Abstract

The invention provides an efficient fireproof heat-insulating coating layer for a special compartment or shelter, wherein the coating layer is coated on the outer wall of a compartment or shelter steel plate (1), and an antirust matrix layer (2), a heat-insulating functional layer (3), an anti-burning functional layer (4) and a protective finish paint layer (5) are sequentially arranged on the outer wall of the compartment or shelter steel plate (1). The heat-insulating functional layer (3) is composed of a film forming matter a, a low-heat-conductivity-coefficient filler and a functional additive; the anti-burning functional layer (4) is composed of a film forming matter b, a dehydrating agent, a carbon forming agent and a foaming agent. Under the conventional working condition, the structure has the advantages of small thickness, light weight and no influence on the overall performance of an automobile; under flame burning, foaming and carbonization can be rapidly carried out, the foaming ratio is 40-50 times, and the coating layer is compact in structure, small in porosity, high in bonding strength, not prone to falling off, good in fireproof and heat-insulating effects and goodin rust-proof and corrosion-proof 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...
