Specific embodiment
The present invention provide it is a kind of spill a little and the surface treatment method that combines of silk-screen peelable glue, for make the purpose of the present invention,
Technical solution and effect are clearer, clear, and the present invention is described in more detail below.It should be appreciated that described herein
Specific embodiment is only used to explain the present invention, is not intended to limit the present invention.
It is of the invention a kind of to spill a little and the surface treatment method that combines of silk-screen peelable glue comprising step:
A, the spray-applied primer on plastic casing;
B, silk-screen LOGO;
C, silk-screen peelable glue;
D, it spills a little, removes peelable glue;
E, point protection paint is spilt in spraying;
F, spray paint.
Spilt from existing masking different using protective film, the present invention utilizes silk screen printing process peelable at one layer of designated position silk-screen
Glue, while silk-screen LOGO is imprinted on peelable glue in advance in the following, improving actual life to reduce the process of a material silk-screen
Produce efficiency;In addition, peelable glue of the present invention can be stamped quickly, while can easily be got rid of, reduces priming paint and damage and go
Except other are bad caused by veil process, production yield is effectively increased.
Specifically, in step A, then the plastic shell surface of the clean mobile phone of pre-cleaning is sprayed at 20 ~ 30 DEG C of spraying temperature
It primes, is toasted 8 ~ 10 minutes at flow time 3-5 minutes, 65 ~ 70 DEG C.Preferably, priming paint can paint P-306 using UV.For
Increase adhesive force, the base coat thickness of spraying are 13 ~ 18 μm.
Specifically, in step B, silk-screen LOGO is on priming paint, and in silk-screen printing process, control silk-screen pressure is 3 ~ 4kg/cm, silk
Print-out rate is 4 ~ 5m/min.Preferably, the present invention is using UV-KW ink silk screen printing LOGO on priming paint.
Specifically, in step C, since peelable glue is the viscous liquid for having certain viscosity, the present invention uses silk screen process
Method scraper in silk-screen LOGO corresponding position silk-screen peelable glue, silk-screen peelable glue the angle of attack between 45 ~ 50 degree, 50 ~ 65
It is toasted 5 ~ 10 minutes at DEG C.Peelable glue is a kind of one-component silk-screen protection ink, can be used as a kind of protective layer masking and spills a little.In order to
Allow when removing more more easily, cleans before silk-screen peelable glue to the plastic casing after step B, removes spot.When operation, use
18T silk screen below and 60 degree of fillet polyurethane scraper, to ensure that peelable glue has certain thickness, in favor of removing.For
Further ensure that peelable glue has certain thickness, the angle of attack of present invention scraper in coating is between 45 ~ 50 degree.And this hair
The speed of scraper is slow than usual when bright coating, to ensure to play the role of protection.The degree of baking and curing influences removing
Very big, the present invention takes to toast at 135 ~ 145 DEG C 25 ~ 30 minutes in heated-air circulation oven, and peelable glue has after solidifying in this way
High elasticity, to improve peeling effect.
Specifically, in step D, using a spray gun spraying sprinkling paint is spilt, control sprinkling paint viscosity is 55 ~ 65s, sprays air pressure
For 0.3 ~ 0.4MPa, 25 ~ 35min is placed after spraying sprinkling paint, is then dried at 55 ~ 65 DEG C, then removes peelable glue.Increase
Spray sprinkling paint, it is therefore intended that make product surface formed it is fragmentary it is heterochromatic intersperse, sprinkling paint appearance is beautiful, decorative strong.Preferably,
Sprinkling paint of the present invention can be polyurethane paint, amino-stoving varnish, alkyd paint etc. according to main film forming substance.It is highly preferred that of the invention
Sprinkling paint uses polyurethane paint.When spraying sprinkling paint, the present invention selects the nozzle being relatively large in diameter will be thick under lower air pressure
Thick sprinkling paint liquid is sprayed into sparse raindrop shape varnish stain and is sprinkled upon in plastic shell surface.Preferably, control sprinkling paint viscosity be 55 ~
65s, spraying air pressure are 0.3 ~ 0.4MPa.This is because it is good to spill an effect under above-mentioned viscosity and spraying air pressure, " point " uniformly and
Size is suitable, meets aesthetic effect.It is placed at room temperature for 25 ~ 35min after having sprayed sprinkling paint, 55 ~ 65 after waiting sprinkling paints completely dry
It dries or is spontaneously dried for 24 hours at DEG C, then remove peelable glue.
Specifically, in step E, spraying spills point protection paint with a thickness of 15 ~ 20 μm, and spraying process is spraying temperature 20 ~ 30
At DEG C, toasted 8 ~ 10 minutes at flow time 3 ~ 4 minutes, 65 ~ 70 DEG C.Preferably, the present invention selects epoxy resin or polyurethane
As spilling point protection paint.
Specifically, in step F, for the finishing coat of spraying with a thickness of 18 ~ 22 μm, spraying process is stream at 20 ~ 30 DEG C of spraying temperature
It is toasted 8 ~ 10 minutes at 2 ~ 4 minutes, 65 ~ 70 DEG C between usually.Preferably, by weight, it is pressed using UV paint MQ316 and YJ407
