Can butyl reclaimed rubber be used in rubber roller production?

The butyl reclaimed rubber recovered from the waste butyl inner tube has excellent air tightness, heat resistance and chemical stability. It can replace some butyl rubber in the production of various IR products, under the premise of ensuring quality. Reduce the production cost; the rubber roller is a roll-shaped product made of metal material or other materials as the core and vulcanized by the outer rubber. It is one of the common rubber products. Can you use butyl reclaimed rubber to reduce the production cost of the rubber roller?

1. Butyl reclaimed rubber can produce rubber roller

The butyl reclaimed rubber synthesized from isobutylene and a small amount of isoprene has good air tightness and water tightness, and can maintain good stability at higher temperatures and chemical solvents. The produced butyl rubber roller has good acid resistance. Alkaline and good heat resistance, often used in color printing machinery, tanning machinery and coating equipment; butyl reclaimed rubber is processed from waste butyl inner tube, retaining the basic performance characteristics of butyl rubber. It has good compatibility with butyl rubber, and can theoretically replace some butyl rubber to produce rubber roller products and reduce production costs.

2. Advantages of butyl reclaimed rubber production rubber roller

The price of butyl reclaimed rubber is much lower than that of butyl rubber. The replacement of butyl rubber in the production of butyl rubber roller can reduce the production cost; the butyl reclaimed rubber has good fluidity and good plasticity, and the vulcanization flatness is good during vulcanization; The base rubber itself has a slow vulcanization rate and poor compatibility with other rubbers. The use of an appropriate amount of butyl reclaimed rubber can improve the vulcanization performance of the butyl rubber roll; the use of butyl reclaimed rubber and butyl rubber to produce the rubber roller Small consumption and better uniformity.

3. Precautions for the production of rubber rollers from butyl reclaimed rubber

The replacement of some butyl rubber production rubber rolls with butyl reclaimed rubber can reduce the cost of raw materials, improve the processing performance of rubber compound processing and reduce the energy consumption of production. However, in actual production, the mechanical strength of butyl reclaimed rubber and butyl rubber are certain. The difference, therefore, the amount of butyl reclaimed rubber in the butyl rubber roller should not be too much, and the amount of butyl reclaimed rubber should be increased as much as possible under the premise of qualified indicators. Since the molecular structure and performance characteristics of the butyl reclaimed rubber and the butyl rubber are different, the type and amount of the compounding agent in the butyl rubber roller formulation doped with the butyl reclaimed rubber should be appropriately adjusted.

The reasonable use of butyl reclaimed rubber in butyl rubber rolls can reduce the production cost under the premise of ensuring the quality of rubber rolls; the quality of butyl reclaimed rubber is as important as the design of butyl rubber rolls, and later will be discussed with you. The difference between the rubber roller formulation of butyl reclaimed rubber and the pure butyl rubber roller formulation.
