加工による経験的判断しか方法はなく、粘着性を
定量的に評価できる試験方法はなかつた。 When a molding material is subjected to roll processing, extrusion, injection molding, etc., the molding material becomes semi-molten or molten due to conduction heat from the roll wall or cylinder wall and shear friction heat between the wall surface and the material. The molding material in a semi-molten or molten state is more or less sticky to the metallic roll surface or cylinder wall and screw surface.
If the adhesiveness is moderate, it is desirable to improve the penetration between the rolls or between the cylinder and the screw, and to effectively knead the molding material. However, if the adhesiveness of the molding material is extremely low, the roll Slips will occur on the surface, cylinder surface, screw surface, and the kneading will be reduced.On the other hand, if the viscosity of the molding material is too high, the torque applied to the rolls or screws, etc. will increase, which increases accordingly. A large amount of power is required, and if the torque becomes abnormally large, the amount of heat generated by friction becomes large, and the temperature of the molding material becomes abnormally high, causing seizure or decomposition. However, in the past, the only way to determine the adhesion between a molding material and a metal surface was to make an empirical judgment based on actual roll processing, extrusion, or injection molding, and there was no test method that could quantitatively evaluate the adhesion.

るための指針が得られるものである。 In the present invention, since two disks facing each other are heated, the tackiness can be measured by changing the temperature of the upper disk and the lower disk separately.The molding material is placed on the upper surface of the lower disk, and the The molding material is pressurized by lowering the disc, so by adjusting the amount of descent of the upper disc, the distance between the upper and lower discs can be changed and the amount of molding material placed can be changed. However, since the torque applied to the upper disk is measured, by changing the rotation speed of the lower disk, changes in torque due to fluctuations in rotation speed can be measured. Therefore, the torque due to the adhesiveness of the molding material can be measured by It can quantitatively measure the relationship between the gap and temperature of the two discs, the amount of molding material placed, and the rotational speed of the lower disc.Furthermore, it is equipped with a torsion load cell that measures the rotational load in the horizontal direction of the pressurizing ram. Attach an axial pressure load cell to the pressurizing ram to measure the load in the axial direction of the pressurizing ram,
The molding material was placed on the upper surface of the lower disk, the upper disk was lowered to pressurize the molding material, and the load on the upper disk was measured by each load cell while the lower disk was rotating. It is possible to measure the load applied to the torsional load cell and axial pressure load cell by lowering it to apply pressure to the molding material and rotating the lower disk in the horizontal direction, and measuring the relationship between the magnitude of surface pressure applied to the molding material and tackiness. It is also possible to do so. Therefore, it is possible to experimentally evaluate the degree of difficulty in roll biting and screw biting in actual roll processing, extrusion, injection molding, etc., and to determine processing conditions that will improve roll biting and screw biting. It provides guidance.

To measure tackiness, in the measuring device shown in FIG. Both were set at 110° C., and the position of the stopper fixture 25 was adjusted so that the gap between the upper and lower disks 1 and 2 was 2.5 mm. Next, adjust the variable transmission 33 so that the lower disc 2 is at 1.
It was set to rotate at rpm, and a load applying device (not shown) was adjusted so that a pressure of 100 Kg/cm 2 could be applied to the upper disk 1. The phenolic resin molding material was weighed and placed on the upper surface 14 of the lower disc 2, and the load applying device was driven to lower the upper disc 1, thereby pressurizing the phenolic resin molding material. At the same time, the motor 34 was driven to rotate and the load applied to the torsion load cell 17 was measured and recorded. The measured torque value remained constant for a while after the start of the measurement, and eventually began to increase due to the curing reaction of the phenol resin, but the measurement was completed at that point. Next, the variable transmission 33 is adjusted so that the lower disc 2 is set to 2r.pm4r.p.

This is a curve obtained by calculation from the results. From the difference between torque value A and torque value B at the same rotation speed, it was possible to measure the increase in torque due to the stickiness of the phenolic resin molding material to the disk surface.

きた。 In the measuring device shown in Fig. 2, the temperature of the upper disk 1 is set to 90℃, the temperature of the lower disk 2 is set to 120℃,
The position of the topper fixture 25 was adjusted so that the gap between the upper and lower disks 1 and 2 was 0.5 mm. Lower disk 2
It was set to rotate at 6 rpm, and the load applying device was adjusted so that a pressure of 100 Kg/cm 2 could be applied to the upper disk 1. A compound made of vinyl chloride resin, filler, etc. is weighed and placed on the upper surface 14 of the lower disk 2. The upper disk 1 is lowered to pressurize the compound, and the lower disk 2 is rotated to twist the load cell 17. And the load applied to the axial pressure load cell 38 was measured and recorded. Next, adjust the stopper fixture 25 to make the gap between the upper and lower disks 1 and 2 1.
Figure 4 shows the change in the measured torsional torque value over time after similar measurements were made with the torque changed to mm, 1.5 mm, 2 mm, etc. A in Figure 4 indicates 0.5 mm.
The measurement values are set in mm, B is 1mm, C is 1.5mm, and D is 2mm. Figure 4 shows that the initial torque decrease was due to the temperature increase in the compound, and after a period of stability, the torque value further decreased due to the temperature increase caused by frictional heat generation. The smaller the gap between 1 and 2, the more noticeable it was. From the value of the axial pressure torque measured at the same time, it was possible to evaluate the change in the magnitude of the surface pressure applied to the material due to the gap between the upper and lower disks 1 and 2. By conducting such a test by changing the set temperatures of the upper and lower disks 1 and 2, the rotation speed of the lower disk 2, the amount of material, etc.
We were able to estimate the processing conditions for achieving good penetration between rolls and screw penetration.

Measurement of adhesion of molding material, which is characterized by placing the upper disc down, pressurizing the molding material, and rotating the lower disc while measuring the load on the upper disc using a falling load cell and an axial pressure load cell. Law.
