Embodiment

[0018] Selection of required materials:

[0019] The thin wire mesh is selected from steel or stainless steel thin mesh that meets the requirements of HB1862-1993. In order to ensure the adhesion and fireproof effect, the basic size of the thin mesh mesh should not be larger than the thickness of the fireproof coating. Suggested preferred dimensions are as follows:

[0020]

[0021] Choose fire-resistant coatings and paints:

[0022] As the matrix resin of intumescent aviation fireproof composite material, the fireproof coating has good flexibility, adhesion and antirust ability, and the protective topcoat has good environment resistance and medium resistance ability. The main components of the fire retardant coating are high temperature resistant acrylic silicone resin, P-C-N intumescent flame retardant and asbestos chopped fiber, the ratio is about 3:5:1, and the main component of the protective topcoat is flame retardant modified acrylic polyurethane. At present, fire ...

Abstract

The invention belongs to the fireproof material technology, and relates to an expansive type aviation fireproof composite material for fire-preventing of an airplane structure, and a manufacture method of a fireproof composite material. The fireproof composite material can be singly manufactured or purchased in a finished product form, the mounting and replacement are relatively simple, and the required period is only 1 / 100 of the period for coating fireproof paint, the production period and maintenance period of the airplane are greatly shortened. The materials for manufacturing the fireproof composite material are materials in existence, so that the material cost cannot be greatly increased. The fireproof composite material is capable of expanding and foaming to isolate the flame and heat radiation when the airplane is on fire, and meanwhile the fixed shape can be maintained. When the thickness is 0.8mm, the fireproof composite material can be used for preventing fire for 15min and more at 1093 DEG C, and when the thickness is 0.5mm, the fireproof composite material can be used for preventing fire for 5min and more.

Description

technical field [0001] The invention belongs to the technology of fireproof materials, and relates to an intumescent aviation fireproof composite material and a manufacturing method thereof, which are used for fireproofing aircraft structures. Background technique [0002] Aviation fireproof coatings used in large and medium-sized aircraft and civil aircraft engine nacelles, APU cabins and other parts have defects such as very difficult construction and long drying cycle. The parts need to be disassembled during maintenance of the fireproof coating, and the removal and recoating period is very long, which affects normal use of the aircraft. Contents of the invention [0003] The object of the present invention is to provide an intumescent aviation fireproof composite material and a manufacturing method thereof that does not affect the normal use of the aircraft when the aircraft fireproof coating is maintained. [0004] The technical solution of the present invention is: ...
