The invention provides a phenolic resin / silicon dioxide compositeaerogel material and a preparation method thereof. The phenolic resin / silicon dioxide composite aerogel material has a nano-grid structure in which a silicon dioxide phase and a resin phase are mutually tangled. The phenolic resin / silicon dioxide composite aerogel material is prepared from a material containing an organic silicon precursor, a phenolic compound, an aldehyde compound and chitosan by virtue of a sol-gel method and supercritical carbon dioxide. According to the composite aerogel material, an organic phase and an inorganic phase are respectively continuous nano-scale tangle structures and are integrated with the mechanical property of organic aerogel and the thermal insulation property and fire resistance of silicon dioxide aerogel; and after the composite gel material with a thickness of 1cm is impacted by the 1300-DEG C flame of a blast burner for over 30 minutes, the falling and the separation of the inorganic phase are not caused, and meanwhile, the temperature of a protected side does not exceed 300 DEG C. The preparation method has the beneficial effects that the operation is simple, the reaction is safe and reliable, and the thermal insulation property and the fire resistance of the material can be regulated and controlled by simply changing the material proportion.

The invention relates to a manufacturing process of a common wall body construction member for a building and discloses a manufacturing process of a novel imitation wood heat insulation broken bridge wall body construction member, which comprises the following steps: taking a metal rod, extruding into a metal profile with a dovetail groove, using a strip penetrating machine to respectively penetrate two heat insulation strips into the dovetail groove for being pressed into a metal housing with an inner mold cavity, further arranging load-bearing supports with metal pipelines into the inner mold cavity of the metal housing, enabling the two load-bearing supports with through holes to be just hermetically arranged at two side ends of the inner mold cavity, enabling the load-bearing support with a drainage hole and the through hole to be arranged at the middle of the inner mold cavity, opening an injection hole on the metal housing, injecting a flame retardant polyester foaming agent into the injection hole, and further sealing the injection hole after the inner mold cavity of the metal housing is filled with the flame retardant polyester foaming agent which is filled through a diversion hole of the load-bearing support. According to the technical scheme of the invention, the fireproof performance is good, the effects of sound insulation and shock resistance are good, and the combined strength is high, thereby having great advantages.

Disclosed is a novel electromechanical thermal insulation and fire prevention protective device. The novel electromechanical thermal insulation and fire prevention protective device comprises a protective shell, a mounting frame, buffering frames and a protective device. The protective shell is fixedly installed on the surface of the mounting frame. The protective device comprises a thermal insulation device and a fire prevention device, wherein the thermal insulation device is arranged inside the protective shell, and the fire prevention device is arranged outside the protective shell. The fire prevention device comprises a fire prevention layer and a thermal insulation layer. The fire prevention layer comprises a fire prevention plate and an aluminum alloy plate, wherein the fire prevention plate and the aluminum alloy plate are connected together through flame retardance strips in the mode that the flame retardance strips penetrate through the fire prevention plate and the aluminum alloy plate. The thermal insulation layer is uniformly arranged on the surface of the fire prevention layer. The thermal insulation device comprises radiating pipes and cooling fins. Each buffering frame comprises a spring rod and a soft gasket, wherein each spring rod and the corresponding soft gasket are connected together through a connecting plate. The mounting frame is arranged at the bottom end of the protective shell. The novel electromechanical thermal insulation and fire prevention protective device can achieve the good thermal insulation and fire prevention capacity, can also conduct sufficient thermal dissipation and buffering protection on an electromechanical machine, prolongs the service life, is convenient to install and deserves promotion.

The invention relates to a fireproof cable bridge which comprises a cover plate, two C-shaped side plates with corresponding openings, a first phenol resin plate, two second phenol resin plates and a third phenol resin plate, wherein the first phenol resin plate is transversely paved on the upper end surfaces of installation portions of the C-shaped side plates, and a base plate is arranged on the upper end surface of the first phenol resin plate. A protrusion portion is arranged on the upper end surface of a supporting portion of each C-shaped side plate, a corresponding groove is arranged on the lower end surface of each supporting portion at the position corresponding to the protrusion portion, the cross sections at the upper ends of the second phenol resin plates in the longitudinal direction are matched with the grooves, and the lower end surfaces of the second phenol resin plates butt against the upper end surface of the base plate. Steps are formed between corresponding lateral sides on the supporting portions of the two C-shaped side plates and respective protrusion portions respectively, and two sides of the third phenol resin plate are in lap joint with the steps respectively. The fireproof cable bridge has a fireproof effect due to the fact that the phenol resin plates have good heat isolation and fireproof performances.
