Abstract

The invention provides a thermal insulation coating and a preparation method thereof. The thermal insulation coating comprises 10 to 20 parts of nano silicate inorganic binder and 15 to 20 parts of organosilicon modified Solution, 10-15 parts of fumed silica gel, 25-35 parts of nano hollow microspheres, 5-15 parts of inorganic hollow fiber powder, 2-8 parts of nano-rare earth oxide, 1-5 parts of auxiliary agent, 0.5 parts of water. The thermal insulation coating provided by the present invention, through the synergistic effect of the organosilicon modification solution and other components, makes the thermal insulation coating have excellent thermal insulation performance, and also has low thermal conductivity, corrosion resistance, impact resistance, and fire prevention. It has the advantages of waterproof, simple construction, and strong adhesion to the coke oven body.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation coating and a preparation method thereof. Background technique [0002] Coke oven is a complex industrial furnace with huge energy consumption. The heat utilization efficiency of each coke oven is about 76%, so 24% of the heat is not used; among them, the heat wasted by the surface heat dissipation of the coke oven accounts for about 11% of the unused heat; It not only causes a waste of energy, but also causes heat pollution. [0003] On the one hand, the surface heat dissipation of the coke oven is caused by the operation process, such as the heat dissipation caused by the roof area, combustion chamber area, furnace bottom area and regenerator area of ​​the coke oven and the opening of the furnace door during the coke pushing operation; On the one hand, it is caused by the heat dissipation of the coke oven body; after the heat insulation of the coke oven ...
