This invention discloses an early-strength, high-stability road grouting repair material and its preparation, belonging to the field of solid waste utilization and road grouting reinforcement technology. The raw materials of the early-strength, high-stability road grouting repair material of this invention include multi-source solid waste aggregates and a water-reducing agent; the multi-source solid waste aggregates, by mass percentage, include: 6.6 wt% fly ash, 5-15 wt% rapid-hardening sulfoaluminate cement, 64-74 wt% mineral powder, 13.4 wt% desulfurized gypsum, and 1% carbide slag. This invention constructs a quaternary solid waste system of fly ash-desulfurized gypsum-mineral powder-carbide slag, synergistically forming a slurry composite system with rapid-hardening sulfoaluminate cement and a water-reducing agent, and precisely controls the concentration of raw materials. During hydration, this system can generate supporting crystals, which not only provide high early-stage stone strength for the road grouting material, but also, due to its good stability, ensure high stone strength stability in the later stages.

Provided is a method for producing a resin composition for secondary battery electrodes, the method comprising adding a binder resin to a carbon nanotube dispersion liquid which contains carbon nanotubes, a dispersing agent, and a nonaqueous dispersion medium and in which the product (X×Y) of the complex elastic modulus X(Pa) and the phase angle Y(°) at 25°C and 1 Hz obtained by dynamic viscoelastic measurement is 30 to 1,700 and the phase angle is 3° to 90°.

The invention relates to the technical field of building materials, in particular to EPS (expandable polystyrene) reinforced foam concrete and a preparation method thereof, and the EPS reinforced foam concrete is prepared from the following raw materials in parts by weight: 50-60 parts of cement, 20-25 parts of water, 0.8-1.2 parts of EPS, 0.8-1.2 parts of foam group, 0.01-0.1 part of rubber powder and 0.4-0.9 part of water reducing agent. Through cooperation of the EPS particles, the foam group, the cement, the water reducing agent and the rubber powder, a light porous structure which takes EPS and closed foam as cores and is extremely low in volume weight is formed, meanwhile, by means of a compact gelling inclusion and a reinforced interface, the material obtains compression resistance and breaking strength far superior to those of conventional foam concrete, shrinkage cracking is effectively inhibited, and the service life of the material is prolonged. The unification of light weight, high strength and toughness is realized.

The invention relates to the technical field of separation and extraction of natural products, in particular to a method for supercritical separation and extraction of astaxanthin, which comprises the following steps: (1) weighing raw material components in parts by weight; (2) mixing a biomass raw material rich in astaxanthin with the functionalized deep-eutectic solvent, and performing physical field enhanced extraction to obtain an extracting solution; (3) filtering the extracting solution through a vibrating membrane, and purifying to obtain a trapped fluid containing astaxanthin; and (4) carrying out supercritical CO2 back extraction on the trapped fluid, separating to obtain an astaxanthin product, and recovering the functional eutectic solvent. According to the method, continuous membrane separation and purification under the eutectic solvent system are realized, the purity of astaxanthin and the proportion of all-trans astaxanthin are maintained while the extraction rate of astaxanthin is increased, the solvent can be recycled after being recovered, and the production cost and waste liquid discharge are greatly reduced. All the raw materials are nontoxic and harmless, no organic solvent is used in the technological process, and good application prospects are achieved.
