Description
Technical field
The present invention relates to automobile chassis coating process, specifically truck chassis entirety lacquer spraying technique method.
Background technology
In order to meet requirement of the user to commercial chassis Corrosion Protection high standard, domestic and international commercial car manufacturing enterprise is wide
The general anticorrosion that commercial chassis is carried out using all kinds of anti-corrosion measures, its technical process are typical for longeron punching press (roller
Pressure) -- vehicle frame riveting-electrophoresis-general assembly-vehicle delivers user, it is known that the reason for, electrophoretic techniques is at corrosion-resistant aspect
There is the advantage for being difficult to go beyond, but film-forming resin, based on epoxy resin, its benzene compounds is ultraviolet wavelength 200-400um's
It is easy to that electron transition occurs under light (especially wavelength 231um) irradiation, causes molecule chain break, cause electrodeposited paint film ageing-resistant
Poor performance, long-time sunlight are also easy to produce film efflorescence, loss of gloss.Even if with the development of technology, there is primer-topcoat in one
Electrophoretic coating, also only increase the good acrylic resin of a part of UV resistance in film forming matter epoxy resin, utilize two
Person's surface tension is different, and in baking process, epoxy resin sinks to following, and acrylic resin floats on characteristic above, lifting electricity
Swimming paint film ageing-resistant performance, but it is larger with user's request gap on the whole.
Traditional paint line carries out chassis when integrally painting, and need to consider to paint, dry, Qiang Leng, the factor such as emptying, total
16-18 stations, extreme influence general assembly assembly technology arrangement, and wire harness, rubber parts etc. need to be taken using serial arrangement between entrucking
Stoving process temperature can not be adapted to, can only be assembled after spray painting.Traditional bottom checks and regulates body lacquer spraying technique, can only be connected in parallel on general assembly assembling
Line, using offline spraying coating process mode, streamline requirements of mass production can be met.
The content of the invention
A kind of purpose of the present invention, in that overcome disadvantages mentioned above and deficiency, there is provided truck chassis entirety lacquer spraying technique side
Method, applied by the application of low temperature carbamide paint, two-component polyureas spraying equipment and invention makes masking material, realize truck bottom
Body spray painting is checked and regulated to connect production for line with truck general assembly.
Truck chassis entirety lacquer spraying technique method of the present invention, comprises the steps：
(1) polishing is carried out to the truck chassis for station of polishing to automatic transport to clean；
(2) covered using masking material to spray painting position can not be carried out；
(3) manually truck chassis is lifted to special sled and automatic transport to paint spray booth；
(4) paint mixing is carried out using accurate proportioning mixing apparatus, it is artificial to carry out chassis spray painting；
(5) frame chassis automatic transport to the drying chamber after the completion of painting is dried.
(6) manually lift to assembly line, unload masking.
The step (2) uses special masking material, is that refractory polyethylene transparent membrane and antistatic recycle
Nylon covers bag, to different valve class, stainless steelwork, electrical harness and the coating that need not be painted on truck chassis
Part etc. is covered.
The step (4) uses low temperature drying carbamide paint, and its resin component is to be modified asparatate ester paint, and 1500
Hour neutral salt spray, no foaming, corrosion；Artificial ageing in 1500 hours, aberration 0.8, loss of gloss 1%；Drying property 15-19min, 50
DEG C, fingertip is done, and meets online series connection fast low temperature stoving process requirement.
The step (4) carries out carbamide paint premix using accurate proportioning mixing apparatus, meets that carbamide paint spray painting requires.
The step (4) carries out coating premix using accurate proportioning device Promix 2KE equipment, and two-component ratio is 1:
(3~8).
The step (2) also includes being covered color-registering part using masking material, after drying is dried, extracts masking material
Material can be recycled.
A kind of process integrally painted on general assembly line series connection chassis of the present invention, technique effect is such as
Under：1st, design, making and the debugging of chassis entirety painting line.Carry out the feasible research for overall painting line of being connected in assembly shop,
Based on vehicle chassis salt spray resistance and weatherability performance purpose is improved, creativeness has carried out the craft cloth of tandem entirety painting line
Office, can fully be combined with total coating process, and the pitch-dark part in nearly all chassis is assembled into bottom before engine and driver's cabin assembling
Secondary spray painting is carried out on disk, realizes the maximization of spray painting area；Bottom pressure spray process realizes that chassis is sprayed as a total coating process part
Lacquer craftwork is seamless involvement total coating process, formation process design, integrally connected painting line for First truck chassis；2nd, it is fast
It the exploitation of dry type carbamide paint, can ensure to reach surface drying after 50 DEG C of drying 15min are offline, and not influence general assembly subsequent work stations
Parts assemble；3rd, chassis entirety lacquer spraying technique technical research, present invention lifting truck chassis anti-corrosion and weather resistance meet high
Hold the high anti-corrosion high durable coating demand of truck.
Brief description of the drawings
Fig. 1 is a kind of truck chassis entirety lacquer spraying technique flow chart of the present invention.
Each symbol description：
1-masking station 2- hoist 3- paint spray booths 4-drying chamber, 5-hoist 6-unloads masking
Embodiment
The present invention is further described with example below in conjunction with the accompanying drawings.
Embodiment 1.Truck chassis entirety lacquer spraying technique method of the present invention, concretely comprise the following steps the technique mistake of the present invention
Journey is that truck chassis is polished-clean-cover-carbamide paint spraying-drying-transport-unloads masking.As shown in figure 1, truck
, with the man-handling of materials of hoist 2 to paint spray booth 3, sprayed after masking station 1 carries out vehicle chassis polishing, cleans and cover on chassis
Paint is indoor to carry out carbamide paint spraying using accurate proportioning mixing apparatus, is dried in automatic transport to drying chamber, after the completion of
Manually it is hoisted to hoist 5 and unloads 6 stations of masking, carries out unloading masking, technique is completed.
Concretely comprise the following steps：
The position that can not paint is covered with special masking material.
The truck chassis completed will be covered, premixed with accurate proportioning device Promix 2KE equipment, using artificial mark spraying
Painting mode spray polyurea coating, 40-50 DEG C of drying temperature, drying time 15-19 minutes.
It will be dried by the truck chassis of spraying, stoving process requirement is 40-50 DEG C of temperature, drying time 15-19
Minute.
The truck chassis for drying completion is hoisted to and unloads masking station, masking material is removed, is transferred to lower process.
Paint line production capacity can be effectively improved by carrying out truck chassis spray painting using the method for the invention, be increased
Truck chassis entirety antirust and weather resistance.Compared to equal technological effect Conventional cryogenic acrylic polyester spraying coating process, have with
Lower advantage：1) high-solid lower-viscosity characteristic, 30 μm of a thickness of spraying is realized, reduces spray station 50%, VOC emission reduces by 50%；
2) stoving process is reduced to 50 DEG C, 15min by 80 DEG C, 30min, reduces gas consumption 70%, reduces drying station 50%；3)
With total coating process is seamless merges, realize that emptying area cancels.
