Description
Technical field
The present invention relates to a kind of coating, more particularly, the present invention relates to a kind of abrasion-removable coating, simultaneously, the invention still further relates to a kind of preparation method and purposes of described abrasion-removable coating.
Background technology
At present, coating is used in civilian installation, equipment and the military affairs widely.
Be used in the coating on civilian installation, the equipment, can play provisional decoration function, but be difficult for wiping after using.
Be used in military coating and (be generally camouflage painting, be usually used in the camouflage of weapon, equipment) mostly be oil paint or water-insoluble coating, these coating have certain destruction to original paint film on weapon, equipment surface, often become permanent paint film after the use and be difficult for wiping, original paint film on weapon, equipment surface is difficult for maybe can't recovering.
Because of the uncertainty of manoeuvre training or operational environment and the conversion in season, make weapon, equipment to cover with paint, lacquer, colour wash, etc. to carry out adaptive camouflage according to actual needs, so the camouflage of weapon, equipment covering with paint operation is quite frequent.
As mentioned above, the coating on weapon, equipment surface can not be wiped at any time according to the needs of army, and therefore, existing coating is not suitable for using in the manoeuvre training of army or in fighting.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of abrasion-removable coating that is easy to wipe, its economic formula, and function is lasting; A kind of preparation method of this abrasion-removable coating is provided simultaneously, and this method technology is simple, and use equipment is few; Also provided simultaneously the purposes of this abrasion-removable coating, promptly adopted roller coat, brushing or spray these three kinds of traditional methods to form paint film at body surface.
For solving the problems of the technologies described above, abrasion-removable coating of the present invention, it comprises base-material, pigment, filler and auxiliary agent, and with respect to the abrasion-removable coating of per 100 weight parts, the weight part of each component is: base-material 59～61, pigment 34～36, filler 1.8～2.2, auxiliary agent 2.7～3.3.
Described base-material comprises alkali metal silicate aqueous solution and polyvinyl alcohol, and wherein the weight part of each component is: alkali metal silicate aqueous solution 50～51, polyvinyl alcohol 9～10.
Described pigment is any one in deep green pigment, light green pigment, khaki color pigment, the brown.Like this, be convenient to select as required corresponding color.
Described filler is a talcum powder.
Described auxiliary agent is flatting silica or antisettling agent.
The preparation method of this abrasion-removable coating, it comprises following processing step:
(1): pigment described in the claim 1 to 6 and filler are carried out fine grainding;
(2): at normal temperatures the pigment of fine grainding and filler and base-material, auxiliary agent are fully stirred, can make described abrasion-removable coating.
The fineness that described fine grainding will reach≤50 micron.
The purposes of this abrasion-removable coating is: adopt roller coat, brushing or spray these three kinds of traditional methods to form paint film at body surface.
The membrane formation mechanism of abrasion-removable coating of the present invention: when abrasion-removable coating is covered with paint, lacquer, colour wash, etc. at body surface, alkali metal silicate aqueous solution in the coating absorbs carbon dioxide in air, after reaction, separate out silica dioxide gel, silica dioxide gel drying and dehydrating gradually becomes silicon oxide and hardens, pigment is rolled in wherein, forms satisfactory coating.With the abrasion-removable coating that comprises the sodium silicate aqueous solution is example, and its film forming chemical expression is:
Na
2O·nSiO
2+CO
2+mH
2O→nSiO
2·mH
2O+Na
2CO
3
The hydrolysis mechanism of abrasion-removable coating of the present invention: under the effect of water, hydrolysis reaction easily takes place in abrasion-removable coating, its hydrolysis reaction more complicated.With the abrasion-removable coating that comprises the sodium silicate aqueous solution is example, and the chemical expression of its hydrolysis reaction is:
Na
2O·nSiO
2+mH
2O→2NaOH+nSiO
2·(m-1)H
2O
Therefore, when needs are removed abrasion-removable coating, only need water, wipe, clean up and get final product with cloth then the surface infiltration of coating 5～10 minutes, thus convenient, easily recover object surfaces, original paint film of body surface is not damaged yet.
This abrasion-removable coating has visible light and near-infrared camouflage performance (0.38～1.2 micron), physical and mechanical properties and workability excellent characteristics, and visible light and near infrared brightness and aberration meet the GJB798-90 standard.In addition, also have good acid and alkali-resistance, weather resistance, and nontoxic, harmless, free from extraneous odour, fire-retardant.
This abrasion-removable coating be highly suitable for the manoeuvre training of army or fight in weapon, equipment, military installations carried out camouflage provisional or should be acute cover with paint, lacquer, colour wash, etc., also can be used for the transient decoration of civilian installation, equipment.
In sum, the economic formula of this abrasion-removable coating, function is lasting, is easy to wipe; The preparation method of this abrasion-removable coating, its technology is simple, and use equipment is few; This abrasion-removable coating of many uses, adaptability is strong, and industrialization is used does not have obstacle.
Base-material in the abrasion-removable coating of the present invention, pigment, filler and auxiliary agent are commercially available product.
