Then, the steel plate 7 (made of SKD61 steel and measuring 100 ⁇ 100 mm in length and width and 10 mm in thickness) was placed on a heater. The temperature of the steel plate 7 was measured using a thermocouple 8 inserted therein to a position located 2 mm below the surface of the middle portion of the steel plate 7 in a planar direction and adjusted to the set temperatures of 300° C., 350° C., and 400° C.

  • the thickness of the coating considerably widely varies depending on the types of the solid lubricant, the thermosetting resin, and the polymer compound and the blending amounts thereof. Therefore, by considering the type of a molten metal, forming conditions such as a temperature, the peelability of the coating after forming, and the like and adjusting the thickness of the coating to a predetermined value, forming can be performed.
  • each of the die release agent compositions was applied onto the steel plate 7 by spray coating to form a coating.
  • 25 g of a molten aluminum alloy (“ADC12” described in JIS K 2219) at 680° C. was supplied [see FIGS. 2( b ) and 3 ( b )]. Then, the measurement of the temperature of the steel plate 7 was continued and the maximum temperature of the steel plate was checked.
  • Example 1 TABLE 4 Die Release Maximum Temperature Agent Composition of Steel Plate(° C.)
  • Example 2 440
  • Example 3 435
  • Example 4 475
  • Example 5 440
  • Example 6 465
  • Example 7 460
  • Example 8 455
  • Example 9 435

  • the maximum temperature of the steel plate ranging from 430° C. in Examples 1 and 10 to 475° C. in Example 4 has the difference of 45° C. between the lowest and highest temperatures and the heat retaining performance considerably differs depending on the composition of the die release agent composition. Therefore, by considering the heat retainability in conjunction with the other performances such as the adherability, peelability, and the like, the composition of the die release agent composition can be set.
  • each of the die release agent compositions was applied onto the steel plate 7 by spray coating. Then, the steel plate 7 was held as it was for 30 seconds and then a molten aluminum alloy was supplied thereto in the same manner as for the heat retaining property in (2) described above.

  • Example 6 each of Example 6 in which the synthetic wax, graphite, and a phenol resin were used respectively as the polymer compound, the solid lubricant, and the thermosetting resin and Example 7 in which the synthetic wax and graphite were used and a urea resin was also used as the thermosetting resin had excellent peeling performance irrespective of the temperature of the steel plate and it can be seen that these die release agent compositions can be used without considering the temperature of the steel plate.
  • Example 1 Using the mineral oil used in Example 1 as the mineral oil, the wax used in Example 1 as the polymer compound, the boron nitride used in Example 5 as the solid lubricant, and four types of phenol resins having different average molecular weights as the thermosetting resins, and using two types of melamine resins having different average molecular weights, a diallyl phthalate resin, and a urea resin, die release agent compositions were prepared in the same manner as in Example 1. Also, in the evaluation of the adhering performance described above, the upper-limit temperature of the die temperature at which the film thickness was not less than 10 ⁇ m was evaluated as the upper-limit temperature which allows adhesion. In addition, in the evaluation of the peeling performance of each of the coatings, the lower-limit value of the die temperature at which the A rating or the B rating was obtained was evaluated as the lower-limit temperature which allows peeling. The results of the evaluations are shown in Table 6.
  • the usable die temperature range differs depending on the type of the thermosetting resin. Accordingly, it will understood that the different types of the thermosetting resins are preferably selectively used in accordance with the die temperatures at which the die release agents are used. For example, when a product has a large thickness and accordingly the die temperature is inevitably high, it is preferable to use the phenol resin in Example 13 or 14 having a large average molecular weight. On the other hand, when the die temperature is low in such a case where enhanced cooling is performed to reduce the cycle time of forming, it is preferable to use the urea resin in Example 18 or the like. Thus, it can be seen that the adhering performance and the peeling performance each in accordance with the die temperature can simultaneously be obtained.
  • Example 1 Using the mineral oil used in Example 1 as the mineral oil, the wax used in Example 1 as the polymer compound, the boron nitride used in Example 5 as the solid lubricant, and a phenol resin as the thermosetting resin, the die release agent compositions were prepared in the same manner as in Example 1.
  • the phenol resin the four types of resins having different average molecular weights and used in Examples 11 to 14 were used. Specifically, using the phenol resins having number average molecular weights of 6000 (Examples 19 and 23), 10,000 (Examples 20 and 24), 45,000 (Examples 21 and 25), and 300,000 (Examples 22 and 26), specimens each as shown in FIG. 4 were produced and two heated iron plates were bonded thereto.
  • each of two iron plates Fa and Fb used for the production of the specimen in FIG. 4 is SUS304.
  • the dimensions of each of the two iron plates Fa and Fb include a length of 35 mm, a width of 10 mm, and a thickness of 2 mm.
  • a phenol resin layer P formed at one end portion of the iron plate Fa measures about 10 mm in length, about 10 mm in width, and about 0.2 mm in thickness (see FIG. 4( a )).
  • the specimen was produced by placing one end portion of the iron plate Fb heated to 350° C. or 500° C. on top of the phenol resin layer P of the iron plate Fa at a room temperature (25 to 30° C.) and then naturally cooling the iron plates Fa and Fb to a room temperature.
  • the failure shear stress was measured by pinching the other end portions of the iron plates Fa and Fb with the chucks of the tensile tester and pulling the iron plates Fa and Fb in the directions shown by the arrows in FIG. 4( c ) at a tensile rate of 0.1 mm/second.
  • thermosetting resin having a relatively small average molecule weight is used to allow a desired adhesion strength to be obtained.
  • thermosetting resin described above in (4) and the average molecular weight of the phenol resin described above in (5), it is considered that, in general, as the average molecular weight of a thermosetting resin is larger, the viscosity of the thermosetting resin when melted is higher and the thermosetting resin is less likely to be spread over the die surface. It is also considered that, as the average molecular weight is larger, the thermosetting resin sets in a shorter time and therefore the thermosetting resin is less likely to be spread over the die surface. Thus, as the average molecular weight is larger, the bonding area is smaller and the thermosetting resin sets in a shorter time. As a result, a sufficient adhesion strength is not provided and the failure shear stress serving as the index of the adhesion strength tends to decrease.
  • thermosetting resins were sprinkled alone. Accordingly, the result of the measurement may differ from that obtained when the thermosetting resins were sprinkled as die release agent compositions each containing other components.
  • Table 7 and FIG. 6 it can be seen that, as the average molecular weights of the phenol resins are larger, the adhesion area ratios are lower, and accordingly the failure shear stresses are smaller. Therefore, it will be understood that the phenol resins have generally the same tendencies.
  • the adhesion area ratio means [(Area over Which Phenol Resin is Actually Adherent to Iron Plate)/Area Sprinkled with Phenol Resin Powder)] ⁇ 100. It can be assumed that, when the temperature is 350° C. and the average molecular weight is 45,000, setting slows down to reduce the viscosity, increase the adhesion area ratio, and increase the failure shear stress. On the other hand, it can be assumed that, when the average molecular weight is 300,000, setting slows down but, due to the originally high viscosity, the adhesion area ratio does not increase and the failure shear stress increases, but only to a slight degree.
  • thermosetting resin that, as the average molecular weight is larger, the viscosity of the thermosetting resin when formed is higher and the time to setting is shorter. Therefore, it can be assumed that another thermosetting resin other than a phenol resin also has the same tendency. That is, it can be considered that not only the phenol resin but also another thermosetting resin such as a melamine resin or a urea resin has the same tendency.
  • the present invention can be used in a technical field in metal die forming, and can be used particularly in a technical field such as low-pressure casting of an aluminum alloy or the like or a squeeze casting method therefore, or die forging.
