Preparation and properties of rice husk ash silica filled natural rubber
Mixing natural rubber latex and rice husk ash silica through wet?mixing method is a sustainable approach to prepare the green tire tread with excellent mechanical properties, low rolling resistance, high abrasion resistance, and wet grip.Rice husk ash silica obtained from the chemical purification of rice husk ash is a bio?based silica. As a sustainable raw material, the bio?based silica has attracted much attention in recent years. It can be used to replace traditional carbon black and silica in tire rubbers. Our experimental results show that the bio?based silica can bring similar mechanical properties and higher wet grip to natural rubber in comparison with traditional silica. The wet mixing method is successfully used to disperse the bio?based silica in natural rubber latex, obtaining a bio?based silica/natural rubber composite with higher abrasion resistance and lower rolling resistance than the composite prepared by traditional dry mixing. The mechanical properties of bio?based silica/natural rubber composites depend on the silica loading and mixing methods. Mixing natural rubber and bio?based silica through wet?mixing method is a green and sustainable approach to the tread rubbers with excellent mechanical properties, low rolling resistance, high abrasion resistance, and wet grip.
