Light hygroscopic mineral wool fiber formula and fiber forming process thereof

Abstract

The invention discloses a light hygroscopic mineral wool fiber formula. The formula is prepared from the following raw materials in parts by weight: 10 to 15 parts of polytetrafluoroethylene fiber; 55-70 parts of plant fibers, 22 to 28 parts of inorganic reinforced fibers; 15 to 20 parts of shell powder; 15 to 25 parts of mineral wool slag; 22-26 parts of fly ash, 14 to 20 parts of closed cell perlite; 22-31 parts of graphene, 3-9 parts of nano zirconium oxide, 3-5 parts of siliceous sedimentary rock, 3-10 parts of plant starch, 5-8 parts of glutinous rice glue, 15-25 parts of activated carbon, 5-8 parts of diatomite, 5-8 parts of resin, 5-10 parts of photocatalytic powder, 10-15 parts of negative ion mineral powder, 30-45 parts of granular cotton and 20-35 parts of water. Through mutual cooperation of designed polytetrafluoroethylene fibers, inorganic reinforced fibers, plant fibers, shell powder, activated carbon, granular cotton, graphene, a first grinding hammer, a second grindinghammer, a first grinding seat and a second grinding seat, the grinding efficiency is improved; in the chemical fiber process, because the molten magma contains more mineral wool slag balls, the thermal conductivity coefficient is higher, the tensile property is lower, the performance is insufficient and the like.

Description

technical field [0001] The invention belongs to the technical field of mineral wool fiber processing, and in particular relates to a lightweight hygroscopic mineral wool fiber formula and a fiber-forming process thereof. Background technique [0002] Mineral wool and its products are light, durable, non-combustible, non-rotten, and free from moths, etc. They are excellent heat insulation and sound-absorbing materials. Cotton-like short fibers made from silicate melts, including slag wool, rock wool, glass wool and ceramic fibers, etc., generally only refer to the first two in my country. The earliest mineral wool obtained from the Hawaiian crater was called "Fall's hair". Those whose main raw materials are metallurgical slag or fly ash are called slag wool; those whose main raw materials are rocks such as basalt are called "rock wool". Crushing the raw materials into a certain particle size, adding additives, etc. for batching, and then melting in the furnace, forming cott...

AI Technical Summary

Problems solved by technology

[0004] Mineral wool board is also commonly known as mineral wool sound-absorbing board. In the ceiling, we often use mineral wool board to effectively reduce indoor noise and ensure the comfort of the indoor environment. However, there are still various deficiencies in the mineral wool fibers that appear on the market. , cannot meet the demand of production

[0005] The toughness and mechanical strength of the existing mineral wool fibers are low, so that when the molten raw materials are processed into chemical fibers, in order to avoid the fiber filaments from breaking, the applied centrifugal force is limited, resulting in a large thickness of the fiber filaments, and in the process of chemical fibers, Because the molten magma contains more mineral wool slag balls, resulting in high thermal conductivity, low tensile properties, and insufficient performance, we propose a light-weight hygroscopic mineral wool fiber formula and its fiber-forming process
