ~ 0.6 part of defoamer, 0.4 ~ 0.8 part of flow agent assembly by weight ratio.
As preferred version, this roll line liquid is formed by 60 ~ 70 parts of mixed dibasic acid esters, 25 ~ 35 parts of ethylene glycol ether acetates, 5 ~ 10 parts of butylacetates, 3 ~ 8 parts of single-component acrylic resins, 0.2 ~ 0.5 part of defoamer, 0.4 ~ 0.6 part of flow agent assembly by weight ratio.
Further, described defoamer is selected a kind of in polydimethylsiloxane class, polyethers or the higher alcohol defoamer; Described flow agent is selected a kind of in acrylic acid or the like, the silicone based or fluorocarbon class flow agent.
Above-mentioned rail vehicle top coat traceless repair is as follows with the preparation method of roll line liquid: take by weighing by weight ratio first 55 ~ 75 parts of mixed dibasic acid esters, 20 ~ 40 parts of ethylene glycol ether acetates, 0 ~ 10 part of butylacetate, 3 ~ 10 parts of single-component acrylic resins, 0.2 ~ 0.6 part of defoamer, 0.4 ~ 0.8 part of flow agent, then all put in the container, rapid stirring is even, left standstill again 8 ~ 15 minutes, and namely can be used as finished product and use.
As preferred version, the time of described rapid stirring is controlled at 3 ~ 7 minutes.
Above-mentioned rail vehicle top coat traceless repair is such with purposes or the using method of roll line liquid: after conventional processing and touch-up paint are carried out in rail vehicle top coat local defect position, spray for the first time roll line liquid at new and old paint film coating interface position immediately, after 50 ~ 70 seconds, spray for the second time again roll line liquid, after paint film is done solid work, can reach the consistent seamless effect of new and old appearance of coat.
As preferred steps, for the first time spray roll line liquid after, after 60 seconds, spray again roll line liquid for the second time.
The mechanism of action of the present invention is described below: the roll line liquid of developing is combined by evaporation rate slower high boiling point strong solvent mixed dibasic acid ester (PME) and ethylene glycol ether acetate (CAC), the comparatively faster solvent acetic acid butyl ester of evaporation rate and single-component acrylic resin (GM-1), defoamer, flow agent, the dual-component coating that strong solvent mixed dibasic acid ester (PME) and ethylene glycol ether acetate (CAC) use the rail vehicle surface has good dissolving power, can effectively eliminate coating cloud particle and the aberration of coating interface; The adding of comparatively faster solvent acetic acid butyl ester of volatilizing can be controlled evaporation rate and the dissolving power of roll line liquid integral body, guarantees not occur that strong solvent because of slow vaporization too much causes stings end phenomenon; And the adding of single-component acrylic resin (GM-1) can guarantee the glossiness of coating interface paint film, alleviates the glossiness difference between new and old paint film; These active princlples and defoamer, flow agent synergy can make new and old coating paint film merge, and eliminate more coarse elaioleucite, vaporific limit or mandarin duck aberration, make paint film transition nature, make new and old paint film combine together.
The invention has the advantages that: the powerful double solvents that the roll line liquid of developing uses when being a kind of sectional repair, it is comprised of strong solvent and the Weak solvent of different rate of volatilizations, can form the gradient of evaporation rate and dissolving power, thereby can in the sectional repair process of rail vehicle top coat, make old paint film dissolving, with new paint film again levelling, form the paint film of color homogeneous.And technique of the present invention is simple, simple operation, can once finish the film defect reparation, avoids repeating repairing and again application of integral body, effectively reduces painting cost.Simultaneously, owing to eliminated the repairing vestige, can significantly improve the ornamental of paint film, guarantee good appearance, be particularly suitable for height protects, high-decoration can require outlet or extraordinary railway freight-car.
