Abstract
The present invention discloses a container, and the body of the container consists of a metal substrate and a metal basal material. The inner surfaces and the outer surfaces of the metal substrate and the metal basal material are coated with at least one paint layer. At the same time, the present invention also provides a method for manufacturing the container.
Description
Technical field
The present invention relates to a kind of tun and manufacture method thereof that material stores or transports that be used for, relate in particular to a kind of freight container and manufacture method thereof.
Background technology
General large-scale storage or transportation device, as the envelope of freight container, Fang Cang, trailer or superimposed trailer, its main components generally all is steel, for preventing corrosion, guarantee its normal service life, all will carry out coating to framing member in the mill and cover processing with coating.
The most frequently used coating is that solvent based coating is an oily varnish at present, owing in oily varnish, contain a large amount of organic solvents or diluent, they can constantly evaporate in air and the environment on every side in the coating film forming procedure and go, especially when the summer high-temperature operation, the volatility of organic solvent is very big, the work workshop of making is studded with unpleasant noxious odor, these volatilization gas of while run into naked light and are easy to burning, this promptly causes a large amount of wastes of solvent, also environment and health are exerted an adverse impact, and have bigger potential safety hazard.Simultaneously, environmental protection is all constantly being strengthened in countries in the world, environmental regulation as China is made explicit stipulation to the improvement of ' three wastes ' (waste gas, waste liquid, waste residue), to not meeting effluent standard and administering ineffective enterprise and make severe punishment, orders plant shutdowns etc. even as fine, suspending operations for consolidation.
At present, also there are some technical difficult problems in the application of water paint in freight container: at first, because the existence of moisture in the water paint, even if the surface treatment of process sanding, when the construction spraying, the surface of freight container still is easy to form rust spot; They are two years old, because with respect to organic solvent, water paint is as main dispersing medium with water, its volatilization, rate of drying than oily varnish slowly many, if press the existing fast pace coating of freight container construction technology, be difficult to guarantee its long-term antiseptic property, and can take place after the coating film forming moisture of part to be enclosed in the dry coating, cause the not good and disadvantage such as come off easily of filming of sagging, bubble, adhesive ability; Also have, freight container produces many weld seams in the welding assembly process, and these places are easy to generate disadvantages such as a rust, pin hole especially as the surface deficiency of metallic material when spraying.

2., metal substrate is drawn, is pressed into various types of corrugated platings;
3., the correspondence position of top beam of laterally, top beam and corner post is implemented welding, casing is welded into the frame body of hexahedron structure;
4., will make the metal substrate of all kinds corrugated plating and the hexahedron frame body is implemented welding, make the casing assembly.
Finishing in steps after, to finish paint in the interior spraying water-based, dry behind the levelling.
Sandblast to surface finish is the Sa2.5 level.
Water-based precoating rust proofing primer applicable viscosity is controlled at 10-30s, and the spraying build is controlled at 10-15 μ m, and spraying back bake out temperature is 70-120 ℃, and 1-5min is to surface drying in baking.
The applicable viscosity of the outer finish paint of finish paint and water-based is controlled at 20-80s in aqueous priming paint, water-based intermediate layer paint, the water-based, and each coating dry film THICKNESS CONTROL is at 30-50 μ m, and after the spraying, levelling 3-10min is dried 3-20min in 70-120 ℃ of drying room.
No gas automatic-spraying mode is adopted in the construction of water-based precoating rust proofing primer, and the employing nozzle diameter is 0.38-0.64mm, and spray pattern fabric width 200-360mm, high pressure pump intake pressure are 1-2kg/cm
2
Adopt the automatic and hand spray of the no gas mode that combines in the aqueous priming paint, water-based intermediate layer paint, water-based in the outer finish paint construction of finish paint and water-based, the employing nozzle diameter is 0.38-0.64mm, and spray pattern fabric width 200-360mm, high pressure pump intake pressure are 4-6kg/cm
2
To be based on main film forming substance respectively be a kind of in aqueous epoxy resins, waterborne polyurethane resin, the water-borne acrylic resin class coating to finish paint in outer finish paint of water-based precoating rust proofing primer, aqueous priming paint, water-based intermediate layer paint, water-based and the water-based, or at least two kinds compound in the aqueous epoxy resins, waterborne polyurethane resin, water-borne acrylic resin class coating.
The residing environment of workpiece after the spraying is set up drafting apparatus, makes that the flowing velocity of ambient air is 0.20-0.80m/s.
The residing environment of workpiece after the spraying is provided with desiccant, makes the humidity of ambient air not be higher than 75%.
Desiccant is at least at least a in these three kinds of solid driers of anhydrous calcium chloride, Roman vitriol and discolour silica gel.
The present invention is owing to adopted the freight container parts such as corrugated plating that contain the water paint layer, and its advantage is: (1) does not contain organic volatile matter, the living environment of community around having improved; (2) saved the expense that organic solvent and diluent are reclaimed and administer; (3) cleaning of Spray painting tool is convenient, as spray gun, join paint can, mixer etc., only needs a tap water just can clean up;
The present invention under the prerequisite of improving workman's construction environment, has improved the safety of operation in workshop owing to adopted new spraying method.Burn when meeting naked light, the probability of industrial accident such as blast reduces greatly than solvent-applied type coating.By spraying water-based precoating rust proofing primer, sealed the contact of metal substrate with airborne moisture/oxygen, effectively suppressed the formation of some rust; By coating prebake, make film in moisture evaporation must be more complete, thereby avoid or reduced occurring the not good disadvantage such as come off easily of filming of bubble, adhesive ability in filming; By the coating rust proofing primer of secondary sanding, deficiencies such as weld appearance point rust, pin hole have been prevented.Enhance productivity thereby reach, guarantee the purpose of product design.
