The content of gas, so as to slow down reaction speed, also just extends the working life of the coating；N-butanol is the good molten of polyurethane
Agent, polyurethane can be wrapped up do not contacted with hydrone and slow down curing reaction speed, can also extend the work of the coating
Life-span；After coating is applied on circuit board, n-butanol is vapored away immediately, and paint solidification reaction can be smoothed out again, therefore just
Butanol does not interfere with the desired curing reaction of coating, and the working life of coating can be increased on the contrary；Polyester modified polyurethane acrylic acid
Ester resin, fluorine element modified urethane acrylate, ultra-branched polyurethane acrylate are the main film forming matter of coating；Fluorine element changes
Property urethane acrylate, in film-forming due to the presence of end group fluorine atom, reduces the surface tension of coating, so as to carry
Anti-wear performance high；Ultra-branched polyurethane acrylate and nanoscale auxiliary agent, improve hardness of paint film and pliability, enhance whole
The resistance to corrosion of individual coating；Tricresyl phosphate, manganese acetate are plasticising, enhancing material, and the paint adhesion for obtaining is good, wear-resisting
Property strong, acid and alkali-resistance, corrosion-resistant, insulation；Crosslink density is bigger in theory, and wearability is better, but the increase of crosslink density, can lead
Causing the internal stress of paint film increases, and paint film is become fragile, and causes adhesive force unstable, and ftractureed under high/low-temperature impact；Monomer with
Initiator can influence crosslink density, and the activity of monomer, degree of functionality and shrinkage factor are to determine coating characteristic (such as curing rate, soft
Pliable, hardness etc.) principal element；On the premise of crosslink density and shrinkage factor of the present invention when formulation cured is not improved, make
Coating possesses the wearability and high rigidity of superelevation after solidification, while not influenceing the adhesive force of coating, resistance to temperature impact property and depositing
Storage stability.Coating long service life of the present invention, coating abrasion performance is good, and hardness is high, it is adaptable to cell phone keyboard protective layer.
