Description

  INDUSTRIAL APPLICABILITY The present invention has low linear expansion, and has flame retardancy and conductivity, and can be suitably applied to OA equipment, general electric machine parts, automobile parts, heavy electric parts and the like. The present invention relates to a resin composition, an integrally molded article of the thermosetting resin and a glass member, and a method for producing the same.

  A typical thermosetting resin used for integral molding with a glass member is BMC (Bulk Molding Compound) mainly composed of an unsaturated polyester resin, a low shrinkage agent, a filler and glass fiber. BMCs made of such components are widely used in OA equipment, general electromechanical parts, automobile parts, heavy electric parts, and the like because cured products having excellent dimensional accuracy, mechanical strength, heat resistance, and the like can be obtained.

The integral molding of the thermosetting resin and the glass member is generally performed by transfer molding or injection molding. The cured product of the unsaturated polyester resin composition used for the integrally molded product obtained by such a method usually has a linear expansion coefficient of 12 × 10 ^{−6 to} 25 × 10 ⁻⁶ / ° C. On the other hand, the coefficient of linear expansion of glass is about 8 × 10 ⁻⁶ to 10 × 10 ⁻⁶ / ° C., and the coefficient of linear expansion of a normal unsaturated polyester resin composition is larger. For this reason, warpage is likely to occur during integral molding due to such a difference in linear expansion coefficient.

Therefore, from the viewpoint of suppressing the warpage of the integrally molded article, it is desirable that the thermosetting resin integrally molded with the glass member has a degree of linear expansion close to that of glass, that is, a low coefficient of linear expansion.
On the other hand, for example, Patent Document 1 describes a thermosetting resin containing 1% by weight or more of a carbon fiber having a linear expansion coefficient of 0 or less.

However, a thermosetting resin containing carbon fibers as described in Patent Document 1 may have conductivity, but is generally inferior in flame retardancy.
As a means for imparting flame retardancy, there is a method of adding a filler such as aluminum hydroxide, but in order to obtain sufficient flame retardancy by such a method of adding a filler, a large amount of filler is required. Must be blended. In this case, since the compounding ratio of the filler is increased, the conductivity is reduced, and the fluidity of the raw resin composition before curing is reduced.

  The present invention has been made under such a circumstance, has a low linear expansion, suppresses the occurrence of warpage when integrally formed with a glass member, and has a flame retardant and conductive heat. It is an object of the present invention to provide a resin composition for obtaining a curable resin, an integrally molded product of the thermosetting resin and a glass member, and a method for producing the same.

Using the thermosetting resin composition produced above, integral molding with a glass member was performed by transfer molding as follows.
A glass member having a length of 230 mm × a width of 20 mm × a thickness of 1.5 mm was placed in a lower mold of a mold heated to 150 ° C. and covered with an upper mold. Then, 100 g of the thermosetting resin composition was put into the pot of the upper mold, pushed with a plunger, poured into the mold through a gate port through a runner, and the thermosetting resin composition was thermoset. After cooling, an integrally molded product having a length of 240 mm, a width of 40 mm, and a thickness of 1.5 m, in which the center is the glass member 1 and the side is the thermosetting resin 2 as shown in FIGS.

[ Reference Example 1, Examples 3 to 14, Comparative Examples 1 to 7]

Further, using the obtained resin composition, an integrally molded article with a glass member was produced in the same manner as in Example 1.

[Evaluation of various physical properties]
Each of the thermosetting resin compositions and each of the integrally molded articles obtained in the examples and comparative examples were evaluated for various physical properties by the following test methods. These evaluation results are summarized in Table 1 below.

(1) Flowability The flow length (spiral flow value) of the thermosetting resin composition in a spiral flow test was used as an index of flowability. In the spiral flow test, a spiral flow mold having a trapezoidal cross section (upper bottom a = 6 mm, lower bottom b = 8 mm, height h = 2 mm (both inner diameters)) as shown in FIG. The spiral flow value was measured under the conditions of a raw material charge amount of 50 g, a molding temperature of 140 ° C., and a molding pressure of 5 MPa. The larger the spiral flow value, the higher the fluidity.

(2) Flame retardancy Using 340 g of the thermosetting resin composition, a flat plate of 320 mm × 220 mm × 3 mm was molded by a compression mold heated to 160 ° C. After curing, the molded product was taken out of the mold, and a test piece of (125 ± 5) mm × (13 ± 0.5) mm × 3 mm was cut out.
Evaluation was carried out in a vertical combustion test in accordance with UL94 V-0 standard. In Table 1 below, those satisfying the V-0 standard are represented by ○, and those not satisfying the same are represented by x.

(3) Conductivity Using 300 g of a thermosetting resin composition in a mold under the conditions of a molding temperature of 160 ± 2 ° C., a molding pressure of 15 MPa, and a curing time of 360 seconds, a dish shape as shown in FIG. (200 mm, d = 180 mm, e = 30 mm, t = 3 mm). After curing, the molded product was taken out of the mold, and the insulation resistance was measured with a battery-type insulation resistance meter (manufactured by Kyoritsu Electric Instruments Co., Ltd.). The smaller the insulation resistance value, the higher the conductivity.

(4) Warp The integrally molded article is placed in a flat shape with the front surface or the back surface in FIG. 1 as an upper surface, and the degree of warpage is evaluated by the amount of warp x in the length direction with respect to the placement surface as shown in FIG. did. In addition, the case where it is convex on the surface side is represented as “+”, and the case where it is concave on the surface side is represented as “−”. The smaller the absolute value of the amount of warpage, the more the occurrence of warpage is suppressed.

As can be seen from the results shown in Table 1, when the blending amount of the carbon fiber in the thermosetting resin composition was small (Comparative Example 1), the conductivity was low and the warpage during integral molding was large. Also, when the blending amount of the carbon fiber was large (Comparative Examples 2 and 3), the warpage at the time of integral molding was large, and the fluidity was low. When the red phosphorus-based flame retardant was not contained in a predetermined amount (Comparative Examples 4 and 5) and when the blended amount of aluminum hydroxide was small (Comparative Example 6), a cured resin having sufficient flame retardancy was obtained. Could not be obtained. When no carbon powder was contained (Comparative Example 7), the conductivity was low.
In comparison with these, Examples 1 to 14 were found to have reduced warpage during integral molding and were also excellent in flame retardancy and conductivity. In particular, Examples 1 to 12 were excellent in the fluidity of the resin composition and also excellent in moldability.
