Natural rubber has the characteristics of good elasticity, high strength, tear resistance, and wear resistance, and is an ideal raw material for the production of bicycle pedal glue. However, the price of natural rubber is high, and the full use of natural rubber cannot take the lead in the fierce market competition, so it is imperative to use low-priced rubber raw materials to replace natural rubber to produce bicycle foot covers. What low-cost rubber raw materials can be used in the production of bicycle pedal rubber? How to design a low-cost bicycle foot cover formula?
1. Secondary brand natural rubber
Sub-brand natural rubber is a secondary product with slightly substandard colors and indicators produced by factors such as raw material fluctuations, production process deviations, equipment failures and other factors in the processing process of natural rubber, with the basic performance characteristics of natural rubber, high mechanical strength, good elasticity, wear resistance, low temperature resistance, and the price is much lower than genuine natural rubber, which can completely replace the formula of genuine natural rubber to produce bicycle foot covers, effectively reducing the cost of raw rubber.
2. Latex recycled glue
Latex recycled rubber is processed from natural rubber waste rubber cups, rubber wires, waste latex gloves, latex finger covers, etc. as raw materials, with the basic performance characteristics of natural rubber, effective rubber hydrocarbon content, good elasticity, high mechanical strength, can replace natural rubber in whole or part to produce bicycle pedal rubber, reduce raw material costs. The price of black natural latex recycled rubber with the same index is lower than that of white latex recycled rubber, and the use of black natural recycled rubber can reduce the cost of raw materials more when producing black bicycle pedal rubber.
3. Tire recycling glue
Tire recycled rubber is a recycled rubber made of waste tires through crushing, desulfurization, refining and other processes, with the basic performance characteristics of rubber, the main components are natural rubber, general synthetic rubber and carbon black, and the compatibility with natural rubber is good, and can be mixed into the formula of natural rubber bicycle pedal rubber in a high proportion, reducing the amount of natural rubber and reducing the cost of raw materials under the premise of ensuring the performance of the foot cover.
4. Recycled rubber powder
Ordinary vulcanized rubber powder is a powdery substance of different particle sizes made of waste rubber products (mainly waste tires) by mechanical processing crushing or grinding, inheriting the elastic characteristics of rubber itself, containing a small amount of unsaturated double bonds, with re-crosslinking function, with a certain wear resistance, small density, low modulus, can be used with natural rubber, synthetic rubber, recycled rubber to produce bicycle foot rubber rubber, reduce raw material costs, improve rubber processing performance to a certain extent, improve the fatigue resistance of products, etc.
5. Natural rubber/tire recycled rubber/vulcanized rubber powder is used to produce bicycle foot cover formula
3# tobacco flake glue 30 parts, tire recycling rubber 70 parts, vulcanized rubber powder 40 parts, zinc oxide 3.3 parts, stearic acid 1.9 parts, anti-aging agent 0.7 parts, paraffin wax 0.7 parts, high wear resistance carbon black 20 parts, calcium carbonate 20 parts, aromatic oil 10 parts, accelerator M 0.65 parts, accelerator DM 0.8 parts, sulfur 1.95 parts; A total of 200 copies.
To reduce the production cost of bicycle pedal rubber, rubber product manufacturers can also use secondary brand natural glue, recycled rubber and recycled rubber powder, and some products can completely use tire recycled glue; To design a large number of bicycle pedal rubber E5LYY328 mixed with low-cost rubber raw materials, it is necessary to comprehensively consider the multi-faceted performance requirements of the foot sleeve and the budget of the finished product, including anti-slip, wear resistance, cold resistance, strength, permanent deformation, wear resistance and flexion times, etc., so as to reduce more raw material costs under the premise of ensuring the safety, durability and comfort of the finished product.
