Description
Technical field
The present invention relates to a kind of composite board and production method, specifically a kind of new mineral fibres and aluminium base
Alloy composite board and production method, are particularly well-suited to high intensity, low-gravity, antioxidation, the automobile-used sheet material of low cost and other
Field.
Background technology
At present, civil motor vehicles loss of weight energy-conservation is trend of the times；According to statistics, 100 kilograms of the every loss of weight of vehicle, it is possible to decrease energy
Consumption 5%-7%, the motor vehicles loss of weight means that normal domestic is low and middle-grade times are to reduce steel plate thickness, but the direct result brought is
Vehicle collision safety coefficient substantially reduces；The loss of weight means of high-end vehicle are to use carbon fiber and aluminum alloy materials in a large number, become
This is high.
In other industry and civil area, based on metal and nonmetal plate, material is widely applied, black metal sheet
Material (as steel plate) price low-intensity is higher but ratio is great, non-ferrous metal plate (as acieral) light specific gravity but intensity is slightly weak and valency
Lattice are high；Nonmetal plate (as plastics) etc. is mostly organic material, inflammable easily aging, limits it and uses approach.
Mineral fibres has high intensity (tensile strength is 6 times of steel), high abrasion, low-gravity (0.2-0.7g/cm3), former
Material is easy to get, the advantage such as with low cost, and early in the eighties in last century, mineral fibres has originally been mixed making by day with acieral
Internal combustion engine, service life is 1/3rd that more than ten times of conventional piston and proportion are only conventional piston, domestic at present
There are relevant manufacturers in production, but due to complex manufacturing technology, relatively costly, therefore be only limited to the special dimensions such as piston and use, class
Mineral fibres like sheet material class be there is no on a large scale using pertinent literature with acieral composite.
China is a bauxite resource big country, and metallic aluminium production capacity is seriously superfluous；China is also iron and steel production capacity big country simultaneously, but ferrum
Ore resource is deficient, the especially long-term dependence on import of some special rolling-mill sections (as automobile-used sheet material), limits industry development.
Content of the invention
Present invention aims to the problems referred to above, a kind of high intensity (tensile strength 250-650Mpa), low ratio are proposed
Weight (1.2-2.7g/cm3), the New Mineral fiber of (close with ordinary carbon steel sheet material) with low cost and acieral composite board
And production method.
For realizing object above, this invention takes following technical scheme：A kind of new mineral fibres is closed with aluminium base
Golden composite board and production method, described composite board composition composition includes the mineral fibres of 10-70% (part by weight),
The acieral of 10-70% (part by weight), described acieral prioritizing selection alumin(i)um zinc alloy and almag；Described is compound
Sheet material chats fibres with the composition form of acieral are：The mineral fibres blanket of crisscross, uniform overlap joint or paper, with aluminium base
Aluminium alloy permeates, and after cooling extruding, acieral tight lives every mineral fibres the gap being filled between mineral fibres,
Play the cementation of mineral fibres；And mineral fibres low-gravity (0.2-0.7g/cm3), high intensity, low cost characteristic advantage
It is present in composite board, has dragged down sheet material proportion, reduce board cost, and crisscross mineral fibres is just as closing
No several reinforcements are added, as the principle of armored concrete, concrete likened to by acieral, and mineral are fine in golden plate
Dimension likens reinforcing bar to, coordinates the bond stress to mineral fibres for the acieral, forms a kind of light-high-strength mineral fibres and aluminium base
Alloy composite board.
Described a kind of new mineral fibres and the production method of acieral composite board, production equipment is included at heat
Reason continuous tunnel furnace, acieral liquid pool, aluminium alloy heat components and parts, will bring liquid pool under mineral fibres blanket or paper guard mode
Upper and lower transmission with holes is entrusted, filter pressing roller group, thickness adjusted roller group and trimming, wrap-up.
The effect of described heat treatment tunnel furnace is heating mineral fibres blanket or paper, to eliminate fiber inherent strain, weight
New sort lattice structure is so as to be easier to combine closely with aluminum-based alloy liquid.
Described acieral liquid pool is lower bands heater, outside is covered with the container of insulation material, and its effect is：Heat
The mineral fibres blanket processing or paper enter acieral liquid pool and soak, and fully absorb aluminum-based alloy liquid, combine to form composite wood
Material, and then extrude formation composite board with each roller group；Constantly enter with mineral fibres, absorb aluminium alloy, need at any time
The aluminium alloy consuming is supplemented into acieral liquid pool.
The flexible metal band or wire netting for smooth surface, densely covered open-work is entrusted in described transmission upper and lower with holes, due to
Aluminum-based alloy liquid density is big, buoyancy big, and mineral fibrous material density is little, affects normal for avoiding it to float in aluminium alloy
Produce, entrusted using upper and lower transmission with holes and clip mineral fibres and move ahead, densely covered open-work is in order that aluminum-based alloy liquid passes through thoroughly
Mineral fibrous material is permeated in hole.
To roller, pressure adjustable section, its effect is to squeeze out just to the power that described filter pressing roller group operates for constant speed opposite direction
Just absorb the composite board of aluminum-based alloy liquid, now aluminium alloy not yet cools down, also in liquid, squeezing by filter pressing roller group
Pressure, unnecessary aluminium alloy is squeezed out return acieral liquid pool, reduces non-ferrous metal consumption.
To roller, pressure adjustable section, its effect is extruding to the power that described thickness adjusted roller group operates for constant speed opposite direction
Not yet cooling composite board, improves its degree of compaction to increase intensity, and reaches required thickness by extruding.
Advantage of the invention is that：By cheap, light weight, the mineral fibres blanket of high intensity or fibrous paper, higher with price
Acieral combines, and by the mode of production of science, produces the light-high-strength ore deposit that with low cost, proportion is little, intensity is high
Fibres and acieral composite board, provide clothes for the energy-saving and emission-reduction of related supporting industry, reduces cost, digestion superfluous production capacity
Business.
