Test Methods9.1 Solids Content:9.1.1 Place approximately 20 g of the adhesive in a coveredweighing bottle.9.1.2 Weigh a small aluminum foil drying dish together witha small glass stirri
18、ng rod to the nearest 1 mg. Weigh out to thenearest 1 mg approximately 112 g of the adhesive by differencefrom the weighing bottle into the dish, keeping the bottlecovered as much as possible. Distribute the adhesive uniformlyover the bottom of the dish in as thin a layer as possible bymeans of the
19、stirring rod.9.1.3 Place the dish with the rod and contents in a circulat-ing air oven at 105 6 2C (221 6 3.6F) for 3 h 6 5 min oruntil a constant weight is reached.9.1.4 Place the warm dish with rod and contents immedi-ately into a desiccator and allow to cool to room temperaturebefore weighing to
20、the nearest 1 mg.9.1.5 Calculate the percent solids content as follows:Solids content, % 5 Wr/Ws! 3 100 (1)where:Wr= weight of residue, g, andWs= weight of specimen, g.9.2 Viscosity and Shear Ratio:9.2.1 ViscosityDetermine the Brookfield viscosity of thematerial at 23 6 2C (73.4 6 3.6F) in accordanc
21、e withMethod B of Test Methods D 1084. Use Brookfield Viscometerwith the helipath stand and TA, TB, TC, TD, or TE spindles at5 rpm. Record viscosity in mPa.s (cP).9.2.2 Shear RatioWith the spindle used for the viscositydetermination, measure the viscosity of the material at 2.5 rpm;and then at 0.5 r

23、est chart using a film applicator.Test lubricating life by rubbing finger on coated chart at 30-minintervals. Record lubricating life as the time at which drag orfriction increases noticeably and material starts to thicken orbecome tacky.9.4 SagApply a 0.75 6 0.01-mm (0.030 6 0.004-in.)thick film of
24、 material to a glass plate or smooth-surface papertest chart in the manner as described in 9.3. Support glass plateor chart vertically with the 150-mm (6-in.) axis of the striphorizontal. After 1 h, check for sagging or running.9.5 Since a precision estimate for this test has not beendeveloped, this
25、 test method is to be used for research orinformational purposes only. Therefore, this test should not beused for acceptance or rejection of a material for purchasingpurposes.9.6 Peel Strength Test:9.6.1 Roughen one side of a 25-mm (1-in.) rubber strip witha coarse grinding wheel or other suitable m
26、eans. Apply a brushcoat of the freshly mixed lubricant adhesive to the roughenedsurface of the rubber strip and to the concrete block surface.9.6.2 Immediately place the coated surfaces together androll down the rubber strip with a 50-mm (2-in.) steel rollerweighing 4.5 kg (10 lb), making six single
27、 passes, each passrequiring about 2 s. Wipe excess material away from the edgesof the rubber strip. Place the 50 mm (2 in.) wide side of thesteel block on the strip. Cure specimen for 48 h.9.6.3 After curing, remove the steel block. Separate about25 mm (1 in.) of an end of the rubber strip from the
28、concrete.Support the specimen with the surface of the concrete block towhich the rubber strip is attached horizontal and facingdownward. Suspend a 500-g weight from the free end of therubber strip for 3 min. Remove the weight and carefullymeasure to the nearest 1 mm (116 in.), the distance the rubbe
29、rstrip was peeled from the concrete. Repeat using the 1000-gweight.9.6.4 Report results in millimetres (or inches or fractionthereof) peeled in 3 min. Should the specimen peel completelyin less than 3 min, report as 100 % peeled and record the time.9.6.5 Since a precision estimate for this standard
30、has notbeen developed, this test method is to be used for research orinformational purposes only. Therefore, this test should not beused for acceptance or rejection of a material for purchasingpurposes.10.
