Preparation method of novel high-temperature-resistant flame-retardant ATO nano-powder material

Abstract

The invention discloses a preparation method of a novel high-temperature-resistant flame-retardant ATO nano-powder material, which comprises the following steps: weighing raw materials, conducting drying, crushing, and extruding and granulating, and carrying out ball milling and forming, wherein the raw materials comprise 168-172 parts by weight of ATO nano-powder, 108-118 parts by weight of silicone rubber, 15-25 parts by weight of high-polymerization-degree crystal form II ammonium polyphosphate, 12-20 parts by weight of nano mesoporous molecular sieve, 8-12 parts by weight of ceramic powder, 2-8 parts by weight of nano zinc oxide powder, 2-6 parts by weight of rhodium oxide powder, 3-9 parts by weight of barium sulfate whisker, and the like. The preparation method is scientific and reasonable; the processing steps and the processing parameters are optimized; a nano-mesoporous molecular sieve, the ceramic powder, nano-silicon carbide, cobalt and other components are added, so that the high-temperature-resistant and flame-retardant performance of the ATO nano-powder material are improved; and the ATO nano-powder material prepared through the preparation method is uniform in texture and good in dispersity and has excellent high-temperature-resistant, flame-retardant, tensile-resistant, wear-resistant, antistatic and acid and base resistant properties.

Description

technical field [0001] The invention relates to the technical field of ATO nano powders, in particular to a method for preparing a novel ATO nano powder material with high temperature resistance and flame retardancy. Background technique [0002] ATO, also known as antimony-doped tin dioxide, is mainly composed of tin oxide and antimony oxide, and its particle size is mostly in the range of 5-80 nanometers. Nano-ATO powder, blue or light blue powder in appearance, has the characteristics of high temperature resistance, corrosion resistance, and good dispersibility. Has excellent optical (absorbing ultraviolet rays, intercepting infrared rays) and electrical properties. Utilizing its good electrical conductivity and optical properties, it is widely used in textiles, coatings, chemical fibers, polymer films and other fields as antistatic agents, ultraviolet absorbers, and infrared shielding agents. , Safety, antistatic, heat insulation, shielding electromagnetic waves, etc. ...

Problems solved by technology

However, since our country does not have a relatively complete flame-retardant legal specification, the total production and use of flame-retardant products in my country still lag far behind developed countries.
