Description
Technical field
The present invention relates to automobile lamp manufacture and surface spraying technical field thereof, particularly relate to automobile lamp photocuring spraying coating process.
Background technology
The paint of conventional spray paint is generally heat cure paint, baking step in the spray coating process of light fixture, special roasting plant is needed to carry out high-temperature baking, waste energy, and its baking time, temperature all will control equal standard, thus ensure that light fixture has good gloss and the paint be sprayed on light fixture has stronger bonding force, avoid using peeling paint for a long time, increase its service life, thus improve the coating quality of automobile lamp.
When but high-temperature baking is carried out in traditional being sprayed on, not only waste energy, and belong to high-temperature baking due to it, temperature controls not accurate a little, larger impact can be caused on the paint quality after spraying, especially the glossiness of the paint of lamp surface and degree of adhesion impact larger.But the light fixture of different materials spraying same paint or commaterial spray different paint temperatures and control to be all different, present most of temperature controls also to belong to micro-judgment, nothing data accurately, the coating quality of automobile lamp is difficult to be protected, defect rate is higher, need the coating quality of repeated multiple times spraying guarantee light fixture, efficiency is lower.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides automobile lamp photocuring spraying coating process, its object is to the qualification rate improving automobile lamp spraying, reducing its rework rate, and improving the production efficiency of automobile lamp further.
The technical solution adopted in the present invention is: automobile lamp photocuring spraying coating process, in turn includes the following steps:
A. prepare before spraying, adopt isopropyl alcohol light fixture use, remove the dust on light fixture and electrostatic thereof, and be placed on the intermediate transportation equipment of isopropyl alcohol process, wait to be sprayed;
B. spray, be placed in fixtures for painting or spraying box and light fixture sprayed, until the paint spraying on the area of lamp surface more than 90 percent is even;
C. light fixture is heated, after the spraying of step B completes, directly heating light fixture or light fixture is placed in heating cabinet shows to heat to light fixture, make the paint levelling be sprayed on light fixture, until light fixture shows that paint is evenly, the heat time is no less than 15min;
D. dry, after step C completes, use the Ultraviolet radiation light fixture that wavelength is 320-390nm, make it show paint drying, drying time is no less than 28min;
E. after having dried, leave standstill and be no less than 5min, take out light fixture stand-by.
Further improvement of the present invention is, if to same light fixture spraying multilayer paint, after step D completes, need directly enter step B circulation spraying.Realize the spraying of the multilayer paint of same light fixture.
Further improvement of the present invention is, the ultraviolet generator in described step D is for adopting ultraviolet light fluorescent lamp and or mercury vapor lamp.
Further improvement of the present invention is, the drying time of described step D is 35-55min, just can obtain good drying effect.
Further improvement of the present invention is, the time of repose of described step e is 10-30min, to spray paint the cooling of the light fixture after drying, avoids light fixture to scratch lamp surface in the handling process in later stage, plays good protective action to its surface.
Compared with prior art, the invention has the beneficial effects as follows: the paint of conventional spray paint is generally heat cure paint, uses up now solidification paint, during oven dry, high-temperature baking wanted by heat cure paint, and photocuring paint only need with ultra violet lamp, so not only product percent of pass is high, and rework rate is low, and, fixture easily cleans, and efficiency is also high, goes back environmental protection and economize energy.Because characteristics such as speed that ultraviolet curing has curing of coatings are fast, film quality is good.
Accompanying drawing explanation
Fig. 1 is automobile lamp photocuring spraying coating process flow chart.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is further described, and this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
Refer to Fig. 1, automobile lamp photocuring spraying coating process, in turn includes the following steps:
A. prepare before spraying, adopt isopropyl alcohol light fixture use, remove the dust on light fixture and electrostatic thereof, and be placed on the intermediate transportation equipment of isopropyl alcohol process, wait to be sprayed, see 101 steps;
B. spray, be placed in fixtures for painting or spraying box and light fixture is sprayed, until the paint spraying on the area of lamp surface more than 90 percent is even, see 102 steps;
C. light fixture is heated, after the spraying of step B completes, directly heating light fixture or light fixture is placed in heating cabinet shows to heat to light fixture, make the paint levelling be sprayed on light fixture, until light fixture shows that paint evenly, the heat time is no less than 15min, see 103 steps;
D. dry, after step C completes, use the Ultraviolet radiation light fixture that wavelength is 320-390nm, make it show paint drying, drying time is no less than 28min, see 104 steps;
E. after having dried, leave standstill and be no less than 5min, take out light fixture stand-by, see 106 steps.
In the above-described embodiments, if to same light fixture spraying multilayer paint, after step D completes, need directly enter step B circulation spraying, see 102,103,104 and 105,106 steps.Realize the spraying of the multilayer paint of same light fixture.
In the above-described embodiments, the ultraviolet generator in described step D is for adopting ultraviolet light fluorescent lamp and or mercury vapor lamp.Adopt simple UV-sunlight lamp, ultraviolet light fluorescent lamp is that enclose a small amount of mercury, in pipe, mercury pressure is 1.33 ~ 1333.32Pa at inner surface of tube coating fluorescent substance.The work rate of usual this lamp is 0.8W/cm, 20% ultraviolet being equivalent to 320 ~ 400mm wavelength of light efficiency, and therefore effective power is 0.16W/cm, and work temperature is 35 ~ 40 DEG C, so do not need cooling device.Mercury vapor lamp tube wall temperature can reach 700 DEG C, must could apply by heating/cooling device.In order to improve the illumination efficiency of ultraviolet source, the reflecting plate that aluminium alloy is made usually to be installed additional.The exhaust apparatus of the ozone, film evaporant and the tempering air that are produced by light source, reflecting plate, supply unit, cooling device, conveyer, discharge bulb, whole screening arrangement, constitutes UV curing apparatus.
In the above-described embodiments, the drying time of described step D is 35-55min, just can obtain good drying effect.
In the above-described embodiments, the time of repose of described step e is 10-30min, to spray paint the cooling of the light fixture after drying, avoids light fixture to scratch lamp surface in the handling process in later stage, plays good protective action to its surface.
The photocuring spraying coating process of the application, the paint of relative conventional spray paint is generally heat cure paint, uses up now solidification paint, during oven dry, high-temperature baking wanted by heat cure paint, and photocuring paint only need with ultra violet lamp, so not only product percent of pass is high, and rework rate is low, and, fixture easily cleans, and efficiency is also high, goes back environmental protection and economize energy.Because characteristics such as speed that ultraviolet curing has curing of coatings are fast, film quality is good.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and change; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
