Embodiment 1

[0020] 5 grams of acrylonitrile, 0.36 grams of sodium lauryl sulfate, 0.36 grams of OP-10, 0.15 grams of sodium metabisulfite, 0.24 grams of anhydrous sodium acetate, 0.15 grams of glacial acetic acid, 0.03 grams of EDTA, 200 grams of water, 0.15 grams of montmorillonite Soil, 0.15 g of silicon dioxide was added to a 500 ml four-neck flask, stirred thoroughly, and then ultrasonically oscillated for 30 minutes, and then the reactor was heated to 60° C. under magnetic stirring. After reaching the reaction temperature, 25 grams of acrylonitrile and an initiator solution (0.3 grams of ammonium persulfate, 16 grams of water) were evenly fed through a constant pressure funnel. After 5 hours of reaction, the material was discharged to obtain a white emulsion. After the emulsion is demulsified with a saturated sodium chloride solution, it is washed, dehydrated and dried to obtain a polyacrylonitrile nanocomposite material. The reaction conversion rate is 77.30%, the temperature for 2...

Abstract

A composite polyacrylonitrile-binary nano-component material with high stretch strength and high temp resistance is prepared from acrylonitrile and nano-component composed of nano-SiO2 and nano-montmorillonite through in-situ polymerizing.

Description

technical field [0001] The invention relates to a polymer / nanometer composite material, in particular to a polyacrylonitrile / binary nanometer component composite material. Background technique [0002] In-situ polymerization method is used to introduce nanomaterials to modify polymers to exert their unique properties in light, electricity, magnetism, biology, medicine, machinery, etc., and many research and application results have been obtained. Commonly used inorganic nanomaterials include silicate, calcium carbonate, SiO 2 、TiO 2 , SiC, Al 2 o 3 , mica, silk powder, etc. According to different matrix resins, nano-composite materials can be classified into: nano-nylon, nano-polyolefin, nano-polyester, nano-polyoxymethylene, etc. The world's earliest industrial application of nano-plastics was the nano-nylon 6 for automobile timer covers jointly developed by Japan's Toyota Central Research Institute and nylon resin factory Ube Industries (UBE) in 1991. It opened the p...
