▎ 摘 要
NOVELTY - Graphene/carbon nanotube modified epoxy resin asphalt material comprises 1 part mass component (A), and 1-4.5 parts mass component (B). The component (A) comprises 100 parts mass bisphenol A type epoxy resin, 0.5-10 parts mass graphene/carbon nanotube composite reinforcing agent and 0.2-0.5 part mass coupling agent. The component (B) comprises 50-100 parts mass asphalt, 1-20 parts mass aliphatic dicarboxylic acid, 1-20 parts mass aliphatic dicarboxylic acid polyanhydride, 5-50 parts mass epoxy resin curing agent and 0.2-1 part mass accelerator. USE - As graphene/carbon nanotube modified epoxy resin asphalt material. ADVANTAGE - The modified epoxy resin asphalt material has more excellent performance, significantly improves the uniform dispersion of graphene oxide in the resin system, and does not easily cause the phenomenon of agglomeration to form a precipitate, which increases the compatibility of epoxy resin and asphalt. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the modified epoxy resin asphalt material, involving (i) uniformly dispersing graphene powder in an aqueous phase under the action of ultrasound to prepare a dispersion liquid with a graphene content of 0.1 g/l, (ii) taking the dispersion liquid, adding iron-based nano catalyst, performing hydrothermal reaction under stirring for 15 minutes, naturally cooling to room temperature, centrifuging the product, washing and drying to obtain a reaction product, (iii) growing nanocarbon on the surface of the reaction product by chemical vapor deposition of a carbon source to obtain a graphene oxide/carbon nanotube composite reinforcing agent, (iv) adding the prepared reinforcing agent to bisphenol A type epoxy resin, and infiltrating graphene/carbon nanotube, (v) slowly adding the coupling agent while stirring, stirring with a high-speed shear, ultrasonically dispersing, and grinding with a three-roller to obtain component (A), (vi) adding the mixture of aliphatic dicarboxylic acid, aliphatic dicarboxylic acid polyanhydride, epoxy resin curing agent, accelerator and asphalt to a 140 degrees C stirring tank, and stirring until the system viscosity is uniform, so as to obtain component (B), and (vii) mixing components (A) and (B) and stirring for 5-30 minutes to obtain the product.
