Embodiment 1

[0009] Embodiment 1 provides a special nylon material for bicycle brake handles, which is composed of the following components by weight: nylon 6: 49%, alkali-free glass fiber: 17%; heat stabilizer: 0.5%, glass fiber treatment agent: 1.0% , antioxidant: 0.5%; anti-impact agent: 8.5%; other additives: 23.5%;

[0010] First weigh nylon 6, heat stabilizer, glass fiber treatment agent, antioxidant, anti-impact agent, and other additives according to the proportion, and then mix them in the mixer at low speed for 10 minutes. The mixer adopts low-speed mixing, stainless steel material, and stirs The gap between the leaves and the cylinder wall should be less than 0.5 cm. The mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, without obvious agglomerates or agglomerations, and then placed naturally for 12 hours to allow them to fully react before use; twin-screw extruder Use 36 aspect ratio, medium-st...

Abstract

The invention discloses a special nylon material of a bicycle brake lever, consisting of the following components by weight percentage: 49.5 to 95% of nylon 6, 5 to 50% of alkali-free glass fiber, 0.1 to 3.0% of heat stabilizer, 0.1 to 3.0% of glass fiber finishing agent, 0.1 to 1.0% of antioxygen, 1 to 15% of shock resistant agent and 3.3 to 9.5% of other auxiliaries. The special nylon material of the bicycle brake lever has the similar using effect as the existing high-strength aluminum alloy material, the manufacturing and the purchasing are convenient and the special nylon material meets all the requirements of environmental protection, therefore, the product competitiveness is enhanced comprehensively.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a special nylon material for a bicycle brake handle. The invention also relates to methods of making such nylon stock. Background technique [0002] With the development of people's social living standards, due to reasons such as transportation equipment, fitness equipment, environmental protection, fuel saving and emission reduction, the use functions of bicycles continue to increase, and the amount of use is also increasing. Lightweight, more fashionable and beautiful requirements are also getting higher and higher. Therefore, it has become a trend to replace metals with high-performance engineering plastics for bicycles. [0003] The brake handle of the bicycle is an important part of the bicycle, and it is quite critical to the safety of the whole bicycle in operation. At present, bicycle brake handles are mostly produced by die-casting with high-str...
