Problems solved by technology

[0003] Fires on aircraft carriers and warships will cause the ammunition they carry to be baked, and the energetic materials in the ammunition are extremely sensitive to external thermal stimulation. When a certain temperature is reached, the ammunition may self-ignite or explode, and due to the The ammunition on the aircraft carrier is dense, so it is very easy to cause the ammunition to explode, triggering chain explosions, seriously endangering the safety of ships and personnel, and causing huge economic losses

Abstract

The invention discloses a novel flame-retardation and heat-insulation protective coating and a preparation method thereof. The coating comprises, by weight, 30-50 parts of fireproof and flame-retardant resin, 20-40 parts of modified flame retardant resin, 9-24 parts of a carbon forming agent, 8-23 parts of a flame retardant, 3-8 parts of a foaming agent, 30-70 parts of a heat insulating filler, 0.5-2 parts of an assistant and 10-18 parts of a solvent. The coating prepared in the invention has the advantages of good fireproof and flame-retardant property, good heat insulation performance, goodmechanical properties, low heat conduction coefficient, high specific heat capacity, and realization of large-scale production.

Description

technical field [0001] The invention relates to the technical field of special coatings, in particular to a novel flame-retardant and heat-insulating protective coating and a preparation method thereof. Background technique [0002] In modern warfare, warships, aircraft carriers and other combat platforms are equipped with various types of weapons. In order to improve combat capabilities, the energy and power of weapon models are getting higher and higher, which brings about an increase in security risks. After World War II, fire and explosion are a very common type of ammunition accidents, and foreign troops have always regarded this kind of accident as the "number one enemy". Ships and aircraft carriers are floating weapon bases with high concentration of danger. Many ammunition, aircraft, equipment, fuel, etc. are densely arranged and there are many crew members. In addition to artificial arson, there are many factors that cause fires on ships and aircraft carriers. Impr...
