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 ...
