Abstract

The invention discloses a method for preparing nanometer ATO dispersing slurry fast, efficiently and cheaply. The method comprises the following steps: (1) successively adding silane coupling agent and ATO powder in water under stirring according to a weight ratio of to 0.005-0.02:1 to obtain ATO powder suspending liquid with the solid content of 16-55%, adjusting the pH value with alkaline solution to 9-11; (2) placing the ATO powder suspending liquid obtained by the step (1) in a ball mill to perform ball milling for 0.5-7.5 hours which adopts zirconium beads as ball-milling beads, removing the ball-milling beads to obtain slurry, fast adjusting the pH value with alkaline solution to 6-8; and (3) centrifuging the slurry obtained by the step (2) in a centrifugal machine under the rotate speed of 1000-4000rpm to obtain the nanometer ATO dispersing slurry. The preparation method of the invention is characterized by fast speed, electricity-saving and high efficiency; the average diameter of the particles of the prepared slurry is 25-50nm, the solid content is 15-50%, and the dispersing effect is very good.

Description

(1) Technical field

[0001] The invention relates to a method for preparing ATO nanometer dispersion slurry. (2) Background technology

[0002] Building energy conservation is the basic energy utilization policy that our province has always adhered to. Among all kinds of energy consumption, building heating and air conditioning energy consumption occupies a considerable proportion. Doors and windows, as transparent and openable envelopes in house construction, are the weakest part of winter heat preservation and summer heat insulation. When we turn on the air conditioner to heat or cool down, the energy lost from ordinary single-layer glass windows is as high as 50% of the building's energy consumption. Today, building energy conservation is being promoted in an all-round way. After the thermal insulation performance of the wall has been greatly improved, Doing a good job of thermal insulation of doors and windows, especially the glass that accounts for 80% of the area of ​...
