で広く使用されている。Styrenic resins, i.e., polymers such as polystyrene obtained by polymerizing aromatic vinyl monomers such as styrene and α-methylstyrene alone, aromatic vinyl monomers listed above, and copolymers with these monomers. Copolymers such as AS resin obtained by copolymerizing with possible monomers such as acrylonitrile, methacrylonitrile, etc., aromatic vinyl monomers and monomers copolymerizable with these, rubber-like elastic bodies such as polybutadiene, etc. Copolymers such as ABS resins made by graft copolymerizing polymers have good moldability and impact resistance. It is widely used because it has chemical resistance.

末樹脂を使用する必要があった。In particular, since glass beads are spherical, even when blended with styrene resin, etc., there will be no anisotropy in the physical properties of the product and molding.
It has characteristics such as a smooth surface compared to fibrous fillers, but when kneading with styrene resin, etc., the resin is in the form of a pellet, making it difficult to use a general single-screw extruder, etc. Since uniform dispersion cannot be achieved using conventional equipment, it has been necessary to use large-scale equipment such as a Bumper'J-mixer or a pressure kneader, or to use powdered resin.
本発明者等は、上記の従来技術の問題点を解決し、より
耐摩耗性が優れかつ表面の滑らかなスチレン系樹脂組成

。The present inventors have conducted extensive research with the aim of solving the problems of the prior art described above and developing a styrenic resin composition with better wear resistance and a smoother surface, and a simpler manufacturing method. As a result of repeated efforts, the present invention was arrived at.

This is achieved by a wear-resistant styrenic resin composition containing 6 parts by weight.

る。A third object of the present invention is to provide a method for producing a styrene resin composition with excellent abrasion resistance and a smooth surface by a simple operation. In a method of manufacturing a wear-resistant styrenic resin composition by blending glass beads into a resin, 100 parts by weight of styrene resin pellets are mixed with 7 to 6 parts by weight of soric oil and 5 parts by weight of glass beads. ~35
This can be achieved by kneading parts by weight using a single screw extruder.

Soum, preferably 5 to 20 um, is suitable, and those whose surface has been treated with acrylic silane, glycido silane, amino silane, etc. are more preferred.
ガラスピーズの配合比率は、ポリスチレン、ＡＳ樹脂、
ＡＢＳ樹脂等のスチレン系樹脂１００重量部当り５〜３
５重量部、より好ましくは、１０〜３０重量部が適当で
ある。The blending ratio of glass beads is polystyrene, AS resin,
5 to 3 per 100 parts by weight of styrene resin such as ABS resin
A suitable amount is 5 parts by weight, more preferably 10 to 30 parts by weight.
スチレン系樹脂の形状はベレット、すなわち、粒径敢闘
程度の粒状のものでも、粉末であっても特に問題はない
が、ペレット状のものがより取り扱いが容易である。The shape of the styrenic resin may be pellets, that is, particles with a size comparable to those of average size, or powder, but there is no particular problem, but pellets are easier to handle.
ガラスピーズの配合比率は、５重量部未満では、耐摩耗
性があまり向上せず、また、３５重量部を越えるときは
、ガラスピーズのスチレン系樹脂中での分散が不良とな
り好ましくない。If the blending ratio of glass beads is less than 5 parts by weight, the abrasion resistance will not improve much, and if it exceeds 35 parts by weight, the dispersion of the glass beads in the styrene resin will be poor, which is not preferable.

樹脂１０θ重量部当り／ −Ａ重量部、好ましくは、ｌ
、５〜３重量部が適当である。The silicone oil may be a conventional polyalkylsiloxane or polyarylsiloxane, and the amount added is preferably 1/-A parts by weight per 10θ parts by weight of the styrene resin.
, 5 to 3 parts by weight is suitable.
１重量部未満では、シリコンオイルを添加した効果はあ
られれず、６重量部を越えるときはスチレン系樹脂成形
品の表面において剥離が起り、また成形収縮率が大きく
なるので好壕しくない。If the amount is less than 1 part by weight, the effect of adding silicone oil will not be obtained, and if it exceeds 6 parts by weight, peeling will occur on the surface of the styrene resin molded product and the molding shrinkage rate will increase, which is not desirable.
本発明に係るガラスピーズ及びシリコンオイルを配合し

効果は著るしいものがある。A composition in which glass beads and silicone oil according to the present invention are blended has a lower coefficient of friction and improved wear resistance than a composition in which glass beads are simply blended with a styrene resin. That is, the wear loss due to the worn wheels, which will be described later, is significantly reduced, and the synergistic effect accompanying the addition of silicone oil is significant.

極めて大である。 。The composition according to the present invention is prepared by adding predetermined amounts of styrene resin, glass beads, and silicone oil to a Banbury mixer.
Of course, it can also be produced by kneading with rolls, pressure kneaders, etc., or by kneading with a single-screw extruder using powdered resin, but it can also be produced using a single-screw extruder without using the easy-to-handle Pentz powdered resin. This makes it possible to cross-wire and disperse the glass beads uniformly. In this case, it is desirable that the glass peas be placed in the hopper of a single-screw extruder together with the pellets. According to this method, there is no need to use large-scale equipment and equipment (the industrial value is extremely large). .
