Description
Technical Field
The invention belongs to the technical field of aluminum magnesium alloy boxes, and particularly relates to an aluminum magnesium alloy box paint spraying process.
Background
The draw-bar box is also called a traveling case and a luggage case, is a case which is carried when going out and is used for placing articles, is one type of luggage, and is usually used for placing clothes, personal care products and souvenirs required in journey. Most of the existing suitcases in the market are made of ABS or ABS + PC and pure PC, the aluminum magnesium alloy suitcases in the market are gradually popular in China in recent years, the existing aluminum magnesium alloy suitcases adopt an oxidation process, and an aluminum plate adopts oxidation treatment materials and is subjected to acid-base corrosion, so that the original hardness becomes soft, the thickness becomes thin, the collision with a concave surface and the scraping are easily caused, and the consumption requirements of people can not be met more and more.
The present invention has been made in view of the above circumstances.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides an aluminum-magnesium alloy box paint spraying process, which can improve the thickness of three-layer paint spraying under the condition of keeping the material of an aluminum plate unchanged, protect the surface of a box shell, have flexibility and avoid scratching, scratches and dents.
In order to achieve the purpose, the invention adopts the following technical scheme:
an aluminum magnesium alloy box paint spraying process comprises the following steps:
(1) cleaning and decontaminating the aluminum-magnesium alloy box body, spraying primer and baking;
(2) spraying color paint on the aluminum-magnesium alloy box body sprayed with the primer, and baking;
(3) and then spraying gloss oil, baking, grinding, polishing and cleaning.
Wherein, the box washs the decontamination: as the case shell has grease, dust, rust, corrosive substances and the like on the surface during the manufacturing, processing and storage, the performance, the appearance and the like of a coating film are directly influenced if the case shell is not removed, and the process mainly comprises the steps of oil removal, water washing, rust removal, water washing and drying.
Spraying a primer: the primer coating used as a sealing material has the effects of improving the anti-permeation capability of the coating, enhancing the protection of a substrate, stabilizing a metal surface layer, enhancing the adhesive force between a colored paint and the metal surface, ensuring the color uniformity of the colored paint coating, spraying the primer for three times on the substrate, sending the primer into a dust-free constant-temperature paint spraying room for drying each time of spraying, supplementing putty and polishing in the middle of spraying paint to improve the surface flatness, and selecting a washing primer or a phosphating primer, wherein the washing primer needs to be baked in the paint spraying room, and the phosphating primer can be naturally dried.
Spraying color paint: after the box shell is sprayed with the primer, a layer of colored paint is added to distinguish different colors, so that the attractiveness, the color degree and the thickness of the box shell are improved, and then the box shell is sent into a dust-free constant-temperature paint spraying room to be dried.
And (3) gloss oil spraying: the gloss oil can effectively enhance the external erosion resistance of the paint layer, protect the colored paint coating, increase the metallic luster of the colored paint color, have more bright appearance and capture the luster.
Polishing: the polishing is to remove burrs, rust, oil stains and dust on the surface of the substrate, remove coarse particles and impurities on the surface of the coating to obtain a flat surface, polish the smooth surface of the coating to a certain roughness and enhance the adhesive force of the coating.
Polishing: polishing cotton is adopted for polishing, so that the hand feeling and the smoothness after brushing are improved.
Further, before the primer, the colored paint or the gloss oil is sprayed, a curing agent and a diluent are added for oil-removing treatment.
Furthermore, according to the weight portion, 95-105 portions of primer, colored paint or gloss oil, 8-12 portions of curing agent and 150 portions of diluent.
The curing agent and the diluent in the invention are both the existing raw materials, the diluent can be water or gasoline, the curing agent can be vinyl triamine or m-phenylenediamine, and the adhesion force of the paint can be increased after the oil-removing treatment.
Furthermore, 100 parts of primer, colored paint or gloss oil, 10 parts of curing agent and 125 parts of diluent by weight.
Further, the baking temperature in the step (1) is 95-105 ℃, and the baking time is 8-12 min.
Further, the baking temperature in the step (2) is 95-105 ℃, and the baking time is 8-12 min.
Further, the baking temperature in the step (3) is 95-105 ℃, and the baking time is 8-12 min.
The baking of the invention is carried out in a baking room, the baking room can cause the case shell to be not scratch-resistant and easy to stick hands when the temperature is too low, and the case shell can be easy to crack when the temperature is too high, and the inventor finally determines that the temperature is 95-105 ℃ and the baking time is 8-12min through a large number of experiments, so that the best performance of the paint can be fully exerted.
The whole paint spraying process is carried out in a dust-free room, and the problem of dust spots on the box shell can be solved. The automatic spray table is adopted for spray painting, so that the product is sprayed uniformly and bright in luster, and does not have the phenomena of wavy lines, lacrimation and the like.
Further, according to the parts by weight, the primer comprises 23-27 parts of acrylic resin, 3-7 parts of adhesion promoter, 2-4 parts of extinction powder, 28-32 parts of butyl ester, 10-14 parts of cyclohexanone, 13-17 parts of methyl isobutyl ketone and 8-12 parts of propylene glycol methyl ether acetate.
Further, the colored paint comprises 10 to 25 parts by weight of titanium dioxide, 2.5 to 10 parts by weight of 2-butoxyethanol and 0 to 1 part by weight of tri-tert-butyl phosphate.
Further, the three-layer paint formed by spraying the primer, the color paint and the gloss oil has a thickness of 0.06-0.10mm, and preferably, a thickness of 0.08 mm.
According to the size of different luggage cases, the painting quality is different and the same. For example:
20 cun almag suitcase: 0.1 KG/primer; 0.15 KG/piece of colored paint; gloss oil, 0.15 KG/piece.
24 cun almag suitcase: 0.12 KG/primer; 0.17 KG/piece of colored paint; gloss oil, 0.17 KG/piece.
Compared with the prior art, the invention has the beneficial effects that:
according to the paint spraying process, under the condition that the aluminum plate material is kept unchanged, the thickness of three-layer paint spraying is increased to 0.08mm, the surface layer of the box shell is protected, and the box shell has flexibility and cannot be scratched, scratched or hit a concave; the product sprayed by the process is uniform, bright in luster and free of the phenomena of wavy lines, glossy oil lacrimation and the like.
