Description
Technical Field
The invention relates to the technical field of paint performance testing, in particular to an automatic determination device and a determination method for drying time of a non-sticky tire of a road marking paint.
Background
The road marking paint is one of the most common road traffic marking materials, is applied to the road surface in a certain construction mode to form a marking, plays the roles of separating lanes and warning drivers, and thus achieves the purpose of reducing traffic accidents. The performance of the pavement marking paint not only affects the road maintenance and maintenance cost, but also directly affects the traffic safety. Therefore, after the road traffic marking is formed by construction of the road marking paint, the road traffic marking usually meets the performance requirements of bright marking effect, strong adhesion, good durability, short construction drying time, skid resistance and the like.
The requirement of construction drying time is determined by the non-intermittence of road traffic, and particularly, the faster the construction time of road traffic marking is, the smaller the influence of traffic jam is. According to the different types of road pavement marking paint, the drying time of the non-sticky tire is generally required to be 3-35 min. The test and detection of the drying time of the non-sticky tire is a main technical means for ensuring that the quality of the non-sticky tire meets the requirements. In chapter vi of pavement marking paint (JT/T280-2004), the third test method for solvent-based, two-component, and water-based pavement marking paints was specified, and the measurement of tack-free drying time was carried out using a tack-free time measuring instrument.
The procedure of this test was: in the test, a stopwatch is pressed for timing, the actual measurement is started when the ordinary marking paint is 10min, and the actual measurement is started when the reflective marking paint is 5 min; during actual measurement, the non-tire-sticking time measuring instrument is held by a hand to roll on the coating plate, whether a test material is stuck on the non-tire-sticking time measuring instrument or not is observed, if the test material is stuck, the tire is wiped by cotton cloth wetted by acetone or methyl ethyl ketone immediately, the test is repeated every 30s, and the stopwatch is stopped to time until the tire of the non-tire-sticking time measuring instrument is not stuck with the test material, and the time is the 'non-tire-sticking time' of the test material.
The operational points in the test are as follows:
(1) when the tire-sticking-free time measuring instrument is rolled, the handles are lightly held by two hands, so that the condition that any force except the dead weight of the instrument is added on a coating film to cause inaccurate test results is avoided.
(2) In the experiment, need two test personnel at least to cooperate, alone operate not glutinous child time measurement appearance, another person operates the stopwatch to make the timing more accurate.
The manual hand-held operation is difficult to avoid the pressure of both hands from being applied to the coating film, and in the test, the coating film is frequently required to be repeatedly rolled for dozens of times, so that the requirement on the operation of a tester is high, the physical consumption is large, and the test result is easy to be inaccurate; a single person cannot test, more than two testers are needed to be matched, more human resources are needed to be consumed, and the cost of the test is increased.
