Description
Technical field
The utility model relates to the production field of insulation pipe, relates to a kind of ultralight high strength ventilating and thermal insulating pipeline specifically.
Background technique
The upper conventional ventilation themral insulation pipe of existing motion carrier (as high ferro, track traffic, aerospace vehicle) uses glass wool and epoxy resin composite structure.Utilize heat pressing process successively alternately by 4 layers of glass wool and 4 layers of epoxy resin compound finally shaping, complex process and process cycle is long.Above-mentioned insulating structure is because by raw material, the impact of structure and processing technology factor, easily causes the tube wall of finished product, caliber low precision, finished weight weight, intensity is low, above-mentioned insulating structure is used on motion carrier and not only wastes energy, and easily brings potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and reasonable, processing and convenient for production, has lightweight, insulation, fire prevention and resistance to high temperature.
The purpose of this utility model is achieved in that this insulation pipe comprises interior cured layer from inside to outside successively, the first honeycomb thermal insulation layer be compounded on interior cured layer, the middle cured layer be compounded on the first honeycomb thermal insulation layer, the second honeycomb thermal insulation layer be compounded on middle cured layer, the outer cured layer be compounded on the second honeycomb thermal insulation layer.
Described interior cured layer, middle cured layer and outer cured layer adopt cyanamide esters resin or carbon-fiber cloth to make.
Described first honeycomb thermal insulation layer and the second honeycomb thermal insulation layer adopt aramid fiber cellular material to make.
Described insulation pipe structure can be different according to service condition, make different pipe thickness, different rigidity intensity, different according to transport agent in pipeline, can select different interior cured layers.
Described cyanamide esters resin has excellent mechanical behavior under high temperature, and flexural strength and tensile strength are all high than difunctional epoxy resin; Extremely low water absorption rate (<1.5%); Molding shrinkage is low, good stability of the dimension; Good heat resistance, vitrification point is at 240 ~ 260 DEG C, and most high energy reaches 400 DEG C, modified can 170 DEG C of solidifications; Humidity resistance, flame retarding, cohesiveencess are all fine, and the adhesive property of the reinforcing material such as glass, carbon fibre, quartz fibre, whisker is good; Excellent electrical property, has extremely low permittivity (2.8 ~ 3.2) and dielectric loss angle tangent value (0.002 ~ 0.008), and the change of fire retardant to temperature and wave frequency all shows distinctive stability (namely having wide band).Cyanamide esters resin can be used for the structural member making military affairs, Aeronautics and Astronautics, navigational field, such as wing, ship shell etc., also can be made into foam sandwich construction material conventional in aerospace, cyanamide esters resin has good compatibility, heat resistance and the mechanical property of material can be improved with the copolymerization such as epoxy resin, unsaturated polyester, also can be used to, to other resin modified, be used as adhesive, coating, syntactic foam, artificial dielectric material etc.
Described aramid fiber cellular composite material is the structure be made up of multiple hexagonal cells, the favous cross section of outer appearnce, 90% to 99% of cellular material is empty, and aramid fiber honeycomb core and upper and lower cyanamide esters resin or carbon-fiber cloth close adhesion compound just form core plate structure.Feature after compound: quality is one of conventional thermal insulation pipe about five parts weight only, and aramid fiber honeycomb has good heat insulating ability, substitutes conventional glass completely, and intensity after compound, rigidity is large.(can significantly improve flexural rigidity and the intensity of material under equivalent weight condition, rigidity can improve 37 times, and intensity can improve 9 times).Because of its lightweight of aramid fiber honeycomb, the characteristic of high strength, is widely used in track traffic, Aero-Space, and other motion carriers.Under given density, aramid fiber honeycomb is better than other materials in conjunction with the impact resistance of structure after carbon fiber prepreg or cyanamide esters resin compound.
Described carbon-fiber cloth, by materials such as carbon fiber yarn, epoxy resin, release paper, is called carbon fiber prepreg through film, hot pressing, cooling, overlay film, the composite material that the processes such as to batch, has another name called carbon fibre initial rinse fabric.Why make prepreg cloth be because this is the preliminary impregnation of resin and carbon fiber, be only the cause of final impregnation when formed product.Carbon fiber is compared with traditional glass fibre, and Young's modulus is that they are more than 3 times; It is compared with Kafra fiber, and Young's modulus is its about 2 times, insoluble not swollen in organic solvent, acid, alkali, and corrosion resistance is given prominence to.
Described vacuum bag complex technique, according to wanting the shape making pipeline to make mould, each Rotating fields of hand lay-up, puts into vacuum bag, is evacuated to the fixed time, and this technology is vacuum bag complex technique.
Described hot-forming complex technique, by mould, lay complete by each Rotating fields, and lay release paper, by specified pressure, temperature, fast shaping, and slow cooling, this forming technique is hot-forming complex technique.
Adopt the comb core that overstretching technology is made, its tangent plane is shaped to approximate rectangular, and the bendable curvature of its transverse direction is very good, and simultaneously longitudinal intensity is very large, can according to different shaping needed for pipeline, as circle, square etc., Appropriate application small space.
The utility model has the following advantages and good effect:
1, its number of plies of insulation pipe structure described in the utility model can use desirable strength by reality, the changes such as fire-proof high-temperature resistant grade.
2, the utility model composite curing layer selects cyanamide esters resin, the prepreg such as carbon-fiber cloth, can realize good flame retardant property, can accomplish very high strength with the compound of core simultaneously.Keriotheca raw material is aramid paper honeycomb, and outer composite curing layer the selection of material also can adopt cyanamide esters resin except carbon-fiber cloth, to reach the different requirements of different application occasion to tube performance.
3, the pipeline of the utility model structure can have the lightweight of aramid fiber honeycomb, thermal insulation property, utilize again cyanamide esters resin, obtain and epoxy resin similarity surface, there is again the fire prevention similar to phenol and resistance to high temperature simultaneously, greatly reduce the weight of pipeline, improve intensity and the thermal insulation property of pipeline, this structure is not limited to tubular shape.
