。[Detailed Description of the Invention] [Industrial Application Field] The present invention is particularly useful as a structural member, and is particularly useful as a wiring component,
This relates to thermoplastic resin compositions that can be used for electrical parts, electronic parts, etc., and its purpose is to improve surface hardness, wear resistance,
The objective is to provide various functions such as bending strength, bending elasticity, dimensional stability, heat resistance, electrical insulation, and thermal conductivity all at once.

品化するには、多大な設備と経験等が必要である。Conventionally, thermoplastic resins include general-purpose plastics and engineering plastics called engineering plastics or super engineering plastics, and although the latter have been improved in functionality, they naturally have their limits. On the other hand, in the field of ceramics, oxide-based general-purpose ceramics and non-oxide-based ceramics such as depressions and carbides are attracting attention as engineering ceramics, but commercializing them requires a great deal of equipment and experience. is necessary.

を完成した。As a result of various studies aimed at improving the high functionality of plastics that is closer to that of ceramics, especially the abrasion resistance and high hardness that were extremely difficult to achieve with conventional engineering plastics, the inventors of the present invention found that they could replace conventional fillers. The present invention was completed based on the discovery that it is sufficient to use silicon nitride and a surface treatment agent for silicon nitride in addition to conventional fillers.
本発明は、窒化珪素と窒化珪素のシラン系表面処理剤と
を含有してなる熱可塑性樹脂組成物である。The present invention is a thermoplastic resin composition containing silicon nitride and a silane-based surface treatment agent for silicon nitride.
以下、さらに詳しく本発明忙ついて説明する。Hereinafter, the present invention will be explained in more detail.

い。There are two types of silicon nitride: α-type and β-type. In the present invention, the same degree of effectiveness can be obtained using either form, so the inexpensive β-type or low-α type silicon nitride is used. It is desirable to use Further, from the viewpoints of crosstalk, filling properties, and moldability, the particle size is desirably 100 μm or less, particularly 50 μm or less.

エンジニアリングプラスチックでは困難であったもので
ある。The filling amount of silicon nitride is about 10 to 85 inches on the inside weight of the thermoplastic resin, but in order to improve dimensional stability, abrasion resistance, heat resistance, and thermal conductivity, it is necessary to fill the thermoplastic resin with 20 to 75 inches on the surface. 10 to 7 for improving hardness, bending strength, and bending elastic modulus
It is desirable to set it to 5%. If the amount is less than 10%, the effect of improving various functions will be small, and if the amount is more than 85%, crosstalk, filling properties, and moldability will deteriorate. In addition to the above-mentioned functions, it has been difficult to improve wear resistance and high hardness with conventional engineering plastics.
