Abstract

The invention discloses a subway steel structure closed protective door. The subway steel structure closed protective door comprises a door frame and a door body. The door frame is made from a glass steel material. The door body is manufactured by means of the method that the middle of two layers of glass steel materials is composited with a lead boron polyethylene plate. Each glass steel material is composed of 72-85% of glass steel fibers, 18-25% of neutron shielding fibers and 10-12% of X and Gamma ray shielding fibers. Compared with the prior art, the subway door is low in self weight and high in strength, the door body is manufactured by means of the method that the middle of the two layers of glass steel materials is composited with the lead boron polyethylene plate, so that the subway door has a good radiation shielding effect; and the door frame and the door body adopt an SMC sheet stock compression molding forming preparation technology and a laminating technology, so that no crack and bubble exists in the glass steel materials and the lead boron polyethylene plate, and the mechanical property accordant with requirements can be achieved.

Description

technical field [0001] The invention relates to the technical field of subway door preparation, in particular to a subway steel structure airtight protective door and a preparation method thereof. Background technique [0002] With the rapid development of rail transit, various forms of subway compartment partition doors are used in rail transit projects. Existing subway doors are generally made of reinforced concrete, which makes the subway doors heavier. At the same time, the existing subway doors have poor radiation protection effects, and the door body materials do not meet the specified mechanical performance requirements. Contents of the invention [0003] The invention aims to provide a subway steel structure airtight protective door and a preparation method thereof. [0004] The present invention provides following technical scheme: [0005] An airtight protective door of subway steel structure, characterized in that it includes a door frame and a door body, the ...
