Description

[0001]
[Industrial application fields]
The present invention relates to a method for continuously measuring torque of an adhesive sample and an apparatus therefor, for example, to a continuous measurement method and apparatus capable of continuously measuring physical properties such as viscoelasticity of rubber and similar materials.
[0002]
[Prior art]
Conventionally, for example, a continuous measurement device that measures physical properties such as viscoelasticity of rubber and similar materials is used in a sample chamber configured by closing a heating plate having a rotation mechanism and a heating plate having a torque detection mechanism. When the sample is closed and heated, and the heating plate having one rotation mechanism is rotated, the torque generated in the heating plate having the other torque detection mechanism is detected to complete the measurement. After the measurement is completed, the test-completed sample is discharged from the data chamber, the next sample is supplied, and a large number of samples are continuously measured one after another.
In this case, the first problem is how to smoothly remove the adhesive sample from the data chamber after the test is completed.
[0003]
As a conventional device of this type, a device that applies a vibration torque with a minute angle of ± (plus / minus) 0.1 ±± 1 °, at most ± 5 °, to the rotating-side hot platen is disclosed in JP-A-6-109620. It is disclosed in the gazette.
In this conventional apparatus, a sample is sandwiched between two films and confined between two heating plates, and ± (plus / minus) 0.1 to ± 1 °, and at most ± 5 ° on the rotating heating plate. When a vibration torque of a slight angle is applied, the torque transmitted to the other hot platen through the sample is measured, and the sample after the test is peeled off from both hot plates while sticking between the two upper and lower films. And discharged from the sample chamber.
In this case, the two films can resist torsional deformation due to relative rotation of the two hot plates, are non-adhesive to the hot plate, have thermal characteristics that can withstand heating, and the film has 2 It is necessary to satisfy such requirements as being sufficiently flexible and stretchable to accurately match the surface shape of a single hot platen, and the selection of films that meet these requirements is essentially an experimental matter. Yes, a polyester film of 10 to 50 μm, 15 to 30 μm, particularly 20 to 25 μm, particularly a polyester film made of polyethylene terephthalate is suitable. When such a preferable film is used, the film is placed in the sample chamber. Even if present as a lining, in most cases the results are not significantly altered compared to the absence of film.
[0004]
[Problems to be solved by the invention]
In the above-mentioned conventional apparatus, when the rotation angle of the rotating hot platen is as large as 90 ° or more, the film that is sandwiched between the rotating hot plate and the sample and rotates integrally with the rotating hot plate is twisted. Since the deformation cannot be countered, it is torn off and the sample cannot be covered, the sample comes into contact with the hot platen and becomes difficult to peel off. Alternatively, if the film that rotates integrally with the rotating side heating plate is strong and cannot be torn, it rotates integrally with the rotating heating plate and draws the continuous part of the surrounding film to create slack, so the heating plate is opened after measurement. In this case, only the film in contact with the rotating side heating plate becomes loose, and it is difficult to put the sample between the film on the torque detection side and discharge it. In addition, the pulling resistance force that tries to prevent the rotation generated in the film greatly affects the rotating hot platen, greatly affects the torque measurement, and the accurate torque measurement cannot be performed.
[0005]
Moreover, the means for sandwiching the sample between the two films and supplying them between the hot plates is troublesome.
That is, for example, if an attempt is made to place a sample on the lower film, the upper film becomes an obstacle, so the sample is placed on the lower film with the upper and lower films spread, and then the upper film is In order to accurately place the sample on the test position with the film covered from above, a means for opening and closing the upper film in conjunction with the upper and lower films is required, and the apparatus is considerably complicated and the operation is troublesome. It is. In addition, after the test is sandwiched between two films, when the sample is discharged from the test chamber while being sandwiched between the two films, the next sample is sandwiched between the two films by the discharge movement of a certain distance. It is necessary to supply to the test position as much as possible. To do this, it is necessary to supply a plurality of samples to the test position sequentially between two films at an accurate interval. It is considerably difficult to realize that the sample is not supplied by being fixed to the upper and lower films while being sandwiched.
[0006]
[Means for Solving the Problems]

Since the torque can be measured by closing the heating plate and smoothly rotating the heating plate on the rotating side without being interrupted by the film, the rotating plate is rotated twice (720 °). Even if the rotation angle is 90 ° or more, the rotating platen on the rotating side is in close contact with the sample and rotates integrally, and the sampler on the torque detection side supports the sample integrally through the film with little rotation. Torque can be detected reliably, and after the measurement is completed, the film is fixed on the heat plate on the torque detection side, and the sample plate is opened when the sample plate is opened by opening the heat plate.

The sample after measurement can be reliably discharged.
[0009]
In addition, the film that has been subjected to surface treatment for sample adhesion is made of a film that has been subjected to rough surface treatment such as sandblasting on the film surface on which the sample is to be placed.

It is possible to measure the torque by closing the heating plate and smoothly rotating the heating plate on the rotating side without being obstructed by other films or the like. Even if the rotation angle is as large as 90 ° or more, the rotating hot platen is in close contact with the sample and rotates integrally with the sample, and the torque detecting hot platen hardly rotates. The sample can be supported in a single piece through and the torque can be detected reliably.After the measurement, the film is fixed on the torque detection side heating plate, the heating plate is opened, and the sample chamber is opened.

Therefore, even when the rotating side hot platen is rotated greatly, the rotating side hot plate is in close contact with the sample and rotates integrally with the sample, and the torque detecting side hot platen is inserted through the film. Torque can be detected reliably by supporting the sample integrally. After the measurement, the film is fixed on the heat plate on the torque detection side, and the sample plate is released when the sample plate is opened by opening the heat plate. Is it a hot platen on the rotating side coated with an agent? The sample is peeled off smoothly and easily, and the sample is left on the heating plate on the torque detection side. The sample is discharged out of the sample chamber together with the film by discharging the film out of the sample chamber. In the following, there is an effect that it is possible to enable continuous measurement in sequence.
