Problems solved by technology

[0002] At present, some existing civil air defense doors are usually fixed in the open position. When the civil air defense doors are overhauled, there is no decorative layer on the outside, which will completely expose the maintenance site and affect the maintenance site.
At the same time, the civil air defense door is made of steel plate, but due to the defects of the steel plate itself, such as: the surface is easy to wear, the strength is low, the service life is short, and the oxidation resistance is poor, rust will occur for a long time, which not only affects the appearance, but also destroys the structural strength , reduce service life, etc.

preparation example Construction

[0057] Wherein, the pearlescent powder is white pearlescent powder, and the preparation method comprises the following steps:

[0058] 1) Add bismuth oxide solution and hydrochloric acid solution with a mass fraction of 46%-48% into a beaker, stir evenly, and heat at 300°C-400°C until the liquid evaporates completely; the molar ratio of bismuth oxide solution to hydrochloric acid solution is 1:15- 1:18;

[0059] 2) be cooled to room temperature;

[0060] 3) Add deionized water into the beaker, stir evenly, and filter the suspension suspended in the upper layer;

[0061] 4) Then add deionized water to wash until the pH value is 6-7;

[0062] 5) Drying at 100°C-120°C for 5-6 hours to obtain white pearlescent powder.

[0063] The composition of preferred three kinds of steel plates in the present embodiment;

specific Embodiment 1

[0064] The composition and mass percentage of the steel plate are: carbon: 0.22%, boron: 0.32%, palladium: 0.52%, selenium: 0.02%, arsenic: 0.02%, rubidium: 3.23%, vanadium: 0.45%, titanium: 5.36%, copper: 6.63%, tin: 4.57%, chromium: 8.7%, molybdenum: 0.06%, nickel: 8.78%, barium: 0.36%, magnesium: 3.42%, neodymium: 3.21%, promethium: 0.25%, praseodymium: 0.45%, balance is Fe and unavoidable impurities;

[0065] The surface of the steel plate is sprayed with an anti-corrosion coating and an anti-oxidation coating; the anti-corrosion coating consists of components A, B and C; component A is calculated in parts by mass: epoxy modified silicone resin : 20 parts, talcum powder: 16 parts, butyl rubber: 10 parts, graphite powder: 5 parts, lauryl acrylate: 11 parts, ceramic powder: 1 part, pearl powder: 3 parts, toluene: 1 part, perchloro Ethylene: 10 parts, methacrylic acid: 18 parts; component B by mass parts: dibutyl phthalate: 20 parts, rutile titanium dioxide: 10 parts, epoxy ...

Abstract

The invention discloses a civil defense door. The technical problem to be solved is the shortcoming during civil defense door maintenance in the prior art. According to the technical scheme, the civil defense door comprises a door frame, a civil defense door leaf and a disguise door leaf. The civil defense door leaf is rotatably arranged on the door frame and the rotating angle is 0-90 degrees. The disguise door leaf is rotatably arranged on the door frame and the rotating angle is 0-270 degrees. The civil defense door has the advantages that the disguise door leaf is added to the civil defense door, so that the shortcoming during the civil defense door maintenance is effectively overcome.

Description

technical field [0001] The invention relates to the field of civil defense doors, in particular to civil defense doors. Background technique [0002] At present, some existing civil air defense doors are usually fixed in the open position. When the civil air defense doors are overhauled, there is no decorative layer outside, which will completely expose the maintenance site and affect the maintenance site. At the same time, the civil air defense door is made of steel plate, but due to the defects of the steel plate itself, such as: the surface is easy to wear, the strength is low, the service life is short, and the oxidation resistance is poor, rust will occur for a long time, which not only affects the appearance, but also destroys the structural strength , reduce service life, etc. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the defects of the prior art civil air defense door mentioned in the background te...
