Abstract

An antiaging agent for high-temperature resistant infrared coatings and a preparation method thereof, characterized in that: a. In parts by weight, 20-50 parts of silicon dioxide, 15-32 parts of silicon hexaboride, 15-32 parts of hexaboron Calcium chloride, 1-8 parts of boron trioxide, 3-12 parts of borosilicate glass are mixed and then added to the mixing tank for pre-mixing for 5-30 minutes; b. Then the mixture is added to the fluidized bed jet mill for shaping and mixing, and the classifier 1200~2300r / min, to obtain mixed powder with an average particle size of 0.1~4μm; c. The mixed powder is placed in a high-temperature furnace, heated to 850~1100℃ at 2~7℃ / min, kept for 1~3h, and sintered with furnace cooling d. The sintered material is crushed to an average particle size of 0.5-5mm, added to a fluidized bed jet mill for ultra-fine, and the classifier is 2400-3000r / min to obtain a high-temperature-resistant infrared coating with an average particle size of 0.1-2μm. Aging agent. The invention has simple composition and convenient preparation steps; it is stable and has good high-temperature infrared radiation ability, anti-oxidation ability and anti-washing ability in high-temperature complex atmosphere.

Description

Technical field [0001] The present invention belongs to the technical field of high temperature protection technology, and more particularly to an anti-aging agent for high temperature infrared coatings and a preparation method thereof. Background technique [0002] In recent years, the research and development and application of high-temperature infrared coatings have been widely concerned at home and abroad, and a new number of new high-temperature infrared coatings have emerged, and are applied to new fields of high temperature equipment, such as glass melting kiln; but these high temperatures The infrared coating still has a problem of poor anti-aging resistance, making its infrared spectral radiation in a complex high temperature atmosphere, decreasing with the extension of the use time, seriously affecting its service and energy saving effect. Inventive content [0003] It is an object of the present invention to solve the problem of poor aging resistance in existing high ...
