Nano-attapulgite (ATP) is a layered silicate mineral with abundant reserves, large specific surface area, and low cost. The unique structure of ATP has attracted wide attention in the field of adsorption. In this study, a preparation technology of ATP grafting basalt fiber (BF) was proposed by chemical grafting method based on the idea of plant root bionics. The optimal preparation process of ATP grafting BF was determined through the tests of asphalt absorption performance, thermal stability performance, and segregation dispersion performance. The mechanism of ATP grafting BF was analyzed by micro-morphology, functional group changes, and elemental composition. Finally, the adsorption performance of ATP grafting BF was investigated on the basis of adsorption kinetics model and molecular dynamics simulation. The study results indicated that ATP-BFHCl had better compatibility and wettability with asphalt. The quasi-second-order kinetic equation could better fit the adsorption process of ATP-BFHCl on asphaltene, which indicated that ATP-BFHCl adsorbed asphaltene with chemisorption or ion exchange. The diffusion coefficient and diffusion activation energy of the saturate and the aromatic were larger, indicating a smaller molecular weight and faster movement, and lightweight components of asphalt are more easily adsorbed on the surface of ATP. The diffusion activation energy of asphaltene is the smallest and the reaction is the easiest to take place, which indicates that it is the first to react during temperature increase. The research results can provide a theoretical basis and technical support for BF surface treatment technology.

Cyanate (CE) resin and ultrahigh‐molecular‐weight polyethylene (UHMWPE) fiber are respectively important matrix and reinforcing material for lightweight and high wave‐transparent composites. However, the preparation and application of the composites is limited by the mismatch of molding temperature between CE resin and UHMWPE fiber. The best method to solve this problem is to catalyze the CE resin curing reaction and reduce its molding temperature from 270 to 135°C, which is the upper heat‐resistance temperature of UHMWPE fiber. In this study, the polysulfide catalyst (PSC) was used to catalyze CE resin curing reaction, reduce the curing reaction activation energy and the molding temperature. The apparent activation energy of the CE‐PSC resin decreases from 107.2 to 60.7 kJ mol−1, and the glass transition temperature of the CE‐PSC resin is 257.2°C, flexural strength and tensile strength are 120.2 and 60.8 MPa, respectively. As a result, the CE‐PSC/UHMWPE fiber composites, which are molded at the matching temperature of 135°C, have low density of 1.05 g cm−3, low dielectric constant of 2.4, low dielectric loss of 0.006, and high wave transmittance of 92.2%. Therefore, the CE‐PSC/UHMWPE fiber composites have wide application prospect in the field of light weight and high wave‐transparent composites.Highlights A novel catalytic CE resin can be cured at 135°C with low dielectric properties. The processing temperature mismatch between CE and UHMWPE fiber was solved. Catalytic CE/UHMWPE composites have lightweight and high wave‐transparent properties.
