Abstract: The invention relates to a method for improving braking performance of a microporous friction material under wet conditions. A hydrophobic agent is added into the components for preparing microporous friction material. The microporous friction material is prepared from the following raw materials in percentage by weight: 10%-20% of nano-silica modified phenolic resin, 4%-14% of butadiene-styrene rubber, 5%-15% of glass fiber, 2%-11% of aramid pulp, 4%-15% of aluminum borate whisker, 4%-10% of hydrophobic agent and 3%-8% of calcium silicate, 1%-8% of artificial graphite, 2%-8% of coke, 2%-7% of mica, 5%-10% of cryolite and 4%-10% of diatomite.
