Details Introduction

Modified wollastonite refers to a functional filler material obtained by surface treatment of natural wollastonite through physical or chemical methods. Wollastonite (CaSiO3) is a chain-like silicate mineral known for its excellent thermal stability, chemical stability, high aspect ratio, low oil absorption, electrical insulation, and relatively high mechanical strength.

Modified wollastonite powder has a wide range of applications, particularly prominent in the brake pad industry.

1. Role in brake pads:

• Improved friction performance: Modified wollastonite powder, due to its unique needle-like crystalline form, can enhance the friction performance of brake pads, especially maintaining a stable friction coefficient at high temperatures, preventing brake failure due to excessive heat.

• Enhanced mechanical properties: Adding modified wollastonite powder can increase the compressive strength and wear resistance of brake pads, extending their service life.

• Thermal stability: Wollastonite has excellent heat resistance, capable of absorbing a large amount of heat during high-temperature braking processes, and is not easily decomposed, helping to lower the working temperature of brake pads and improve safety.

• Environmental performance: Since wollastonite is a non-asbestos material, it serves as an ideal substitute for asbestos, meeting the modern automotive industry's requirements for environmental protection and health.

2. Modification methods:

• Surface modification: By using coupling agents, surfactants, etc., the surface of wollastonite powder is coated to better bond with matrix materials such as rubber and resin, improving interfacial adhesion and enhancing the overall performance of composite materials.

• Physical modification: This includes methods such as crushing, classification, and calcination to adjust the particle size distribution and crystalline structure of wollastonite powder to meet the specific needs of different application fields.

3. Other application fields:

• In powder coatings, modified wollastonite powder can improve the weather resistance, hardness, and adhesion of the coating.

• In the ceramics industry, it can be used in glazes and bodies to improve the mechanical properties and thermal stability of ceramic products.

• In the plastics and rubber industries, as a filler or reinforcing agent, it can reduce costs while increasing the dimensional stability, hardness, and impact strength of products.

• In construction engineering, modified wollastonite powder can be used as an additive in concrete and mortar to enhance the strength and durability of building materials.

In summary, modified wollastonite powder plays a crucial role in brake pad manufacturing due to its superior performance characteristics, enhancing the overall efficiency and safety of braking systems.
