The invention provides a production method of cement clinker by calcination with the combustion performance of oxygen-rich reinforced lignite. A combustor with four wind channels is adopted, wherein coal wind, cyclone wind and axial-flow wind serve as primary wind, the primary wind is air and the volume of the primary wind accounts for 8% total wind volume; center wind is also air and the volume of the center wind accounts for lower than 1% total wind volume; secondary wind and tertiary wind are oxygen-rich gas with oxygen concentration of 25-90%, and the temperature of a kiln head is controlled between 980 DEG C and 1020 DEG C when the secondary wind enters the kiln head. The combustion performance of the oxygen-rich reinforced lignite is applied to the calcinations of cement clinker, the limitation that at present lignite can not be used alone as a fuel during production of cement clinker is broken, and the production method has significant economical and social benefits.

The invention relates to a waterborne heat-insulating flame-retardant multifunctional nano coating and a preparation method thereof. The coating consists of the following components in part by weight: 48 to 52 parts of waterborne resin and 30 to 50 parts of nano pigment fillers (nano titanium dioxide, nano titanium dioxide-coated hollow glass microspheres, nano titanium dioxide-coated hollow ceramic microspheres and nano antimony-doped tin dioxide (ATO) particles), size and auxiliary materials such as film-forming additive and coupling agent. The preparation method includes the steps that: the nano fillers and the size are first dipped into the waterborne resin, the auxiliary materials are then sequentially added and stirred, and thereby the heat-insulating flame-retardant multifunctional nano coating is obtained. The processing technique is simple, the component proportion is reasonable, and the prepared coating has the advantages of high heat resistance, high reflectivity, high radiative heat conductivity, certain fire resistance, high-efficient heat insulation, excellent mechanical and chemical properties, environment-friendliness, stain resistance, flame retardance and energy saving. The coating can be coated on outside facilities such as outer walls and building roofs.
