Embodiment 1

[0009] Embodiment 1 provides a special high-strength reinforced nylon material for bicycle brake discs, which is composed of the following components by weight ratio, nylon 6: 58.5%, alkali-free glass fiber: 33%; heat stabilizer: 0.5%, glass fiber treatment agent : 1.0%, antioxidant: 0.5%; other additives: 6.5%.

[0010] First weigh nylon 6, heat stabilizer, glass fiber treatment agent, antioxidant, and other additives according to the proportion and mix them in the mixer at low speed for 10 minutes. The mixer adopts low speed mixing and is made of stainless steel. The gap between the cylinder wall is 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 the reaction to fully react before use; the twin-screw extruder is used for 36 hours. Diameter ratio, medium-strength shearing; h...

Abstract

The invention discloses a special high high-intensity reinforced nylon material for a brake disc of a bicycle, comprising the following components according to weight proportion: 49.5-95% of nylon, 5-50% of alkali-free glass fiber, 0.1-3.0% of thermal stabilizer, 0.1-3.0% of glass fiber treating agent, 0.1-1.0% of antioxygen, 3.3-9.5% of other accessories. The use effect of the special high high-intensity reinforced nylon material for the brake disc of the bicycle in the invention is approximate with that of the current high-intensity aluminum alloy material; the material is convenient for producing and purchasing; simultaneously, the material meets all environmental requirements, thereby comprehensively improving product competitiveness.

Description

technical field [0001] The invention relates to an organic polymer composite material, in particular to a special high-strength reinforced nylon material for bicycle brake discs. 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 disc of the bicycle is an important part of the bicycle, and it is quite critical to the safety of the whole vehicle in operation. At present, bicycle brake discs are mostly produced by die-casting with high-s...
