Abstract
The invention provides an excavator coating process method which is characterized in that an original paint is modulated with a curing agent according to the proportion of 5:2, a diluent is added till the viscosity of the paint is 20 plus or minus 3S, a paint film is coated with 3 courses of finish paints, and the leveling duration is 10 minutes. A product coated by adopting the excavator coating process method provided by the invention has good leveling property, and the surface attractiveness of the product is improved.
Description
Technical field
The present invention relates to a kind of excavator coating process, belong to excavator application techniques field.
Background technology
Development along with construction machinery industry; The outward appearance of machinery also more and more comes into one's own, and especially is apparent in the external coating aspect, except the severe corrosive that guarantees the surface; The aesthetics on surface also becomes the focus that industry is paid close attention to day by day; And the leveling characteristics quality of paint is a good and bad important measurement index of application level, has both received the influence of paint self attributes, also receives the influence of construction technology simultaneously.
The coating process of excavator; Generally be to carry out according to the technical qualification that the paint delivery merchant who cooperates gives; How the finishing line that has the completed big change that also is not easy to do under existing application condition, improves painting technology so; And then improve the application level, be a problem that is worth exploration.
Summary of the invention
The technical problem that the present invention will solve provides a kind of excavator coating process of good leveling property.
In order to solve the problems of the technologies described above; Technical scheme of the present invention provides a kind of excavator coating process, it is characterized in that: former lacquer and solidifying agent were modulated with 5: 2, and adding thinner again is 20 ± 3S to painting viscosity; Film thickness is 3 road finish paints, levelling duration 10 minutes.
Coating process parameter when the leveling characteristics that a kind of excavator coating process provided by the invention draws for the orthogonal experiment of three parameters of allotment ratio through flow time, finish paint thickness, paint is best.
Utilize the product good leveling property of a kind of excavator coating process application provided by the invention, improved the aesthetics of product surface.
Embodiment
For making the present invention more obviously understandable, with a preferred embodiment, elaborate as follows now.
This test to as if the yellow finish paint of dual-component polyurethane, the allotment ratio is 5: 2, it is 20 ± 3S that viscosity requires.
The influence factor of leveling characteristics mainly contains: the viscosity of coating thickness, flow time, paint.The finish paint flow time refers to that the test plate (panel) finish paint has sprayed entering barn time span before.Under the prerequisite of finishing line technology comparative maturity, viscosity is provided with fixed value 21S, imagination is done influence a little through the ratio of changing paint curing agent and thinner to the attribute of paint.Test respectively is being provided with three gradients aspect the flow time of the thickness of allotment ratio, paint film, paint.Three or three Orthogonal Composite draw 15 set conditions, construct according to different condition.
1) test is prepared
In following three kinds of ratios allotment finish paint, corresponding Sheng paint can marked:
Former lacquer: solidifying agent mixed by 5: 2, added thinner viscosity and transferred to 20 ± 3S, No. 1 paint of mark;
Former lacquer: solidifying agent mixed by 3: 1, added thinner viscosity and transferred to 20 ± 3S, No. 2 paint of mark;
Former lacquer: solidifying agent mixed by 4: 1, added thinner viscosity and transferred to 20 ± 3S, No. 3 paint of mark.
2) spray test plate (panel)
Test 1 group, test plate (panel) of every kind of paint ratio spray, finish paint is accomplished lacquer spraying technique 3 times, and flow time 5 minutes after the surface drying, writes 1,2,3 respectively at test plate (panel) topical oil lacquer pen, and digitized representation uses the paint of corresponding code name.This test group is totally 3 samples.
Test 2 groups, finish paint spray 3 times, 2 test plate (panel)s of every kind of paint ratio spray; Flow time was respectively 10 minutes, 20 minutes before advancing barn, after the surface drying, painted pen and write 1-10 respectively at the test plate (panel) of correspondence paint, levelling duration; 1-20,2-10,2-20; 3-10,3-20 (the digitized representation paint before the horizontal line number, digitized representation flow time behind the horizontal line).This experimental group is totally 6 samples.
Test 3 groups, finish paint spray 2 times, 2 test plate (panel)s of every kind of paint ratio spray, flow time 10 minutes, 20 minutes respectively; After the surface drying, paint pen and write 2-1-10,2-1-20 respectively at the test plate (panel) of correspondence paint, duration; 2-2-10,2-2-20,2-3-10; 2-3-20 (third digit is represented flow time for first digit representative paint pass, second digit representative paint number).This experimental group is totally 6 samples.
Table 1 application certificate parameter construction reference table
Aspect the contrast of oil paint coating effect; The glossiness of paint film, aberration, thickness all have instrument can supply to measure; But leveling characteristics can only be accomplished through estimating; Way of this test leveling characteristics check is the mirror position that forms through stravismus light incident paint face, sees the profile of object and little line of paint film on every side.Image is clear more, and leveling characteristics is good more, and little line is thin more, and paint film is smooth more.
Drawing best levelling processing condition according to aforesaid method is: former lacquer and solidifying agent modulation ratio are 5: 2, and film thickness is 3 road finish paints, levelling duration 10 minutes.
Claims (1)
1. excavator coating process is characterized in that: with modulation in 5: 2, adding thinner again was 20 ± 3S to painting viscosity with former lacquer and solidifying agent, and film thickness is 3 road finish paints, levelling duration 10 minutes.
