Description
Technical field
The present invention relates to LED-UV woodenware transparent repair priming paint.
Background technology
At present at finishing work scene, because the imprudence or other factorses of workmen make already installed woodenware
Gadget surface, which is scratched or encountered, small depression, and field patch recovery, traditional side must just be carried out by such case occur
Method is all to carry out repairing filling using PU paints or PE paints, and the drying varniss time of traditional PU paint PE paints long (needs
Want 5-8 hours paint films to dry, carry out next process), and cause this period workmen to have nothing to do, can only be at which
In wait, so bring many inconveniences to the engineering that works to tight deadlines of scene, be easy for the delay for causing engineering to hand over the phase.
UV paints currently used in the market all have efficiently (can be achieved paint film in 3~5 seconds completely solid through ultraviolet light
Change) the characteristics of, typically all by high-pressure sodium lamp luminous radiation, carry out cross-linking and curing reaction and complete paint film forming.High-pressure sodium lamp
Because power is high (generally 80W/cm), with strong light intensity brightness, can produce ozone when very strong heat radiation and work and
Supporting cooling system is needed, therefore is unpractical in engineering construction onsite application, and the appearance of LED-UV lamps compensate for this
One defect, LED-UV lamps have power low (general portable LED-UV curing be 9~12W) heat radiation is small when working (impinges upon
Workpiece surface just increases by 3 degree or so of temperature, and 20 degree or so of workpiece surface temperature of conventional high-pressure mercury lantern festival increase), ozone free
Produce, availability is high, small volume is easy to maintenance, meet environmental protection and safety requirements.Therefore needing badly can be carried out using LED-UV lamps
The special woodenware transparent repair coating of LED-UV of solidification, to be constructed in engineering site.
The content of the invention
