It has been widely applied in sky, space flight, automobile, machine-building, ship and chemical industry.Aluminum alloy doors and windows are referred to and are squeezed using aluminium alloy
Die mould material be frame, stile, fan material production door and window be known as aluminum alloy doors and windows, abbreviation aluminium door and window.
Aluminum alloy doors and windows surface is needed using suitable coating material, to increase corrosion resistance, the washing of aluminum alloy doors and windows
The functions such as property, fire-proof and thermal-insulation, the coating of some aluminum alloy doors and windows to improve its using effect as needed, but on the market
The fire-proof and thermal-insulation effect of material is general.
Utility model content
Aluminum alloy surface is used for good heat-proof quality in view of this, the purpose of this utility model is to provide a kind of
Composite coating.
In order to achieve the above objectives, the technical solution of the utility model is:
A kind of composite coating for aluminum alloy surface, including priming coat, the hollow ceramic microspheres being successively combined with each other
Powder coating, raw lacquer emulsion layer, fine silicon dioxide airsetting gel coating and finishing coat, the priming coat are compound in aluminum alloy base material
On surface.
Further, the priming coat is fluorine-containing epoxy resin layer or polyamide resin layer.
Further, the finishing coat is Acrylic Polyurethane Coating.
Further, the coating layer thickness of the priming coat is 45~55 microns, and the coating layer thickness of the finishing coat is 20
~30 microns.
Further, the coating layer thickness of the hollow ceramic microspheres powder coating and fine silicon dioxide airsetting gel coating
Respectively 50~60 microns.
Further, the coating layer thickness of the raw lacquer emulsion layer is 5~15 microns.
After adopting the above technical scheme, a kind of composite coating for aluminum alloy surface of the utility model, has with following
Beneficial effect: it is simple and reasonable, there is thermally conductive system using the fine silicon dioxide aeroge of fine silicon dioxide airsetting gel coating
Number is small, intensity is high, anticorrosive, can extend the fire prevention time, will not release the substance being harmful to the human body under high temperature, belongs to complete
Green fire prevention material；The excellent weatherability having using the hollow ceramic microspheres of hollow ceramic microspheres powder coating, it is corrosion-resistant
Property, chemical-resistance and thermal insulation, fine silicon dioxide aeroge and hollow ceramic microspheres play the heat-insulated effect that cooperates with, significantly
Promote the fire protecting performance of aluminum alloy materials.
Detailed description of the invention

Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
A kind of composite coating for aluminum alloy surface of the utility model, including be successively combined with each other priming coat 01,
Hollow ceramic microspheres powder coating 02, raw lacquer emulsion layer 03, fine silicon dioxide airsetting gel coating 04 and finishing coat 05, priming coat
01 is compound on the surface of aluminum alloy base material 06.Wherein, the granularity of hollow ceramic microspheres powder is 10~20 microns.Fine dioxy
The granularity of SiClx is not described in detail herein using row particle size range known in the industry.
As a preferred embodiment, priming coat 01 is fluorine-containing epoxy resin layer, the coating layer thickness of epoxy resin layer
It is 50 microns.Using orientation shown in FIG. 1 as reference azimuth, hollow ceramic microspheres powder coating 02 is coated on fluorine-containing epoxy resin layer
On the top surface of (i.e. priming coat 01), the coating layer thickness of hollow ceramic microspheres powder coating 02 is 55 microns；Raw lacquer emulsion layer 03 applies
It is overlying on the top surface of hollow ceramic microspheres powder coating 02, the coating layer thickness of raw lacquer emulsion layer 03 is 5-15 microns, the present embodiment
Specially 8 microns；Fine silicon dioxide airsetting gel coating 04 is coated on the top surface of raw lacquer emulsion layer 03, fine silicon dioxide gas
The coating layer thickness of gel coat 04 is 55 microns；Finishing coat 05 is Acrylic Polyurethane Coating, Acrylic Polyurethane Coating coating
In on the top surface of fine silicon dioxide airsetting gel coating 04, the coating layer thickness of Acrylic Polyurethane Coating is 30 microns.
Compared to the prior art, the utility model has the advantages that since hollow ceramic microspheres powder coating 02 adds
Hollow ceramic microspheres can expand to form thermal insulation layer in baked wheaten cake, delay aluminium alloy to be heated heating rate；Simultaneously using micro-
The fine silicon dioxide aeroge of fine silica airsetting gel coating 04 have thermal coefficient is small, intensity is high, erosion-resisting characteristic,
To extend the time of preventing fires, the substance being harmful to the human body will not be released under high temperature, belongs to full green fire prevention material, and fine
Aerosil is played with hollow ceramic microspheres cooperates with heat-insulated effect, greatly promotes the fire protecting performance of aluminum alloy materials.
The product form and style of above-described embodiment and attached drawing and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
