Detailed description of the invention
When the mode adopting laser engraving for solving prior art makes texture on elastic coating, the technical problem that zigzag burr occur it is easy in the place of laser carving, the embodiment of the present invention is by being produced on raised grain in advance on thin film, texture on thin film is transferred on semi-vitreous elastic coating by the mode transferred by vacuum, thus realizing the grain effect of uniformity, it is to avoid when making texture, zigzag burr occur.
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
Embodiment one
The embodiment of the present invention one provides a kind of connection with production of structures method on elastic coating, as it is shown on figure 3, the method mainly comprises the steps that
Step 301, after coating elastic coating, carries out the first cured to described elastic coating, makes the described elastic coating after the first cured be in semi-molten state.
Described first cured includes: described elastic coating is carried out ultraviolet radiation, makes the elastic coating after ultraviolet radiation be in semi-molten state, is not fully cured.
Wherein, for making elastic coating reach semi-molten state, the ultraviolet energy of the first cured is less than and makes described elastic coating be fully cured required energy.
In one embodiment, the ultraviolet energy of the first cured can be chosen as make described elastic coating be fully cured required energy 1/3��1/2. Such as: selecting the ultraviolet energy of the first cured is make elastic coating be fully cured the 1/3 of required energy, 1/2,35%, 40%, 45%, 45%��50% etc. The ultraviolet radiation duration of the first cured requires depending on the concrete state of cure of described elastic coating, such as: the ultraviolet radiation duration of the first cured, 3m, 3.3m, 3.5m, 4m, 5m etc. can be selected in 3m��10m (second) scope. In principle, the ultraviolet energy of selected first cured is more big, then the ultraviolet radiation duration selecting the first cured is more little.
And make elastic coating be fully cured required ultraviolet energy between 800J��1200J (joule), and as: 800J, 900J, 1000J, 1100J, 1200J etc.
It should be noted that the method for the embodiment of the present invention one is for the workpiece completing elastic coating coating procedure, say, that the mode of the embodiment of the present invention one, for the workpiece being coated with elastic coating, is the handling process after elastic coating coating procedure. certainly, before elastic coating coating procedure, it is also possible to have other technological process, the technological process before elastic coating coating procedure is not limited by the embodiment of the present invention. such as: before elastic coating coating procedure, usually there will be the technique to the workpiece surface spraying priming paint through pretreatment, the material of this priming paint can select to be bi-component or one-can urethane coating, and the substrate material of workpiece can be metal or plastic material etc., metal material is magnalium such as, aluminium alloy, plastic material is Merlon (PC such as, Polycarbonate), acrylonitrile-butadiene-styrene copolymer (ABS, AcrylonitrileButadieneStyrene), polyamide (PA, Polyamide), polyphenylene sulfide (PPS, Phenylenesulfide) etc., workpiece after spray-applied primer is carried out baking dried, baking temperature is depending on the characteristic of primer base, generally can be 50 DEG C-90 DEG C, baking time 25-60 minute is not etc., for polyurethanes primer base, its baking temperature can be chosen to be 65 DEG C, and baking time can be chosen to be 30 minutes.
Step 302, by the mode that vacuum transfers, is transferred to the texture on the thin film with texture structure on described semi-vitreous elastic coating.
The embodiment of the present invention, according to the textured pattern to make on elastic coating, sets the textured pattern on the thin film transferred, and is produced in advance on thin film by the textured pattern of thin film; By being produced in advance on thin film by raised grain, the texture on thin film is transferred on semi-vitreous elastic coating by the mode again through vacuum transfer. It should be noted that after vacuum transfers, form veined elastic coating and be still within semi-molten state.
Wherein, the mode of vacuum transfer can be: is placed and secured in the thermal transfer device of a hollow by the workpiece after described first cured, after evacuation, the thin film of raised grain is had to be attached on the elastic coating of workpiece by making, apply certain pressure simultaneously, thus the veined thin film of surface imprint can be attached on workpiece completely, and the raised grain correspondence of film surface is printed on elastic coating, and then obtains clear exquisite texture on elastic coating.
Step 303, after transfer completes, peels off described thin film with described elastic coating.
After having transferred, from thermal transfer device, workpiece is taken out, and the elastic coating of thin film with workpiece is peeled off. The mode realizing peeling off has multiple, and the embodiment of the present invention does not limit.
Step 304, carries out the second cured to the elastic coating completed after peeling off, makes the described elastic coating after the second cured be fully cured.
Described second cured includes: described elastic coating is carried out ultraviolet radiation, has made the elastic coating after peeling off be fully cured. So, the ultraviolet energy of described second cured needs for making described elastic coating be fully cured required energy, between 800J��1200J, as: 800J, 900J, 1000J, 1100J, 1200J etc. The ultraviolet radiation duration of the second cured requires depending on the concrete state of cure of described elastic coating, for instance: the ultraviolet radiation duration of the first cured, 3m, 5m, 8m etc. can be selected in 3m��30m (second) scope. In principle, the ultraviolet energy of selected second cured is more big, then the ultraviolet radiation duration selecting the second cured is more little.
Embodiments of the invention one, first the workpiece of coating elastic coating is carried out the first cured, its elastic coating is made to be in semi-molten state, the texture made in advance on thin film is transferred on semi-vitreous elastic coating by the mode again through vacuum transfer, after being peeled off with elastic coating by thin film subsequently, elastic coating is carried out the second cured so that it is be fully cured. So, it is achieved that the grain effect of uniformity on elastic coating, it is to avoid when making texture, zigzag burr occur, thus improve exterior quality and the product quality of product.
