Problems solved by technology

[0006] However, when the above-mentioned fireproof coatings are used to prevent hydrocarbon fires, they cannot be used as fireproof coatings for steel structures against hydrocarbon fires because the film-forming substances cannot withstand the rapidly rising temperature and are quickly burned.

Embodiment 1

[0072] Please refer to the 4 fire retardant coating formulations of the present invention listed in Table 1. First, add the fluorine-containing polymer emulsion and the silicone-modified polyacrylate emulsion into the mixing tank according to the formula 1 in Table 1, and after stirring evenly, add the fire prevention additive (ammonium polyphosphate, melamine phosphate, melamine, pentaerythritol) , filler (titanium dioxide, zinc oxide, kaolin and aluminum silicate fiber) and propylene glycol, after stirring for 20 minutes, put it into a sand mill and grind it once, then add expanded graphite, mix evenly, and discharge into barrels. The performance of the fire retardant coating of the present invention obtained is shown in formula 1 of table 2.

Embodiment 2

[0074] According to formula 2 in Table 1, first add fluorine-containing polymer emulsion and silicone modified polyacrylate emulsion into the mixing tank, after stirring evenly, add fire prevention additives (ammonium polyphosphate, melamine phosphate, melamine, pentaerythritol), filler (titanium dioxide, zinc oxide, kaolin and aluminum silicate fiber) and propylene glycol, after stirring for 10 minutes, put it into a sand mill and grind it once, then send it into a ball mill and grind it for 15 minutes, then add expanded graphite, mix evenly, and discharge into barrels. The performance of the fire retardant coating of the present invention obtained is shown in formula 2 of table 2.

Embodiment 3

[0076] According to formula 3 in Table 1, first add fluorine-containing polymer emulsion and silicone modified polyacrylate emulsion into the mixing tank, stir evenly, add fire prevention additives (ammonium polyphosphate, melamine phosphate, melamine, pentaerythritol), filler ( Titanium dioxide, zinc oxide, kaolin and aluminum silicate fibers) and propylene glycol, after stirring for 30 minutes, put into a ball mill to grind one pass, then add expanded graphite, mix evenly, discharge and load into barrels. The properties of the fire retardant coating of the present invention are shown in formula 3 of table 2.

Abstract

The present invention relates to one kind of fire-proof paint with high hydrocarbon fire resistance for steel structure and its preparation process. The fire-proof paint has filming material comprising fluoric polymer emulsion and organosilicon modified polyacrylate emulsion, composite fireproof assistant comprising melamine and pentaerythritol, expanding agent comprising melamine phosphate with excellent carbon forming performance and foaming performance and expandable graphite, heat resisting stuffing comprising zinc oxide, titanium dioxide, kaolin aluminum silicate fiber, and filming assistant propylene glycol. It can bear hydrocarbon fire with high temperature raising speed, and has fire resisting limit up to 90 min, simple preparation process, low cost and wide application.

Description

technical field [0001] The invention relates to a fireproof coating, especially a steel structure coating for preventing hydrocarbon fire and a preparation method thereof. Background technique [0002] There are many types of existing steel structure fireproof coatings, which can be divided into three types according to their material forms: water-based, solvent-based and powder-type; according to the thickness of the coating, they can be divided into three types: thick type, thin type and ultra-thin type; The mechanism can be divided into three types: thermal insulation type, expansion type and non-expansion type. At present, the commonly used fireproof coatings for steel structures are mainly classified into three types: thick type, thin type and ultra-thin type. Among them, ultra-thin type fireproof coatings have better fireproof performance and decorative performance, which is the development direction of fireproof coatings. [0003] When a fire breaks out in a building...
