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
The present invention relates to a kind of organic polymer composite, more particularly, relate to the special-purpose high strength Reinforced Nylon of a kind of bicycle brake disc material.The invention still further relates to the method for making this nylon raw material.
Background technology
Development along with people's social life level, for reasons such as transportation equipment, body-building apparatus, environmental protection oil-saving discharging-reducings, the language function of bicycle constantly increases, and usage quantity is also increasing, to its higher security, more lightweight, more fashion requirement attractive in appearance is also more and more higher.Therefore, high performance engineering plastics alternative metals is used for bicycle also becomes trend.
The brake disc of bicycle is the important component part of bicycle, and operating security is quite crucial to car load.At present, the bicycle brake disc is produced by the die casting mode with high-strength aluminum alloy material mostly.Also have minority producer using plastic material production, but its intensity and security are very unreliable, have relevant not good news to spread out of in the industry repeatedly.The present technique invention produces in order effectively to overcome this phenomenon, need give material reliable mechanical strength, work-ing life, attractive in appearance, good processibility, suitable cost control, and the good tack of spraying paint also will be arranged.
Summary of the invention
The objective of the invention is to, the special-purpose high strength Reinforced Nylon of the bicycle brake disc material of the good and compliance with environmental protection requirements of a kind of braking effect is provided.
In order to achieve the above object, technical scheme provided by the invention is as follows: form nylon 6:49.5-95%, alkali-free glass fiber: 5-50% by weight by following composition; Thermo-stabilizer: 0.13.0%, glass treatment agent: 0.1-3.0, oxidation inhibitor: 0.1-1.0%; Other auxiliary agents: 3.3-9.5%.
The special-purpose high strength Reinforced Nylon of bicycle brake disc of the present invention preparation methods, comprise the steps: earlier with nylon 6, thermo-stabilizer, glass treatment agent, oxidation inhibitor, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, naturally place after 12 hours and in time under the screw combinations situation that medium tenacity is sheared, add alkali-free glass fiber in proportion again by the side through twin screw extruder, under vacuum state, with mixing the extruding of 270 degree, the pelletizing of water-cooled tie rod makes the special-purpose high strength Reinforced Nylon of bicycle brake disc material through screening and dewatering.
The special-purpose high strength Reinforced Nylon of bicycle brake disc of the present invention material, result of use is similar with the high-strength aluminum alloy material that uses at present, and production procurement is convenient, also meets all environmental requirements, comprehensive like this product competitiveness that improved simultaneously.
Embodiment
Below be the embodiment of the special-purpose high strength Reinforced Nylon of bicycle brake disc of the present invention material, therefore do not limit protection scope of the present invention.
Embodiment one, and the special-purpose high strength Reinforced Nylon of a kind of bicycle brake disc material is provided, and forms nylon 6:58.5%, alkali-free glass fiber: 33% by weight by following composition; Thermo-stabilizer: 0.5%, the glass treatment agent: 1.0%, oxidation inhibitor: 0.5%; Other auxiliary agents: 6.5%.
Earlier with nylon 6, thermo-stabilizer, glass treatment agent, oxidation inhibitor, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, stainless steel, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather, place naturally then and re-use after making its sufficient reacting in 12 hours; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; The Halogen alkali-free glass fiber is added in proportion by the side; Keep vacuum state and 270 the degree condition is mixing extrudes; Adopt water-cooled tie rod pelletizing mode, promptly make the special-purpose high strength Reinforced Nylon of bicycle brake disc material through screening and dewatering.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
