Embodiment 1
[0086] (1) Production of prepreg
[0087] use figure 1In the shown device, the heat-resistant mat 1 (average thickness 6mm, average width 1050mm, average length 30mm, density 120kg / m 3 ) was pulled out, and immersed in an immersion tank T filled with a resole-type phenolic resin (thermal curing temperature: 150° C.) as the thermosetting resin 2 . The heat-resistant mat 1 is obtained by intertwining glass fibers with needle punching. Thereafter, it is dried at 60 to 130° C. with a dryer D, and then cut with a cutter C to produce a plurality of sheets containing 40% by mass of fibers derived from glass fiber mats and 60% by mass of a resol-type phenolic resin. Sheet (plate) prepreg3.
[0088] (2) Production of heat insulation materials
[0089] Five laminates L in which 13 sheets of the prepreg 3 obtained in (1) were laminated were produced, such as figure 2 As shown, the obtained five laminates L were stacked between the press plates of the press machine P with spacers in...
experiment example 1
[0092] The heat insulating material of the present invention is excellent in wear resistance and heat resistance due to the low content of the thermoplastic resin, which is shown in this experimental example.
[0093] (1) Manufacture of insulation material B
[0094] In Example 1, glass fiber paper ( Average thickness 0.78mm, basis weight 110g / m 2 ) instead of the heat-resistant mat 1, the same procedure as in Example 1 was carried out to produce a plurality of prepregs with an average thickness of 0.84 mm, a length of 2110 mm, and a width of 1050 mm. Then, except that a laminate L in which 57 sheets of the obtained prepregs were laminated was produced, it was carried out in the same manner as in Example 1 to obtain a heat insulating material B having a length of 2070 mm, a width of 1020 mm, and a thickness of 12 mm.
[0095] The obtained heat insulating material B contained 42 mass % of fibers, 50 mass % of resole type phenolic resins, and 8 mass % of thermoplastic resins. ...
