Description
Technical field
The present invention relates to a kind of method judging material illumination, particularly relate to the determination methods of latex paint trend of illumination intensity of film.
Background technology
As everyone knows, the daylighting quality in house directly affects the sensory experience in house to a certain extent, the house that daylighting is good generally can be visually more spacious, but daylighting environment is people be difficult to change a parameter index, if therefore can have a kind of coating can by limited daylighting can at utmost utilize by room, just can improve the visual effect in house.Can judge that this coating is assessed the ability improving house visual effect to the illumination photometry of coating film.If carry out the standard test system of illumination photometry with existing illumination proving installation, but this experimentation is complicated, need a large amount of manpower and materials and time.
Summary of the invention
The object of the present invention is to provide the method judging trend of illumination intensity of film fast, so that carry out estimating of illumination, reduce experiment consuming time.
The method of quick judgement trend of illumination intensity of film provided by the invention, comprises the following steps:
Steps A, modulates the sample paint of this film, and tests lightness and the illumination of this sample paint, determines the relation of lightness and illumination according to many group lightness and illumination data;
Step B, tests the lightness of this film, and judges trend of illumination intensity of film according to described relation.
Described method, wherein, steps A comprises the following steps:
Step one, at least three sample paints of modulation film;
Step 2, is uniformly coated in art post paperboard by each sample paint film applicator, each sample paint preparation at least three art post paperboards, for subsequent use after its drying;
Step 3, sample paint spectrophotometer dried in step 2 is carried out lightness test, in art post paperboard, at least three diverse locations of sample paint respectively get a point respectively, carry out the test of lightness, carry out same operation to the sample paint in these at least three art post paperboards;
Step 4, by each sample paint gained at least 9 data preparations in step 3, removes a mxm., removes a minimum, draw a mean value according to all the other at least 7 data, as the actual lightness of this sample;
Step 5, adopts illumination proving installation to draw the actual illumination of each sample;
Step 6, according to actual illumination and the actual lightness of each sample, draws typical curve, and extrapolates theoretical calculation formula one, Y=F(X), wherein Y is illumination, and X is lightness mean value, F(X) be the function of X;
Step 7, the lightness mean value of the more Multi-example paint of this film and actual illumination is tested according to step one to step 5, and lightness mean value is introduced the formula one in step 6, draw theoretical illumination, difference mean value according to theoretical illumination and actual illumination obtains correction factor f, and substitute into formula one and draw formula two, Y=F(X) ± f;
In described step B, measure the lightness of film and judge this trend of illumination intensity of film according to formula two.
Described method, wherein, the papery of art post paperboard is identical with illumination proving installation papery used.
Described method, wherein, in step 2, film applicator is 150 μ film applicators, art post paperboard 23 ± 2 DEG C, place under the dry environment of 50%RH until paint film is done solid work completely is as the criterion.
Described method, wherein, in step 6, in order to show that the data of theoretical calculation formula one are no less than 20 groups of actual lightness of sample paint and actual illumination data.
Described method, wherein, in order to show that the data of correction factor are no less than 20 groups of actual lightness of sample paint and actual illumination data.
Principle of the present invention is based on: the illumination luminous flux that to be receiving surface send luminophor and the luminous flux sum that reflective surface sends; Lightness is eyes to the sensation of the bright-dark degree of light source and body surface, and lightness is decided by the reflection coefficient of the intensity of light source and the body surface thrown light on.So conceptually, these two optical parametrics are relatively, lightness can consider index as illumination.Due to simple to the test of lightness, therefore the present invention avoids a time waste carrying out illumination experimentally to each sample, and the method calculates to obtain computing formula by mass data, and method is reliable, infer sample illumination to preliminary, reduce unnecessary experimental period loss and have a far reaching influence.
Embodiment
Step 1: according to latex paint manufacture craft, according to the formula of design, carries out formula and makes under the homo-mixer of regulatory specifications, filling, for subsequent use.
Step 2: with 150 μ wet film preparing devices by the sample film in step 1 on the art post paperboard sheet of 15*12, exist side by side and be placed in 23 ± 2 DEG C by the scraps of paper, maintain under 50%RH environment to the scraps of paper and do solid work completely (>1h), each sample preparation 3 scraps of paper.
Step 3: the scraps of paper dried in step 2 are carried out lightness test on color-eye7000A spectrophotometer (commercially available prod), record lightness data, often open paperboard and get each 1 point in position, paint film upper, middle and lower totally 3 points respectively, 3 sample paper carry out same operation.
Step 4: arranged by 9 numerical value of sample gained each in step 3, remove a mxm., remove a minimum, other 7 data draw a lightness mean value.
Step 5: adopt illumination test box (commercially available prod) each sample to be carried out to the test of illumination, draw the brightness value of sample.
Step 6: the lightness of gained in above-mentioned steps and brightness value data are drawn typical curve and correlation formula (sample number >=20 data), such as, obtain formula (): Y=652.33X-61213;
Step 7: the brightness value testing other 20 samples by the method for above-mentioned test lightness, is inserted in formula in step 6 (), records compared with brightness value, draw 20 differences by gained brightness value with actual.Because the luminosity equation observed in step 6 finds that lightness often changes 0.1, illumination change is no more than 50, and has two to be greater than 50 in 20 differences in step 7, and all the other 18 all in scope, get the mean value of this 18 number, obtain correction factor (gained correction factor f=27).
In the aforementioned embodiment, even roughness paint film state can obtain comparatively stable illumination data, and the brightness value of each point of even roughness paint film is less relative to the deviation of average illumination.
Illumination can be made with comparatively meal material obviously to decline as CC500, cause lightness and illumination relational expression to be false.
On illumination impact clearly, the previous embodiment scope of application is at PVC40-45% and a little more than applicable in the formula of cPVC for PVC material.
Owing to considering that part latex paint product has the xanthochromia problems such as weatherability, therefore the test of this sample lightness and illumination is completed, to reduce the error produced due to this life of product xanthochromia as far as possible within the relatively close time.
