Problems solved by technology

[0018] On the other hand, for the problem that sufficient antibacterial properties cannot be obtained because the surface layer prevents the antibacterial agent from seeping out to the surface, it is proposed to contain 100 parts by weight of the resin component and 0.1 to 30 parts by weight of a metal-based antibacterial agent loaded with metal on the fibrous object. And the antibacterial resin composition of 0.1~30 parts by weight of hydrophilic component

Embodiment 30

[0160] Embodiment 30 has cooperated Ny, spherical glass and silver antibacterial agent. As the silver antibacterial agent, AJ10N (Ag0.3% by weight) (manufactured by Sinanen Zeomic Co., Ltd.) which is silver zeolite was used. And the weight compounding ratio of Ny of embodiment 30, spherical glass and silver antimicrobial agent is made 40: 59.95: 0.05, 40: 59.90: 0.1 and 50: 49.95: 0.05, 50: 49.90: 0.1 totally 4 kinds of levels of implementation example. In addition, examples of silver antibacterial agents include silver zeolite, silver glass, and silver zirconium phosphate.

Embodiment 35

[0179] Embodiment 35 has cooperated spherical glass, PP, antibacterial agent and antifungal agent. Silver glass (PG721ST; product of Koichi Glass Co., Ltd.) was used as the silver antibacterial agent, and copper oxide was used as the antifungal agent. In Example 35, two levels of spherical glass, PP, silver glass, and copper oxide were prepared at a weight ratio of 40:59.85:0.1:0.05 and 50:49.85:0.1:0.05.

Embodiment 40

[0201] Embodiment 40 has matched spherical glass, PP and flame retardant. Antimony trioxide was used as a flame retardant. In addition, four levels of spherical glass, PP and antimony trioxide weight compounding ratios of 40:56:4, 40:54:6 and 50:46:4, 50:44:6 were implemented in total. example.

Abstract

A molded resin containing a filler and glass is provided which has no skin layer in the surface and suffers no deformation such as sink or warpage. Even when the amount of the filler incorporated is small, the filler can sufficiently perform the same function as the function of the filler incorporated in amounts conventionally used. The resin is one member selected from a group consisting of polyethylene resins, polypropylene resins, polyethylene terephthalate resins, and polyamide resins. The glass is solid spherical glass beads having an average particle diameter of 10-40 [mu]m. The proportion of the solid spherical glass beads is in the range of 40-70 wt.%. An examination by laser Raman spectroscopy shows that the glass-containing molded resin has no skin layer in the surface thereof. The solid spherical glass and the filler are present in the surface of the molded resin. The filler is hence capable of performing the function thereof.

Description

technical field [0001] The present invention relates to a resin molded article containing filler and glass. The surface of molten thermoplastic resin mixed with spherical glass and filler can prevent sink marks without forming a surface layer by contacting the wall surface of a mold such as an injection molding device. , warping and other strains, and can give full play to the role of fillers. Background technique [0002] When resin pellets are used to form a resin molded product by molding with a molding machine, it is known that when molten resin is injected into a cavity, the molten resin is rapidly cooled on the wall surface of the mold forming the cavity, and the resin can be formed on the wall surface and solidified layer (hereinafter referred to as the "surface layer"). Specifically, the surface of the molten resin that comes into contact with various mold surfaces for injection molding, blow molding, or profile extrusion inevitably forms a skin. Since the surface ...
