  • B 2 O 3 is also a component that forms the network structure of glass. Further, B 2 O 3 is also a component having an effect of reducing the dielectric constant of the glass composition. However, compositions containing an excess of B 2 O 3 tend to be inferior in acid resistance. Therefore, the content of B 2 O 3 may be 0.01% or more, 0.05%, and further 0.1% or more. The content of B 2 O 3 may be 2% or less, 1% or less, and further 0.5% or less, particularly 0.3% or less. B 2 O 3 is an optional component and may not be substantially contained.
  • (RO) RO is also a component that enhances chemical durability in this embodiment.
  • the total content of RO that is, the total content of MgO, CaO, SrO, and ZnO is 0.01% or more, 0.05% or more, 0.1% or more, 0.2% or more, Further, it may be 0.3% or more, particularly 0.4% or more. If the RO content is too high, a sufficiently low dielectric constant cannot be obtained.
  • the RO content is 4% or less, 2% or less, 1.7% or less, 1.5% or less, and further 1% or less, especially 0.8% or less, and in some cases 0.5% or less. May be good.

  • the ratio of the CaO content to the MgO content is 2 or more, 3 or more, and further 4 or more.
  • MgO and CaO are individually optional components like SrO and ZnO. MgO and CaO may not be substantially contained, respectively.
  • the form of the glass filler is not particularly limited, but may correspond to at least one selected from, for example, flake-shaped glass, chopped strand, milled fiber, glass powder, glass beads, flat fiber, and flaky glass. .. However, these forms are not strictly distinguished from each other. Further, two or more kinds of glass fillers having different forms may be used in combination as a filler.
  • the glass filler may have a fibrous shape or another shape, and when it has a fibrous shape, it is 30 mm or less, 10 mm or less, and further 5 mm or less, particularly less than 3 mm. It preferably has a fiber length. However, the glass filler may be longer.
  • each form will be described.
  • Each strand 26 is wound around a cylindrical tube 29 fitted in a collet 28 while being twilled by a traverse finger 27.
  • the cylindrical tube 29 around which the strands 26 are wound is removed from the collet 28 to obtain a cake (strand winding body) 30.
  • the form of contact between the glass filler precursor and the acidic solution is not particularly limited, and for example, the glass filler precursor can be immersed in the acidic solution held in the container.
  • the acidic solution in contact with the glass filler precursor is preferably heated.
  • the temperature of the preferred acidic solution is 40-90 ° C, especially 70-90 ° C.
  • the time for contacting the glass filler precursor with the acidic solution is not particularly limited and depends on the concentration and temperature of the acidic solution, for example, 1 to 48 hours.
  • the glass cloth and long glass fibers according to the present invention can be produced according to the above-mentioned method for producing a glass filler.
  • a glass cloth is first produced by elution of long glass fibers from a long glass fiber precursor through an elution step of eluting at least a part of the mother glass composition. After this elution step, as described above, a drying step and a heating step are appropriately carried out. Then, using the obtained long glass fibers, a glass cloth is produced according to a known method. However, the elution step may be carried out on a glass cloth precursor previously formed by using long glass fibers.
  • the resin-containing composition according to the present invention is not particularly limited, but may be, for example, a sheet molding compound, a bulk molding compound, or the like.
  • the resin-containing composition may contain the glass filler according to the present invention in a scattered state, or may contain the glass filler in a state of forming a molded product such as a glass mat.
  • the permittivity and the dielectric loss tangent at each frequency were measured using a permittivity measuring device by the cavity resonator perturbation method.
  • the measurement temperature was 25 ° C.
  • the dimensions of the measurement sample were a rectangular parallelepiped with a bottom surface of 1.5 cm on a side and a length of 10 cm.
  • This sample was prepared by putting a glass filler in a stamping die and compressing it with a hydraulic press to form the above rectangular parallelepiped shape.
  • This sample has vacancies and its measurements do not directly indicate the true value of the glass filler. However, the true value of the glass filler was calculated by converting the vacancies as air.
