Colour is L：20—27, a：0±2.0, b：0 ± 2.0, glossiness reaches 2 ± 1.5, surface can anti-IPA solvent wipings up to 30-
50；Aluminium foil, be bonded, aluminum foil thickness 0.007mm by S3 with the ultralow adhesion Organic silicon protective film of high stable type, is highlighted
Light reflectance >=90% in face, is bonded with equally very thin delustred coating black polyamide thin film, by several kinds of examinations
To test, serious fold and lines situation is produced during fitting to be overcome, and therefore, aluminium foil is bonded by we with protective film,
Overcome fold using protective film to increase the deflection of aluminium foil, using polyester film as base material, one side coating has the Organic silicon protective film
Machine silicon adhesive, is coated with the one side fitting aluminium foil of organosilicon adhesive, when aluminium foil is bonded with protective film, to overcome pleat
Protective film is positioned over head machine dispensing shaft to wrinkle problem by us, and protective film combs that extend can be smooth by roller, then with being positioned over
Aluminium foil at machine tail blowing is bonded, and aluminium foil is metal, and material endures with all one's will tensionless winkler foundation and easy fold pressure wound, in processing procedure
It is not easy by excessive roller and long distance, therefore the dispensing shaft being positioned over before coating tail stainless steel laminating wheel is adapted to the most,
The distance of dispensing shaft and stainless steel laminating wheel sets 1m, both positions be it is parallel be optimal；
S4, the black polyamide thin film of step S2 coating delustred coatings is bonded with step S3 the aluminium foil of Organic silicon protective film into
Row fitting, is positioned over machine coating head, coating fire retardant glue forms composite flame-proof gluing by delustred coating black polyamide thin film
Layer, process of passing through tunnel baking oven are built bridge after curing, then are bonded with the aluminium foil with protective film, and composite flame-proof adhesive layer is glutinous with height
Based on acryl adhesive, adhesive viscosity is 5000 ± 1000CPS, and solid content is 40 ± 2%, adhesion 1kg/25mm, is hindered
It is 4% to fire liquid adding proportion, is added after being diluted with toluene in acryl adhesive, is stirred and mixes fire retardant glue,
The coating solid content of fire retardant glue is 30%, and coated glue layer thickness is 0.015mm~0.02mm, and manufacturing machine speed is 25m/Min, tunnel
100 DEG C of oven temperature highest setting, the adhesion of adhesive layer is 600g/25mm；
S5, tear off ultralow adhesion Organic silicon protective film, and the compound good materials of step S4 are first sent into 10 DEG C of cryogenic box and are put
24hrs is put, the position of upper compounding machine dispensing shaft after material is taken out, stripping winding is carried out with machine speed 12m/Min.
