Lift veneer and surface treatment method thereof
Technical field
The invention discloses a kind of elevator materials used, specifically is a kind of lift veneer and surface treatment method thereof.
Background technology
Lift veneer as outer guidance panel, operation box panel, lift-cabin wall panel, push button panel etc., generally is directly to make of metal or nonmetal plate at present, for example: with stainless steel sheet, aluminium alloy plate or other alloy sheets, or adopt plastics, bakelite etc.; Also have plenty of at the direct versicolor paint of coating or spray paint of metal material surface, to increase appearance colour.
The employing rubberbase paint that the present invention proposes is made the elevator decorative sheet, is not occur as yet in the prior art.But being used in, the rubberbase paint making coatings have hoot to occur on other products, the patent No. for example: 200410016876.1, " a kind of comb and surface treatment method thereof " is that coating comprises that bottom silver paint, middle edematus paint film and top layer are that transparent elastic rubber paint paint film layer constitutes on the plastics blank.They all are not only identical with prescription of the present invention and processing method and final decorative effect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of lift veneer and surface treatment method thereof are provided, this elevator trim board is used for making outer guidance panel, operation box panel, lift-cabin wall panel and the push button panel etc. of elevator, the surface has fine and smooth matte and high resilience and flexible sense and multicolour, the enjoyment that magnificent attractive in appearance, the transparent gloss of outward appearance is given a kind of dim U.S. of people.
The invention provides a kind of lift veneer, it is characterized in that: it is made of rigid plastic base substrate and the rubberbase paint coating that is coated on this billet surface.Described rigid plastic base substrate can be the 100%ABS rigid plastic, also can be PVC, PC, UPE and has sprayed on other frosting of special priming paint.Described this facing plate can be used as outer guidance panel and/or operation box panel and/or the lift-cabin wall panel and/or the push button panel of elevator.
Above-mentioned lift veneer, wherein rubberbase paint coating comprises rubberbase paint/paint, curing agent/hardener and three part compositions of auxiliary agent/diluent; Their prescription (calculating by weight) is: rubberbase paint: curing agent: auxiliary agent=100:8~10:20~40; Wherein the weight of auxiliary agent is decided according to the required viscosity of spraying.
The present invention also provides a kind of surface treatment method of lift veneer, and it comprises following five steps: 1, cleaning: clean, deoil and the surface of rigid plastic base substrate of drying forming with isopropyl alcohol (IPA); 2, stir: after the rubberbase paint coating that proportioning is good stirs, after gauze or silk screen filter; 3, spray: spray gun is chewed narrowed, air pressure is opened little, squirts as far as possible, sprays three to four layers continuously; 4, oven dry: after the workpiece after the spraying need be put 5~10 minutes, just can put into baking oven toasts dried, generally be in 70 ℃~80 ℃ 30~45 minutes, can obtain strong adhesion, the transparent whippy again rubberbase paint rete in top layer---double component polyester rosin products, can not natural air drying; 5, cooling: the plastic plate after the oven dry is put 4~6 hours cooling backs and is used.
The specific embodiment
Further describe detailed technology content of the present invention and embodiment below.
Adopt lift veneer provided by the invention, outer guidance panel/panel block/car walls/the button of made, be to make the rigid plastic base substrate earlier according to the shape of former outer guidance panel, panel block, car walls, button, provide the aforesaid processing method of the present invention to carry out surface working again on the surface of base substrate, obtain especially elevator element as the matte sense of touch.This surface has that outward appearance is magnificent, texture good, color is lively and tool flash effect and the fine and smooth soft characteristics of sense of touch.
For outer control box/box, because of comprising push-botton operation partial sum box body, so on the surface of box body, be coated with prime coat and rubber face enamelled coating.Described product adopts special surface treatment, and this series is main film forming substance by double component polyester, has good adhesive ability on rigid plastic such as ABS.Paint film comprises from the inside to the outside: bottom priming paint paint film layer can be mixed with shades of colour priming paint, the elastic rubber paint paint film layer that the top layer is transparent.Resinous type: be mainly the double component polyester resin
Toxicity is required: content of beary metal meets ATSM F963-96a and EN71:Part3:1994 standard.
Dilution is required: open the bung of rubberbase paint/paint kettle before the dilution earlier, the accretion at the bottom of the bucket is stirred evenly with Metallic rod (as aluminium matter angle bar).Paint in the dilution proportioning is generally AT-001; Curing agent/hardener is 100#; Auxiliary agent/diluent is T-103; Dilution dosage is on quantity for spray viscosity and need effect to decide.The oil and the hardener that mix are stirred evenly, after filtering with gauze again, can spray.The prescription of auxiliary agent generally is: dimethylbenzene 25%~35% and isobutanol IBA75%~65%; Wherein the content of dimethylbenzene has determined the solvency power of rubberbase paint paint film.
Spraying is required: at first need the workpiece of spraying to deoil, clean and the drying processing before the spraying.Surface treatment can be used surface treating agent.Attention is chewed spray gun and is narrowed, and air pressure is opened little, squirts as far as possible, sprays three to four layers continuously.Described spray gun is chewed diameter: 1.0~1.5mm; Spraying air pressure: 2.5~4.0kg/m
2The distance that rifle is chewed with workpiece is: 100~250mm; The nozzle diameter is: 1.0~1.5mm; Spraying air pressure: 2.5~4.0kg/m
2Nozzle and workpiece distance are generally: 100~250mm.Wherein the workpiece film thickness is generally at 10~40 ц m.Baked/oven dry: the part after the spraying need be put 5~10 minutes, but just Fang Ru oven Jin is Hang baked dried, it is desirable to dry 30 minutes in 80 ℃, and attention can not natural air drying.
Color: the depth of color and it is chosen as required, and rubberbase paint has shades of colours such as grey colour system, red colour system, blue system, yellow system, and then the product that obtains various colors is for user's selection.
By the goods that above-mentioned technology obtains, its surface especially as high resilience as the soft rubber, transparent color and luster, and have very soft mute Shamian Island gloss experiences for the sense organ of a kind of dim U.S. of people.Owing to can allocate neatly and make versicolor priming paint, can present the effect of different colours at the bottom of different grounds and the look, it is attractive in appearance various that product is had more.The rubber lacquer painting has improved the sense of touch of hand and panel, the ice-cold sense in the time of can eliminating greasy feeling when using summer, viscous sense and winter operation fully.It has magnificent outward appearance, fine and smooth matte high resilience and flexible sense product after surface treatment, and the transparent gloss of multicolour gives the sensation of a kind of dim U.S. of people, and color and tool flash of light characteristics give people with brand new elevator aesthetic effect.
