Abstract

The invention discloses cashew nut oil modified bisphenol A phenolic resin and a preparation method thereof, and belongs to the technical field of phenolic resin. The cashew nut oil is added into the phenolic resin, so that the cashew nut oil and silyl groups in the polysiloxane imide copolymer are mutually matched and have a synergistic effect, and the better mechanical strength of the phenolic resin is jointly ensured. Besides, nano titanium dioxide and carbon nanotubes are also added into the cashew nut oil modified bisphenol A phenolic resin, the nano titanium dioxide has ultrahigh chemical stability and anti-aging performance and can ensure high stability of the phenolic resin, and the carbon nanotubes have a special three-dimensional space structure, so that after the phenolic resin is added, a special hole structure can be introduced into the phenolic resin, the phenolic resin has high modulus and high strength, and the strength, elasticity and isotropy of the phenolic resin are improved.

Description

technical field [0001] The invention relates to the technical field of phenolic resins, in particular to a cashew nut oil modified bisphenol A phenolic resin and a preparation method thereof. Background technique [0002] Tire rubber is obtained by adding carbon black, various additives, nano-materials, etc. to synthetic rubber to improve the hardness, strength and elasticity of rubber. Carbon black is the most important reinforcing filler in tire rubber additives, which can significantly increase the mechanical strength and wear resistance of tire rubber. Because of this, the tires I see are usually black in color. However, as the amount of carbon black in tire rubber gradually increases, the processing performance of rubber becomes worse and worse, and the mechanical properties of tire rubber, including toughness, tear resistance and hardness, become poorer. Therefore, in the tire rubber production process, it is necessary to add a certain amount of phenolic resin adhesiv...
