Description

White carbon black special for aircraft tire marking adhesive and preparation method thereof
Technical Field
The invention relates to a special white carbon black for aircraft tire marking adhesive and a preparation method thereof.
Background
The aviation tire bears high-load friction in the taking-off and landing processes, so that the judgment of the abrasion degree of the tire is very important, and the judgment is related to the use safety and maintenance of the aviation tire. The marking compound therefore has unique requirements for the properties of the white carbon black.
