More Information
Summary:The present invention provides a nanoscale calcium borate and its using purpose. The invention adopts adding boric acid, borax and calcium oxide in high pressure kettle according to mol ratio 32:1:4, the product is obtained by further adding 160-200ml distilled water to make pH of the reactant is 5-6, the compactness of the reaction kettle is between 0.50-0.75, moving the product to beaker after reacting 3-4 hours under the temperature 230-245 Celsius in a sealing condition, removing the upper clarifying solution after silencing by filling distilled water, washing again and again to make pH achieve neutral then drying. The width of single nanowires crystal is 90nm-110nm, the length is above 1 mum, the chemical formula is 2CaO.3B2O3.H2O. The nano-calcium borate may add in polymer system, used for inflaming retarding of rubber, nylon, plastic, paint, glass fibre reinforced plastic, coat, paper industry.
