Embodiment Construction

[0011] Various methods such as mechanical grinding and chemistry can be used to make nano-additives from silicon dioxide and aluminum oxide respectively, but it is best to use gas phase ion treatment to prepare nano-additives. The particle size of nano-additives prepared by this method is small and relatively Large surface area, strong chemical activity, low cost, easy to mix evenly. Get silicon dioxide and Al2O3 nano-additives in a prescribed ratio (with the prior art), mix them evenly with cellulose, and make spinning solution, and the weight of the nano-additives is preferably 20 to 30% of the mixture weight, preferably 20%. ~30 kg of nano-additives are mixed with 70~80 kg of cellulose. For example, using a static mixer, the method of melt blending is used to prepare the spinning solution, so that the nanoparticles are relatively easy to disperse evenly in the spinning solution, and they are not oxidized or agglomerated. After the nano-spinning solution is made, it can be ...

Abstract

A fire-retarding refractory nano fibre is prepared through preparing nano additive from SiO2 and Al2O3, mixing it with cellulose, preparing spinning dope, and spinning. Its advantages are high strength and elongation, low moisture regain, and high refractory effect (1300 deg.C).

Description

Technical field: [0001] The invention relates to a production method of flame-retardant fibers, in particular to a production method of nanometer high-temperature-resistant flame-retardant fibers. Background technique: [0002] The application of high temperature resistant and flame retardant textile materials is very extensive, such as aircraft, ships, trains, automobiles, and other means of transportation, interior decoration materials for large buildings and halls, protective clothing for firefighting and other special staff, transportation and Canopy materials used in construction sites and other places, high temperature resistant and flame retardant filter materials used in various places such as steel plants or thermal power plants, etc. High temperature resistant and flame retardant textile materials are mainly achieved through the following two ways: one is to carry out flame retardant post-treatment on textile materials, which is low in cost, but the flame retardanc...
