A multipurpose composite wallboard panel is disclosed as having an aluminum sheet (14) attached by means of an adhesive (16) to a wallboard panel (12), such as a gypsum wallboard panel. Such a composite panel can readily be handled and quickly attached to the framework of buildings for the purpose of bracing, finishing, fireproofing, and thermally insulating wall structures in a single wall sheathing procedure.

The invention relates to an expansion type fire-retardant coating which contains organic silicon resin, and particularly comprises the components in part by weight: 10-40 parts of resin, 10-40 parts of catalyst, 5-20 parts of charcoal forming agent, 5-20 parts of foaming agent, and 3-15 parts of flame retardant, wherein the resin is selected from one or more of epoxy resin, phenolic resin, and acrylic resin as well as organic silicon resin. According to the invention, the shortcoming that the traditional fire-retardant coating is poor in heat stability is overcome; the coating has the characteristics of good fireproofing heat-insulating property, good bonding force, high strength, capability of bearing high and low-temperature circulation influence, excellent water resistance, acid resistance and salt corrosion resistance of coating layer, difficult in falling, stability in storage, good decoration property, convenience for construction and the like; during combustion, no smog or little smog is generated; and the coating is particularly suitable to be used as a fire-resistant coating for ultra-thin steel structures, veneer type fire-retardant coating and cable fire-retardant coating.

A fire protection apparatus for an oil cooler in an aircraft auxiliary power unit compartment adapted to at least partially cover the oil cooler to thereby at least partially block flames from directly impinging the oil cooler in the event of a fire in the compartment. An associated means and method are also disclosed.

The invention relates to an environmentally-friendly, energy-saving and fireproofing lightweight roof panel, floor plate or wallboard, which comprises an upper surface layer, a lower surface layer and frame ribs. Insulating layers are arranged between the upper surface layer and the lower surface layer, and are cement polymer foamed plastic powder lightweight insulating plates or are formed by compounding the cement polymer foamed plastic powder lightweight insulating plates and any one of molded polystyrene foam plates, extruding-molded polystyrene foam plates and rock-wool slabs respectively; fiberglass alkaline-resistant mesh fabric is arranged in the upper surface layer and the lower surface layer; the frame ribs are fixedly connected to the lower surface layer; and an anticorrosion steel reinforcement frame is arranged in the frame ribs. In the environmentally-friendly, energy-saving and fireproofing lightweight roof panel, floor plate or wallboard of the invention, the lightweight insulating plates and lightweight surface layer mortar are manufactured by foamed plastic powder; the foamed plastic powder and heat-preservation foamed plastic form particles are applied to lightweight concrete; and materials for the upper and lower surface layers and the frame ribs are enhanced by two or more assorted fibers so as to fulfill the aims of lightweight, high strength, energy saving, sound insulation, fireproofing, crack resistance and durability.

The invention discloses a homogeneous material-containing corundum-mullite high-strength abrasion-resisting plastic, belonging to the field of high-temperature abrasion-resisting fireproofing material, comprising high-aluminum homogeneous material, alumina fine powder, silica fine powder, clay, phosphoric acid, aluminum dihydrogen phosphate solution, pure calcium aluminate cement and the like as raw materials, wherein the homogeneous material is as follows: the content of Al2O3 is 70-90% and the volume density is 2.9-3.5g.cm<-3>. Synthetic homogeneous material with low water-absorption, low porosity and high homogeneity is used for substituting the traditional natural raw material of sintered alumina clinker with high-absorption, high porosity and low homogeneity or composite raw material system of corundum and mullite to produce homogeneous corundum-mullite high-strength abrasion-resisting plastic. Distinguished from the castable, the plastic can be directly utilized in the construction method of smearing and ramming without supporting a module. The material of the invention is good in workability, high in strength, good in abrasive resistance and optimal in on-site usage effect, which is in favour of prolonging service life of furnace lining and improving utilization efficiency of the high-temperature furnace.

The invention discloses a building strengthening method, which comprises the following steps of: 1) clearing the surface of a structure to be strengthened to expose a hard part; 2) carrying out water spray wetting on the structure to be strengthened; 3) implanting pins connecting a reinforcing steel bar net and the structure to be strengthened, and bonding the reinforcing steel bar net; 4) spraying an interface agent coating on the surface of the structure to be strengthened; and 5) spraying a polymer modified cement mortar bond layer and a polymer modified cement mortar protective layer by layers on the interface agent coating. The method can effectively improve the bearing capacity of the structure to be strengthened, improves the rigidity of the structure to be strengthened, and has less occupied space; a molded surface strengthening structure and the structure to be strengthened have the advantages of reliable bond, compactness, no crack, waterproofing, permeability resistance, fireproofing, high-temperature resistance, Cl-corrosion resistance, carbonization prevention, rust resistance and good durability; and a construction process is simple, formworks are not needed to be built, the speed of improving the strength of polymer modified cement mortar is high, and a construction period is greatly shortened. The method can be simultaneously applied to repairing and strengthening of the existing concrete structures and masonry structures, and solves the problems of breakage and aging of materials and insufficient structural strength of an old building.

The invention relates to a bi-component polysulfide fireproofing flame retardant sealant and a preparation method thereof, wherein the bi-component polysulfide fireproofing flame retardant sealant is prepared from the following components according to parts by weight: component A: 50-100 parts of liquid polysulfide rubber, 30-70 parts of flame retardant plasticizer, 50-150 parts of flame retardant filler, 60-200 parts of calcium carbonate, 0.3-1.2 parts of main agent micro-molecular finishing agent and 0.5-1.5 parts of silane coupling agent; component B: 10-30 parts of manganese dioxide, 20-60 parts of plasticizer, 1-3 parts of semi-strengthening agent carbon black and 0.4-1.5 parts of accelerant.
