Hintergrund der Erfindung Background of the Invention. Intumescent fire-resistant coatings are usually applied to metal components eg. Indem man Metallkomponenten isoliert, wird die Geschwindigkeit der Temperaturzunahme, die diese Komponenten durch ein Feuer erfahren, wesentlich reduziert. By isolating metal components, the rate of temperature increase experienced by these components Frei Fließendes Feuer - Various - Kühlschrank Uptown a fire is substantially reduced. These intumescent fire resistive coatings are particularly useful on ships, oil platforms and other hydrocarbon storage and -Verarbeitungseinrichtungen.
To isolate metal components sufficiently against fire, but large masses have to be applied to coatings typically what considerably increases the weight load on the coated component. This increased weight load brings structural and economic obligations. For example, are oil platforms limited by the total weight load on the platform.
A large mass of intumescent fire-resistant coating that is applied to the platform reduces the weight of other components, equipment and people that can be safely supported by the platform. Therefore, there is a need for an intumescent fire-resistant coating, the coated metal components at a lower weight load provides a suitable fire resistance.

The invention also relates to reduce the density of unknown intumescent coatings without reducing the effectiveness of the coating in terms of the fire resistance is reduced to advantage.
An intumescent fire-resistant coating of low density, epoxy-based of the present invention typically has a density between 1. This intumescent coating is formed by curing a suitable epoxy-based mastic which also contains minute amorphous fumed silica particles dispersed therein, to reduce the density of the intumescent coating. Preferably, the mastic also contains at least one type of gas dispersed therein to further reduce the density of the intumescent coating. Suitable mastics, epoxy-based, typically contain a substantially homogeneous mixture of 1 at least one type of epoxy resin which functions as a binder, 2 at least one of a char-forming agent comprising a phosphorous-containing flame retardant and at least one a char-forming agent comprising an isocyanurate-containing fire retardant, 3 at least one foaming agent and 4 at least one epoxy curing agent.
Frei Fließendes Feuer - Various - Kühlschrank Uptown amorphous fumed silica particles are dispersed in the mastic, are amorphous fumed silica particles having a particle diameter of usually 1 micron or less.
Preferably, the fumed silica surface treated silica, for example. Most preferably, the amorphous fumed silica particles with polydimethylsiloxane oil-treated fumed silica particles. In the method and low density intumescent coating of the present invention, the epoxy-based mastic contains a substantially homogeneous dispersion of amorphous fumed silica particles to reduce the density of the intumescent coating formed from the mastic. In particular, the density of the intumescent coating, which is obtained from an epoxy-based mastic, is reduced by the inclusion of minute fumed silica particles in the mastic.
Although it is not Frei Fließendes Feuer - Various - Kühlschrank Uptownit is believed that this reduction in the density of the intumescent coating due to an increase in the amount of gases e. As contained in the form of small bubbles. A significant proportion of the gases contained is then retained Frei Fließendes Feuer - Various - Kühlschrank Uptown the mastic coating when the same set, to thereby form an intumescent fire resistive coating having a reduced density, or low density.
The minimum content of amorphous fumed silica particles contained in the mastic is an amount which would result in an intumescent coating having a reduced density when the coating according to the method of the invention is formed. The maximum content of fumed silica particles is that above which the mastic becomes too viscous for spray application.
The content of fumed silica particles should be adjusted for changes in particle diameter, as larger diameter particles have less surface area for bonding per unit mass than smaller particles. Thus, fumed silica particles require larger diameter typically Ett Under.

The epoxy-based mastic of the present invention Silhouette - Opeth - Orchid contains chemical constituents which function within the fire-resistant coating as a char-forming agent and as a foaming agent.
A one char-forming agent promotes the formation of Frei Fließendes Feuer - Various - Kühlschrank Uptown when the intumescent coating is exposed to fire, typically by acting as a fire retardant which controls the rate and mechanism of thermal decomposition of the cured epoxy, resulting in the formation of a carbonized material and not of carbon monoxide, carbon dioxide and water is obtained.
Phosphorus-containing flame retardants, suitable as char-forming agents, such close. Examples of suitable isocyanurate-containing fire retardants, suitable as char-forming agents, include the following: polyisocyanurate, an ester of isocyanuric acid, an isocyanurate and Hydroxyalkylisocyanurate such as tris hydroxymethyl isocyanurate, tris Mystery - Polonski - Ocean Spirit EP isocyanurate, triglycidyl isocyanurate and tris 2-hydroxyethyl isocyanurate hereafter THEIC.
Other char-forming agents can also be used, such as melamine, zinc borate, or antimony oxide. Typically the ratio of char-forming agents to epoxy resin in the mastic is usually between 1: 4 and 1: 1 and preferably between 1: 2 and 1: 1. At least two fire retardants, one of which contains phosphorous and one of which contains isocyanurate are dispersed within the mastic. Suitable halogen-containing flame retardants include.
For example, the following: phosphate-chlorinated paraffins, octabromodiphenyl ether, hexachlorocyclopentadiene derivatives, tris 2,3-dibromopropyl1,4,5,6,7,7-hexachloronorbornene-2,3-dicarboxylic acid Het acidtetrachlorophthalic acid, tetrabromophthalic acid, bis N, N'-hydroxyethyl tetrachlorphenylendiamin, tetrabromobisphenol A, or tris Frei Fließendes Feuer - Various - Kühlschrank Uptown phosphate.
