Description
Technical field
The invention belongs to car refinishing paint automatic governing fields, and in particular to a kind of car refinishing paint bulking value mixing tune
Color method.
Background technique
Automotive paint breakage needs spray car mending paint again.The each not phase of color masterbatch needed for different car refinishing paints
Together.In order to meet the needs of different automobiles, there are many color masterbatch type needed for automobile coating color matching, probably there is 50 to 90 kinds, far more than
The type of emulsion paint.Need to be equipped with so many color masterbatch cylinder on car refinishing paint mechanical colorant dispenser, required space is very big.For appointing
A kind of car refinishing paint Automatic color matching requires paint cup and is accurately moved to splicing before institute's color masterbatch cylinder in need, this will
Mechanical colorant dispenser is asked to have accurate and complicated transmission system, to improve cost.Therefore one kind is needed to take up space small, cost
Low car refinishing paint mechanical colorant dispenser.
Before car refinishing paint spray painting when being matched colors, common method first is that compared using colour atla and vehicle color,
The colour atla for finding same color, found from the color matching software database in computer in colour atla number the colour atla number color masterbatch ratio and
Each color masterbatch formulation by weight mixes and colour atla solid colour according to the artificial color masterbatch for needing type of weighing of formula, mixing, stirring
Car refinishing paint (may be simply referred to as automobile coating) below.Man efficiency is low and the car refinishing paint that mixes according to colour atla is usual
And the color of automobile has certain deviation sometimes, needs artificial further adjusting, bothersome arduously and to the technical requirements of toner
Automobile coating that is higher, needing experienced allotment work that can just mix solid colour.
In existing technology, the model or paint code of also with good grounds automobile find the formula to paint when factory or utilize light
It learns instrument (spectrophotometer) and measures car surface paint, obtain the method with paint formula, obtaining compounding method in this way can be suitble to greatly
The analysis of partial automobile surface lacquer, it is relatively accurate, reduce and formula is obtained according to vehicle or paint code mix automobile coating and reality
The error of automobile coating color.Even if in this way, count before statistics indicate that there is the car surface paint of significant proportion primary
Still there is color difference after color matching, it is desired nonetheless to further Man-made Color Matching amendment.So the color matching pair of current car refinishing paint
Artificial requirement is high, and dependence is big, and Man-made Color Matching low efficiency, one day, the energy very big with colo(u)r specification in the paint shop especially having
Reach tens kinds or hundreds of, a color matcher cannot all be completed, and some shops even need two or four color matcher.Even if this
Sample, due to large labor intensity, environment is poor (be stained with everywhere color, or even with), and technology, which improves, needs prolonged accumulation, people
Still it is unwilling this work of dry color matcher.On the other hand, to recruit an outstanding color matcher is also extremely difficult, wage
Low no one is dry.And current color technology work is necessary, and only one, seldom paint shop or toning is measured for toning
Auxiliary activities (if any the shop 4S) with the paint income top not salary of a lacquer man.So on the market if any a kind of automatic standard
The equipment for really deploying each color matching color masterbatch amount, can reach and improve efficiency, reduce blending technology requirement, reduce the purpose of labour cost.
There is enterprise development to go out car refinishing paint mechanical colorant dispenser in recent years in fact.But it could not simultaneously form stable product
It puts goods on the market.It is known that existing mature and general automobile coating shading process is all the side using weight ratio in the world
Formula, and be to pour out color masterbatch weighing color matching toning from paint can manually.I.e. according to the weight demands of required color matching color masterbatch, from top
Color masterbatch is poured out by the grout outlet that slurry covers manually in color masterbatch bucket equipped with slurry lid.Required color matching color masterbatch is weighed up on electronic scale
Weight.Color matching color masterbatch in each formula pours out weighing from color masterbatch bucket in this way and reaches required weight.It is stirred color matching
Color masterbatch, the color matching of color paint needed for completing.The slurry lid has agitating function and manually controls color masterbatch pouring function.At present in the world
Make car repair paint toning color masterbatch producer (such as: newly into, Du Pont, PPG, BASF) toning formula be all according to weight ratio
Come what is designed.
Using weight ratio, the benefit of paint toning has two o'clock manually:
1 pours out the desired amount of color masterbatch conveniently from color masterbatch bucket, and control flow capacity also facilitates: as long as the required weight in observation weight scale
Amount near when, what manual control gradually slowed down color masterbatch pours out speed, it is made slowly close to required weight of pouring out, to the last to reach institute
The color masterbatch weight needed stops pouring out for color masterbatch.Others color matching color masterbatch also after the same method complete needed for weight pour out and
Weighing；
2, which need several color masterbatch matched colors that can pour into a container, directly stirs evenly: for example, if needing with a color
Three kinds of color masterbatch are wanted, the weight of each color masterbatch is respectively that A color masterbatch needs 1.1 grams, 2.2 grams of B color masterbatch need, 3.3 grams of C color masterbatch need, can be one
A empty barrel is put on electronic scale, and weight is reset.A color masterbatch is poured into empty barrel, until electronic scale is shown as 1.1 grams.Electronic scale
It resets, then pours into B color masterbatch, until electronic scale shows that weight is 2.2 grams；Electronic scale is reset again, C mill base is poured into, until electronics
Scale shows 3.3 grams.Three kinds of color masterbatch are stirred evenly with stirring ruler finally, complete color matching toning.
It the use of weight toning is the initial natural selection of history of mixing colours.In order to avoid by the ratio of experience toning color matching color masterbatch
Cannot accurately learn cannot accurately control with color masterbatch requirement, produce the weight of most convenient realization on the basis of experience toning
Rule of three is accurately matched colors.
Theoretically being matched colors using volume ratio is also to set up.But the volume ratio colour matching method theoretically set up is in practice very
Hardly possible is realized.Volume ratio toning method obtain required volume color matching color masterbatch idea there is several methods that: imagination 1: be color masterbatch hand
It is dynamic to pour into measuring cup, the color masterbatch amount poured into is controlled according to the volume markings amount cursor position eye-observation of measuring cup.But this has one to ask
Topic, due to the characteristic of colored paint, the position of eye-observation measuring cup scale gage determines that the volume accuracy of measurement of color masterbatch is not achieved required 0.1
Measuring cup volume when the precision, especially a large amount of tinters of gram weight also will be big, and the sectional area of measuring cup is bigger, and human eye determines color
The error whether mother reaches defined amount cursor position is bigger, and 0.1 gram of toning required precision is not achieved at all.It and is exactly not smart
Quasi- volume mix colours manually method also compared with weight ratio toning method in actual operation than it is difficult and much cumbersome so that cannot be real
Now effectively toning color matching；Imagine 2: using hydrometer jar method: because the discontinuity of the wall built-up residual and volume metering of color masterbatch, obtains
It is also to be difficult to realize in practical application to required volume；Imagine 3: hand injection pipe volume measurement outpours method: due to extracting color
Color masterbatch lanyard at female injecting adaptor, can cause trueness error, and it is not only bothersome but also not environmentally to remove lanyard color masterbatch, if not clearing up
Injector head exit, which can be flowed to, influences 0.1 gram of error guarantee below.Equally, it outpours sticky color masterbatch manually to exert oneself very much, strength
Small people even pushes away motionless, and although the caliber for reducing injection-tube can be reduced outpours power, improves the release precision of single, but for amount
Big color masterbatch accurately outpours and needs to carry out in multiple suction color masterbatch container the extraction of color masterbatch, and injection will be removed every time by extracting
Lanyard color masterbatch at nozzle, and the increase of number will increase accumulated error, 0.1 gram of error is more difficult to control at this time, and
Complicated too many than weight ratio method used at present is matched colors in this way, color matching industry can select the weight simply easily realized certainly
It matches colors than method, is difficult to ensure that this volume ratio method of precision is mixed colours without selecting i.e. bothersome.
Technical staff in the industry does not just consider further that after the appearance of weight ratio color matching method to go to realize with volume ratio
Color matching.Because till now from the past, occurrences in human life assert that it cannot replace weight ratio tune after above-mentioned each analysis of Influential Factors in the industry
Color and color matching, this is to have become a kind of technology prejudice in the brain of subtle occurrences in human life in the field of business.
Summary of the invention
Automobile coating repairing has had more than 100 years history, is matched colors with weight ratio.It is not smart to be primarily due to volume measurement
Really, the equipment after release is unable to meet demand, and external one stream manufacturer attempts also solve this problem for a long time, and people are general
All over thinking that automobile coating can only be measured with weight ratio.Automobile coating repairing is also to record in this way in well-known technique.For example, car paint,
Wang Minxin, Wang Lijun write, and clearly refer in the allotment of Chemical Industry Press's -7.6.3 car repair push-and-pull finishing coat color in 2005
It is weighed out using electronic balance to coating, pigmented finiss wants more batches of a small amount of additions, materials is avoided excessively, every time first to go to apply on a small quantity
Material configuration waits and allots colored paint exact matching, further according to needing exaggerated scale.It can be seen that this is general knowledge known in this field, people are caused
Technology prejudice is formd, can not expect using volume ratio counterweight.
In order to solve technology prejudice, the car refinishing paint bulking value mixing that the present invention provides a kind of accurate proportion color masterbatch is adjusted
