Summary of the invention
The purpose of this invention is to provide a kind of a kind of construction method that prevents that the ultraviolet-curing paint paint film from bubbling that provides.
The concrete technical scheme that realizes the object of the invention is:
A kind of method that prevents that the ultraviolet-curing paint paint film from bubbling, comprise the steps: priming paint or finish paint application after, infrared light levelling 3.5-5 minute, the temperature of levelling is 40-50 ℃.
Wherein said construction method comprises the steps:
1) treats coated object and carry out the sanding processing;
2) treat that coated object is painted: use painted high adhesion force priming paint or the finish paint (priming coat) of ultraviolet light, UV (ultraviolet light) solidifying full dry or UV solidify half-dried;
3) ultraviolet curing transparent priming (base coat) roller coat or spraying; Infrared light levelling 3.5-5 minute then; The UV solidifying full dry, the body surface behind the UV solidifying full dry is handled in sanding, repeats the roller coat of this step or the step twice of spraying, levelling, curing and sanding again;
4) ultraviolet curing transparent finish paint roller coat or spraying, infrared light levelling 3.5-5 minute then, the UV photocuring was absolutely dry.
3, construction method according to claim 2 is characterized in that, comprises the steps:
1) treats coated object and carry out the sanding processing;
2) treat that coated object is painted: with the painted high adhesion force priming paint (priming coat) of ultraviolet light, even roller coat or spray a time, UV solidifies half-dried;
3) ultraviolet curing transparent priming (base coat) roller coat or spraying: use uv transparent priming paint; Even roller coat or spray a time; The infrared levelling 3.5-5 of ultraviolet light minute then; The UV solidifying full dry, the body surface behind the UV solidifying full dry is handled in sanding, repeats the roller coat of this step or the step twice of spraying, levelling, curing and sanding again;
4) ultraviolet curing transparent finish paint roller coat or spraying: the ultraviolet curing transparent finish paint is spraying two " ten " words (right-angled intersection method) evenly, or ultraviolet curing transparent finish paint roller coat, and infrared light levelling 3.5-5 minute then, the UV photocuring was absolutely dry.
Wherein, said infrared light levelling is meant with infrared leveling machine levelling.
Wherein, the temperature of said infrared leveling machine levelling is 40-50 ℃.
Wherein, the UV solidifying full dry also comprises the step on sanding handled object surface behind the UV solidifying full dry said step 2).
Wherein, The spraying of ultraviolet curing transparent priming in the said step 3) is specially: with the ultraviolet light polymerization reactive diluent working viscosity of ultraviolet curing transparent priming is adjusted to 14-18 second; Evenly spraying is one time, adopts the infrared light leveling machine then, infrared levelling 3.5-5 minute; UV solidifies the machine solidifying full dry, and the body surface behind the solidifying full dry is handled in sanding.
Wherein, The spraying of the ultraviolet curing transparent finish paint in the said step 4) is specially: use special-purpose ultraviolet light polymerization reactive diluent that the working viscosity of ultraviolet curing transparent finish paint is transferred to 14-18 second; Evenly spray two " ten " words, infrared light levelling 3.5-5 minute, UV solidifying full dry.
Wherein, the roller coat of the ultraviolet curing transparent finish paint in the said step 4) is: with uv transparent finish paint roller coat one time, and the infrared levelling 3-5 of ultraviolet light minute, the UV solidifying full dry, sanding, and then repeat according to twice of this technological operation.
Said curing is to adopt the UV photo solidification machine to carry out.
Said sanding is handled, and is with sand paper handled object surface, makes its sand milling smooth, smooth.
Wherein, the said coated object of treating is that medium-density plate pastes wooden skin or the made workpiece of all kinds of solid wood, and for example decorative object all can adopt the commercially available prod.The Russian pinus sylvestris var. mongolica of the preferred high-quality of said solid wood and northeast birch.
" ten " word of described spraying is meant coated article is vertically from first to last sprayed one time comprehensively, laterally from first to last sprays one time then comprehensively; Twice " ten " word presents " ten " word cross-like.
Described viscosity is meant the viscosity of being surveyed with rock field 2# cup 25 degree, and working viscosity transfers to 14-18 second.
The painted high adhesion force priming paint of said ultraviolet light (priming coat), ultraviolet curing transparent priming (base coat), ultraviolet curing transparent finish paint, and the active special diluting agent of the ultraviolet light polymerization that adopts, all can adopt the commercially available prod.
Construction method provided by the invention has the following advantages:
1, compare with existing construction method: the main distinction of the present invention is in adopting (40-50 ℃) temperature infrared light infrared levelling 3.5-5 minute, methods such as UV solidifying full dry.Adopt the technology of the infrared levelling of ultraviolet light common in this area; Help avoiding phenomenon such as paint film foaming after the application, paint film cracking, adhesive force be bad like this; As all obtaining desirable surface effect at woodwork this parts such as furniture, timber, cabinet, floors; But do not have the temperature setting during leveling machine construction, so still can't avoid occurring the phenomenon of foaming at furniture surface.The unexpected setting of finding through infrared levelling machine of inventor; Its temperature is controlled at 40-50 ℃; Flow time is 3.5-5 minute, and the product that makes in conjunction with technologies such as other sand millings, curing is in the environment of normal temperature, humidification; Phenomenons such as product surface is effective, nothing is bubbled, do not ftractureed take place, and adhesive force is good simultaneously.
2, this method can prevent effectively that the ultraviolet-curing paint paint film from bubbling, and after construction, is placed on respectively in atmospheric environment and the constant temperature humidity chamber 1 month, does not all have turn white, burst apart, phenomenon appearance such as pull-away; And the product that construction back obtains have do not contain VOC (VOC), environmental pollution is little, curing rate is fast, the saving energy, cured product performance are good, be suitable for advantage such as high-speed automated production, can satisfy handicraft solid wood or composite wood class woodwork manufacturing enterprise demands such as timber, furniture, stair, cabinet.
