Specific embodiment
A kind of sample preparation device of accurate control water-repellent paint coating thickness, including coating work platform, smooth scraper and thickness
Stylus.
1, coating work platform
Coating work platform is made of glass plate, polyfluortetraethylene plate, laminate, air level.
Glass plate, polyfluortetraethylene plate constitute working plate.Glass plate guarantees that workbench is smooth, stablizes, directly and coating
The polyfluortetraethylene plate of contact guarantees the smooth easy mold release of device.
For requirements of the national standard multi-component coating primary coating to specific thickness, one-component coating divides three-layer coating to regulation thickness
Degree.For can make coating reach not only can disposably coat but also can point three-layer coating, spy invents ladder-like rectangle frame stainless steel layer pressure
Plate.After the activated processing of polyfluortetraethylene plate, stainless steel layer pressing plate is stepped to be connected to polyfluortetraethylene plate top.Standard is wanted
Final coating thickness 1.5mm ± 0.2mm is sought, therefore the height that every layer of the laminate of stainless steel is arranged is 0.5mm, thus can
Meet 0.5mm, 1.0mm, 1.5mm with the coating requirement of 0.5mm uniform increments.In view of the contraction after coating coating, and configure
Two sets of every layer heights are respectively the laminate of 0.6mm, 0.7mm.Laminate sheet material select with coating soap-free emulsion polymeization, do not react
Stainless steel is durable.
Fluent material is affected by gravity larger, and operating process slightly tilts, and will result in final water-repellent paint and applies film thickness
Degree is uneven.Therefore, special that universal circle bubble is installed on device, using it is preceding it is ensured that work top level.
2, smooth scraper
To make water-repellent paint coated side uniform ground, fully considers stress form in coating procedure, use common spatula list
Hand operation, intermediate stress is excessive, and film is easy to appear intermediate thin, the phenomenon of both sides thickness.The special smooth scraper of the device, using with
The stainless steel of the identical material of laminate is made, and every set coating work platform configuration 3 is smooth scraper, two convex shape scrapers, one
Rectangle scraper.0.5mm, 1.0mm coating thickness use convex shape scraper, and chimb height is 0.5mm, and 0.5mm coating thickness makes
The chimb length of convex shape scraper is greater than laminate bottom Opening length and is less than time lower opening length, 1.0mm film
The chimb length for the convex shape scraper that thickness uses is greater than laminate time lower opening length and is less than the top Opening length,
1.5mm coating thickness uses rectangle scraper, and the length of rectangle scraper is greater than laminate the top Opening length, guarantees the flat of coating
Whole property.Similar, 0.6mm, 0.7mm layers of high laminate respectively configure the 3 smooth scrapers respective depth.
3, thickness stylus
Thickness stylus is that scale is identified on the stainless pin not with paint adhesion, and paint thickness is measured after coating, is realized
The science of quality, thickness dual control, the key index of further Control experiment process, guarantee test result is accurate.Different-thickness layer
Pressing plate prepares 3 different steel needles, identifies 0.5mm, 1.0mm, 1.5mm respectively；0.6mm,1.2mm,1.8mm；0.7mm,
1.4mm,2.1mm.It is corresponding with 0.5mm, 0.6mm, 0.7mm layers high laminate to use.
Since water-repellent paint specification type is more, the utility model is referred to the higher standard " polyurethane water-proof of frequency
Coating " GB/T 19250-2013, " Test methods for building waterproof coatings " GB/T 16777-2008 be illustrated.According to inhomogeneity
The shrinkage of type coating designs and produces three sets of sample preparation devices, carries out specific embodiment party below as 0.5mm layers high bushing device
The explanation of method, 0.6mm, 0.7mm layers high bushing device coating method are tested referring to 0.5mm bushing device embodiment.
1, before sample preparation, sample and test tool used should be placed at least for 24 hours under standard test conditions.
2, according to water-repellent paint property, state, shrinking percentage, the sample preparation device of a set of suitable thickness is selected.
3, coating work platform is placed on smooth stable rigid plane, whether observes circle air level in central location,
Coating work platform is adjusted, guarantees that coating work platform is horizontal positioned.
4, under standard test conditions, weigh the coating of required test mass, guarantee final coating thickness 1.5mm ±
0.2mm。
Sample mixed after placement is uniform, diluent must not be added.
If sample is multi-component coating, after the match ratio mixing wanted by production enterprise the case where not being mixed into bubble
Under be sufficiently stirred 5min, stand 2min, disposably pour into the model frame of stainless steel layer pressing plate composition, use the smooth scraper of rectangle
The bubble for gently scraping off surface measures thickness using thickness stylus, guarantees that its thickness meets the requirements, finally strike off surface.
If sample is one-component coating, (every minor tick is no more than for 24 hours) is coated in three times.Coating 0.5mm for the first time, interval
5 minutes, the bubble on surface is gently scraped off using the smooth scraper of 0.5mm convex shape, measures thickness using thickness stylus, guarantees its thickness
Degree meets the requirements.Second of coating 1.0mm, is spaced 5 minutes, the gas on surface is gently scraped off using the smooth scraper of 1.0mm convex shape
Bubble measures thickness using thickness stylus, guarantees that its thickness meets the requirements.Last time coating is spaced 5 minutes to 1.5mm, uses square
The smooth scraper of shape gently scrapes off the bubble on surface, measures thickness using thickness stylus, guarantees that its thickness meets the requirements, finally by table
Face strikes off.
5,96h is conserved under the film standard test conditions prepared, then demoulding, continued after film turn-over in code test item
72h is conserved under part.
6, by using this device, by being largely film-made test, the coating thickness of coating be can be effectively controlled in 1.5mm
Within the scope of ± 0.2mm.
