Abstract

The invention relates to a light weight porous melamine resin type border-crossing capturing material and a preparation method thereof. The preparation method comprises the following steps: (1) evenly mixing crystal water mineral powder, melamine-formaldehyde resin, a surfactant, and a curing agent according to a certain ratio to form stable slurry; (2) heating the slurry prepared in the step (1) to a temperature of 70 to 85 DEG C, rapidly adding a foaming agent, and carrying out curing reactions to form a light weight porous material; (3) drying the light weight porous material obtained in the step (2); (4) cutting the light weight porous material obtained in the step (3) according to the size requirements through hot cutting. The prepared capturing material has a good anti-freezing performance and overcomes the shortage of easily flammable property of common spraying organic substances.

Description

technical field [0001] The invention relates to the field of novel materials, in particular to a lightweight porous melamine resin transboundary capture material and a preparation process thereof. Background technique [0002] Aircraft stalling off the runway during takeoff and landing often leads to serious aviation accidents. In order to avoid such aviation accidents, active and passive capture methods can effectively prevent aircraft from rushing out of the runway safety zone and reduce accidents. Among them, the active capture adopts the aircraft parachute and hook lock system. This method is suitable for military aircraft with relatively small volume, more frequent takeoffs and faster speed. For large-scale civil aircraft, it is commonly used in the world to install the characteristic material arresting system (EMAS) at the end of the runway. [0003] The main functional unit of a performance material arresting system is the arresting bed. At present, the unit materi...
