Abstract

The invention relates to the field of high polymer materials, in particular to a nano ceramic powder modified bismaleimide resin composite material preparation method. The method is characterized by including steps: stirring, by mass, 10-100 parts of bismaleimide resin and 10-100 parts of an allyl compound at 50-150 DEG C, and cooling to 90 DEG C after dissolution; adding, by mass, 10-100 parts of cyanate ester resin, 0.1-10 parts of nano ceramic powder and 0.1-10 parts of a thixotropic agent, and well stirring to obtain a nano ceramic powder modified bismaleimide resin composite material. According to the method, the bismaleimide resin and the allyl compound are prepolymerized prior to blending modification with the cyanate ester resin, the nano ceramic powder and the thixotropic agent. The method is simple in production process, and the obtained resin material has excellent mechanical properties, temperature resistance and abrasion resistance and is especially superior in hardness.

Description

technical field [0001] The invention relates to the field of thermosetting resin compositions, in particular to a method for preparing composite materials by modifying bismaleimide resin with nano ceramic powder. Background technique [0002] As we all know, cyanate resin has good mechanical properties, dielectric properties, heat resistance and so on. Because of its outstanding dielectric properties, dielectric constant (2.8-3.2), dielectric loss (0.002-0.008), it can be used in structural materials, wave-transmitting materials, dielectric functional materials, etc., used in aerospace, electronic information, etc. field. However, at present, cyanate ester resins have disadvantages such as poor manufacturability, poor toughness, short pot life and storage period, poor hardness, and poor wear resistance. [0003] Bismaleimide resin is widely used in aerospace, electronics, rail traffic lights and other fields due to its excellent heat and humidity resistance, low moisture a...
