Description
Technical field
The present invention relates to a kind of floating force detection method, especially relate to the detection method of a kind of leafing-type aluminium powder slurry floating force.
Background technology
The detection method of current leafing-type aluminium powder slurry floating force is under 23 ± 2 DEG C of room temperatures, previously prepared good coumarone indene resin solution is starched with leafing-type aluminium powder and mixes, move in test tube, bottom potpourri in steel disc insertion test tube, steel disc is proposed, measure the total length of steel disc immersion and the length of floating, the ratio of the length of floating and the total length of immersion is multiplied by 100 again and is floating force.Floating force >=80% is certified products.
With the floating force that the method measures, aluminum paste " of short duration " floating force under this specified conditions can only be described, some record the qualified aluminum paste of floating force thus, the aluminium paint made with it is at room temperature stored and is just lost floating force in about one month, the obfuscation of its paint film burnt hair does not have metallic luster, and therefore traditional detection method really can not embody the quality of leafing-type aluminium powder slurry.In actual applications, the quality that " for a long time " floating force could really embody leafing-type aluminium powder and starch, this is also required for client.
Summary of the invention
Object of the present invention is exactly the detection method providing a kind of simple to operate, measurement result leafing-type aluminium powder slurry floating force accurately in order to overcome defect that above-mentioned traditional detection method exists.
Object of the present invention can be achieved through the following technical solutions:
A detection method for leafing-type aluminium powder slurry floating force, the method comprises the following steps:
(1) leafing-type aluminium powder slurry to be measured is mixed with special paint vehicle, make mill base, be placed in the clean iron flask of 200ml, sealed tank cap;
(2), after step (1) gained mill base being placed in the thermostatic drying chamber maintenance 70 ~ 74h of 55 ± 2 DEG C, taking out and be cooled to 23 ± 2 DEG C;
(3) mill base after step (2) being processed brushes preparation three pieces of test plate (panel)s;
(4) three pieces of test plate (panel)s that step (3) is obtained being placed in temperature is 23 ± 2 DEG C, relative humidity be 50% ± 5% thermostatic constant wet chamber keep flat 10 minutes after, check test plate (panel), when aluminium powder paint film at least two pieces of test plate (panel)s presents the aluminium powder metal film of more than 90% (containing 90%), then the floating force of leafing-type aluminium powder slurry to be measured is qualified, when being less than the aluminium powder paint film on two pieces of test plate (panel)s and presenting the aluminium powder metal film of more than 90% (containing 90%), then the floating force of leafing-type aluminium powder slurry to be measured is defective.
Described leafing-type aluminium powder slurry to be measured is 1: 5 with the mass ratio of special paint vehicle.
Leafing-type aluminium powder to be measured is starched the method mixed with special paint vehicle is: first starched by leafing-type aluminium powder to be measured and be uniformly dispersed with the special paint vehicle of equal in quality, then added by remaining special paint vehicle, and stir.
The method of the mill base brushing preparation three pieces of test plate (panel)s described in step (3) is the spread coating in the general preparation method of GB/T1727-1992 paint film.
Described special paint vehicle is made up of the raw material of following component and weight portion: linseed oil 20, terebinthina 32, petroleum resin 48.
The preparation method of described special paint vehicle is as follows: be dissolved in terebinthina at 90 DEG C of temperature by petroleum resin, linseed oil being no more than, be cooled to room temperature for subsequent use, adds the amount that a small amount of terebinthina runs off to offset turpentine oil volatile in course of dissolution.
Iodine value >=the 175gI/100g of described linseed oil, acid value≤4mgKOH/g, color and luster≤No. 10 that linseed oil adopts iron-cobalt method to record.
Described terebinthine boiling range is 150 ~ 190 DEG C, and refraction index (20 DEG C) is 1.4670 ~ 1.4780.
The softening point of described petroleum resin is 110 ~ 120 DEG C, color and luster≤No. 10 that petroleum resin adopt iron-cobalt method to record.
The detection method of existing leafing-type aluminium powder slurry floating force really can not embody the quality of leafing-type aluminium powder slurry.Leafing-type aluminium powder slurry is mainly for the production of leafing-type aluminium powder paint, detect that portioned product that floating force is qualified is often after making aluminium paint by existing method, store the paint film made less than month and just become grey dimmed, lose the due metallic luster of leafing-type aluminium powder paint completely, method of the present invention is that leafing-type aluminium powder slurry is made mill base, 70 ~ 74h is placed in the constant temperature oven of 55 ± 2 DEG C, this is the process of an accelerated test, the auxiliary agent (as stearic acid) that the leafing-type aluminium powder of high-quality starches its coating is be not easy to be lost protective effect by dissolving in accelerated test process, permanent floating force can be kept.Detect after qualified aluminum paste makes paint by the method, at room temperature store the paint film made after a year and still can keep good metallic luster, and detect underproof aluminum paste by the method, even if there is excellent floating force, the aluminium paint made with it was room temperature storage about month, and its paint film just starts to lose due metallic luster.
Compared with prior art, the present invention has the following advantages and beneficial effect:
(1) method of the present invention is simple, convenient, needed raw material and equipment cost lower;
(2) the inventive method testing result is accurate: detect after qualified leafing-type aluminium powder slurry makes paint by the inventive method, at room temperature store the paint film made after a year and still can keep good metallic luster;
(3) method of the present invention has applicability and practicality widely.
