High-temperature far infrared radiation energy-saving composite coating and preparation method thereof

Abstract

The invention discloses a high-temperature far infrared radiation energy-saving composite coating and a preparation method thereof, aiming at providing a composite coating with the advantages of stable structure, low production cost and little environment pollution. The high-temperature far infrared radiation energy-saving composite coating is technically characterized by comprising the followingcomponents in percent by weight: 25-30 percent of Baihou asbolite, 10-15 percent of Yinjiang kaolin, 5-7 percent of manganese oxide, 6-8 percent of ferric oxide, 4-6 percent of chromic oxide, 15-20 percent of Guodong mortar, 10-12 percent of aluminum oxide, 6-8 percent of zircon sand, 3-5 percent of titanium oxide and 1-3 percent of lanthanum oxide.. The preparation method comprises the steps of:1, crushing the Baihou asbolite and the Yinjiang kaolin, and screening; 2, respectively screening the aluminum oxide, the manganese oxide, the zircon sand, the ferric oxide, the titanium oxide and the chromic oxide; 3, respectively loading all screened components in a sagger and then entering a kiln for calcining; and 4, smashing and blending calcined block materials, grinding through a wet process ball grinder, and screening to obtain the composite coating. The invention belongs to the technical field of coating preparation.

Description

Technical field [0001] The invention relates to a composite paint; specifically, a high-temperature far-infrared radiation energy-saving composite paint and a preparation method thereof; belonging to the technical field of paint preparation. Background technique [0002] my country's daily-use ceramics production accounts for about 65% of the world, and the annual export volume reaches more than 8 billion pieces, accounting for more than 70% of the world's total exports. However, due to the relatively thin foundation of my country's ceramic industry and the relatively backward product firing equipment, there is a problem of high energy consumption. Regarding the burning energy consumption per unit product of daily-use porcelain, the energy consumption of domestic gas-fired tunnel kilns is 1.00-1.35Kg standard coal / Kg porcelain. The burning energy consumption accounts for more than 30% of the total cost during the entire production process. The energy consumption of foreign gas-f...
