This utility model relates to the field of textile fabrics, and more particularly to a green and environmentally friendly fabric, comprising a reinforcing surface layer and an environmentally friendly base layer. A heat-melting yarn is disposed between the reinforcing surface layer and the environmentally friendly base layer. The environmentally friendly base layer is made of regenerated cellulose fibers. The top and bottom ends of the heat-melting yarn are fixedly connected to the reinforcing surface layer and the environmentally friendly base layer, respectively. The heat-melting yarn is woven from heat-melting fibers. The reinforcing surface layer is woven from fiber bundles, which include tensile fibers, flame-retardant fibers, absorbent fibers, polyester fibers, and corrosion-resistant fibers. The tensile fibers, flame-retardant fibers, absorbent fibers, polyester fibers, and corrosion-resistant fibers are bundled together to form a tight structure. This invention solves the technical problems of insufficient environmental performance and functionality in traditional fabrics.

This invention discloses a method for preparing a lightweight spinel-corundum-aluminate refractory material. First, by simulating the microstructure of sintered magnesia, a multiphase material is constructed with magnesia-alumina spinel as the main crystalline phase and calcium aluminate as the intergranular and secondary crystalline phases. This results in a spinel-calcium aluminate-calcium disaluminate multiphase material with controllable crystalline phase distribution and pore composition. Next, using this multiphase material as aggregate and corundum-spinel as the matrix, the materials are batched according to a specific particle size distribution, pressed into shape, and fired at high temperature. By introducing the spinel-calcium aluminate-calcium disaluminate multiphase material and utilizing calcium ion migration, this invention enables the preparation of a lightweight spinel-corundum-aluminate refractory material with microporous aggregate and a dense matrix. The material's load-bearing capacity at both room temperature and high temperature is not lower than (or even higher than) that of heavy refractory materials of the same material. This synergistically improves the thermal insulation, high-temperature load-bearing capacity, and resistance to media erosion of this type of lightweight refractory material.
