The invention belongs to the field of tunnel fireproof doors, and particularly discloses a composite tunnel fireproof door, a fireproof door system and a preparation method. The composite tunnel fireproof door is of a three-layer composite structure composed in the mode that a fireproof layer is sandwiched between two composite surface layers. The fireproof layer is made of a fireproof heat-resistant material, and the composite surface layers are made of high-strength corrosion-resistant materials. The fireproof door system comprises a door frame and the fireproof door mounted in the door frame, and the fireproof door is mounted in a tunnel doorway through the door frame. The preparation method comprises the steps that the fireproof layer is prepared, and a resin solution is prepared; theresin solution is smeared on the two surfaces of the fireproof layer to prepare fireproof layer prepreg; glass fibers are soaked in the resin solution and then dried to prepare prepreg; the prepreg issuperimposed on the two surfaces of the fireproof layer prepreg and then preheated and subjected to heat preservation to obtain a raw material plate; and the raw material plate is hot-pressed to prepare the composite tunnel fireproof door. The requirements of explosion resistance, wind pressure resistance, fatigue resistance and corrosion resistance are met while the fireproof performance is achieved.

The invention discloses a high-flame-retardance fireproof cable made of inorganic materials. The high-flame-retardance fireproof cable comprises a plurality of wire cables, a fire-resistant layer made of inorganic materials and a flame-retardant jacket. The fire-resistant layer made of the inorganic materials is extruded on the wire cables; the flame-retardant jacket is sleeved on the fire-resistant layer made of the inorganic materials; each wire cable consists of a copper conductor and a vitrified silicon rubber insulating layer extruded on the copper conductor; and a filling layer is filled in the fire-resistant layer made of the inorganic materials. The high-flame-retardance fireproof cable is characterized in that the fire-resistant layer made of the inorganic materials comprises, by weight, 85% of magnesium hydroxide, 6% of serpentine powder, 4% of magnesium calcium carbonate, 3% of sodium silicate and 2% of chlorinated paraffin which are squeezed to form the fire-resistant layer made of the inorganic materials. The insulating layer is made of vitrified silicon rubber, and because the insulating layer has high fire resistance and the vitrified silicon rubber is vitrified at a high temperature, the insulating performance of the cable is guaranteed during spontaneous combustion of the cable and external fire disasters. Besides, as the fire-resistant layer made of the inorganic materials is totally made of the inorganic materials by cold stirring and extruding, the materials cannot be combusted during the fire disasters, and flame-retardant and fireproofing effects can be achieved effectively.

A preparation method for a laminated structure of a photovoltaic assembly, the laminated structure and the photovoltaic assembly, which are prepared by using a lamination process. The lamination process comprises a first heating stage, a second heating stage, and a third pressurization and cooling stage. In the first stage, the heating temperature range is from 110ºC to 130ºC, and the heating time range is from 100 seconds to 600 seconds; in the second stage, the hating temperature range is from 131ºC to 200ºC, and the heating time range is from 100 seconds to 1200 seconds; and in the third stage, the cooling temperature range is from 25ºC to 60ºC, and the pressurization range is from 0.05 Mpa to 0.25 Mpa. The lamination process is implemented in a low-temperature environment, power consumption is reduced, and the flatness of the laminated structure of the photovoltaic assembly is ensured, thereby further facilitating the mounting, enforcement and application of the photovoltaic assembly.
