The invention discloses a testing method for the fireproof performance of a firewall sealant, belonging to the technical field of testing of material performance. The method comprises the following steps: igniting a combustor and allowing the flame temperature of the combustor to be maintained at 1050 to 1150 DEG C; then placing the combustor at one side, where the firewall sealant is located, of a test piece and allowing the scope of the flames of the combustor to cover 70 to 90% of the area of the flame-facing surface of the test piece; firing the test piece with the flames for 14 to 15 min; measuring the temperatures of the flame-facing surface and a back surface not facing flames of the central area of the test piece respectively, and drafting a temperature variation curves; and evaluating the fireproof performance of the firewall sealant according to testing phenomena or the variation curve of the temperature of the back surface not facing flames. The method can effectively evaluate the fireproof performance of the firewall sealant by testing a firewall preventing large-area flames and has the advantages of strong targeting performance, a high simulation degree and reliable evaluation results.
Description
Technical field [0001] The invention belongs to the technical field of material performance testing, and specifically relates to a method for testing the fire resistance of a firewall sealant. Background technique [0002] The firewall sealant is an important part of the aircraft firewall. It mainly plays a role of fire prevention and heat insulation, and can ensure the normal function of the firewall. [0003] In the prior art, the test methods for the fire performance of materials mainly adopt vertical burning, horizontal burning, 45° burning, or burning with alcohol blowtorch, etc. These methods use small specimens for testing on a static test bench, but for The test of large-area flame protection firewall is not applicable, and the fire protection performance of the firewall sealant cannot be effectively evaluated. Summary of the invention [0004] In order to solve the above-mentioned problems, the present invention provides a test method for the fire protection performance of...
