Description
Technical field
The invention belongs to structural lumber technical field, and in particular to a kind of insulated fire coloured silk steel clamp of mixed straw foaming
Core corner board and its manufacture craft.
Background technology
China is a large agricultural country, agricultural straw resource very abundant, produces about 700,000,000 tons of stalk per year, occupies first place in the world.
In recent years, as China's rapid economic development, rural energy structure are traditional using straw as life there occurs significant change
The demand of fuel is reduced year by year, causes the remaining accumulation of most straws.Stalk fibre is as a kind of native cellulose fibre, tool
There is good biodegradability, environmentally friendly product can be turned into.These resources do not obtain good profit not only at present
With, and our every summer and autumn, the incineration flue gas with regard to field can be seen.Live and work of these flue gases to people
Make troubles, greatly influence our living environment, waste a large amount of renewable resources.
On the other hand, chromatic steel sandwich plate is a kind of to integrate load-bearing, insulation, waterproof, the new building enclosure material fitted up
Material, can be widely applied to different building needs, including industrial premises, public building, assembled house, cleaning project etc. are a variety of builds
Build field.For chromatic steel sandwich plate using color painted steel strip as plane materiel, self-extinguishing type polystyrene, polyurethane, mineral wool, rock wool etc. are core
Material, with heat-curable glue in continuous forming machine it is pressurized, be heating and curing, deburring, fluting, the process such as blanking be combined it is ultralight
Building board, thickness is typically in 25-250mm.
Chromatic steel sandwich plate has from heavy and light (for the 1/20-1/30 of concrete roof weight), intensity it is high (use high intensity for
Base material, its anti-tensile tensile strength is up to 5600kg/cm2), insulation (its thermal conductivity value is 0.034W/mk), speed of application is fast
(wet-less operation, does not do secondary decoration, and construction period can shorten more than 40%), lovely luster is (without incrustation, coloring zinc
Steel plate anticorrosive coat is kept for the phase in 15-20) the characteristics of.For chromatic steel sandwich plate in addition to applied to above-mentioned building field, people are also abundant
Its feature is played, applies it to broader field, internal partition wall, freezer, the express highway sound-proof wall of such as steamer.
Existing chromatic steel sandwich plate species includes：
(1) polystyrene foam plastics battenboard
Polystyrene foam plastics battenboard be using color steel sheet as surface layer, using flame retardant polystyrene foam plate as core,
By the use of dual-component polyurethane as cementing agent, it is combined into through laser heating pressurization, the battenboard that scale synchronous cutting forms, it is by 5
Layer material is combined, i.e. color steel sheet-polyurethane adhesive-polystyrol plastic foam plate-polyurethane adhesive-color steel sheet.
(2) polyurethane foam plastics battenboard
Polyurethane foam plastics battenboard be using color steel sheet as surface layer, using flame-retardant polyurethane foam plastic as core, profit
With continuous forming machine, (polyurethane foam is usually with A material and B to spray polyurethane among two plates after to color steel sheet die mould
Material in high-pressure bottle send out mixed foaming produce, A material be usually combined polyether or other, B material be generally isocyanates or its
It), colored steel and viscoelastic polyurethane are formed composite board, i.e. polyurethane laminboard by sealed pressurization.
(3) rockwool sandwich board
Rockwool sandwich board is to make surface layer with color steel sheet, using non-combustible materials rock wool as core, uses two-component polyurethane adhesive
For cementing agent, through laser heating pressurization composite molding, the battenboard that scale synchronous cutting forms.
(4) mineral wool battenboard
Mineral wool battenboard is to use natural crystal such as quartz sand, dolomite, alabaster etc. as primary raw material, be equipped with it is other such as
The industrial chemicals such as soda ash, boric acid are melting into glass, draw, blow or get rid of into superfine threadiness by external force in the molten state
Material, the sheet material being cemented to phenolic resin.
In the sandwich material of currently used chromatic steel sandwich plate, only rock wool, mineral wool are incombustible materials, other sandwiches
Use of the material in chromatic steel sandwich plate easily causes the generation of fire, and rock wool, the globality poor of mineral wool, compressive strength
It is low, it can only typically be used as wallboard, be not used as ceiling materials.
In addition, in the color painted steel strip coating used at present, polyvinylidene fluoride (PVDF) fluorocarbon coating due to
The polymer with fluorine element is used in its coating as film-forming resin, makes it have excellent resistance to atmospheric exposure, solvent resistant, resistance to
Burn into dirt-resistant and good processing characteristics and as the king in chromatic board coating, be widely used in top-grade building exterior wall
And roofing.
Any of the above chromatic steel sandwich plate suffers from common technical problem：
(1) chromatic steel sandwich plate is when being assembled into house, the bad solution of turning problem, and existing riveting is wasted time and energy, and not
Firmly；
(2) battenboard is typically all the small soft material of density, and occupancy volume is larger, and cost of transportation is higher；
(3) chromatic steel sandwich plate turning is that ectonexine is all after separating production, in conjunction with into chromatic steel sandwich plate turning, a lot
Sandwich material is just applied to chromatic steel sandwich plate after often producing some time, and ectonexine will also carry out specially treated ability when combining
Enough compactnesses for ensureing to combine, and if the sandwich material production time it is long, it is easy to aging, so as to influence whole color steel clamp
The service life at core plate turning.
Chinese patent publication No.：CN2777326, publication date：2006.05.03 patent document disclose a kind of color steel
Airduct flange connecting apparatus, including groove profile flange profile, the turning of two vertical flange profiles is connected, cast with flange profile
The barb being integrated, the card article of clamping is coordinated with two flange barbs, and described two interfaces in turning are to be cast as with the turning
The clamp being integrated；The groove profile flange profile groove inner end is conformed with.The utility model can depart from bonding machine with it is various
The section bar of different length is arbitrarily made with various sizes of flange connecting apparatus, makes work progress more convenient and flexible.The practicality
It is new to solve the connectivity problem at turning by flange connecting apparatus and groove profile flange profile, but suitable for the coloured steel sheet air pipe of individual layer
Structure, can not solve the problems, such as turning for the battenboard of bilayer.
The content of the invention
1. technical problems to be solved
For rural area straw in the prior art insecure, separated production is connected using insufficient, chromatic steel sandwich plate corner part
The problem of causing to need specially treated when combining and influence whole sheet material service life, the invention provides a kind of mixed straw
The insulated fire coloured silk steel clamp core corner board and its manufacture craft of foaming.It by special making structure, can separate transport and energy
Enough production immediately, realizes and reduces cost of transportation, ectonexine is tightly combined and improves service life, being capable of insulated fire, color steel
The purpose of battenboard corner part is connected firmly, and rural area straw is also fully utilized.
2. technical scheme
