Abstract
The invention discloses a manufacturing method of an impact-resistant civil air defense door, which comprises the following steps: A. manufacturing a mold: the method comprises the steps of selecting a carbon steel plate, manufacturing four side edges and a bottom edge by adopting a cutting mode, then connecting and fixing the four side edges and the bottom edge by adopting a welding mode, and finally polishing the inner surface and the outer surface of the carbon steel plate by adopting a handheld small-sized polisher. According to the invention, the impact-resistant layer, the heat-insulating layer and the fireproof layer are manufactured in a layered manner, so that the phenomenon of infirm pressing caused by different raw materials among the functional layers can be avoided, and the heat-insulating layer, the impact-resistant layer and the fireproof layer are connected through the temperature-resistant epoxy glue, so that the overall firmness of the door core is further ensured, meanwhile, the overall strength of the door core can be further ensured by the high-manganese steel plate, and the overall strength of the high-manganese steel plate can be further improved by the zirconium alloy protective layer, so that the protective door has super impact resistance.
Description
Technical Field
The invention relates to the technical field of civil air defense, in particular to a manufacturing method of an impact-resistant civil air defense door.
Background
The civil air defense is called as civil air defense, is measures and actions taken by governments for mobilizing and organizing people to defend against air attacks of enemies and eliminate future troubles, and the civil air defense and field air defense jointly form a national air defense system, which is an important component of modern national air defense, is an important aspect of national economy and social development, is important content of modern city construction, is social public welfare beneficial to the nation and people, and a civil air defense door is required to be used in civil air defense engineering.
Disclosure of Invention
The invention aims to provide a method for manufacturing an impact-resistant civil air defense door so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a manufacturing method of an impact-resistant civil air defense door comprises the following steps:
