ABSTRACT:
A preparation process of a phenol-based resin composition by conducting a crosslinking reaction of a specific silicone compound in the phenol-based resin in the presence of a specific emulsifier, crosslinking agent and catalyst and by the addition of water to disperse resulting silicone rubber as fine particles in the phenol-based resin.
The phenol-based resin of the invention has no time-dependent variation in molding processability and molded products are stable and has no time-dependent change in impact resistance, flexural strength and thermal shock resistance (heat crack resistance), and hence the phenol-based resin composition is used for various molding materials and friction materials which require excellent mechanical strength, crack resistance, thermal shock resistance, stress relaxation resistance or abrasion resistance.
