Description

A kind of LED-UV solidifies coating process and application thereof
Technical field
The present invention relates to a kind of coating process field, particularly relate to a kind of UV-LED and solidify coating process and application thereof.
Background technology
Wood decorative lamination decoration board utilizes natural seeds fancy veneer or artificial wooden fancy veneer by the veneer that accurate wound is cut or rotary-cut processing method is obtained, is attached on base material, adopts advanced adhesion process, through a kind of flawless finish sheet material that hot pressing is made.Decorative panel is as a kind of surface decoration material, can not be used alone, certain thickness can only be pasted onto and have on the backing material plate of some strength, as inorganic board, plastic plate, solid wood board, lumber core, multi-plywood, medium density fibre board (MDF) and particieboard etc., just can reasonably be utilized.Natural wood veneer veneer has natural wood decorative pattern, textured pattern nature, and variability is larger, random, and prosthetic is affected, and the sense of reality and third dimension by force, are widely used in interior decoration.As carried out UV application to timber, need to carry out UV solidification, and often use UV mercury lamp to have some defects as radiation source, the service life of UV mercury lamp is short, by mercury and as accessory substance ozone form the environmental problem that can cause.In addition, mercury lamp has lower energy conversion rate usually, needs preheating time, a large amount of heats can be produced during operation, need blower fan to cool, thus produce noise pollution, and heat-sensitive substrate material easily causes distortion after being heated, thus affects the attractive in appearance of product and quality, also limit it and use.Although UV-LED light source has extra long life, high, the customizable effective irradiation area of snap switch energy, not mercurous, also can not produce ozone, energy consumption low, to eyes and the plurality of advantages such as skin irritatin is little, but be mainly applied on widget now, as electronic applications, as on the parts such as optics, mobile phone, touch-screen, hard disk, encoder, thus limit its application.Although Chinese patent CN201080055758.5 discloses the LED solidification of radiation-hardenable floor paint, the patent provides a kind of be suitable for being solidified by LED radiation-hardenable floor paint and a kind of method with this coatings floor and a kind of coating floor of coating containing being prepared by this coating is provided, this coating process is only applicable to floor, and be not suitable for wooden decorative lamination decoration board, and and unresolved heat-sensitive substrate material cause after being heated be out of shape problem.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, an object of the present invention is to provide a kind of UV-LED and solidify coating process, effectively can solve heat-sensitive substrate material because of yielding problem of being heated, but also there are energy-saving and environmental protection, not mercurous, also can not produce ozone, to eyes and the advantage such as skin irritatin is little.Another object of the present invention is also to provide above-mentioned UV-LED to solidify the application of coating process, and involved field comprises the production of decorative board for wall, solid wooden floor board, solid wood composite decorating board.
For solving said method problem, the present invention by the following technical solutions:
First timber is attached on base material, adopts advanced adhesion process to carry out gluing, and then carry out UV-LED solidification application.
A kind of UV-LED solidifies coating process, it is characterized in that: it comprises the following steps:
Step 1, employing colouring agent carry out painted to timber; Step 2, the timber after polishing to be carried out to application UV-LED coating material solidified; Step 3, carry out UV-LED solidification by UV-LED light source to being coated with the timber that installs.
Colouring agent described in step 1 is any one or more than one the mixing in the painted adhesive agent of water-based, water soluble dyestuffs or aqueous color paste, coated on timber by any one mode in spraying, showering, roller coat, brushing, obliterating, dip-coating and painted and Seal treatment is carried out to timber, and adopt far-infrared ray drying, infra-red drying, microwave drying or heated-air drying any one or more than one mode drying is carried out to the timber after painted, make it reach the effect of uniform coloring and closed timber pore simultaneously.Polishing can be carried out to wood surface after drying, remove wood thorn.
Application UV-LED described in step 2 is coating material solidified, comprise that UV-LED solidifies adhesion primer, UV-LED solidification infiltration priming paint, UV-LED curing transfer glue, UV-LED solidify putty, UV-LED curing transparent priming, UV-LED solidifies at the bottom of sanding priming paint, UV-LED solidified wear resistance, UV-LED solidifies showering varnish, UV-LED solidifies solid color enamel " comprise UV-LED and solidify white paint ", UV-LED solidify in finish paint any one or more than one, the number of channels of each coating be together or together more than, and the coating material solidified order of application UV-LED is according to needing suitably to adjust.
The coating material solidified total coating weight of UV-LED described in step 2 is 10-350g/m 2, every one coating weight can be 5-150g/m 2, the coating method of application is any one in showering, spraying, roller coat, brushing, obliterating, dip-coating, and wherein roll coating model comprises just against roller coat, common single and double in the same way roller coat, radium-shine single or two roller coat.
What the UV-LED light source described in step 3 adopted is wavelength is 260-450nm, and energy is 50-1000mj/cm 2uV-LED light source, the UV-LED light source of preferred wavelength to be 360-420nm or wavelength be 260-360nm, 1-2 UV lamp of arranging in pairs or groups, UV lamp comprises UV mercury lamp, UV gallium lamp or UV iron lamp.
UV-LED solidification process described in step 3 is cured on streamline with the speed of 1-20 m/min, and light application time is 1-20S.
There is the conventional light trigger of absorption bands between 360-450nm on the market now, select the light source efficiency of initiation of this wave band high, if wavelength is oversize, belong to visible region, in sunshine, the content of visible ray is up to 40%-55%, easily causes paint solidification, thus causes coating decoration inconvenient.
Described a kind of UV-LED solidifies coating process, except being applicable to the subsides wood finishing of inorganic board, stone material, is particularly useful for the subsides wood finishing of heat-sensitive substrate material.Heat-sensitive substrate material comprises plastic basis material, solid wood base material, lumber core, particieboard, moist-proof board, glued board, core-board medium density fibre board (MDF) or other hardboards.Because UV-LED belongs to cold light source, effectively can solve the problem of heat-sensitive substrate material because being out of shape after being heated, and UV-LED light source use procedure water cooling, effectively can solve UV mercury lamp solidification process needs to utilize blower fan to cool and the noise problem that produces.
