Description
Technical field
The present invention relates to technical field of coatings.
Background technology
Ultraviolet light currently on the market（UV）Solidification white paint is cured together with the two kinds of lamp source combinations of mercury lamp and gallium lamp,
The based white primer that height covers（Refer to titanium white powder content and accounts for formula 40% or more）Very strong gallium lamp solidification energy is needed just to can guarantee coating
Thorough solidification drying.Such curing mode has the following disadvantages：
1, high energy consumption, and the utilization rate of energy is low.Ultraviolet light utilization ratio only accounts for about 30%, and infrared ray and other heat radiations
60% is accounted for, so most input power switchs to thermal energy so that the temperature of fluorescent tube is very high, and substantially reduce fluorescent tube uses the longevity
Life needs to be replaced frequently fluorescent tube, and to base material（Especially to the base material of thermal sensitivity such as plastics, film, paper）It is unfavorable to generate
It influences.
2, a large amount of ozone are generated, are meet the requirement of environmental protection, need that emission-control equipment increase equipment input cost is installed.

A kind of above-mentioned high preparation method for covering LED solidification based white primers, first by six official's aliphatic urethane acrylates
In oligomer, the bisphenol A modified epoxy acrylate of two degrees of functionality and polyester acrylate oligomers input container, dispersion machine is used
600-800rpm/min disperse 5-6min to be uniformly mixed；Then aerosil, photoinitiator, reactive amines are put into and help initiation
Agent and rutile type titanium white disperse 15-20min sample detections with dispersion machine 1200-1500 rpm/min, when fineness reaches≤
When 25um, auxiliary agent is put into, disperses 5-6min to being uniformly mixed with dispersion machine 600-800rpm/min, obtains high covering LED solidifications
Based white primer coating.
Since LED lamp source only emits ultraviolet light in several very narrow wave bands such as 365nm, 385nm, 395nm, 405nm, do not have
There is short-wave band so that traditional superficial layer initiator such as 1173,184, BP, reactive amines etc. cannot play a role.The present invention
Key technology is by screening the photoinitiator to match with LED lamp source emission spectrum, and draws by the way that compounded combination is a variety of
The unification that colored paint film surface layer and deep cure are realized in agent is sent out, the dry and comfortable anti scuffing of film surface drying is made, thick can be applied with very strong
Adhesive force is excellent simultaneously for covering power.
The high based white primer that covers of the present invention uses LED lamp source curing mode, in solidification process environmental protection do not generate ozone, LED
Low energy consumption for lamp source, usually only between several watts to tens watts, the about a quarter of conventional high-tension mercury lamp.And LED light
The spectrum of light source transmitting compares concentration, concentrates on a narrowband（365-395nm）, therefore the utilization rate of energy is high, substantially without red
Outer heat generates, and is suitably applied temperature-sensitive material, has well solved destruction of the conventional curing mode to temperature-sensitive material.Separately
Outside, LED only emits ultraviolet light, these long wave bands in several very narrow wave bands such as 365nm, 385nm, 395nm, 405nm at present
It can be good at " penetrating " colored paint film（When especially film is thicker）, there is inborn advantage to the deep cure of colored paint.
The invention has the advantages that：
1, low energy consumption for LED light source, usually only between several watts to tens watts, the about a quarter of conventional high-tension mercury lamp.
2, the spectrum of LED light source transmitting compares concentration, and the utilization rate of energy is high, and is generated substantially without infrared heat,
It is suitably applied temperature-sensitive material, has well solved destruction of the conventional curing mode to temperature-sensitive material.
3, the deep layer that the high white paint covered uses LED light curing ratio conventional high-tension mercury lamp that can preferably solve paint film is solid
Change problem ensure that adhesive force of the paint film to workpiece.
4, environmental protection does not generate ozone in solidification process, environmental-friendly, is the curing mode that future market is chased.
