The utility model relates to the technical field of carved decorating parts, and discloses a flame-retardant high-percentage-of-closed-area carved decorating part which comprises an outer frame body and a fixing frame, the inner wall of the outer frame body is fixedly connected with a connecting frame, the fixing frame is arranged in the outer frame body, and the connecting frame is fixedly connected with the fixing frame. The front ends and the rear ends of the outer frame body and the fixed frame are fixedly connected with first high-closed-hole filling layers respectively. According to the flame-retardant high-percentage-of-closed-pore carved decorating part, the first high-percentage-of-closed-pore filling layer, the first filling material, the second high-percentage-of-closed-pore filling layer and the second filling material are arranged, and the relationship that the first filling material is aluminum hydroxide and the second filling material is expanded graphite is utilized, so that the flame-retardant high-percentage-of-closed-pore carved decorating part is formed; aluminum hydroxide and expanded graphite are chemically copolymerized or physically mixed to improve the flame retardance, when a fire occurs, a closed-pore structure expands to form a dense carbonized layer, flame spreading is delayed, toxic smog is not released, so that the material is safer to use, the flame retardance is improved, and the problems that the flame retardant effect is poor and the percentage of closed pore is low are solved.

This utility model discloses a high tensile strength and corrosion resistance cable for offshore wind power, comprising a cable core consisting of a central tensile rope and multiple moisture-proof insulated cores; the moisture-proof insulated cores are tangent to the central tensile rope; moisture-proof and water-blocking filler is used to fill the gaps in the cable core; a shielding aluminum-plastic composite tape is wrapped around the cable core; a corrosion-resistant composite layer is provided outside the shielding aluminum-plastic composite tape; a flexible buffer layer is extruded outside the corrosion-resistant composite layer; a steel tape armor layer is provided outside the flexible buffer layer; a PTFE film tape is overlapped and wrapped around the steel tape armor layer; and an outer sheath is extruded outside the PTFE film tape. By optimizing the cable structure and material selection, the tensile strength and corrosion resistance of the cable are improved, while maintaining the cable's flexibility and service life, to meet the high requirements of offshore wind farms for cables.

The application relates to a resin composition and a preparation method and application thereof. The resin composition is prepared from the following materials, the materials are in parts by mass, including 37.5-43.5 parts of polyether polyol, 37.5-43.5 parts of isocyanate, 2-5 parts of composite auxiliary materials, 1-2 parts of heavy calcium and 10-18 parts of quartz, wherein the composite auxiliary materials include 1-2 parts of sintered molecular sieve, 1-2 parts of re-burned glass pumice and 3-6 parts of glycerol in parts by mass. The foamed resin support prepared from the resin composition has excellent high-temperature resistance and durability.

The application discloses a light autoclaved aerated concrete block and relates to the technical field of concrete blocks.The light autoclaved aerated concrete block comprises the following raw materials: cement, lime, base material, modified palygorskite, calcium sulfate dihydrate, aluminum paste, foam stabilizer and deionized water.In the application, the fibrous structure of the modified palygorskite can form a network framework in the slurry, fill the internal pores and block the capillary channels, so that the overall structural compactness and surface strength of the block are improved, and the drying shrinkage and water absorption are reduced.The alkyl benzene sulfonic acid sodium in the foam stabilizer can reduce the surface tension of the slurry and promote the generation of a large number of bubbles.Nano silicon dioxide can form a rigid support framework in the bubble liquid film to prevent the bubbles from merging or breaking.Polyvinyl alcohol forms an elastic protective film on the bubble surface, prolongs the bubble life, greatly improves the block closed porosity, guarantees the light weight of the block, reduces the drying shrinkage due to the uniformity of the pores, and improves the impermeability and overall strength.
