Color coated steel sheet
Color-coated steel sheets are products made on a continuous unit using cold-rolled steel strips, galvanized steel strips (electro-galvanized, hot-dip galvanized, etc.) as substrates, after surface pretreatment (degreasing, cleaning, chemical treatment, etc.), coating with liquid coating by roller coating, and then baking and cooling. Color-coated steel sheets have the advantages of good corrosion resistance, bright colors, beautiful appearance, easy processing and forming, and the original strength of steel sheets, and low cost.
Types of color-coated substrates for construction
Alu-zinc substrate
Excellent corrosion resistance, suitable for making building exterior panels, can be processed at various levels such as general forming, mechanical biting, etc.
Hot-dip galvanized aluminum-zinc substrate
The coating composition is roughly 55% aluminum, 1.5% silicon, and the rest is zinc. This substrate has excellent corrosion resistance and is suitable for making building exterior panels. It can be processed at various levels such as general forming, stamping, and deep stamping.
Hot-dip galvanized aluminum substrate
The coating composition is 5% aluminum, 0.1% mixed rare earth elements, and the rest is zinc. The substrate has excellent corrosion resistance, good plating forming properties, and good coating and welding properties.
Electroplated zinc substrate
The coating has high purity, good corrosion resistance, thin zinc layer, and good processing performance. It is suitable for making home appliances, steel windows or indoor partitions, etc.
Types of coatings
Primer
Primers are divided into polyester primers, polyurethane primers, epoxy primers, etc. according to different film-forming resins. Commonly used are epoxy primers and polyurethane primers, which are processed and manufactured with anti-rust pigments such as zinc chrome yellow and strontium chrome yellow.
Topcoat
Generally, polyester resin (PE), high-durability polyester resin (HDP),
silicon-modified polyester resin (SMP), polyvinylidene fluoride resin (PVDF), acrylic resin, polyurethane are used. Thermosetting cross-linking curing system uses methyl ether amino resin or blocked isocyanate resin, and pigments with good high temperature resistance and weather resistance are selected.
Backcoat
Currently, it can be divided into 2/1, 2/2, and 2/1M systems in China.
2/1 system: The back can be coated with a layer of primer or only a layer of back paint. It is mainly used for sandwich panels and requires the coating to have good bonding and foaming properties.
2/2 system: A two-coat system of primer and back paint is used. Foaming properties are generally not required. It is used as a single board.
2/1M system: Generally, 3 microns of primer and 6 microns of back paint are applied. It can replace 2/1 and requires the back to be able to foam.
Introduction to PIR
PIR(Polyisoeyanurate Foam)is the abbreviation of polyurethane modified isocyanurate foam, which is a kind of Foam with typical carbon and nitrogen hexagonal rigid heterocyclic structure.
PIR is an ideal organic low temperature heatinsulation material with low thermal conductivity,light weight and strong adaptability,which is widely used in the fieldof thermal insulation in cold storage, construction,oil refinery,chemical plant.

Characteristics of polyurethane modified isocyanurate foam
Good resistance tolow temperature and heat
PIR foam can be used at-196℃~+160℃ for a long time,and can withstand temperatureup to 200℃ in a short timewith the size change rate<1%.
Good flame penetration resistance
The thickness of 2.5cm PIR foam board can be burmed through by propane flame for 30min,while the same thickness of polyurethane sheet will be bumed through with a few minutes.
Low smoke when burning,good flame-retardant performance
Compared with polyurethane foam, polyurethane modified isocyanate foam has better ignition resistance, flame spread resistance and burnout resistance.When burning,a solid carbonized surface with less smoke will be formed quickly.
Low water absorption
PIR foam has higher closed cell rate and lower water absorption than polyurethane foam.
High stability
Due to the different molecular structures, PIR foam contains more polyisocyanurate chains, which are more stable to heat and most chemical reagents. And the isocyanurate chains have excellent temperature resistance and dimensional stability.
