Abstract

The invention discloses a refractory brick with anticorrosion heat reflection coatings and a preparation method of the refractory brick. The refractory brick comprises a refractory brick body; the outer wall of the refractory brick is coated with two coatings with the first coating being a titanium oxide coating and the second coating being a tin oxide coating from outside to inside. The refractory brick used for a garbage incinerator is subjected to surface plating treatment, the two coatings are arranged from outside to inside, the titanium oxide coating is arranged on the outside, the tin oxide coating on the inside, a combination of titanium oxide and tin oxide is high in melting point and is stable in most high-temperature acid-alkaline environments, and the refractory brick can be protected in acid and alkaline chemical environments by using the two coatings, thus, the inner incinerator wall of the garbage incinerator is resistant to acid and alkali, the service life of an incinerator body is prolonged, infrared rays in the incinerator can be reflected, heat in the incinerator body is preserved, the heating speed of the incinerator is increased, and the universality is improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a refractory brick with an anti-corrosion heat-reflecting coating and a preparation method thereof. Background technique [0002] At present, the method of increasing the corrosion resistance of the waste incinerator wall is to improve by using corrosion-resistant refractory bricks. These corrosion-resistant refractory bricks realize the corrosion resistance of refractory bricks by modulating the internal composition. Although the method of the inner furnace wall has a better effect, its versatility is poor, which makes the manufacture and maintenance of the furnace body more complicated. [0003] At present, the common method for coating the inner furnace wall with infrared reflective coating is to mix the powder (paint) with infrared reflective properties with water, and then add a cross-linking agent to prepare a slurry and apply it on the target substra...
