Abstract

The invention provides a high-efficiency fire-proof and heat-insulating coating for special carriages or shelters, which is coated on the outer wall of the carriage or shelter steel plate (1), and the outer wall of the carriage or shelter steel plate (1) is in turn an anti- Rust matrix layer (2), heat insulation function layer (3), anti-burning function layer (4), protective finish paint layer (5); the heat insulation function layer (3) is composed of film forming material a, low thermal conductivity filler , functional additives; the anti-burning functional layer (4) is composed of a film former b, a dehydrating agent, a carbon forming agent, and a foaming agent. Under normal working conditions, the structure of the present invention has the characteristics of thin thickness, light weight, and does not affect the overall performance of the car; under flame burning, it can quickly foam and carbonize, and the foaming ratio is 40 to 50 times. Dense, small porosity, high bonding strength, not easy to fall off, good fire and heat insulation effect, and also has good anti-rust and anti-corrosion performance.

Description

technical field [0001] The invention relates to the technical field of fire prevention and heat insulation, in particular to a high-efficiency fire prevention and heat insulation coating for special carriages or shelters. Background technique [0002] Special vehicles or shelters may face extreme flame environments during use, such as external gasoline, diesel and other combustible combustion environments. When the special vehicle or shelter is in such an extreme environment, in order to ensure that the internal equipment is within the normal operating temperature range, it is necessary to spray a fireproof and heat-insulating coating on the surface of the special vehicle or shelter skin. Today's fire-resistant coatings are mainly used in areas such as walls that do not have strict weight requirements. This type of coating is usually a foaming coating. When it encounters a flame, it will quickly foam to form a loose porous structure to block heat. And the flame air flow has...
