The present application relates to the technical field of silicone rubber material, in particular to a sericite modified silicone rubber material and a preparation method thereof.The present application overcomes the problems of poor dispersion of sericite in the organic silicon matrix and poor compatibility of fluorosilicon and common silicon.The silicone rubber material is prepared from polysiloxane hybrid base glue prepared by in-situ polymerization of fluorine-containing / ethenyl double modified sericite, fluorosilicon raw rubber, methylphenylvinyl silicone rubber, MQ silicone resin, hydrogen-containing silicone oil and vulcanizing agent;the preparation process involves double functional group grafting on the surface of sericite, monomer in-situ ring-opening polymerization coating, multiphase blending to build interpenetrating network and hydrogen-containing silicone oil chain extension to cooperate with gradient vulcanization, through building a rigid-flexible stereo enhanced network, the material is endowed with excellent oil resistance, heat resistance and high mechanical strength, and can be used in the field of automobile manufacturing.

This invention relates to the field of polyether material preparation, and provides a low-foaming block copolymer ether and its preparation method. The method involves reacting a hydroxyl-terminated polyoxyethylene-polyoxypropylene block copolymer with propyltriethoxysilane isocyanate, followed by hydrolysis-condensation to construct a block copolymer ether with siloxane-containing nanoclusters at the end groups. By controlling the number-average molecular weight of the polyether backbone, the content of ethylene glycol oxy units, the content of propylene glycol oxy units, the amount of silane introduced, the degree of hydrolysis-condensation, and the average particle size of the siloxane nanoclusters, low initial foam height, low 5-minute foam height, suitable cloud point, and low residue are achieved. This solves the problem of simultaneously achieving persistent low foaming with low viscosity, a wide processing window, structural uniformity, water solubility, and compatibility stability, and has good industrial application value.

This disclosure relates to a method and system for preparing an alkaline slag-calcium sulfate composite activated product, belonging to the field of carbon fixation material preparation technology. The method includes: firstly, differentially mechanically activating alkaline slag and calcium sulfate to obtain pretreated powder; then, performing microwave-chemical coupling activation treatment; and finally, intermittent ultrasonic dynamic aging to obtain a precursor for carbon fixation filling materials. The system includes a dual-cavity graded ball mill module, a microwave-chemical coupling activation module, and an ultrasonic dynamic aging module connected in sequence. This application significantly improves the system's reactivity and structural uniformity through multi-stage synergistic activation, effectively solving technical defects such as salting out and cracking, and can greatly improve the carbon fixation rate and long-term mechanical strength, realizing the high-value utilization of bulk industrial solid waste and efficient carbon dioxide sequestration. This application has a simple process, low energy consumption, and strong controllability, and is suitable for large-scale industrial applications of carbon fixation filling in mines.
