Description

Explosion-proof muscle or sagging environment-friendly type photocuring height spacer-frame this tinting material beautiful
Technical field
The present invention relates to the painted or filling technique of IPC International Classification of Patents C09C inorganic materials or C09D coating composition coating technology, especially explosion-proof muscle or sagging environment-friendly type photocuring height spacer-frame this tinting material beautiful.
Background technology
Current furniture primer painting process is mainly main with polyurethane(s) (Polyurethane, abbreviation PU, is called for short urethane) or unsaturated polyester varnish (PE), and the levelling property of this two classes paint is excellent, and good sanding, adhesion performance is good.But volatile matter (VOC) content higher (about 50 ~ 60%), pot-life short (paint prepared need use as early as possible), temperature influence is comparatively large, and production efficiency is low, hinders the development of furniture enterprise.UV paint is the abbreviation of ultraviolet light cured paint (Ultraviolet Curing Paint), also light-initiated coating is claimed, photo-cured coating, be coated to after on furniture plate surface, decomposition of initiator is impelled under the irradiation of UV-light, produce free radical, causing resin reaction, instantaneous solidification film forming, is the paint of current most environmental protection, have the following advantages: (1) UV paint film is stereo structure structure, hardness is large, and wear resistance is good, and transparency is good, the resistance to scratching of product, rub resistance, stand the test of time; (2) mechanised equipment overcomes the human factor in manual operation, makes product aberration less, steady quality; (3) in making processes, the objectionable impurities in sheet material is decomposed, and by ultraviolet photo-curing machine drying and processing, product is health environment-friendly more.Along with UV paints the increase of the ratio in furniture at home, the construction technology of traditional solvent-borne wood lacquer is also also incorporated in UV paint by user, such as antique coating technology etc.Photo-cured coating mainly refers to a class new coating of rapid crosslinking curing film forming under UV-irradiation, because of its efficient coated solidified and environmental friendliness feature, by world's coating industry and most administrations are approved, widely uses at furniture industry.Current most photocuring Ge Lisi contains a large amount of nitro-cotton and organic solvent, not only in construction process curing efficiency low, discharge a large amount of organic solvent pollution environment, human body damaged, also easily cause wood surface application to occur sinking, the phenomenon such as quick-fried muscle, it is not also very smooth for using at furniture industries such as such as office furniture, suite room furniture, timbers.
Ge Lisi is a kind of to be translucently made up of in oil solvent to transparent pigment colorant resin dissolves, dry slow, can by wiping, grooming and do level light and shade, makes that integral color is soft, nature, gradation sense strong, and the overwhelming majority is use in NC paints.Color can be inserted in the pore of timber by Ge Lisi, and can be adjusted the light and shade depth of color by wiping, and increasing the gradation sense of film color and the sharpness of wood grain, is the indispensable color-tinted product of American and European style.The solid wood being mainly used in nitro application, the obliterating of pasting the various wood furniture products such as wooden skin are painted, are also applied to the false wood grain garland of density board edge sealing of nitro application.Ge Lisi tinting material: can be described as antiquing paint again, is in slow curing and the oil being easy to wiping or resin, translucent or transparent pigment is dissolved in made by oil solvent.Its object is to utilize its translucency to reduce brightness, make face soft, formed when hatching effect, produce classic interest and hide.
Published improvement opportunity is less.
Chinese patent application 201310208024.1 provides a kind of UV Ge Lisi, comprising: bisphenol type epoxy acrylic resin 5-10 weight part; Reactive thinner 5-10 weight part; Nitro-cotton 5-8 weight part; Dispersion agent 0.01-1 weight part; Peace bar powder 5-10 weight part; Solvent 50-80 weight part; Light trigger 1-1.5 weight part.And solve the pungency to human body in the use procedure of UV paint, can be applied in the antique coating of multiple woodwork furniture.
Chinese patent application 201110079237.X is used for Ge Lisi wiping stain of coating aqueous carpentry and preparation method thereof and belongs to paint field.Wiping stain comprises color development component and fixation component.Color development component contains a kind of pigment carrying and the amphiphilic polymers resin of cohesive action, and pigment is well sprawled and infiltration at wood surface; Fixation component contains acrylic ester polymer, has excellent tint retention and weathering resistance.
Chinese patent application 201210507675.6 relates to a kind of ultraviolet light polymerization (UV) electrostatic spraying transparent priming woodwork coating, this coating by A, B two component form, component A is made up of following composition, epoxy acrylate (EA), modified epoxy acrylic ester (EA), reactive thinner, defoamer, dust-proofing agent, color stuffing, light trigger, B component is made up of following composition: vinyl acetic monomer.Its construction technology: component A and B component are in 100:10-15 ratio mixed construction.
