The combined fire-resistant groove box disclosed by the invention comprises the fireproof plate of the groove box. The combined fire-resistant groove box is characterized in that the fireproof plate sequentially comprises a fireproof coating layer, a metal sheet layer and a thermal expansion layer from outside to inside; and the fireproof coating layer is prepared from epoxy resin as a base stock, and filler and pigment, a wetting dispersing agent, a defoaming agent and a thixotropic agent as assistants. The fireproof plate of the groove box disclosed by the invention expands in a fire, and is capable of blocking the fire and isolating heat; the condition that the groove box inside the fireproof plate is protected, and a cable in the protected groove box further run after in the hydrocarbon fire for a certain period of time is ensured; finally the reuse effect is reached; the combined fire-resistant groove box is especially suitable for the hydrocarbon fire, high in fire-resistant limit, simple to construct, and convenient to repair and dismantle, can play a role in dual protection, and can be repeatedly used.
Description
Technical field
The invention belongs to fire-retardant material field, relate to a kind of combined fireproof groove box and the groove box PLASTIC LAMINATED of resisting hydrocarbon fire.
Background technology
For different combustiblematerialss and burning-point, fire can be divided into different grades.The ordinary combustible such as fiber and xylogen is according to the burning of standard heating curve, and it can be warming up to 1000 DEG C in 90min; Petroleum chemical enterprise's particularly hot oil pump district presence of fire due to the damage of mechanical seal, then its combustiblematerials mostly is pure CH compound, belongs to hydrocarbon fire, and its heat-up rate is fast, flame temperature is high, can be warming up to 1100 DEG C in 6min.In addition, for different buildings and place, the fire resistance for fire-retardant material requires also not identical.For large scale industry facilities such as petroleum chemical enterprise, nuclear energy power plant, military installations, the redundant system of its inside needs to ensure that under hydrocarbon fire 3 hours water, gas and electricities are continuous, particularly for the fire-resistant groove box for encapsulating the pipeline such as communication link, electric wire, usually require that the fire-retardant material on its surface can realize following requirement of shelter in a fire: the cable not power-off of fire-resistant groove box in hydrocarbon fire burns 3 hours in fire-resistant groove box ensureing its inside; After concrete on fire removes fire-retardant material, protected groove box and Internal cable can continue to use; Size is as far as possible thin, saves space; Heat insulation while fire-resistance.
And fire-resistant groove box used in the market comprises the protected groove box being equipped with cable and the PLASTIC LAMINATED be arranged on outside groove box, groove box PLASTIC LAMINATED generally has following several: 1. metal trough box, this kind of groove box is the combined elbow being processed into direct through groove box and different shape with means such as steel plate, aluminium sheet, stainless steel plate bending welding, again through combining, though this kind of groove box has the advantage of good rigidly, ubiquity or corrosion-resistant or body are heavy, involve great expense, flame retardant effect is undesirable; 2., with the glass fibre reinforced plastic groove box of epoxy resin and glasscloth manual pasting, though this kind of groove box has good erosion resistance, there is technique coarse, production efficiency is low, intensity difference, work-ing life are short, reach the excessive shortcoming of fire-resistance standard thickness; 3. be coated with frie retardant coating in steel shell, the fire-retardant fireproof groove box that in-built flame-retardant board and flame screen are formed, though flame retardant effect increases, but skin is directly frie retardant coating, and antiseptic property improves without essence, because antiseptic property is poor, time is slightly long, frie retardant coating layer may also not have enough time to play a role and is just corroded partly or entirely, and this constructed value height is short for work-ing life, has simultaneously yet and reaches the excessive problem of fire-resistance standard thickness.Use conventional frie retardant coating to be coated on groove box surface simultaneously and obviously can not meet requirement to fire-resistant, heat insulation, the protection against corrosion of fire-resistant groove box etc. in hydrocarbon fire, needing a kind of can to realize in hydrocarbon fire of exploitation badly can the groove box PLASTIC LAMINATED of cable in available protecting groove box.
Summary of the invention
