Abstract

The invention discloses a nylon plastic bearing retainer for a draw-bar box and a preparation method of the nylon plastic bearing retainer. According to the formula of the nylon plastic bearing retainer, nylon 66 and nylon 6 are taken as a compound basic material, through adding materials of short-cut glass fibers, a surface treating agent, bisphenol A diglycidyl ether, an MBS flexibilizer, inorganic nonmetal nano particles, a heat stabilizer, an antioxidant, a lubricating agent and the like, the notch impact strength, the tensile strength and the bending strength of the nylon plastic of the bearing retainer provided by the invention are all higher than those of common nylon plastic, more importantly, the nylon plastic has very high low-temperature-resistant capability, and the lowest using temperature can reach more than subzero 20 DEG C, so the requirements of the nylon plastic bearing retainer for the draw-bar box in a cold region are greatly met.

Description

technical field [0001] The invention relates to a nylon plastic bearing cage for a trolley case and a preparation method thereof. Background technique [0002] As we all know, the bearing cage is the core component of the luggage, and the damage of this component will directly lead to the scrapping of the suitcase, so it is very important to improve the quality of the bearing cage. [0003] Usually, the bearing cage is made of high-strength brass, high-quality carbon steel, polytetrafluoroethylene, polyacetal, polyoxymethylene, nylon, polyphenylene sulfide, bakelite (phenolic molding compound) and other materials. Among them, the bearing cage made of nylon material has excellent formability and comprehensive performance, such as high strength, wear resistance, light weight and other characteristics, and is more and more favored by the industry. However, nylon also has disadvantages. Its amide polar group makes the water absorption rate high, low temperature resistance and i...
