Ultra-thin water-based fireproof temperature control coating and preparation method thereof

Abstract

The invention relates to an ultra-thin water-based fireproof temperature control coating and a preparation method. The ultra-thin water-based fireproof temperature control coating comprises an energystorage connecting primer layer and at least one ultra-thin water-based fireproof temperature control coating which are sequentially coated, the energy storage connecting primer layer comprises the following components in parts by weight: an acrylic copolymer emulsion; hollow ceramic microspheres; and phase change powder microcapsules; the ultrathin water-based fireproof temperature control coating comprises the following components in parts by weight: a water-based styrene-acrylate copolymer; water; a mixing auxiliary agent; titanium dioxide; intumescent flame retardant powder; the phase change powder microcapsules; and a coalescing agent. the coating has the advantage of improving the heat blocking capacity of the fireproof coating. The preparation method comprises the following steps: brushing the energy storage connecting primer on the surface to be coated, continuously brushing the ultra-thin water-based fire-proof temperature control paint, and drying at normal temperature to obtain the water-based fire-proof temperature control coating. In addition, the preparation method has the advantage that combustion of the vehicle body is avoided.

Description

technical field [0001] The application relates to the field of fireproof coatings, in particular to an ultra-thin water-based fireproof temperature control coating. Background technique [0002] At present, the fire protection scheme of the battery compartment usually uses flame-retardant materials to construct the battery compartment, but this method has several disadvantages: one is that the doping of flame retardants will easily lead to a decrease in the strength of the vehicle body material, and at the same time cause the body The cost of materials has risen sharply; secondly, although the car body materials doped with flame retardants will not burn when subjected to high temperatures, they will soften and smoke, causing the battery car body to be scrapped and increasing the difficulty of recycling the car body; Moreover, for a large number of batteries that have been produced, it is impossible to use the method of adding a flame retardant to impart fire resistance.

Problems solved by technology

However, the non-combustible or flame-retardant coating can only provide short-term protection when the flame first occurs. Since it cannot block heat, it cannot continue to form protection, resulting in softening and burning of the plastic material of the battery compartment.

[0004] In view of the above-mentioned related technologies, the inventor believes that the non-combustible or flame-resistant fireproof coating can only provide short-term protection when the flame just occurs. Since it cannot block heat, it cannot continue to form protection, resulting in softening of the plastic material of the battery compartment. combustion
