In the production of brake shoes, the utilization of Rubber Accelerator (MBTS/DM) in brake shoes mixtures and mixes, especially in brake shoes friction materials, has brought about a series of changes. This substance plays a crucial role in enhancing the performance of brake shoes, yet it also comes with its own set of advantages and disadvantages.

One of the primary functions of Rubber Accelerator (MBTS/DM) is to speed up the curing process of the rubber components in brake shoes friction materials. It can reduce the curing time by approximately 30 – 40%. For example, without the accelerator, the curing process of a typical brake shoes mixture might take 60 minutes, while with the addition of an appropriate amount of MBTS/DM, it can be shortened to 36 – 42 minutes. This not only improves production efficiency but also allows for higher – volume production in a shorter time frame.

MBTS/DM can significantly enhance the mechanical properties of the brake shoes friction materials. Tests show that the tensile strength of the brake shoes mixture with the accelerator can increase by 20 – 30%. In a standard tensile – strength test, the sample without the accelerator had a tensile strength of 10 MPa, while the sample with the added accelerator reached 12 – 13 MPa. This improved tensile strength contributes to better durability and wear – resistance of the brake shoes.

Although the addition of Rubber Accelerator (MBTS/DM) incurs a certain cost, in the long – term production process, it can be cost – effective. Due to the shorter curing time and improved product quality, the overall production cost per unit can be reduced by about 15 – 20%. This cost reduction is achieved through higher production efficiency and fewer product failures during the manufacturing process.

One of the main drawbacks of using MBTS/DM is the risk of over – curing. If the dosage is not accurately controlled, over – curing can occur, which leads to a decrease in the flexibility and toughness of the brake shoes friction materials. In extreme cases of over – curing, the tensile – elongation ratio of the material can drop by 40 – 50%. This reduction in flexibility may cause the brake shoes to become brittle and more prone to cracking during use.

MBTS/DM contains certain chemical components that may pose environmental and health risks. In the manufacturing process, if not properly managed, it can release harmful substances. For example, it may emit small amounts of sulfur – containing compounds during the curing process. Prolonged exposure to these substances in the workplace can be harmful to the health of workers. Additionally, after the brake shoes reach the end of their service life, the disposal of the materials containing MBTS/DM may also cause environmental pollution if not handled properly.

In conclusion, Rubber Accelerator (MBTS/DM) offers significant advantages in the production of brake shoes, such as accelerating the curing process, enhancing mechanical properties, and being cost – effective in the long run. However, its potential for over – curing and environmental and health concerns cannot be ignored. Manufacturers need to carefully balance these factors to make the best use of this accelerator in brake shoes production.
