Description
Technical field
The invention belongs to building and furnishing fields, drill except aldehyde effect particularly to a kind of formaldehyde removing coating paint film
Show method.
Background technology
The emulsion paint laying claim to anti-formaldehyde functional effect that China is commercially available at present, is both needed to meet China's people's republicanism
State's building material industry standard: the rule in function of purifying indoor air coating material purifying property JC/T1074-2008
Fixed.Wherein purifying formaldehyde rate at least to reach 75%, and the lasting purifying rate of formaldehyde at least to reach 60% can.But
Existing method needs the closing space at a cubic metre to test, and needs the testing time of more than 7 days,
Calculating with spectrophotography afterwards, this is detrimental to quickly demonstrate it in showroom to consumer and lays claim to except aldehyde merit
Can coating except aldehyde effect.
Summary of the invention
It is an object of the invention to provide a kind of formaldehyde removing coating paint film and remove aldehyde effect demenstration method, it can
Whether quickly displaying coating directly perceived has except aldehyde effect.
The present invention is achieved in that a kind of formaldehyde removing coating paint film removes aldehyde effect demenstration method, including such as
Under step:
(1), model to be measured is prepared: weigh coating to be measured and distilled water respectively with electronic scale according to 90-110:
The ratio of weight and number mix homogeneously of 10-30, then brushes on sample board uniformly by mixture；Two hours
Rear brushing second time, pastes above by filter paper, at ambient temperature when paint film is moistening after brushing
Coating makes coating make model to be measured after drying from dry or heating；
(2), with dropper pipette Potassium metaperiodate. reagent two to three droplet and glued above embedding filter paper in model to be measured,
Pipette stand-by formaldehyde diluent two to three droplet with another dropper more afterwards and glued embedding in model to be measured
Filter paper above, then cover filter paper completely with sheet glass；
(3), cover sheet glass and open sheet glass after 3-10 minute, pipette 4-amino-3-hydrazine-5-with dropper
Sulfydryl-1,2,4-triazole reagent two to three drip and are glued above embedding filter paper in model to be measured, observe filter
Color change on paper, if filter paper invariant color, coating to be measured is to have except the coating of aldehyde function, if filter paper becomes
Color coating the most to be measured is not have except the coating of aldehyde function.
Prioritization scheme is further: described model to be measured comprises at least two groups, and at least a part of which one group is for being used for being coated with
Brushing tool has the detection of the coating except aldehyde function model to be measured, at least another group not to have except aldehyde for being used for brushing
The comparison of the coating of function model to be measured.
Prioritization scheme is further: described filter paper sticks in sample according to the size of sample board by parallel matrix form
Distance >=4cm on plate, between filter paper.
Prioritization scheme is further: described sheet glass is more than filter paper, and the length × width x thickness of sheet glass is
50-70mm×50-70mm×2-4mm。
Formaldehyde removing coating paint film of the present invention has the following advantages except aldehyde effect demenstration method: demonstration of the present invention
The chemical reaction of method is based on AHMT method survey formaldehyde: AHMT method formaldehyde and AHMT (4-amino-3-hydrazine-5-
Sulfydryl-1,2,4-triazoles) it is condensed in the basic conditions, it is oxidized to aubergine compound through Potassium metaperiodate.,
Then the method [13] of colorimetric assay detection content of formaldehyde, this method specificity and selectivity are all preferable, greatly
Not interference measurement when the amount aldehyde material such as acetaldehyde, propionic aldehyde, butyraldehyde, hyacinthin coexists, detection is limited to 0.04mg/L.
By the demenstration method of the present invention, can show to have by the change contrast of color within ten minutes and remove
Aldehyde functional paint paint film except aldehyde effect, can give client quickly and intuitively to demonstrate, and then strengthening to tool
There is the understanding of function except aldehyde effect coating, be beneficial to displaying of marketing.
