Abstract
The invention discloses a processing technology of a civil air defense door frame, which comprises the following steps: firstly, removing rust on angle steels, splicing 45-degree splicing angles of four angle steels forming a door frame, and then welding and fixing; and secondly, performing stamping processing on the locking holes and the rib penetrating holes and welding the embedded pressing strips on the two longitudinal angle steels. The processing technology of the civil air defense door frame can improve the noise reduction effect of the civil air defense door frame and improve the anti-corrosion and anti-rust performance.
Description
The technical field is as follows:
the invention relates to the field of civil air defense doors, in particular to a processing technology of a civil air defense door frame.
Background art:
the existing civil air defense door frame is usually formed by angle steel in sequence splicing mode and is welded and fixed at the splicing position, the sound of the door frame is large when the civil air defense door is opened and closed, and the anti-rust and anti-corrosion performance is poor.
The invention content is as follows:
the technical problem to be solved by the invention is to provide a processing technology of a civil air defense door frame which is well matched with a civil air defense door and has better antirust and anticorrosion effects.
The technical scheme of the invention is to provide a processing technology of a civil air defense door frame, which comprises the following steps:
firstly, removing rust on angle steels, splicing 45-degree splicing angles of four angle steels forming a door frame, and then welding and fixing;
secondly, performing stamping processing on a locking hole and a rib penetrating hole and welding an embedded pressing strip on the two longitudinal angle steels;
thirdly, spraying an enamel glaze layer on the outer surface of the door frame and sintering at high temperature, wherein the enamel glaze layer is prepared from antimony white, kaolin, zirconium oxide, urea and deionized water;
and fourthly, spraying a modified damping rubber layer on the inner surface of the door frame, wherein the modified damping rubber layer is prepared from the following raw materials, by mass, 10 parts of butyl rubber, 6 parts of chlorinated butyl rubber, 5 parts of mica powder, 8 parts of titanium dioxide, 2 parts of zinc phosphate and 25 parts of modified organic resin.
The invention has the beneficial effects that: the door frame of the civil air defense door produced by the process has high strength, can reduce the noise when the civil air defense door is opened and closed, is corrosion-resistant and rust-resistant, and is dampproof, mildew-resistant and oxidation-resistant.
Preferably, a carbon fiber prepreg tape is wound outside the door frame, and the carbon fiber prepreg tape is pressed on the surface of the door frame through a press.
The specific implementation mode is as follows:
the invention will be further illustrated with reference to specific embodiments:
a processing technology of a civil air defense door frame comprises the following steps:
firstly, removing rust on angle steels, splicing 45-degree splicing angles of four angle steels forming a door frame, and then welding and fixing;
secondly, performing stamping processing on a locking hole and a rib penetrating hole and welding an embedded pressing strip on the two longitudinal angle steels;
thirdly, spraying an enamel glaze layer on the outer surface of the door frame and sintering at high temperature, wherein the enamel glaze layer is prepared from antimony white, kaolin, zirconium oxide, urea and deionized water;
and fourthly, spraying a modified damping rubber layer on the inner surface of the door frame, wherein the modified damping rubber layer is prepared from the following raw materials, by mass, 10 parts of butyl rubber, 6 parts of chlorinated butyl rubber, 5 parts of mica powder, 8 parts of titanium dioxide, 2 parts of zinc phosphate and 25 parts of modified organic resin.
For further improvement of strength, a carbon fiber prepreg tape is wound outside the door frame and is pressed on the surface of the door frame through a press.
