The environment-friendly color steel sandwich panel disclosed by the invention has the advantages that the scratch-resistant performance of the color steel plate is increased, so that the service life of the color steel sandwich panel is integrally prolonged; in the meantime, the fireproof performance of the core material is up to non-combustible grade A and the compression strength of the core material is higher than that of rock wool and glass wool core materials, so that the high-temperature resistant performance and the fireproof performance of the color steel sandwich panel are integrally improved.
Description
Technical field
The present invention relates to a kind of chromatic steel sandwich plate, be specifically related to a kind of environment-friendly type chromatic steel sandwich plate.
Background technology
Chromatic steel sandwich plate is a kind of novel space enclosing structure material that integrates load-bearing, insulation, waterproof, fits up, and can be widely used in different building needs, comprises the multiple building fields such as industrial premises, public building, assembled house, cleaning project.Chromatic steel sandwich plate is take color painted steel strip as plane materiel, self-extinguishing type polystyrene, polyurethane, glass wool, rock wool etc. are core, with heat-curable glue in continuous forming machine through the ultralight building board that pressurizes, is heating and curing, the operation such as deburring, fluting, blanking is composited, thickness is generally at 25-250mm.
Chromatic steel sandwich plate has from heavy and light (for the 1/20-1/30 of concrete roof weight), and intensity is high, and (employing high strength is base material, and its anti-stretch-draw intensity can reach 5600kg/cm
2), thermal insulation (its thermal conductivity value is 0.034W/mk), the fast (wet-less operation of speed of application, do not do secondary decoration, construction period can shorten more than 40%), the characteristics of (need not incrustation, the colored zinc plated steel anticorrosive coat keeps the phase at 15-20) bright in colour.Chromatic steel sandwich plate is except being applied to above-mentioned building field, and people also give full play to its characteristics, applies it to more wide field, such as the internal partition wall of steamer, freezer, express highway sound-proof wall etc.
Existing chromatic steel sandwich plate kind comprises:
(1) polystyrene foam plastics sandwiched plate
The polystyrene foam plastics sandwiched plate is as surface layer take color steel sheet, take the flame retardant polystyrene foam plate as core, with dual-component polyurethane as adhesive material, be combined into through the laser heating pressurization, the sandwiched plate that the scale synchronous cutting forms, it is composited by 5 layer materials, i.e. color steel sheet-polyurethane adhesive-polystyrol plastic foam plate-polyurethane adhesive-color steel sheet.
(2) polyurethane foam plastics sandwiched plate
The polyurethane foam plastics sandwiched plate is as surface layer take color steel sheet, take flame-retardant polyurethane foam plastic as core, utilize continuous forming machine, after to the color steel sheet die mould in the middle of two plates spray polyurethane, through sealing pressing colored steel and viscoelastic polyurethane are formed composite board, i.e. polyurethane laminboard.
(3) rockwool sandwich board
Rockwool sandwich board is to make surface layer with color steel sheet, take the non-combustible materials rock wool as core, is adhesive material with two-component polyurethane adhesive, through laser heating pressurization composite molding, the sandwiched plate that the scale synchronous cutting forms.
(4) glass wool sandwiched plate
The glass wool sandwiched plate is to adopt natural crystal such as quartz sand, dolomite, alabaster etc. to be primary raw material, be equipped with other and be melting into glass such as industrial chemicals such as soda ash, boric acid, under molten condition, draw, blow or get rid of into superfine fibrous material by external force, the sheet material of forming with phenolic resin glue.
At present in the sandwich material of chromatic steel sandwich plate commonly used, only having rock wool, glass wool is incombustible material, the use of other sandwich material in chromatic steel sandwich plate very easily causes the generation of fire, and the globality of rock wool, glass wool is poor, compressive strength is low, generally can only be used as wallboard, be not used as the ceiling material.
In addition, in the color painted steel strip coating that uses at present, polyvinylidene fluoride (PVDF) fluorocarbon coating is owing to use polymer with fluorine element as film-forming resin in its coating, make it have excellent anti-atmospheric exposure, anti-solvent, corrosion-resistant, anti-contamination and good processing characteristics and become king in the chromatic board coating, be widely used in top-grade building exterior wall and roofing.Yet there is an obvious weakness in the PVDF colored steel, and namely softer (its pencil hardness＜F), cause the scratch resistant performance in process bad is easy to be scratched in transportation and forming process organic coating.
Summary of the invention
In view of this, the invention provides a kind of environment-friendly type chromatic steel sandwich plate, its core can reach and not fire the A level, compressive strength is high, and the scratch resistant performance of color steel sheet face coat is excellent, thus whole application life of improving chromatic steel sandwich plate.
Environment-friendly type chromatic steel sandwich plate of the present invention, this chromatic steel sandwich plate comprises the outer and heat insulation core material internal layer of color steel sheet, the face coat of described color steel sheet is modified polyvinylidene fluoride fluorocarbon coating and supporting primer coating, and described heat insulation core material is that inorfil, aglite and inorganic chemistry auxiliary agent are the core of raw material preparation.
Further, the component of described modified polyvinylidene fluoride fluorocarbon coating and mass percent thereof are: polyvinylidene fluoride fluorocarbon coating 60%, damage resistant additive 20%, antiager 20%.
Further, described supporting priming paint is epoxy coating priming paint.
Further, the base material of described color steel sheet is hot-dip galvanizing sheet steel or hot-dip coating aluminium-zinc alloy steel plate.
Further, the thickness of described color steel sheet is 0.3 ~ 0.5mm.
Beneficial effect of the present invention is:
1) the present invention adopts modified polyvinylidene fluoride fluorocarbon coating and supporting priming paint as the face coat of color steel sheet, owing to added damage resistant additive and aging agent in the modified polyvinylidene fluoride fluorocarbon coating, therefore anti-atmospheric exposure, solvent resistance, weatherability, the corrosion resistance of color steel sheet have been improved, particularly improved the scratch resistant performance of color steel sheet, thus whole application life of having improved chromatic steel sandwich plate;
2) to adopt inorfil, aglite and inorganic chemistry auxiliary agent be the core of raw material preparation in the present invention, its fiber dispersion evenly and each other has key to connect or absorption and the core that forms porous and have certain bulk strength, this core fireproof performance reaches does not fire the A level, and compressive strength is higher than the core of rock wool and glass wool, Integral lifting the high temperature resistant and fireproof performance of chromatic steel sandwich plate.
