Problems solved by technology

[0003] In the past, the emergency doors of many domestic simulator production institutions were roughly divided into two types. The first one was a metal door welded by aluminum alloy materials, also called a metal emergency door. The disadvantage was that the emergency door was deformed after repeated use. can only be scrapped
The second is to glue a layer of rubber on the basis of the aluminum alloy skeleton, which is called a rubber emergency door. After repeated use several times, the appearance is severely damaged and deformed, the life is relatively short, and the weight is heavy. Most of the flight attendants are young women. inconvenient

Abstract

The invention discloses a simulated aircraft self-adhered skin emergency door which is prepared from the following raw materials in percentage by weight: 50-66% of polyether, 0.30-0.40% of A-33, 0.02-0.06% of A-1, 0.4-0.8% of silicone oil, 4-8% of a foaming agent, 4-8% of ethylene glycol and 20-40% of modified MDI, totaling 100%. The framework and self-adhered skin of the simulated aircraft self-adhered skin emergency door disclosed by the invention are processed at a time, and the two are firmly adhered. The self-adhered skin belongs to one kind of polyurethane, has excellent wear resistanceand rebound resilience, avoids the problems of crack, deformation and the like during repeated use, and is high in corrosion resistance and oxidation resistance, long in service life, light in weightand low in production cost.

Description

technical field [0001] The invention belongs to the technical field of new material manufacturing, and in particular relates to a simulated aircraft self-connecting emergency door and a preparation method thereof. Background technique [0002] The emergency escape door of the simulated aircraft (also known as the self-receiving emergency door of the simulated aircraft) is a training process in which the trainers open the escape door and throw it to the ground for emergency evacuation of the passengers after simulating the emergency landing of the real aircraft. The middle emergency door needs to repeatedly run to the ground many times. [0003] In the past, the emergency doors of many domestic simulator production institutions were roughly divided into two types. The first one was a metal door welded by aluminum alloy materials, also called a metal emergency door. The disadvantage was that the emergency door was deformed after repeated use. Can only be scrapped. The second...
