Definitions
- the present invention relates to a calender roll made of resin, such as a calender roll for papermaking, a calender roll for fiber, and a calender roll for magnetic tape.
- calender rolls for papermaking include so-called cotton rolls made of raw wire, cotton, absorbent cotton, paper, wool, etc., ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ , ⁇ ⁇ ⁇ ⁇ ⁇ It is being used vigorously.
- Rolls using these fibers are not uniform in hardness because they are aggregates of fibers. Therefore, in actual use, preliminary operation is performed to make the surface hardness of the rolls uniform to some extent. A great deal of time is spent on the work to equalize the hardness of the surface.
- these rolls made of textiles generate a large amount of internal heat when used, and when operated under high pressure and high speed, the interior burns and becomes unusable. Also, if an accident such as running out of paper occurs during operation, wrinkles will occur on the paper to be processed, and these papers will be calendared in an overlapping state. At this time, since the roll has poor resilience, paper marks are left on the roll surface, and the paper passing therethrough is damaged.
- narrow paper When processing wide paper after processing, there is a problem that dents in the edge of narrow paper directly affect wide paper. Therefore, a number of spare rolls are prepared, and the rolls are replaced each time the paper width changes, and if the scratches occur due to the overlapping of the paper, they are polished again.
- thermoplastic monocasting mouth is also used.
- This generates a large amount of reaction heat during the polymerization reaction, and becomes high temperature.
- the mold shrinkage is also large. Therefore, this roll is forced to adopt a method in which a hollow pipe made of resin is fitted directly on the surface of the core metal or through a lower winding layer of urethane rubber or the like.
- this roll since the core metal or the lower winding layer and the resin layer are not adhered to each other, they cannot withstand high-speed rotation under high pressure and may scatter when the resin layer breaks down, damaging equipment and causing personal injury. There is.
- the temperature at the characteristic inflection point of the storage elastic modulus (E ') of the resin forming the surface layer bonded to the surface of the cored bar is calculated by adding 10'C to the temperature of the resin during use. And a temperature lower than the temperature obtained by adding 80 to the temperature at the time of using the resin, and the resin has a Shore D hardness in the range of 75 to 97. This is a resin roll for rendering.
- the resin constituting the surface layer is a large low-
- the raw material should be of a liquid type at the time of molding. It can be poured into a mold and molded into a roll, while the temperature at the characteristic inflection point of the storage elastic modulus (E ') and the Any material that satisfies the requirements for D-hardness is acceptable. More preferably, it is preferable that the calorific value during the cross-linking reaction is small, so that the surface of the cored bar can be easily molded integrally with an adhesive.
- a resin include a polyurethane resin, a polyisocyanurate resin-crosslinked polyesteramide resin, and a dibox resin.
- the temperature range of the characteristic inflection point of the storage elastic modulus (E ') of the above resin is set to be higher than the temperature of the resin at the time of use plus 10 ° C, and lower than the temperature of the resin plus 80'c.
- the reason is as follows. In the former case, theoretically, it may be higher than the resin temperature at the time of use. However, in reality, the temperature of the resin depends on the characteristics of the storage elastic modulus (E ') of the resin due to variations in the equipment that uses the force render rolls and variations in working conditions. Since the temperature exceeds the inflection point and the resin softens rapidly, a width of 10 is provided to prevent this phenomenon. 80 in the latter case.
- the temperature at the characteristic inflection point of the storage elastic modulus (E ') is the storage elasticity measured by changing the temperature under a constant frequency in the measurement with a viscoelastic spectrometer.
- the constant frequency is usually in the range of 10 to 50 Hz.
- the heating rate is usually set at 2 3 ⁇ 4 V min.
- the calendering roll of the present invention has a characteristic inflection point of the storage elastic modulus (E ') even when the operating conditions are too severe and the surface of the roll is abnormally heated and partially expanded at that portion. Temperature is within the specified range, the heat-generating part softens in the initial stage of expansion, so that concentrated load does not occur anymore, and even if that part ruptures, an arc crack occurs on the surface of the resin layer It does not lead to the scattering of the resin layer. For this reason, there are many workers when using the calendar roll, and even if the resin layer ruptures due to partial heat generation, it does not scatter and can prevent personal injury.
- E ' characteristic inflection point of the storage elastic modulus
- the reason for setting the Shore D hardness of the resin to 75 to 97 is as follows.
- the value of 75 or more is intended to solve the following problems. is there. That is, the calendar roll is usually used at high pressure and high speed rotation, and if the hardness does not drop to 75, the amount of deformation of the resin due to the operating pressure increases. As a result, the inside of the resin generates heat and is destroyed. In general, when a high pressure is applied to a hard resin, the elongation of the resin itself cannot follow the amount of deformation before it generates heat, so that hard resin is broken down.
- the reason for setting it to 97 or less is to solve the following problems. That is, when it is usually used as a resin roll, it is polished with a crown so as to make uniform contact with the mating metal roll or the workpiece, but if the precision is poor, it may be partially applied. May receive full load. In this case, if the hardness is lower than Sho-D97, there is no problem because the deformation is large and other parts are affected, but if the hardness is high (when exceeding 97), the deformation is small. However, the entire load is partially received, resulting in an overload and destruction of the resin layer.
- the crown control roll is coated with resin, the surface temperature of the roll is detected by a sensor, and when partial heat is generated, the pressure in that part is reduced to change the crown.
- partial heat is generated.
- the resin at that location thermally expands and protrudes.
- a concentrated load is applied to these protruding portions, generating more heat, and the temperature is further increased by repeating this operation.
- the figure shows the relationship between the storage modulus (E) 'of the resin and the temperature of the resin.
- thermosetting resin has a characteristic inflection point Ta, and when the temperature rises above this inflection point, the elastic modulus drops sharply.Now, the resin roll is operated at a resin temperature of 80. In the case of material A, even if partial heat is generated, if the point exceeds 100, the resin in that part softens and stops receiving the load, and the other part does not generate heat. Catch the load on the surface. For this reason, if the temperature rises due to partial heat generation, it stops at a certain temperature and does not lead to ⁇ -l rupture.
- the characteristic inflection point Ta of this resin must be higher in the range of 10'C to 80 than the temperature of the resin in actual use.
- Examples of the material A are Example 1 described later, and examples of the material B are Examples 3 and 4. Example 2 is intermediate between the two. Examples of C and D materials are Comparative Examples 1, 2, and 3.
- FIG. 4 is a characteristic diagram illustrating a relationship.
- Sannicks HD402 of Kamigaki is a polyether polyol manufactured by Sanyo Chemical Co., Ltd. and has a hydroxyl value of 394.
