Abstract

The invention relates to ultrasonic sealing paint used for preparing the insulated bag of the inner wall of a plane casing and a preparation method thereof. The ultrasonic sealing paint comprises main agglomerant, cross-linking agent, catalyzer, surfactant and solvent with the mass percentages: 25% to 75% of the agglomerant, 0.1% to 15% of the cross-linking agent, 0.1% to 10% of the catalyzer, 0.2% to 10% of the surfactant and 10% to 70% of the solvent, and total weight is 100. The pH value of the prepared ultrasonic sealing paint is 6 to 12, and the solid content of the ultrasonic sealing paint ranges from 10% to 65%; and the viscosity of the ultrasonic sealing paint ranges from 100 to 2000 cps. The paint disclosed by the invention has fine binding property and fine consistency with an insulation film, and has excellent thermostability, moisture protection, impact resistance and high strength after being solidified by ultrasonic sealing, therefore the multifunctional insulated sealing bag material of the inner wall of the plane casing is provided.

Description

technical field [0001] The invention relates to an ultrasonic heat-sealing coating and a preparation method thereof, in particular to an ultrasonic heat-sealing coating used for preparing an insulating bag on the inner wall of an aircraft casing and a preparation method thereof. Background technique [0002] Although the global commercial aircraft industry has been affected by the current economic downturn, the long-term outlook of the global commercial aircraft industry remains positive. For the industry's most important product - narrow-body and wide-body aircraft for passenger and cargo transportation, that is, large commercial aircraft words, especially so. [0003] Forecasts for the next 20 years indicate that fare passenger miles, the driver of the global commercial aircraft industry, will grow by approximately 5% per year, which is twice the expected growth rate for the entire global economy. Orders for commercial aircraft in 2006 and 2007 also reached a new high of ...
